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

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%
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.

The histogram shows the scores on a recent science test.
Using the histogram, select all of the true statements that describe the data.
(Pls help the correct answer gets brainiest)
Also, remember to look at all the pages.
And their is more than one answer
Answer:
Answer In Explanation
Step-by-step explanation:
O More Than Half Of The Students Scored 81 Or Better
O The Same Number Of Students Scored Between 81 And 90 On The Test As Scored Between 61 And 80
-The Last One Is Confusing Because It Doesn't Say 71-80
Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.
What is a histogram?A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
For the given situation,
The histogram shows the scores on a recent science test.
We need to check the options, which statements describe the data.
Option A: Only two students scored less than 71 on the test.
There are four students scored less than 71.
So option A is false.
Option B: More than half of the students scored 81 or better on the test.
Students scored more than 81 = [tex]16+8[/tex]
⇒ [tex]24[/tex]
Total number of students = [tex]40[/tex]
Half of the students = [tex]\frac{40}{2}[/tex]
⇒ [tex]20[/tex]
Thus, [tex]24 > 20[/tex]
So option B is true.
Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.
Students scored between 91 and 100 = [tex]8[/tex]
Students scored between 71 and 80 = 12
⇒ [tex]8 < 12[/tex]
So option C is false.
Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.
Students scored between 81 and 90 = [tex]16[/tex]
Students scored between 61 and 80 = [tex]4+12[/tex]
⇒ [tex]16[/tex]
Thus, [tex]16=16[/tex]
So, option D is true.
Option E: There were 12 students who scored 80 on the test.
The score range is between 71 to 80. So we could not predict the number of students who score 81.
So option E is false.
Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

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

In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?
Answer:
i think it is 45.70
Step-by-step explanation:
Answer:
$48.55
Step-by-step explanation:
Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including taxEquation:
17% = 0.17
Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.
0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use
58.50 - 9.95 = 48.55
So $48.55 is your answer
