Answer:
0.625 days did the grass to grow 1 centimeters.
Step-by-step explanation:
Proportion states that two ratios or fractions are equal
The grass in Jamie yard grew 16 centimeters in 10 days. it growing at a constant rate.
We have to find how many days did the grass to grow 1 centimeters.
Let x be the days did the grass to grow 1 centimeters.
By definition of proportion:
By cross multiply we have;
Divide both sides by 16 we have;
x = 0.625 days
Therefore, 0.625 days did the grass to grow 1 centimeters.

Step-by-step explanation:
Hello,
At the beginning the population is 240,000
After 1 year the population will be
240,000*(1+7.75%)=240,000*1.0775
After n years the population will be
So after 7 years the population will be
So rounded to the nearest whole number gives 404,699
Hope this helps
A cube, is made off 6 squarial faces, so all faces on that cube, are squares, the front, back, left, right, top and bottom.
a square has all equal sides, and also all right angles, so all angles in a square are 90°. Let's say the sides are "x" long.
now, if we run a plane on that cube diagonally, check the picture below, the diagonal side at the bottom, by usin the 45-45-90 rule as you see it there, will be x√2.
let's keep in mind that, "x" is opposite side of that angle θ, and then x√2 will be the adjacent side of it.
and we can use those two to get the tangent and then the inverse tangent to get the value, as you see it in the picture.
if you need the angle in radians, run the inverse tangent again, just make sure your calculator is in radians mode.
