This is a two step problem. First, you need to find the difference (or increase) in the rent using subtraction.
616-560 = $56 increase
Now we need to figure what percent 56 is to the original amount (560)
We voice it like this:
56 is to 560 as x is to 100.
The equation looks like this:
56/560 - x/100
Cross multiply to cancel out the denominators.
56 x 100 = 560 x
5600 = 560 x
x = 10 percent.
Check it!
What is 10 percent of 560?
560 x .1 = $56
Was that your increase? ... yes.
Angle BAC = (180 - 114) degrees = 66 degrees [angle on a straight line]
Angle OCA = Angle OBA = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, the measure of arc BC = (360 - 66 - 90 - 90) degrees = 114 degrees [sum of interior angles of a quadrilateral]
Angle CDE = (180 - 124) degrees = 56 degrees [angle on a straight line]
Angle OCD = Angle OED = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, the measure of arc CE = (360 - 56 - 90 - 90) degrees = 124 degrees [sum of interior angles of a quadrilateral]
Given that the measure of arc BC is 114 degrees and the measure of arc CE is 124 degrees, thus the measure of arc BE = (360 - 114 - 124) degrees = 122 degrees [angle at a point]
Angle OBF = Angle OEF = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, angle BFE = (360 - 122 - 90 - 90) degrees = 58 degrees.
For this case, the first thing we must do is define variables.
We have then:
t: number of hours
F (t): total charge
We write the function that models the problem:
Where,
b: represents an initial fee.
We must find the value of b.
For this, we use the following data:
Her total fee for a 4-hour job, for instance, is $ 32.
We have then:
From here, we clear the value of b:
Then, the function that models the problem is:
Answer:
the function's formula is:
Answer:
Volume is how much you can put in something like a box. Surface area is how much wrapping paper is needed to cover the box. Words like fill often designated volume while words like cover mean surface area.
Step-by-step explanation:
Volume is how much you can put in something like a box. Surface area is how much wrapping paper is needed to cover the box. Words like fill often designated volume while words like cover mean surface area.
