Answer:
When discounted 10% you will pay 198$.
220-22=198$
We translate the data of Mary as (15,90) and (8, 62). In this case, the slope is (90-62) / (15-8) or equal to 4. The equation is y-y1 = m (x-x1) where m is the slope. Substituting, y - 90 = 4 (x-15) or equal to y = 4x + 30. <span> Lisa receives half the base amount that Mary does, but she is paid twice as much per student so the equation that of Lisa is y = 8x + 15.
when x is 20
</span><span>Mary : y = 4*20 + 30 =110
</span>Lisa : y =<span> 8*20 + 15 = 175.
Hence Lisa earns more.</span>
Answer:
13
Step-by-step explanation:
you needed to do alt of things with your math but yes its 13
Answer:C = 2 π r
r = C / 2 π
r = 907.46 / 2 π
r= 144.42
Since Diameter is double of radius so diameter is 2 x 144.42 = 288.84 units
