Four runners start at the same point; Lin, Elena, Diego, Andre. For each runner write a multiplication equation that describes t
Natalka [10]

Answer:

See the answers in the explanation

Step-by-step explanation:

Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?

time= 29 seconds

speed= 7.2 m/s

distance= speed*time

distance= 7.2*29

distance=208.8 m

Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?

time= 26 seconds

distance= 240meters

velocity= distance/time

velocity= 240/26

velocity=9.23 m/s

Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?

time= 33 seconds

velocity

distance=velocity*time

distance=33*6.1

distance= 33*6.1

distance=201.3 m

Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?

time= 38 seconds

distance= 295m

velocity= distance/tim

velocity= 295/38

velocity= 7.76m/s

Mrs. Miller sells a house for 179,000. If she earns a commission of 6%, how much money does she earn? ( can u also show me how u
Kryger [21]

Hi there!

Mrs. Miller earns a commission of 6% of 179,000

The word "of" is the same thing as a multiplication sign.

6% of 179,000 = 6% × 179,000

6% = 0.06

6% × 179,000 = 0.06 × 179,000

0.06 × 179,000 = 10,740


Your answer is: Mrs. Miller earns $10,740 of commission.


There you go! I really hope this helped, if there's anything just let me know! :)

One faucet fills up a bathtub in 15 minutes while the second fills it up in 10 minutes. If both faucets are turned on, what frac
yaroslaw [1]
Faucet one fills up \frac{1}{15} of the bathtub in one minute and faucet two fills up \frac{1}{10} of the bathtub in one minute. If both are one then they will fill up  \frac{1}{15}+ \frac{1}{10} =  \frac{5}{30} =  \frac{1}{6} So, 1/6 of the bathtub in one minute.
