Answer: 685 red marbles

Step-by-step explanation:

Lets set up a proportion:

x/1096 = 5/8

(For every 8 marbles, 5 of them are red)

Then we cross multiply

5480 = 8x

and divide!

so 685 marbles

What is the volume of the metal in this heavy-duty pipe? (It is not drawn to scale and the inside of the pipe is empty space.) S
Jlenok [28]
The volume of the pipe is about 282.6 cubic feet.

First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).

pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7

The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6

The function f(t) = 20 sin (pi over 5t) + 12 models the temperature of a periodic chemical reaction where t represents time in h
gregori [183]
The answer for the exercise shown above is the second option, which is: <span>Maximum: 32°; minimum: −8°; period: 10 hours.
 The explanation is shown below:
</span> You can make a graph of the function given in the problem above: f(t)=20Sin(π/5t)+12.
 As you can see in the graph, the maximum point is at 32 over the y-axis, and the minimum is at -8.
 The lenght of the repeating pattern of the function (Its period) is 10.

sveta [45]

Answer:

x=80°

Step-by-step explanation:

Triangles always add up to 180°.

As you have 2 angles, you would have to add them together and then take it away from 180° to get your answer.

50+50=100°

180-100=80°

Hope this helps :)
