The simple interest charged by the lender on Alonzo is $ 126 and the amount paid after 6 years is $ 826.
Principal amount of loan = $ 700
Time period = 6 years
Interest rate = 3 %
The simple interest is charged by the lender:
The interest will be:
SI = p × r × t / 100
Substitute the values, we get that:
SI = 700 × 3 × 6 / 100
SI = 7 × 3 × 6
SI = $ 126
The amount paid by Alonzo after 6 years will be:
Amount = $ 700 + $ 126
A = $ 826
Therefore, the simple interest charged by the lender on Alonzo is $ 126 and the amount paid after 6 years is $ 826.

QRS and SRT are complementary. if m QRS (8x+10)° and m SRT=(8x)°Determine m QRSm QRS=
We are given two complementary angles (QRS and SRT).
Two angles are called complementry if they sum up to 90 degrees.
Therefore, by defination
mQRS + mSRT = 90
(8x+10) + (8x) = 90
8x + 8x + 10 = 90
16x = 90-10
16x = 80
x = 80/16
x = 5
Now, put the values in both the euqations and we will get the values of both the angles.
mQRS = 8x + 10 = 8(5) + 10 = 40 + 10 = 50 degrees
mSRT = 8x = 8(5) = 40 degrees

Why is the quotient of three divided by one-fifth different from the quotient of one-fifth divided by three? Hello my child needs help with this question could someone help
Solution
We want to get why
[tex]\frac{3}{\text{ \lparen1/5\rparen}}\text{ is different from }\frac{\text{ \lparen1/5\rparen}}{3}[/tex]Reason 1: Commutation Law Does Not Hold For Division (or quotient)
Generally,
[tex]\frac{a}{b}\ne\frac{b}{a}[/tex]Reason 2: Actual Computation
First
[tex]\begin{gathered} \frac{3}{\text{ \lparen1/5\rparen}}=3\div\frac{1}{5} \\ \\ \frac{3}{\text{ \lparen1/5\rparen}}=3\times\frac{5}{1} \\ \\ \frac{3}{\text{ \lparen1/5\rparen}}=15 \end{gathered}[/tex]Secondly
[tex]\begin{gathered} \frac{\text{ \lparen1/5\rparen}}{3}=\frac{1}{5}\div3 \\ \\ \frac{\text{ \lparen1/5\rparen}}{3}=\frac{1}{5}\times\frac{1}{3} \\ \\ \frac{\text{ \lparen1/5\rparen}}{3}=\frac{1}{15} \end{gathered}[/tex]It is now obvious that
[tex]\frac{3}{\text{ \lparen1/5\rparen}}\ne\frac{\text{ \lparen1/5\rparen}}{3}[/tex]4(b-1)= -4+4b what is the solution
Starting with the equation:
[tex]4(b-1)=-4+4b[/tex]Use the distributive property to expand the parenthesis in the left hand side of the equation:
[tex]4b-4=-4+4b[/tex]Use the commutative property to rewrite the right hand side of the equation, swapping the terms:
[tex]4b-4=4b-4[/tex]Since both sides of the equation are the same, any value of b is a solution to the equation.
Therefore, all numbers are a solution for the equation 4(b-1)=-4+4b.

c. Either a or b must be negative.
d. The quotient -a + b is negative.
Deciding if each statement about a and b is true or false.
a)False
b)True
c)True
d)False
Given:
The quotient of a and b is negative.
a.
If quotient is negative means the dividend or divisor any one is negative so when the quotient b+a is always negative so given statement is false.
b.
The product ab is always negative because if the quotient is negative means either a or b is negative so ab is negative.
So given statement is true.
c.
Either a or b must be negative is true because if no element a or b is not negative we cannot produce a negative quotient hence either a or b must be negative.
d.
The quotient -a+b is negative is false because if the quotient is negative the values of a and b is one positive and one negative the positive number that is b greater than -a in that case the statement is false.

