The equation to best represent the situation will be:
7 + f = 15
You take the number you know (7) and the fruit that you add will equal 15.

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.
Volume of whole ahape = volume of Cylinder + volume of sphere ~
<u>Volume</u> <u>of</u> <u>sphere</u> :




<u>Volume</u> <u>of</u> <u>Cylinder</u> :




<u>Volume</u> <u>of</u> <u>whole</u> <u>shape</u> :


Answer:
51
Step-by-step explanation:
450 < 10x - 1x
450 < 9x
50 < x
you must sell 50 tickets to break even; 51 to make a profit
4m + 14 - 2m < 2 (m+7)
4m+14-2m<2m+4
4m-2m-2m<4-14
0<10
