Answer:
<u><em>15 cookies are chocolate</em></u>
Step-by-step explanation:
Well it's actually quite easy, just think about it this way. 20/4=5 since there's a 4 as the denominator in the fraction. Or there's many other ways to find the answer. At the end of the day, you'll get the same answer just some ways are harder especially compared to the one I did.
Since we divided 4 into 20, we know the answer to that is 5.
3/4=15 if you think about it in a certain way.
Therefore the answer is 15 since 3x5= 3/4 and both of those equal 15

Answer:
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
Step-by-step explanation:
Take a number, x.
Now increase it by 5%.
1.05x
Now increase it by 20%.
1.2 * 1.05x = 1.26x
1.26x = 126% of x = 100% of x + 26% of x
100% of x is the same as x, so it is the same as the original x.
The increase is 26% of the original number.
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
Lets see whether the river is going against the boat or with it
speed=distance/time
22 miles per 1.5 hour
speed=22/1.5=14.66666 mile per hour
50mph>14.6666666mph
ok it slowed down, so it it going agains the current
boatspeed-currentspeed=realspeed
realspeed=14.666666mph
boatspeed=50mph
50-curretn speed=14.66666666666666
50 both sides
-currentspeed=-35.33333333333333
multiply -1
currentspeed=35.33333333333333mph
the current is 35 and 1/3mph agains the boat
