**Answer:**

lets solve it.

Taking LHS:

81^3/2=(81*81*81)/2

531,441/2

**265,720.5**

Now comparing RHS and LHS

265,720.5 & 9

and they are not equal, thus false.

Ali and Jake went on a cross-country

trip. They took a train part of the way,

and took a bus the rest of the way. They

traveled a total of 1100 kilometers,

riding on the train 350 more kilometers

than on the bus.

Let x = kilometers traveled by bus. Let

y = kilometers traveled by train.

**Answer:**

Let x = Kilometers by bus

then x + (x + 350) = 1100

2x = 750

x = 375 by bus

x - 350 + x = 1100

2x = 1450

x = 725 by train

solve for x

solve for x

**Answer:**

121

**Step-by-step explanation:**

Number of sides = n = 7

Sum of all the interior angles = (n -2)*180 = (7-2) *180

= 5 *180

= 900

x + 125 + 119 +117 +145 + 133 + 140 = 900

x + 779 = 900

x = 900 - 779

x = 121

**Answer:**

x = 121°

**Step-by-step explanation:**

The formula to find the** sum of interior angles of a polygon** is:

**180 ( n - 2 )**

Here,

n ⇒ number of sides ⇒ 7

First, let us find the **sum of the interior angles of the polygon.**

180 ( n - 2 )

180 × ( 7 - 2 )

180 × 5

900°.

Accordingly, let us make an expression to find the value of x.

145 + 133 + 140 + 125 + 119 + 117 + x = 900

Let us solve for x now.

779 + x = 900

*Subtract 779 from both sides.*

x = 900 - 779

x =** 121**

What is the slope of a vertical line?

What is the slope of a horizontal line?

Answer:

The slope of a vertical line is undefined. The slope of a horizontal line is 0

Step-by-step explanation:

Slope is rise/run

and the rise of a horizontal line is zero since it neither increases nor decreases; therefore, the slope is zero. while a vertical line has undefined slope since it does not run horizontally because division by zero is an undefined operation.

On a middle school basketball court, there is a large circle painted on the

floor. The diameter of the circle is 12 feet. What is the area of the circle?

Jse 3.14 for a

**Answer:**

113.04 feet²

**Step-by-step explanation:**

Use the **circle area formula, A = **[tex]\pi[/tex]**r²**

Sine the diameter is 12 feet, the **radius is 6 feet**

**Plug in 6 as r into the formula, and 3.14 as pi,** then solve:

A = [tex]\pi[/tex]r²

A = (3.14)(6²)

A = (3.14)(36)

**A = 113.04**

So, the area of the circle is approximately** 113.04 feet²**

**Answer:**

113.04 feet²

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place

**Step-by-step explanation:**

*I think you have forgotten to attach the question. *

*Anyways....*

In order to find the area of a circle use the formula:

**π**[tex]r^{2}[/tex]** ** Where r is the radius

For example the radius is 3cm. The area of the circle will be:

π × [tex]3^{2}[/tex]

Since you have taken pi as 3.142...

3.142 × [tex]3^{2}[/tex]

3.142 × 9

= 28.278

In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.

= **28.3 **[tex]cm^{2}[/tex]

3) The cost of a movie ticket and a candy bar is $5. The cost of 2 tickets

and a candy bar is $8.75. How much is a candy bar? *

Answer:

$1.25

Step-by-step explanation:

Given data

let the movie ticket be x and the candy bar be y

x+y= 5-------------1

also

2x+y= 8.75--------2

solve 1 and 2

x+y= 5

2x+y= 8.75

from 1

x= 5-y

put this inplace of x in 2

2(5-y)+y=8.75

10-2y+y= 8.75

10-y= 8.75

10-8.75=y

y= 1.25

Hence candy bar is $1.25

Help please I’m confused

3y= 21

I think 3y would be 21 because in the equation, 5y+13=48, y= 7. So if we know that y is 7 that’ll mean we’ll use 7 to interpret y for 3y.

Use the Distance Formula to find the distance between each pair of points. Round to the nearest tenth if necessary.

5. P(1, 1), Q(–1, –1)

6. E(1/2,4 1/4),F(5,-1/2)

**Given:**

The pair of points.

5. P(1, 1), Q(–1, –1)

6. [tex]E\left(\dfrac{1}{2},4\dfrac{1}{4}\right), F\left(5,-\dfrac{1}{2}\right)[/tex]

**To find:**

The distance between the pair of points.

**Solution:**

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

5.

The distance between the pair of points P(1, 1) and Q(–1, –1) is:

[tex]PQ=\sqrt{(-1-1)^2+(-1-1)^2}[/tex]

[tex]PQ=\sqrt{(-2)^2+(-2)^2}[/tex]

[tex]PQ=\sqrt{4+4}[/tex]

[tex]PQ=\sqrt{8}[/tex]

[tex]PQ=2\sqrt{2}[/tex]

**Therefore, the distance between P and Q is [tex]2\sqrt{2}[/tex].**

6.

The distance between the pair of point [tex]E\left(\dfrac{1}{2},4\dfrac{1}{4}\right), F\left(5,-\dfrac{1}{2}\right)[/tex] is:

[tex]EF=\sqrt{\left(5-\dfrac{1}{2}\right)^2+\left(-\dfrac{1}{2}-4\dfrac{1}{4}\right)^2}[/tex]

[tex]EF=\sqrt{\left(\dfrac{10-1}{2}\right)^2+\left(-\dfrac{1}{2}-\dfrac{17}{4}\right)^2}[/tex]

[tex]EF=\sqrt{\left(\dfrac{9}{2}\right)^2+\left(\dfrac{-2-17}{4}\right)^2}[/tex]

[tex]EF=\sqrt{\dfrac{81}{4}+\left(\dfrac{-19}{4}\right)^2}[/tex]

On further simplification, we get

[tex]EF=\sqrt{\dfrac{81}{4}+\dfrac{361}{16}}[/tex]

[tex]EF=\sqrt{\dfrac{324+361}{16}}[/tex]

[tex]EF=\sqrt{\dfrac{685}{16}}[/tex]

[tex]EF=\sqrt{42.8125 }[/tex]

[tex]EF\approx 6.5[/tex]

**Therefore, the distance between E and F is 6.5 units.**

**Answer:**

x = 65

**Step-by-step explanation:**

Triangle interior angle sum is 180 degrees.

2x + 25 + 25 = 180

2x = 130

x = 65

Answer:

65

Step-by-step explanation:

OK so we know that the bottom line shows a 180 degrees angle

so 180-25+25 = 180-50 = 130

Now divide 130 by 2 and you should get 65.
