Answer:
Jamarion can run 4 miles in 30 minutes. What is his speed in miles per hour?
So we should first start off by checking for the ones with the same area, which is 72sq cm
80×90=7200sq cm so A is incorrect
8×10=80sq cm so B is incorrect
3×24=72sq cm so, so far C is correct
4×14=56sq cm so D is incorrect
And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter
24+24=48
48+3=51
51+3= 54
So the perimeter is different, making C the correct answer
For a line in the form:
In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:
Now, two lines are perpendiculars if the slopes satisfy the following equation:
So, for the line we want the slope is:
Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:
The equation of the line is y = 5x - 7
Answer:
R=-4
Step-by-step explanation:
-3(2r+7)=3
-6r-21=3
-6r=24
r=-4
I hope this is correct and have a great day
Only <span>first and second place runners:
</span>11*10=110 ways
Hope that helped.
