GUYS QUICK! what is the surface area of a sphere that has a radius of 5 cm

alisha [4.7K]

Answer:

100 pi cm^2

or approximately 314 cm^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 5

SA = 4 *pi * 5^2

SA = 4*pi(25

SA = 100 pi cm^2

If pi is 3.14

SA = 100 *3.14 = 314 cm^2

I know its hard to see, but if you can see it, can you plz help me with #59. Thnks.

Gnoma [55]

C

A slope of $\frac{4}{3} 

$ means that for every time x goes up by 3, y goes up by 4.

28 - 22 = 6 which is 2 times 3.
while 10-2 = 8 which is 2 times 4.

This fits the slope.

Joes age (j) is half Martha’s (m). Combined, their age is 42. What are their ages?

svp [43]

Answer:

Joe is 14.

Martha is 28.

Step-by-step explanation:

Use the variables and information from the question to make equations.

If Joe's age is half Martha's:

(1/2)m = j OR 2j = m

If their ages combined is 42:

m + j = 42

We can substitute the equation m=2j into equation m + j = 42, replacing "m".

m + j = 42 Substitute m for 2j

2j + j = 42 Combine like terms, terms with same varables

3j = 42 Divide both sides by 3 to isolate j

j = 14 Joe's age

Since j = 14, we can substitute it into equation m=2j to find "m".

m = 2j Substitute j for 14

m = 2(14) Simplify

m = 28 Martha's age

Therefore Joe is 14 and Martha is 28.

20 - 7x = 7x + 13 solution or no solution

Alekssandra [29.7K]

Hi,

Solving:

$20 - 7x = 7x + 13 \\ - 7x - 7x + 20 = 7x - 7x + 13 \\ - 7x - 7x + 20 = 13 \\ - 7x - 7x = 13 - 20 \\ ( - 7 - 7)x = - 14x \\ - 14x = 13 - 20 \\ - (20 - 13) = - 7 \\ - \not14x \div ( - \not14) = - 7 \div ( - 14) \\ x = -7 \div ( - 14) \\ ( - ) \div ( - ) = ( + ) \: \: \: \: \: \: \: rule \\ x = 7 \div 14 = \frac{1}{2} = 0.5$

Equation haves a solution.
