Answer:
The lateral surface is 120 
, which agrees with the third answer option of the list.
Step-by-step explanation:
Notice that the prism has 5 equal lateral faces, which are all rectangles of eight 6". The width of the prisms can be obtained by using the fact that the perimeter of the pentagon is 20", which gives a side length of 20/5 = 4 " which is the same as the with of the lateral rectangles.
Then the lateral area of the prism is:
Lateral area= 5 (6" x 4") = 5 (24) = 120
Answer:
40--C A ---is not[figure it out in your own words,your teacher might suspect something] and B---times 40
Step-by-step explanation:
b--40+40=80 80+40=120 and 120+40=160 A=subtract 40 from all the other answers such as 40-160=120 40-120=80 and 40-80=40
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)
Answer:
531,441 or 1/81
Step-by-step explanation:
You get this answer by multiplying each term by 9. for example: 9x9 is 81 and 81x9 is 729.
Unless this is going backwords and its division. Then the answer will be 1/81.
