8 - 3(7-4y)
8 - (3x7 - 3x4y) You need to develop between parentheses bcs there is a minus between 8 and 3.
8 - (21 - 12y)
8 - 21 + 12y /!\ A minus before parentheses changes the sign in the parentheses !
12y - 13

What is the area of a circle. Using 3.14 for. A circle with diameter of 8.4 ft.
ira [324]

Hey there! I'm happy to help!

First, let's find the radius. The radius is half of the diameter.

8.4/2=4.2

Here's how to find the area of a circle.

Square the radius.

4.2²=17.64

And multiply by pi (3.14 in our case)

17.64(3.14)=55.3896

We round to the nearest tenth, giving us an area of 55.4 ft²

Have a wonderful day! :D

Our bill was $5.79. Avon has a 5.25% tax and our waitress earned a 15% tip. What was the total bill?
oksano4ka [1.4K]

Answer:

$6.96

Step-by-step explanation:

5.25% of $5.79

5.79 × 5.25/100 = $0.303975 or $0.30

15% of $5.79

5.79 × 15/100 = $0.8685 or $0.87

total

$0.29 + $0.87 + $5.79 = $6.96
