9514 1404 393

Answer:

  B 12.5%

Step-by-step explanation:

  % change = ((new value)/(old value) -1) × 100%

  = (36/32 -1) × 100% = 1/8 × 100% = 12.5%

Peter increased his crunches by 12.5%.

The runner has to race for 21km. She has to finish race before 1h 40min. What avarage speed She has to run to gain such goal?
abruzzese [7]

Answer:

The rate of the runner is 3.5 meters per second.

Step-by-step explanation:

To get this answer in meters per second, we first have to convert each of the terms into either meters or seconds. We can do that by multiplying by unit rates.

21 km * 1000 = 21,000 meters

1 hour * 3600 = 3,600 seconds

40 minutes * 60 = 2,400 seconds

Now we divide the meters by the total number of seconds to get the rate.

21,000 meters / (3,600 + 2,400) secs

21,000 meters / 6,000 secs

3.5 meters per second.

During the spring car wash, the activities club washed 14 fewer cars than during the summer car wash. They washed a total of 96
Mashutka [201]
You can make an equation to solve this, but establishing knowns, unknowns, and relationships.

# in spring wash = x
# in summer       = x + 14
Total Washes     = 96

we know:
total = summer + spring

96 = (x) + (x + 14)
96 = 2x + 14
82 = 2x

"x" = 41
