Ratio = 1:3
or in other words = sale price:original price
Therefore, it'd look like this = sale price:$81
So to work out the original price, you'd do $81 divided by 3 (81 ÷ 3 = $27).
The sale price is $27..
With questions like these, I like to use a system of operations my teacher told me.
First, we have to identify what the question is asking us to find. The question is asking us to find how many bouquets a florist makes per day (which is in one day).
Then, we have to find information that will help us answer the question. She makes 215 bouquets is 5 days.
Now, you put it together!
If she makes 215 bouquets in 5 days, and we need to find out how many she makes in 1 day, we need to divide 215 by 5!
215 / 5 = 43.
The florist makes 43 bouquets per day!
The answer to this equation is 48.
Given: m ∠3 = m ∠4
To Prove: ∠1, ∠2 are supplementary .
Proof : m ∠3 = m ∠4 ( Given) ------------(1)
m<2 + m< 3 = 180 degrees ( <2 and <3 form a linear pair). ----------(2)
m< 4 = m<1 (Vertical angles are equal) -----------(3).
Substituting, m<4 =m<1 in (1), we get
m ∠3 = m ∠1.
Now, substituting m ∠3 = m ∠1 in (2), we get
m<2 + m< 1 = 180 degrees.
Sum of m <1 and m<2 is 180 degrees.
Therefore,<em> ∠1, ∠2 are supplementary by the defination of supplementary angles.</em>
The square root of 16 is 4
