Answer:

formula is speed equals distance/ time.

now, speed above is 85km/h and distance is 42km.

time therefore is 42/85 which is 0.494h

now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)

now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)

nikitadnepr [17]
Let A be asset turnover, R revenue, and S assets. You already know the equation for asset turnover:
A = R/S

Since we need to calculate revenue, we need to modify the equation a bit:
R = A*S
R = 7.2*88000
R = 633,600

This means that Ryan's net sales (revenue) were $633,600.

A used car lot sold 15 SUVs last month, along with 80 other vehicles. Considering this
sergiy2304 [10]

Answer:

12

Step-by-step explanation:

First, find the total number of vehicles sold.

15 SUVs were sold, and 80 others were sold

15+80

95

So, 95 vehicles were sold in total.

Now we can make a proportion

15 out of 95 vehicles were SUVs, and we can expect x out of 76 vehicles to be SUVs

15/95=x/76

Cross multiply

95*x=15*76

95x=1140

To solve for x, we need to get x by itself. Since x is being multiplied by 95, divide both sides by 95. This will cancel out the 95, and leave x isolated.

95x/95=1140/95

x=12

So, 12 out 76 vehicles should be SUVs
