A plane traveled 696 miles each way to New York City and back. The trip there was with the wind. It took 6 hours. The trip back was into the wind. The trip back took 12 hours. What is the speed of the wind?

A. Wind is 29 mph
B. Wind is 87 mph
C. Wind is 46 mph
D. Wind is 15 mph

Answers

Answer: A. Wind is 29 mph

Step-by-step explanation:

We can define:

Sp = speed of the plane

Sw = speed of the wind.

When the plane travels in the same direction that the wind flows, we can write the total speed as:

S = Sp + Sw

And when the plane travels against the flow of the wind, we can write:

S = Sp - Sw.

Now, we have the relation:

Distance = Speed*Time.

We know that:

Distance = 696 mi.

"The trip there was with the wind. It took 6 hours. "

then:

696mi = (Sp + Sw)*6h

"The trip back was into the wind. The trip back took 12 hours."

696mi = (Sp - Sw)*12h.

Then we have the system of equations:

696mi = (Sp + Sw)*6h

696mi = (Sp - Sw)*12h.

First, let's isolate one of the variables in one of the equations, i will isolate Sp in the first eq:

696mi/6h = Sp + Sw

116 mph - Sw = Sp.

Now we can replace this into the other equation:

696mi = (116mph - Sw - Sw)*12h

Let's solve this for Sw, that is the value that we want to find:

696mi/12h = (116mph - 2*Sw)

58mph - 116mph = -2*Sw

-58mph/-2 = Sw = 29mph.

The correct option is A.

6 Friends all use two dollars off coupon to buy them selves movie tickets they spend a total of $42 what is the price of one movie ticket without the coupon

Answers

Answer:

The answer is $7

Step-by-step explanation:

The answer is $7 because $42 divided by 6 = 7.

Answer:

The price of one movie ticket without a coupon would be $9.

Step-by-step explanation:

one movie ticket: x

$42 = 6(x- 2)

$42 = 6x- $12

Move the 12 to the other side.

 42  = 6x  - 12

+ 12            +12

____________

 54  = 6x

Now divide 6 from both sides.

  [tex]\frac{54}{6}[/tex] = [tex]\frac{6x}{6}[/tex]

You have $135 in a savings account and save $12 per week. Your friend has $95 in a savings account and saves $20 per week. How many weeks will it take for you and your friend to have the same balance?

Answers

Answer:

It will take 5 weeks for you and your friend to have the same balance

Step-by-step explanation:

Let

Your savings expression be

135 + 12x

Your friends savings expression

95 + 20x

Where,

x = number of weeks for you and your friend to have the same balance

Equate the two expressions

135 + 12x = 95 + 20x

Collect like terms

135 - 95 = 20x - 12x

40 = 8x

Divide both sides by 8

40/8 = x

x = 40/8

= 5

x= 5 weeks

Check

Your savings expression

135 + 12x

135 + 12(5)

=135 + 60

= $195

Your friends savings expression

95 + 20x

95 + 20(5)

= 95 + 100

= $195

Therefore, It will take 5 weeks for you and your friend to have the same balance

What is the value of x? x=int(13.25 + 4/2) *​

Answers

15.25 is the answer of the question

The value of x is x = int(13.25 + 4/2) is 15

Integers are negative or positive whole numbers. Given the expression for x,  x=int(13.25 + 4/2)

This means that we are to express  the result of x as an integer

Solving the expression 13.25 + 4/2

[tex]=13.25+\frac{4}{2} \\=13.25 + 2\\=15.25\\[/tex]

In order to convert this result into an integer, we will approximate it to the nearest whole number. Hence:

[tex]x=int(15.25)\\x \approx 15[/tex]

This shows that the value of x is x = int(13.25 + 4/2) is 15

Hillside Travel pays its employees $10 per hour plus 8% commission on all trips booked. Tyrus worked 20 hours last week and booked trips amounting to $2,100. What was his gross pay for last week? *

Answers

Answer:

$368

Step-by-step explanation:

Well, if they pay their employees $10 per hour, and Tyrus worked 20 hours, then we have a base amount of 200, as 10*20=200. Next, we need to think about the 8% commission from 2100, so we multiply 2100*.92 to get 1932 so 2100-1932=168. So, to get the gross pay, you add the base amount, 200, and the commission, 168, together to get $368. Tyrus got a gross pay of 368 dollars last week.

Answer:

No

Step-by-step explanation:

In a single year, there are 12 months. 1 month=1 inch.

12 x 1 inch is 12 inches.

12 is greater than 4, so the answer is not a proportional relationship.

12 is greater than 4, so the answer is not a proportional relationship.

Answers

Answer:

3x + 24

Step-by-step explanation:

Given that;

Company owns two manufacting plants with the following daily production levels :

PLANT A:

8x + 17 widgets

PLANT B:

5x - 7 widgets

Where x = minimum quantity

How many more items does the first plant produce daily than the second plant?

Subtract the Plant B's production level from plant A

8x + 17 - (5x - 7)

8x + 17 - 5x + 7

Collecting like terms

A recipe for fruit calls for 2 cans of pineapple juice and 3 cans of orange juice. Hiri is making a large batch for a community function and uses 72 cans of orange juice. How many cans of pineapple juice should he use?

Answers

Answer:

48  cans of pineapple juice he should use.

Step-by-step explanation:

This, is a problem of ratio where we have to use the concept

a:b = c:d which can be also written as

a/b = c/d

______________________________________________________

According recipe

we find ratio of pineapple and orange juice

amount pine apple juice :  amount of orange juice = 2 cans : 3 cans

Thus, ratio of pineapple and orange juice = 2:3

___________________________________

Given that this recipe is used for making juice in large batch for a community function

Given

amount of orange juice = 72 cans

let the amount of  pine apple juice be x

ratio of pineapple and orange juice in this case

amount pine apple juice :  amount of orange juice = x cans : 72 cans

ratio of pineapple and orange juice in this case= x : 72

since recipe used is same.

ratio will be same in both case that in recipe ratio and large batch preparation for community function

Thus,

x:72 = 2:3

which can also be written as

x/ 72 = 2/3

x = 2/3 * 72 = 48

Thus, 48  cans of pineapple juice he should use.
