Step-by-step explanation:

Answer:

Let the scores on the first two test be x

Let score for third test be 14 exceeds second( or first) = x + 14

Total = 233

x + x + (x + 14) = 233

3x + 14 = 233

3x = 219

x = 73

Score of the third test = x + 14 = 73 + 14 = 87

Therefore, the scores are 73, 73, 87

Answer: (1, 3)

Step-by-step explanation: The endpoint of PQ are respectively (-2, -2), and (4, 8). Add  them  up and divide by 2 to find midpoint≈ 1,3

Answer:

75ft^2

Step-by-step explanation:

A = pi*r^2

The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.

Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.

3*(5)^2 = A

Simplify

3*25

Multiply

Area=75ft^2

Answer:

1/6

Step-by-step explanation:

Answer:

Volume, V = 75.41 cubic inches.

Step-by-step explanation:

Given the following data;

Radius, r = 3 inches

Height = 8

To find the volume of the right circular cylinder;

Mathematically, the volume of a right circular cylinder is given by the formula;

V = πr²h

Where;

Substituting into the formula, we have;

Volume, V = 3.142 * 3 * 8

Volume, V = 3.142 * 24

Volume, V = 75.41 cubic inches.

Answer:

The interval is [4,7]

Step-by-step explanation:

The rate of change is given by

f(x2) - f(x1)

-------------------

x2 -x1

We want the rate of change to be 56

f(x2) - f(x1)

-------------------  = 56

x2 -x1

We also know that the x2 is 7  so f(x2) = 192

192 - f(x1)

-------------------  = 56

7 -x1

192 - f(x1) = 56( 7 -x1)

192 - f(x1) = 392 -56x1

Now we need to pick points from the table and see where it is true

(6,96)

192 - 96 = 392 -56*6

96=56  False

( 5,28)

192 - 28 = 392 -56*5

164=112  False

(4,24)

192 - 24 = 392 -56*4

168=168  True

The interval is [4,7]

D) SSS congruence theorem

Step-by-step explanation:

Edge 2021

Answer:

B,48.2

Step-by-step explanation:

To solve this we need to use SOH, CAH, TOA

we have the adjacent and hypotonouse so it's easiest to use CAH

let theta (angle) = x

cos(x)=4/6

to cancel the cos mulitply both sides by cos^-1 (2nd --> cos)

x=48.1896851

which rounds to 48.2

Answer:

4x.

Step-by-step explanation:

we will begin by solving the problems.

after we have done that we will find the perimeter.

remember: The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

so the equation is 1x + 1x + 1x + 1x

Answer:

z=16

Step-by-step explanation:

I was finding the variable by the way

Answer:

[tex] {3y}^{3} - 12y \\ = 3y( {y}^{2} - 4) \\ = 3y( {y}^{2} - {2}^{2} ) \\ = 3y(y - 2)(y + 2) \\ = 3y(y + 2)(y - 2)[/tex]

a^2-b^2=(a+b)(a-b)

a=y b=2

3y(y+2)(y-2)

Answer:

D. None of these figures.

None of the figures above highlight two-dimensional objects.

Cube A, Cube B, and Cube C are all three-dimensional objects because they have length, width, and height.

A two-dimensional object would have only length and width, without any thickness or height. Examples of two-dimensional objects include shapes such as circles, squares, and triangles, as well as flat surfaces like paper or computer screens.

Answer:

um could you transkate to english so i can answer your question?

Step-by-step explanation:

Answer:

T= (-4 ,2)

U= (2 ,4)

V= (3 ,1)

W= (-3, -1)

1 . LENGTH OF EACH SIDES

 [tex]length \ of \ sides =\sqrt{(x_{2} -x_{1} )^2+(y_{2} -y_{1})^2}[/tex]

[tex]length \ of \ TU = \sqrt{(2--4 )^2+(4-2)^2} = \sqrt{40}[/tex]

[tex]Length \ of \ UV =\sqrt{(3-2 )^2+(1-4)^2} = \sqrt{10}[/tex]

[tex]Length \ of \ VW =\sqrt{(-3-3)^2+(-1-1)^2} = \sqrt{40}[/tex]

[tex]length \ of \ TW =\sqrt{(-3--4 )^2+(-1-2)^2} =\sqrt{10}[/tex]

2. SLOPE OF CONSECUTIVE SIDES

[tex]Slope \ of \ the \ line \ passing \ through \ (x_{1}, y_{1} ) \ and \ (x_{2}, y_{2}) = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]Slope \ of \ TU = \frac{4-2}{2--4} = \frac{2}{6} =\frac{1}{3}[/tex]

[tex]Slope \ of \ UV = \frac{1-4}{3-2} = -3[/tex]

[tex]Slope \ of \ VW = \frac{-1-1}{-3-3} = \frac{-2}{-6} =\frac{1}{3}[/tex]

[tex]Slope \ of \ TW = \frac{-1-2}{-3--4} = -3[/tex]

[tex]Slope \ of \ lines \ parallel \ to \ each \ other = m_{1}\cdot m_{2} = 1\\Slope\ of \ lines\ perpendicular \ to \ each \ other =m_{1}\cdot m_{2} = -1\\[/tex]

[tex]Slope \ of \ TU * UV = \frac{1}{3}*-3 = -1\\\\Slope \ of \ UV *VW = -3 *\frac{1}{3}= -1\\\\ Slope \ of \ VW * TW = \frac{1}{3}*-3 = -1\\\\Slope \ of \ TW * TU = -3 *\frac{1}{3}= -1\\\\[/tex]

Therefore the consecutive sides are perpendicular to each other.

3. TYPE OF PARALLELOGRAM

The opposite sides are of same length.  The consecutive sides are perpendicular to each other. So the parallelogram is a RECTANGLE.

the expression equivalent to that is D

Answer:

if he can afford 18 dollars for guest you just divide 18 by 3 and you get 6 so isacc can invite 6 people at most to his birthday party

Step-by-step explanation:

Answer:

I think the answer is D (hope its right)

Step-by-step explanation:

Answer:

We know that points A, B, C, and D are on a line.

Point A is between B and C

Point  D is to the left of C.

Now we want to find the order of these points using the given information.

Then the order could be:

First, we write D at the left of C

Then we remember that A is between B and C

D C A B

Now, D could be to the left of C, but not directly at the left of C, so we can also have the order:

D B A C

Where D is at the left of C but not directly at the left.

Answer:
