Answer:5.8
Step-by-step explanation:
Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
=
![\left [\frac{r_{plunger}}{r_{piston}}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%7D%7Br_%7Bpiston%7D%7D%5Cright%20%5D)
=![\left [ \frac{2118}{63}\right ]^{0.5}](https://tex.z-dn.net/?f=%5Cleft%20%5B%20%5Cfrac%7B2118%7D%7B63%7D%5Cright%20%5D%5E%7B0.5%7D)
=5.798
Answer:
The perfect squares it lies between are 64 and 81
The answer is 6√2
And it lies between the numbers 8 and 9
Hope this helps.
Answer: Good thing you provided the image!
Working down the columns:
C base= 2
D base = 4
C height =3
D height = 2
C area = bh = 8
D area = bh = 8
Step-by-step explanation:
Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.
The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.
For C the base is the 2 boxes, and going up until you meet the other parallel side you can count 4 boxes.
I usually default to using the side which I can easily count boxes as the base and go from there.
Answer:
X = 90 degrees
Step-by-step explanation:
I kilometer is .62 miles
1/6.2= 60/X
Cross multiply
X= 37.2 miles
