The annual interest on a $2000 investment exceeds the interest earned on a $1000 investment by $55.The $2000 is invested at a 0.5% higher rate of interest thanthe $1000. What is the interest rate of each investment?

Answers

Answer 1

from the question;

The annual interest on $2000 ivestment exceeds the interest earned on $1000 investment by $55 and the $2000 is invested at a 0.5% higher rate of interest than the $1000

let P = principal

I = interest

R = interest rate

first

[tex]\begin{gathered} \text{Let} \\ P_1=\text{ \$1000 investment} \\ I_1\text{ = x} \\ R_1\text{ = r\%} \end{gathered}[/tex]

given the above information on $1000 investment above and the information above

[tex]\begin{gathered} \text{let } \\ P_2\text{ = \$2000 investment} \\ I_2\text{ = x + 55} \\ R_2\text{ = (r + 0.5)\%} \end{gathered}[/tex]

applying the formula for Interest

[tex]\text{Interest I = }\frac{P\text{ }\times T\text{ }\times\text{ R}}{100}[/tex]

for $1000 investment

[tex]\begin{gathered} u\sin g\text{ the interest formula and inserting the appropriate values} \\ we\text{ get} \\ x\text{ = }\frac{1000\text{ }\times\text{ 1 }\times\text{ r}}{100} \\ x\text{ = 10r -------- (1)} \end{gathered}[/tex]

for $2000 investmet

[tex]\begin{gathered} u\sin g\text{ the interest formula and applying the appropriate values} \\ we\text{ get} \\ x\text{ + 55 = }\frac{2000\text{ }\times\text{ 1 }\times\text{ (r + 0.5)}}{100} \\ x\text{ + 55 = 20(r + 0.5)} \\ x\text{ + 55 = 20r + 10} \\ x\text{ - 20r = 10 - 55} \\ x\text{ - 20r = -45 ----------(2)} \end{gathered}[/tex]

combine the two equations;

[tex]\begin{gathered} x\text{ = 10r -------------(1)} \\ x\text{ - 20r = - 45 ---------(2)} \end{gathered}[/tex]

substitute x=10r into equation 2; we get

[tex]\begin{gathered} 10r\text{ - 20r= -45} \\ -10r\text{ = - 45} \\ \text{divide both sides by -10} \\ \frac{-10r}{-10}\text{ = }\frac{-45}{-10} \\ r\text{ = 4.5} \end{gathered}[/tex]

Therefore,

the interest rate on $1000 investment = 4.5%

The interest rate on $2000 investment is (4.5 + 0.5)% = 5.0%

b. 4.3 cm

c. 325.4 seconds

STEP-BY-STEP EXPLANATION:

The first thing is to calculate the value of the volume, which is the sum of the volume of each part, like this:

[tex]\begin{gathered} V=V_t+V_c+V_s \\ r=\frac{d}{2}=\frac{2.6}{2}=1.3 \\ V_t=A_b\cdot\frac{h}{3}=\pi\cdot(r)^2\cdot\frac{h}{3}=3.14\cdot(1.3)^2\cdot\frac{1.2}{3}=2.12cm^3 \\ V_c=A_b\cdot h=\pi\cdot(r)^2\cdot h=3.14\cdot(1.3)^2\cdot1.8=9.55m^3 \\ V_s=\frac{4}{6}\cdot\pi\cdot r^3=\frac{4}{6}\cdot3.14\cdot(1.3)^3=4.6cm^3 \\ V=V_t+V_c+V_s \\ V=2.12+9.55+4.6 \\ V=16.27cm^3 \end{gathered}[/tex]

The volume of the upper container is 16.27 cm^3, and being symmetrical, it is the same for the bottom container.

At the moment that all the sand finishes going to the bottom container, the height will be the sum of the heights in each case.

Then:

[tex]\begin{gathered} h=1.2+1.8+1.3 \\ h=4.3\text{ cm} \end{gathered}[/tex]

Therefore, the height is 4.3 centimeters

To reach that height, all the sand had to be passed from one side to the other, therefore, we can calculate the time as follows:

[tex]\begin{gathered} t=\frac{16.27cm^3}{0.05\frac{cm^3}{s}} \\ t=325.4\text{ sec} \end{gathered}[/tex]

It would take a time of 325.4 seconds

QuestionA cylinder has height 6 meters and radius 5 meters. Find the a. volume and b. surface area. Use 3.14 for. Do not round.

