Answers

Answer 1

Answer:

P  2.680          S  2.920     T    4.200

Step-by-step explanation:

 S = seconde    

 Premiere =  S-240

Troisieme = 3/4( 2S -240)

S + S-240 + 3/4(2S-240) = 9800

Multiplie  tout par 4 pour eliminer la fraction

4S + 4S -960 + 6S - 720  =  39200

14 S = 40.880

S = 2.920

P = 2.920-240 = 2.680

T =3/4(5.600) = 4.200

2.920  + 2.680 + 4.200  = 9.800

A corporate team-building event costs $2 for every attendee. Write an equation that shows the relationship between the attendees x and the cost y.

Write your answer as an equation with y first, followed by an equals sign.

Answers

Answer:

y = 2x

Step-by-step explanation:

Tony's class needs more than $500 for the school dance.
So far, they have raised $200. They plan to have a car
wash, charging $8 a car, to raise more money. Tony
solved the inequality 8x + 200 > 500, and determined
that if they wash 37 cars, they will have enough money.
Is he correct? Explain.
(Please reply with sample answer if there is one!!)

Answers

Answer:

yes hes correct.

Step-by-step explanation:

37x8=296. 296+200= 596. 596>500

Answer:

No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5 Since the class must wash a whole number of cars, they need to wash at least 38 cars.

If your Gross Pay for a week at work is $340, and you have to pay 23% in taxes, what is your Net Pay (what you take home)?

Answers

Answer:

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

B) (4y – 49) units by (y + 1) units

C) (2y – 7) units by (2y + 7) units

D) (y – 7) units by (4y + 7) units

Answers

The dimensions of the rectangle are (2y – 7) units by (2y + 7) units

Area of a rectangle

The formula for calculating the area of a rectangle is expressed as

Area = length * width

Given the following parameter

Area = .4y² - 49

Factorize the area

Area = (2y)² - 7²

Using the difference of two square

Area = (2y - 7)(2 y + 7)

Hence the dimensions of the rectangle are (2y – 7) units by (2y + 7) units

Carlos makes a 15% commission on the mattresses that he sells to customers. If he sells $8,500 worth of mattresses, what is his commission?

Answers

Answer:

Net commission= $1,275

Step-by-step explanation:

Giving the following information:

Sales= $8,500

Sales commission rate= 15% = 0.15

Net commission= sales * Sales commission rate

Net commission= 8,500 * 0.15

Net commission= $1,275

Find the length of each diagnol and the area

Answers

Answer:

The length of diagonal BD is 11·(1 + √3)

The length of diagonal AC = 22

Step-by-step explanation:

The given data are;

Quadrilateral ABCD = A kite

The length of segment AD = 22

The measure of ∠DAE = 60°

The measure of ∠BCEE = 45°

Whereby, triangle ΔADE = A right triangle, and DE is the perpendicular bisector of AC, by trigonometric ratio, we have;

AE = EC

DE = 22 × sin(60°) = 11·√3

AE = 22 × cos(60°) = 11

∴ AE = EC = 11

BE = EC × tan(∠BCE) = 11 × tan(45°) = 11

The length of the diagonal BD = BE + DE (By segment addition property)

∴ BD = 11 + 11·√3 = 11·(1 + √3)

The length of diagonal BD = 11·(1 + √3)

The length of diagonal AC = AE  + EC

∴ AC + 11 + 11 = 22

The length of diagonal AC = 22.
