Answer:
6 6/7 km/h
Step-by-step explanation:
The relations between speed, time, and distance are ...
time = distance/speed
speed = distance/time
__
So, to find the average speed, we need to know the total distance and the total time. The distances are given, but we need to compute the times.
time jogging = (2 km)/(8 km/h) = 1/4 h
time walking = (2 km)/(6 km/h) = 1/3 h
Then the woman's average speed is ...
average speed = (total distance)/(total time) = (2 km + 2 km)/(1/4 h + 1/3 h)
= (4 km)/(7/12 h) = 48/7 km/h
= 6 6/7 km/h
Answer:
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14
Answer:
Step-by-step explanation:
The rule for the translation is given as
The coordinates of F are (2,2).
We substitute these coordinates into the translation rule to find the coordinates of F'.
This is the hardest question I've answered all day.
One way to find a sub-total is by *simply* adding everything together, and a example would be below, buy yeah, you just add everything together.
For example:
Cookies (item # 594993) $2.98
Cake (item # 4354533) $4.50
Vans low tops (item # 594939) $60.00
Vans socks (item # 598993) $15.00
And just by adding all this, that how you would find the subtotal. Hope this helps! ;)
Answer:
A( multiply both sides by 6)
As seen , the L.C.M is 6 so to do away with the fractional form, we will multiply by 6
