Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
Answer:
1.x=-4+ y/2 - z/2
2. X=-4-y-z
3. x=y/3-2/3
Step-by-step explanation:
Divide your shape into two different shapes. a cube and a rectangular prism.
the cube has the measurements of 20*20*20 giving it a volume of 8000 inches^3
the rectangular prism has the measurements of 40*30*20 giving it a volume of 24000 inches^3
now add them together to get 32,000 inches^3 as your answer

Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease
