Step-by-step explanation:

8 yards / 3 equal pieces = 8/3 yards for each piece or 2 1/3.

Answer: 2 2/3 yards

Step-by-step explanation:

The ribbon is 8 yards long

it is cut in 3 equal pieces so

8 yards divided by 3 yards = 2 2/3 yards

Answer:

Pretty sure it's 2 strides

Step-by-step explanation:

To get from 7 to 5 you minus by 2, and look how many spaces there are. There are 2

Two lines y = -x + 3 and y = 2x - 5 are graphed to find their intersection, which gives the x and y values that satisfy both equations.

To find x and y values that satisfy both equations y = -x + 3 and y = 2x - 5, we need to graph these equations and look for their point of intersection.

The intersection represents the x and y values that make both original equations true simultaneously. Use the graph to identify the coordinates of this point for the exact solution.

Out of the choices provided, only [tex]$(-3,5)$[/tex] lies on the intersection of the two lines. Thus the answer is a. [tex]$(-3,5)$[/tex].

Here's a step-by-step solution to find the x and y values that satisfy both equations:

1. Graph the Equations:

    Take the first equation, y = -2/3x + 3. This equation is in slope-intercept form (y = mx + b), where m (slope) is -2/3 and b (y-intercept) is 3.

     -   Plot the y-intercept (3) on the y-axis.

      -  Since the slope is -2/3, remember "rise over run." So in this case for every 2 positions you move down (because it's negative), you move  3 positions to the right. Plot another point based on this movement.

       - Connect these two points with a straight line.

  -  Repeat the process for the second equation, y = 2x - 5. This equation is also in slope-intercept form with m (slope) as 2 and b (y-intercept) as -5.

       - Plot the y-intercept (-5) on the y-axis.

       - The slope is 2, so for every 2 positions you move up, you move 1 position to the right. Plot another point based on this movement.

       - Connect these two points with a straight line.

2. Find the Intersection Point:

   - Observe the graph. The point where the two lines intersect represents the solution where both equations are true simultaneously.

   - In this case, the lines intersect at the point (-3, 5).

Verification:

   - You can substitute x = -3 and y = 5 in both the original equations and see if they hold true.

      - For y = -2/3x + 3, substituting x = -3 gives you y = (-(2/3) [tex]\times[/tex] (-3)) + 3 = 2 + 3 = 5 (which is true).

      - For y = 2x - 5, substituting x = -3 gives you y = (2 [tex]\times[/tex] -3) - 5 = -6 - 5 = -11 (which is not true).

Therefore, the solution (x, y) that makes both equations true is (-3, 5). This is the point where the two lines intersect on the graph.

The graph is provided below.

Answer: C= 50.2652

Step-by-step explanation:

The circumference of a circle with an area of 201.06 square inches is approximately 50.24 inches, after calculating the radius from the area and applying it to the circumference formula.

To find the circumference of a circle when given the area, you'll want to perform a series of mathematical steps. The area of a circle is given by the formula A = πr², and the circumference is given by C = 2πr. You can rearrange the area formula to solve for the radius, r, and then substitute that into the circumference formula.

First, solve for the radius:
A = πr² → r = √(A/π) → r = √(201.06/π).

Once you have r, plug it into the circumference formula:

C = 2πr.

Using a calculator, you'll find the following values:

The circumference of a circle with an area of 201.06 square inches is approximately 50.24 inches.

Step-by-step explanation:

Given : BC is parallel to DE

To Find : What is the length of CE?

Solution :

AB = 3

BD = 2

AC = 4

Since BC || DE

So, [tex]\frac{AB}{BD}=\frac{AC}{CE}[/tex]

[tex]\frac{3}{2}=\frac{4}{CE}[/tex]

[tex]CE=\frac{4 \times 2}{3}[/tex]

[tex]CE=\frac{8}{3}[/tex]

[tex]CE=2\frac{2}{3}[/tex]

Hence the length of CE is [tex]2\frac{2}{3}[/tex]

Answer:

x and see others below

Step-by-step explanation:

To find the equivalent expression, multiply the terms using exponent rules.

Exponent rules state to add the exponent of same bases being multiplied.

[tex]x^{\frac{1}{2}} *x^{\frac{1}{2}} =x^{\frac{1+1}{2}} =x^{\frac{2}{2}} = x^1 = x[/tex]

Each of the parts of the expression are equivalent. The simplified equivalent expression is x.

∴(108+27) cubic feet = 135 cubic feet of concrete are required.

The dimension of lower step is 6 ft× 3 ft× 1.5 ft

and the dimension of upper step is 6 ft ×(9-3)ft × (1.5+1.5)ft = 6 ft × 6 ft ×3 ft

Therefore concrete are required to make lower step = (6×3×1.5) cubic feet

                                                                                      = 27 cubic feet

and concrete are required to make upper step = (6×6×3) cubic feet

                                                                              =108 cubic feet

∴(108+27) cubic feet = 135 cubic feet of concrete are required.

