The equation for surface area is: $A= \pi r(r+ \sqrt{h^2+r^2}$ . To get r, you must use Pythagorean theorem. r is found to be 45. This means after you plug it in, you get about 13571.68

Step-by-step explanation:

All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

TRANSLATE EACH SENTENCE INTO AN EQUATION.

The Pacific Ocean = 46% of Earth (P = 46%)
The Land on Earth = 54% of Earth (E = 54%)

One Fence Per Yard = $1.75

$73.50 - $3.50 (The Tax) = $70

$70 Divided by $1.75 = 40 Yards

Answer:

50 grams

Step-by-step explanation:

Let the amount of cheese required by the recipe be "x"

Ann increased 60% from original amount and then used up 80 grams. Thus:

Original, increased by 60%, became 80

This translated to algebraic equation would be:

x + 0.6x = 80

Note: 60% = 60/100 = 0.6

So we can solve the above equation for "x" and get our answer. Shown below:

$x + 0.6x = 80\\1.6x=80\\x=\frac{80}{1.6}\\x=50$

Hence,

the recipe required 50 grams of cheese
