Answer:
10 km/h
Step-by-step explanation:
I'm not really sure about this but no ones answering your question and I wanna help.
So basically to calculate the average speed you need to divide the distance travelled by time taken
But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km
Now that we have the time and distance all we have to do is find the average speed.
Average Speed = distance ÷ time
So 150 ÷ 15 = 10 km/h
Answer:
The graph in the attached figure N 2
Step-by-step explanation:
The complete question in the attached figure N 1
we have the ordered pairs
(-4,9),(-1,3),(0,1),(2,-3)
Using a graphing tool
Plot the given ordered pairs in the coordinate plane
Remember that
In a ordered pair (x,y), the first coordinate is the location of the point in the x-axis and the second coordinate is the location of the point in the y-axis
see the attached figure
The graph represent a line
<em>Find the equation of the line</em>
<em>Find the slope</em>
take two points

The equation of the line in slope intercept form is equal to

we have

substitute

For this case we must find 35% of 280.
Kerrie gets 10% and then 25%. So:
10% of 280:
280 ------------> 100%
x -----------------> 10%
Where "x" represents the amount given by 10% of 280.

Thus, 10% of 280 is 28.
Now, we find 25% of 280:
280 ------------> 100%
x -----------------> 25%
Where "x" represents the amount given by 25% of 280.

Thus, 25% of 280 is 70.
So we have that 35% of 280 is given by:

So, Kerrie's solution is correct.
Answer:
Option A
Answer:
4k^3 - k^2 - 2k
Step-by-step explanation:
-k * -4k^2 = 4k^3
-k * k = -k^2
-k * 2 = -2k
4k^3 - k^2 - 2k
1) number of cards that aren't : number of cards that are 3
we have 48 cards that arent 3 and 4 cards that are. that means that odds are:
12:1 of not drawing 3
2) fallow same logic. its just opposite.
1:12
3) same logic. but there are only 2 black 7 cards which means that odds are:
50:2 or
25:1
4) opposite of previous.
1:25
