How can you solve this step by step?<br> 812 divided by 12?
makkiz [27]

Answer:

How I answered this was

Line up 812 divided by 12

So 81 divided by 12 = 72

Subtract 81 - 72

Which would equal 9

then bring down the two in 812

Which would make it 92

Then divide that by 12

which would equal 84

the subtract 92 - 84

that would equal 8

put a decimal then bring down a 0

that would be 80 then divide 80 by 12

that would be 7 which would equal 8 again

so our answer would be 67.6 continuous.

A pyramid has a height of 8 inches and a volume of 120 cubic inches. Determine 2
Pie

Answer:

1.     9 * 5 in.

2.    3 * 15 in.

Step-by-step explanation:

Volume = 1/3 * area of the base * height

120 = 1/3 * A * 8

So A = 120 / (8/3)

= 120 * 3/8

= 45 in^2.

So the dimensions of the base could be 9 * 5 in

or 3 * 15 in.

Type the correct answer in the box. The motion of a clock pendulum is modeled by this graph. The function describing this graph
Andreyy89

Answer:

The range of the function is -10, 10.

 The period of the function is 1.2 seconds.

The maximum of the function is 10 centimeters.

Step-by-step explanation:

The range of a cosine function is the set of output values. In this situation, the range is the distance the pendulum covers, which is represented on the D(t) axis. The graph shows that the range of the function D(t) is [-10, 10].

The period is the length of a cycle. The graph shows that the cycle repeats every 1.2 seconds.

The maximum is the y-value of the highest point on the graph. The graph shows the maximum of the function is 10 centimeters.
