Write a system of equations to describe the situation below, solve using an augmented matrix.The glee club needs to raise money for the spring trip to Europe, so the members are assembling holiday wreaths to sell. Before lunch, they assembled 20 regular wreaths and 16 deluxe wreaths, which used a total of 140 pinecones. After lunch, they assembled 20 regular wreaths and 18 deluxe wreaths, using a total of 150 pinecones. How many pinecones are they putting on each wreath?The regular wreaths each have ? pinecones on them and the large ones each have ? pinecones.

Answers

Answer 1

Given

First : They assembled 20 regular wreaths and 16 deluxe wreaths, which used a total of 140 pinecones

Let's represent regular wreaths with r

and

Let's represent deluxe wreaths with d

[tex]20r+16d=140[/tex]

Second: They assembled 20 regular wreaths and 18 deluxe wreaths, using a total of 150 pinecones

[tex]20r+18d=150[/tex]

We now have

[tex]\begin{gathered} 20r+16d=140\text{ ...Equation 1} \\ 20r+18d=150\text{ ...Equation 2} \end{gathered}[/tex]

we can now solve simultaneously, by subtracting the equation 1 and 2

[tex]\begin{gathered} 20r-20r+16d-18d=140-150 \\ -2d=-10 \\ Divide\text{ both sides by -2} \\ -\frac{2d}{-2}=-\frac{10}{-2} \\ \\ d=5 \end{gathered}[/tex]

We can subsitute d=5 in equation 1 or 2

[tex]\begin{gathered} 20r+16d=140\text{ ... Equation 1} \\ 20r+16(5)=140 \\ 20r+80=140 \\ 20r=140-80 \\ 20r=60 \\ divide\text{ both sides by 20} \\ \frac{20r}{20}=\frac{60}{20} \\ \\ r=3 \end{gathered}[/tex]

The final answer

5 pinecones on the deluxe wreath and 3 pinecones on the regular wreath

Find the amount of each payment R for a t= 18 year loan with principal P = $18,000 and interest rate r = 9% compounded monthly. Round your final answer to two decimal places.

Answers

The amount of each payment to 2 decimal places = $90406.80

Explanation:

t = 18 year

Principal = P = $18,000

r = 9% 0.09

Using compound interest formula:

[tex]FV\text{ = P(1 + }\frac{r}{n})^{nt}[/tex]

n = number of times it was compounded in a year.

since it is monthly, n = 12

[tex]\begin{gathered} FV\text{ =future value} \\ FV\text{ = 18000(1+ }\frac{0.09}{12})^{12\times18} \end{gathered}[/tex][tex]\begin{gathered} FV=18000(1+0.0075)^{216} \\ FV\text{ = }18000(1.0075)^{216} \\ FV\text{ = 18000}\times5.0226 \\ FV\text{ = 90406.8} \end{gathered}[/tex]

Last year, Milan had $10,000 to invest. He invested some of it in an account that paid 6% simple interests per year, and he invested the rest in an account that paid 9% simple interest per year. After one year, he received a total of $840 in interest. How much did he invest in each account?

Answers

Let's define the next variables

x: amount of money invested in one account

y: amount of money invested in the other account

Milan had $10,000 to invest, then

x + y = 10000 (eq. 1)

The interest Milan gets after one year are: 0.06x and 0.09y. He received a total of $840 in interest, then

0.06x + 0.09y = 840 (eq. 2)

Isolating x from equation 1:

x = 10000 - y

Replacing this result into equation 2,

0.06(10000 - y) + 0.09y = 840

0.06(10000) - 0.06(y) + 0.09y = 840

600 + 0.03y = 840

0.03y = 840 -600

0.03y = 240

y = 240/0.03

y = 8000

Then,

x = 10000 - y

x = 10000 - 8000

x = 2000

He invested $2000 in the account that paid 6% simple interests per year and $8000 in the account that paid 9% simple interests per year

a certain number is n

Put this together in an equation

5/100n = -62/3

Divide both sides by 5/100 to solve for n

When we divide fractions we flip the divisor and multiply

-62/3 ÷ 5/100

-62/3 x 100/5

-6200/15 = -413 5/15 simplified to -413 1/4

The number is -413 1/3

Answers

1) The first thing we need to do in this question, is to find the sample space, i.e. the total number of outcomes, in this case, fishes.

[tex]262+382+181+336+190=1351[/tex]

2) Since no one could pick simultaneously two types of fish, then we can tell that these events are mutually exclusive. So, we can write the following:

[tex]\begin{gathered} P(flounder)=\frac{262}{1351} \\ \\ P(black\:drum)=\frac{181}{1351} \\ \\ P(red\:drum)=\frac{382}{1351} \\ \\ P(drum\:or\:flounder)=\frac{262}{1351}+\frac{181}{1351}+\frac{382}{1351}=\frac{825}{1351}\approx0.6107 \end{gathered}[/tex]

Note that by "drum" we are including black and red drum.

The size, x, in an automobile tire can affect its performance. Both over-sized and under-sized tires can lead to poor performance and poor mileage. The tire size that yields the best performance for the car Michael wants is given by 0.2(x - 25.5) + 0.3 = - 0.2(x - 16).Find the tire size that will yield the best performance for Michael’s car.

Answers

The tire size that will yield the best performance for Michael’s car is 20.

The equation given is,

0.2(x - 25.5) + 0.3 = - 0.2(x - 16)

From this, we have to solve for x, which will give the size of the tire.

Simplify the equation as follows to find x,

0.2(x - 25.5) + 0.2(x - 16) = - 0.3

0.2x - (0.2 × 25.5) + 0.2x - (0.2 × 16) = - 0.3

0.2x - 5.1 + 0.2x - 3.2 = - 0.3

0.4x - 8.3 = - 0.3

0.4x = - 0.3 + 8.3

0.4x = 8

x = 8/0.4 = 20.

Increasing the wheel diameter also increases the final deceleration which has two consequences. Acceleration potential is reduced but a higher final speed is achieved. In other words, the bigger the car's tires the slower it accelerates but the higher its top speed.

We recommend choosing smaller wheels for more power and as many times as possible for maximum traction. On average, a 15 x 3.75 or larger front wheel gives the best results. For the rear, a 15 x 10 wheelset is ideal.

In linear equation, Equation for line F is y = 1.75x + 3.5 and equation for line G is y = -4x-8.

What is a linear equation example?

Ax+By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x+3y=5.Finding both intercepts of an equation in this format is rather simple (x and y).

y = 1.75x + 3.5   (For line F)

let's take the point (2,7) and put in the equation,

y = 1.75*2 + 3.5

 = 3.5 +0.35

 = 7

which is true.

Hence, (2,7) satisfies the equation.

y = -4x-8   (For line G)

lets take the point (-3,4) and put in the equation,

y = (-4)*(3) - 8

 = 12 - 8

 = 4

which is true.

Hence, (-3,4) satisfies the equation.
