Answer:
8.47 Hours
Step-by-step explanation:
Allen can take 16 hours, while
Brianne can take 18 hours;
Therefore, in 1 hour Allen will complete a fraction of 1/16, while
in 1 hour Brianne will complete a fraction of 1/18
When working together, in 1 hour they will complete a fraction of (1/18+1/16)
= 17/144,
Therefore; to complete the whole project working together, they will take;
144/17 = 8.47 hours
where is the figures to solve.
256 are needed because 32x1=32 that means the ratio would be 32:256 because 8 x 32 = 256
The final ratio would stay the same as 1:8 though because it would be simplified.
Hope this helped.
Answer:
-3 is the coefficient of c.
Step-by-step explanation:
The given expression is :
9a³ + 4b² - 3c + 11
We need to find the term with coefficient -3 in the expression.
The coefficient is defined as a number or quantity placed with a variable.
The coefficient of a³ = 9
The coefficient of b² = 4
The coefficient of c = -3
Hence, -3 is the coefficient of c.
