Answer:
domain is (xo ≤ x ≤ 0.45 )
range is (xo ≤ y ≤ 8.1 )
Step-by-step explanation:
given data
constant speed = 18 miles per hour
total time = 27 minutes = 0.45 hour
solution
we consider here Domain number of hours = x and Range distance traveled = y
we apply here distanace formula that is
Distance = speed × time .........................1
put here value
Distance = 18 × 0.45 = 8.1 miles
and no of hours x = 0 to 0.45 hours
so here
So domain is (xo ≤ x ≤ 0.45 )
and
Distance is 0 to 8.1 miles
So range is (xo ≤ y ≤ 8.1 )
Answer:
66 km
Step-by-step explanation:
Given that
Number of km's traveled by a car using g liters of gasoline = 12g
Number of gallons of gas required to travel 12g kilometers = g
We have to find
How far this car can travel using 
or 5.5 liters of gasoline = x= ?
Now we can find this by substituting g= in the the above equation representing number of kilometers traveled by the car.
Number of km's traveled by a car using liters of gasoline = 12 ()
x = 12 (5.5)
x= 66 km
So, the car travels 66km in 5.5 liters of gasoline
Answer:
5 x
Step-by-step explanation:
Simplify the following:
7 x - 2 x
7 x - 2 x = 5 x:
Answer: 5 x
P(selecting a brown ball first) = 6/14 = 3/7
P(selecting a pink ball) = 8/14 = 4/7
Probability of selecting a brown then a pink = 3/7 * 4/7 = 12/49 (answer)
