Answer:

Tanisha wrote an equation that is the same as Mrs. McAlister's equation.

9t = 8

Step-by-step explanation:

Mrs. McAlister wrote an equation on the board is:

10t-4t+3t=8

Now we simplify this

In order to simplify the left side, we combine like terms.

Here 10t, -4t, & 3t are like terms

So, 10t - 4t + 3t is equivalent to 9t

Thus,

9t = 8

This equation is written by the Tanisha.

That's the final answer.

I hope it helps you.

Answer:

Tanisha

Step-by-step explanation:

10t - 4t + 3t = 8    (given)

= 10t - 4t + 3t  = 8

= 9t = 8

This is what Tanisha wrote (9t = 8)

The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

          Cylinder has a 5 centimeters height

          Diameter of the cylinder is 1.5 centimeters

Step:1

          Formula for the surface area of cylinder is,

                     [tex]A=2\pi r h + 2\pi r^{2}[/tex]......................................(1)

          Where,

                   h - Height of cylinder

                   r - Radius of cylinder

        From the values of h and r,

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

                      = [tex]\frac{1.5}{2}[/tex]

                   r  = 0.75 cm

       From the formula,

                      = ( 2 × [tex]\pi[/tex] × 0.75 × 5 ) + ( 2 × [tex]\pi[/tex] × [tex]0.75^{2}[/tex] )

                      = ( 7.5 [tex]\pi[/tex] ) + ( 1.125 [tex]\pi[/tex] )

                  A = 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex]

Result:

        The surface area of cylinder is 8.625[tex]\pi[/tex] [tex]cm^{2}[/tex], if the cylinder has 5 centimeters high and 1.5 cm of diameter.

The surface area of a cylinder is 8.625π cm². Thus, the correct answer is B.

First, calculate the radius of the cylinder, which is half of the diameter:

r = 1.5 cm / 2

   = 0.75 cm

Next, find the area of the two circular bases of the cylinder using the formula for the area of a circle, A = πr²:

Area of one base = π(0.75 cm)²

                              = 0.5625π cm²

Total area of the two bases = 2 × 0.5625π cm²

                                              = 1.125π cm²

Then, calculate the lateral surface area using the formula for the circumference of a circle (C = 2πr) multiplied by the height (h):

Lateral surface area = 2π(0.75 cm)(5 cm)

                                  = 7.5π cm²

Finally, add the areas of the two bases and the lateral surface area to find the total surface area:

Total surface area = 1.125π cm² + 7.5π cm²

                              = 8.625π cm²

The correct answer is B. 8.625π cm².

Answer:

See below for answers

Step-by-step explanation:

Part 1:

Angle 1 is a supplementary angle, so it must be 180-50=130 degrees because supplementary angles add up to 180 degrees.

Angle 2 is a vertical angle, therefore it must be 50 degrees as well because vertical angles are congruent.

Angle 3 is vertical to angle 1, so it is 130 degrees since vertical angles are congruent.

Part 2:

x and 2x+21 are supplementary angles, so we can make an equation:

x+2x+21=180

3x+21=180

3x=159

x=53

So x=53

Answer:

1 = 130

2 = 50

3 = 130

4 = x = 53

Step-by-step explanation:

angle 2 is congruent to 50 degrees

1 and 3 are congruent

1 and 2 are supplementary

3x+21 = 180

3x = 159

x = 53

The temperature at the top of the mountain is -15.2°C.

The solution to the problem:

Given:

The temperature at the base of the mountain is -4.4°C.

The temperature at the top of the mountain is 10.8°C less than the temperature at the base of the mountain.

Objective:

Determine the temperature at the top of the mountain.

Solution:

Let x be the temperature at the top of the mountain. We know that the temperature at the top of the mountain is 10.8°C less than the temperature at the base of the mountain, so we can write the following equation:

x = -4.4 - 10.8

Simplifying the right side of the equation, we get:

x = -15.2°C

A. There are 8 fluid oz in 1 cup.

Multiply 8 with 6:

6 cups x 8 = 48 fl oz.

