Answer:
4.5 hours
Step-by-step explanation:
distance equals rate times time, a relationship that can be solved for time:
time = distance / rate
Here the time is (135 miles) / (30 mph) = 4.5 hours
The bus requires 4.5 hours to get to the museum.
Answer:
0.1
Step-by-step explanation:
In a problem like this the number that is more to the left is greater. As you can see 0.1 is more to the left
The function that models exponential growth is:
P(t) = P0*(1 + r)^t, where
P0 = P(0) is the initial value of P
r is the growth rate as a decimal
In our case we have:
P(0) = 2800
r = 0.035 or 3.5%
P(t) = 2800*(1 + 0.035)^t
P(t) = 2800*(1.035)^t
The same exponential function written using y and t is:
y = 2800*1.035^t.

Answer:
180 plants
Step-by-step explanation:
the area of a right triangle is: ab/2
side a = 8
side b = 15
8 x 15 = 120
120/2 = 60
Michael wants 3 plants for every square yard (multiply by 3)
60 x 3 = 180
