Answer: The 3 in 3,899 is 10 times the 3 in 4,385!
35 necklaces multiplied by 4 weeks is 140. Multiply 140 by 15, representing the amount of money each necklace costs and you get 2,100. That is the total amount sold, but because the 6 costumers brought their necklaces back, you have to take 6 times 15 to see how much the total returned necklaces cost. That would be $210, so you take $2,100 and subtract $210, and your answer is $1,180. That is the final answer.

You have a right triangle therefore you can calculate the base as (9tan30)=sqrtof3 over 3
Area of triangle 1/2 bh = 1/2(sqrt3 over 3)
(9) As this is just 1 triangle you then need to multiply it by 2
bh = sqrt of 3 over 3 * 9</span><span>

Answer:
<h2>
</h2>
Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>
</h3>
where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>
</h3>
So the formula for the variation is
<h3>
</h3>
From the question
when x = 4
<h3>
</h3>
Hope this helps you
