Answer:

a. 5 sets of tires

b. 16 times

Step-by-step explanation:

total distance commuted by the truck = 160,000 miles

a.tires of the truck are changed after every 40,000 miles

40,000 to 80,000 to 120,000 to 160,000 he will change his tires four times assuming he started his journey with the new tires. so, he needs uses a total of 5 sets of tires for the whole journey.

b. changes oil every 10,000 miles then to travel 160,000 miles

= \frac{160,000}{10,000}

= 16 times in whole journey

Answer:

I only got the answer for B, but its 16.

Step-by-step explanation:

You take 160,000 and divide it by 10,000. Why? If he goes 160,000 miles across america, and has to change it every 10,000 miles he gets 16. You're welcome!!!

Consider the scatter plot.
Leno4ka [110]

<u>Answer:</u>

The correct answer option is: The y-intercept of the line of best fit shows that when time started, the distance was 5 feet.

<u>Step-by-step explanation:</u>

We are given a scatter plot with a best fit line as shown on the given graph.

The equation of the best fit line is given by:

y = 0.75x + 5

So with the help of the equation and by looking at the given graph, we can conclude about the representation of the y intercept that the the y-intercept of the line of best fit shows that when time started, the distance was 5 feet.

Since the distance shown on the y axis is already 5 when the time started at 0 minutes.

REY [17]

Answer:

In order to tell if these are congruent triangles we would need to know if angles Y and V were congruent, angles X and W are congruent or if segments XU and WU were congruent.

Step-by-step explanation:

Any of these would work because you can use two different methods to telling that these are congruent triangles.

The first method is called side-angle-side. In it you need two side lengths that are congruent with a congruent angle in the middle. Since we already know that the right angle in the middle is congruent, and we know YU and VU are congruent, we would just need to know the additional side to prove congruence.

The second method is called angle, angle side. In this we need to know that two angles in a row are congruent followed by a side. Since we know the middle angle is the same, knowing either other angles would give us this method as well.
