kogti [31]

Answer:

Day 21: 810 m

Day 60: 1,200 m

Step-by-step explanation:

The amount of meters she walk everyday can be modeled as a linear function, as the rate of variation is a constant (10 m/day):

$dD/dt=10\;\text{m/day}$

This constant (10 m/day) is the slope of the linear function.

We know one point of the linear function (D(20)=800) and the slope, so we can calculate the y-intercept:

$D(t)=10t+b\\\\D(20)=10*20+b=800\\\\b=800-10*20=800-200\\\\b=600$

Now, we can calculate the distance she walks by day 21 and day 60:

$D(21)=10*21+600=210+600=810\\\\\\D(60)=10*60+600=600+600=1,200$

One hundred people in a supermarket survey

tiny-mole [99]

Answer:

13%

Step-by-step explanation:

So basically the people who had a pet in the store were: 47, 33, and 7 out of 100. Now we add up the numbers of the people who have pets which in total, is 87, out of 100. But that's not all. Those are the people who have pets to find the people who didn't have pets, we subtract 87 from 100 to get 13, or 13% as our answer.

-Hope this helped! :)
