Hence -2 to the 4th power is equal to 16
the length of a rectangle is 2 inches less than 3 times it width . The perimeter of the rectangle is 124 inch. WHat is the length of the rectangle
Step-by-step explanation:
let w = width
length = 3w-2
perimeter = 2*length + 2*width
perimeter = 2(3w-2) + 2w
perimeter = 6w - 4 + 2w
perimeter = 8w - 4
perimeter = 124 inch
8w - 4 = 124inch
+4 to each side
8w = 128inch
divide each side by 8
w = 16
length = 3w-2
= 3(16) - 2
length = 46 inch

What is the value of x?
x = 25
x = 180
x = 135
x = 20
Answer:
x=20
Step-by-step explanation:
Since all the angles in any give triangle adds up to 180, we can make an equation from this geometry question. x+5+7x-5+x=180 (Adding all the angles). If you simplify this, it becomes 9x=180, or x=20.
Bonnie's doctor recommended that she drink 2cups of milk per day. If she buys 3 quarts of milk,will it be enough milk to last 1 week?
Answer:
She does not have enough milk to last for 1 week
Step-by-step explanation:
From the question, we are told that:
Bonnie's doctor recommended that she drink 2cups of milk per day.
Step 1
The number of days in a week is 7 days
Hence
1 day = 2 cups of milk
7 days = x
Cross Multiply
x = 7 × 2 cups of milk
= 14 cups of milk.
Step 2
If she buys 3 quarts of milk,will it be enough milk to last 1 week?
We have the conversion rate as:
1 quart = 4 cups
Therefore,
1 quart = 4 cups
3 quarts = x cups
Cross Multiply
x cups = 3 quarts × 4 cups/1 quart
x cups = 12 cups of milk
This means she bought 12 cups of milk.
Therefore, from the above calculation, she does not have enough milk to last for 1 week because due to her doctor's recommendation, she need 14 cups of milk for the week but she only bought 12 cups of milk

Plan A $17 plus 0.10 for each min of calls. Plan B &13 plus an additional 0.15 for each min. What amount do the two plans cost the same?
Answer:
80 minutes ; $25
Step-by-step explanation:
Let x = number of minutes
Plan A :
17 + 0.1x - - - (1)
PLAN B :
13 + 0.15x - - - (2)
Both plans will cost the same when ;
17 + 0.1x = 13 + 0.15x
Solve for X
0.1x - 0.15x = 13 - 17
-0.05x = - 4
divide both sides by - 0.05
-0.05x / - 0.05 = - 4 / - 0.05
x = 80 minutes
Amount :
17 + 0.1(80) = 17 + 8 = $25

simplify and leave answer in decimal form (3,6×10 to the power 6)-(5,2×10 to the power 5 show steps of calculations
Answer:
3.08×10 to the power of 4
Step-by-step explanation:
3.6×10the power of 6 =3,600,000
and 5.2× 10 to the power of 5 = 520,000
then the next step is to substract
3,600,000-520,000=308,000
then when we change it to decimal place we will get=3.08×10 to the power of 5

A Camera has a list price $560.99 before tax if the sales tax rate is 7.75% find the total cost of the camera wit sale tax included round your answer to the cent
Answer:
$604.47
Step-by-step explanation:
Given data
Cost of camera= $560.99
Tax= 7.75%
Let us find the amount of the tax
=7.75/100* 560.99
=0.0775*560.99
=$43.48
Hence the amount of the tax is $43.48
Therefore the total cost is
=43.48+560.99
=$604.47