Answers

Problem: A cylinder has a height 6 meters and a radius 5 meters. Find the a. volume and b. surface area. Use 3.14 for. Do not round.

Solution:

Remember that the volution of cylinder is given by the following equation:

[tex]V\text{ =}\pi\text{r}^2h[/tex]

where r is the radius of the cylinder and h is the height of the cylinder. In this case, we have that:

[tex]V\text{ =}\pi\text{r}^2h=\pi5^2\text{ x 6 = 150}\pi\text{ = 471.23}[/tex]

So we can conclude that the volume of the cylinder is 471.23

Now, for surface area, remember that the surface area for the cylinder is given by the following equation:

[tex]V=2\pi r^2+\text{ }2\pi rh[/tex]

where r is the radius of the cylinder and h is the height of the cylinder. In this case, we have that:

[tex]V=2\pi r^2+\text{ }2\pi rh\text{ = 2}\pi(5)^2\text{ + 2}\pi(5)(6)\text{ = 110}\pi\text{ = 345.57}[/tex]

So we can conclude that the surface area for the cylinder is 345.57

suppose they are a T V cost in an election between three Canadians then who is Garza and we see to be decided by polarity of the first 55 votes are counted the Titleist are as followed

Answers

a) We have the votes for 55 people out of 80.

We have to find the minimum number of votes needed by Donahue to be sure that he will win the election.

There are 80 - 55 = 25 votes remaining.

Donahue has 24 votes already. The second candidate in number of votes has 18 votes, which is a difference of 6 votes.

We can think of a situation where the remaining votes are given to this two candidates and both have the same votes.

This would mean an amount of 24 + 18 + 25 = 67 votes.

Then, they won't have the same votes but we can think of Donahue having 67/2 = 33.5 ≈ 34 votes, and Garza having 33.

Then, this is the most extreme situation where Donahue wins by one vote.

We can then calculate the difference of votes he needs as 34 - 24 = 10 votes.

b) We can think again the same situation, but with Garza having 34 votes and Donahue having 33 votes.

This the extreme situation where Garza wins by the minimum difference.

Then, Garza would have to add 34 - 18 = 16 votes at least to win in this situation.

Answer:

a) Donahue needs 10 more votes to be sure he wins the election.

b) Garza needs at least 16 votes to be sure he wins the election.

Hello! I got -560 just want to confirm my answer. Thanks!

Answers

Explanation

We are given the following series:

[tex]12+4-4-12-20-...[/tex]

We are required to determine the sum of the first 14 terms of the given series.

This is achieved thus:

We know that the sum of n terms of a series is given as:

[tex]\begin{gathered} S_n=\frac{n}{2}[2a+(n-1)d] \\ where \\ a=first\text{ term} \\ d=common\text{ difference} \\ n=number\text{ of terms} \end{gathered}[/tex]

Therefore, we have:

[tex]\begin{gathered} S_n=\frac{n}{2}[2a+(n-1)d] \\ where \\ a=12 \\ d=4-12=-8 \\ n=14 \\ \\ \therefore S_{14}=\frac{14}{2}[2\cdot12+(14-1)-8] \\ S_{14}=7[24+(13)-8] \\ S_{14}=7(24-104) \\ S_{14}=7\cdot-80 \\ S_{14}=-560 \end{gathered}[/tex]

Hence, the answer is:

[tex]S_{14}=-560[/tex]

Prepare an amortization schedule for the first three months on a loan of $87000 at 6% for 20 years

Answers

First, we need to calculate the value of the monthly payments. We can use the general ordinary anuity formula:

[tex]PV=\text{PMT}\cdot\lbrack\frac{1-(1+i)^{-n}}{i}\rbrack[/tex]

Where PV=$87000

n=20

i=0.06

Replace the given values and solve for PMT:

