Answer:
A. 219.80 square centimeters
Step-by-step explanation:
The total surface area is given by ...
A = πr(r+s)
where r is the radius and s is the slant height. Filling in the given numbers, you get ...
A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²
Convert 12 pounds to ounces which is 192 ounces.
Divide the price by the ounces. That would get $0.09765625 rounded to $0.10 per ounce.
Answer:
the first graph
Step-by-step explanation:
Answer: 9 inches
Step-by-step explanation:
To solve this problem, we need to recognize that Harry's age is given as "n". We can use this value and the given information to write expressions representing each person's age.
For Example, Jo is 2 years older than Harry and Harry's age is represented by the variable n. This means that n (Harry's age) plus 2 would equal Jo's age. This can be represented by the expression: n +2.
Next, we know that Kate is twice as old as Jo, and Jo's age is represented by the expression n+2. This means that 2 times Jo's age would be equal to Kate's age, or Kate's age = 2(n+2) or 2n +4.
Therefore, your answer is that Jo's age is n + 2 and Kate's age is 2n + 4.
Hope this helps!
