Answer:

71 boxes

Step-by-step explanation:

1. Add 522 (# of glaze donuts) and 323(# of chocolate covered donuts).....845(# of total donuts)

2. Divide 845 by 12(the # of donuts each box could hold)....70.41666(repeating)

3. As you can't have a 0.41666 of a box, you round up 70.4166666 to 71.

71*12=852 70*12=840

Even though 71 boxes is more than enough to hold 845 donuts, there is simply no other choice, as there is no smaller box that holds less than 12 donuts.

guajiro [1.7K]

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

20 POINTS and it has to be correct. This depends on if I pass or fail
valentina_108 [34]

Answer:

(x+8)^{2}+(y-14)^{2}=19

Step-by-step explanation:

The equation of a circle is: (x-x_1)^{2}+(y-y_1)^{2}=r^2 , 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:

(x+8)^{2}+(y-14)^{2}=4.3589^2

If you want, you can round 4.3589^2 to 19.

Then, the answer would be: (x+8)^{2}+(y-14)^{2}=19 .

Hope this helps!

Assume a program has the following variable defenition: int a, b =2; float c = 4.2; and the following statement: a = b * c; What
Vladimir [108]

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.
