Example: 5 x 2 / 5 + (6 x 3)
1. Evaluate parentheses: 6 x 3 = 18
2. Multiply and divide: 5 x 2 = 10, 10 / 5 = 2
3. Add and subtract: 2 + 18 = 20
4. We're done: 20
Answer:
15.6 ft
Step-by-step explanation:
Since the sails are similar then the ratios of corresponding sides are equal.
Comparing the shortest sides, that is
10 : 6 = 5 : 3
let the longest side be x, then using proportion
=
( cross- multiply )
5x = 78 ( divide both sides by 5 )
x = 15.6
The longest side is 15.6 ft
Well we can say 10.90/10 = the cost per pound to ship the item
we can infer this from the above text so
10.90/10 = 1.09.
So 1.09 * 37 = 40.33
$40.33
or 40 dollars and 33 cents to ship the second box with a weight of 37lb (pounds).
You need to know atleast 2 of three sides from a triangle, or 1 side and 1 angle of a triangle. Then you can use trigonometry to find the angle needed.
