What is the answer I really need help

katrin2010 [14]

Answer:

44.6

Step-by-step explanation:

Since the sides with the two tick marks are equal to 7.4, and there are three of these sides, they are equal to 7.4 times 3, which is 22.2. The remaining sides have 1 tick, meaning they are 11.2, meaning this is 11.2 * 2, which is 22.4. The combined perimeter is 44.6 cm.

Answer:

B. 7.3 %

Step-by-step explanation:

Given:

Initial average grade = 82

Final average grade = 88

Duration for the increase = 3 weeks

Therefore, increase in average grade = Final - Initial = 88 - 82 = 6

Now, percent increase in average grade is given as:

$\% \textrm{increase}=\frac{\textrm{Increase}}{\textrm{Initial grade}}\times 100\\\% \textrm{increase}=\frac{6}{82}\times 100\\\% \textrm{increase}=\frac{600}{82}=7.3\%$

Therefore, the percent increase in her average grade over the 3-week period is 7.3 %.
