What is another way to write the expression 82p
To convert 82 pints to quarts, divide 82 by the conversion factor of 2, which provides the result of 41 quarts.
Explanation:To rewrite the expression 82p where p represents pints into quarts, first understand that pints are smaller than quarts. Because there are 2 pints in a quart, you use division for the conversion. Since the conversion factor is 2, you would divide the number of pints by 2 to find out how many quarts that is.
To convert 82p, divide 82 by 2:
82 ÷ 2 = 41
Therefore, 82 pints is equal to 41 quarts.

Given that t is the median of the numbers 32, 64, 22, t, 41, 22, and 78, what is the lowest possible value of t?
Final answer:
The lowest possible value for t as the median of the numbers 32, 64, 22, t, 41, 22, and 78 is 32. This value maintains the order when the numbers are arranged from lowest to highest for t to be the median.
Explanation:
To find the lowest possible value for t given that it is the median of the numbers 32, 64, 22, t, 41, 22, and 78, we first need to arrange the numbers in ascending order.
Since there are seven numbers, the median would be the fourth number when sorted.
To ensure t is the lowest possible median, we sort the remaining numbers excluding t. Thus, we have:
22, 22, 32, 41, 64, 78
The third value is 32, and the fifth value is 41, so for t to be the median, t must be greater than or equal to 32 but less than or equal to 41.
However, since we are looking for the lowest possible value of t, t would be 32, as this is the lowest it can be while still being the median of the sorted list.

Suzanne is going to rent a car while she is out of town. One car rental company offers a flat rate of $35 per day plus $0.10 per mile. Another car rental company offers the same car for $25 per day plus $0.25 per mile. She will need the car for 5 days. How many miles would she need to drive for the first rental company to be a better deal?
Answer:
She need to drive more than 2000 miles for the first rental company to be a better deal .
Step-by-step explanation:
Case 1) One car rental company offers a flat rate of $35 per day plus $0.10 per mile
Let m be the no. of miles
She will need the car for 5 days.
So, total cost = [tex]35 \times 5 +0.10m=175+0.10m[/tex]
Case 2) Another car rental company offers the same car for $25 per day plus $0.25 per mile.
Let m be the no. of miles
She will need the car for 5 days.
So, total cost = [tex]25 \times 5 +0.25m=125 +0.25m[/tex]
Now we are supposed to find How many miles would she need to drive for the first rental company to be a better deal?
So, [tex]175+0.10m <125 +0.25m [/tex]
[tex]175+125 <125 +0.25m-0.10m [/tex]
[tex]300 < 0.15m [/tex]
[tex]\frac{300}{0.15} < m [/tex]
[tex]2000 < m [/tex]
So, she need to drive more than 2000 miles for the first rental company to be a better deal
Lucas is applying to both Stanford and Cal-poly. The probability that he gets accepted to Stanford is 0.4. The probability that he gets accepted to Cal-Poly is 0.3. The probability that he is accepted to both schools is 0.15.
a) What is the probability that he is accepted to one of the two schools?
b) What is the probability that he does not get accepted at either school?
The probability that Lucas is accepted to at least one of the two schools is 55%, while the probability that he does not get into either school is 45%.
Explanation:The subject of the question is probability theory, which is a branch of mathematics. Lucas has a 0.4 chance of getting into Stanford, a 0.3 chance of getting into Cal-Poly, and a 0.15 chance of getting into both. These are independent probabilities because they do not affect each other.
a) To calculate the probability that he gets accepted to at least one of the schools, we add the probabilities of him getting into each school, and then subtract the probability of him getting into both (because we're double counting that scenario). So, that's 0.3 (for Cal-Poly) + 0.4 (for Stanford) - 0.15 (for both) = 0.55, or 55%.
b) In probability theory, the total probability of all possibilities is always 1. So, to find the probability that he doesn't get into EITHER school, we subtract the probability that he gets into at least one school from 1. So, 1 - 0.55 (the answer from part a) = 0.45, or 45%. So, there's a 45% chance that Lucas doesn't get accepted into either school.

