Answer:

The number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Step-by-step explanation:

It is important to note that:

A quarter is worth 25 cents = 0.25q

A nickel is worth 5 cents = 0.05n

George has only Quarters and nickels in his piggy bank.

Let the number of

Quarters = q

Nickels = n

He has a total of 90 coins.

Hence,

q + n = 90.... Equation 1

q = 90 - n

The value of the coins is $16.10.

Hence,

0.25q + 0.05n = 16.10....Equation 2

We substitute 90 - n for q in Equation 2

0.25(90 - n) + 0.05n = 16.10

22.5 - 0.25n + 0.05n = 16.10

Collect like terms

- 0.25n + 0.05n = 16.10 - 22.5

-0.2n = - 6.4

n = -6.4/-0.2

n = 32 nickels

Solving for q

q = 90 - n

q = 90 - 32

q = 58 quarters

Therefore, the number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

I don't really understand this question

But if it's asking you to switch,

1. r = 2.5

2. r = 12

3. d = 34

Answer:

a(n) = 4*(2)^(n - 1)

Step-by-step explanation:

The correct version of this formula is a(n) = a(1)*r^(n - 1).  Must use the " ^ " symbol to indicate exponentiation, and enclose the "n - 1" inside parentheses.

Here, if 4, 8, 16, 32, ..., then a(1) = 4 and r = 2 (e. g., 16/8 = 2, 32/2 = 16, and so on).

Then the correct formula for this geometric sequence is

a(n) = 4*(2)^(n - 1), where use of the parentheses as indicated is mandatory.

Answer:

y = 170 - 3x

Step-by-step explanation:

l // m

y + 3x + 10 = 180  {co interior angles are supplementary}

 y + 3x   = 180 - 10   {Subtract 10 from both sides}

   y+ 3x = 170      {Subtract 3x from both sides}

          y = 170 - 3x

Answer:

m = 3, c = 0

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x , or y = 3x + 0 ← is in slope- intercept form

with m = 3 and c = 0

Answer:

k = -10.5

Step-by-step explanation:

k + 7.5 = -13

Subtract 7.5 from both sides

k + 7.5 - 7.5 = -13 - 7.5

            k = -20.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we multiply x - 7 by x - 3, we get x^2 - 10x + 21.  This shows that the LCD is x^2 - 10x + 21, or (x - 7)(x - 3).  Let's convert each of the two fractions on the right to their equivalents, with the LCD in the denominator.

Multiplying both the numerator and the denominator of 6/(x - 7) by (x - 3), we get 6(x - 3) over x^2 - 10x + 21, which is the LCD.

Similarly, we get 5(x - 7) over x^2 - 10x + 21.

Now all three of the original fractions have the same denominator, x^2 - 10x + 21.  We can now "drop" the LCD, which leaves us with:

x^2 - 29 = 6(x - 3) + 5(x - 7)  

Performing the indicated multiplications, we get:

x^2 - 29 = 6x - 18 + 5x - 35.  Combining like terms:

x^2 - 29 = 11x - 53, or x^2 - 11x + 24 = 0

This factors as follows:   x^2 - 11x + 24 = 0 = (x - 3)(X - 8) = 0

Then the preliminary solutions are x = 3 and x = 8.  Unfortunately, we cannot substitute x = 3 into the original equation, because that would lead to division by zero.  The only valid solution is x = 8, since every term of the original equation is defined at x = 8, and the equation is true for this value.

Repeat:  3 cannot be a solution because the 3rd fraction is undefined at

x = 3.  So we have only one valid solution (8) with no other solution to multiply by 8.

Answer: You may divide by a variable. But only if you know the variable is non-zero. So, if setting the variable to zero makes both sides of the equation zero, we have a solution that that variable is 0, or the equation with the variable divided out holds. E.g. solve x(x-1) = 0.

*see attachment for the diagram of the prisms

Answer:

Prism A

Step-by-step explanation:

✔️Volume of triangular prism (Prism A) = ½×bhl

b = 7 m

h = 9 m

l = 4 m

Volume of Prism A = ½ × 7 × 9 × 4

Volume of Prism A = 126 m³

✔️Volume of rectangular prism (Prism B) = L × W × H

L = 8 m

W = 2 m

H = 8 m

Volume of Prism B = 8 × 2 × 8 = 128 m³

✔️Prism A has the least volume

Answer:

Prism A has the least volume!

A and C are equivalent.

6d+6=2(3d+3)

6d+6=3d+3+3d+3=(3d+3)+(3d+3)

Answer:

A and C

Step-by-step explanation:

Given

4d + 6 + 2d ← collect like terms

= 6d + 6

Comparing the following

A

2(3d + 3) ← distribute parenthesis by 2

= 6d + 6

B

6(d + 6) ← distribute parenthesis by 6

= 6d + 36 ≠ 6d + 6

C

(3d + 3) + (3d + 3) ← remove parenthesis

= 3d + 3 + 3d + 3 ← collect like terms

= 6d + 6

Thus A and C are equivalent to the original expression

Answer:

problems 4,5,6,7  (make sure you add °C to the answers given in step one above)   *note, these answers given in both answers could be used for any of the deserts chosen, they all have the same formula given.

Step-by-step explanation:

4) box 12

(12,40)

f(12)= 9/5 (40)+ 32

f(12)= 72 +32

f(12)= 104 ° F

box 24

(24, -3.2)

f(24)= 9/5 (-3.2) +32

f(24) = -5.76 +32

f(24)= 26.24 °F

5.

substitute the given C(t) equation into the conversion formula

F(t)= 9/5C(t)+32.

We know from the information given that C(t)=−0.30(t−12)^2 +32

to solve:

F(t)= 9/5[−0.30(t−12)^2+40]+32

F(t)=1.8(−0.3t^2+7.2t−3.2)+32

F(t)=−0.54t^2+12.96t−5.76+32

F(t)=−0.54t^2+12.96t+26.24

It draw the lines to connect the bottom two points to 12, 104, It should look like  upside down V but curved softer like the graph in answer number 2.

7.  The changes made to the graph of C(t) to transform it to F(t) was changing the noon temperature (plot point) from 40° C to 104° F.  It increased the steepness of the graph.

Answer: $9.18

Step-by-step explanation:

The payment of $823.76 will go towards both interest and principal repayments.

Find out the interest paid from the amount and deduct it from the monthly payment to find the principal repayment.

Monthly interest payment:

= (85,000 * 11.5%) / 12 months

= $814.58

Principal repayment = 823.76 - 814.58

= $9.18
