Answer:

0.07%

Step-by-step explanation:

This equation is solving for what percentage of 100 kg is 0.07 kg.

1. Set up the equation

$\frac{0.07}{100}$ = $\frac{x}{100}$

0.07 kg out of 100 kg is equal to x out of 100 because x represents the percentage and percentages are out of 100.

2. Solve by cross multiplying

100x = 7

3. Solve for x by dividing both sides by 100

x = 0.07

The answer is 0.07%

You are an engineer for a company that produces shipping boxes. The boxes that are made on one machine are all in the shape of a

Sidana [21]

Answer:

Step-by-step explanation:

Draw a picture of a cube and label the cube's side length, s. Prior to placing your order for more cardboard, tape, packing material, etc. your boss asked you to determine each of the following: a. Write an expression to determine the surface area of a cube-shaped box, SA, in terms of its side length, s (in inches).

The surface area of a cube of side length s is A = 6s^2; there are 6 sides each of area s^2.

If s is measured in inches, then A = 6x^2 inches^2.

b. Define a formula to determine the volume of a cube-shaped box, V, in terms of its side length, s, (in inches). Preview What are the units for the cube's volume?

The formula for the volume of a cube is V = s^3. In this case, V is measured in inches^3.

c. Given the formula for determining the volume of a 4 sphere is V = ar atrs, 3 (This is incorrect; the formula in question, for the volume of a sphere of radius r is V = (4/3)(pi)r^3. (1) We can solve this formula for r^3, and then for r:

3V = 4(pi)r^3 becomes r^3 = ------------

4(pi)

and so the formula for the radius of a sphere whose volume is 87 inches^3

∛(3V) ∛3*87 in^3

r = ------------ = ------------------

∛(4pi) ∛(4pi)

(2) The volume of the sphere when r = 5.9 in is:

4(3.14) 205.38 in³

(4/3)(pi)r^3 = (4/3)(pi)(5.9 in)³ = --------- = --------------------- = 67.46 in³

3 3

(3) V = (4/3)(pi)r³

Please share the possible answer choices. Basically, you must find the volume twice: once for a radius of 4 in and once for a radius of 2 in. Then subtract the smaller from the larger. The numerical result is the desired answer.

When a number is decreased by 8.5%, the result is 33. What is the original number to the nearest tenth?

Reil [10]

Answer:

Step-by-step explanation:

Let the original number be x

(100-8.5)% of x = 33

91.5% of x = 33

$\frac{91.5}{100}x=33\\\\x=33*\frac{100}{91.5}\\\\x=36.07$
