3) How many cubic feet of water can the
following in-ground swimming pool hold?

The factors of the given quadratic expression are (3x+4) and (2x-15)

From the question, we are to determine the factors of 6x²+37x-60

The given quadratic expression can be factored as shown below

6x² + 37x -60

This becomes

6x² -45x + 8x -60

3x(2x-15) +4(2x-15)

Then,

(3x+4)(2x-15)

Hence, the factors of the given quadratic expression are (3x+4) and (2x-15). The correct option is the second option (3x+4) and (2x-15)

Step-by-step explanation:

The area of the rectangular roof (both sides of the roof) = 1,360 ft²

Cost to cover both sides = $1,020

The area of a rectangle = (length)(width)

Area of both sides of the roof = 2(area of rectangle) = 2(40×17) = 1,360 ft²

Cost to cover both sides = 1,360 × 0.75 = $1,020

Answer:

x = 2 ; y = 12

Step-by-step explanation:

2x + 3y = 40

+ -2x +2y = 20

You solve for one of the variables by cancelling out one and making one the subject.

2x + 3y = 40.

+ -2x +2y = 20

5y = 60

5y/5 = 60/5

y = 12

Next, you solve for X by replacing the value of y in any of the equations.

2x + 3y = 40

2x + 3(12) = 40

2x + 36 = 40

2x = 40 - 36

2x = 4

2x/2 = 4/2

x = 2

To prove the equations are set, replace the values of X and Y in one of the equations.

2x + 3y = 40

2(2) + 3(12) = 40

4 + 36 = 40

40 = 40

Step-by-step explanation:

The  coordinates of E(4a, 0).

A midpoint is a point in the middle of the line connecting two points that lies between them. The midpoint is a point that lies in the middle of the line and is equidistant from the two points if a line is drawn to connect them.

The midpoint between two points whose coordinates are known to us can be found using the midpoint formula. If we know the coordinates of the other endpoint and the midpoint, we can also use the midpoint formula to determine the coordinates of the endpoint.

Given coordinates

A(-3a, -2b),  D(a, -2b), C(5a, -2b) and B(3a, 2b)

to find the coordinates of E,

and E is midpoint of B and C

for coordinates of midpoint is (x, y) = [(x₂ + x₁)/2, (y₂ + y₁)/2]

here B  = (3a, 2b) = (x₁, y₁)

and C = (5a, -2b) = (x₂, y₂)

x = (5a + 3a)/2 = 8a/2 = 4a

y = (-2b + 2b)/2 = 0/2 = 0

E(4a, 0)

Hence coordinates of E are (4a, 0).

Step-by-step explanation:

the upper (smaller) triangle and the complete triangle are similar.

that means the angles in both triangles are the same. and the lengths of all corresponding pairs of sides correlate with the same scaling factor.

therefore,

(8x - 10) / (8x - 10 + 18) = 25 / (25 + 15)

(8x - 10) / (8x + 8) = 25 / 40 = 5/8

8(8x - 10) = 5(8x + 8)

64x - 80 = 40x + 40

24x = 120

Solve the system of equations by substitution to find the intersection

Answer:

4 hours

Step-by-step explanation:

First, create a linear equation for Carlos using the graph.

Two points on the line:  (0, 2) and (1, 10)

[tex]\implies \sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{10-2}{1-0}=8[/tex]

Use the point-slope equation with the found slope and one of the points:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-2=8(x-0)[/tex]

[tex]\implies y=8x+2[/tex]

Now equate the equations for Mary Ann and Carlos, and solve for x:

[tex]\implies 6x+10=8x+2[/tex]

[tex]\implies 8=2x[/tex]

[tex]\implies x=4[/tex]

Therefore, Mary Ann and Carlos have saved the same amount after 4 hours work.

Answer:

1134

Step-by-step explanation:

Formula for diameter=2 x r

(π is 3.14)

Formula for area= π x r^2

So all you basically have to do is go backwords with the first one then plug the radius into the second one normally

38/2=19

Now just plug it into your second equation

π x 19^2=1134.11494795

And lastly round that to 1134, easy! :)

Answer:

centre : (4;-5)

radius : 2

Explanation:

The x coordinates of points A and B are 2 and -2 respectively. Add them up and divide by 2 and we would get (A+B)/2 = (2+(-2))/2 = 0/2 = 0.

The x coordinate of the midpoint is 0.

The y coordinate of the midpoint follows the same idea, but we focus on the y coordinates of course. You should find the y coordinate of the midpoint is 0.

The midpoint is at (0,0) as the diagram shows.

2x + 13 = 0

Reorder the terms:

13 + 2x = 0

Solving

13 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + 2x = 0 + -13

Combine like terms: 13 + -13 = 0

0 + 2x = 0 + -13

2x = 0 + -13

Combine like terms: 0 + -13 = -13

2x = -13

Divide each side by '2'.

x = -6.5

Simplifying

x = -6.5

Step-by-step explanation:

The maximum number of months the computer could be kept so that it is cheaper to rent than to buy is 10 months.

The first step is to determine the month in which the two options would have the same cost. The equation that can be used to determine this value is:

$1890 = $900 + 90t

90t = 1890 - 900

90t = 990

t = 990 / 90

t  = 11 months

The maximum number of months = 11 months - 1 = 10 months
