Step-by-step explanation:
x+y=60
400x+250y=18600
x=60-y
400(60-y)+250y=18600
y=36.
solve this expression then u will get the answer for y.
x+36=60
x=24.
4x8=32 12x12=144 32 goes into 144 4.5 times
Answer:
13 quarters must be tails.
Step-by-step explanation:
Number of quarters = 40% of 50 coins
Number of quarters = 40/100 * 50 = 20 coins which are quarters.
35% of these 20 quarters on heads. We can proceed in 2 ways from here.
We can actually find the number of quarters that are on heads.
35/100 * 20 = 7 quarters are showing heads.
Since the other quarters must be tails 20 - 7 = 13 quarters must be tails.
The other way to do it is to realize that if 35% of the coins are heads, 65% of the coins must be tails 20 * 65/100 = 13 which is a bit more direct.
