We know that
if the dilated circle <span>passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=</span>√[(4-0)²+0²]-----> d=√16------> d=4 units
the new radius is 4 units
original radius is 1 units
[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4
the answer is
<span>the scale factor of dilation is 4</span>
Answer:
It is mainly used while doing scientific notation. If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100.A quarter is 0.25 dollars so the ratio between 1 dollar and a quarter is 1/0.25(it means the dollar and the quarter which is 0.25 dollars) and that equals =4
Answer:
<u>870</u> people attend the school.
Step-by-step explanation:
Given:
Thad conducted a survey on hair color at his school.
His results were:
23 students had blonde hair, 38 students had black hair, 7 students had red hair and 19 students had brown hair.
Now, to find number of people attended school if he had sampled 1 out of every 10 students.
So, we add the total number of students who had been surveyed on hair color:
Then, we get the percentage of the sample of 1 out of 10 students:
<u><em>Thus, we get that 10% of students surveyed from the total who attend the school.</em></u>
Now, to get the number of people who attend school we set an equation:
Let the people attend the school be 
.
So, 
⇒ 
⇒ 
<em>Multiplying both sides by 100 we get:</em>
⇒ 
<em>Dividing both sides by 10 we get:</em>
⇒ 
Therefore, 870 people attend the school.
The net sales is $46,0000
<h3>What is Gross sales?</h3>
Gross Sale is the total of goods sold to the customers during a period. The goods can be sold on a cash basis or an account basis. The net sale is calculated as the gross sales minus sales returns and allowances and discounts on the sale.
Given:
sales= $50,000
sales returns = $4000
Now,
Net Sale = Gross Sale - Sales returns and allowances
= $50,000 - $4,000
= $46,000
Hence, the net sales is $46,000
