Answer: 680
Step-by-step explanation:
3 parts are male and 1 part is female. This adds up to 4 parts = 1360
3 part - 1 part (male - female) = 2 parts of the original which is 1/2 of 4 parts
1/2 of 1360 = 680

Answer:
x = 80
Step-by-step explanation:
Total = 360
90 + 50 + 90 + 50 = 280
360 -280 = 80
The sine of an angle in a right triangle is the ratio of the length of the opposite side to the length of the hypotenuse
If
<span>, then:
</span>opposite = a² - b²
hypotenuse = a² + b²
<span>By the Pythagorean theorem:

If the weight of the bottom box is b then the weight of a stack of four boxes is b + b/2 + b/4 + b/8
= 8b/8 + 4b/8 + 2b/8 + 1b/8
= 15/8 b
A stack must weigh less than 100 pounds
15/8 b < 100
b < 100 x 8/15 = 53 1/3 pounds
If boxes have a minimum weight of 1 pound then
for stacks that contain 4 boxes the range of b is [8, 53 1/3)
and if stacks contain 1 to 4 boxes the range of b is [1, 53 1/3)
If the only restriction is a maximum of 100 then the range of b is [0, 53 1/3)
