Answer:

170

Step-by-step explanation:

19 45 - 16 55

For convenience, let's find the lapse from 17 00 till 19 45, it's simple 2 hours and 45 mins.

Now add the 5 mins we neglected (from 16 55 to 17 00).

That's 2 hours and 50 mins

1 hour = 60 mins

2 hours = 120 mins

2 hour 50 mins = 170 minutes

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank

hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

$24 \times 12 \frac{1}{2} \times 12 \frac{3}{4}$

Change the numbers to improper fractions

$24 \times \frac{25}{2} \times \frac{51}{4}$

We cancel out to get

$3 \times 25 \times 51$

$3825$

If sector area of the shaded circle garden is 8π, and radius of the circle garden is 8 inch. Below figure represent the given sc

otez555 [7]

Answer:

The measurement of the central angle AOB is 45 degrees

Step-by-step explanation:

To solve this problem, we will have to work with fractions.

We will get the fraction of area the shaded portion is when compared to the whole garden.

First of all, we will need to calculate the area of the garden which is $\pi r^{2}$

in this case, our radius is 8 inches.

Next, we will compare the area of the sector to the area of the garden. This will be

This will be the shaded area/ area of the whole garden

= $\frac{8\pi}{\pi8^{2}}$

$=\frac{1}{8}$

We will now convert this ratio to an angle by multiplying it by 360 degrees.

This will be:

$\frac{1}{8}\times 360 = 45 degrees$

The measurement of the central angle AOB is 45 degrees
