200
Answer:
Part A.) i would say nickel and copper
Part B.) 1,034.8
Step-by-step explanation:
A.) i would say copper and nickle because they are closest in value
B.) to find the average you add all the numbers then divide them by the amount of numbers:
For example if you have 1, 3, 5 & 8
you would add 1 + 3 + 5 + 8 which equals 17
then you divide 17 by 4 which equals 4.25
Hope This Helps!!
Area of the figure
= (area of rectangle) + (area of triangle)
= (8 × 10) + (½ × 4 × 8)
= 80 + 16
= 96
Area = 96ft²
Quarts of paint needed
= 96/22
= 48/11
= 4.36
Mr. Chen will have to buy 5 quarts of paint.
Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
