The average time it takes to travel from home to school is 22 ½ minutes. Depending upon weather and morning traffic, the actual
Art [367]

Answer:

17 \le t \le 28

Step-by-step explanation:

Given

t = 22\frac{1}{2} --- average time

\triangle t = 5\frac{1}{2} --- the variation

Required

The inequality to represent the scenario

To do this, we simply add and subtract the variation from the average time.

i.e.

t \± \triangle t

So, the inequality is:

22\frac{1}{2} - 5\frac{1}{2} \le t \le 22\frac{1}{2} + 5\frac{1}{2}

Solve:

17 \le t \le 28

Decrease 340 minutes by 10%
Anvisha [2.4K]
Hey there,

To do this you need to work bout what 10% of 340 minutes is.
To do this do 340 / 10 = 34
34 is 10% of 340.
Now you should subtract the 10% from the original time.
340 - 34 = 306.
The answer is 306 minutes.

That was the long method. The short method is to use percentage multipliers.
To do this you do 340 x 0.9 = 306.

Either way you would get the same answer of 306 minutes.

Hope This Helps You!
Good Luck Studying :)

suppose the function g determines the perimeter of the rectangle (in inches) given a number of seconds, t , since the rectangle
jasenka [17]

the perimeter of a rectangle is equal to 2L + 2W.

the perimeter of the rectangle is represented by P.

P = 2L + 2W

when W is fixed at 8, the perimeter of the rectangle becomes P = 2L + 16

A)Write a formula that expresses the length of the rectangle in inches, l, in terms of the number of seconds t since the rectangle began growing.

time in seconds is represented by T.

the length of the rectangle increases by 2.4 inches every second.

L = 2.4 * T

B)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the length of the rectangle in inches, l.

P = 2L + 16

C)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the number of seconds t since the rectangle began growing.

P = 2 * 2.4 * T + 16 which becomes P = 4.8 * T + 16

D)Suppose the function g determines the perimeter of the rectangle in inches given a number of seconds t since the rectangle started growing. Write a function formula for g.

g(T) = 4.8 * T + 16

when T = 0, the perimeter of the rectangle is equal to 0 + 16 = 16.

when T = 1, the perimeter of the rectangle is equal to 4.8 + 16 = 20.8.

when T = 2, the perimeter of the rectangle is equal to 9.6 + 16 = 25.6.

etc...

keep in mind that the formula for the perimeter of the rectangleis P = 2 * L + 2 * W.

W is always 8, so the formula becomes P = 2 * L + 16.

L is equal to 2.4 * T, so the formula becomes P = 2 * 2.4 * T + 16.

after simplification, the formula becomes P = 2.8 * T + 16.

the complete question is

A rectangle has a fixed width of 8 inches and a length of 0 inches. The length of the rectangle then begins increasing at 2.4 inches per second.

A)Write a formula that expresses the length of the rectangle in inches, l, in terms of the number of seconds t since the rectangle began growing.

B)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the length of the rectangle in inches, l.

C)Write a formula that expresses the perimeter of the rectangle in inches, P, in terms of the number of seconds t since the rectangle began growing.

D)Suppose the function g determines the perimeter of the rectangle in inches given a number of seconds t since the rectangle started growing. Write a function formula for g.
