Answer:6

Step-by-step explanation:

The number of hours when the amount Andrew and dave pay for the rentals be equal will be 6 hours.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,

(y - 6)[(9 - 6) / (2 - 0)](x - 0)

y = 1.5x + 6

From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,

(y - 3) = [(5 - 3) / (1 - 0)](x - 0)

y = 2x + 3

The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,

2x + 3 = 1.5x + 6

0.5x = 3

x = 6 hours

The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Answer:

(1, -7)

Step-by-step explanation:

the difference between -4 & 6 is 10 so you add 5 (half) to -4 or subtract from 6, this gives you 1

you do the same for -9 and -5, the midpoint for those being -7, I hope this helps

Answer:

n is 18

Step-by-step explanation:

Answer:

24 - n = 6

Figure out what plus 6 will give you 24.

Or add 24 and 6 and use the sum as the fill-in for n.

24 + 6 = 30.  

Replace the variable.

30 (n) - 24 = 6.

Answer:

5184 cm³

Step-by-step explanation:

12 × 16 × 27 = 5184

Answer:It is 154 square inches. and 38 width

Step-by-step explanation:

Answer:

{5 ft, 18 ft}, {1 ft, 90 ft}, {9 ft, 10 ft}

Step-by-step explanation:

Represent the length and width by L and W respectively.

Then one requirement may be expressed as L > W.

The other requirement is L * W = 90 ft^2.

Let's temporarily replace W in this equation with L:

L^2 = 90 ft^2, so that L must be the positive square root of 90 ft^2:

L = √(90 ft^2) ≈ 9.5

Since L must be greater than W, we can write L > 9.5 ft.  The nearest integer L would be 10, in which case the nearest integer W would be 9, which means that the area of the stage would be 90 ft^2 (as required).

{9 ft, 10 ft} are possible whole number measurements for L and W.  Here W < L, as required, and L and W are both integers.

{5 ft, 18 ft} is another possible set of measurements.

So is {1 ft, 90 ft}.

Step-by-step explanation:

We have a right triangle with long side of 11in and smaller sides 14in/2=7in and h.

We know that

[tex]h^2 + (7in)^2 = (11in)^2\\h^2 = 121in^2 - 49in^2 = 72in^2\\h = \sqrt{72}in[/tex]

Step-by-step explanation:

1. Exponentially solve equation

A=249e-0.0015t as t = 43 years (Unless conversion to seconds)

A≈676.2

2. Solve graphically = intersect = (43, 676.2) x axis is time y axis is amount.

Answer:

$1100

Step-by-step explanation:

Let the total budget = b

amount spent on props + amount spent on equipment = total budget

If 37% of the budget was spent on equipment

The percentage spent on props = 100% - 37% = 63%

63% of the total budget is $693

the above sentence presented as an equation gives :

63/100 x b = 693

to find b, divide both sides of the equation by 100/63

b = $1100

Answer:

This question may be incomplete, so i will answer this in a really general way.

We have the equation:

17*y = 24*x - 582

Where this represents the amount of money made from the main floor and balcony tickets, where i suppose that 17*y represents the money and x is the number of tickets sold.

We are subtracting 582 from the right side, this may be related to the cost of the tickets.

Like in the profit equations:

Profit = revenue - cost

Then we can have:

profit = 17*y

revenue = 24*x

cost = 582

Answer: 100.5 square feet

Step-by-step explanation:

To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]

The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]

where r is the radius of sphere.

Putting the values we get:

surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]

Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet
