Answer:
Area of a circle=Πr²
Getting r from:
circumference of a circle=2Πr
30.1 =2(3.14)r
30.1 =6.28r
4.8 =r
Area=3.14(4.8)²
=3.14(23.04)
=72.3
The area of the circular shaped plate is given by A = 71.536 inches²
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the radius of the circular plate be r
Now , circumference of a circle is given by the formula:
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference of the plate is 30.1 inches, so we can set up an equation:
30.1 = 2πr
Solving for r:
r = 30.1 / (2π)
r ≈ 4.788 inches (rounded to three decimal places)
Now that we know the radius, we can use the formula for the area of a circle:
A = πr²
Plugging in the value of r:
A = 3.14 x ( 4.788 )²
A ≈ 71.536 inches²
Hence , the area of the circular plate is approximately 71.536 square inches

Miss Solan is buying doughnuts and coffee for her classes. The total came out to $32.12. If the coffee costs $5.96 and each doughnut is $1.09 ,how many doughnuts did she buy?
Answer:
24
Step-by-step explanation:
First, start off by subtracting the cost of the coffee ($5.96) from the total cost of $32.12. This would give you $26.16. From here, if you multiply 24 by the cost of each doughnut ($1.09) you would get $26.16 which is the total amount of money that was spent on doughnuts. Miss Solan bought 24 doughnuts.

d. What is her pace in minutes per mile?
minutes per mile___
Answer:
a) 45 minutes
b) 2 miles
c) 8 miles per hour
d) 7.5 minutes per mile
Step-by-step explanation:
a) (150/20) x 6 = 45 minutes
b) (20/150)(15) = 2 miles
c) (20/150)(60) = 8 miles per hour
d) 150/20 = 7.5 minutes per mile
Answer:
Use ratios and cross multiplication to solve this
20 miles ⇔ 150 minutesa.
20 miles ⇔ 150 minutes6 miles ⇔ x minutes20x = 150*6x = 900/20x = 45 minutesb.

C)

D)

Answer:
c and d
Step-by-step explanation:
Simplify a: 6x+7=4x+7 ~ No matter what, this cannot be possible
Simplify b: 6x=4x ~ Once again, this is impossible unless x=0, but I'll assume it can't be for now
Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c
Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.

Answer:
x = 8
Step-by-step explanation:
For the triangles to be similar then the ratio of corresponding sides must be equal, that is
[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{EF}{YZ}[/tex] , substitute values
[tex]\frac{2x-5}{22}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )
12(2x - 5) = 132 ( divide both sides by 12 )
2x - 5 = 11 ( add 5 to both sides )
2x = 16 ( divide both sides by 2 )
x = 8

Barrett is comparing the membership fees for two museums.The art museum charges a one-time fee of $8.25 plus $2.25 per month. The science museum charges a one-time fee of $10.75 plus $3.50 per month. How much does Barrett save after m months by joining the art museum instead of the science museum?
Answer:
$2.50+$1.25 times M
Step-by-step explanation:
$10.75-$8.25=$2.50
$3.50-$2.25=$1.25
$2.50+$1.25=$3.75
As only one-time fee, we cancel out it, then only add on the per-month fee, which is $1.25 every month.
The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
a. What percent of the buildings are no taller than 345 meters?
About ____
percent of the buildings are no taller than 345 meters.
Answer:
75%
Step-by-step explanation:
The answer is 75% because each point/dot, represents 25% of the data. Below 345 meters are 3 points, therefore 3 * 25% = 75%.
Approximately 75% of the buildings are no taller than 345 meters for the box-and-whisker plot.
What is the box and whisker plot?A box and whisker plot (also known as a box plot) depicts a five-number summary of a set of data: lowest, lower quartile, median, upper quartile, and maximum.
The box-and-whisker plot represents the heights (in meters) of the tallest buildings in Chicago.
We can see that all three of the data points that are less than or equal to 345 meters are included in the lower half of the box-and-whisker plot, which represents the range from the minimum to the median height.
This means 3 × 25% = 75%.
So, we can estimate that approximately 50% of the buildings are no taller than 345 meters.
