Answer: A. A=(1000-2w)*w B. 250 feet
C. 125 000 square feet
Step-by-step explanation:
The area of rectangular is A=l*w (1)
From another hand the length of the fence is 2*w+l=1000 (2)
L is not multiplied by 2, because the opposite side of the l is the barn,- we don't need in fence on that side.
Express l from (2):
l=1000-2w
Substitude l in (1) by 1000-2w
A=(1000-2w)*w (3) ( Part A. is done !)
Part B.
To find the width w (Wmax) that corresponds to max of area A we have to dind the roots of equation (1000-2w)w=0 ( we get it from (3))
w1=0 1000-2*w2=0
w2=500
Wmax= (w1+w2)/2=(0+500)/2=250 feet
The width that maximize area A is Wmax=250 feet
Part C. Using (3) and the value of Wmax=250 we can write the following:
A(Wmax)=250*(1000-2*250)=250*500=125 000 square feets
Answer:
Hi there!
Your answer is:
It will take 2.2 months for both gyms to be the same amount of money!
Step-by-step explanation:
Fitness 19:
39+ 17x
Anytime Fitness:
50+ 12x
Put them equal to each other:
39+17x = 50+12x
-12x
39+5x = 50
-39
5x = 11
/5
x= 2.2 months
39+17(2.2)= 76.4$
50+12(2.2)= 76.4$
Hope this helps!

Answer:
1.311
Step-by-step explanation:
That multiplier is the product of the multipliers for each of the increases:
(1 +15%)(1 +14%) = 1.15×1.14 = 1.311
Answer: um i think you asked the question wrong. But ok.
Step-by-step explanation:
= 47 miles per hour
This is a fraction equal to
47 miles ÷ 1 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
47 miles ÷ 1
1 hours ÷ 1
=
47 miles
1 hour
=
47 miles
hour
= 47 miles per hour
