Answer:
22.2 cm
Step-by-step explanation:
First, find the area of the larger circle.
50.2 x 2.5 = 125.5
Now, we need to find the diameter of the larger circle. We have the area, so we can plug this value into the formula of the area of the circle to find the diameter.
A = pi • r^2
125.5 =3.14 •r^2
122.36 = r^2
r = 11.1
Since radius is half the diameter, multiply r by 2.
11.1 x 2 = 22.2 centimeters

Samantha is collecting quarters for a school fundraiser. She wants to wrap what she has already collected into coin rolls. Each coin roll holds 40 quarters. If Samantha has 479 quarters, how many coin rolls will she need?
Answer:12
Step-by-step explanation:
Given
Each coin roll can hold 40 quarters
There are a total of 479 quarters
So, no of coin roll [tex]=\dfrac{\text{Total quarters}}{\text{Holding capacity of each coin roll}}[/tex]
[tex]\Rightarrow \frac{479}{40}=11.975[/tex]
As no of coin rolls cannot be in decimal
[tex]\therefore[/tex] there are 12 coin rolls

Rick is buying $115 tennis racket from a sporting good store. If the racket is on sale for 35% off in sales tax is 8% how much will he pay in total
Answer:
$80.73
Step-by-step explanation:
First, find 35% of 115.
35% as a decimal is 0.35 (35/100)
0.35 x 115 = 40.25
Now, subtract 40.25 from 115.
115 - 40.25 = 74.75
Now, to find the sales tax, find 8% of 74.75.
8% as a decimal is 0.08 (8/100)
0.08 x 74.75 = 5.98
Now, subtract add 5.98 to 74.75
5.98 + 74.75 = 80.73

its a sqaure so the angles are 90 degress each.
90 - 38 = 52
answer: C. 52
Answer:
c = 52*
Step-by-step explanation:
If we assume that both shaded triangles are equivalent, and we know that the total angle of a square's corner is 90*, to find the missing angles of the unshaded area (angle z) we just subtract 38 from 90.
90 - 38 = 52*.

Yesterday, Ian walked 2/3 of a mile. Today, he walked 1/5 of a mile. How far did he walk altogether?
Answer:
1.4km
Step-by-step explanation:
2/3 + 1/5
Find the LCM of the denominators
(5x2)+(3x1)/15
Clear brackets:
5x2=10
3×1=3
Therefore, we have
10+3/15=13/15
In total, he has walked 13/15 of a mile
1 mile is 1.609344 km
Therfore, he walked 13/15×1.609344 km=1.4km approximately.
OR
2/3 of 1mile is 2/3×1.609344 km
=1.07km
1/5 of 1 mile the next day is 1/5×1.609344 km
=0.32km
Total distance 1.07+0.32=1.39 approximately 1.4km
Ian walked 13/15 miles altogether.
What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
Yesterday, Ian walked 2/3 of a mile.
Today, he walked 1/5 of a mile.
To find the number of miles, he walks altogether:
The sum of both the fractions,
2/3 + 1/5
= (2 x 5 + 3 x 1) / 15
= (10+3) / 15
= 13/15
Therefore, he walks 13/15 miles.

Ms. Mor ris has 35 tests to grade this weekend. Mrs. Cook has 80% more tests than that to grade this weekend. How many tests does Mrs. Cook have to grade?
Answer:
Mrs. Cook has to grade 63 tests.
Step-by-step explanation:
In order to find the answer, first you have to calculate 80% of the number of tests Ms. Morris has:
35*80%= 28
Then, you have to add the number that represents 80% to the number of tests Ms. Morris has to grade:
35+28=63
According to this, the answer is that Mrs. Cook has to grade 63 tests.

In a class A of 25 students, 20 passed in first class; in another class B
of 30 students, 24 passed in first class. In which class was a greater
fraction of students getting first class?
Answer:
class A 20/25 = 4/5
class B 24/30 = 4/5
they are both the same
Answer:
Both classes have the same fraction (80% or 4/5).
Step-by-step explanation:
20 is 4/5 of 25, so 80% of students in Class A passed in first class.
24 is 4/5 of 30, so 80% of students in Class B passed in first class.
Both 20/25 and 24/30 simplify to 4/5, or 80%, so both classes have the same fraction of students passing.

2. how are the center, radius, and a point on the circle expressed algebraically?
Answer: 1. What are the focus and directrix of a parabola? Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).
2.The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle.

6 squared + b squared = 24 squared solve for B
Answer:
b = 6√15
Step-by-step explanation:
6² + b² = 24²
36 + b² = 576
b² = 540
b = √540
b = √9 · √60
b = 3 · √60
b = 3 · √4 · √15
b = 6 √15
