Answer: it may be 85 but i didnt get anything else
The expression is r = 500 • 2, where “r” represents the rate.
Answer:
your answer would be a whole number, so your answer would be 1,000 i think.
this should be the answer because if you multiply
9*1000 you get 9000
if you multiply
25 * 1000 you get 25000
so on and so on
Step-by-step explanation:
hope this helps :)
Answer:
68cm^2
Step-by-step explanation:
Well there's not much to explain - the problem statement does it for us.
The surface area is equal to the sum of areas of the walls. There's 2 l*w walls, 2 l*h walls and 2 h*w walls.
SA = 2*l*h + 2*l*w + 2*h*w
SA = 2*4cm*6cm + 2*4cm*1cm + 2*6cm*1cm = 48cm^2 + 8cm^2 + 12cm^2 = 68cm^2
(20+40)+4
So basically the easiest way to remember is for example:
Normal: 69+45
Distributive property: (60+40)+9+5
———————————————————
So if you have 24 you need to distribute the numbers to make them into tens. That’s how you get 4.

I didn’t explain it very well but hope it helped a little bit.
