Answer:

inches

Step-by-step explanation:

When you use proportions, you multiply your amount by a ratio. In the numerator, it is the unit desired while in the denominator, it is the unit that you want to cancel. In this case, you want to go from inches to centimeters. The procedure is:

20in.\frac{2.54cm}{1in} =51cm

As we can see, the units in the denominator are inches.

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

Two consecutive integers have a product of 132.Find the integers
maksim [4K]
The difference between consecutive integers is 1.
Let x = smaller integer.
Then x + 1 is the next greater consecutive integer.

x(x + 1) = 132

x^2 + x - 132 = 0

(x + 12)(x - 11) = 0

x + 12 = 0   or   x + 11 = 0

x = -12   or   x = -11

Since x is the smaller of the two integers, the answers are:
-12, -11
11, 12
There are two pairs of such integers.
