1 2/3 - 1/4
you need to change the denominator for both
2/3 into 8/12 and 1/4 into 3/12
1 8/12 - 3/12
1 5/12
By subtracting 1/4 from 1 2/3 cups of flour, it's 1 and 5/12 cups.
Is this what the recipe calls for?
A triangle can't have two right angles because there is 180° in a triangle. Each right angle is 90° so it would be impossible
First question answer is B.
Second question answer is D.
3^2 = 9, 7 x 9 =63
**In case you're wondering why 3 square root 7 equals to square root 63.
Hope this helps.
[0, ♾) is the range of the function
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
