Answer:

80 tickets

Step-by-step explanation:

Adult tickets = A (cost $8)

student tickets = S (cost $4)

A = S + 20 (20 more adult tickets than student tickets)

Total amount = $880  

$8A + $4S = 880

New equation:  

$8(S+20) + $4S = 880  

$8S + 160 + $4S = 880

$12S = 720

S = 60

Next we find the adult tickets by substituting back:

A = S + 20

A = 60 + 20

A = 80

You are a host at a restaurant. You make $7.75 per hour. You work 17 hours each week and are paid biweekly. How much is your pay
Elodia [21]

Answer:

$263.50

Step-by-step explanation:

$7.75 (money earned per hour) x 17 (hours worked per week) = $131.75 per week. Biweekly means every two weeks so you're going to multiply the amount you earn per week by 2. The answer is then 263.50.

vova2212 [387]

Answer:

juliet collected 50 cans

Step-by-step explanation:

let x be rosanas cans

10+x+2x = 130

simplify

10 + 3x = 130

3x = 130 - 10 = 120

x = 120/3 = 40

rosanas cans = 40

juliets cans = 40 +10 = 50

santiagos cans = 50 x 2 = 100

but i think the question is wrong!!

A laboratory scale is known to have a standard deviation of Ï = 0.001 gram in repeated weighings. Scale readings in repeated wei
erica [24]

Answer:

the confidence interval for the true weight of the specimen is;

4.1593 ≤ μ ≤ 4.1611

Step-by-step explanation:

We are given;

Standard deviation; σ = 0.001

Sample size; n = 8

Average weight; x¯ = 4.1602

We are given a 99% confidence interval and the z-value at this interval is 2.576

Formula for confidence interval is;

CI = x¯ ± (zσ/√n)

Plugging in the relevant values, we have;

CI = 4.1602 ± (2.576 × 0.001/√8)

CI = 4.1602 ± 0.000911

CI = (4.1602 - 0.000911), (4.1602 + 0.000911)

CI ≈ (4.1593, 4.1611)

Thus, the confidence interval for the true weight will be expressed as;

4.1593 ≤ μ ≤ 4.1611

Where μ represents the true weight

A rectangular auditorium seats 1344 people. The number of seats in each rows exceeds the number of rows by 20. Find the number o
Tasya [4]
Let the number of rows be x

rows = x
seats in each row = x + 20

total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48  (rejected, answer cannot be negative) or x = 28

Therefore,
x = 28 
x + 20 = 48


Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
 
Ans:There are 48 seats per row

7. Use the properties of operations to simplify this algebraic expression. Rewrite the expression by following the directions in
Svetach [21]

Answer:

-x + -13

Step-by-step explanation:

Rewrite: 5(x – 4) + 3x – 9x + 7

Step 1: 5(x + –4) + 3x + –9x + 7

Step 2: 5x + -20 + 3x + –9x + 7

Step 3: 5x + 3x + –9x + -20 + 7

Step 4: -1x + -13

Step 5: -x + -13
