Andrea has a goal of running at least 50 miles this month. She has already run 7 miles. How many miles does Andrea need to run e

Nuetrik [128]

Answer:

At least 1.72 miles per day.

Step-by-step explanation:

Given: Goal of running is at least 50 miles in a month.

Andrea have already run 7 miles.

Days left in the month is 25.

As given, Andrea have already run 7 miles.

∴ Andrea need to run this month= $50\ miles - 7\ miles= 43\ miles$

Days remaining this month is 25.

Now, finding miles need to run each day to meet her goal.

Miles need to run each day= $\frac{remaining\ miles}{remaining\ days}$

⇒ Miles need to run each day= $\frac{43}{25} = 1.72\ miles$

∴ Andrea need to run at least 1.72 miles to meet her goal this month.

What is the area of a cirlcle that's 4cm

Elena-2011 [213]

If the radius of the circle is 4 than the area would be 50.27.

If you are saying that 4 is the diameter, than divide that by 2 to get the radius which is 2. The area for this would be 12.57.

I don’t know which one you mean but hope this helps :))

A function has a constant tripling time. What type of function does this represent?

Olenka [21]

This would be an exponential function.

Exponential functions are of the form

y = a*bˣ, where a is the initial value, b is the rate the function changes by, and x is the time period. Since this triples, b would be 3.
