4:5:7
X1500
6000:7500:10500
Share 2 is $7500 and share 3 is $10500.
Each 1 in the original ratio is worth $1500, so you just multiply it by the corresponding number to get the answers.
X/y, y would be the 20 percent of course and x is the money earned
So for 9, to graph all you need to do is start at the origin (0,0) and go up 4 and over (right) 1.
Answer:
7
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 4² = (
)²
x² + 16 = 65 ( subtract 16 from both sides )
x² = 49 ( take the square root of both sides )
x =
= 7
That is the other leg is 7 units
