Answer:
Step-by-step explanation:
To figure out the unit rate, divide 5.12 by 128. You should get 0.04, which is the unit rate or cost per ounce. To figure out how much the 96 oz can should be, multiply $0.04 times 96.
Your answer should be $3.84.
Given:
Total length of tape in roll = 16.8 meters
Length of each piece = 1.125 meters
Number of pieces = 8
To find:
The remaining tape.
Solution:
We have,
Length of 1 piece = 1.125 meters
Length of 8 piece = 8 × 1.125 meters
= 9 meters
Total length of tape in roll = 16.8 meters
Remaining tape = Total length of tape in roll - Length of 8 piece
= 16.8 - 9 meters
= 7.8 meters
Therefore, the length of remaining tape is 7.8 meters.
so it's obvious, I guess :)
Now, let's prove is not rational number.
Proof by contradiction.
Let assume is a rational number. Therefore it can be expressed as a fraction where and .
is an even number, so must also be an even number, and therefore also must be an even number. So, we can say that , where .
Since is an even number, then also must be an even number. 3 is odd, so for to be an even number, must be an even number, and therefore is an even number.
But if both a and b are even numbers, then it contradicts our earlier assumption that . Therefore is not a rational number.
Whats your question bro? whats the number? the number is
Answer:
59%
Step-by-step explanation:
Which continent is estimated to have more than 5.31 billion people by 2050? To solve, find what percent 5.31 billion is of 9 billion. Write a ratio of part to whole. ? 100= 5.31 9Solve for ?. Change your answer for ? 100to a decimal and then to a percent.________ %
This is calculated as:
5.31 billion/9 billion × 100
= 0.59 × 100
= 59%
