Answer:

y = -0.2x + 8

Step-by-step explanation:

To write a linear function, calculate the rate of change of the gallon of water leaving the tank and the starting level.

The function will describe the number of gallons over time or (time, gallons).

This means the function has data points (1, 7.8) and (9, 6.2).

Use the rate of change or slope formula to calculate it.

m = \frac{7.8 - 6.2}{1 - 9} =\frac{1.6}{-8} = -0.2

This means that for the formula y = mx+b then m = -0.2.

This also means that after losing 0.2 gallons the first hour it was at 7.8. So the starting value is 8 gallons.

The equation is y = -0.2 x + 8.

miss Akunina [59]

Answer:

Using formula to calculate the circumference of wheel:

 

where

D is the distance bike travel

n is the number of times rotation

C is the circumference of the wheel

As per the statement:

Lin’s bike travels 100 meters when her wheels rotate 55 times.

here, n = 55 rotation and D = 100 meter.

then by definition:

meter

Therefore, the circumference of her wheel is, 1 9/11

How to solve which fraction is larger 10/13 or 11/14 or 14/15 or 17/18
alexandr402 [8]
To solve these type of problem you have to make the denominator the same or use the claculator.

let us do this problem by making the denominator the same.

\frac{10}{13} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{11}{14} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{14}{15}  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{17}{18} \\\\ \frac{10}{13}\times \frac{3780}{3780} \ \ \ \ \ \ \ \ \ \frac{11}{14} \times \frac{3510}{3510} \ \ \ \ \ \ \ \ \ \frac{14}{15} \times \frac{3276}{3276} \ \ \ \ \ \ \ \ \ \frac{17}{18} \times \frac{2730}{2730}

\frac{37800}{49140} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{38610}{49140}  \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{45864}{49140}  \ \ \ \ \ \ \ \ \ \ \ \ \ \ \    \frac{46410}{49140}

So, now. the one with the largest numerator is the largest fraction

In this case, \frac{46410}{49140} is the largest which is equal to \frac{17}{18}.

So, the largest fraction is \frac{17}{18}.
