Answer:

6,280 ft³

Step-by-step explanation:

To find lateral surface area, use the formula L = 2 $\pi$ rh, then plug in the values:

L = 2(3.14)(25)(80)

L = 12,560 ft³

Since its a half cylinder, we have to divide this by 2:

12,560/2 = 6,280

So, the lateral area of the roof is 6,280 ft³

Abbi has $400 in $5 bills. If she has 38 bills, how many of them are $20?

Sergio039 [100]

F=5 dollar bills
t=twent dollar bills

38 total bills
f+t=38

400 in bills
400=5f+20t

we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation

-5f-5t=-190
5f+20t=400 +
0f+15t=210

15t=210

divide both sides by 15
t=14

subsitute
t+f=38
15+f=38
f=23

23 five dolar bills
15 twenty dollar bills

A line is defined by the equation 2x+y -4. Which shows the graph of this line?

Nitella [24]

Answer:

Not sure if you mean 2x+y=-4 or 2x+y=4

either way put it in y=mx + b form (slope intercept)

Step-by-step explanation:

so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis

so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
