Answer: 1. sqrt(19); 2. sqrt (96); 3. sqrt (105); 4. sqrt (28)

Step-by-step explanation: All you have to do is use Pythagoras' Theorem.

So, e.g. in question 1, the equation would be x^2 + 9^2 = 10^2.

x^2 = 100 - 81

x^2 = 19

Therefore, x = sqrt (19) or (19)^1/2

BTW, sqrt means square root.

And now you apply it for everything else.

Suppose the tree diagram below represents all the students in a high school and that one of these students were chosen at random
andrey2020 [161]
The question is: If the student is known to be the girl (300 girls) what is the probability of being right handed.

We know that there are 300 girls, and that out of those 300, there are 250 girls right handed. 

Divide 250 with 300

250/300 = 0.83333, or 83.33%

0.83333, or 83.33% is your answer

hope this helps

A company has made a rubber ball for $0. 02 per square foot. The company wants to spend a maximum of $1 each on a new ball.
Misha Larkins [42]

The diameter of the new rubber ball, to the nearest foot, must be D =  4.0 ft (in the case of the maximum cost).

<h3>How to find the diameter of the ball?</h3>

Remember that for a sphere of diameter D, the surface area is:

A = 4*pi*(D/2)^2

In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:

$0.02*A = $1

A = $1/$0.02 = 50

So the surface of the ball must be 50 square feet.

Then we solve:

50ft^2 = 4*3.14*(D/2)^2

D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft
