Answer: 4 gallons require 5 5/39 spoons of syrup
Step-by-step explanation:
The answer is 100 degrees Celsius.
Sin = opposite / hypotenuse
cos = adjacent / hypotenuse
using pythagoras theorem =
adjacent = 5^2-3^2
= 16
= square root 16
=4
cos x = 4/5
The question is basically asking<em> "What is 1¼ × 6?"</em>
There are multiple ways to arrive at a solution for this.
The first is to break the 1¼ into parts.
1¼ = 1 + ¼. When we multiply 1¼ by 6, that's equal to 1×6 + ¼×6.
1×6 = 6.
¼×6 = 6/4 = 1½.
6 + 1½ = 7½ hours
You could also put 1¼ as an improper fraction and then multiply.
1¼ = 1 + ¼.
1 = 4/4.
4/4 + 1/4 = 5/4.
5/4 × 6 = (5×6)/4 = 30/4.
30/4 = 15/2 = 7½ hours
Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft = 
3 ft = ( 3 * 12 ) in ⇒ 36 in
