What is the coefficient of z in the expression 3x + 2y + z?
Answers
the coefficient is 1. 1z = 1*z = z.
It is clear that coefficient of x is 3 and y is 2. But there is nothing written with z.
So what is the coefficient of z?
When there is no number written before a variable, then its coefficient is 1.
Coefficient is always muktiplied with the variable. So z = 1×z = 1z. But we generally do not write 1 before a variable.
So coefficient of z is 1.

Answer:
x = 5.
Step-by-step explanation:
2x + 1 = 11
Subtract 1 from both sides:
2x = 11 - 1 =10
Divide both sides by 2:-
x = 10/2

B) Which container should be used to fit a dozen film containers with the least amount of wasted space? Explain your reasoning.
At work you get a list of package sizes. Your store has four box sizes that look like they might work. The sizes are given in the form l x w x h. They are 3 in. x 2 in. x 5 in., 4 in. x 3in. x 2 in., 5 in. x 6 in. x 5 in., and 3 in. x 2 in. x 3 in.
Answers
Answer:
(a)18.85 Cubic Inches
(b)The box with dimensions of 4 in. x 3in. x 2 in.
Step-by-step explanation:
Part A
Volume of the 12 Containers
Height =2 Inches
Diameter=1 Inch
Radius=Diameter/2=1/2=0.5 Inch
Volume of a cylinder
Volume of the 12 Containers
Part B
To determine the container which should be used, we first determine the volume of the available boxes.
Volume of the boxes
Volume of box with dimension 3 in. x 2 in. x 5 in.=3X2X5=30 Cubic Inches
Volume of box with dimension 4 in. x 3in. x 2 in.=4X3X2=24 Cubic Inches
Volume of box with dimension 5 in. x 6 in. x 5 in.=5X6X5=150 Cubic Inches
Volume of box with dimension 3 in. x 2 in. x 3 in. =3X2X3=18 Cubic Inches
The box that should be used with the least amount of wasted space is he box with volume 24 Cubic inches. i.e. box with dimensions 4 in. x 3in. x 2 in.
This is because the volume of the box(18 cubic inches) with dimension 3 in. x 2 in. x 3 in. is less than what is required.

Answer:
Annual Interest Rate on purchase is 3 %.
Step-by-step explanation:
Principal, P = $ 18000
Simple Interest , SI = $ 3240
Time , T = 6 years
Let R be the interest rate.
Using Simple interest formula we get,
Therefore, Annual Interest Rate on purchase is 3 %.
3240 = 18 000 * R * 6 /100
3240 = 180*R*6
3240 / (180*6) = R Use your calculator
3 = R
The annual interest rate is 3%.
