Answer:
78 m^2 Unless I got some of the measurements wrong, kinda hard to see them.
Step-by-step explanation:
The surface area will be the sum of the area of each face. so lets see, there is the base (in this orientation) which is a 8x3 rectangle it looks like.
then two trianglular sides with both having a base of 8 and height of 3
then two "roof" pieceswhich are rectangles again, one side of 3 and the other 5.
Now we add each face up.
rectangular base = 3x8 = 24
2 triangular sides = 2(.5*8*3) = 24
2 rectangular roof pieces = 2(5*3) = 30
Now add it all up
24+24+30 = 78
The probability is 50% or 1/2 since the amount of even numbers and odd numbers is equal after 3 is out of the equation.
Answer:-2 3/8
Step-by-step explanation:
(A) 4(x+5). Distribute the 4 (multiply both numbers by 4) and you get
4x+4*5
4x+20
(B) 70 km/h * y hours is 70y km, because you traveled 70 km every hour, so it's 70 times y.
