Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.

Answers

Answer 1

Answer:

Answer:

adult tickets 6.9

children tickets 3.9

Step-by-step explanation:

3x + y = 24.60 L1

5x + 4y = 50.10 L2

5L1 - 3L2

15x + 5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

A sugestion: calculate m, c, d from:

3m + 4c + 7d = 5.45;
4m + 2c + 8d = 5.30;
2m + 5c + 6d = 5.15;

Then, calculate 10 - (4m + 2c + 9d);

a rainstorm produced a rainfall of 2 inches per hour how many hours would it take to get a rainfall amount of one foot

Answers

There are 12 inches in one foot. If it rains 2 inches per hour, that means it would take 6 hours to rain 12 inches, or one foot.

6 hours x 2 inches/hour = 12 inches or 1 foot

12 inches in 1 ft. 2 inches per hour. 12 divided by 2 = 6hrs.

If you have a semi-circle with a diameter of 8.6ft, what's the semi-circles area? Use the formula $\pi r^(2)$

Answers

So,

The diameter is 8.6ft. We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

$\pi r{2}$

$\pi 4.3^(2)$

$\pi 18.49$

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²

Which inequality matches the graph? (2 points)A) −2x + 3y > 7

B) 2x − 3y < 7

C) −3x + 2y > 7

D) 3x − 2y < 7

Answers

Answer:

D) 3x − 2y < 7

Step-by-step explanation:

We note that the x- and y-intercepts are about 2.3 and -3.5, respectively.

In "intercept form," the equation of the line can be written ...

x/x-intercept +y/y-intercept = 1

Using the given intercepts, this is ...

x/2.3 +y/(-3.5) = 1

The answer choices suggest that we should multiply this by 7. When we do, we get ...

3x -2y = 7 . . . . the equation of the boundary line

The next trick is to figure the comparison symbol. We note that x-values are less than those on the line, and y-values are greater than those on the line. It is convenient to consider the term with a positive coefficient, so we don't get confused with minus signs and reversed comparisons.

As we said, x-values are less than those on the line, so the shaded area is ...

3x -2y < 7 . . . . matches choice D

Answer:

D) 3x − 2y < 7

Took the test and got it right :)
