Okay, first we need to figure out what one would make. We need to figure out the area of the base x height. The diameter is 8 so we will cut that to 4 so we can do piR2! 3.14x16 would be 50.24. Then we mutiply that by 10 to get 502.4cm3! Okay, now we would divide 2000/502.4 to find out how many times we would have to make the containers to get to 2000. The answer is 3.98, which we will have to round up since its asks for the minimum and you cant make a container 3.98 times. So the answer is 4!

Christian has a cookie recipe that yields four dozen cookies and calls for 2 1/4 cups white sugar and 3/4 cup brown sugar.cif ch
Paha777 [63]

The ingredients given are for 4 dozen cookies; however, Christian only want to make one dozen, meaning he requires only 1/4 the ingredients.

1/4 of 2 1/4 cups of while sugar is found the following way.

First, we write 2 1/4 as an improper fraction

2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}

1/4 of this is

\frac{9}{4}\times\frac{1}{4}=\frac{9}{16}

Hence, Christian requires 9/16 cups of white sugar.

Similarly, the 1/4 of 3/4 cups of brown sugar is

\frac{1}{4}\times\frac{3}{4}=\frac{3}{16}

Hence, Chrisitan requires 3/16 cups of brown sugar.

Therefore, the total cups of sugar required is the sum of

\frac{3}{16}+\frac{9}{16}=\frac{12}{16}=\frac{3}{4}

3/4 cups of sugar.

If school normally begins at 8:10 a.m. and we have a two hour delay, what time should we go to school?
Burka [1]
For this, you've just got to add 2 hours to 8:10, 8+2=10. Therefore, school would begin at 10:10am if there was a two hour delay :)
