Can someone help me with this please? In Belleville, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 miles and the distance between the courthouse and the city pool is 15 miles, how far is the library from the community pool?

Answers

Answer:

12 miles

Step-by-step explanation:

A right triangle is formed, where the distance between the library and the courthouse is one leg ( = 9 miles), the distance between the library and the swimming pool is the other leg (let's call it x), and the distance between the swimming pool and the courthouse is the hypotenuse ( = 15 miles).

From Pythagorean theorem:

15² = 9² + x²

225 - 81 = x²

x = √144

x = 12 miles

What's the probability of rolling a prime number on a fair die

Answers

Answer:

50% chance

Step-by-step explanation:

if it's a six-sided die, the options are 2, 3, and 5. that's three numbers out of six, or half (50%)

Answer:

1/2 ; 50%

Step-by-step explanation:

Probability is number of desired outcomes/number of total outcomes.

In a fair die, there are 6 total outcomes.

Now, let's find how many desired outcomes there are.

We can do this by naming the prime numbers form 1-6.

Prime numbers are numbers that are divisible by 2 positive integers: 1 and itself.

This means that 1, 4, and 6 are not prime numbers.

The prime numbers are: 2, 3, and 5.

So there are 3 desired outcomes.

That means the probability would be 3/6

This can be simplified to 1/2, or 50%

A square has one of its sides increased by 7 inches and the other side decreased by 4 inches. Which of the following represents the area of the square?

Answers

Answer:

Step-by-step explanation:

both the length and the width of a square is the same measurement.

so if both measured to "x" then that means one side increase +7.

so one side is x + 7

and the other side decreased -4

so the other side is x - 4

area of square = length x width or just one of the sides to the power of 2

so (x+7) * (x-4) = Area

x^2 + 3x - 21 = area

Answer:

x^2-11x+24

Step-by-step explanation:

The area of a quad is lw

So, the formula would be (x-7)(x-4)

When you multiply it, it turns to be x^2 - 11x + 24

Answers

Answer:

z = [tex]\frac{1}{5}[/tex], z = 3

Step-by-step explanation:

The absolute value function always returns a positive value.

However, the expression inside can be positive or negative, that is

5z - 8 = 7 ( add 8 to both sides )

5z = 15 ( divide both sides by 5 )

z = 3

OR

- (5z - 8) = 7

- 5z + 8 = 7 ( subtract 8 from both sides )

- 5z = - 1 ( divide both sides by - 5 )

z = [tex]\frac{1}{5}[/tex]

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions

z = 3

left side = | 15 - 8 | = | 7 | = 7 = right side

z = [tex]\frac{1}{5}[/tex]

left side = | 1 - 8 | = | - 7 | = 7 = right side

Thus z = [tex]\frac{1}{5}[/tex], z = 3 are the solutions
