Answer:
The answer is -14.
Step-by-step explanation:
Just divide -7 by 0.5
Information given to us:
10 4/5 total cake batter
18 cupcakes
First, we need to find the improper fraction of 10 4/5, which is 54/5. Now we can divide 54/5 by 18. Answer: every cupcake will use 3/5 cup.
You can use trig here - you want to know the angle opposite from the shortest side, which we'll call "A," and you have the sides that touch the right angle. side A (21 inches) and side B (25 inches) intersect at a right angle, so the side we're missing is the hypotenuse. the angle across from side A is angle "a" - now, since we know which side is the hypotenuse, we can figure out which trig function works here. angle "a" can be found by doing tan(a)=Opposite/Adjacent --> tan(a)=A/B --> tan(a)=21/25 --> a=tan^-1(21/25). a = 40.03 degrees
Answer:
±1/30
Step-by-step explanation:
Notice that both 16 and 14400 are perfect squares; 16 = 4² and 14400 = 120².
Thus, √(16/14400) = √(4/120)² = ±4/120 = ±1/30.
This is the set of square roots of +16/14400.
The square roots of -16/14400 are ±i(1/30) (which are imaginary roots).
Answer:
x > - ![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
Step-by-step explanation:
Given
x > - ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Multiply both sides by 10 to clear the fractions
12x > - 15 ( divide both sides by 12 )
x > -
, that is
x > - ![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
