This formula only applies if the track is circular.  If it is, then we write the equation:

2*r*pi=400

Dividing by 2pi, we see that:

r=200/pi

This is approximately 63.66.

Write the mixed number as a percent <br><br> 2 41/50
ehidna [41]

Answer:

∴ 2 \frac{41}{50}  = 282 %

Step-by-step explanation:

2 \frac{41}{50}

= [( 2 × 50) + 41] ÷ 50

=  ( 100 + 41) ÷ 50

= \frac{141}{50}

=( \frac{141 }{50} ) × \frac{2}{2}

= \frac{282}{100}

= 282 %

∴ 2 \frac{41}{50}  = 282 %

igomit [66]

ANSWER:

a) y = 15x + 75

b) 50 weeks

EXPLANATION:

P A R T   A

2 weeks, 105 dollars --> (2, 105)

5 weeks, 150 dollars --> (5, 150)

<u />

<u>if we use slope intercept form (y=mx+b), we must:</u>

1) find the slope

y2 - y1 -->> 150 - 105 = 45

x2 - x1 -->> 5 - 2 = 3

45/3 = 15

2) find the y intercept

y = 15x + b -->> 150 = 15 (5) + b -->> 150 = 75 + b -->> 75 = b

--------------------------------------------------------------------------------------------

P A R T   B

y = 15x + 75 (substitute the y with 825 because that is the goal)

825 = 15x + 75 (solve normally)

750 = 15x

50 = x
