Answer is below. Look at the explanation to understand my answer.
To multiply fraction, you'll need to multiply the numerator by the other numerator and the denominator by the other denominator. You don't need to make the denominators common.
Normally you'll multiply the numerator and the denominator, but for this, 12 is a whole number. To convert it into a fraction, put 1 as the denominator.
12 will now be ¹²⁄₁.
Remember, you don't need to make common denominators. Only for subtracting and adding fraction with unlike denominators.
Our problem will be like this: [tex]\frac{12\times3}{1\times8}[/tex]
With that being said, let's solve.
12 times 3 equals 36.
1 times 8 equals 8.
Our answer is ³⁶⁄₈, but it is improper. We will need to convert it into a mixed number by dividing the numerator by the denominator.
Find the Greatest Common Factor (GCF) of 36 and 8. If there is, reduce the fraction dividing both numerator and denominator by it.
Therefore, the GCF is 4.
Whatever you do to the top, You do to the bottom.
Our problem will be this: [tex]\frac{36\div4}{8\div4}[/tex]
36 divided by 4 is 9.
8 divided by 4 is 2.
Hence the fraction is ⁹⁄₂, but the fraction is still improper. Instead of finding the GCF, we will use long division.
We will divide 9 by 2 to get the answer.
9 divided by 2 is 4 with a reminder of 1.
The reminder will be the numerator, the denominator will be the same, and the quotient, or the answer will be the mixed number.
Therefore, our final answer is 4 ½.

You randomly choose one of the four marbles. Without replacing the first marble, you choose a second marble. there are 1 blue, 1 green, 1 yellow, and 1 red. Use tree diagram
Answer:
12 total possible outcomes
Step-by-step explanation:
To do this, we can use the Fundamental Counting principle, which is :
An event M has m possible outcomes. An event N has n possible outcomes. The total number of outcomes of event N followed by event N is m x n.
When you first pick up a marble (event M), there are 4 possible outcomes (yellow, red, green, blue). Since you do not replace the marble, when you pick the second time (event N) there are only 3 other possible colors.
As we know, m x n = to total possible outcomes.
So, 4 x 3 = 12 total possible outcomes.

Answer:
A = 168 m²
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 = 8 + 16 = 24 and h = 14 , then
A = [tex]\frac{1}{2}[/tex] × 24 × 14 = 12 × 14 = 168 m²

Hi, there your answer will be y=2x-4
Step-by-step explanation:
Well finding the y-intercept you have to see what goes through the y-axis in this case it is -4
To find the slope you can do [tex]\frac{rise}{run}[/tex]
or you can use the slope formula which is
[tex]\frac{y2-y1}{x2-x1}[/tex]
In this case, I'll be using the slope formula I'll pick two coordinate which are (0,-4) and (3,2). I'll be plugging that in
[tex]\frac{2-(-4)}{3-0}[/tex]=[tex]\frac{6}{3}[/tex]
We will simplify [tex]\frac{6}{3}[/tex] which will equal to 2
Hope this helps :)

Geoffrey wants to make one planter that extends from the ground to just below his back window. The window starts 3 feet off the ground. If he wants the planter to hold 36 cubic feet of soil, name one way he could build the planter so it is not taller than 3 feet. Explain how you know.
Answer:
Step-by-step explanation:
36 / 3 = 12
12 = 4 x 3
V = L x W x H
= 4ft x 3ft x 3ft
=
Since Geoffrey wants to build a planter with a height of 3ft & a volume of 36ft^(3), the base of the planter should have an area of 12ft^(2).
