Answer:

Andy went as furthest as possible with a gallon of gasoline

Step-by-step explanation:

Let

m ----> the distance in miles

g ----> the number of gallons of gas

step 1

<u><em>Kelley's Mileage</em></u>

Find the slope of the linear function of Kelley's Mileage

we have the points

(0,0) and (20,50)

slope=(50-0)/(20-0)\\slope=2.5\ miles/gallon

the linear equation is

m=2.5g

step 2

<u><em>Andy's Mileage</em></u>

Find the slope of the linear function of Andy's Mileage

we have the points

(15,78.75) and (30,157.5)

slope=(157.5-78.75)/(30-15)\\slope=5.25\ miles/gallon

the linear equation is

m=5.25g

step 3

Rick's Mileage

we have

m=4.8g

therefore

the slope is 4.8\ miles/gallon

step 4

Compare the slopes

5.25\ miles/gallon > 4.8\ miles/gallon > 2.5\ miles/gallon

therefore

Andy went as furthest as possible with a gallon of gasoline

4. Stella says the equation x^2−8x+y^2+2y=5 has a center of (4,−1) and a radius of 5. Is she correct? Why or why not?
Ostrovityanka [42]
<h2>Stella is correct about center and wrong about radius      </h2>

Step-by-step explanation:

Equation of circle with (h,k) as center and radius r is given by,

          (x-h)²+(y-k)² = r²

Here equation is

          x²−8x+y²+2y=5

Changing in to (x-h)²+(y-k)² = r² form

           x²−8x + 16 - 16 +y²+2y+1 - 1=5  

           (x-4)² - 16 + (y+1)² -1 = 5

           (x-4)²  + (y+1)²  = 22

           (x-4)²  + (y+1)²  = 4.69²

           Center is (4,-1) and radius is 4.69

Stella is correct about center and wrong about radius

Amira has 3/4 of a bag of cat food. Her cat eats 1/10 of a bag per week. How many weeks will the food last.
sergiy2304 [10]

Answer:15

Step-by-step explanation:

You have to divide the fractions so it 3/4÷1/10 then you can do keep change flip so the new equation is 3/4×10/1 or 3/4×10 then cross simply then get 3/2×5/1 to get 15/2 then use division to get 7 1/2
