Answer:
Required two variable relation is 45x =y
Step-by-step explanation:
Speed of isabella car is v = 45 miles per hour
now, According to question she takes Y miles( = distance) in X hours (= time)
from The relation of velocity i.e.
velocity = 
on substituting the values in the above relation we get,
v = 45 = 
on further rearranging of terms we get,
= y
HENCE, required relation is 45x =y , which is a two variable equation.
There's on 38000 there? is it meant to be 380000?
Answer:
x = ~8.9
Step-by-step explanation:
a^2 + b^2 = c^2
c is the long side
a and b are the other two shorter sides
this means
x^2 + 19^2 = 21^2
x^2 + 361 = 441
x^2 = 441- 361
x^2 = 441- 361
x^2 = 80
square root of 80 = ~8.9
x = ~8.9
90^2+120^2=c^2
180+240=c^2
420=c^2
2 radical 105
So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.
The area of the rug is 354.34 square inches.
