Answer:
169 : 289
Step-by-step explanation:
Since the figures are similar then
linear ratio of sides = a : b, then
ratio of areas = a² : b²
ratio of sides = 52 : 68 = 13 : 17
ratio of areas = 13² : 17² = 169 : 289
Answer:
Janice converted a mixed number to the wrong improper fraction.
Step-by-step explanation:
1 batch of stew uses 1 and 2/3 lb meat
Total amount of meat used - 10 and 5/6 lb
x = number of stew batches made
To get number of batches made, divide total meat used by the amount of meat each batch requires:
x = 10 5/6 ÷ 1 2/3
convert mixed fractions to improper fractions:
x = (10x6+5)/6 ÷ (1x3+2)/3
x = 65/6 ÷ 5/3
The fraction in bold numbers is where Janice got it wrong. She changed 1 2/3 to 5/2. (From the question: 10 and StartFraction 5 over 6 EndFraction divided by 1 and two-thirds = StartFraction 65 over 6 EndFraction divided by five halves). 1 2/3 converted to an improper fraction is 5/3. From this point going forward, the calculations are wrong.
It would be 3/14. hope it helps
Answer:
51
Step-by-step explanation:
multiply 5 and 6, then multiply 9 and 9 and then subtract your to answers to get your final answer
The answer to number 1. is 7a+1 if your adding or simplifying.
And number 2 would be 9p^3 - 27p^2 + 48p
