Answer:
12 milk chocolates.
Step-by-step explanation:
-We know that probabilities add upto 1:
Let X be the total number of chocolates. We know that probability is the successful events divided by the total number of events:
#We subtract the number of dark chocolates from X to get the number of milk chocolates:
Hence, there must be 12 milk chocolates.
It’s the first one.
the one with 9 squares with 2 filled in
now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.
namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°. Thus cos(1140°) = cos(60°).
what's that cosine of 60°? Check the picture below.
Answer:
Bumby Avenue is represented by the line:
y = -4*x - 7.
Primrose Avenue can be represented with:
8x + 2y = 17.
We may want to find the point where both avenues intersect.
Let's isolate y in this second equation:
2y = 17 - 8x
y = 17/2 - 8x/2 = -4*x + 17/2
Now we can see that the equation for Primrose Avenue has the same slope than the equation for Bumby Avenue, and when two linear equations have the same slope, means that the lines are parallel.
Then we can conclude that Primrose Avenue and Bumby Avenue are parallel, so they never meet eachother.
<em>capacity = 140 liters</em>
- Step-by-step explanation:
<em>1 h = 60 min</em>
<em />
<em>60 min ................ 240 l</em>
<em>35 min ...................... x l</em>
<em>x =35×240/60 = 8400/60 = 140 liters</em>
