8 0

Answer:

0.400

Step-by-step explanation:

COLORADO is 8 letters and you have 3 out of 8 of pulling a o 1 time out the bag so take 3 divided by 8 that gives you 0.375 and since you are rounding it you would rounded it to 0.400

HELP PLEASE!!! SHOW WORK!! A professional pianist spends an average of 45 hours practicing the piano in a three-week period. Usi
kicyunya [14]

Answer:

An average of about 450 hours; You could say something along the lines of "If the pianist who practices an average of 45 hours per week practices everyday for three months, they would play for approximately 450 hours total."

Step-by-step explanation:

We could write an equation to make it simpler to figure out, making the number of hours after three months = n, 4 = weeks in a month, 3 = the number of months, and 45 = the number of hours after a week. As an equation, it would look like:

45 * 3 * 4 = n

We know 3 *4 is 12, so the equation becomes 45 * 12 = n.

45 * 12 = 540, therefore the pianist practices an average of approximately 540 hours over a three-month period of time.

John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park. How much farther does John jog?
Elden [556K]

Answer:

1.9 miles.

Step-by-step explanation:

John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park.

Convert the fractions into decimals:

2 7/10 = 2.7

4/5 = 0.8

Subtract '0.8' from '2.7':

2.7-0.8=1.9

John should jog 1.9 miles farther than Marsha.

Hope this helps.

Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydive
Firdavs [7]

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>

Let distance = s    

      time = t

Therefore , s = k \times t^{2}

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k \times (2)^{2}

64 = k \times (4)

 k  = \frac{64}{4}

 k = 16 ft/s^{2}

We have to find how much he will fall in 10 seconds.

s = k \times t^{2}

s = 16 \times 10^{2}

s = 16 \times 100

s = 1600 ft
