Answer:
$367.38 is the cost to stain the entire deck.
Step-by-step explanation:
Here is what you need to know beforehand:
<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.
--------------------------------------------------------------------------------------------------------------
<u>First, find the area of the circle. Here is the formula:</u>
Area = 3.14 (Pi) x r²
Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m
So the formula will look like this:
Area = 3.14 x 6²
<u>Then, you just do the math:</u>
Area = 3.14 x 6²
Area = 3.14 x 36
Area = 113.04
The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>
Answer = 113.04 x 3.25
Answer = 367.38
$367.38 is the cost to stain the entire deck.
Answer:
-66+12 or -54
Step-by-step explanation:
To remove the parenthesis multiply the number outside of the parenthesis (in this case -6) to the numbers inside of the parenthesis (11, and -2).

A negative multiplied by a positive is a negative.

A negative multiplied by a negative is a positive.

Answer:
D
Step-by-step explanation:
12/6 is 2 and the the exponents when you are dividing you just subtract. so 9-3 = 6 which makes it x^6.
Answer:
3n/3 or 3n÷3
Step-by-step explanation:
since it says triple the quotient of a <u>number</u>, we can use the number n.
To find the quotient means to divide and it's going to be by that numer.....n....... trippled (3)
put them all together and you get 3n/3

Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 =
( multiply both sides by 9 )
k = 135
y =
← equation of variation
