Answer 2

Answer:

#5- 7.8 hours #6- $5.25

Step-by-step explanation

Question #5- 7.8 hours

First we have to find the speed. If the speed was constant we should be able to divide the miles by the time to find the speed. So 239.82 divided by 4.2. This would leave us with a speed of 57.1 mph. So to finish the question, we have to take what we know and divided it by the speed. If he drives 445.38 miles at the same speed of 57.1 mph it would take him 7.8 hours. I got this answer by dividing the miles by the speed. 445.38 divided by 57.1. Which got us our time, 7.8 hours.

Question #6- $5.25

Okay so we know that the chips cost .75 cents a bag, and he got two bags. So if we take .75 and multiply it by two we get 1.50. So the chips alone cost $1.50. We can take the price of the chips and subtract it from the total price. 22.50-1.50. 21. Now we have just the prices of the sandwiches. If we take the total price of the sandwiches and divide it by the number of sandwiches bought, we get $5.25. So each sandwich cost $5.25 each.

Are these triangles similar? Why?

A. Yes, SSS~ Postulate

B. Yes, SAS~ Postulate

C. Yes, AA~ Postulate

D. No, they are not similar.

Answers

it looks like yes, SSS

Answer:

Step-by-step explanation:

<Q is common to both triangles.

130 / 40 = 3.25

Call DQ = x

40/130 = x / (x + 72) Cross multiply

40*(x + 72) = 130*x

40x + 2880 = 130x Subtract 40 x from both sides

2880 = 90 x Divide by 90

x = 32

(72 + 32)/32 = 104/32 = 3,25

The ratios are the same.

Therefore the triangles are similar by SAS

Step-by-step explanation:

You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2

Answer:

The rate of change is -2

Step-by-step explanation:

Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2

Therefore the rate of change is -2

Answers

Answer:

n = 2

Step-by-step explanation:

Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4

This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.

We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.

-n = -2,

Graphing plobem 8th grade. First anserw gets brainest Can someone edit this short essay... make it sound smart, please :) [1] Kicking a ball in a net and scoring, is not as important as saving lives. Soccer to me would be considered overrated. Many fans have problems when it comes to cheering for their team. It causes many conflicts, that cant be solved by a simple resolution like shaking hands. Sports, especially soccer is not worth a heart attack or increase of blood pressure. Those scoring in a soccer game earn more money than a doctors salary who saves lives of human beings every second of the time in the world. [2] Based on my experience, watching soccer games or being a fan of any type of sport shouldnt cause your blood pressure to decrease or increase. Conflicts rise between a team against another team, and instructors against other instructors. Many dont keep in mind that we dont live on earth eternally, so theres no need to waste time thinking about a lost game. [3] Overrated is often used to diminish concepts, places, and even roles. I believe that soccer does not deserve the prestige it is given today. I know mostly about famous soccer players who can score goals two times in a row, than I know about doctors who scored an important goal by saving the lives of people, who were on the border of loosing their lives.
