Hi! :)
The radius of a circle is the length from the perimeter of the circle to the center of the circle.
If 24 inches is still 9 inches from the center, you just have to add 24 and 9 to get the radius.
24+9= 33
Your final answer should be that the radius is 33 inches.
Hope this helps!
Subtract the volume of the water from the volume of the tank to get the total volume of the marbles.
26 liters - 20.9 liters = 5.1 liters
He has 20.9 liters of water.
He has 85 marbles that add up to 5.1 liters of volume.
To find the volume of one marble, we divide 5.1 liters by 85.
(5.1 liters)/85 = 0.06 liters
The volume of each marble is 0.06 liters.
If he uses 200 marbles, the the marbles will occupy 200 * 0.06 liters = 12 liters.
The volume of the tank is 26 liters. 12 liters of volume is occupied by the marbles. The rest of the volume is water.
26 liters - 12 liters = 14 liters
Answer:
7 packs
Step-by-step explanation:
2.75p < 20
Divide both sides by 2.75
2.75p/2.75 < 20/2.76
Simplify
p = 7.27 (27 repeating)
Round
p = 7
Answer: Y= -5 and X= 1
Step-by-step explanation:
Linear equations, huh? Okay, well we'll subtract for this problem. 7x minus 7x is nothing, so x is all cancelled out. Negative y minus 3y is -4y. And 12 minus -8 is 20, since the two negatives become a positive. So we have -4y = 20, so y equals -5. Great, so now we plug in y in one of the equations. I'll chose the top one. Our new equation is: 7x+5=12. Subtract both sides by 5, and we have 7x=7. Well, this means that x equals 1, therefore giving y equals -5, and x equals 1.
Aight, let's check. Plug in both variables for both equations. We get 7+5=12, and 7-15= -8
