Answer:

The answer is 0.045

Step-by-step explanation:

1. Use this formula V=lwh

0.5 x 0.4 x 0.15 = 0.03

That is the volume of the lower prism

2. Do V=lwh again for the volume of the upper prism

0.5 x 0.15 x 0.2 = 0.015

Answers

Answer:

W = 8.2 cm

Step-by-step explanation:

The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.

Thus, 65.6 cm = 2W + 2L.  Substituting 3W for L, we get

          65.6 cm = 2W + 2(3W) = 8W.

Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or

W = 8.2 cm

W=8.2 cm. Trust me I have my sources.

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction of pizza each friend gets is A

Now , the total number of friends = 5

The number of pizzas = 4

So , the fraction is A = 4/5

Answers

The answer is 12843.75 dollars

Answer:

343.75 dollars

Step-by-step explanation:

First I like to solve for the value of 1% which is 125 then we solve for .10% which is 12.5 then we solve for .01% which is 1.25 I find this helpful because now we have the unit amount for each percent we use in this equation now to multiply we have .05 percent so we take our 1.25 value for .01 percent and multiply by 5 which give us 6.25 then we do .7% we take our .1 percent value and multiply 12.5 x 7 give us 87.5 then we do the 2% we take our 1 percent value and multiply by 2 125 x 2 give us 250 now we add it all together 250+87.5+6.25 = 343.75 I hope this help you out :)
