1) Draw the triangles JKL and J'K'L' in a same coordinate system.
When I did that, I realize the if you translate the triangle JKL 1 unit left and then you reflects the image across the x-axys you get the you get the triangle J'K'L'.
So, select the boxes in that same order:
1) translation 1 unit left
2) reflection across the x - axis.
2) The answer ot the second question is line r.
That is called the line of reflection because if you reflect the figures through it you will have the same figure.
Answer:
100 minutes
Step-by-step explanation:
Set up a proportion where x is the amount of minutes it will take her to make the 50 inch long scarf:
= 
Cross multiply and solve for x:
35x = 3500
x = 100
So, it will take her 100 minutes to make Shannon's scarf
Answer: 52
Step-by-step explanation:
cos=7/11.4 -> cos-1(cosB) = cos-1(7/11.4)
m<B = cos-1(7/11.4) = 52
Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9
Step-by-step explanation:
How do you calculate number of successes?
Example:
Define Success first. Success must be for a single trial. Success = "Rolling a 6 on a single die"
Define the probability of success (p): p = 1/6.
Find the probability of failure: q = 5/6.
Define the number of trials: n = 6.
Define the number of successes out of those trials: x = 2.