Answer:

option C. [tex]KL=2*JL[/tex]

option D. [tex]JK=\frac{\sqrt{3}}{2}*KL[/tex]

option F. [tex]JK=\sqrt{3}*JL[/tex]

Step-by-step explanation:

step 1

we know that

In the right triangle JKL

[tex]sin(30\°)=\frac{JL}{KL}[/tex]

[tex]sin(30\°)=\frac{1}{2}[/tex]

so

[tex]\frac{1}{2}=\frac{JL}{KL}[/tex]

[tex]KL=2*JL[/tex]

step 2

[tex]cos(30\°)=\frac{JK}{KL}[/tex]

[tex]cos(30\°)=\frac{\sqrt{3}}{2}[/tex]

so

[tex]\frac{\sqrt{3}}{2}=\frac{JK}{KL}[/tex]

[tex]JK=\frac{\sqrt{3}}{2}*KL[/tex]

step 3

[tex]tan(30\°)=\frac{JL}{JK}[/tex]

[tex]tan(30\°)=\frac{1}{\sqrt{3}}[/tex]

[tex]\frac{1}{\sqrt{3}}=\frac{JL}{JK}[/tex]

[tex]JK=\sqrt{3}*JL[/tex]

Step-by-step explanation:

Use the distributive formula to solve for x:

a(b + c) = ab + ac

-3(4x - 2) = 21 - 4(1 + 4x)

1. Use distributive property:

-12x + 6 = 21 - 4 - 16x

2. Simplify:

-12x + 6 = 17 - 16x

3. Add 16x to both sides

-12x + 16x + 6 = 17 - 16x + 16x

4. Simplify:

4x + 6 = 17

5. Subtract 6 from both sides

4x + 6 - 6 = 17 - 6

6. Simplify

4x = 11

7. Now, divide both sides by 4

4x/4 = 11/4

Answer:

x = 2.75

Explanation:

Solve for x:

Use distributive property.

−3(4x − 2) = 21 − 4(1 + 4x)  

Combine like terms.

-12x + 6 = 21 - 4 - 16x

Add -12x on both sides.

-12x + 6 = 17 - 16x

+ 12x             + 12x

Subtract 17 on both sides.

6 = 17 - 4x

-17  -17

Divide -4 on each side to get x alone.

-11 = -4x

----   -----

-4      -4

And you get your solution to x.

2.75 = x

Check:

Substitute 2.75 to x.

−3(4(2.75) − 2) = 21 − 4(1 + 4(2.75))  

Multiply 2.75 by 4.

-3(11 - 2) = 21 - 4(1 + 11)

Distribute.

-33 + 6 = 21 - 4 - 44

Subtract 21 by 4.

-33 + 6 = 17 - 44

Subtract.

So, Sam only asked 20 people in his entire middle school. That is a very small fraction of the amount of kids attending that school. He cannot say that video games is 75% of the entire school's favorite weekend activity if he only asked 20 people. To get a better, more valid result, he should ask around 100+ kids.

Step-by-step explanation:

The simplified expression is x + 46.

To simplify the expression, let's distribute and simplify each term:

4(-8x + 5) - (-33x - 26)

First, distribute 4 into -8x + 5:

= -32x + 20

Then, distribute -1 into -33x - 26:

= -32x + 20 + 33x + 26

Now, combine like terms:

= (-32x + 33x) + (20 + 26)

= 1x + 46

= x + 46

So, the simplified expression is x + 46.

The difference between the square of 80 and the square of 20 is 6000.

The student's question appears to ask for the difference between the squares of two numbers, specifically square 20 and square 80.

To find this difference, each number must be squared and then the smaller result subtracted from the larger one.

Squaring a number means multiplying the number by itself, so square 20 (which is 20²) equals 400 and square 80 (which is 80²) equals 6400.

Next, we find the difference by subtracting the smaller square from the larger one:

6400 (square 80) - 400 (square 20) = 6000

This calculation reveals that the difference between the square of 80 and the square of 20 is 6000.

the slope is 2

Associative property does not work for Subtraction and Division.

The associative property states that after grouping the expressions in different ways the outcome will not change.

(a + b) + c = a +(b + c)

So associative property is applicable for addition.

( a X b) X c = a X ( b X c) = abc

So associative property is applicable for multiplication

(a ÷ b) ÷ c ≠ a ÷ (b ÷ c)

So, the associative property is not applicable for  Division

(a-b) - c ≠ a - (b -c)

- The ground is at 0 feet.

- The initial posititions of both elevators were at 0 feet (because both moved from the ground level).

Therefore:

- If the final position of Elevator 1 is at +17 feet (positive) means that it moved 17 feet above the ground level.

- If the final position of Elevator 2 is at -22 feet (observe the negative sign) means that it moved 22 feet below the ground level.
