Step-by-step explanation:

h=2b, (bh/2)=100, bh=100, b^2=100, b=10

Answer:

Part A)

[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]

Part B)

Flight X sold 15 tickets and Flight Y sold 105 tickets.

Part C)

Flight X made $1,350 and Flight Y made $26,250.

Step-by-step explanation:

Let the amount of tickets sold by Flight X be represented by x and the amount of tickets sold by Flight Y be represented by y.

Part A)

The airline sold 120 tickets in total. Hence:

[tex]x+y=120[/tex]

Each x ticket costs $90 and each y ticket costs 250. The total income was $27,600. Thus:

[tex]90x+250y=27600[/tex]

Our system of equations is:

[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]

Part B)

Solve the system of equations. We can use substitution. From the first equation, subtract y from both sides:

[tex]x=120-y[/tex]

In the second equation, we can divide everything by 10 and substitute in x:

[tex]9(120-y)+25y=2760[/tex]

Simplify:

[tex]16y+1080=2760[/tex]

So:

[tex]y=105\text{ tickets}[/tex]

Using the equation above:

[tex]x=120-(105)=15\text{ tickets}[/tex]

Flight X sold 15 tickets and Flight Y sold 105 tickets.

Part C)

Since each ticket of Flight X sold for $90 and Flight X sold 15 tickets, Flight X made $1,350.

Then it follows that Flight Y made $26,250.

The answer is below

Step-by-step explanation:

Breakeven point is the point of balance where their is neither a loss or a profit. At the breakeven point, the revenue gotten from the sell of goods is equal to the cost of production of the goods, hence the profit is zero.

Given the profit function:

P=-2b² + 14b - 20

At breakeven P = 0, hence:

0 = -2b² + 14b - 20

-2b² + 14b - 20 = 0

-2b² + 10b + 4b - 20 = 0

-2b (b - 5) + 4(b - 5) = 0

(b - 5)(-2b + 4) = 0

b - 5 = 0; or -2b + 4 = 0

b = 5; or b = 2

Since b is in thousands, hence the company breaks even when the number of skateboards produced is either 2000 or 5000

Answer:

[tex]6[/tex]

The answer is C:6

The probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.

Let us find the individual probabilities.

P(Large | Cold) = 5/25 = 0.2 (out of 25 cold drinks, 5 were large)

P(Cold) = (8+12+5)/100 = 0.25 (out of 100 orders, 25 were cold)

P(Large) = (22+5)/100 = 0.27 (out of 100 orders, 27 were large)

Now we can plug these values into Bayes' theorem:

P(Cold | Large) = 0.2 × 0.25 / 0.27

P(Cold | Large) = 0.1852

Therefore, the probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.

Answer:

(3, -5)

Step-by-step explanation:

So, there are three steps in finding the vertex.

We need to first find a, b and c. a is the x^2 coefficent, b is the x cofficent, and c is the number value. In this case:

a=1, b=-6, and c=4

To find the x value of the vertex, plug in a and b into the formula:

-b/2a = x coord of vertex:

-*-6/2*1

=

6/2

=

3

So the x coordinates of the vertex is 3.

To find the y cooridnates, plug in 3 into the orginal equation:

[tex](3^2)-(6*3)+4[/tex]

=

[tex]9-18+4[/tex]

=

[tex]-5[/tex]

So -5 is the y coordinates of the vertex.

Answer:

(3, -5)

Hope this helps!

Going over steps:

Step 1 - Find values a b and c: a=x^2 coefficent. b=x coefficent. c=number

Step 2 - Plug in a and b into -b/2a

Step 3 - Plug in x into equation

A ball was kicked into the air from a balcony 20 feet above the ground, and the ball's height above the ground, in feet, t seconds after the ball was kicked was h(t) = 20 - 16t2 + 32t.

Answer:

Step-by-step explanation:

Smaller Canister:

Height, h = 12cm

Diameter = 9cm

Radius, r = 4.5 cm

[tex]Volume = \pi r^2h\\[/tex]

           [tex]=\pi \times 4.5^2 \times 12\\\\=243 \pi \ cm^3[/tex]

[tex]Surface \ area = 2 \pi r(r + h)\\[/tex]

                    [tex]=2 \times \pi \times 4.5 ( 4.5 + 12)\\\\= \pi \times 9(16.5)\\\\=148.5 \ cm^2[/tex]

Larger Canister:

Measures double the smaller canister, that is

height, H = 24 cm

Diameter = 18cm

Radius, R = 9cm

[tex]Volume = \pi R^2 H\\[/tex]

           [tex]= \pi \times 9^2 \times 24\\\\= \pi \times 81 \times 24 \\\\= 1944 \pi[/tex]

[tex]Surface \ area = 2 \pi R(R+ H)[/tex]

                    [tex]= \pi \times 2 \times 9 ( 9 + 24) \\\\= \pi \times 18(33)\\\\=594 \pi \ cm^2[/tex]

Comparing results :

[tex]Volume_{small} = \pi r^2 h\\\\Volume_{large} = \pi R^2 H = \pi(2r)^2(2h) = \pi(4r^2)(2h)= 8 \pi r^2h = 8 \times volume_{small}[/tex]

Therefore, volume of larger canister is 8 times the volume of smaller canister.

[tex]Surface\ area _{larger} = 2 \pi R(R + H) = 2 \pi(2r)((2r+2h))\\\\[/tex]

                                                   [tex]=2 \ pi \times 2r \times 2 (r+ h)\\\\= 4 \times 2\pi r(r+ h) \\\\= 4 \times surface\ area_{smaller}[/tex]

Therefore, surface area of larger canister is 4 times the surface area of smaller canister.

Answer:

f(x) = 3x + 50 is the equation in function notation.

(22, 116) is the ordered pair for 22 deliveries.

Step-by-step explanation:

First, create the equation. Let x represent how many deliveries he makes.

Since he makes $3 on each delivery, the total amount he makes from deliveries can be represented by 3x.

He also makes $50 a shift, so add this to 3x in the equation:

f(x) = 3x + 50 is the equation in function notation.

Find how much he will make if makes 22 deliveries. Plug in 22 as x:

f(x) = 3x + 50

f(22) = 3(22) + 50

f(22) = 66 + 50

f(22) = 116

So, he will make $116.

As an ordered pair, the solution is (22, 116).

Answer:

f(x) = 3x + 50

Step-by-step explanation:

If he makes $50.00 a shift, and $3.00 for each delivery, and he makes 22 deliveries in one shift then the equation (in function notation) would be f(x) = 3x + 50.  and the solution to the equation is 116.

Explanation:

Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles

The total area is therefore 32+9 = 41 cm^2

You can say "square cm" or "sq cm" in place of the "cm^2".

You can solve this in two different ways. In both ways, however, use the formula for the area of a square/rectangle. The formula is:

Area = Length x Width

A = L x W

To solve, divide the shape given into two rectangles. Then, find the areas of the two different rectangles and add them
