Answer:
20 miles
Step-by-step explanation:
Set up a proportion...
0.8 miles is to x miles as 6 mins is to 2.5 hours
*You need to convert 2.5 hours into minutes first, since the first part is in minutes. There are 60 minutes in an hour, so there are 60(2.5) = 150 minutes in 2.5 hours
0.8/x = 6/150
Now solve for x by cross multiplying...
0.8(150) = 6x
120 = 6x
20 = x
She can ride 20 miles in 2.5 hours
Answer:
D and E
Step-by-step explanation:
27 and 50 are greater than 20. The scale factor is more than 1, so the answer(s) have to be more than 1.
Answer:
the intercept of the line with the y-axis. Substitute the line's slope and intercept as "m" and "c" in the equation "y = mx + c." With this example, this produces the equation "y = 0.667x + 10.33." This equation predicts the y-value of any point on the plot from its x-value.

Answer:
Step-by-step explanation:
radius of semicircle = 5
area of semicircle = πr² = 25π
area of rectangle = 10×14 = 140
total area = 140 + 25π ≅ 218.54 square units
I’m not great at math so I could easily be wrong, but
I divided the 18.24 millimeters by 12 pennies and got 1.52
So if the pennies are all the same size, each penny should 1.52 millimeters.
To show work:
18.24/12=1.52
