Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of bushels of peanuts = 800
Price of each bushels of peanuts = $5.85
And there is mark up rate = 33%
So, Total price would be

If there is spoilage rate = 21%
So, the remaining rate would be 1-0.21=0.79
so, Number of remaining bushels of peanuts would be

So, Selling price per bushel would be

Hence, Option 'c' is correct.
Answer: x<=-5
STEPS:
-4x+10>=5x+55
Subtract the ten from the right and and subtract it from the 55
-4x>=5x+45
Subtract the 5x from the left and subtract it from the -4x
-9x>=45
Divide both sides by -9
x>=-5
Flip sign since u divide by a negative number
x<=-5
Answer:
(1,2021)
Step-by-step explanation:
P and q can vary subject to their sum being 2020.
Consider one parabola with p1 and q1 and another with p2 and q2.
y1=(x1)^2+(p1)(x1)+(q1)
y1=(x2)^2+(p2)(x2)+(q2)
At their intersection, the x and y coordinates are the same.
y1=y2=y
x1=x2=x
x^2+(p1)x+(q1)=x^2+(p2)x+(q2)
Solve for x
x(p1-p2)=q2-q1
x=(q2-q1)/(p1-p2)
Use the constraint that p+q=2020 to eliminate p1 and p2.
p1=2020-q1
p2=2020-q2
x=(q2-q1)/(2020-q1-2020+q2)
x=(q2-q1)/(q2-q1)
x=1
Substitute in the equation for y.
y=1^2+p(1)+q
y=2021
Altogether they swam n + (n - 12) laps
Hope this helps :)
