Step-by-step explanation:
Remember the SAS rule is that you know the measure of 2 sides and their angle in between. (Note that SSA side side angle DOESN'T work.) For the first question we know that sides JH and LM are congruent, and sides GJ and MK are as well. Secondly, we know that angles M and J are congruent. The question is; does this problem follow the SAS (side angle side) rule? Yes, their are two proven congruent sides on the two triangles, and the angle between them is proven congruent as well.
Second one is congruent because it follows the SSS rule (side side side) ie: all sides are congruent, so therefore the triangles are congruent.
Think about the third one. Is it congruent or not. (To be congruent it has to follow SSS, or SAS) Comment below so I can correct you.

€1.25
Step-by-step explanation:
12
The floor area is found by multiplying its length by its width: 6*5=30
The amount of area covered by one tile is found by multiplying its length by its width: 3*w=3w.
Ten tiles are used to cover the floor, so the floor area should be equal to ten times the tile area:
10(3w)=6*5
30w=30
w=1
(not sure if youre meant to just have the equation or find w)
13
35°F is 13°F lower than the high temp. So, add 13°F to find the high temp.
35+13=48°F

Find the output, g, when the input, r, is 4.
g=25−3r
plzzzzzz help me i need to finish
Answer: g = 13 / Thats the output
Step-by-step explanation:
g = 25 - 3r
Its telling you the r is 4 since its the input.
g = 25 - 3 ( 4 ) see!! just plug in the number
Now Solve
g = 25 - 12
g = 13
Answer:
g = 13
Step-by-step explanation:
since r = 4, you make the equation :
g=25-3(4)
first you multiply 3 and 4 and you get 12
g=25-12
and 25 - 12 is 13 which equals :
g = 13

What is the probability of getting 2 of the same colour?
PLZ answer fast urgant help needed!
Answer:
0.5041 = 50.41% probability of getting 2 of the same colour
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability of getting 2 of the same colour?
Both blue or both red
Since they are replaced, we have, in each trial:
6 blue from a set of 6 + 5 = 11
5 red from a set of 6 + 5 = 11
Probability of both blue:
Each with 6/11 probability. So
[tex]P = (\frac{6}{11})^2 = \frac{36}{121}[/tex]
Probability of both red:
Each with 5/11 probability. So
[tex]P = (\frac{5}{11})^2 = \frac{25}{121}[/tex]
Total:
[tex]p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041[/tex]
0.5041 = 50.41% probability of getting 2 of the same colour
