150/2000 cause 2000 would be your bottom number and 150 is your is your top number
Answer:
The required value of x is 12 units.
Step-by-step explanation:
Given that the figure A is a scale image of figure B.
We are to find the value of x.
Since figure A is the scale image of figure B, so both the figures are similar to each other.
Also, the corresponding sides of the similar figures are proportional, so we get
Thus, the required value of x is 12 units.
Answer:
The surface area of Design A is smaller than the surface area of Design B.
The area of Design A is 94.65% of the Design B.
Step-by-step explanation:
The area of a right cone is given by the sum of the circle area of the base and the lateral area:
(1)
Where:
r: is the radius
L: is the slant height
The slant height is related to the height and to the radius by Pitagoras:
(2)
By entering equation (2) into (1) we have:
Now, let's find the area of the two cases.
Design A: height that is double the diameter of the base, H= 2D = 4r
The volume of the cone is:

We can find "r":

The area is:
Design B: height that is triple the diameter of the base, H = 3D = 6r
The radius is:
The area is:
Hence, the surface area of Design A is smaller than the surface area of Design B.
The percent of the surface area of Design A is less than Design B by:

Therefore, the area of Design A is 94.65% of the Design B.
