Answer:
$137.45
Step-by-step explanation:
First, we need to find the area of the circular rug in square feet.
Then we will multiply that with 1.75 to get total cost.
First,
Area of Circle =
Where r is the radius (which is half of diameter)
Given, diameter = 10 feet
Radius = 10/2 = 5 feet
Now, the area (A) :
So, total cost would be:
78.54 * 1.75/sq ft = $137.45
Answer:
E=-2
Step-by-step explanation:
Hope this helps!!!!
1 nickel = 5 cents
1 dime = 10 cents
The total = $2.40
There’s a total of 30 coins.
12 nickels = $0.60
18 dimes = $1.80
Isabelle has 12 nickels.

Step-by-step explanation:
Scientific notation:
(where and b is the power of 10 required so that the notation is equivalent to the original number)
Move the decimal point back 13 places then multiply by :
Move the decimal point back 8 places then multiply by :
Divide the total debt by the population to calculate how much each person would owe if the debt was divided equally among everyone in the US:
Apply exponent rule
(remembering that the first part "0.378" needs to be equal to or greater than 1, but smaller than 10)
Answer:
x=25.3
upper angle: 139.2
lower angle: 32.6
Step-by-step explanation:
4x+38+2x-18=180
add like terms
6x+28=180
subtract 28 on both sides
6x=152
divide by 6 on both sides
x=25.3
Upper angle:
4(25.3)=101.2
101.2+38=139.2
Upper angle= 139.2
Lower angle: 2(25.3)=50.6
50.6-18=32.6
Lower angle: 32.6
