area of circle :- π r²
[tex] \frac{22}{7} \times 3 \times 3 \: ft {}^{2} \\ \frac{22}{7} \times 9 {ft}^{2} \\ \frac{198}{7} = 28.26 {ft}^{2} [/tex]
Answer:
A.
Step-by-step explanation:
The formula (i believe) is:
A = 2r[tex]\pi[/tex]
A = 2(3)(3.14)
A = (6)(3.14)
A = 18.84
The answer i got is 18.84

Zoe has a circular shaped rug on her bedroom floor. The diameter of the rug is 8 feet. What is the circumference of the rug?
6.28 feet
12.56 feet
25.12 feet
50.24 feet
Answer:
25.12
Step-by-step explanation:
circumference is 2 x π x r or π x d
so 8 x π would give you 25.12
Answer:
C.
Step-by-step explanation:
The formula for the circumference is:
C = [tex]\pi[/tex]d
C = (3.14)(8)
C = 25.12
The circumference of the circular shaped rug would 25.12 feet.

Answer:
c) (-3s) - 9
Step-by-step explanation:
(-5s) + 2s - 9
-5s + 2s - 9 <== combine like terms
-3s - 9
Therefore, our answer is c.
Hope this helps!
Answer:
the answer is C.
Step-by-step explanation:
Start by combining like terms (-5s) and 2s= (-3s)
You can't subtract 9 from this because they aren't like terms.
(-3s) -9

Answer:
x=1
Step-by-step
Step 1:
Simplify x/x2
Dividing exponential expressions :
1.1 x1 divided by x2 = x(1 - 2) = x(-1) = 1/x1 = 1/
Equation at the end of step 1:
2 1 1
(((—+1)-—)-1)-((2•—)-1) = 0

STEP 2:Rewriting the whole as an Equivalent Fraction:
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using x as the denominator :
1 1 • x
1 = — = —————
1 x
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2 - (x) 2 - x
——— = ———

When a fraction equals zero :
9.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-1
——— • x = 0 • x
x
Now, on the left hand side, the x cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-1 = 0
.2 Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1
One solution was found :
x = 1

help! how do i find the slope and the y-intercept? please help
Answer:
1 is the - Slope
4 is the y-intercept
Step-by-step explanation:
To find slope, you have to use two points and use the formula [tex]\frac{y2-y1}{x2-x1}[/tex]
Here one point is (2,6), and other point is (4,8)
Substitute to get [tex]\frac{2}{2}[/tex] which equals 1.
To find y-intercept, x should be 0. If x is 0 then why in this case would be 4

Answer:
390m^2
Step-by-step explanation:
The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area
a = 5m
b = 12m
c = 13m
L = 11m
First, we need to find the base area...
base area = (a*b)/2
(5*12)/2 = 30 m^2
Next, find the surface area
A = 11(5 + 12 +13) + 2*30 = 390 m^2

Answer:
hee-hee!
Step-by-step explanation:
We know that the circles diameter is 15 mm. We can tell that by looking at the side of the rectangle. It says 15 mm.
Either way, we use the formula to find the area of a circle:
A = [tex]\pi[/tex]d
A = (3.14)(15)
A = 47.1
The area of the circle is 47.1. (i think?)
sowwy if it took long
Answer:
426.45 mm
Step-by-step explanation:
find the area of the circle by multiplying the radius by pi(3.14) then you would subtract that from the area of the rectangle. Hope this helps
A square scarf has a side length of 3/4 yard on each side.
What is the area of the scarf?

Andrew scores 79, 86, 63, and 82 on his recent tests, when measure of centeral tendency should he use to describe to his mom his his tests are going
Answer:
e
Step-by-step explanation:
Central tendency means “the statistical measure that identifies a single value as representative of an entire distribution." These measures include mean, median, and mode.
Andrew scores 79, 86, 63, and 82 on his tests.
63, 79, 82, 86
Mean: 79 + 86 + 63 + 82 = 77.5 or
Median: 79 + 82 = 80.5
(you have to add these numbers bc there is no exact median as none are repeating)
Mode: There is no exact mode since there is no repeating numbers.
He should use the mean bc the mean is a pretty good number.
I'm not sure if you would want to tell your mother that you're barely getting an average. or higher than failing.
either way, hope this helps :)

Answer:
1) 0.392
2) 0.395
3) 0.397
4) 0.393846294629468261456382648477982195862
Step-by-step explanation:
It is asking for 3 numbers greater than 0.39, with three in the tenth place (0.x000) that is less than 1. By adding a number in the thousandth place to 0.39, we automatically make it larger. Adding more digits will make it slightly larger, as long as it isn't a 0. All 4 answers I have provided are correct, however, I would just use the first 3 for your question.

Ryan has a bag that contains strawberry chews, cherry chews, and watermelon chews. He performs an experiment. Ryan randomly removes a chew from the bag, records the result, and returns the chew to the bag. Ryan performs the experiment 37 times. The results are shown below:
A strawberry chew was selected 8 times.
A cherry chew was selected 12 times.
A watermelon chew was selected 17 times.
Based on these results, express the probability that the next chew Ryan removes from the bag will be cherry or watermelon as a decimal to the nearest hundredth.
Answer:
32.43%
Step-by-step explanation:
Since there are a total of 37 tests and cherry was selected 12 times, the probability would be 12/37.
12(100/37)
32.43
The probability that it will be a cherry or watermelon is; P(Cherry or water melon) = (12 + 17)/37 = 0.51
How to find the Probability?
We are told that Ryan performs the experiment a total of 37 times.
From the experiment he got;
Strawberry = 8 times
Cherry = 12 times
Watermelon = 17 times
Thus, probability that it will be a cherry or watermelon is;
P(Cherry or water melon) = (12 + 17)/37 = 0.51
