Answer:
dimensions are 51x91
Step-by-step explanation:
Assuming that the gym is rectangular in shape, then...
l*w=4641
and 2l+2w=284
We have two variables and two equations so to solve this we plug one equation into another.
Solve for one variable:
l*w=4641
w=4641/l
Plug into the other equation...
2l+2(4641/l)=284
Solve
l*(2l+9282/l)=284
2l^2+9282=284l
2l^2-284l+9282=0
Factor the trinomial:
2(l−51)(l−91)=0
l−51=0 or l−91=0(Set factors equal to 0)
l=51 or l=91
now, lets plug it into one of the equations to find w
51*w=4641
w=91, l=51
or...
91*w=4641
w=51, l=91
Answer:
3 19/24
Step-by-step explanation:
![\frac{3}{8} + \frac{2}{3} + \frac{11}{4} = \frac{9 + 16 + 66}{24} = \frac{91}{24} = 3 \frac{19}{24 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B8%7D%20%20%2B%20%20%5Cfrac%7B2%7D%7B3%7D%20%20%2B%20%20%5Cfrac%7B11%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B9%20%2B%2016%20%2B%2066%7D%7B24%7D%20%20%3D%20%20%5Cfrac%7B91%7D%7B24%7D%20%20%3D%203%20%5Cfrac%7B19%7D%7B24%20%7D%20)

Answers:
A: 29 times
B: Yes
Explanations:
A: You do 35/1.25 and get 28, but thats not a better deal that's the same, so you go up one and make it 29.
B: Yes, 45(1.25) is 56.25 which is well over 35
the answer for this question is ( d)
