well let's round. 90= 100, 75=80 that is how I face it. now 80 is 1/5 of 5/5= 100. so as a (%) we would sort it like:::: it is 80% out of +100 so he must have grown around 13%-16% due to him being 75kg in the past.
Answer:
The area of the second rectangle will be 36 square centimetres
Step-by-step explanation:
Given:
Area of the first rectangle = 4 square centimetres
A second rectangle is 3 times as long and 3 times as wide as the first rectangle
To Find:
Area of the second rectangle = ?
Solution:
We know that area of the rectangle is Length X breadth
Length X width = 4
In this case the are 2 possibilities
Case 1:
Length = 2 cm
Width = 2 cm
2 X 2 = 4
Now According to the question
Length is 3 times = 2 X 3 = 6cm
width is also 3 times = 2 X 3 = 6 cm
Now the area of the second rectangle will be
6 X 6 = 36 square centimetres
Case 2:
Length = 4 cm
Width = 1 cm
4 X 1 = 4
Now According to the question
Length is 3 times = 4 X 3 = 12 cm
width is also 3 times = 1 X 3 =3 cm
Now the area of the second rectangle will be
12 X 3 = 36 square centimetres
Answer:
Step-by-step explanation:
<u>Slope intercept form:</u>
<u>Use two points from the graph:</u>
<u>The first point is the y-intercept: </u>
<u>Find the slope using the slope formula:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-9 - (-8))/3 = -1/3
<u>The equation is:</u>
Answer:
d. both the slope and price elasticity of demand are equal to 0.
Step-by-step explanation:
In order to graph the demand curve, the quantity demanded is plotted along x-axis and the price is plotted along y-axis. An image attached below shows the horizontal demand curve.
Horizontal demand curve, as its name indicates, is a horizontal line which is parallel to x-axis. Since, the slope of any line parallel to x-axis is 0, we can conclude that the slope of Horizontal demand curve is 0.
A horizontal demand curve can be observed for a perfectly competitive market. Since, its a perfect competition, the price of a product by all competitors will be the same. In this case, if a firm decides to increase the price, he will loose his market share as no customer will buy the product at increased price. They will rather go with the other competitor who is offering a similar product at lower price.
On the other hand, if a competitor decides to lower his price in such case, he will experience loss. Therefore, the competitors do not have the option to change the price. Therefore, we can say the price elasticity of demand in this case is 0.
So, option D describes the horizontal demand curve correctly.
