54m=P 170=A
x+y=54, y=54-x
x*y=170, y=170/x
54-x=170/x
54x-x^2-170=0
x^2-54x+170=0
x= (54(+/-)root2916-680)/2
x=27(+/-)root559
x+y=3.35+50.65=54
x*y=3.35*50.65=170m
Dimensions are 3.35m and 50.65m
Answer:
A unit rate is a rate where the second quantity is one unit , such as $34 per pound, 25 miles per hour, 15 Indian Rupees per Brazilian Real, etc.
Step-by-step explanation:
how do you not know what are unit rates
You would subtract the the amount painted from 500.
500-193=307
They have to paint 307 more.
Answer:
Step-by-step explanation:
Number of side = n = 7
Sum of interior angles of 'n' sided polygon = (n - 2) *180
= (7 - 2)* 180
= 5 * 180
= 900
x + 150 + x -20 + 140 + 120 + x + 20 + 130 = 900
Combine like terms
x +x +x + 150 - 20 + 140 + 120 + 20 +130 = 900
3x + 540 = 900 {Subtract 540 from both sides}
3x = 900 - 540
3x = 360 {Divide both sides by 3}
x = 360/3
x = 120
Interior angle Exterior angle
∠A = 120 180 - 120 = 60
∠B = 130 180 - 130 = 50
∠C = 120 + 20 = 140 180 - 140 = 40
∠D = 120 180 - 120 = 60
∠E = 140 180 - 140 = 40
∠F = 120 - 20 = 100 180 -100 = 80
∠G = 150 180 - 150 = 30