[tex]\begin{gathered} 87000=\text{PMT}\cdot\lbrack\frac{1-(1+0.06)^{-20}}{0.06}\rbrack \\ 87000=\text{PMT}\cdot\lbrack\frac{1-0.3118}{0.06}\rbrack \\ 87000=\text{PMT}\cdot\lbrack\frac{0.6882}{0.06}\rbrack \\ 87000=\text{PMT}\cdot11.4699 \\ \text{PMT}=\frac{87000}{11.4699} \\ \text{PMT}=7585.06 \end{gathered}[/tex]

Now that you have the payment, you can construct the table of the amortization schedule with the know information:

To calculate the missing information, start by calculating the interest component of the payment (interest paid) by multiplying the periodic interest by the remaining principal.

The monthly interest is the yearly interest divided by 12, then:

[tex]MI=\frac{0.06}{12}=0.005[/tex]

And the interest paid is then:

[tex]\begin{gathered} IP=MI\cdot\text{ Remaining principal} \\ IP=0.005\cdot87000\text{ (for the first payment)} \\ IP=435 \end{gathered}[/tex]

Now, calculate the principal paid by subtracting the interest paid from the payment amount:

[tex]\text{ Principal paid=7585.06-435}=7150.06\text{ (first payment)}[/tex]

Then, by putting the values on the amortization schedule:

The remaining principal is 87000-7150.06 (principal paid).

Now for the second payment, calculate the interest paid with the new remaining principal:

[tex]\begin{gathered} IP=0.005\cdot79849,94\text{ (for the second payment)} \\ IP=399,25 \end{gathered}[/tex]

And the principal paid is:

[tex]\text{ Principal paid=7585.06-399.25}=7185.81\text{ (second payment)}[/tex]

The remaining principal is:

[tex]RP=79849.94-7185.81=72664.13[/tex]

Thus:

And for the third month, you apply the same calculations and the amortization schedule is:

John was asked to place the numbers shown below in order from greatest to least. 0.2 , -0.3, 1.6, 120%, -2%, 3.8, --33, 3.14 After ordering the numbers from greatest to least, what number would John have in the 3rd position?

Answers

Let's begin by listing out the information given to us:

0.2, -0.3, 1.6%, 120%, -2%, 3.8, -33, 3.14

In sorting the numbers from the greatest to the least, we must bear the following in mind:

I. Any number having a negative parenthesis is lower than zero

II. % means 100; any number having % means the real value of the number is multiplied by 100

0.2 = 0.2

-0.3 = -0.3

1.6% = 1.6 * 100 = 160

120% = 120 * 100 = 12000

-2% = -2 * 100 = -200

3.8 = 3.8

-33 = -33

3.14 = 3.14

Rearranging from the greatest to the least, we have it thus:

120%, 1.6%, 3.8, 3.14, 0.2, -0.3, -33, -200

The number in the third position is 3.8

PR = 9x -31 and QR = 43: Find xQ is the midpoint of PR

Answers

We can model the situation as:

Since Q is the midpoint of PR, QR and PQ have the same length, so PQ is also equal to 43.

Now, we can formulate the following equation:

PR = PQ + QR

So, replacing PR by 9x-31, PQ by 43 and QR by 43, we get:

9x - 31 = 43 + 43

9x - 31 = 86

Solving for x:

9x - 31 + 31 = 86 + 31

9x = 117

9x/9 = 117/9

x = 13

Answer: x = 13

I need help with a graph problem please that I am stuck on.

Answers

Solution:

First we have to derive the equation of the graph plot.

The general equation of an absolute value function is expressed as

[tex]\begin{gathered} y=a|x-h|+k\text{ --- equation 1} \\ \text{where} \\ (h,k)\text{ is the coordinate of the vertex of the function } \end{gathered}[/tex]

step 1: Determine the coordinates (h,k) of the vertex of the graph.

The vertex of the function is the point at which the graph changes direction.

In tha above plot, the vertex of the plot is (-3,4).

Thus,

[tex]\begin{gathered} h=-3 \\ k=4 \end{gathered}[/tex]

step 2: Substitute the respective values of -3 and 4 for h and k into equation 1.

