Answer:

The area of the circle is 113.0 ft²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 6ft

π = 3.14

a = π * r²

we replace with the known values

a = π * (6ft)²

a = π * 36ft²

a = 113.04ft²

The area of the circle is 113.04ft²

round to the nearest tenth

a = 113.04ft² = 113.0 ft²

weeeeeb [17]

Hello,

to find the total cost (c) of the colored strips we have to multiply the number of strips (n) by the cost of each color strip (99¢), that as an algebraic function is:

$\boxed{c= n*99}$ [¢]

Now, if we use 3 solid color strips, that means that we use 4 patterned strips, so:

$Cost=3*0.99+4*1.25 \\ \boxed{Cost= 7.97}$

Answer: c=n*99 and Cost per curtain= $7.97

Q # 11 please help to resolve

Fofino [41]

It is the fourth choice - 1/4.

There are five odd number out of the ten number they are choosing from.
The probability that Jason will choose an odd number is 5/10 = 1/2
The probability that Kyle will choose an odd number is 5/10 = 1/2
Multiply the two probabilities to get the probability of them choosing odd numbers.
1/2 * 1/2 = 1/4

We can do S=1/2 of (4x+2)+4 * (3x+1) +4. All we are doing is adding 4 feet. I believe you are able to simplify it to 1/2 of 4x+6 * 3x+5
