Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

What is the volume of this triangular prism?
please help me find an equation, please explain, the equation must work for all of the number of blocks
Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.

80%
Step-by-step explanation:
percent means per 100 you have to make the denominator 100 the numerator is the percentage
you have to find the decimal
inorder to find the decimal of a fraction you devide the denominator by the number
16 ÷ 20
16/20 is as a decimal is 0.8
after finding the decimal you multiply it by 100
0.8 × 100 = 80

Write each expression without the absolute value symbol. |7-(12-x)|
The expression without the absolute value symbol is given as follows:
If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|f(x)| = f(x), x ≥ 0.|f(x)| = -f(x), x < 0.The expression for this problem is given as follows:
7 - (12 - x).
The critical value of x is obtained as follows:
7 - (12 - x) = 0
7 - 12 + x = 0
x = 5.
Hence the expression is given as follows:
If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.More can be learned about the absolute value function at https://brainly.com/question/3381225

Answer:
The answer is C. a = -4,000 m
Step-by-step explanation:
If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m
Answer:
A= -4,000m + 39,000
Step-by-step explanation:
If your doing the calculation it would be right
Given: -4,000m + 39,000
-4,000(1) + 39,000 = 35,000ft
-4,000(2) + 39,000 = 31,000ft
I don't know how to explain, but ig if you have the negative 4000, and you mutiply and add 39,000 it would decrease the ft

Answer:
D.
Step-by-step explanation:
A is incorrect because the range of the data is basically just subtraction. The range of 20-40 year old men's heart rates are higher than 50-70 year old men. B is incorrect. Think of "median" as "middle". The heart rates of the 20-40 year old men is higher than the heart rates of the 50-70 year old men. C is incorrect, because the minimum heart rate is the "starting point" of the box plot, in these cases for the 20-40 year old men, that would be 75, which is higher than the 50-70 year old men.

Alice took out an 80/20 mortgage on a $232,000 home. What is the amount
financed under the first mortgage?
Answer:
B. $185,600
Step-by-step explanation:
80/20 mortgage means pay 20% down payment and 80% finance amount of home value.
Home value = $232,000
Now, we need to find finance amount from this hone value of $232,000
Let's calculate the 80% of $232,000 as finance amount;
Finance amount = 80% of 232000
Finance amount = 0.80 x 232000
Finance amount = 185,600

Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.
