33.3 because 27/50=36/x and x=66.67 and thats how much as decayed after 36 hours but you want what is left so subtract from 100 and get 33.3
Answer:
12
Step-by-step explanation:
Let the total number of donuts in the pack be x.
Amy = 2/3x
Anna = 1/4x
David = 1
x - 2/3x - 1/4x = 1
Find common denominators for 2/3 and 1/4
The common denominator is 12
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
x - 8/12x - 3/12x = 1
x - 11/12x = 1
1/12x = 1
x = 12
You can always check
Amy = 8
Anna = 3
So David must equal to 1
Hope this helps :)
Have an awesome day!
Assuming the x stands for multiplication... follow the ordering rules:
First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:
3x16 - 36 + 4 - 6x4
Now do the multiplications:
48 - 36 + 4 - 24
The rest is just addition and subtraction
48 - 36 + 4 - 24 = -8
Answer:
B and D
Step-by-step explanation:
I don't have much of an explanation, but I remember from taking geometry that those two angles are the same measurement because they're congruent interior angles. hope this helps :)
