Answer:

Collen's average speed was 11.875 miles/h

Step-by-step explanation:

The average speed is given by the total distance travelled divided by the time at which the route was completed. So in this case the total distance is 9.5 miles and the time to complete it was 0.8 hour. We then have:

average speed = total distance/ time

average speed = 9.5/0.8 = 11.875 miles/h

Collen's average speed was 11.875 miles/h

Answer:

Option a: 11.875 miles per hour

Step-by-step explanation:

We can calculate Colleen's average speed using a rule of three:

She rode a total of 9.5 miles in 0.8 hours, so how much she would rode in 1 hour (this way we can calculate her speed in miles per hour)

9.5 miles -> 0.8 hours

X miles -> 1 hour

9.5/X = 0.8

X = 9.5 / 0.8 = 11.875 miles per hour

The correct option is option "a".

Log (4x-1)+5=8<br><br> Please help me!
nordsb [41]

log (4x-1) + 5 = 8

log (4x-1) = 8 - 5

log (4x-1) = 3

4x - 1 = 10³

4x - 1 = 1000

4x = 1001

x = 1001/4

Correctly order the following numbers from LEAST to GREATEST:
ivanzaharov [21]

- 7 1/5 <  - 2.3 < 0 < π  < 23/7 is ascending order of these numbers.

What do descending order and ascending order mean?

  • Climbing down the stairs of numbers starting with their highest value is another way to think of descending.
  • The slide is descended while moving down it.
  • Ascending order, in which the numbers are organized from lower value to higher value, is the reverse of falling order.

The values are 0 , -2.3 , π , 23/7 , -71/5

first simplify all the values  0 , - 2.3 , 3.14 , 3.28 , -7.2

now arrange all value in Ascending order

 - 7.2 < -2.3 < 0 < 3.14 < 3.28

- 7 1/5 <  - 2.3 < 0 < π  < 23/7
