Step-by-step explanation:

when you divide by a fraction you just multiply by its reciprocal

\frac{2}{3} ÷ \frac{1}{3} = \frac{2}{3} * \frac{3}{1}

then just solve

\frac{6}{3}=2

<em>for the second one do the same thing</em>

<em />\frac{4}{5} * \frac{2}{1} =\frac{8}{5}<em />

Answer:

  cos(45°) = (√2)/2

Step-by-step explanation:

The cosine of 45° is the x-coordinate of the point on the unit circle where the line y=x intersects it. That is, it is the positive solution to the equation ...

  x^2 +x^2 = 1

  x^2 = 1/2 = 2/4 . . . . . collect terms, divide by 2, express the fraction with a square denominator

  x = √(2/4) . . . . . . take the square root

  x = (√2)/2 . . . . . simplify

The cosine of 45° is (√2)/2.

A plant is already 52 centimeters tall, and it will grow one centimeter every month. Let H be the plant's health (in centimeters
Tasya [4]

Plant's height after 31 months:82 centimeters

<h3>How to find the height of the plant</h3>

The equation that can be used to find the height of the plant is given as

h = 52 centimeters + 1m

We have that the plant grows at 1 centimeter every month hence we have 1m in the equation.

Then the number of periods is m, Now we are to find the height in this period of time

h = 52 + 1*31

= 51 + 31

= 82

Hence the height after 31 months is given as 82 centimeters.
