What is 7/8 times c for c=8

2 answers:

4 0

Just plug n chug, if c=8.

7/8*c

turns into 7/8*8/1.

Cross cancel the 8's. They turn into 1's.

Thus. 7/1*1/1=7

7 is your answer.

First you do seven (7) divided (/) by eight (8). Then substitute c for 8.
7/8=<span>0.875
0.875(8)=7

Your answer is 7.</span>

The perimeter is the sum of all of the sides.

3x + 2 + x + 13 + 3x + 8 + 2 + x + 5

Combine like terms:

8x + 30

So the perimeter is 8x + 30

Cynthia has the choice of taking out a 25-year loan for $155,000 at 4.4%

ser-zykov [4K]

Answer:

D. Less than $100,831

Step-by-step explanation:

There is an equation for calculating monthly payment:

x = p • r • (1+r)^n / (1+r)^n - 1

It may seem a bit complicated, but let's explain it step by step:

- p is the amount of loan, in this case $155,000

- r is monthly interest rate, in this case (4.4/12) / 100, which is 0.00367

- n is the number of months for paying back, or in this case 20 • 12 = 240

Now that we know all the values, all that's left is to plug them in and solve it on the calculator:

x = 155,000 • 0.00367 • (1.00367^240) / (1.00367^240) - 1

x = $972.27

So, the monthly payment is around $972.3. We now multiply it by the number of months to get total payment:

$973.3 • 240 = $233,352

So, the total amount, loan plus interest, is 233,352 dollars.

To only find amount of interest, we simply subtract loan from total amount:

$233,352 - $155,000 = $78,352

The radius of a cylinder gift box is box is 3X +1 inches the height of the gift box is twice the radius what is the surface area

Genrish500 [490]

Answer:

The surface area of the gift box is = $A = \frac{1188}{7}x^{2}+ \frac{774}{7}x +\frac{132}{7}$

Step-by-step explanation:

The surface area of the cylinder can be calculated using this formula:

$A=2\pi rh+2\pi r^2$

in this case, r is not a number, but rather an expression, which is r = $3x +1$ .

The height of the gift box is twice the radius, which is h = $2(3x+1)= 6x+2$

To get our curved surface area, we carefully put the expressions for h and r into the equation.

$A = 2 \times \frac{22}{7} \times (3x+1) \times (6x+2) + 2 \times \frac{22}{7} \times (3x+1)^{2}$

$A = \frac{44}{7} (3x+1) \times (6x +2) + \frac{44}{7} (9x^{2} + 6x +1)\\A =\frac{132}{7}x + \frac{44}{7} \times (6x+2)+ \frac{396}{7}x^{2}+\frac{246}{7}x +\frac{44}{7}$

$A = \frac{792}{7}x^{2} +\frac{264}{7}x +\frac{264}{7}x + \frac{88}{7} + \frac{396}{7}x^{2} + \frac{246}{7}x + \frac{44}{7}$

$A = \frac{1188}{7}x^{2}+ \frac{774}{7}x +\frac{132}{7}$

The surface area of the gift box is = $A = \frac{1188}{7}x^{2}+ \frac{774}{7}x +\frac{132}{7}$
