By making the surface rougher and to increase the force pushing the surfaces together.
Answer:
900 ft!
Step-by-step explanation:
Volume = l ∗ w ∗ h
50-(30.8+4.9)=14.3 kg.
You start with 50 then you need to subtract 30.8 and 4.9 from it. So you add them together and get 35.7. Then you subract 25.9 from 50 and get 14.3 kg.
Answer:
300 minutes
2:00 p.m
Step-by-step explanation:
Given the following:
Time taken to mark a script :
Mrs Kanja = 5mins
Miss Kanene = 4mins
Mrs Nyaga = 12 mins
Number of scripts = 160
Start time = 9:00 a.m
Rate at which each of them mark:
Mrs Kanja = t / 5
Miss Kanene = t/4
Mrs Nyaga = t/12
Combined rate :
t/5 + t/4 + t/12 = 160
(12t + 15t + 5t) / 60 = 160
32t / 60 = 160
32t = 160 * 60
32t = 9600
t = 9600 / 32
t = 300 minutes
300 minutes = 300/60 = 5hrs
9:00 a.m + 5 hours = 2:00 p.m
Answer:
Step-by-step explanation:
You use the given information in the standard form of a circle equation to solve for r. We have (h, k) which is the center and a point (x, y). The standard equation for a circle is
Filling in:
and
and
Now that we used the coordinate we don't need it anymore. x and y go back into the equation as x and y, not numbers. We do, however, need the center. Writing the equation:
which is choice D.
