Answer:
length of rectangle=16 inches
width of rectangle=10.5 inches
Step-by-step explanation:
given ,perimeter of rectangle=53 inches
let ,length of rectangle= l=2b-5
width of rectangle=b
p=2(l+b)
53=2(2b-5+b)
26.5=3b-5
31.5=3b
b=
b=10.5 inches
l=21-5=16 inches
That first one is correct there is no solution since they are parallel.
Answer:
Y doesn't vary directly with x
Answer:
y = 189.8
Step-by-step explanation:
Apply trigonometric function to find y.
Reference angle (θ) = 50°
Adjacent side = 122
Hypotenuse = y
Apply CAH, since the Hypotenuse and the Adjacent are involved.
Thus:
Cos θ = Adj/Hypo
Plug in the values
Cos 50° = 122/y
y*Cos 50° = 122
y = 122/cos 50°
y = 189.8 (beater tenth)
I would take 84 times 3 for the three tests which gives you 252. I would then subtract the two test they took which is the 90 and 82 for a total of 172. 252-172 =80. The lowest score would be an 80
