Answer: hypotenuse and leg of one right triangle
Step-by-step explanation:
The HL Postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.
Answer:
Step-by-step explanation:
A=πr2
= (3.14)(27)2
= 2289.06
6.98 divide it by 1.86= 3.75268...
(you rounded to 3.75 pounds)
1) The population
Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.
2) The sample is every set of five cards that is selected by each student.
3) I think the sample is representative because all ther terms have the same probability of being selected.
Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.
Wow! I never had problems this hard in middle school!
But you can do it!
First, we need to figure the number of flips Sara can do based on Jenny's.
Jenny = 120 and Sara - 120 x 3/8 (because she is only 3/8 of Sara's)
Calculate 120 x 3/8 = 45 flips
Now we know that Sara increased her amount of flips by 3 (45 +3 = 48)
And we know that Jenny decreased hers by 12 (120 - 12 = 108)
So now we have a ratio of 48:108, but we need to simplify that with factoring.
I am going to divide first by 2.
24:54
Then 2 again...
12:27
How about 3?
4:9
I think that is as far as we can go.
Sara is now doing 4 out of every 9 that Jenny does.
Check it!
108 (Jenny) x 4/9 = 48 (Sara) Yes! It checks.
