Area of shaded portion = area of circle 1 - circle 2
Pi r*2 - pi R*2 =
Pi (r*2 -R *2 ) = 9*2 - 5*2 = (pi)81- 25= 56 x 3 = 168
Step-by-step explanation:
Simple first we will add previous balance and total deposit
498.03 + 604.28
= 1102. 31
Then we will subtract it by total withdrawals
1102.31 - 599.49
= 502. 82
The ending balance is 502.82
Answer:
y = 8 · 10ˣ
Step-by-step explanation:
y = abˣ
When x = 0, y = 8.
8 = ab⁰
8 = a
When x = 3, y = 8000.
8000 = 8b³
1000 = b³
10 = b
The function is:
y = 8 · 10ˣ
Answer:
B- The dependent variable is the amount of money she earns, and the independent variable is the number of hours she works.
Step-by-step explanation:
The amount of money she earns depends on how many hours she works, making that the dependant variable.
Answer: 139.27
Step-by-step explanation:
So let find the area of the black swuare the length is 10 and the widith is 10, using bxh the area is 100. Now let find the aea of the semi-circle. The area of a fill circle is pi radius squared so a semi circle area will be 1/2( pi radius squared). The radius is 5 so we can calculate 1/2 of 25 pi equal = 39.27. Now let add the areas: 100+39.27=139.27.
