ANSWER
6.4 hours
EXPLANATION
if it takes 10 hours to get 50%, then it will take less number of hours to get 32%
We use proportion to solve this question.
If less more divides.
The number of hours it will take to get 32% is
Hence it will take 6.4 hours to get 32%
Answer:
8674247
take the first number and write it
I think the answer is C. 5^4 because I think it should equal a positive?
Answer:
- inscribed angle: 30°
- central angle: 60°
Step-by-step explanation:
The central angle is double the inscribed angle for the same intercepted arc. Since doubling the angle adds 30° to it, the original inscribed angle must be 30°.
Then the central angle is 30°+30° = 2·30° = 60°.
ANSWER
The coefficient of y is
EXPLANATION
The first equation is
We can rewrite this equation in the slope intercept form to get,
We divide through by 10 to get,
The slope of this line is
and the y intercept is
Let
be the coefficient of y in the second equation.
Then, we have
We rewrite this equation too in slope intercept form to get,
Dividing through by
gives,
For the two equations to have infinitely many solution, then they must have the same slope and y intercept.
This means, that,
This implies that
Therefore the coefficient of y must be 2.
