Answer: 85%

Step-by-step explanation:

You can use proportions to solve this answer.

17/20=x/100

Solve for X

17(100)/20=x

85=x

Answer:

15% incorrect

Step-by-step explanation:

17/20 = x/100

17 ×5= 85

20×5 = 100

85/100 correct

15/100 incorrect

Answer:

B and D

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The lines have equal slopes

-6/3= -2

And

-8/4 = -2 so both slopes are equal hence the lines are parallel

Answer:

[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]

Step-by-step explanation:

The following expressions are used to transform from polar into rectangular form:

[tex]r = \sqrt{x^{2}+y^{2}}[/tex]

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]

Now, the variables are substituted and equation is finally simplified:

[tex]\sqrt{x^{2}+y^{2}} = 10\cdot \frac{y}{\sqrt{x^{2}+y^{2}} }[/tex]

[tex]x^{2}+y^{2} = 10\cdot y[/tex]

The equivalent equation in rectangular coordinates is:

[tex]x^{2} + y^{2} - 10\cdot y = 0[/tex]

Answer:

X=-2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/2(6x-10)=2x-7

(1/2)(6x)+(1/2)(-10)=2x+-7(Distribute)

3x+-5=2x+-7

3x-5=2x-7

Step 2: Subtract 2x from both sides.

3x-5-2x=2x-7-2x

X-5=-7

Step 3: Add 5 to both sides.

X-5+5=-7+5

X=-2

Hope this helps

Answer:

The radius of the circle with 4 inch diameter is 2 inches

Step-by-step explanation:

This is the formula here:

d = 2r

The radius is solved here:

r = [tex]\frac{d}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 inches

Answer:

b) 14°

Step-by-step explanation:

To solve this, you need to make an equation. since a line is equal to 180°, you can add the two angles together. for example, x+96+5x=180. you would write this because these two angles are on a line, which makes the total sum 180°. now you solve: 6x+96=180. 6x=84. x=14°. :)

Answer:

87.5%

Step-by-step explanation:

First we find the number of students that did wear green which is 120-15=105. Then we need to find what percentage of these students who did wear green so we divide 105 by 120 which is .875. To find this number in percent form, we multiply this number by 100 which gives us 87.5%.

Answer:

87.5%

Answer:

Step-by-step explanation:

It is convenient to compute the areas in terms of grid squares. Then those results can be converted to square meters by multiplying by the area of a grid square: (10 m)² = 100 m².

(a) The area of the school is the product of its side dimensions. The short side is (in terms of grid squares) ...

 W = √(1²+3²) = √10

The long side is ...

  L = √(2²+6²) = √40

Then the area is ...

  A = LW = (√40)(√10) = √400 = 20

The area of the school is 20 grid squares = 2000 m² . . . . . where s = 10 m

__

(b) The area of the museum is given by the formula ...

  A = πr² = π(3)² = 9π grid squares = 2827 m²

The area of the museum is 2827 m².

__

(c) Marci says the museum has a larger area than the school. She is correct.

Marci should win the debate.

Answer: 4,588.4 cubic centimeters.

Step-by-step explanation: 20 centimeters ⋅ 14 centimeters = 280 centimeters = 4588.38 cubic centimeters = 4,588.4 cubic centimeters.

Answer:

Step-by-step explanation:

Givens

We know that the area of a square is

[tex]A=s^{2}[/tex]

Where [tex]s=12 \ ft[/tex], according to the problem.

Replacing this value, we have

[tex]A=(12 \ ft)^{2} =144 \ ft^{2}[/tex]

Therefore, the area of the square roof is 144 square feet.

Answer: the area of the roof is 144 feet squared for each side (up and down), adding to a total of 288 ft^2

Step-by-step explanation:

If the roof is a square with a side lenght L =  12 feet, then we use the fact that the area of a square is equal to the square of the side lenght of the square, this is:

A = L^2  = (12 ft)^2 = 144 ft^2

Now, Mr. wilson uses the equation A = s, this is because the roof has 2 surfaces, one up and one bottom, then the total area is 2 times the value that we find earlier:

2*144 ft^2 = 288 ft^2

Step-by-step explanation:

The correct pairs of angles in the figure which are vertical angles is,

⇒ ∠AKC and ∠TKI

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

To find correct pairs of angles in the figure which are vertical angles.

Now, By definition of vertical opposite angle,

We get;

The correct pairs of angles in the figure which are vertical angles is,

⇒ ∠AKC and ∠TKI

Thus, The correct pairs of angles in the figure which are vertical angles is,

⇒ ∠AKC and ∠TKI

Answer:

C. [tex]F(x) = -x^2 - 3[/tex]

Step-by-step explanation:

The function, F(x), has flipped over the x-axis (as seen) meaning that the function has to have a negative sign in front. The function has also shifted downwards 3 units, meaning that 3 has to have been subtracted from the function.

This makes "C," the correct answer, as it fulfills these requirements.

Answer:

81.7 inches

Circumference = πd. where d is the diameter

this is because cm is the abbreviation of centimeters.

Answer:Surface Area of a Solid

The surface area of a 3-dimensional object is the measure of the total area of all its faces. This means that one way to find the surface area of a solid is to find the area of its net. The surface area of a rectangular prism is the area of the six rectangles that cover it.
