Answer: 1) $189

2) weekdays=$19.5, weekends=$35

Step-by-step explanation:

Problem 1

Pants: 6x12=60

Shirts: 21x3=63

Shoes: 11x6=66

Total: 60+63+66= $189

Problem 2

Weekday: 25x0.30=7.5 7.5+12= $19.5

Weekend: 40x0.50=20 20+15=$35

I will do 12 only.

Let x = cost per pants.

A function for pants is f(x) = 5x.

Let y = cost per shirts.

A function for shirts is f(y) = 3y.

Let z = cost per pair of shoes.

A function for pair of shoes is f(z) = 11z.

For selling 12 pants:

f(12) = 5(12) = $60.

For selling 21 shirts:

f(21) = 3(21) = $63

For selling 6 pairs of shoes:

f(6) = 11(6) = $66

Let S = what she earned in total sales.

S = $60 + $63 + $66

S = $189

30 points and brainliest!! HELP NOW

Answer:

First question

a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

y = 2x² + 4 ⇒ second answer

Third question

No of the choices correct ⇒ fourth answer

Step-by-step explanation:

First question

∵ f(x) = x² + 6

- It is a quadratic function with general form ax² + bx + c

- Its vertex is (h , k), where h = -b/2a and k = f(h)

∵ a = 1 , b = 0 , c = 6

∴ h = 0/2(1) = 0

∴ f(0) = 0² + 6 = 6

∴ a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

- If the function f(x) translated vertically up

by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down

by k units, then the new function g(x) = f(x) – k

∵ y = 2x²

∵ y is shifted 4 units up

∴ k = 4

∴ y + 4 = 2x² + 4

∴ y = 2x² + 4 ⇒ second answer

Third question

∵ y = -2x² + 3

- It is a quadratic equation with general form ax² + bx + c

- It represented graphically by parabola

- If a is positive the parabola opens upward

- If a is negative the parabola opens downward

∵ a = -2

∴ The parabola opens downward

∴ No of the choices correct ⇒ fourth answer

John is selling tickets to an event. Attendees can either buy a general admission ticket, x,

Masteriza [31]

John sold 18 general admission tickets and 11 VIP tickets.

Step-by-step explanation:

Given,

Cost of each general admission = $50

Cost of each VIP ticket = $55

Total tickets sold = 29

Total revenue generated = $1505

Let,

x represent the number of general admission tickets sold

y represent the number of VIP tickets.

x+y=29 Eqn 1

50x+55y=1505 Eqn 2

Multiplying Eqn 1 by 50

$50(x+y=29)\\50x+50y=1450\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(50x+55y)-(50x+50y)=1505-1450\\50x+55y-50x-50y=55\\5y=55$

Dividing both sides by 5

$\frac{5y}{5}=\frac{55}{5}\\y=11$

Putting y=11 in Eqn 1

$x+11=29\\x=19-11\\x=18$

John sold 18 general admission tickets and 11 VIP tickets.

navik [9.2K]

Let the boy be B and the girl be G
there are six possible outcomes
BGG, GBB, GBG, BGB, BBB, and GGG
therefore the probability of getting one boy and two girls is $\frac{1}{6}$
also the probability of getting 3 girls is $\frac{1}{6}$
