Mathematics: Julia bought 18 apples at the store. she then divided up the apples between her mother, her father, and herself in a ratio of 2: 1: 3. that means her mother received two parts, her father received one part, and julia received three parts of all the apples. how many apples did each person receive?

Add up 2, 1 and 3. Result: 6.

Mother received 2 parts out of 6, or (2/6)(18) = 6 apples;

Father rec'd 1 part out of 6, or (1/6)(18) = 3 apples, and Julia herself rec'd (3/6)(18), or 9, apples.

Mathematics

$4.5\pi\approx 14.14$ square feet.

Step-by-step explanation:

We have been a table with a round top is cut in half so that it can be used against a wall. After it is cut, the edge along the wall is 6 feet .

When we will cut the round table into half, it will result in a semicircle.

The area of half the table will be equal to area of semicircle. We know that area of semicircle is half the area of circle.

$\text{Area of semicircle}=\frac{\pi r^2}{2}$

$A=\frac{\pi(3)^2}{2}$

$A=\frac{9\pi}{2}$

$A=4.5\pi$

$A\approx 14.14$

Therefore, the area of the table would be $4.5\pi\approx 14.14$ square feet.
