Answer:
3π units
Step-by-step explanation:
The full circumference of a circle with radius 2 is ...
C = 2πr
C = 2π(2) = 4π
The arc shown is 3/4 of the full circle circumference so is ...
3/4C = (3/4)(4π) = 3π . . . units
Answer:
-6-6x<6-30x
Step-by-step explanation:
step 1 -1(6+6x) would be -6-6x
step 2 the other side
6(1-5x) would be 6-30x
sorry if im wrong
Answer:
(x-7)²+(y+5)²=25
Step-by-step explanation:
The standard form of a circle is (x-h)²+(y-k)²=r²
(h,k) is the center
r is the radius
h=7
k=-5
r=5
(x-7)²+(y--5)²=5²
(x-7)²+(y+5)²=25
We just need to make the fractions equivalent, if you take 3/5 and put it in tenths you get 6/10. Which means that the oldest brother has 6/10 the youngest has 1/10 and because we can add those two together and subtract from the total we get the middle brothers amount, 3/10 of the money. Multiply the fractions by the 108 total to get the amount of money that each person has.
6/10*108=64.8
3/10*108=32.4
1/10*108=10.8
To make sure the answers are correct add the values together. 64.8+32.4+10.8=108
The eldest brother has $64.80, the second eldest has $32.40 and the youngest has $10.80.
