A(-8,5)

B(-16, 10)

C (2,-2)

D (4,-4)

Choose

The answer is A (-8,5)

**Answer:**

*A(-8,5)*

**Step-by-step explanation:**

Given two points (-6, 3), and (-10, 7). The midpoint is calculated by averaging the x, and y values of two coordinates. As (-10, 7) is the the first point (x1, y1), and (-6, 3) is the second point (x2, y2).

[tex]midpoint \: of \: (x_{1},y_{1}), \: and \: (x_{2},y_{2}) \\ = (\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})[/tex]

[tex] midpoint \: of \: (-6,3), \: and \: (-10,7) = (\frac{-10 + -6}{2}, \frac{7 + 3}{2}) \: = (\frac{-16}{2}, \frac{10}{2}) \: = (-8,5)[/tex]

Add 3x to each side

2-3x+3x= -x+3x-8

2 = 2x-8

Add 8 to each side

2+8 = 2x-8+8

10 =2x

1/3 minus 1/6 equals to???

**Answer:**

1/6

**Step-by-step explanation:**

In order to add or subtract fractions you have to have the same denominator for both factions. you do this through finding the Lowest Common Denominator (LCD) In this case it's six because both 3 and 6 (the denominators) can go into 6. So turn 1/3 into a fraction with 6 as the denominator through multiplying both the top and bottom of the fraction by 2

1/3 * 2/2 = 1*2/3*2 = 2/6

Then you can straightforwardly subtract

2/6 - 1/6 = 1/6

Determine the height of the triangle if the area is 24 square inches and the base is 12 inches.

**Answer:**

4

**Step-by-step explanation:**

We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4

Answer: 6 inches

Step 1: Subtract 12 because 12 iches is the base.

24 - 12 = 2

Step 2: Divide 12 by 2 because triangles have two equal sides.

12 ÷ 2 = 6

Answer = 6

A carpenter cuts a circle out of a piece of wood. The radius of the circle is

about 23 inches. The carpenter cuts the circle into two semicircles. What is

the area of one semicircle to the nearest hundredth? Use 3.14 for

**Answer:**

830.53 in²

**Step-by-step explanation:**

To find the area of one semicircle,** find the area of the full circle and divide it by 2:**

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

**Plug in 3.14 as pi, and plug in the radius:**

A = [tex]\pi[/tex]r²

A = 3.14(23²)

A = 1661.06

Divide this by 2:

1661.06 / 2

**= 830.53**

So, the area of one semicircle is **830.53 in²**

**Answer:**

850.53 in² is the answer

In 1999, Marks & Spencer, a British department store, created the biggest sandwich ever made. The tuna and cucumber sandwich was in the form of a triangular prism. Suppose each slice of bread was 8 inches thick. Find each measure to the nearest tenth. a. The surface area in square feet of the sandwich when filled b. The volume of filling in cubic feet to the nearest tenth

**Answer:**

A) 19.2 ft^2

B) 28.9 ft^3

**Step-by-step explanation:**

Thickness = 8 inches

Assuming the triangular prism is made up of an equilateral triangle hence all sides are equal

lets assume the side = 10 inches

lets assume the thickness as the height of the prism = 8 inches

Assume length of the rectangle(l) = 5 feet

A) The surface area of the sandwich triangular prism

total surface area = bh + 2ls + lb

= 10*8 + 2(5*10) + ( 5 * 10 )

= 80 + 100 + 50 = 230 inches =** 19.2 ft^2**

B ) The volume of filing in cubic feet to the nearest tenth

V = [tex]\frac{1}{4} h \sqrt{-a^4 +2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}[/tex] ------- 1

where : a = b = c = 10 inches

h = 8 inches

input the given values into the equation 1 above

V= 346.41 inches ^3 = **28.9 ft^3**

Rachel earned $ 34 $34dollar sign, 34 in 4 44 hours at her job today. She wants to know how much she could earn ( e ) (e)left parenthesis, e, right parenthesis tomorrow if she works 10 1010 hours at the same hourly rate. How much will Rachel earn in 10 1010 hours? $

**Answer:**

Rachel earn $85 in 10 hours.

