Fabric is sold by the yard. You are buying fabric to make a blanket and the first yard is $10 and each additional yard is $8. Write an expression to model this situation

Answers

the expression is 8x + 10

Answer:

8x + 10

Step-by-step explanation:

Its 8x + 10 because its saying that the first yard is $10, and each additional yard is $8. To represent that, its already giving us the cost for the first yard, which is $10. And to represent each additional yard, we will use a variable combined with 8 which is 8x.

Using the divisibility rules, explain why 678 is divisible by 2, 3, and 6.

Answers

Answer:

678

678 is even, so it's divisible by 2

6+7+8 = 21, which is divisible by 3, so 678 is divisible by 3

Since 678 is divisible by both 2 and 3, it has to be divisible by 6

Sasha's mom is ordering food trays for Sasha's elementary school graduation party. Banquet Brothers sell a tray with 48 servings of pasta for $60. Cookin' Catering sells a tray with 30 servings of pasta for $72. Which company has the better deal?

Answers

Answer: Banquet Brothers has better deal.

Step-by-step explanation:

Given: Banquet Brothers sell a tray with 48 servings of pasta for $60.

Cost per serving = [tex]\$\dfrac{60}{48}=\$\dfrac{5}{4}=\$\ 1.25[/tex]

Cookin' Catering sells a tray with 30 servings of pasta for $72.

Cost per serving = [tex]\$\dfrac{72}{30}=\$\ 2.4[/tex]

Since, Cost per serving in Banquet Brothers < Cost per serving in Cookin' Catering

So, Banquet Brothers has better deal.

BD bisects m m Find m

Answers

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

[tex]m\angle ABC = 77.2^\circ[/tex]

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

[tex]m\angle ABD=m\angle CBD[/tex]

Substituting the algebraic expressions for both angles:

[tex]2.5x + 8.6=3.5x - 3.4[/tex]

Subtracting 8.6 and 3.5x:

[tex]2.5x - 3.5x = -8.6 - 3.4[/tex]

Operating:

[tex]-x = -12[/tex]

[tex]x = 12[/tex]

The two angles are:

[tex]m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ[/tex]

[tex]m\angle CBD=3.5x - 3.4 = 38.6^\circ[/tex]

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

[tex]m\angle ABC = 2*38.6^\circ=77.2^\circ[/tex]

[tex]\mathbf{m\angle ABC = 77.2^\circ}[/tex]

Kelko will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $57 and cost an additional $0.08 per mile driven. The second plan has an initial fee of $50 and costs and additional $0.10 per mile driven.

Answers

Questions (contd)

(a) For what amount of driving do the two plans cost the same?

(b) What is the cost when the two plans cost the same?

Answer:

(a) 100 miles

(b) $65

Step-by-step explanation:

Given

Plan 1:

[tex]Initial\ Fee = \$57[/tex]

[tex]Additional = \$0.08[/tex] per mile

Plan 2:

[tex]Initial\ Fee = \$50[/tex]

[tex]Additional = \$0.10[/tex] per mile

Solving (a): Number of miles when both plans are equal

Represent the distance with x and the cost with y

So:

Plan 1:

[tex]y = 57 + 0.08 * x[/tex]

Plan 2:

[tex]y = 50 + 0.10 * x[/tex]

To solve (a), we equate both plans together; i.e.

[tex]y = y[/tex]

[tex]57 + 0.08x = 50 + 0.10x[/tex]

Collect Like Terms

[tex]0.08x - 0.10x= 50 - 57[/tex]

[tex]-0.02x= -2[/tex]

Solve for x

[tex]x = -2/-0.02[/tex]

[tex]x = 100[/tex]

Hence, 100 mile would cost both plans the same

Solving (b): Cost when both plans are the same:

In this case, we simply substitute 100 for x in any of the y equation.

[tex]y = 57 + 0.08 * x[/tex]

[tex]y = 57 + 0.08 * 100[/tex]

[tex]y = 57 + 8[/tex]

[tex]y = 65[/tex]

Hence, the amount is $65

Read the story. Racing to Race Carlo stopped to rest for a minute and tried to catch his breath. Hed been running for so long that he had pains in his side and his legs were beginning to hurt. He hunched over and tried to expand his lungs, but it was like trying to suck air out of a bicycle tire. His body was too exhausted to even allow him to take a deep breath, and he started to wheeze again. Great, he thought, let me just add asthma to my expanding list of ailments. I cant believe that I cant even jog two miles without completely collapsing! He finally gave in to his aching body and laid down on the grass to recuperate. He closed his eyes and tried to imagine himself running on the school track in the 1,600-meter race. He pictured himself running steadily toward the finish line, running effortlessly like a cheetah in the jungle. He was so lost in thought that he didnt even hear Meiya approach. Hey sleepyhead, what are you doing napping on Seans lawn in the middle of the day? Meiya asked playfully. Carlo quickly sat up, breathing normally now and feeling a little embarrassed. I am trying to get in shape to try out for track, but I cant even run two miles, he said dejectedly. Wait, how many months are you out of surgery? Didnt you just finish rehab last week? Meiya asked. You cant expect to run two miles the first day. It had been six months since Carlos surgery and he specifically remembered the doctor telling him he could start running after six months. But he thought about what Meiya had said and realized she had a good point. After his surgery, the doctor did say rehab would be crucial to his recovery but that it would take time for him to gain back full use of his leg. He thought about how a baby had to learn to walk before it could run. He remembered when his nephew was learning to crawl; within days it seemed like he was walking. Running didnt come right away, Carlo remembered. He realized it was the same with his therapy. The maximum he had run in the past month was one mile on the treadmill, so he realized that Meiya was probably right. He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident. Since when did you get so smart, Dr. Meiya? he teased. Do you want to race to the next mailbox? Youre on! she challenged and took off running at full speed. Question 1 Part A What is a central theme of Racing to Race? (A) Good things always come to those who wait. (B) A close friend is good medicine. (C) Recovery from a setback takes time and patience. (D) Running a race is not always about winning. Question 2 Part B Which statement best shows how the theme identified in Part A is developed in the story? (A) Carlo pictures himself winning a big race on the school track team but then he realizes he may have developed asthma. (B) Carlo is discouraged that he has to rest after running a short distance, but Meiya reminds him that he has only just finished rehab. (C) Carlo realizes that he may not be able to compete on the school track team but also discovers that, with time, he will still be able to participate in a sport he loves. (D) Meiya knows that she is faster than Carlo, so she does her best to encourage him and also lets him win a race between them to boost his spirits.
