Let s=number of seeds and t=number of days...
st=120 and (s+10)(t-2)=120
From the first we can say t=120/s, now using this value of t in the second equation gives us:
(s+10)(120/s-2)=120
(s+10)(120-2s)/s=120
(s+10)(120-2s)=120s
120s-2s^2+1200-20s=120s
2s^2+20s-1200=0
s^2+10s-600=0
(s+30)(s-20)=0, since s>0
s=20, and since she planted s+10 seeds per day to finish two days earlier:
20+10=30
She planted 30 seeds per day.
By definition, the area of a circle is given by:

Where,
r: radius of the circle.
Substituting the values in the given expression, we have:

Rounding to the nearest tenth we have:
Answer:
Approximately needed:
Let vons market receive x loaves. Then savemart received x+12 loaves and Ralphs received x + 12 + 6 = x + 18 loaves, Therefore:-
x + x + 12 + x + 18 = 180
3x + 30 = 180
3x = 150
x = 150/3 = 50
So vons received 50, savemart received 62 and ralph's received 68 loves. Answer
Hi there!
Answer:
<u><em>C.-8.4</em></u>
Step-by-step explanation:
divide by the numbers.
10.8-0.6=18.0=18
9.6-18
subtract the numbers.
9.6-18=-8.4
=-8.4
Hope this helps!
