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 1

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

Which expression is equivalent to: 7^14 divided by 7^2?
A. 7^16
B. 1^7
C. 7^7
D. 7^12

Answers

Answer:

7^12  or 7 to the 12th power!

Step-by-step explanation:

[tex]7^{14}[/tex] ÷ [tex]7^{2}[/tex] = [tex]7^{12}[/tex]

14-2=12

7 stays as the base so

[tex]7^{12}[/tex]

The solution is, 7^12  or 7 to the 12th power, is the expression which is equivalent to: 7^14 divided by 7^2.

What is division?

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

7^14 divided by 7^2

now, we have to find the expression which is equivalent to: 7^14 divided by 7^2.

so, we have,

7^14 ÷ 7^2

= 7^14 / 7^2

=7^14-2

as, we know that,

14-2=12

so, we get,

7^14-2

=7^12

as, we know,

7 stays as the base so,

7^14 ÷ 7^2 = 7^12

Hence, The solution is, 7^12  or 7 to the 12th power, is the expression which is equivalent to: 7^14 divided by 7^2.

A bag of apples that cost $4.75 is on sale for 30%.
What is the sale cost?

Answers

Answer:

$3.32

Step-by-step explanation:

You take 30% of 4.75. You multiply 0.30 times 4.75. Then you subract that from 4.75. Boom.

Answer:

$3.33

Step-by-step explanation:

$4.75 by 30 then divide it by one hundred. So, the discount is equal to $1.43. To calculate the sales price, simply deduct the discount of $1.43 from the original price $4.75 then get $3.33 as the sales price.

When a fair 6-sided dice is rolled 10 times, the resulting face values are as
follows: 1, 2, 6, 5, 5, 6, 3, 4, 5, 1. After conducting the experiment, the researcher
claims that P(5) = .30. This is an example of ______
probability.

Answers

Answer:

This is an example of independent probability.

Step-by-step explanation:

Independent events are not affected by previous events, just like the outcome of rolling a dice is not effected by the previous outcome. (The dice has no memory of any kind, what so ever!).

When two events are said to be independent of each other, meaning the probability that one event occurs in no way affects the probability of the other event occurring. Another example of an independent event is when you flip a coin. (The coin has no memory of any kind, what so ever!).

Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:

P(A and B) = P(A) · P(B)

The dice was cast 10 times. In three occasions a 5 came out, and in 7 occasions another outcome occurred. The probability of the outcome of exactly 3 times a 5 in 10 casts, can be calculated as:

P(5) =(1 / 6)^3 + (5 / 6)^7

P(5) = 0.28

P(5) = .3

A dog run has an area of at least 150 square feet. The length of the run has to be 12 feet. What us the width of the run?​

Answers

Answer:

The width is 12.5

Step-by-step explanation:

so you would do 150 divided by 12 which would give you 12.5 so the width has to be 12.5 because length times width = area and 12.5 time 12 = 150

Hope this helped :3  o(* ̄▽ ̄*)ブ

Answer:

12.5 ft

Step-by-step explanation:

Area of a rectangle of length L and width W:  A = L * W

Then 150 ft^2 = (12 ft)(width), and so:

(width) = (150 ft^2) / (12 ft) = 12.5 ft

Find the 44th term in the following
arithmetic sequence :

Answers

Answer:

45

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 3 - 2 = 1, thus

[tex]a_{44}[/tex] = 2 + (43 × 1) = 2 + 43 = 45

the answer is 45

Answer:

w=9z

Step-by-step explanation:

For each z value, w is 9 times that. For instance, 18 is 9 times 2, and 45 is 9 times 5. Therefore, the equation that would describe this is w=9z. Hope this helps!

Answer:

z = (1/9) w or w = 9z

Step-by-step explanation:

w = 18 , z = 2

if relationship is proportional than z = k (constant) *w

2 = k * 18 divide each side by 18

k = 2/18 = 1/9

A letter L with a height of 9 inches is drawn on the actual flag. What should be the height and inches of a letter L in the scale drawing? Explain plzzz....

Answers

Answer:

0.5 inch on the drawing

Step-by-step explanation:

The following information is missing:

The scale factor of the drawing to the actual flag is represented by the ratio 1:18.

This scale factor means that 1 inch on the drawing are equivalent to 18 inches o n the actual flag. We want to know the height on the drawing, given that a height of 9 inches is drawn on the actual flag. The following proportion must be satisfied:

1 inch on the drawing / x inch on the drawing = 18 inches o n the actual flag / 9 inches o n the actual flag

x = 9/18 = 0.5 inch on the drawing
