Answer: Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3 =45 hours.

Duration of Tina practiced piano this month=  45 hours

If you have a box with a volume of 567 and 12 is the leangth, and 8 is the width, what is the height of the box?
Kryger [21]

Answer:

So Height of the box is 5.906

Step-by-step explanation:

Given:

Volume of box = 567

Length = 12

Width = 8

To Find:

Height = ?

Solution:

We know that a box is in the shape of a cuboid so

We know that

Volume of the cuboid is given by the formula which is

Volume = Length * Width * Height

Now we are given all the values in the question

putting in those values

Volume = Length * Width * height

Putting the values

567 = 12 * 8 * Height

567 = 96 * Height

Dividing both sides by 96 we get

Height = 567 / 96

So We get

Height = 5.906

So Height of the box is 5.906

What is the arc length of arc CD in the circle below? Circle A is shown with a radius labeled 15 feet and a central angle marked
Lesechka [4]
Arc length = angle (in rad!!) * radius:

45 degree = pi / 4 rad

Arc length = pi/ 4 * 15 = 15/4*pi feet or approx. 11.781 feet

Also in this case only, 45 degrees is 1/8 of the whole circle, so Arc length = 2pir/8 = pi/4*r, but only this case. the first formula always works!

I need help with this how do I do it
Anna35 [415]
Triangle angles add to 180 degrees. Thus, x - 17, x - 22, and 3x + 19 add to 180.

Add like terms to get 5x - 20 = 180
5x = 200
x = 40
