Answer:
.75
Step-by-step explanation:
8 red marbles, 3 blue marbles, and 1 green marble = 12 marbles
P( not blue) = marbles that are not blue / total
=(8red+1 green) / 12
=9/12
= 3/4
.75
In a quadratic equation, the standard equation is represented as follows:
Ax^2 + Bx + C = 0
where A, B and C are constants and A should not have a zero value.
The values of A, B, and C would be as follows:
A = 1/2
B = -3
C = -2
Hope this answers the question. Have a nice day.
I am not completely sure, but I think it only covers 1 full year plus another semester, again I’m not completely sure.
(x+5)(x+5)
x^2+10x+25(2x-7)
2x^3+20x^2+50x-7x^2-70x-175= 2x^3+13x^2-20x-175
Let x = hours worked as a clerk ($12 per hour).
Let y = hours worked as a cashier ($8.25 per hour).
She worked 55 hours, therefore
x + y = 55 (1)
She earned $585, therefore
12x + 8.25y = 585 (2)
From (1), obtain
y = 55 - x (3)
Substitute (3) into (2).
12x + 8.25(55 - x) = 585
12x + 453.75 - 8.25x = 585
3.75x = 131.25
x = 35
y = 55 - x = 55 - 35 = 20
Answer: a) Office clerk: 35 hours; cashier: 20 hours.
