PLZ HELP
1 answer:
Number of pieces times weight of each piece=weight of bag
25*20=500grams per 1 bag
200kg=200000g
weight of 1 bag times x bags=weight of all
500x=200000
divide both sides by 500
x=400
400 bags per day
2.
factor out 6
(6)(y^2+2y-5)=0
reemmber how if we had xy=0, assume x and/or y has to be 0?
assume that
y^2+2y-5=0
use quadratic formula
for ax^2+bx+c=0
x=
so the sum is
+
=
=
easy peasy now
1y^2+2y-5=0
-b/a
-2/1
-2 is the sum
25*20=500grams per 1 bag
200kg=200000g
weight of 1 bag times x bags=weight of all
500x=200000
divide both sides by 500

Answer:
The practical domain of the function is [30,32].
Step-by-step explanation:
The given function is
where, p(h) represents the Vonda's weekly pay as a function of hours worked.
She pays a one time $250 chair rental fee, and earns $40 per hour that she works.
Domain is the set of all possible inputs.
The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.
It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,
Therefore practical domain of the function is [30,32].
