<span>apples = (50+x)(800-10x)
= (40000-500x+800x-10x^2)
= -10x^2 +300x + 40000
Max occurs when x = -b/(2a) = -30/(-2) = 15
= -x^2 + 30x + 4000
Max occurs when x = -b/(2a) = -30/(-2) = 15
15 trees should be added</span>
Answer:
According to the associative property of equality: (a + b) + c = a + (b + c) we can see that the parenthesis do not mean anything when we are only doing addition.
So answers 1. and 3. are correct.
Step-by-step explanation:
Answer:
<em>66°</em>
Step-by-step explanation:
mJK = ( 6x - 45 )°
mJH = ( x + 20 )°
mJK = mJH
6x - 45 = x + 20
5x = 65
x = 13
mHK = ( x + 20 )° + ( 6x - 45 )°
<em>mHK =</em> 2 × 33° = <em>66 </em>°
Answer:
numbers less than 5 are 1,2,3,4 and equal to 5 is 5.
probability of less than 5 is 4/16
while equal to 5 is 1/16
or means additions; so its 4/16 +1/16=5/16
