Answer:
Triangle PQR is a right triangle therefore you can use the pythagorean theorem to find the length of PR which is the same as the hypothenuse
Step-by-step explanation:
Theorem:
(QP)² + (QR)² = (PR)²
(6)² + (14)² = 232 ⇒ (PR)² = 232 then PR = √232 = 15.23
If PR is adjusted to 16 feet then we use the Pythagorean theorem again to find the height QR
(QR)² + (14)² = (16)²
(QR)² = 256 - 196 = 60 ⇒ QR = √60 = 7.75.

Answer:
1. There is no change in the number of state representatives for fourth state after the last census.
2. We have been given a table that shows the record low temperatures for several states. We are asked to graph the temperatures on a number line.
First of all we will draw a number line going to infinity into both directions.
To graph the given temperatures on number line let us arrange temperatures in less negative order.
-34, -32, -30, -29, -27.
Since we know that numbers with large negative values lie on the left at number line. Let us graph our large negative temperature on the left at our number line.
We can see that -34 is the most negative temperature, therefore, it will be on the left most side of our number line.
-27 is greatest of our given negative temperatures. -27 is less negative temperature than our other given low temperatures, therefore, it will lie on the right most side of our number line.
Other temperatures will lie between these two values according to their temperatures.
-32 is second large negative temperature after -34, therefore, it will lie on the right side of -34.
-30 will lie on the right side of -32 and -29 will lie on the right of -32.

A restaurant has a sign by the front door that says, "Maximum occupancy: 75 people." Answer each question and explain or show your reasoning.
What percentage of its capacity is 9 people?
What percentage of its capacity is 51 people?
What percentage of its capacity is 84 people?
Step-by-step explanation:
9/75 * 100% =
51/75 * 100% =
84 /75 * 100% =
The percentage of its capacity is 9 people, 51 people, and 84 will be 12%, 68%, and 112%, respectively.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A restaurant's front entrance is marked with the words "Maximum occupancy: 75 persons."
The percentage of its capacity is 9 people is given as,
P = (9/75) x 100
P = 12%
The number of people is less than the maximum capacity.
The percentage of its capacity is 51 people is given as,
P = (51/75) x 100
P = 68%
The number of people is less than the maximum capacity.
The percentage of its capacity is 84 people is given as,
P = (84/75) x 100
P = 112%
The number of people is more than the maximum capacity.

What is the approximate radius of a sphere with a volume of 1436 cm^3?
Answer: 7 cm
Step-by-step explanation:
The approximate radius of a sphere with a volume of 1436 cm³ will be 7 cm.
What is the volume of the sphere?Let r be the radius of the sphere.
Then the volume of the sphere will be
V = 4/3 πr³ cubic units
The volume of the sphere will be 1463 cm³.
Then the radius will be
1436 = 4/3 πr³
1077 = πr³
342.82 = r³
r = 6.998
r ≈ 7 cm

For each pair of points, find the slope of the line that passes through both points. If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler.
Answer: The answer is number choice 1.
Step-by-step explanation:
The slope of each pair of coordinates are as follows -
Pair 1 → (1, 1) and (7, 5) → m[1] = 2/3
Pair 2 → (1, 1) and (5, 7) → m[2] = 3/2
Pair 3 → (2, 5) and (-1, 2) → m[3] = 1
Pair 4 → (2, 5) and (-7, -4) → m[4] = 1
What is Slope of a line?Slope of a line is defined as the rate of change of dependent variable with respect to independent one.
Given are the four pairs of coordinates.
The formula to calculate the slope of a line using the coordinates is -
m = (y₂ - y₁) / (x₂ - x₁)
→ for (1, 1) and (7, 5), the slope will be -
m[1] = (5 - 1)/(7 - 1)
m[1] = 4/6
m[1] = 2/3
→ for (1, 1) and (5, 7), the slope will be -
m[2] = (7 - 1)/(5 - 1)
m[2] = 6/4
m[2] = 3/2
→ for (2, 5) and (-1, 2), the slope will be -
m[3] = (2 - 5)/(-1 - 2)
m[3] = -3/-3
m[3] = 1
→ for (2, 5) and (-7, -4), the slope will be -
m[4] = (- 4 - 5)/(-7 - 2)
m[4] = -9/-9
m[4] = 1
Therefore, we can write the slope of each pair of coordinates as -
Pair 1 → (1, 1) and (7, 5) → m[1] = 2/3
Pair 2 → (1, 1) and (5, 7) → m[2] = 3/2
Pair 3 → (2, 5) and (-1, 2) → m[3] = 1
Pair 4 → (2, 5) and (-7, -4) → m[4] = 1

A video game is on sale at Amazon for 35% off the original price of $28.50. Both Pat and Henri want to purchase the game, but they only have $21 each. They will have to pay 10% sales tax. Pat and Henri have different strategies to calculate the price and decide if they have enough money to get the game.
Pat takes 35% of $28.50 and subtracts that from the original price. She takes 10% of the sale price and adds it to the sale price to find the total amount she would have to pay.
Henri finds 65% of the original price and then calculates 110% of the sale price.
Will Pat's strategy calculate the correct total? Explain the calculations.
Will Henri's strategy calculate the correct total? Explain the calculations.
Do they each have enough to purchase the game?
Explain your answers using complete sentences and show your work.
Answer:
yes pat will, because he is taking 35% off of the original price to get the sales price. no henry wont, because the total is supposed to go down not up. no they will not be able to buy 1 for each of them because 1 game costs $18.70
Step-by-step explanation:
28.50/100=0.285
0.285=0.28
0.28*35=9.80
28.50-9.80=18.70
