No. Two angles will have to be the same and the third angle will just be 180° minus twice the smaller angles.
So if we let the equal angles equal a, and the large angle equal be we have:
2a+b=180
So there are infinitely many values that a and b can have.
a=(180-b)/2, so the smaller equal angles have the range (0,90)
b=180-2a, so the larger has a range of (0,180)
N can be 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 over or under the correct amount
Answer:
-9/16 > -7/10
Step-by-step explanation:
Carlita was either sipping the hot chocolate while she was out, or else
approximating the numbers. The exact number she reported is not
possible. To see why, I'll do it strictly by the math:
Robins = 5 times
Cardinals = 1 time
Total birds = 6 times
6 times = 25 birds
Divide each side by 6 : 1 time = 25/6 = 4-1/6 birds
Robins = 5 times = 20-5/6 of them
Cardinals = 1 time = 4-1/6 of them
Total: (20-5/6) + (4-1/6) = 25 birds.
How many more robins than cardinals = (20-5/6) - (4-1/6) = 16-2/3 more.
The math works out fine. But if the numbers she reported are true,
then some of what she saw was partial birds ... legs, or feathers,
things like that. Eeeew. I don't want to talk about it.
Answer:
The least score the student can get is 71 to get an overall B average at the end of the year.
Step-by-step explanation:
Let the score she needs to get be = x
We now have to take the mean of all the five subjects <em>(including x)</em> and equate it to the least score she can have to get a B grade.
Let us take the least score the student needs to get a B grade to be 85
Mean of all 5 scores =
The least score the student can get is 71 to get an overall B average at the end of the year.
