You can find the simplest form of 120/180 by rounding down the numbers. you can take the zeros away and your left with 12/18. you can make it even smaller by using the 6 time tables. 12 and 18 are both in the 6 time tables. 2×6=12 and 3×6=18. The answer is 2/3.
Hope I helped :D
Answer:
Step-by-step explanation:
There is a relationship between lines that are perpendicular. Their slopes are negative reciprocals of each other. Example: if one line has a slope of 4/3 then a line with the slope of -3/4 is perpendicular to it (they intersect at right angles).
So to find the slope of a line perpendicular to y = -2/3x + 4 we must know the slope of it. The slope, when the line is in the slope-intercept form (aka y = mx + b), is the multiplier in front of the "x" so in this case it is -2/3. So a line perpendicular to it has a slope of 3/2.
Now that we know the slope (m = 3/2) we can find the equation of the line that has a slope of 3/2 but goes through the point (-2, -2) in a couple of ways.
1) Use the slope-intercept form of a line and plug in the values of x = -2 and y = -2 (from the point (-2, -2) like this:
y = mx + b
y = 3/2x + b
-2 = 3/2(-2) + b
-2 = -3 + b
1 = b
So y = 3/2x + 1
2) We can use the point-slope equation y - y1 = m(x - x1) which works great if you know the value of m (we do, m = 3/2) and some point (x1, y1) on the line (and we do, (-2, -2); so x1 = -2 and y1 = -2):
y - y1 = m(x - x1)
y - y1 = 3/2(x - x1)
y - (-2) = 3/2(x - (-2))
y + 2 = 3/2(x + 2)
Although it looks different than the other equation, it is really the same. Just distribute and combine like-terms and you'll see it's the same. So either is an acceptable answer for this quest
When determining the probability that a coin lands on the head more than once, it is first important to know that every time you flip the coin, it has a 50% chance to land head’s up and 50% chance to land tail’s up. The combinations you can get with 4 flips are HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTTT, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, TTTT. As you can see, there are 16 possible outcomes and 11 of them have head’s coming up more than once. The chances of head’s coming more than once with four tosses of a coin is 68.75% (11/16 times 100)
Answer:
$240
Step-by-step explanation:
Because 6% of 800 are 48, and 48 x 5 it's 240
