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)

What did I do wrong when finding out the sector area? I know the answer I got is wrong so can someone please help me

bonufazy [111]

I believe your mistake is that you are trying to use the sector area formula ti find arc length when there is already a formula for it.
The formula for it is
$2r\pi( \frac{degree}{360} )$
So first substitute the values in and then simplify!
$2(10.5)\pi( \frac{118}{360} )$
Now simplify!
21 × 118 is 2478 so it's
$\frac{2478}{360} \pi$
When divided ou and multiplied, this is 21.62cm!
