Step-by-step explanation:
the ladder becomes your hypotenuse,the wall is the height,this forms a right angled triangle and the angle of elevation forms at the base,use sine which is opposite over hypotenuse to get your answer
Answer:
C. y = -x + 68
Step-by-step explanation:
First, remember that slope-intercept form is y = mx + b, where m = slope, b = y-intercept.
We know that the slope is negative. Unfortunately, all the answers have negative slopes, so we can't rule anything out.
Let's look at the y-intercept. It looks like it's around 60, a little higher; 68 and 65 are both good options. It's clearly not 55 or 100, so eliminate choices D and B.
Now let's look at the slopes - it looks like the slope is closer to than 2x. Check out the attached graph - pick points at random and check which graph seems to match them most often!
The answer you are looking for is 1/3.
First, you must look at the denominators of each fraction, to see if you can simply divide straight across. In this case, you cannot, which means you must multiply by the reciprocal or "flipped" number. Generally when you multiply by the reciprocal, you flip the number with the smaller denominator to multiply.
So, you have 4/3 * 3/12. You then multiply straight across (4 * 3)/(3 * 12), to get an answer of 12/36, which simplified (divided by 3/3) gives you a final answer of 1/3.
I hope this helps!
One cylinder has two bases and one side, and the side is a rectangle.
So S = 2*base + side
S = 2* (pi*27^2) + (2*pi*27*37) = 3456pi
Answer:
40 cents.
Step-by-step explanation:
If he has enough money to buy 6 markers ate $3 for 6 then he must have 30/6 * 3
= $15.
So 30 pencils cost 15 - 3 = $12.
Each pencil costs 12/30
= $0.4
= 40 cents.
