Answer:
2 and a half times?
Step-by-step explanation:
if they always vistit with trainer it would be 60 divided by 150 and that gives you 2.5 but that wouldnt make much sense.
Answer:
-1
Step-by-step explanation:
to find x, use the following formula:
y = mx + b
(y = 0)
(m = change in y-value ... which is 2)
(x = change in x-value ... which is 2)
(b = y-axis ... which is -2)
y = mx + b
y = 
+ -2
= 1
y = 1 + -2
y = -1
Answer:
y = 2
Step-by-step explanation:
from the question which says that y is directly proportional to the positive square root of x can be expressed mathematically by saying
y ∝ √x
y = k√x..................................................... where k is the constant of proportionality.
y = 12, x = 9 , k = ?
from
y = k√x
12 = k√9
12 =3k
divide both sides by the coefficient of k which is 3
12/3 = 3k/3
4 = k
therefore K = 3
now, to find the value of y when x = 1/4
from y = k√x
y = 4√1/4
y = 4 × 1/2
y = 2
therefore the value of y when x = 1/4 in this expression y = k√x is 2
So this problem is asking for the difference in the total amount of gas in the tank and the amount of gas consumed. You have the total amount of gas–15 gallons. You have the information in the problem to find the amount of gas consumed. The car can go 32 miles before consuming a full gallon of gas and it traveled 384 miles. So if you divide the 384 miles by 32 miles per gallon, you are left with the gallons consumed. Once you have this number, you can subtract it from 15 gallons–the total amount of gas in the tank–to get how much gas is left.