Thus,

[tex]\begin{gathered} y=a|x-h|+k \\ \Rightarrow y=a|x-(-3)|+4\text{ ---- equation 2} \\ \end{gathered}[/tex]

step 3: Select any point (x,y) on the graph plot, to evaluate a.

Thus, using the point (1,0), we have

[tex]\begin{gathered} y=a|x+3|+4 \\ x=1,\text{ y=0} \\ \Rightarrow0=a|1+3|+4 \\ -4=|4|a \\ \Rightarrow a=-1 \end{gathered}[/tex]

step 4: Substitute the obatined value of a into equation 2.

Thus,

[tex]y=-|x+3|+4\text{ ----- equation 3}[/tex]

Thus, the equatioin of the graph is evaluated to be

[tex]y=-|x+3|+4[/tex]

A) Evaluate f(4).

To evaluate f(4), substitute the value of 4 for x into the derived equation.

Thus,

[tex]\begin{gathered} y=-|x+3|+4 \\ x=4 \\ \Rightarrow y=-|4+3|+4 \\ \therefore y=-3 \end{gathered}[/tex][tex]f(4)=-3[/tex]

B) Solve for f(x)=2.

To solve, we have

[tex]\begin{gathered} -|x+3|+4=2 \\ \text{subtract 4 from both sides of the equation} \\ -|x+3|+4-4=2-4 \\ -|x+3|=-2 \\ \text{divide both sides by -1} \\ \frac{-|x+3|}{-1}=-\frac{2}{-1} \\ \Rightarrow|x+3|=2 \\ \text{When }x+3=-2 \\ x=-2-3 \\ \Rightarrow x=-5 \\ \text{when }x+3=2 \\ x=2-3 \\ \Rightarrow x=-1 \end{gathered}[/tex]

Thus, we have

Round the answer to the nearest tenth of a therm (one decimal place). Only input the number. Do not input any unit. Example: 89.3

Answers

Kauro, this is the solution:

This is the cost function for natural gas for the city where Greg lives:

• c (t) = 16.74 + 0.742t

Now we replace c (t) by 51.54 to solve for t, as follows:

51.54 = 16.74 + 0.742t

Subtracting 16.74 at both sides:

51.54 - 16.74 = 16.74 + 0.742t - 16.74

34.8 = 0.742t

Dividing by 0.742 at both sides:

0.742t/0.742 = 34.8/0.742

t = 46.9 therms

The correct answer is 46.9

[tex]\begin{gathered} \text{area = base}\times\text{height} \\ 12=9\times h \\ Divide\text{ both sides by 9.} \\ \frac{12}{9}=\frac{9h}{9} \\ \frac{4}{3}or\text{ 1.33 = h} \end{gathered}[/tex]

Therefore, the height of the parallelogram is 4/3 or 1.33 units.

the quotient rule say:

[tex](\frac{f(x)}{g(x)})^{\prime}=\frac{g(x)\cdot f^{\prime}(x)-f(x)\cdot g^{\prime}(x)}{(g(x))^2}[/tex]

now we defined:

[tex]\begin{gathered} f(x)=-4x^2+16 \\ g(x)=(x^2+4)^2 \end{gathered}[/tex]

and the derivative:

[tex]\begin{gathered} f^{\prime}(x)=-8x \\ g^{\prime}(x)=2\cdot(x^2+4)\cdot2x \\ g^{\prime}(x)=4x(x^2+4) \end{gathered}[/tex]

so now we can replace on the quotient rule:

[tex]\frac{(x^2+4)^2\cdot(-8x)-4x(x^2+4)\cdot(-4x^2+16)}{(x^2+4)^4}[/tex]

now we can use properties, like:

[tex](x^2+4)^2=x^4+8x+16[/tex]

The shaded area is 120T cm?, and the radius is 24 cm. Find X.

Answers

We will have the following:

[tex]A=(\frac{x}{2})\cdot r^2\Rightarrow120\pi=(\frac{x}{2})(24)^2[/tex][tex]\Rightarrow\frac{x}{2}=\frac{5\pi}{24}\Rightarrow x=\frac{5\pi}{12}[/tex][tex]\Rightarrow x\approx1.31[/tex]

So, the value of x is approximately 1.31.
