Answer:
46.16 years
Step-by-step explanation:
(correct equation with missing symbols: h = 62.5 * (^3√t) + 75.8)
To find the age of an elephant that has a shoulder height of 300 centimeters, we just need to use the value of h = 300 in the equation, and then find the value of t:
h = 62.5 * (^3√t) + 75.8
300 = 62.5 * (^3√t) + 75.8
62.5 * (^3√t) = 224.2
^3√t = 3.5872
t = 3.5872^3 = 46.16 years
The age of the elephant is 46.16 years.
Answer:
Step-by-step explanation:
Add the unshaded parts and subtract the result from 1 ( whole circle )
+ ( the LCM of 2 and 9 is 18 )
= +
= +
=
shaded = 1 - = - =
5x+3y=-9
-2x+y=8
The first step is the trickery (and quite frankly, hardest to explain) part. You need to multiply one equation by a number that will create one variable to be the negative version of the other...(Confusing, right? Don't worry, I'll show you)
We are going to solve for X first.
We will multiply the second equation by -3
5x+3y=-9
-3(-2x+y)=(-3)8
Now simplify:
5x+3y= -9
6x-3y= -24
Now combine the two equations (add them together)
11x= -33
Divide by 11
X=-3
Now plug X in to one of the first equations:
5(-3)+3y= -9
-15+3y =-9
3Y= 6
Y= 2
So your final answer is:
x= -3
Y= 2
Hope this helps!
