I think it’s b or d i’m sorry if i’m incorrect
Answer:
The correct option is 3) x and y are independent variables, z is a dependent variable.
Step-by-step explanation:
Consider the provided function.
Dependent variables depend on the values of independent variables.
Here z is the function of x and y are the variables.
The value or variable z depends on x and y.
Therefore z is dependent variable.
Also x and y are independent variables,
Hence, the correct option is 3) x and y are independent variables, z is a dependent variable.
Answer:
3. 261 ft³
Step-by-step explanation:
Volume of the figure = ½(volume of cylinder) + volume of triangular prism)
✔️Volume of cylinder = πr²h
r = 3 ft
h = 10 ft
Volume of cylinder = π*3²*10 = 282.74 ft³
✔️Volume of right triangular prism = ½*b*h*l
b = 3*2 = 6 ft
h = 4 ft
l = 10 ft
Volume of triangular prism = ½*6*4*10 = 120 ft³
✔️Plug in the values into the equation:
Volume of the figure = ½(282.74) + 120 = 261.37 ≈ 261 ft³
Answer: $45,83 per moth
Step-by-step explanation:
Considering 12 months and a budget of $ 550, the following account is made: $ 550/12 months = $ 45.83 / month.
In the case of days:
$550/365 days= $ 1,50/day
Question author, it's spelled pi not pie, and we use just use the Greek letter π. Students, demand better from your teachers.
1. Rectangular prism, aka a box. Volume is length times width times height.
V = 5×7×9 = 315 cubic feet
That's cubic feet of course, the product of three lengths. We didn't even need to do the problem, just look for the common answer and pick the one with the right units. I just saw that same pattern in a volume problem yesterday.
Answer: 315 cubic feet, first choice
2. Cylinder, volume is base area times height, πr²h. We have a radius of r=14/2=7 yd and h=8 yd. We're using π=3.14.
V = πr²h = 3.14(7²)(8) = 1230.88 cubic yds
Answer: 1230.9 cubic yards, last choice
