Answer: 3,892,314 CDs
Step-by-step explanation:
You can find this using the future value formula:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = 29,000,000
Rate = -20% because it is decreasing
Number of years = 9
CDs sold in 9 years will therefore be:
= 29,000,000 * ( 1 - 20%) ⁹
= 3,892,314 CDs
Answer:
oh my my fr your not kidding
First work out the part in the parentheses
1 1/6 * 3
= 7/6 * 3 = 21/6 = 7/2
convert 4 1/5 to an improper fraction; that is 21/5
so we have 21/5 / 7/2 = 21/ 5 * 2/7 = 21 * 2 3*2
------- = ----
5 * 7 5
= 6/5 or 1 1/5
Answer:
x = 7.
Step-by-step explanation:
-18 = 6 (x - 10)
-18 = 6x - 60
6x = -18 + 60
6x = 42
x = 42/6 = 7.
1) you do 144× 12 since you want to know how much all kids pay so its 1728 dollars.
2) they want 2 section a, 3 section b, and 2 section c, and sincc you want to know total you multiply number of tickets bought by cost per ticket, so its 2(10)+3(20)+2(30)=180 total cost.
3) sine they have 350 dollars yoy subtract cost of the ps4 from the amount they have and you get, 350-234=116 dollars remaining.
4) since they make 15 per lawn you write 15x, x representing number of lawns cut, and you set that equal to 225, so its 15x=225 then you divide 15 on both sides to get x= 15 lawns they need to cut.
5) you just divide 2/4 since they ate two of four slices and you get .5 then convert that to a decimal by moving decimal point 2 spaces over to get 50%.
6) Just add up all the costs of each song, so you get .99+1.19+1.5+.99 = 4.67 dollars as total cost.
7) since 60 min is in an hour and you have 30 min left over it would be 1hr and 30 min.
8) since its Monday through Friday which is only 5 days you multiply that by 4 weeks to get 20 days then you multiply by 30 since they study 30 min on each of those days, so you get 20×30 which is 600min of studying, but since it want is in hours divide 600 by 60 to get 10hrs of study.
