If the diagonal of a square is approximately 12.73, what is the length of its sides?

Alja [10]

Answer:

The length of the sides of the square is 9.0015

Step-by-step explanation:

Given

The diagonal of a square = 12.73

Required

The length of its side

Let the length and the diagonal of the square be represented by L and D, respectively.

So that

D = 12.73

The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

$D^{2} = L^{2} + L^{2}$

Solving further, we have

$D^{2} = 2L^{2}$

Divide both sides by 2

$\frac{D^{2}}{2} = \frac{2L^{2}}{2}$

$\frac{D^{2}}{2} = L^2$

Take Square root of both sides

$\sqrt{\frac{D^{2}}{2}} = \sqrt{L^2}$

$\sqrt{\frac{D^{2}}{2}} = L$

Reorder

$L = \sqrt{\frac{D^{2}}{2}}$

Now, the value of L can be calculated by substituting 12.73 for D

$L = \sqrt{\frac{12.73^{2}}{2}}$

$L = \sqrt{\frac{162.0529}{2}}$

$L = \sqrt{{81.02645}$

$L = 9.001469325$

$L = 9.0015$ (Approximated)

Hence, the length of the sides of the square is approximately 9.0015

A large container holds 5 gallons of water. It begins leaking at a constant rate. After 10 minutes, the container has 3 gallons

Anna007 [38]

5 - 10 x = 3
10 x = 5 - 3
10 x = 2
x = 10 : 5
x = 0.2
The rate is : 0.2 gallons / minute
5 - t * 0.2 = 0
t * 0.2 = 5
t = 5 : 0.2
t = 25 min
Answer: After 25 minutes the container will be empty.

What is 20% by 37 decreased

Ghella [55]

Answer:

37 decreased by 20% is 29.6.

Step-by-step explanation:

To do this, what we do is simply take 20% of 37 and subtract it from 37.

20% of 37. A trick to easily figure this out is multipling 37 by 20 and dividing by 100.

37*20 = 740

740 / 100 = 7.40

37 - 7.40 = 29.6

37 decreased by 20% is 29.6.

Sarah and get four friends go fishing. They catch 16 fish on Saturday and 14 fish on Sunday. They share the fish equally. How ma

Novay_Z [31]

Answer:

6 fishes

Step-by-step explanation:

The question here is to find the number of fishes each person gets.

To solve this, we need to know the total amount of fishes caught and the number of persons that would be involved in the sharing.

From the question, we can see that they caught 16 fishes on Saturday and 14 fishes on Sunday. The total number of fishes caught is thus 16 + 14 = 30 fishes

This means they caught a total of 30 fishes on both days. Now they share equally the number of fishes. The number of persons is a total of 5. Hence we are looking at sharing 30 fishes equally among 5 persons.

Thus, each person will get 30/5 fishes which equals 6 fishes per person
