PLEASE ANSWER QUICK WILL GIVE 5 STARS The number $y$ of calories burned after $x$ minutes of kayaking is represented by the linear function $y=4.5x$ . The graph shows the number of calories burned by hiking.

You perform each activity for 45 minutes. How many total calories do you burn?

202.5 calories

Step-by-step explanation:

y = 4.5x  where y is the calories burned and x is the minutes

Let x = 45 minutes

y = 4.5 * 45

y =202.5 calories

The average person burns 375 – 475 calories per hour kayaking.

The number of calories burned kayaking depends on your weight, the distance and speed you kayak, and difficulty of terrain. A 200-pound (90.8kg) person will burn 477 calories per hour kayaking with moderate effort. A 150-pound person will burn 358 calories per hour with the same activity.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
