You said there were 40 yellow carsso 40×9 is 360
Answer:
Step-by-step explanation:
2x-y=4 ..........(1)
x+y=5 ...........(2)
<u>Add equation 1 and 2:</u>
We get:
3x=9
x=9/3
x=3
Substitute value of x in (2):
x+y=5
3+y=5
y=5-3
y=2
(3,2)
This is my go at the problem.
Let x be the original price.
72/100=6/100 of x.
so,
x=72/100 ÷ 6/100= $12.00
The answer is $12.00
Hope this helps!
Answer:
Change in area=24
-48
Step-by-step explanation:
Let s will be the side of square and r will be the radius of circle.
Then two given conditions are
1)dr/dt=2 m/s
2)ds/dt=1 m/s
Area enclosed=(Area of square)-(Area of circle)
Area of square=
Area of circle=
Area enclosed=
dA/dt=2
r(dr/dt)-2s(ds/dt)
At s=24,and r=6
dA/dt=2(
)(6)(2)-2(24)(1)
Change in area=24
-48
