Answer:

PLZ GIVE ME BRANLIEST =)))

1. A scientific notation is where you multiply any number by a power of 10 (negative or positive or neutral).

2. This is incorrect, because 3.825*10^6 is actually 3,825,000. The correct answer is 3.825*10^5.

3a) The power is supposed to be negative, since the number is decreasing, not increasing. It is 4.25*10^-5. 3b) The processes are alike in the way that they all have a number being multiplied by a power of 10. They are all different in the way that some numbers can be decimals, and some powers can be negative powers.

17. The length of a rectangle is 12 in, and the perimeter is 56 in. Find the width of the rectangle.

Ivahew [28]

Answer:

Step-by-step explanation:

P = 2(L + W)

P = 56

L = 12

now sub...we are looking for w

56 = 2(12 + W)

56 = 24 + 2W

56 - 24 = 2W

32 = 2W

32/2 = W

16 = W <==== the width is 16 inches

check...

P = 2(L + W)

56 = 2(12 + 16)

56 = 2(28)

56 = 56 (correct)

Answer:

16.75 cubic inches

Step-by-step explanation:

<u>Key skills needed: Volume of a cylinder, Volume of a sphere</u>

1) To get the answer to this problem, you need to understand two formulas: The volume of a sphere, and The volume of a cylinder.

Volume of a sphere --> $V= \frac{4}{3}\pi r^3$ (V = volume, and r = radius)
Volume of a cylinder --> $V = \pi r^2h$ (V = volume, r = radius,h = height)

These formulas will be needed.

2) In order to solve this problem, we need to find the volumes of both, and the subtract them from one another to find the difference.

3) Let's start by finding the volumes:

Cylinder --> $V = \pi r^2h$

We have the radius (which is 2) and the height (which is 4)

This means we can solve --> $V = \pi(2^2)(4)$

2 squared is 4, so then it would be --> $V = \pi (4)(4)$
4 times 4 is 16 so $V = 16\pi$ ---> 16 pi is the same as 50.24 cubic inches (if you use 3.14 as pi).
Next is the Sphere--> $V = \frac{4}{3}\pi r^3$

We have the radius (which is 2) so we can solve

$V = \frac{4}{3}\pi (2^3)$
2 cubed is 8, so it would be --> $V = \frac{4}{3}\pi (8)$
8 times 4/3 is 32/3 so --> $V = \frac{32}{3}\pi$ --> which is Around 33.51 cubic inches
