Answer:
see explanation
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition when y = 30, x = 6
k =
=
= 5
y = 5x ← equation of proportionality
When x = 12, then
y = 5 × 12 = 60
Given that t<span>he
area of the mojave desert is 25,000 square miles and a scale drawing of
the mojave desert has an area of 10 square inches.
The scale of
the map is given by
![\sqrt{25,000} : \sqrt{10} = \sqrt{2,500\times10} : \sqrt{10} \\ \\ =50 \sqrt{10} : \sqrt{10} =50:1](https://tex.z-dn.net/?f=%20%5Csqrt%7B25%2C000%7D%20%3A%20%5Csqrt%7B10%7D%20%20%3D%20%5Csqrt%7B2%2C500%5Ctimes10%7D%20%3A%20%5Csqrt%7B10%7D%20%20%5C%5C%20%20%5C%5C%20%3D50%20%5Csqrt%7B10%7D%20%3A%20%5Csqrt%7B10%7D%20%3D50%3A1)
Therefore, the scale of the drawing is 50 : 1.

The options 1 , e^2 is not the best choice to choose.
2 ln e, if it will be input on the scientific calculator the answer will still be 2. It is because of a property of logarithms.
The answer for ln e^2 is 2.
Answer:
1 and 12/25
its over 100 percent, that's where the 1 comes from. the 48 that's left would be 48/100, which is then simplified to 24/50, which is simplified one more time to 1 12/25
