What is the missing dimension of a rectangle or prism with the following dimensions and volume? Length 3 cm width 5 cm volume 45

olasank [31]

Hello!

In order to find out the volume of any prism, you are to do length x width x height.

Because we only know the length and the width, we can multiply those to get started. 3 x 5 is 15, so we know that's what we can start with.

Because we know the volume, all we have to do is do h x 15 = volume (45). Now, what is height?

In order to find the height, we must find a number that, when multiplied by 15, equals 45.

So we can try out 3, which when multiplied by 15, equals 45.

That means 3 is your height.

Hope I helped! :)

During two years, the population of birds of an island became 7 times more than before. If the first year increase in the popula

nordsb [41]

Answer:

The percent increase of the second year is 400%.

Step-by-step explanation:

Consider the provided information.

Let the population of birds was x.

After 2 years the population becomes 7 times more than before.

Therefore, after 2 years population is 7x.

In first year increase in the population was 40%.

Population after 1st year = x + 40% of x

Population after 1st year = x + 0.40x

Population after 1st year = 1.4x

The population increase from 1st year to 2nd year is: 7x-1.4x=5.6x

Thus the percentage increase is:

$\% increase=\frac{5.6x}{1.4x}\times100=400\%$

Hence, in second year the population of birds increase by 400%.

Ugo [173]

We can solve this by setting up a proportion:

12 seeing the play/ 72 students = 210 seeing the play/ x students

We can cross multiply to solve for x:

(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school

Amanda [17]

(x - 8)² = 144

Take square root of both sides

(x - 8) = √144

x - 8 = 12

x = 12 + 8

x = 20

Original lawn is = 20 feet * 20 feet square
