hich explanation correctly tells how to calculate the time it will take Tristan to complete his swim? A. Step 1: Figure out the total number of miles Tristan swam (8 × 0.25). Step 2: Divide that distance into his average speed (60 ÷ 2). B. Step 1: Figure out the total number of miles Tristan swam (8 ÷ 0.25). Step 2: Multiply that distance by his average speed (32 × 60). C. Step 1: Figure out the total number of miles Tristan swam (8 ÷ 0.25). Step 2: Divide that distance by his average speed (32 ÷ 60). D. Step 1: Figure out the total number of miles Tristan swam (8 × 0.25). Step 2: Multiply that distance by his average speed (2 × 60).

Total of 8 times
Distance is 0.25 miles

8 * 0.25 is 2 so a total distance of 2 miles

We know his avg swim rate to be 60 minutes per mile, meaning if he traveled 2 miles then we multiply it by 60 to get our total time taken.

60min/mile * 2 miles = 120 minutes total

So, step D is the same as what I've done to calculate the total time it will take Tristan to swim around the lake

when full the gas tank of a car holds 15 gallons. it now contains 12 gallons. what percent represents how full the tank is?
Masteriza [31]

Hello!

to find the percent of a whole, use this equation here:

(remaining) / (total) = X

X * 100 = %

in this case:

12 / 15 = 0.8

0.8 * 100 = 80

your answer is 80%

I hope this helps, and have a nice day!

How many solutions does the nonlinear system of equations graphed below have?
NeTakaya

Answer:

Three solutions.

Step-by-step explanation:

In order to solve system of equations by graphical method, we graph the system of equations. The intersection point (s) of the two graph would give us the solution.

If the graph of the equations intersect at 2 points then there will be 2 solutions, if there are 4 intersection then there would be 4 solutions and so on.

For the given graph, we  can see that there are three intersection points.

Hence, there would be three solutions.
