Answer:

She need to make 98 on the last assignment.

Step-by-step explanation:

Average = 92

x = mark on last assignment

(88 + 97 + 91 + 86 + x) / 5 = 92

To solve for x...multiply 5 on each side

(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5

This would get of / 5 so you don't need to divide by 5

362 + x = 460

Subtract 362 from each side

x = 98

9966 [12]

Answer: (A) and (A)

Step-by-step explanation:

$A=\pi \cdot r^2\\\\\dfrac{A}{\pi}=r^2\\\\\sqrt{\dfrac{A}{\pi}}=r\ \rightarrow \ \bigg(\dfrac{A}{\pi}\bigg)^{\dfrac{1}{2}}\\\\\\\\r=\sqrt{\dfrac{A}{\pi}}\\\\.\ =\sqrt{\dfrac{54\cdot 7}{22}}\\\\.\ =\sqrt{\dfrac{27\cdot 7}{11}}\\\\.\ =\sqrt{\dfrac{189}{11}}\\\\.\ =\sqrt{17.1818}\\\\.\ =4.15$
