Answer: 3060 ft^2
Step-by-step explanation:
We will calculate the surface area of the rectangular prism and the triangular prism separately and then subtract off the face that isn't on the surface.
For the rectangular prism:
SA= Ph + 2B
P = 36+36+10+10
P = 92
B = 36*10 = 360
SA = 92*20+2*360
SA = 1840+720
SA = 2560
We subtract off the face on the right of the rectangular prism because it isn't on the surface so we get 2560-200 = 2360
Now for the triangular prism:
SA= Ph + 2B
P = 15+20+25
P = 60
B = 15*20/2
B = 150
SA = 60*10+2*150
SA = 600+300
SA = 900
Again we subtract off the face on the left bescause it's not on the surface so we get 900-200 = 700
Therefore, the total surface area = 2360+700 = 3060 ft^2
Answer:
8
Step-by-step explanation:
First find all factors of 72 and 64 and put them in their respective circles
The factors of 72: 1,2,3,4,6,8,9,12,18,24,36,72
The factors of 64: 1,2,4,8,16,32,64
Now find the factors that both numbers share.
Common factors: 1,2,4,8
The greatest common factor of 72 and 64 is 8.
Answer
a = √b or -√b
Step by step explanation
The square root property :
If x^2 = c, then x = √c or x = -√c
According to the property, we get
a^2 = b,
a = √b or -√b
Thank you.
Answer:
70*60=4200 in 1 hour.
4200*24=100,800 in 1 day.
Answer:
Given a line segment AB
open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet C and D. Draw the line between C and D.
CD is the perpendicular bisector of the line segment AB. Call the point where CD intersects AB E.
