Answer:

1. 108.375 2. 76.765625

Step-by-step explanation:

1. We have the s-value now, which is 4.25.

Plug it in to the equation for surface area:

6*(4.25)^2

6*4.25*4.25

Using a calculator, we get 108.375

2. Plug 4.25 in to the equation for volume:

(4.25)^3

4.25*4.25*4.25

Using a calculator, we get 76.765625

I kinda sorta understand this but not completely
Greeley [361]
Problems 1 - 8.
When you multiply the same number raised to exponents, add the exponents. When you divide the same number raised to exponents, subtract the exponents.

1. 7^{-5} \cdot 7^{3} = 7^{-5 + 3} = 7^{-2}

3. \dfrac{2^{7}}{2^{10}} = 2^{7 - 10} = 2^{-3}

Can someone tell me the answer step by step about the surface area please I hope some one can answer me
Bas_tet [7]
1.) Find the width and length.
- Width is how wide it is
- Length is how long it is

2.) In this case, the width is 14, while the length is 3.

3.) Multiply those to find your surface area. ( 14 x 3 = 42 )

4.) 42 is your surface area, but AREA is always SQUARED ( small 2 on the top right of the number )

5.) Final answer will also have to be labeled. In this case, it is using in (Inches).

6.) 42 inches squared is your final answer.

A magazine has a special offer of 18 issues for $28.44. How much does each issue cost?
Angelina_Jolie [31]
An expression you could use to solve this is 18x = 28.44 where x = the cost of the magazine.

18x = 28.44

Divide 18 from both sides.

x = 1.58

Each issue costs $1.58

Hope this helps!

What is the value of r if the line that passes through ( 4,3 ) and ( -5,r ) has a slope of -1
Wewaii [24]

Answer:

r= 12

Step-by-step explanation:

Slope= \frac{y1 - y2}{x1 - x2}

Using the formula above,

\frac{r - 3}{ - 5 - 4}  =  - 1 \\   \frac{r - 3}{ - 9}  =  - 1 \\ r - 3 =  - 1( - 9) \\ r - 3 = 9 \\ r = 9 + 3 \\ r = 12
