74.3 is greater because it is 10 times greater than 7.43.

Perhaps the question will be less confusing if you temporarily ignore the decimal parts, and just compare the whole-number parts.

Look at  74 , and then look at  7 .
Look at them again, and a few more times if necessary.
You'll see that  74  is waaay bigger than  7 .

That's true even when you stick the decimal parts back on.
The decimal parts can't change it ... a decimal part can't
add more than ' 1 ' to a whole number.

So 74 (plus any decimal) is still waaay bigger than 7 (plus any decimal).

two high school students are hired to rake leaves. They will work a couple hours each afternoon until the job is completed. They
Schach [20]

Answer:

x = 14 days

Step-by-step explanation:

To answer the question, find a function that represents the payment mode of plan A and an equation that represents the mode of payment of plan B.

For Plan B the payment is constant every afternoon, $ 11.5 (or 1150 cents) so the equation to represent this form of payment is as follows:

A = 1150x (with units in cents)

This equation represents the line of a line of slope 1150, which passes through point (0,0). Where x is the number of days {1, 2, 3 ....}

In form of payment B, the amount of payment is doubled each day. And the first payment is 2 cents. Therefore this model is represented by an exponential base 2 equation of the form:

B = (2) ^ x

Where x represents the number of days, which is always greater than 0 {1, 2, 3, 4 ...}

To know in which day the salary will be approximately the same we equate both equations and we clear x.

A = B

1150x = (2) ^ x\\1150x- (2) ^ x = 0

It is a somewhat difficult equation to solve, so I recommend iterating to get a value where the function approaches 0 (when this difference is zero it means that the A and B salaries are the same).

Suppose

x = 13 days

1150(13) - (2) ^ {13} = 6758cents

It is not equal to 0.

Let's try with x = 15

1150(15) - (2) ^ {15} = -15518 cents

Then the value that makes the function zero is between x = 13 and x = 15

Let's try with x = 14

1150(14) - (2) ^ {14} = -284 cents = 2.84 $ difference. X = 14 is the whole number where functions A and B are closer together (the salary is approximately the same). Therefore the answer is

x = 14 days

Find the area of the shaded region.
olasank [31]
Area of the big triangle (shaded area and small tris for below) is 36 * 51 divided by 2 (area of triangle is base * height over 2). this would give you 918.

area of the small triangle below is 51 * 11 divided by 2 (see above), which is 280.5.

shaded shape area is the big triangle shape minus the small triangle below, which is 918-270.5, which is 637.5 units.
