A rectangle has two couples of equal sides, so a soccer fields has two 80-meters sides and two 120-meters sides.
This leads to a perimeter of
If you go around it twice, you'll run 800 meters
1/5(x-2)=1/10(x+6)
Distribute and multiply first
(1/5*x) -(1/5*2)=(1/10*x) +(1/10*6)
1/5x-2/5=1/10x+6/10
We do not have the same denominators on both sides. 5 goes into 10 two times so we will multiply everything on the left by 2 to get a common denominator.
2/10x-4/10=1/10x+6/10
Subtract 1/10x from both sides
1/10x-4/10=6/10
Add 4/10 to both sides
1/10x=10/10
1/10x= 1
Multiply both sides by 10/1 (the fraction inverse) to get rid of the fraction.
(10/1)(1/10x) =(1)(10/1)
x= 10
Check work:
1/5(x-2)=1/10(x+6)
Substitute your answer for x
1/5(10-2)=1/10(10+6)
1/5(8)=1/10(16)
8/5=16/10
Simplify 16/10 by dividing by 2
8/5=8/5
Hope this helps!! :)
Answer:
The margin of error associated with this confidence interval is 20
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. The interval is symmetric, which means that the margin of error is the difference between these two bounds(upper - lower), divided by 2.
In this problem, we have that:
Lower bound: 520
Upper bound: 560
Determine the margin of error associated with this confidence interval.
(560 - 520)/2 = 20
The margin of error associated with this confidence interval is 20
Answer:
-5 homie
Step-by-step explanation:
-5 times 2 is -10
Answer:
98.88 ft^2 to nearest hundredth
Step-by-step explanation:
Area of slice = (37/360) * pi * 17.5^2 ( 17.5 = radius ( half diameter of 35))
= 98.88 ft^2
