Answer: On dividing 8.4 by 0.03 , we get 280.

Step-by-step explanation:

On dividing 8.4 by 0.03 , we get

8.4\div 0.03=\dfrac{8.4}{0.03}

Multiplying numerator and denominator by 100 , we get

\dfrac{8.4\times100}{ 0.03\times100}=\dfrac{840}{3}\\\\=280

Therefore , On dividing 8.4 by 0.03 , we get 280.

Thus , the answer is 280.

0.03 \sqrt{8.4}

you would need to make 0.03 a whole number 1st, so you take the decimal point and move it 2 places, and you do that to 8.4.

3 \sqrt{840}


Now, divide the way you would usually do. If there is a remainder, keep adding 0's until you get the answer with no remainder. If the 0 keeps going on and on just stop after 2 0's.

Which describes the first step in solving the equation 4x - 7 = -15?
GalinKa [24]

Answer:

Add 7 to both sides

Step-by-step explanation:

You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.

Then you would get 4x = -8.

Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.

x = -2

Vesna [10]

Answer:

x = 52

Step-by-step explanation:

Vertical angles are angles that are opposite from each other.

A. 25,600π in3<br><br><br><br> B. 10,240π in3<br><br><br><br> C. 1280π in3<br><br><br> D. 640π in3
NeX [460]

Answer: The correct answer is B; 10,240π in³

Step-by-step explanation: To calculate the volume of a cylinder, the given formular is

Volume = π r² h, where

radius (r) = 16

height (h) = 40

Pi (π) = 3.14

It is important to take note that in questions like these, the value of pi is usually given as 3.14 or 22/7. However, for this particular question, the answer should be expressed in terms of pi, (that is, the answer must include pi). For that reason we shall leave pi as it is, and we shall not use it's value when applying the formular.

Therefore, inserting the values of radius, height and pi into our formular, we now have;

Volume = π r² h

Volume = π x 16² x 40

Volume = π x 256 x 40

Volume = π x 10,240

Therefore the exact volume of the cylinder = 10,240π in³
