When their report cards came back, Pete, Chris, and Dina realized that the number of A's they each received was in the ratio 4:2:5. If Pete got 14 more A's than Chris, how many A's did Dina get?

Answers

Answer:

The number of A's Dina got = 5/11 × 77 = 385/11 = 35

Step-by-step explanation:

The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.

Let the total number of A's = y

Total from ratio = 4 + 2 + 5 = 11

chris A's = 2/11 × y

pete's A's = 2/11 × y + 14 = 4/11 × y

pete's A's

2/11 y + 14 = 4/11 y

14 = 4/11 (y) - 2/11 (y)

14 = 2/11 (y)

cross multiply

2y = 14 × 11

divide both sides by 2

y = 154/2

y = 77

Total number of A's = 77

The number of A's Dina got = 5/11 × 77 = 385/11 = 35

HELP FAST PLEASE What is the value of the function at X=-3?
O y = 4
O y = 0
O y = 3
0y=-3

Answers

Answer:

To determine the value of the function at x = -3, we need to substitute -3 into the given function and evaluate it. Let's go through each option one by one:

1. y = 4: If this is the function, then substituting x = -3 would give us y = 4. However, this option does not match the given function.

2. y = 0: Substituting x = -3 into this function would give us y = 0. However, this option does not match the given function either.

3. y = 30: Substituting x = -3 into this function would give us y = 30. However, this option does not match the given function.

4. y = -3: Substituting x = -3 into this function would give us y = -3. This option matches the given function, so the value of the function at x = -3 is indeed y = -3.

Therefore, the correct answer is:

y = -3

The combined cost of one advance ticket and one same-day ticket to a show was $50. it is known that 17 advance tickets were sold and 48 same-day tickets were sold, for total receipts of $1842. what was the price of each kind of ticket?

Answers

1 advance + 1 same-day = $50
17 advance + 17 same-day = $50 x 17 = $850

$1842 - $850 = $992
48 - 17 = 31 same-day

31 same-day = $992
1 same-day = $32

1 advance + 1 same-day = $50
1 advance + $32 = $50
1 advance = $50 - $32 = $18

Answer: same day ticket costs $32 and advance-day ticket costs $18.

A same day ticket costs $32 and an advance day ticket costs $18. Hope this helpd.
