Answer:
9Kg, 18Kg and 63 Kg
Step-by-step explanation:
Sum the parts of the ratio, 1 + 2 + 7 = 10 parts
Divide the weight of sand by 10 to find the value of one part of the ratio
90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus
2 parts = 2 × 9 Kg = 18 Kg
7 parts = 7 × 9 Kg = 63 Kg
Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg
Answer:
2: The perimeter of the base is 37 units.
Step-by-step explanation:
1. A = LW = 21 * 16 = 336 units^2 True
2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units False
3. H = 21 units True
4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2 True
Final Result :
