PLEASE HELP!!!

Answer/Step-by-step explanation:

Part A: Net A is the correct net. If we decide to fold the net, we'd get the shape of the prism. Folding back net B won't give us the shape of the prism because of the position and arrangement of the right triangular  bases.

Part B:

AB =  3in

BC = 5 in

CD = 9.4 in

Part C: surface area of the prism can be calculated by calculating the area of each part of the net, and summing them together as follows,

Area of the 2 triangular bases = 2(½*base*height of triangle) = 2(½*4*3) = 2*2*3 = 12 in²

Area of the three rectangles =

= (9.4*4) + (9.4*3) + (9.4*5) = 37.6 + 28.2 + 47 = 112.8 in^2

Surface area of prism = 12 + 112.8 = 124.8 in²

What is the measure of ∅?<br><br>A. 2.5 π radians<br>B. 2.5 radians<br>C. 4 radians<br>D. 5 radians​
natka813 [3]

Answer:

C. 4 radians

Step-by-step explanation:

20=\frac{\pi (Ctrl.Angle)(5)}{180}

Ctrl Angle = ∅

∅ = \frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }

in radians:

∅ = \frac{720}{180} =4

Hope this helps

Solve by graphing: use any method<br><br> x + y = 6<br><br> x - y = 4
jekas [21]
X+y=6
x-y=4
using these equations we solve for either x or y in one and plug it into that variable in the other equation.
x=y+4 so y+4+y=6 so 2y=2 so y=1
now using y=1 put into first equation. x+1=6 so x=5 
so we know our graph goes through the coordinate point (5,1) then just make an x table and use some values to find the corresponding y coordinate and then do that for at least three points or more if needed to find the best fit for graph. Hope this helps walk you through it! Any questions please just ask! Thank you!