what are the coordinates of the point on the directed line segment from (2,-1) to (9,6) that partitions the segment into a ratio of 5 to 2
Ok, so:
Let x and y be coordinate of the point C that partitions the segment.
And Let A = ( 2, -1 ) and B = ( 9 , 6 ).
So, given that C partitions the segment into a ratio of 5 to 2, we have:
Total parts of the segment: 5+2 = 7.
So, the point C is 5/7 of way from A to B.
Let me draw the situation:
Now, we know that the right distance is 7 and the upper distance is 7.
Now we multiply 5/7 per both distances.
5/7 * 7 = 5
5/7 * 7= 5
Now, we take the initial point A ( 2, -1 ), and sum 5 to each coordinate.
Then, the point C = ( 7 , 4 )

In 1994, the moose population in a park was measured to be 4930. By 1999, the population was measured again to be 6180. If the population continues to change linearly: A.) Find a formula for the moose population, P, in terms of t, the years since 1990. P(t) B.) What does your model predict the moose population to be in 2006?
We define the following variables for our problem:
P = population of mooses
t = number of years since 1990
m = growth ratio
In terms of the variables that we defined above and the fact that the population of moose in terms of the year is linear, we have the following equation:
[tex]P(t)=m\cdot t+P_0[/tex]Now, we use the data of the problem:
1) In 1994 the moose population was 4930, so we have:
[tex]\begin{gathered} t=1994-1990=4 \\ P(4)=4930 \end{gathered}[/tex]2) In 1999 the moose population was 6180, so we have:
[tex]\begin{gathered} t=1999-1990=9 \\ P(9)=6180 \end{gathered}[/tex]Now, using the data above and the equation for P(t) we construct the following system of equations:
[tex]\begin{gathered} P(4)=m\cdot4+P_0=4930 \\ P(9)=m\cdot9+P_0=6180 \end{gathered}[/tex]We solve the system of equations.
First, we solve the equations for P0:
[tex]\begin{gathered} P_0=4930-4m \\ P_0=6180-9m \end{gathered}[/tex]Now, because the right-hand-side of both equations is equal to P0, we equal them and then we solve for the variable m:
[tex]\begin{gathered} 4930-4m=6180-9m \\ 9m-4m=6180-4930 \\ 5m=1250 \\ m=250 \end{gathered}[/tex]Finally, we replace the value of m in one of the equations of P0 and solve for it:
[tex]\begin{gathered} P_0=4930-4\cdot m \\ P_0=4930-4\cdot250 \\ P_0=3930 \end{gathered}[/tex]A) The formula for the moose population, P, in terms of t, the years since 1990 is:
[tex]P(t)=250t+3930[/tex]B) We want to know the value of the moose population in 2006.
First, we compute the value of t:
[tex]t=2006-1990=16[/tex]Now, we replace the value of t in the equation of P(t) above:
[tex]P(6)=250\cdot16+3930=7930[/tex]Answer: 7930

You need to add 10 ounces of 20% alcohol solution.
x = ounces of 20% alcohol solution to add to the 15 oz of 25% solution
15 oz of a 25% solution = 3.75 oz of pure alcohol
The total amount can be described 15+x ounces.
We solve the problem in terms of the amount of pure alcohol
2x + 3.75 = .23(15+x)
2x + 3.75 = 3.45 + .23x
Subtracting .2x from both sides
3.75 = .03x + 3.45
Subtracting 3.45 from both sides
3 = .03x
Multiply by 100
30 = 3x
Divide by 3
10 = x
x = 10
So, you have to add 10 oz of 20% alcohol solution to 15 oz of 25% alcohol.
At the end we would have 25 oz that we believe would be 23% alcohol. If that is true, then we would have:
23 * 25 = 5.75 oz of pure alcohol in the solution.
We have shown (above) that we have 3.75 oz of pure alcohol in the 15 oz of 25% solution.
How many oz of pure alcohol is there in 10 oz of 20% alcohol?
2*10 = 2 oz
3.75 + 2 = 5.75 oz, which is exactly what we needed
