Answer:
S.A = 730mm²
Step-by-step explanation:
Since the solid is made up of two rectangles. Then the surface area (S.A) would be
S.A = area of first rectangle + area of second rectangle
Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is
25mm x 21mm = 525mm²
Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is
41mm x 5mm = 205mm²
Therefore
S.A = 525mm² + 205mm² = 730mm²
We are given that each bag of trail mix consumes 2.3 oz of nuts. To know the amount of bags of trail mixes that can be made using 27.6 oz of nuts, all we have to do is cross multiplication as follows:
2.3 oz of nuts ............> 1 bag of trail mix
27.6 oz of nuts ...........> ?? bag of trail mix
number of bags = (27.6*1) / 2.3 = 12 bags
A) 144/4 = 36 metres per side
b) 18*3 = 54
54+54+18+18= 144 metres
dimensions would be 54 by 18
Answer:
B. 2(n + 24)
Step-by-step explanation
you need to find the sum of n and 24 first so you put it in brackets. To multiply by two just put 2 on the outisde of the brackets.
Hope this helps
