Could somebody please answer these three questions with simple yet explanatory answers?
Answers
Answer 1
Answer:
This is for #11 and #12.
First lets find the lateral area of each triangle. We will use thefollowing formula:-
lateral area = 4 (1/2 * base * slant height)
11. LA = 4 (1/2 * 8cm * 7.5 cm)
= 120 cm^2
12. LA = 4 (1/2 *14 in * 12in ) =
LA = 336 cm^2
Nowlets find the surface area:-
surface area = lateral area + area of the base
11. S.A. = 120 cm^2+ 8 * 8
= 120 cm^2 + 64
= 184 cm^2S.A. = 336 cm^2+ 14 * 14
12. = 336 cm^2 + 196
= 532 cm^2
LateralArea:-
11. 120 cm^2
12. 336 cm^2
SurfaceArea:-
11. 184 cm^2
12. 532 cm^2

I do believe it is the 4th multiple of 1/5 because the unit fraction is 1/5, so if you multiple 1/5 times 4, i believe you get 4/5.
So, the unit fraction would be 1/5. Keep going from there to 2/5, 3/5, 4/5. So 4/5 was the fourth multiple, However, the answer would have to be a unit fraction and a factor of 4/5, so it has to be 1/5. Equation: 1/5 x 4 = 4/5

Well this would be 23.000 because you know that you can move a number up when the number next to it is more than 5 and the number 1 is next to the zero that is in the tenths place so that will become zero because it is less than 5.

26 you round to 30 and 18 you round to 20 so
30×20=600 there's your estimate!!
30×20=600 there's your estimate!!
You could also round 26 to 25 so there wouldn't be suck a big gap between the real number and the estimate. Hope this helps;)
