450 g in 2:13
<u>Total proportion asked for </u>=2+13=15
<u>Now comparing g with ratio, or whatever </u>
450/15=30g 
Therefore 1 in ratio depicts of 30g
So final answer = 
More to know, daily bit of knowledge: The Binomial Theorem:
The cable should be 50 feet.
If you draw the picture, you will see that you have a right triangle.
Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).
30^2 + 40^2 = c^2
2500 = c^2
50 = c
Answer:
L/2
Step-by-step explanation:
If the width is half of its length, that means it is 1/2*L, as L is the length. This can be simplified into L/2, which is our answer.
Answer:
x^2\ 16 - y^2/9 = 1
step-by-step explanation:
soooo the equation for a hyperbola that is horizontal is x^2/a^2 - y^2/b^2 = 1
a hyperbola should always equal one so dont forget that when writing your equation becuase it is easy to forget.
it helps to graph this so you can see it better
to find a it is the distance from the center to the vertices which is 4 so in the equation you will write 16 becuase it is a^2
then you need to find b. to get b you have to figure out that c is the distance from the center to the foci which is 5 and it is all related to the plythagorm theorum becuase it forms a right triangle. so you do c^2 - a^2 = b^2
you get 9 for b^2 because 25-16=9 and so you put that in the equation
