The width of a rectangle is 5 feet, and the diagonal is 8 feet. Which is the area of the rectangle? (Round to nearest hundredth.

oee [108]

$The \ formula \ for \ the \ area \ of \ a \ rectangle \ is: \\\\A=l\cdot w\\ where \ l \ is \ the \ length, \ w \ is \ the \ width \\\\ w = 5 \feet , \\ diagonal: \ d= 8 \ feet \\ \\ apply \ the \ Pythagorean \ Theorem:$

$d^2=w^2+l^2 \\ \\l^2=d^2-w^2\\\\l^2=8^2-5^2\\\\l^2=64-25\\\\l^2=39$

$l=\sqrt{39}\\\\l \approx 6.244998 \ feet\\\\A= 6.244998 * 5= 31.22499\approx 31.23 \ feet^2$

Billy has 2 cats and one of them ate 3 oatmeal bowls. If they both eat 3 oatmeal bowls how much sugar should they all together h

9966 [12]

3 x (2/3) = 2

2 x 2 = 4

If both cats eat 3 oatmeal bowls, they should have 4 cups altogether.

2 x 23.8888 = 47.7776

4 x 23.8888 = 95.5552

47.7776 + 95.5552 = 143.3328

If one cat eats 2 fish plates and the other cat eats 4 fish plates, they use 143.3328 pounds altogether.
