A rectangle has a length of 72 cm and a width of 56 cm. A second rectangle has the same area as this one, but its width is 21 cm
Anastaziya [24]

Answer:

192

Step-by-step explanation:

Well if the first rectangle is 72 and 56, then we can find the area of that by multiplying length times width which would be 4032, so that would be the area of the second one. then we divide 4032 by 21, which is 192.

P.S, This is my first question answered, so if im wrong please let me know, thank you!

An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ
pshichka [43]
I found a missing question online. <span>What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
</span>A: \theta(0)=a\\&#10;B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c
<span>Our angular displacement is:
</span>\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad<span>

18x - 77=1<br> X - 7y=-33
SIZIF [17.4K]

Answer:

x=-33+7y

then putting value of x

18(-33+7y)-77=1

-594+126y-77=1

-671+126y=1

126y=670

y=670/126

I appreciate any help. Trying to get the hang of these.
aliya0001 [1]

Answer:

x = 12

Step-by-step explanation:

Since the top line is equal to the bottom, you make the equation -

x + x + 4 = x + 16

You subtract an x on both sides because there is one on each side -

x + 4 = 16

Then you subtract the 4 from both sides to get x by its self, which makes

x = 12
