It would just be -35.0, there is nothing else to change it's value beyond -35
Answer:
The cost of 30 gallons of gas is $74.7.
Step-by-step explanation:
- Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.
- The cost 24 gallons is $59.76 to him.
- Now we need to find the cost of 30 gallons.
- To solve this problem use a direct variation formula.
- Solve for constant variation.
Step 1 of 3
Here we need to find the cost of 30 gallons.
Given that the price that Tyler pays for gas varies directly with the number of gallons he buys.
The cost of 24 gallons is $59.76 to him.
Let, x be the number of gallons and y be the cost or price for gas.
Use the formula for direct variation which is given by y=kx.
Step 2 of 3
Now substitute the value y=$59.76 and x=24.
Put value in y=kx, we get

Substitute value of k is y=kx, we get y=2.49x
Step 3 of 3
Now we need to find the value of y that is the cost for 30 gallons.
Again use direct variation formula y=kx and value of k and x, we get 

Answer:
0 is rational
5 rational so u are correct
Step-by-step explanation:

Actually Welcome to the Concept of the volumes.
Here given as, r= 6.2 mm, h = 10.8 mm, π=3.14
hence, the volume of the cone is
Volume = 1/3(πr^2h)
===> vol = 1/3(3.14*(6.2)^2*(10.8))
==> Vol = 1/3*(1303.57)
==> Vol = 434.52 mm^3
Hence the volume of the cone is 434.52 mm^3
Answer=157 seconds
1256 seconds 8 laps
1256/8=157seconds per lap
