The perimeter of a rectangular house is given by the formula P = 2L+
2W, where L represents the length of the house and W represents the
width of the house.
Rewrite the equation to determine the width of the house when the
perimeter is 2,000 feet and the length is 600 feet.

The answer is A.

I used a graphing calculator.

Answer:

the first one

Step-by-step explanation:

slope: use rise-over-run theorem. the slope of the graph rises -2 for every 1 unit over, so slope is -2x

intercept: the line crosses the y-axis at y=3, hence +3

put it together: y=-2x+3

Answer:

It is not.

Step-by-step explanation:

[tex]15^{2}[/tex]+[tex]7^{2}[/tex]=225+49=274

[tex]16^{2}[/tex]=256

274≠256

Answer:

No, this triangle is not a right triangle

Step-by-step explanation:

If (7 cm)^2 + (15 cm)^2 = (16 cm)^2, then this is a right triangle, by the Pythagorean Theorem.  Otherwise it is not.

15^2 + 7^2 = 225 + 49 = 1225 = 35^2.  This is FALSE, and so:

No, this triangle is not a right triangle

Answer:

g(n) = [tex]\frac{11+5n}{3}[/tex]

Step-by-step explanation:

Given

3m - 5n = 11

Rearrange making m the subject

Add 5n to both sides

3m = 11 + 5n ( divide both sides by 3 )

m = [tex]\frac{11+5n}{3}[/tex] , thus

m = g(n) = [tex]\frac{11+5n}{3}[/tex]

Answer:

Option B

Step-by-step explanation:

-8x + 4y = 20

[tex]-8x+8x+4y=20+8x \leftarrow \text {Addition Property of Equality.}\\4y=20+8x\\\\\frac{4y}{4}=\frac{20+8x}{4} \leftarrow \text {Division Property of Equality.}\\y=5+2x\\\boxed {y=2x+5}[/tex]

Option B should be the correct answer.

The value of JW is 14 units.

A triangle is a polygon with 3 sides. The area of a triangle with base b and height h is given by A = (1/2)bh.

Given that, JB is the median of the triangle and JW = 6x + 2 and JB = 10x + 1.

The distance between the centroid and a vertex of a triangle is 2/3 of the length of the median, therefore, it follows:

JW = (2/3)JB

Substitute the values:

6x + 2 = (2/3)(10x + 1)

18x + 6 = 20x + 2

2x = 4

x = 2

Substitute x = 2 into the expression for JW:

JW = 6(2) + 2

JW = 14

Hence, the value of JW is 14 units.

Correct option: second one -> 24 square units

Step-by-step explanation:

First we need to find the length of each side of the trapezoid, and we do that finding the distance between points:

AB = sqrt( (-1 - (-3))^2 + (2 - (-2))^2) = 4.4721

BC = sqrt( (3 - (-1))^2 + (2 - 2)^2) = 4

CD = sqrt( (5 - 3)^2 + (-2 - 2)^2) = 4.4721

DA = sqrt( (-3 - 5)^2 + (-2 - (-2))^2) = 8

The points B and C have the same y-coordinate, and the points D and A also have the same y-coordinate, so they are the bases of the trapezoid.

The height of the trapezoid is the difference in y-coordinate of points B and A:

height = 2 - (-2) = 4

So the area of the trapezoid is:

Area = (BC + DA) * 4 / 2 = (4 + 8) * 2 = 24 square units

Correct option: second one

1a) C, D, E   is over 600 cubic inches.

1b) x4.8 greater  The sphere is x4.8 greater than the first cone.

Step-by-step explanation:

A) Smaller Right cylinder V≈565.49   cubic inches

B) Smaller cone V≈188.5  cubic inches

C)  Cylinder right prism V≈1696.46  cubic inches

D) Right circular cone V≈565.49     cubic inches

E ) Sphere V≈904.78 cubic inches

1b) Volume of sphere/volume of smaller cone

is 904.78/188.5=  4.7998938992  =  x4.80 greater.

Answer:

x > 0

Step-by-step explanation:

Division by zero is not defined.  Therefore, x must be greater than zero.  Also:  The square root function is defined only for x greater than zero or equal to zero.  Together these restrictions tell us that the domain is (0, infinity ).

Answer:

Step-by-step explanation:

Area of circle = πr²  = 15 m²

Volume of Cylinder = πr²h

                                = 15 * 3

                                = 45 m³

Volume of Cone = (1/3)πr²h

[tex]=\frac{1}{3}*15*3\\\\[/tex]

= 15 m³

Answer: x = 2

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(x) which is 4x and 4(6) which is 24.

So our equation now reads 4x + 24 = 32.

Solving from here, we subtract 24 from both sides to get 4x = 8.

Then divide both sides by 4 to get x = 2.

Answer:

y=-3/2x-.5

Step-by-step explanation:

(5,-4) and (1,-2)

Step 1: find slope:

-4-2/5-1=-6/4=-3/2

y=mx+b

y=-3/2x+b

2.: Plug in point

(1,-2)

-2=-3/2*1+b

-2=-3/2+b

-2+3/2=b

b=-.5

Answer:

254.34 cm^2

Step-by-step explanation:

Volume of cylinder = [tex]\pi r^{2} h[/tex]

We know that the diameter is 6, which means that the radius is 3 cm.

Now, it also tell us that that the height is triple the radius, this means that we multiply it by 3. Therefore, the height is 9 cm.

Now we know r = 3 cm and h = 9 cm, pi is assumed to 3.14 as well.

Substituting into the formula we will end up with 254.34 cm^2.

The answer would look something like this:

[tex]\frac{2+-\sqrt{2^{2}-4(-3)(6) }}{2(-3)}[/tex]

There could also have a simplified version.

I hope this helps.
