Answer:
none
Step-by-step explanation:
Hi, I hope this helps, I'm in high school LOL.
Use these, they help to figure this out:
a + b > c
b is the longest side, or hypotenuse. c would be the base.
We have to make sure that c is less than what a + b is.
Plug the numbers in:
2.7 + 4.8 > 8.6
4.8 plus 2.7 is 7.5 cm.
So, 7.5 > 8.6
Obviously, 7.5 is less than 8.6 so 7.5 > 8.6 <u>does not work at all. </u>
That tells you that no triangles can be formed. So, it's none.
The period is found in one full cycle of the function. One "up-down-up", if you will. Our function starts below the x axis, so one full cycle goes from down to up to back down to back up. This up-down-up is complete at 3pi. So your answer is the third choice down.
Answer:
She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
Factor out the common term 55
5(x+y)=10
Divide both sides by 55
x+y=10/5
Simplify
Subtract y from both sides
<u>x=2-y </u>
Answer:
There are 25 reindeers and 17 snowbirds
Step-by-step explanation:
A reindeer has 4 legs while a snowbird has two legs
Let the number of reindeer be x while the number of snowbirds is y
Total heads is 42;
x + y = 42 •••••••(i)
let’s now count the legs
4(x) + 2(y) = 134
4x + 2y = 134 ••••••(ii)
divide ii by 2
2x + y = 67
y = 67 - 2x
and from i above too, y = 42-x
equate the y
67-2x = 42-x
67-42 = -x + 2x
x = 25
y = 42-x
y = 42-25
y = 17
