13/23% = 1300/23 (56.52)

<em>Therefore, 13 is 29% of 1300/23 (56.52)</em>

You first might want to divide 36 by 3, giving you 12. Multiply 12 by 5, which results in your answer of 60in^3. The equation for this is V = 1/3(blh)

a class has 60 students.Given that 85% passed a science test. Find the number of students who failed and then convert o %

Vanyuwa [196]

Given:

Total students = 60

Student passed = 85%

To find:

The number of students who failed and then convert it in %.

Solution:

We have,

Number of passed student = 85% of Total students

= $\dfrac{85}{100}\times 60$

= $51$

So, number of passes students is 51.

Number of students who failed = Total students - Passes students

= $60-51$

= $9$

So, number of students who failed is 9.

$\text{Fail}\%=\dfrac{\text{Failed students}}{\text{Total students}}\times 100$

$\text{Fail}\%=\dfrac{9}{60}\times 100$

$\text{Fail}\%=15$

Therefore, 15% students fail in the test.

Does a triangle with side lengths 7, StartRoot 80 EndRoot, and StartRoot 31 EndRoot from a right triangle?

AlladinOne [14]

Answer and Step-by-step explanation:

The sides we have are 7, $\sqrt{80}$ , and $\sqrt{31}$ .

The square root of 80 is less than 9 but greater than 8 (because $8^2$ is 64, $9^2$ is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.

So, $\sqrt{80}$ is the longest side.

1) The square of $\sqrt{80}$ is: $(\sqrt{80} )^2=80$

2) The sum of the squares of the two shorter sides is:

$7^2+(\sqrt{31} )^2=49+31=80$

3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.

Hope this helps!
