Answer:

21 years

Step-by-step explanation:

M: distance she drives (miles)

G: no. of gallons used

125/6000 = 1/48

G = M/48

Or

M = 48G

M = 12000

12000 = 48G

G = 250 gallons

Each gallon: $2.4

Cost = 2.4 × 250 = $600

Evan's cost:

(12000/30) × 2.4 = $960 per year

Anna's fuel cost per year: $600

23740 + 960t = 31140 + 600t

360t = 7400

t = 20.556

A. I suppose the horizontal axis represents the amount of miles Anna drives. You're asked to use the graph to find an equation for the line. You know two points it passes through; this is enough to determine the slope of the line:

\dfrac{250-125}{12,000-6,000}=\dfrac{125}{6,000}=\dfrac1{48}

Now use the point-slope formula to get the line's equation. Using the leftmost point, for instance, we have

y-125=\dfrac1{48}(x-6,000)\implies y=\dfrac x{48}

This is to say, the amount of fuel y (in gal) that Anna uses is given exactly by dividing the distance traveled x (in mi) by 48.

B. Driving 12,000 mi requires 250 gal of fuel (according to both the rightmost point on the graph as well as the value of y in the previous equation for x=12,000). She pays $2.40 per gal, so the total cost for 250 gal is

($2.40/gal) * (250 gal) = $600

C. Evan's car uses approximately

(12,000 mi) / (30 mi/gal) = 400 gal

per year, which costs him an annual total of about

(400 gal) * ($2.40/gal) = $960

We need to know the price of Anna's car to answer the actual question, though...

What is m&lt;KNL? <br>Enter your answer in the box<br>​
steposvetlana [31]

The measurement of ∠KNL   is 102°

First, you must set up an equation to find x.

5x+2=[3(x+14)

Then, you must simplify both sides of the equation.

5x+2=3x+42

Next, subtract 3x on both sides.

2x+2=42

Then, subtract 2 on each side.

2x=40

Next, divide 2 on each side.

x=20

Now that we have the value of x, we can substitute it in for angle KNL.

[3(20+14)]

[3(34)]

102

The curved urface area of a cone i 140π cm2. What will be the radiu of a cone whoe lant height i 5 cm
VashaNatasha [74]

The radius of a cone with a curved surface area of 140π cm² and a slant height of 5 cm will be 28 cm.

<h3>What is curved surface area?</h3>

The region with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Total Surface Area is the combined area of the bases and the curved surface. The measurement of a solid's curved surface area is its outer area, which excludes the top and bottom extensions. Surface area of the cylinder that is curved: A right circular cylinder is the solid that results when a rectangle circles around one side and makes a full revolution. The curved surface area of a cylinder (CSA) is also known as the lateral surface area and is defined as the area of the curved surface of any given cylinder having a base radius "r" and height "h".

Here,

Curved surface area of cone=πrl

=140π

l=5 cm

140π=πr*5

r=140/5

r=28 cm

The radius of cone that has 5 cm as slant height and 140π cm² as the curved surface area will be 28 cm.
