Angle PQR and angle TQV are vertical angles. The measures of the two angles have a sum of 100o. Write and solve an equation to find x, the measures of angle TQV.
Answer:
I'm not certain what the sum is, so I will teach you how to solve.
Step-by-step explanation:
As the question states, angle PQR and TQV are vertical angles, so they have to be the same measure. Just divide the sum by 2 and you get the answer.
If there were more context, I would totally edit my answer!

An uncooked gingerbread cookie is y centimeters long. After it is baked, the length of the cookie increases by 25%. Which expression best represents the new length of the cookie?
Answer:
1.25 y
The full length is 1 y, so to increase it by 25% (0.25), then it would be 1.25 y.

Liz flips a coin 90 times. The coin lands head up 63 times and tails up 27 times. The theoretical probability of the coin landing heads up is ___%.
Answer:
50%
Step-by-step explanation:
This question asks for the theoretical probability
In order to find theoretical probability, we find how many outcomes are possible, and how likely each action is.
In this case, we are flipping a coin. There are only two possible outcomes of this, which are heads and tails. Each of these are equally likely, so that would mean the theoretical probability of flipping it and it landing heads up is 50%
Answer:
P(head up) = 70%Explanation:
P(head up) = 63/90
P(head up) = 7/10
P(head up) = 70%

What is the radius, in centimeters, of a circle that has a circumference of 16π?
8
16
32
64
Answer: The radius equals 8cm
Answer:
8
Step-by-step explanation:
The circumference of a circle is equal to π , which is a number ≈ 3.14 , multiplied by the diameter of the circle.
Therefore, C = π d .
We know that the circumference, C , is 16 π , so we can say that:
16 π = π d
We can divide both sides by π to see that 16 = d .
We now know that the diameter of the circle is 16 .
We also know that the diameter has twice the length of the radius.
In equation form: 2 r = d
2 r = 16
r = 8
Note that since 2 r = d , the equation C = 2 π r holds and can be used in place of C = π d .

A Ferris wheel has a diameter of 212 feet. How far will one passenger travel in one revolution of the wheel? Explain your answer
Answer: 665.68 ft
Step-by-step explanation:
You‘re trying to find the circumference of the Ferris wheel. The formula for circumference is C=3.14(approximation for pi)x the diameter. So you would do 3.14 x 212 = 665.68
Brainliest if you can answer question 12 right :)
Please Help Me!!!!!!
Answer:
Step-by-step explanation:
Min. = 7
Max. = 13
Median = 10
Q1 = 8
Q3 = 12
IQR = 4
Step-by-step explanation:
Sorting it in order: 7, 8, 9, 10, 11, 12, 13
To find the median: Look for the middle number. In this case, the middle number is 10.
To find the 1st quartile: The first quartile is the median of the first half of the data. So, the first half of the data is 7, 8, 9. The median is 8.
To find the 3rd quartile: The third quartile is like the 1st quartile, but it's on the other end. So, it contains 11, 12, 13. The median of that is 12.
To find the maximum: The maximum is the largest number in the data set. So, in this case, it is 13.
To find the minimum: The minimum is the smallest number in the data set. In this case, it is 7.
Data in all: median: 10 1st Quartile: 8 3rd Quartile: 12 Min: 7 Max: 13

Step-by-step explanation:
b = bagels
c = cream cheese
Given
b = 30
c = 2
Work:
0.85b+2.5c
0.85(30) + 2.5(2)
25.5 + 5

You are stuck in a big traffic jam on the freeway and you are wondering how long it will take to get to the next exit, which is 1 1/2 miles away. You are timing your progress and find that you can travel 2/3 of a mile in one hour. If you continue to make progress at this rate, how long will it be until you reach the exit? Solve the problem with a diagram and explain your answer.
Answer:
2.25 hours
Step-by-step explanation:
Because 2/3 as a decimal is 0.66666666666 and of course 1 1/2 miles is 1.5, so you divide 1.5 by 0.66666666666 and then round it to the nearest hundreth. So there you go, hope this helped :)

Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:
Dam A
f(t) = 5t – 7t – 1
Dam B
g(t) = 3t 2 + 4t + 9
Which function represents the difference in the amounts of water released, h(t) = f(t) – g(t)?
h(t) = 3t 2 – 5t + 11t + 10
h(t) = 2t 2 – 11t – 10
h(t) = 5t – 3t 2 – 3t + 8
h(t) = 5t – 3t 2 – 11t – 10
