Answer:
It takes 1.68 hours to catch up to them.
Step-by-step explanation:
The speed of robber = 71 mph
The speed of police = 78 mph
The police start 10 minutes later
by that time robber would have travelled
10 minutes =0.166667 hours
then the distance = 11.8 mph
Let them meet at distance x from the bank.
time taken by police to reach x , time =
----------------------(1)
time taken by robber in the same time = 
---------------(2)
Equating (1) and (2)
71x =78x - 920.4
920.4 = 78x - 71x
920.4 = 7x
x = 131.48
The distance where they catch up with the robber from the bank is 131.48 miles
speed of police = 78 mph
distance = 131.48 miles
time they catch up = 
= 1.68 hours
It would be 30.7% because when you change a decimal to a percent, the decimal point moves 2 places to the right. For a percent to a decimal, move the decimal point 2 places to the left
Answer:
68 degrees
Step-by-step explanation:
Given: LMN and TUV are complementary angles
LMN = 22 degrees
This means that LMN and TUV add up to 90 degrees.
We can use this to set up an equation:
LMN + TUV = 90
Plug in 22 degrees for LMN
22 + TUV = 90
Subtract 22 from both sides to isolate TUV
TUV = 68 degrees
Answer:
if the x after the 20 means multiply then the answer is -34/7 or -4 6/7 if the x is a letter then it's 2/11
Step-by-step explanation:
20x2-7x=6
20x2=40
40-7x=6
subtract 40 from 6= 34
-7x=34
34÷-7= -34/7 if needed in a mixed fraction -4 6/7
