Answer:
46.25%
Step-by-step explanation:
First, add both numbers together. (86 + 74).
Next, we have 160. And that is 100%.
Now, we have to find what 74 is compared to 160.
74 is 46.25% of 160.
There's our answer.
Answer:
See Below.
Step-by-step explanation:
Problem 1)
We want to simplify:
First, let's factor the denominators of each term. For the second term, we can use the difference of two squares. Hence:
Now, create a common denominator. To do this, we can multiply the first term by (<em>a</em> + 1) and the second term by (<em>a</em> + 2). Hence:
Add the fractions:
Factor:
Simplify:
We can expand. Therefore:
Problem 2)
We want to simplify:
Again, let's create a common denominator. First, let's factor out a negative from the second term:
Now to create a common denominator, we can multiply the first term by (<em>a</em> - <em>c</em>) and the second term by (<em>a</em> - <em>b</em>). Hence:
Subtract the fractions:
Distribute and simplify:
Cancel. Hence:
Translate that into an equation, and we get:
a+b = 24
a-b = 15
If we add these two equations, we get:
2a = 39
a = 39/2 = 19.5
Plug back in a = 19.5 and solve for b
a + b = 24
19.5 + b = 24
b = 4.5
The two numbers are 19.5 and 4.5.

Answer:
35
Step-by-step explanation:
First, we will define range.
The difference between the highest and lowest values in a data is called range. To find the range, first the highest and lowest values are found from data, then the lowest value is subtracted from the highest value.
In the above data,
Highest Value=71
Lowest Value=36
Range=Highest value-lowest value
=71-36
=35
