What expression can be used to calculate the rate per minute at which the air freshener dispenses sprays?
Answers
You didn't give any answers, but, I hope this will help you out a bit:
for example, if the air freshener sprays 3 times every 20 minutes,
here are our points:
(20,3), (40,6), (60,9), (80,12)
lets take the second and third point to find the slope.
3/40 would be the slope.

Answer: 1/3
Step-by-step explanation:
To add fractions with different denominators, we first need to find a common denominator. In this case, the common denominator is 12.
11/12 + (-7/12) = (11 - 7) / 12
Simplifying the numerator gives us:
4/12
We can further simplify by dividing both the numerator and denominator by their greatest common factor, which is 4.
4/12 = 1/3
Therefore, 11/12 + (-7/12) = 1/3.

1. You have that the formula for calculate the area of a triangle is:
A=bh/2
Where A is the area of the triangle, b is the base of the triangle and h is the height of the triangle.
bh/2=124
bh=124x2
bh=248
2. The problem asks for the new area of the triangle if its base was half as long and its height was three times as long. Then, you have:
Base=b/2
Height=3h
3. Therefore, when you substitute this into the formula for calculate the area of a triangle, you obtain:
A'=bh/2
(A' is the new area)
A'=(b/2)(3)/2
A'=3bh/4
4. When you substitute bh=248 into A'=3bh/4, you obtain:
A'=186 units²
The answer is: 186 units²
a. y=−12x−6
b. y=2x+1
c. y=−12x+5
d. y=12x−3

when a fraction is being divided by a number you multiply the first number by the reciprocal of the second number. A reciprocal is basically a number that can be multiplied by the first number to make 1
So in this case the reciprocal of 5 is 1/5
now just multiply and get 1/25
So the answer is 1/25
The first number is already a fraction; make the second whole number into a fraction.
Now follow these steps:
Rewrite equation.
Switch division sign to multiplication.
Find reciprocal of the second fraction, which means to flip the fraction around.
Cross multiply.
Simplify if needed.
Now let's put that into this equation.
The unit rate is calorie(s) per cup.

Answer:
23.142857143 calories or 23 1/7 calories
The unit rate is calories per cup
Step-by-step explanation:
7- cup serving = 81 calories
2 cups = x calories
Cross Multiply
2 cups × 81 calories = 7 cups × x
x = 2 cups × 81 calories/7 cups
x = 23.142857143 calories or 23 1/7 calories
