Answer:
An=67⋅0.92n
Step-by-step explanation:
The solution is, the formula found in the given question is ,
An=67. 0.92n.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
given that,
At 12 p.m., the number of cars in a parking lot is 67.
It is estimated that the number of cars in the parking lot will decrease by 8% each hour.
so, we get,
Given,
at first the number of cars in a parking lot is = 67
now, it is decreasing by 8% each hour.
So, for any hours , let after 'n' hours,
the number will be = 67 * (100 - 8)%×n
=67 * 92%×n
= 67* 0.92n
Thus, The solution is, the formula found in the given question is ,
An=67. 0.92n.

Help please !
A rectangular paperboard measuring 22 in long and 14 in wide has a semicircle cut out of it, as shown below.
Find the area of the paperboard that remains. Use the value 3.14 for pi, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
231.07 in^2
Step-by-step explanation:
The radius of the semicircle is 14/2 = 7 in
22x14 - 3.14x(7^2)/2 = 231.07 in^2
Answer: 231.07 m^2
Step-by-step explanation:
Area of the remaining paperboard = Area of the entire paperboard - Area of semicircle
1. area of paperboard = l*b = 22*14 = 308 m^2
2. area of semi circle = 1/2 pi r^2 = 1/2*3.14*49/2
Therefore, area of remaining paperboard = 231.07 m^2
What value of y makes the equation true?
-7/12 = y/-36
A -21
B 28
C -28
D 21
Answer:
D) 21
Step-by-step explanation:
y= -7/12× -36
or, y= -7×-3
or, y= 21
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{-7}{12}[/tex] = [tex]\frac{y}{-36}[/tex] ( cross- multiply )
12y = 252 ( divide both sides by 12 )
y = 21 → D

Also can you explain how you got your answer
Answer:
The answer is c! 7,36,60,30
Step-by-step explanation:
To answer this equation you have to find a number that fits the description of what is required. It may seem difficult but it's not first off it's trial and error you have to find the right equation for every given number. For example, what makes 15 equal 5 true? To make the equation true you have to do 15 divided by 3 equals 5 now we take the / 3 and apply them to all the other numbers so 21 / 3 is 7 , 36 divided by 3 is 12 hi, 60 / 3 is 20 , 90 /3 is 30. If you have any other question like this all you have to do is trial and error with a number to make the equation true hopefully that helps! (B.t.w / symbol means divided by)

Fred's car can travel 36.8 miles on one tank of gas. His gas tank holds 16 gallons. How many miles can Fred's car travel per gallon?What is the solution of the equation below? x+8.63=11.001
Answer:
Answer to Question 1: 2.3 miles per gallon
Answer to Question 2: x = 2.371
Step-by-step explanation:
Question 1 (explanation): 36.8 (miles on one tank of gas) / 16 (gallons of gas that Fred's car hold) = 2.3 (miles that Fred's car can travel per gallon)
Question 2 (explanation): 11.001 - 8.63 = 2.371

48 is 12% of what number?
Answer:
I'm not sure but from my calculations,it is 400
Answer:
400
Step-by-step explanation:
In order to find out a percentage of something you divide the percent by 100 (12/100) to get a decimal, which would be 0.12. Now with this we already know 12% of something is 48 and in order to find what we took 12% from we divide 48 by 0.12.
48÷0.12 or 48/0.12 = 400

What is the sale price of a bag of potato chips priced 4 and the sale 25% off?
A:$1.50 B:$2 C:$3 D:$2.50
Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3
Hope that helps!

$59.75 camera, 4% sales tax
please show in full detail
Answer:
The total cost would be: $62.14
Step-by-step explanation:
First convert the percent to a decimal, so since it is 4%, you move the decimal two places to the right, so it would be .04.
Next, multiply $59.75 x .04%. This equals $2.39.
Then, take the product and add it to $59.75. So, $59.75 + $2.39.
This equals $62.14!
A classroom is arranged with 6 seats in the front row, 8 seats in the middle row, and 10 seats in the back row. The teacher randomly assigns seats to students as they enter the classroom.
What is the probability that the first student who enters the classroom will be assigned a seat in the front row?
Answer:
[tex] \frac{6}{24} \: or \: 0.25 \: or 25\%[/tex]
Step-by-step explanation:
First add them all up to get the total amount of seats.
6+10+8=24
there are 6 seats in the front row. so that means it will be
[tex] \frac{6}{24} [/tex]
24÷6=0.25
0.25×100=25%

Answer:
3. One Solution. (0,4). (they have different slopes and y-intercepts)
The solution can be found using elimination method:
Add the equations together
y = -x + 4
y = x - 4
2y = 0
y = 0
Solve for x
0 = x - 4
x = 4
(4, 0)
4. No solution
x + y = -2 and 3 which is not possible

What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°
