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
Answer:

Step-by-step explanation:
The equation of a circle is:
, where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.
In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:

If you want, you can round 4.3589^2 to 19.
Then, the answer would be:
.
Hope this helps!
Answer:
The correct option is B.
Step-by-step explanation:
In a program the variables are defined as
int a, b =2;
float c = 4.2;
The given statement is
a = b * c
a = 2 * 4.2
a = 8.4
It is given that variable a is an integer. So, only integer value can be stored in a.
a ≈ 8
It means 8 will be stored in a. Therefore the correct option is B.