Name an angle adjacent to ∠DGE
Choices:
∠FGI
∠EGH
∠HGJ
Answer:
The answer is ∠EGH.
Step-by-step explanation:
In order to determine the correct option, we have to know about adjacent angle.
Two angles are adjacent when they have a common side and vertex (corner point). So in this case, the adjacent angle must have GE or DG common side and the G vertex.
According to the options, the adjacent angle to ∠DGE is:
∠EGH
The other options are not adjacent angles because they do not have a common side.
Finally the correct option is ∠EGH.

what is the quotient when -3^3 +5x+14 is divided by x-2? pleas hurry
The quotient is -3x² + 3x + 8.
To find the quotient when [tex]\(-3x^3 + 5x + 14\)[/tex] is divided by x - 2, we can use polynomial long division.
The dividend is [tex]\(-3x^3 + 0x^2 + 5x + 14\)[/tex] (since there is no [tex]\(x^2\)[/tex] term) and the divisor is x - 2.
1. Divide the first term of the dividend by the first term of the divisor: [tex]\(-3x^3 \div x = -3x^2\)[/tex].
2. Multiply the divisor by the result of step 1: [tex]\((-3x^2)(x - 2) = -3x^3 + 6x^2\).[/tex]
3. Subtract the result of step 2 from the dividend: [tex]\((-3x^3 + 0x^2 + 5x + 14) - (-3x^3 + 6x^2) = -6x^2 + 5x + 14\).[/tex]
4. Repeat the process with the new dividend [tex]\(-6x^2 + 5x + 14\)[/tex].
Continuing the division process, we find the quotient:
[tex]\[ \frac{-3x^3 + 5x + 14}{x - 2} = -3x^2 + 3x + 8 \][/tex]
So, the quotient is -3x² + 3x + 8.
What is the value of the function y=2x−3 when x=−1 ?
A linear model projects that the number of bachelor's degrees awarded in the United State will increase by 19,500 each year. In 2001, 1.28 million bachelor's degrees were awarded. Use the inverse function to predict the number of years after 2001 that 1.7 million bachelor's degrees will be awarded.
The linear model predicts that approximately 22 years after 2001 (around the year 2023), 1.7 million bachelor's degrees will be awarded annually in the U.S.
Explanation:The problem is related to the mathematical concept of linear modeling. This model is represented by the function f(x) = 19500x + 1.28 million, where x is the number of years after 2001 and f(x) is the number of bachelor's degrees awarded in that year. The objective is to calculate 'x' when f(x) is 1.7 million. To do this, we use the inverse function.
The inverse function of f(x) = 19500x + 1.28 million is the function x = (f(x) - 1.28 million) / 19500. Substituting the known value f(x) = 1.7 million into the equation, we get: x = (1.7 million - 1.28 million) / 19500 ≈ 21.54. Since we cannot have a fraction of a year, we round this up to the next whole number.
Therefore, according to the linear model, it will be approximately 22 years after 2001, i.e., in the year 2023, when the number of bachelor's degrees awarded is expected to reach 1.7 million.

Using the linear model, it is predicted that 1.7 million bachelor's degrees will be awarded approximately 22 years after 2001, which corresponds to the year 2023.
Explanation:To predict the number of years after 2001 that 1.7 million bachelor's degrees will be awarded using a linear model, we start with the initial number of degrees awarded in 2001, which is 1.28 million. According to the model, the number of bachelor's degrees increases by 19,500 each year. We set up the equation: 1.28 million + 19,500x = 1.7 million. Here, x represents the number of years after 2001.
Solving for x gives us:
1.7 million - 1.28 million = 19,500x
420,000 = 19,500x
x = 420,000 / 19,500
x ≈ 21.54
Thus, it will take approximately 22 years after 2001 for 1.7 million bachelor's degrees to be awarded, which means this is expected to occur in the year 2023 (since 2001 + 22 = 2023).
