The actual dimension of the sail are 6 m tall and 4.5 m wide.
The model is 20 cm tall. First we need to find the ratio which Kendall used in his model.
6 meters of actual length is represented in model by 20 cm.
6 meters of actual length is represented in the model by 0.2 m.
1 meter of actual length is represented in the model by 0.2/6 = 1/30 meters
So, the ratio of actual measure to model measure will be:
1 : 1/30
or
30 : 1
The actual width of the sail = 4.5 meters
The width of the sail in the model will be = 4.5 x 1/30 = 0.15 m = 15cm
So, the dimensions of the sail in the model will be 20 cm tall and 15 cm wide.
Answer:
Step-by-step explanation:
X = premium seats
y = regular seats
You need two equations: (x + y - 10 = 1200) and (30x + 20y = 30,180)
1.) Isolate one variable
y = 1,210 - x
2.) Plug the new equation into the second ORIGINAL equation
30x +20(1,210 - x) = 30,180
3.) Ditribute
30x + 24,200 - 20x = 30,180
4.) Add like terms
10x + 24,200 = 30,180
5.) Subtract 24,000 from either side
10x = 6,180
6.) Solve for x
x = 618
7.) Plug in x to the equation of your choosing
618 + y - 10 = 1200
8.) Solve for y
608 + y = 1,200
y = 592
The theater sold 592 regular seats and 618 premium seats.
Answer:
3=-1/2(-2)+b
solve
3=1+b
2=b
b=2
now that we have the slope and y intercept of the equation construct your equation:
y=-1/2x+2
Neither of these answers are correct. I graphed them all and not a single one passed through (-2, 3)
Additionally, the slopes of B and D are inncorrect and lines A and C dont pass through the point (-2, 3) the only correct equation is y=-1/2x+2
I graphed it and it was valid
Maybe ask your teacher if there were any mistakes?
