Answer:
24ab
Step-by-step explanation:
The multiple of 8, 2, 4ab, 3a, and 6b would be all the variables multiplied together right?
Then you see that:
8 can be divided by both 2 and 4 (2 x 2 x 2)
2 is 2 x 1
4ab can be 2 x 2ab
3a is the same as 3 x a
and
6b can be 2 x 3b
Now if you find the lowest common multiples (LCM's) of each variable with another you'll get your answer.
LCM of 8, 2 and 4ab is 2 times 2 times 1 times 2ab which equals 8ab
LCM of 3a and 6b is 3a times 2 times b which equals 6ab
and the
LCM of 8ab and 6ab is 2 times 2ab times 4 times 3 which equals 24ab.
Answer:
<u>y= -17</u>
Step-by-step explanation:
In order to solve for y you need to get y by itself on one side of the equation.
This is very simple and all you need to do is divide each side by -2.
![-2y=34](https://tex.z-dn.net/?f=-2y%3D34)
/-2 /-2
<u>y= -17</u>
34 divided by -2 is -17
Answer:
21.4 m²
Step-by-step explanation:
To find the surface area of this whole triangular prism, we have to look at the bases (the triangles), find their surface area, then look at the sides (the rectangles) and find theirs.
Let's start with the triangles. The area of any triangle is
. The base of this triangle is 2m (because there are 2 one meters) and the height is 1.7m.
![\frac{2\cdot1.7}{2} = \frac{3.4}{2} = 1.7](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ccdot1.7%7D%7B2%7D%20%3D%20%20%5Cfrac%7B3.4%7D%7B2%7D%20%3D%201.7)
So the area of one of these triangles is 1.7m. Multiplying this by two, because there are two triangles in this prism:
![1.7\cdot2=3.4](https://tex.z-dn.net/?f=1.7%5Ccdot2%3D3.4)
Now let's find the area of the sides.
The side lengths are 2 and 3, so
, and there are 3 sides (including the bottom/floor) so
.
Now we add.
m².

5 red, 3 yellow, and 2 blue....for a total of 10 marbles
P(first one being blue) = 2/10 which reduces to 1/5
not replaced
P(second one is blue) = 1/9...because u already pick a blue, meaning there is only 1 left, and there is one less marble, so there is a total of 9 marbles.
P(both events happening) = 1/5 * 1/9 = 1/45 <==
