Answer:
A
Step-by-step explanation:
Associative property:
(a+b)+c=a+(b+c)
(a*b)*c=a*(b*c)
Answer:
4) divide, 5) multiply, 5) divide
Step-by-step explanation:
4) you need to divide to determine the length each individual ribbon will be
5) you need to multiply the price of one shirt by three to find the price of three shirts
6) you need to divide the amount of dog food the dog will eat each day by the amount of dog food to see how many days the food will last.
Basically, this problem wants you to solve the area of the trapezoid given those dimensions, then multiply this to the unit cost to determine the total cost. The formula for the area of trapezoid is written below:
A = (a+b)h/2, where a and b are the lengths of the two bases
A = (15+9)(10)/2 = 120 cm²
Total Cost = 120 cm² * $0.80/cm² = <em>$96</em>
