In the diagram, the radius of the outer circle is 2x em and the radius of the inside circle is 6 cm. The area of the shaded region is 220 cm? What is the value of x2
Answer:
Answer: 8 (second choice)
Step-by-step explanation:
Area of a Circle
Given a circle of radius r, the area is calculated by the formula:
[tex]A=\pi\ r^2[/tex]
There are two circles in the diagram. The outer circle has a radius of r1=2x, thus its area is:
[tex]A_1=\pi\ (2x)^2[/tex]
The interior circle has a radius of r2=6 cm, thus its area is:
[tex]A_2=\pi\ 6^2=36\pi[/tex]
The shaded area is obtained by subtracting A1-A2:
[tex]A=\pi\ (2x)^2-36\pi[/tex]
The value of the shaded area is given as 220π cm2. Equating:
[tex]\pi\ (2x)^2-36\pi=220\pi[/tex]
Dividing by π:
[tex](2x)^2-36=220[/tex]
Adding 36:
[tex](2x)^2=220+36=256[/tex]
Taking square root:
[tex]2x=\sqrt{256}=16[/tex]
Dividing by 2:
x = 8 cm
Answer: 8 (second choice)

Jasmine has 50 marbles in a bag. 20% of the marbles are blue. How many marbles are not blue? Explain how you found your answer.
Answer:
20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
WOW, that's a lot of points!!
To find the answer for this problem, you take 80% of 50.
In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Reggie is deciding when to go bowling with his friends. Friday night is glow-bowling night,
with 5 glow-bowling games for $22.50. But the early-bird special on Saturday morning offers
8 games for $30. How much more does glow-bowling cost per game?
Answer:
glow bowling costs $0.75 more per game
Step-by-step explanation:
1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50
2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75
3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
4.50-3.75=0.75
Answer: The answer is 0.75

Answer:
Step-by-step explanation:
1. x^2-x-20=3x-15
x=5, x=1 substitute
y=3*5-15 = 0
y=3*(-1)-15 = -18
Solution: (5,0) & (-1,-18)
2. x^2+2x+3=x+5
x=-2, x=1 substitute
y= -2+5 = 3
y=1+5 = 6
Solution: (-2,3) & (1,6)
Divide.
