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
In order to compute the mean, simply divide the sum over the number of
element in the sample, like this:
1)
2)
600000000+2000000+50000+100+20+3
With the rule of three
100% = 29.85
6% = ? So. (6 times 29.85)÷100= 1.79
29.85 + 1.79 = 31.64
100% = 31.64
15% = ? Soooooo. (15(31.64)) ÷ 100 =
First combine like terms 3x-x=14-5 then solve it yourself from here on
