What is the volume of this sphere? Use : 3.14 and round your answer to the nearest hundredth. 10 yd cubic yards
Margarita [4]

EXPLANATION

The volume of a sphere is given by the following relationship:

\text{Volume}=\frac{4}{3}\cdot\pi\cdot(r)^3

Replacing terms:

\text{Volume = }\frac{4}{3}\cdot\pi\cdot(10)^3\text{Volume = }\frac{4}{3}\cdot3.14\cdot1000

Multiplying numbers:

\text{Volume = 4186.67 yd}^3

The answer is 4,186.67 yd^3

A student says that the solution of 375=x-28 is 347. Explain the student's error and find the correct answer.
Genrish500 [490]

Hi there!

Answer:

<u><em>x=403 and 403=x</em></u>

Step-by-step explanation:

Because a student says the answer is 347 is not the right answer. The final answer should be x=403 and 403=x.

375=x-28

Switch sides.

x-28=375

add by 28 both sides of an equation.

x-28+28=375+28

simplify.

x=403 and 403=x

403-28=375

28+375=403

Hope this helps!

2√6 ∙ √8 + 2√12<br><br>show your work please and thank you
meriva

Answer:

Step-by-step explanation:

multiply first,

so 2√6 x √8 = 2√48 (because when radicals are multiplied we add them)

so

2√48 can be simplified to 8√3 and 2√12 can be simplified to 4√3

8√3+4√3=12√3

Z−4/9−1/3=5/9 Enter your answer as a fraction in simplest form in the box. z =
aleksklad [387]

Answer:

z = 4/3 or 1 1/3

Step-by-step explanation:

z−4/9−1/3=5/9

Change 1/3 to have a denominator of 9

1/3 *3/3 = 3/9

z−4/9−3/9=5/9

Combine like terms

z -7/9 = 5/9

Add 7/9 to each side

z-7/9+7/9 = 5/9+7/9

z = 12/9

z=4/3

or as a mixed number

z = 1 1/3