**Step-by-step explanation:**

Rachel earned $34 in 4 hours at her job today. It means we can find his earning in 1 hour.

1 hour = $(34/4)

**= $8.5**

He earns $8.5 in an hour.

To find his earning in 10 hours, multiply $8.5 by 10. So,

Earning = $8.5 × 10

**= $85**

**Hence, Rachel earn $85 in 10 hours.**

The power generated by an electrical circuit (in watts) as a function of its current x xx (in amperes) is modeled by P ( x ) = − 15 x ( x − 8 ) P(x)=−15x(x−8)P, left parenthesis, x, right parenthesis, equals, minus, 15, x, left parenthesis, x, minus, 8, right parenthesis What current will produce the maximum power?

**Given:**

The power generated by an electrical circuit (in watts) as a function of its current x (in amperes) is modeled by

[tex]P(x)=-15x(x-8)[/tex]

**To find:**

The current which will produce the maximum power.

**Solution:**

We have,

[tex]P(x)=-15x(x-8)[/tex]

[tex]P(x)=-15x^2+120x[/tex]

Differentiate with respect to x.

[tex]P'(x)=-15(2x)+120(1)[/tex]

[tex]P'(x)=-30x+120[/tex] ...(i)

To find the extreme point equate P'(x)=0.

[tex]-30x+120=0[/tex]

[tex]-30x=-120[/tex]

Divide both sides by -30.

[tex]x=4[/tex]

Differentiate (i) with respect to x.

[tex]P'(x)=-30(1)+(0)[/tex]

[tex]P'(x)=-30<0[/tex] (Maximum)

It means, the given function is maximum at x=4.

**Therefore, the current of 4 amperes will produce the maximum power.**

**Answer:**

its 4 amperes

Which of the following is both a perfect square and a perfect cube?

64

16

81

1,000

I know the answer is 64, but how? Can someone please explain me to me how to work this out?

Well the square root of 64 is 8, and the cube root of 64 is 4. They’re perfect whole numbers. We know 4 x 4 = 16 is a square from the fact above, and also because of what a square means. But we can go one step further. 4 x 16 = 64 is the product of two squares, so it is also a square. But you can also write it as 64 = 4 x 4 x 4, making it a cube.

The altitude of a helicopter increase is 1000 feet every four minutes. What is the unit rate of change (feet per minute) of the altitude?

**Answer:**

3g -6 = 8

3g= 8+6

3g= 14

[tex] \frac{3g}{3} = \frac{14}{3} [/tex]

g=4⅔

hope this helps

**Step-by-step explanation:**

3(g - 2) = 8

3(g - 2) = 8

+ 2 +2

3g = 8

3÷3= 0 8÷3 = 4.6

so your answer will be g= 4.6 (5 if you round it up) or if you need it in fraction form it will be 4 and 2/3

How are lines KL and MN related?

O The lines intersect at point K.

O The lines are parallel.

O The lines are perpendicular.

O The lines do not have slopes,

The lines are perpendicular

The lines KL and MN** perpendicular **to each other.

In mathematics, the **slope **or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, **slope** is calculated as "rise over run" (change in y divided by change in x).

here, we have,

If a line passes through two points, then the **slope** of the line is

m = y2-y1/x2-x1

From the given graph it is clear that coordinates of points on line KL are K(-8,2) and L(6,2).

The **slope** of line KL is

m = 0

The **slope **of line KL is 0, it means it is a horizontal line.

From the given graph it is clear that coordinates of points on line MN are M(-4,8) and N(-4,-6).

The** slope **of line MN is

m = 1/0

The slope of line MN is 1/0 or undefined, it means it is a vertical line.

We know that vertical and horizontal lines are **perpendicular **to each other.

Therefore the lines KL and MN **perpendicular** to each other.
