The Answer is:

Answer:

1. n = 0.2

2. n ≈ 1.396577191 or n ≈ -1.521577191

Step-by-step explanation:

Q1:

[tex]5(n-2)+9 = 0[/tex]

[tex]5n-10 = -9[/tex]

[tex]5n = 1[/tex]

[tex]n = 0.2[/tex]

Q2:

Use the quadratic formula on your calculator.

Answer: T

Step-by-step explanation:

Answer:

p= 2

Step-by-step explanation:

So first you want to distribute the 6 to 3p-2 which basically means multiply

6(3p – 2) = 24

6 times 3p is 18 and 6 time -2 is -12

* remember a negative and a positive equal a negative*

18p-12=24

you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36

18p = 36

since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2

so p = 2

if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it  was like 18 + p you can subtract because 18 and p arent together

Answer:

Well you can’t really stack these percentages discounts.

Assuming it’s in the same order as the problem then

We can find the decimal equivalent by just dividing.

So think of it like this way.

Your getting 40 percent off, the original price.
The original price of course is a 100 percent since its the one and only price.

When your taking 0.4 percent off then its taking off 0.4 from the 1.00

So you have 0.6.

Your now paying 60 percent of the price.

Now the 30 percent.
Same thing except this times its 0.6.

Now 30 percent of 60 is 18 percent and then subtract that by 0.6 which is 0.42

Now for the final 15 percent
Same thing except this time its 0.15

15 percent of 0.42 is 6.3 percent, subtract that by 0.42 is 0.357

After the discounts were applied you’d only have to pay 0.357 or 35.7%

In order to find the total amount of discounts just subtract the amount we have to pay by the original which was 100 %. 100 - 35.7 = 64.3

Final net percentage is equivalent 64.3%

Answer:

[-8, infinity)

Step-by-step explanation:

Interval notation uses (, [, ], ) where the parentheses are exclusive and the brackets are inclusive. That means, we have:

[-8, infinity)

The reason we don't use the square bracket for infinity is because you can never include infinity in your set

(b) 7/10+5/100=75/100=75%

Answer:

a. 1.25

b. 75%

Step-by-step explanation:

Percentage to Decimal = Divide by 100

Decimal to Percentage = Multiply by 100

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be $782.10

The volume of a cylinder is expressed as:
V = πr²h

h is the height = 40ft

r is the radius  = 1.5/2 = 0.75ft

Substitute:

V = π(0.75)²(40)
V = 3.14 * (0.75)²(40)

V = 70.65 cubic foot

If the cylinders are made out of wood that costs $11.07 per cubic foot, the cost of the cylinder will be 11.07 * 70.65 = $782.10

Step-by-step explanation:

Answer:

{x,y} = {1,1}

Step-by-step explanation:

[2]    6y = -14x + 20

 [2]    y = -7x/3 + 10/3

// Plug this in for variable  y  in equation [1]

  [1]    -10x - 6•(-7x/3+10/3) = -16

  [1]    4x = 4

// Solve equation [1] for the variable  x

  [1]    4x = 4

  [1]    x = 1

// By now we know this much :

   x = 1

   y = -7x/3+10/3

// Use the  x  value to solve for  y

   y = -(7/3)(1)+10/3 = 1

Solution :

{x,y} = {1,1}

Answer: A

Step-by-step explanation:

The answer to this question is A. We know this because it is in slope-intercept form, there m is the slope and b is the y-intercept. In A, you can see that 1/3 is m and b is 2. This proves that A is the correct answer.
