30. you can model this with an equation and solve, x being the smallest number and the x+1 and x+2 representing the consecutive numbers.
x+(x+1)+(x+2)=93
3x+3=93
3x=90
x=30
x+1=31
x+2=32
30+31+32=93
Pi was discovered way back already the way to Babylonians and Egyptians 216 BC but none were all the way accurate they were close
Answer:
7
Step-by-step explanation:
No. of pizza Ronnie stacked = 0.25 × 40
= 10
No. of pizza Mack stacked = 9
No. of pizza Kim stacked = 
× 40
= 14
No. of pizza Ada stacked = 40 - 10 - 9 - 14
= 7
Well, since it is multiple choice, you can just eliminate the answers. If you take 5/4 it equals 1.25. Then you go through the choices. All of the numbers, except 7.2 (C) are infinite. And, 7.2 gives you the 1.25 from before... which is your answer
If this helped, brainliest would be great! Only need one more to level up :)
Answer:
400 lb of salt
Step-by-step explanation:
Let us assume the water flows into the rank for x minutes.
There is an initial of 1000 gallons of water in the tank and water flows in through one pipe at 4 gal/min and through another pipe at 6 gal/min. In x minute, the amount of water in the tank = 1000 + 4x + 6x = 1000 + 10x
Water flows out at 5 gal/min, therefore in x minute the amount of water in the tank = 1000 + 10x - 5x = 1000 + 5x
The tank begins to overflow when it is full (has reached 1500 gallons). Therefore:
1500 = 1000 + 5x
5x = 1500 - 1000
5x = 500
x = 100 minutes.
1/2 lb salt per gallon flows into the tank at 4 gal/min and 1/3 lb of salt is flowing in at 6 gal/min, in 100 min the amount of salt that entered the tank = 4 gal/min × 100 min × 1/2 lb/gal + 6 gal/min × 100 min × 1/3 lb/gal= 400 lb
Therefore the amount of salt is in the tank when it is about to overflow = 400 lb of salt
