area of a circle = [tex]\pi r^{2}[/tex]
circumference =[tex]2\pi r[/tex]
Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m
we have the circumference of the inner circle which is 270.04 we can find the value of m using that
[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]
the radius of the inner circle is therefore 42.98
and the full circle has a radius off 65.02
area of shaded region = area of full circle - area of inner circle
area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]
area of shaded region = [tex]13281.39 - 5803.4[/tex]
area of shaded region = 7478 rounded off to the nearest whole number

Jada's teacher fills a travel bag with 5 copies of a textbook. The weight of the bag and books is 17 pounds. The empty travel bag weighs 3 pounds. How much does each book weigh?
Answer:
Correct
5x + 3 = 17
Step-by-step explanation:
So we need to find the book wieght only so take away the bag's weight from the total. 17-3=14. Now it says 5 books so divide 14 by 5 which is 2.8.
= 2.8 pounds

What is the point-slope form of line with slope -3 that contains the point
(10,-1)?
Answer:
D. y+1=-3(x-10)
Step-by-step explanation:
the equation for point-slope form of the line is given as y-y1=m(x-x1) where (x1,y1) is a given point, and m is the slope
we are given the point (10,-1) that passes through the line and a slope of -3
so we can substitute what we know into our equation
y--1=-3(x-10)
simplify
y+1=-3(x-10)
therefore the answer is D
Hope this helps! Good luck on your assignment!

number of goals scored
Answer:
a) 30 games
b) 66 points total
c) 2.2 points/ game
d) modal goals = 1
Step-by-step explanation:
a) 2 + 10 + 7 + 6 + 3 + 2 = 30 total games
b) (2*0) + (10*1) + (7*2) + (6*3) + (3*4) + (2*5)
0 + 10 + 14 + 18 + 12 + 10 = 66 total goals
c) 66 goals/ 30 games = 2.2 goals/ games
d) highest frequency of number of goals is 1 goal

What is the slope of (10,3) and (2,3)
Answer:
m=0
Step-by-step explanation:
the formula given for slope (m) calculated from two points is given as (y2-y1)/(x2-x1)
we are given the points (10,3) and (2,3)
label the values of the points to use for the formula:
x1=10
y1=3
x2=2
y2=3
plug into the formula
m=(3-3)/(2-10)
subtract
m=0/-8
divide
m=0
therefore, the slope is 0
Hope this helps! :D
0/-8

Answer:
x = 30
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{5}[/tex] = [tex]\frac{1}{2}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = 30
