Answer:
12:176 or 12/176
Step-by-step explanation:
Multiply both the top and bottom by 2.
6/88. 6 x 2= 12. 88 x 2= 176
So, 6:88 = 12:176 because you multiplied both numbers by 2.
6/88 x 2/2 = 12/176
Answer:
There are approximately 88 adults.
Step-by-step explanation:
The question is:
A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults
.
Solution:
Total number of people attending the fair is, <em>N</em> = 350.
The proportion of adults is: P (Adults) = <em>p</em> = 0.25.
Compute the number of adults in the fair as follows:


Thus, there are approximately 88 adults.
You can spot a linear equation when the highest degree for a variable in the equation is 1.
E.g.
y = 2x +4
The highest power of x in this equation is 1, since variable x of the 2x is x is to the power of 1, and 4 is a constant where you can imagine it to have an x but to the power of 0.
E.g.
y=x^2 + 2x +4
In this case, this would be an quadratic equation because the highest power that the variable x has in this equation is 2 (x to the power of 2).
Answer:
Part a) 
Part b) 
Step-by-step explanation:
we know that
The original area of rectangle is equal to

so
if the length is increased by 6% and the width is by 15%
then
the new area is equal to
![A=[1.06(14)][1.15(9.5)]\ cm^{2}](https://tex.z-dn.net/?f=A%3D%5B1.06%2814%29%5D%5B1.15%289.5%29%5D%5C%20cm%5E%7B2%7D)


The new area is (1.219) times the original area
Part a) Calculate the percentage change in area of the rectangle

convert to percentage

Part b) what is the original area as a percentage of the increased area of the rectangle?
Divide the original area by the increased area

Convert to percentage
