A sunflower was 20 1/2 inches tall. Over the next 6 months, it grew to a height of 37 inches tall. What was the average yearly g

guajiro [1.7K]

Answer:

33 inches per year

Step-by-step explanation:

In half a year, the sunflower grew 37 -20 1/2 = 16 1/2 inches. Your proportion is ...

(16 1/2 inches)/(1/2 year) = g/(1 year) . . . . . . . where g is the yearly growth

Multiplying by 1 year and simplifying, you can find g to be

g = (33/2 inches)/(1/2) = 33 inches

That is, the growth rate is 33 inches per year.

<em>Comment on the solution technique</em>

I personally find a proportion to be unnecessary. When you want to find the rate of x per y, divide the amount of x you are given by the amount of y you are given.

Here, you are given a growth of 16 1/2 inches in 1/2 year, so you simply perform the division (16 1/2 inches)/(1/2 year) = 33 inches/year.

This graph shows the solution to which inequality

Butoxors [25]

Answer:

A) $y > \frac{2x}{3} +1$

Step-by-step explanation:

The general form of a straight line is y = mx + c, where m is the slope and c is the y-intercept.

From the graph, we have the end points of the line as (3,3) and (-3, -1).

Using these points, we will find the value of the slope 'm'.

i.e. m = $\frac{-1-3}{-3-3}$

i.e. m = $\frac{2}{3}$

So, we get the equation of the line as $y = \frac{2x}{3} +c$ .

Now, using any point say (3,3) and the above equation, we will find the value of the y-intercept c.

i.e. $3 = \frac{2*3}{3} +c$ .

i.e. c = 1.

Hence, the equation of this straight line is $y = \frac{2x}{3} +1$ .

As seen from the graph, the line corresponding this straight line is dotted not solid, this means that the equality sign is not possible. So, we are left with either A or B.

To get the final answer, we will use the 'Origin Test' i.e. substitute the point (0,0) on both A and B. Then,

1. If the inequality is satisfied, the shaded region is towards the origin.

2. If the inequality is not satisfied, the shaded region is drawn away from the origin.

Now in option A, the 'Origin test' fails and the equation is not satisfied and therefore its graph will be drawn away from the origin, which is the case in our problem.

Hence, option A is correct.

Answer:

25/36

Step-by-step explanation:

The dicisors of 12 on a die are 1,2,3,4,6

So 5/6 per die

5/6*5/6 = 25/36
