Answer:

$80\pi \frac{rad.}{sec.}$

Step-by-step explanation:

You need to calculate the circumference of this wheel to determine how far it travels with each revolution.

First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.

You need to calculate the circumference of this wheel to determine how far it travels with each revolution.

First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.

The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.

Dividing a circle’s circumference by pi will give you a circle’s diameter.

Multiplying a circle’s diameter by pi will give you a circle’s circumference.

Joel earns $5.50 an hour and time-and-a-half for overtime. how much does he earn for a 44.5-hour week?

vova2212 [387]

The expression which can be used to solve this problem is 5.50h + 1.5h.

Since the given data is 44.5 hour week, all we need to do is substitute the given data to the expression. Since it takes 56 hours a week for a complete office/working hour without overtime, Joel's 44.5 hour week means he did not have overtime hours. Therefore the solution is,

5.50(44.5) = 244.75 Dollars.

A woman bought 210 oranges for $6.50. She sold all of them at 3 for 20cents. How much profit did she make?

Dafna11 [192]

Divide total bought by 3 and multiply by 20cents:

210/3 = 70

70 x 0.20 = $14.00

Subtract the amount they paid by the amount they made:

14.00 - 6.50 = $7.50

The profit made was: $7.50

A word processor that was purchased for $600

klasskru [66]

The slope of the graph shows the rate of change, or, in this case, the rate of depreciation, which you are told is $100 per year. So, depending upon the units used in your graph, the slope will be 100/1, and since it is a decrease as the years increase, it will have a negative slope, i.e. -100/1.

Or, if you had drawn your graph with units of $100 dollars on the y-axis, then you might say that the slope was -1 / 1.

The corresponding formula would of course be

y = 600 - 100t

where y = value after t years, and (if you are into calculus) differentiating would give you

slope = dy/dt = -100