44 fl oz < 48 fl oz ∴ A. is false.

B. There are ~6.67 pints in 1 gallon.

Multiply 6 gallon with 6.67:

6 gallon x 6.67 = ~40.02 pint.

47 pint > 40.02 pint ∴ B. is false.

C. There is 4 quarts in 1 gallon.

Multiply 6 gallons with 4:

6 gallon x 4 = 24 quarts.

24 quarts < 25 quarts ∴ C. is true.

D. There is 4 cups in 1 quarts.

Multiply 7 with 4 and add 4:

7 quarts x 4 = 28 + 4 = 32

32 cups < 34 cups ∴ D. is false.

[tex]1/8[/tex]

Answer:  [tex]1/8[/tex]

Answer: the answer is 1/8

Step-by-step explanation:

Ok use a Calculator to help you.

The solution to the system of equations is x = 4 and y = 2.

Let's solve the system of equations:

4x - 12y = -8

-3x + 12y = 12

We can solve this system using the method of addition or elimination. Adding the two equations eliminates y:

(4x - 12y) + (-3x + 12y) = -8 + 12

Simplifying:

4x - 3x = 4

x = 4

Now that we have found x = 4, we can substitute this value back into one of the original equations to solve for y. Let's use the second equation:

-3x + 12y = 12

-3(4) + 12y = 12

-12 + 12y = 12

12y = 12 + 12

12y = 24

y = 24 / 12

y = 2

Quadrant one: positive x and positive y. (5,6)

Quadrant two: negative x and positive y. (-5,6)

Quadrant three: negative x and negative y. (-5,-6)

Quadrant four: positive x and negative y. (5,-6)

the y-axis goes up and down so im guessing the x coordinates will be 0 and the y will be whatever you want it to be. the same goes for the x-axis excepted switched around.

Apologies if I got any of these wrong, and please comment if you are confused so I can explain more.

1.) First quadrant: x > 0, y > 0.

2.) Second quadrant: x < 0, y > 0.

3.) Third quadrant: x < 0, y < 0.

4.) Fourth quadrant: x > 0, y < 0.

5.) On y-axis: x = 0, y ≠ 0.

6.) On x-axis: x ≠ 0, y = 0.

1.) Points in the First Quadrant: In the first quadrant, both x and y coordinates are positive. Therefore, the coordinates of points A and B might be of the form (x, y) where x > 0 and y > 0. For instance, point A might be (3, 4) and point B might be (5, 7).

2.) Points in the Second Quadrant: In the second quadrant, x coordinates are negative and y coordinates are positive. Thus, the coordinates of points D and E might be of the form (-x, y) where x > 0 and y > 0. For example, point D might be (-2, 3) and point E might be (-6, 8).

3.) Points in the Third Quadrant: In the third quadrant, both x and y coordinates are negative. Therefore, the coordinates of points G and H might be of the form (-x, -y) where x > 0 and y > 0. For instance, point G might be (-4, -5) and point H might be (-7, -9).

4.) Points in the Fourth Quadrant: In the fourth quadrant, x coordinates are positive and y coordinates are negative. Thus, the coordinates of points J and K might be of the form (x, -y) where x > 0 and y > 0. For example, point J might be (3, -2) and point K might be (8, -5).

5.) Points on the Y-Axis: Points on the y-axis have x coordinates equal to 0, and their y coordinates can be positive or negative. Thus, the coordinates of points M and N might be of the form (0, y). For instance, point M might be (0, 4) and point N might be (0, -7).

6.) Points on the X-Axis: Points on the x-axis have y coordinates equal to 0, and their x coordinates can be positive or negative. Thus, the coordinates of points Q and R might be of the form (x, 0). For example, point Q might be (5, 0) and point R might be (-3, 0).
