Answer:

Step-by-step explanation:

Hi there!

We want to find the least common multiple (LCM) of 12 and 18

One easy way to do that is to split up the numbers into one of their factor pairs, find the factor pairs between the numbers we just split apart, and then keep on going, until we only get prime numbers (numbers that only have 1 and itself as multiples)
Let's start with 12.

There are multiple ways to multiply to get to 12, but we can use 3 and 4 for example

12= 3*4

4 is 2 * 2  

Substituting 2*2 for 4, 12 is equal to 2*2*3

Now for 18.

18 can also be split up multiple ways; one way would be 9 and 2

18 = 2*9

9 is 3*3

Substitute 3*3 for 9.

18=2*3*3
Now look at 2*2*3; 2 shows up twice in that string of numbers

In 2*3*3, 3 shows up twice in that string of numbers

We multiply the numbers based off of the highest number of times that they occur
In other words, we will multiply 2 * 2  and 3 * 3 together
2 * 2 * 3 * 3 = 4 * 9 = 36
The LCM of 12 and 18 is 36

Hope this helps!

Answer:

π(36x^2 - 120x + 100)

Step-by-step explanation:

4π(3x - 5)^2 = 4π[(3x)^2 - 2*3x*5 + 5^2] = 4π(9x^2 - 30x + 25)

= π(36x^2 - 120x + 100)

Answer/Step-by-step explanation:

1. x = -3.6

Add 1 on both sides.

18x = 23x + 18

Subtract 23x on both sides.

Combine like terms.

Divide the answer.

-5x = 18

x = -3.6

2. x = 11/3 (2.66666...)

Add 5 on both sides.

6x = 3x + 11

Subtract 3x on both sides.

Combine like terms.

Divide the answer.

3x = 11

x = 11/3

3. x = 23

Subtract 12 on both sides.

5x = 6x - 23

Subtract 6x on both sides.

Combine like terms.

Divide the answer.

-x = -23

x=23

(that's all.)

Answer:

18.8 years

Step-by-step explanation:

8% of $2000 = $160

To be worth $5000, the painting need to rise by $3000
And every year it rise by $160, so it will need 3000 : 160 = 18.75 (round to 18.8) years.

Answer:

s = 71

j = 23

71 = 3j+2

71 - 2 = 3j

39 = 3j

j = 23

Answer:

j=23

s=71

Step-by-step explanation:

Here we have two parallel lines lines( UB and DK).

And we have another line, called a transversal that intersects( crosses) both parallel line. Doing so creates the following angles,

So now we look at the graph

First, we know that 3j+2 and s are vertical angles since they are across of each other. So they are equal to each other so let look at another angle first.

3j+s and 71 are Alternate Interior Angles since they lie inside the transversal and are across from each other.

Since they are Alternate Interior Angles, they are equal.

So we set them equal to each other.

[tex]3j + 2 = 71[/tex]

Subtract 2 from both sides

[tex]3j = 69[/tex]

Divide both sides by 3

[tex]j = 23[/tex]

The value of j is 23.

Know to find S, we know s is equal to 3j+2, which when we plug in 23 for j, we get 71.

So s=71

Answer:

He flew for 3 hours

Step-by-step explanation:

in this question we can use the formula :

[tex] \boxed{t = \frac{s}{v}} [/tex]

t is time

s is distance

v is Speed

_________________

We know that :

v = 12 miles/hour

s = 36 miles

So :

[tex] t = \frac{s}{v} = \frac{36}{12} [/tex]

[tex] \boxed{t = 3 \: hours}[/tex]

tan(47)=53/z

Step-by-step explanation:

Using trig ratio tan(x)=O/A

there x is the angle of elevation, O is the side opposite the angle (the lighthouse) and A is the side adjacent the angle (distance between boat and bottom of lighthouse)

Therefore, tan(47)=53/z
