Answer:

57.75

Step-by-step explanation:

Doug did clean 1 3/4 hour.

Doug did paperwork for 2 1/3 hour

Doug did serving for 1 5/12

Add 1 3/4+ 2 1/3+1 5/12=16/12 or 5.5 hrs

In one hour Doug earns $ 10.50 .

Therefore in 5.5 hour Doug earns 5.5 $ 10.50 = $ 57.75

Hence the total which Doug earned is $ 57.75

Three investors own a company. One partner owns 1/4 of the company , while the second partner owns 2/5 of the company . How much

Yakvenalex [24]

We want to add these together and then subtract from one. So to add them, find a common denominator.
The closest common denominator is 20.
So convert the fractions:
5/20 and 8/20
Then add
5/20 + 8/20 = 13/20
And then subtract from 1.
1 - 13/20 = 7/20
The third partner owns 7/20 of the company.

A cylinder has 18 inch diameter and is 15 inches tall it is filled to the top with water a 6 inch diameter ball is in place with

k0ka [10]

Answer: $1,179\pi\ in^3$

Step-by-step explanation:

The volume of a cylinder can be calculated with the following formula:

$V=\pi r^2h$

Where "r" is the radius and "h" is the height.

The volume of a sphere can be found with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

Then, volume of the empty cylinder is:

$V_c=\pi (\frac{18\ in}{2})^2(15\ in)\\\\V_c=1,215\pi \ in^3$

And the volume of the ball is:

$V_b=\frac{4}{3}\pi (\frac{6\ in}{2})^3\\\\V_b=36\pi \ in^3$

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

$1,215\pi \ in^3-36\pi \ in^3=1,179\pi\ in^3$

A hot air ballon ascended at the rate of 400 dreams per hot for 3 hours and 15 min. What was the total distance that the ballon

alexandr1967 [171]

If it is 400 m/s then it's the answer

v= s/t
400m/s= s/11700 195×60=11,700 sec
s= 400 × 11700
s= 4,680,000 m/s ^2

11,700×400=4,680,000
