Answer: 2√14
Step-by-step explanation:
The area of a circle is A = πr², where r is radius. Since the area is 56π, we can divide π from both sides to find r² = 56. The square root of 56 is √56, which can be rewritten to √8×√7. The square root of 8 is equal to 2√2, so the simplified value for radius is 2√2×√7, or 2√14.
The trapezoid shown above has an area of 21.66 square inches.
What is the total area of the shaded sections of the trapezoid?
A. 2.09 square inches
B. 4.18 square inches
C. 4.86 square inches
D. 8.74 square inches
Answer:
2.09 for only one triangle.
4.18 for two triangles.
Step-by-step explanation:
Hope this helps good luck in math if you need to look up how to find the area of a triangle all you have to do is multiply the base times the height then divide it by two.

You have the following coins in your pocket: 5 quarters, 6 dimes, 2 nickels, and 12 pennies. What is the probability you will draw a dime and then a
penny?
5 quarters is 125 cents 6 dimes is 60 cents 2 Nickels are 10 cents and 12 pennies are 12 cents all that in total is 207
Probability is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability of drawing a dime and then a penny is 9/50.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of coins = 6 dimes + 2 nickels + 12 pennies = 20
Number of dims = 6
Number of nickels = 2
Number of pennies = 12
The probability of drawing a dime.
= 6/20
= 3/10
The probability of drawing a penny.
= 12/20
= 6/10
= 3/5
Now,
The probability of drawing a dime and then a penny.
= 3/10 x 3/5
= 9/50
Thus,
The probability of drawing a dime and then a penny is 9/50.

(Side)2 = 484
side of a square = 22 m
According to the question,
circumference of a circle = perimeter of a square
2∏r = 4 × 22

A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?
ASAP HELP
Answer:
Step-by-step explanation:
21x.30=6.3
21-6.3= 14.7
If shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that a shirt cost is $21 last month.
The price decreased by 30% in this month.
We have to find the new price.
To find this we have to find 30 percentage of 21.
Convert 30 % to decimal value by dividing with 100 and then multiply the decimal value with $21.
30/100× 21
0.3×21
$6.3
So the amount decreased is $6.3
The new price we get by subtraction $6.3 from $21.
21-6.3
New price = $14.7
Hence, if shirt cost $21 last month and the price decreased by 30% then the new price is $14.7.

How do you find the mean, median, mode, and range of a set of numbers?
Answer:
You find the mean by adding all the numbers together then divide the sum of that by the amount of numbers there are. You find the median by looking at the middle number. You find the mode by looking at the most used number. You find the range by subtracting the highest and lowest numbers.
Step-by-step explanation:
say you have these numbers ( 8, 7, 17, 12, 0, 9, 11, 5, 8)
Mean:
8 + 7 + 12 + 17 + 0 + 9 + 11 + 5 + 8 = 77
77 ÷ 9 = 8.5
Median: 0
Mode: 8
Range: 17 - 0 = 17
Answer:
median is the middle number
but if the are two numbers in middle u add those two n divide by 2
range is the biggest number subtract lowest number
mean is total average divide by the number of data
mode is the number that appears many times

What’s the length of the hypotenuse in inches?
Answer:
The hypotenuse is 25 inches.
Step-by-step explanation:
This is a right triangle, so the Pythagorean Theorem applies.
I will assume you know about the Pythagorean Theorem, therefore I will not define it.
Here, I am solving for the hypotenuse.
[tex]a^2+b^2=c^2[/tex]
[tex]24^2+7^2=c^2[/tex]
[tex]576+49=c^2[/tex]
[tex]625 = c^2[/tex]
[tex]25=c[/tex]
Answer:
25
Step-by-step explanation:
To find the hypotenuse, you need to use a^2+b^2=c^2
Plugging the numbers in, the equation is
24^2+7^2=c^2
From here, you can just solve the equation, simplifying it equals
576+49=c^2
Add the two values
625=c^2
from here, you would square both sides to get c standing alone. This results in the equation finishing with the answer:
25=c
or flipping it around to make sence
c=25

Joanne and Roger are planting a rectangular garden. The garden is 7 ft by 13 ft. They want to use half of the garden for
tomatoes and half of the garden for cucumbers. They decide to separate the garden into two right triangles as shown. What is
the area of the cucumber part of the garden?
Answer:
45.5 ft^2
Step-by-step explanation:
The area of the garden is (7 ft) by (13 ft), which works out to 91 ft^2.
The half garden used for cucumbers is (91 ft^2)/2, or 45.5 ft^2.
