New York City is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 14 buses with 509 students. High School B rented and filled 12 vans and 10 buses with 472 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.​

Answers

Answer:

Step-by-step explanation:

Let's say :

v = number students in van, b = number of students in bus

From the info provided in the question:

High school A takes 3 vans and 14 buses for 509 students

We can write this as:

3v + 14b = 509

You can re-write this as :

3v = 509 - 14b

We also know High School B takes 12 vans and 10 buses for 472 students:

12v + 10b = 472

Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:

12v + 10b = 472

4(509 - 14b) + 10b = 472

2036 - 56b + 10b = 472

2036 - 46b = 472

2036 - 472 = 46b

1564 = 46b

Divide both sides by 46 to find "b".

b = 1564/ 46 =  34

Therefore the number of students that fit in each bus is 34.

So since we know b = 34, substitute b into the equation at the top:

3v = 509 - 14b

3v = 509 - 14(34)

3v = 509 - 476 = 33

Divide both sides by 3 to find "v".

v = 33/3 = 11.

Therefore the number of students in each van is 11.

The pizza shop is running a special: 2 medium pizzas
for $6.99 each. How much would it cost to by 12
pizzas?​

Answers

Answer:

41.94

Step-by-step explanation:

12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94

Answer:

$72.00

Step-by-step explanation:

Lets round $6.99 to $7.00. Now we have an easier number to work with.

To find the total price of 12 , we need to multiply $7.00 by 12.

⇒ $7.00 x 12 = $84.00

Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.

1 x 12 = 12

$84 - $12 = $72.00

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B ​

Answers

Answer:

A=50, B=4

A is directly proportional to the square root of B

name the constant 'k'

A = k*B^0.5

50 = k*4^0.5

50=2k

k=25

=> A =25 root B

i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)

A written in terms of B is 25√B.

What is direct and inverse proportion ?

In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.

According to the given question A is directly proportional to the square root of B.

∴ A = K[tex]\sqrt{B}[/tex]

Given when A = 50 B = 4.

50 = K[tex]\sqrt{4}[/tex]

50 = 2k

k = 25.

So, A =25√B.

Find the x and y intercept of the following equation 4x-10y=20

Answers

For the given linear equation we have:

y-intercept: y = -2x-intercept: x = 5.

How to find the intercepts for the linear equation?

Here we have a linear equation:

4x -10y = 20

First, let's find the y-intercept, this is the point with x = 0, so evaluating in that we get:

4*0 - 10y = 20

-10y = 20

y = 20/-10

y = -2

The x-intercept is what we get by evaluating in y = 0.

4x - 10*0 = 20

x = 20/4

x = 5

Pyramid of Species HELP MEEEEEEE!!!!!!!!!!!!!!!!Read this excerpt adapted from A Brave Lad. This story originally appeared in Chatterbox, a book of stories edited by J. Erskine Clarke.Which line from the story supports the idea that Fred is a courageous boy?It was Saturday afternoon when the boys of Wedderburn School went off as usual to swim their boats on a beautiful lake. Fred Langton had a new boat, which his grandfather had sent to him as a birthday present. It was a larger and better-constructed boat than any of the others. Each boy was, of course, eager that his own boat should win the race. Although all the boys admired Fred's boat and wished that they could have had one as good, they felt no grudge towards Fred himself. In fact, he was a general favorite in the school. He was kind-hearted, unselfish, and always willing to give anything that he had to his companions.I tell you, said Bill Cowan to his own particular chum, Joe Morris, that boat of Fred's will beat ours all hollow! I wish I had one as good!Well, suppose it does win, replied Joe Morris, I shall not grudge it to him, for Fred is no sneak; he is out-and-out the jolliest fellow in Wedderburn School.So he is, said Bill Cowan, and no mistake about it. Well, here we are at the lake, and now for some fun.On this particular Saturday, however, Fred was going to become famous in quite another way. The little boats were all in full sail, and the schoolboys were shouting with glee at the fun. Suddenly a fox-terrier took it into his head to chase the boats and show that he could swim as well as they could. Poor dog! It was quite true that he could swim. Unfortunately he got caught among weeds. He began struggling in the water and barking for help.Oh, I say, I can't stand this! cried Fred Langton; he will be drowned. I must go in and fetch him out!No, no! cried Bill Cowan; the lake is quite deep just at that place.Yes, I know it's deep, added Joe Morris, and, besides, you can't swim, Fred; don't be silly. Who cares for a dog being drowned?I do, for one, cried Fred, and dashing into the water he waded out to where the poor dog was half-standing, half-lying, among the choking weeds. Yes, the water was deep; but stretching out his arms he contrived to catch hold of the poor animal, and he quickly waded back to shore amid ringing cheers from all the people who had now gathered on the bank to watch the plucky lad. And whose was the dog? Nobody knew; it seemed, indeed, to have no owner and no home. But Fred and his companions carried it back with them to the school, and, after having told their tale, they begged the head master to keep it for himself. As Dr. Williams could not discover anything about the dog's ownership, he did keep it. So Fred's brave deed not only saved the animal's life, but procured a good home for it as well. what of the following are functions of lipids? choose three correct answers derive ideal gas equation for n mole of gas. which one of these situations is commonly caused by acid rain?a. people being poisoned by drinking water b. fish and birds in freshwater habitats dying offc. people receiving acid burns on there skind. whales and dolphins dying off in the oceans What value of x makes this equation true?need done fast please, offering 25 points!

Founded in 1983 by Nicolas Hayek, Swatch is now the worlds biggest watch maker. The company not only produces finished watches, it also produces jewelry, watch movements, and watch components. Indeed, Swatch Group supplies nearly everything used in the production of its 18 individual brands that includes icons like Omega and Harry Winston as well as more mainstream options like Tissot and Longines. In addition to its own line of products, Swatch Group sells watch components to third-party watchmakers and produces parts used for sport event timing. Swatch employs about 37,000 people across 37 global subsidiaries. With some 40 percent of the company still under the control of the Hayek family, Swatch focuses on diversity and culture. The Swatch Revolution combines Swiss excellence in watchmaking with quirky affordable plastic components. Swatch promotes its watches as a means of speaking without words. Wearers of Swatch watches are telling more than just time, they are telling the world something about themselves. Swatch even suggests that wearers share their individuality and preferences on Instagram by tagging #MySwatch. Discussion Questions 1. With the Hayek family controlling nearly 40 percent of The Swatch Group, how do you think the familys influence impacts the corporate culture in the company? What about the companys international culture being impacted by the Hayek family? 2. Many of the Swatch brands have become cultural icons among a strong core following of customers in the global marketplace. Some even talk about the "Swatch Revolution" that began when Nicolas Hayek founded the company. Why do you think Swatch has such a strong cultural following? 3. As mentioned, Swatch wants you to create your own unique way of accessorizing through its Swatch watch. Is a watch a way to show who a person is culturally? Does a watch get embedded into a persons culture? Can a watch create a cultural image?
