Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it

Answers

Answer 1

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Answer 2

Answer:

0.98

Step-by-step explanation:

3n-6=-8(6+5n)

3n-6=-48-40n

3n=-48-40n+6

40n+3n=-42

43n=-42

n=0.98 (I rounded it)

Combine like terms. Your answer should contain decimals. 0.5(x4 − 9) + 15 = Please in 10 mins please

Answers

Answer:

x ≈ ±2.1407

Step-by-step explanation:

0.5(x⁴ - 9) + 15 = 0

Distribute the 0.5 across the parentheses.

0.5x⁴ - 4.5 + 15 = 0

Combine the constants.

0.5x⁴ + 10.5 = 0

Subtract 10.5 from both sides.

0.5x⁴ = -10.5

Divide both sides by 0.5.

x⁴ = 21

Take the fourth root of 21.

⁴√21 ≈ ±2.1407

x ≈ ±2.1407

Step-by-step explanation:

Given:

Length of rope (Hypotenuse) = 36 ft

Base = 17 ft

Find:

Height of pole (Perpendicular)

Computation:

Perpendicular = √Hypotenuse² - Base²

Which equation best represents the graph shown above?

Answers

Answer:

B

Step-by-step explanation:

Choose an x point. Then plug it in and see if you get the correct y.

For example, I chose an x point of -1. When x = -1, you can see that y = 4.

Plug it in to the equations, and you find that B is correct.

y (4) = [tex]x^{2}[/tex] (-1 x -1) - 2x ( 2 times -1) + 1

4 = 1 - (-2) + 1

4 = 1 + 2 + 1

4 = 4

Answer:

x=6.36

Step-by-step explanation:

In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:

[tex]9=x\sqrt{2}[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex]

[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]

Divide both sides by 2

[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]

[tex]x=6.36[/tex] (this answer is approximate)

Therefore, x is equal to 6.36.

Okey.but where is your question
The answer for the first one is y=-1/2x+4, you can find this by graphing it and finding the slope by using rise over run and once you have the slope you can plot the rest of the points to find the y-int. For the other one it is y=-3x+8. I also really suggest using the Desmos graphing calculator online, you got plot the points and then once you have an answer you can check it by plugging in the equation.

What is the area of this triangle?
A=bh2


a-54 cm²

b-90 cm²

c-108 m²

d-216 m²

Answers

Answer:

a

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 9 and h = 12 , then

A = [tex]\frac{1}{2}[/tex] × 9 × 12 = [tex]\frac{1}{2}[/tex] × 108 = 54 cm²

It’s a because 12x9=108 then divide it by 2 and you have 54

Answers

Answer:

65

Step-by-step explanation:

the square means 90 add that to 25 and subtract from 180

Answer:

x =  65

Step-by-step explanation:

The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.

All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.

90 + x + 25 = 180

Subtract 90 and 25 from both sides.

90 + x + 25 - 90 - 25 = 180 - 90 - 25

x =  65

Find the standard deviation of T.

OT = 15 seconds

Or = 75 seconds

or 15 seconds

or = v75 seconds

Answers

Answer:

d

Step-by-step explanation:

The standard deviation of T is equivalent to 5.

What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.Mathematically, we can write -

       [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]

Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.

We can write that -

5 = √∑(x{i} - 10)²/√3

√∑(x{i} - 10)² = 5√3

(√∑(x{i} - 10)²)² = (5√3)²

∑(x{i} - 10)² = 25 x 3

∑(x{i} - 10)² = 75

Now, we can write that -

σ = √(75/3)

σ = √25

σ = 5

Therefore, the standard deviation of T is equivalent to 5.
