Answer:
4/15
Step-by-step explanation:
to find out the portion that is shaded we can do the following:
1 - (1/3 + 2/5)
now we want a common denominator, we can use 15:
15/15 - (5/15 + 6/15) → 15/15 - 11/15
the answer is 4/15
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:
D
Step-by-step explanation:
To solve both of these expressions, we want to add or subtract from left to right.
For the first one, we can rewrite it as:
8-6-9
=2-9
=-7
The second one we can rewrite as:
5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11
