Answer:
423
Step-by-step explanation:
349+74=423
Answer:
y=35x−9
Step-by-step explanation:
Step 1: Add -12x to both sides.
12x−20y+−12x=180+−12x
−20y=−12x+180
Step 2: Divide both sides by -20.
−20y−20=−12x+180−20
y=35x−9
The equation is : C=250t +125 where C is the cost and t represent the number of tickets purchased.
Step-by-step explanation:
Let the cost of premium seat ticket be C
Let the number of tickets a fan buys to be t
Then, presenting the information as ordered pairs of coordinates (x,y) will be;
Fan 1, (3,875)
Fan 2, (8,2125)
Plot the ordered pairs as coordinates on a graph tool, find the slope of the linear graph and equation in slope intercept form as;
m=Δy/Δx
m=2125-875/8-3
m=1250/5
m=250
Equation of the graph,
Δy/Δx=250
y-875/x-3 =250
y-875=250(x-3)
y-875=250x-750
y=250x-750+875
y=250x+125
C=250t +125 where C is the cost and t represent the number of tickets purchased

Step-by-step explanation:
A=2πr(r+h)
A=6.28×14mm(+29mm)
A=77.92(14mm+29mm)
A=77.92×43
A=3350.56 mm
