Answer:

8

Step-by-step explanation:

Let the number be n

6*n = 16 + 4*n

6n = 16 + 4n

6n - 4n = 16

2n = 16

2n/2 = 16/2

n = 8

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

first you have to find the slope of the original question

2x+2y=-8

2y= -8 -2x

y= -4-x

slope = -1

to find the perpendicular slope you flip it and multiply by -1

-1 -> -1 *-1 -> 1

Answer: not congruent

Step-by-step explanation:

To know if CD and EF are congruent, you need to use the distance formula to find CD and EF. If the distance is the same, then they are congruent.

Distance formula: [tex]d=\sqrt{(x_{2}-x_1)^2+(y_2-y_1)^2}[/tex]

CD

[tex]d=\sqrt{(-4-(-4))^2+(3-(-5))^2}[/tex]                [parenthesis]

[tex]d=\sqrt{(0)^2+(8)^2}[/tex]                                           [exponent]

[tex]d=\sqrt{0+64}[/tex]                                                   [add]

[tex]d=\sqrt{64}[/tex]                                                         [square root]

[tex]d=8[/tex]

------------------------------------------------------------------------------------------------------------

EF

[tex]d=\sqrt{(-8-(-3))^2+(2-2)^2}[/tex]                      [parenthesis]

[tex]d=\sqrt{(-5)^2+(0)^2}[/tex]                                        [exponent]

[tex]d=\sqrt{25+0}[/tex]                                                  [add]

[tex]d=\sqrt{25}[/tex]                                                        [square root]

[tex]d=5[/tex]

------------------------------------------------------------------------------------------------------------

After finding the distance of CD and EF, we can say that they are not congruent. The line CD is 8 units long and line EF is 5 units long. Therefore, they are not congruent.

Answer: There are several information's of immense importance already given in the question. Let us write them down first.

Diameter of the cylinder = 6 inches

Then

Radius of the cylinder = 3 inches.

Height of the cylinder = 3 * radius

                                  = 3 * 3

                                  = 9 inches

Volume of the cylinder = (pi) * (Radius)^2 * Height

                                   = 3.14 * (3)^2 * 9

                                   = 3.14 * 9 * 9

                                   = 254.34 cubic inches

B (5,1)

Answer:

B

Step-by-step explanation:

In 45 45 90 triangles the ratio is a:a:a root 2 so the answer would be 3root 2/2 or c because when multiplied again by root 2 it will get you 3.

"Product" means multiply.

The product of a number z and 12: z * 12 or 12z

Put everything we know together.

12z = 60

Solve for z if needed

12z/12 = 60/12

z = 5

Best of Luck!

Answer:5

z x 12=60

z=60/12

z=5

Answer:

5

Step-by-step explanation:

The distance between the points (4,3) and ( 0,6) is; d = 5

The formula for distance between two coordinates is given as;

d = √((y2 - y1)² + (x2 - x1)²)

We are given the coordinates;

(4,3) and (0,6)

Thus;

x1 = 4

x2 = 0

y1 = 3

y2 = 6

Thus;

d = √((6 - 3)² + (0 - 4)²)

d = √(3² + 4²)

d = √25

d = 5

1/2n= 16

n= 16*2

n=32

Answer:

[tex]n=32[/tex]

Step-by-step explanation:

Answer:

m=1

Step-by-step explanation:

step 1: 8(m + 2) = 3(12 - 4m) remove the parentheses

step 2: 8 m + 2 = 3 12 - 4m move the terms

step 3: 8m+ 12m= 36 - 16 collect like terms and calulate

step 4: 20m=20 divide both sides

solution: m=1

Answer:

m = 1

Step-by-step explanation:

To solve for m, we will have to get m by itself on one side, with some value on the other side.

8(m + 2) = 3(12 - 4m)

Distribute the 8 on the left side and the 3 on the right side.

8m + 16 = 36 - 12m

Add 12m to both sides.

20m + 16 = 36

Subtract 16 from both sides.

20m = 20

Divide both sides by 20.

m = 1

So now we have the answer m = 1.

Step-by-step explanation:

Answer:

05.

Step-by-step explanation:

trust me dude i just took this question :D

The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15 so option (D) will be correct.

Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

Do not take underestimate probability it has several uses in daily life whether forecasts or like that.

Total number of candles = 12 + 8 + 20 = 40

Probability = desire/total

So,

Probability of taking lavender first = number of lavender/total

⇒ 12/40 = 0.3

Now since we again put the lavender into the lot it means all things remain the same.

Probability of rose-perfumed second = number of rose-perfumed /total

⇒ 20/40 = 0.5

Now the probability of A and B is the multiplication of the probability of A and B individually.

So,

The probability of taking out lavender and a rose-perfumed candle

⇒ 03 × 0.5 = 0.15

Hence "The probability of taking out lavender and a rose-perfumed candle with replacement is 0.15".
