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:
![(4x - 3)(5x - 8) = 20x^2 -47x + 24](https://tex.z-dn.net/?f=%284x%20-%203%29%285x%20-%208%29%20%3D%2020x%5E2%20-47x%20%2B%2024)
Step-by-step explanation:
Given
![(4x - 3)(5x - 8)](https://tex.z-dn.net/?f=%284x%20-%203%29%285x%20-%208%29)
Required
Identify and correct error
The error is when the inner and outer terms are multiplied. i.e.
not 32x
not 15x
So, the expression is:
![(4x - 3)(5x - 8) = 20x^2 - 32x -15x + 24](https://tex.z-dn.net/?f=%284x%20-%203%29%285x%20-%208%29%20%3D%2020x%5E2%20-%2032x%20-15x%20%2B%2024)
![(4x - 3)(5x - 8) = 20x^2 -47x + 24](https://tex.z-dn.net/?f=%284x%20-%203%29%285x%20-%208%29%20%3D%2020x%5E2%20-47x%20%2B%2024)
Answer:
7x -14 = jl
Step-by-step explanation:
Assuming a straight line
jm+ ml = jl
5x-8 + 2x-6 = jl
Combine like terms
7x -14 = jl
20.4 is greater than 0.75
