1/5 of 20 is $4. so 20-4=$16 remaining
3/8 of 16 is $7.50. So, 16-7.50= $8.50 remaining
2/7 of 8.5 is $2.43. So, 8.50-2.43 is $6.07
Answer: $6.07 is the amount ken has remaining
The rate of travel, or speed, is
200 miles
--------------- = 40 mph
5 hours
Recall that distance = rate times time, so that rate = distance / time.
Okay so
If there are 28 white ducks, and twice as many brown ducks thats
28x2=56
So the total amount of ducks is 56(brown)+28(white)=84
Then, if half the amount of while ducks fly away thats
84-14=70 (You get 14 by diving the amount of white ducks by 2 28/2=14)
Therefore, there are 70 ducks in the pond after half the amount of white duckies fly away.
Answer:
D.) 38.6 m
Step-by-step explanation:
Use the cosine ratio:
Because we are given the measure of an angle and the length next to it (adjacent), and we need to find the hypotenuse (the hypotenuse is NEVER considered the adjacent side). Insert the values:
Now isolate the variable. Multiply both sides by x:
The x's on the right side cancel each other out. Simplify:
Now divide both sides by cos75°:
The cos75° on the left side cancels each other. Simplify:
Insert this value into a calculator to simplify the value of x:
The hypotenuse is 38.6 m.
