A box is 20 centimeters long and 30 centimeters high. It's volume is 3,600 cubic centimeters. What is the width of the box?

Answers

Answer 1
Answer: We can start by looking at what we know.

We know that volume is equal to length x width x height. Filling in this equation with the values we're given:
20cm x width x 30cm =
3600cm^3

If we divide both sides by 20cm we get:
width x 30cm = 180cm^2

Next we can divide both sides by 30cm to get our answer:

width = 6cm
Answer 2
Answer: First you have to add 20 and 30. That gives you 50. Then you divide 3,600 by 50 and that is 72. So 72 is the width.

the surface area of a square pyramid is 189 square inches. The side length of the base is 7 inches. What is the value of x?

Answers

To know the answer in the problem above, we will use the formula for getting the surface area of a square pyramid where one side of the base is 7 inches and the surface area is 189 sq inches and x is the height of the square pyramid. In equation, A= a^2 + 2a√a^2 / 4 + h^2 . The height would be, 9.39 inches.

5+3=4d please help me

Answers

5 + 3 = 4d

First, add '5 + 3' to get '8'.
8 = 4d

Second, divide both sides by '4', leaving the 'd' by itself.
(8)/(4) = d

Third,  (8 ÷ 4), simplify the fraction to '2'.
2 = d

Fourth, you can switch your sides.
d = 2

Answer: \fbox {d = 2}


So the object of this problem is to find out the value of d.

To do this, first think about 5 + 3. This equals 8, right? So the value of d times 4 has to equal 8.

No other number besides 2 would make sense. 2 would equal d because 4 x 2 is 8, and 5 + 3 is 8.

So you would write the answer as:

5+3=4(2)

Explain how to distinguish between a rational number and an irrational number

Answers

Sample Response: A rational number can be expressed as a whole number, a fraction, or decimal that has either terminating or repeating digits. A square root of a perfect square is rational. If it is none of these, then the number is irrational.

The length of a rectangle is 4 units shorter than one-fourth of the width, x. Write an expression that represents the perimeter of the rectangle (use one variable and a fraction)

Answers

Perimeter is the sum all lengths of a shape. For a rectangle, the perimeter is calculated by adding the 2 lengths and 2 widths. It is expressed as:

P = 2l + 2w

From the data of the length and width above, we form an expression:

P = 2l + 2w
P = 2(w/4 - 4) + 2w
P = 2w/4 - 8 + 2w
P = 5w/2 - 8

What is compound interest?

It refers to the interest calculated on the principal and accumulated interest. Sum of cash after t years if interest is compounded continuously is Pe^(rt).

How to calculate sum after compounding?

The principal amount= $ 1500, rate of interest=4%, time period=2 years.

Sum after 2 years when interest is compounded continuously may be calculated as under:

Sum=1500*e^(0.04*2)

=1500*e^(0.08)

=1500*1.0833 [e^(0.08)=1.0833]

=1624.95

Hence we'll get $1624.95 after 2 years if interest is compounded continuously.
