Answer:
a=-2
Step-by-step explanation:
Let me know if you need the steps tho.
1/4 = 2/8. Remember that. This means that 1/8 is equal to half of a month. It there is 5/8, you can add a half month for every eights. In this case, it will take 2 and a half months
Easy Way:<span>If your hair were to grow 1/4 inches a month, it would also grow 2/8 inches a month, since 1/4 = 2/8. How long with it take 1/8 (0.5/4)inches to grow? It would take a half of a month for your hair to grow 1/8 inches.
</span><span>Now that we know 1/8 inches grows in a half of a month, we add a half of a month for every eigths. Since we are trying to figure out how long it would take for it to grow 5/8 inches, we add 5 half months to get the answer of 2 and a half months. Kind of confusing, but that is the best way I can describe it.</span>
In a sample of digits(0,1,2,3,4,5,6,7,8,9,) what is the probability that a digit is 7 or greater
ad-work [718]
Answer:
Step-by-step explanation:
There are 10 numbers in total. Only three are 7 or greater: 7, 8, 9.
So the answer is .
Answer:
Side length = 
cm , Height = 
cm , Volume = 
cm³
Step-by-step explanation:
Assume
Side length of base = x
Height of box = y
total material required to construct box = A ( given in question)
So it can be written as
A = x² + 4xy
4xy = A - x²
Volume of box = Area x height
V = x² ₓ y
V = x² ₓ ( 
)
V = 
To find max volume put V' = 0
So taking derivative equation becomes
A = 3 
= 
x = 
put value of x in equation 1
y = 
y = 
y =
So the volume will be
V = × y
Put values of x and y from equation 2 & 3
V = 
V =
