SSSSS [86.1K]

Answer:

lets \:  \:  \: find \:  \: the \:  \: radius \\  = 2\pi \: r \\  = 2\pi \: r = 84 \\  =  \frac{2\pi \: r}{2\pi }  =  \frac{84}{2\pi}  \\  = r = 13.37mm

lets \:  \:  \: find \:  \: the \:  \:  \: area \\  = \pi {r}^{2}  \\  = \pi \times  {13.37}^{2}  \\  = 561.55 {mm}^{2}

lets \:  \:  \: find \:  \:  \: the \:  \: diameter \\  = d = 2r \\  = d = 2 \times 13.37 \\  = d = 26.74mm

Answer:

The expressions for the payment made to Mary are,

(Monday) 90 = 15m + b

(Tuesday) 62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

y = 4x + 30

For 20 students,

y = 4(20) + 30 = 110

For Lisa's earnings,

y = 8x + 15

Substituting 20,

y =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

(Btw this is not my work, I got it from someone else on brainly and wanted to help lol)
