A symbol that creates a true sentence for x = 6 is '>' i.e.,
12 ÷ x + 2x > 1 2 ÷ (x + 2x)
In this question, we have been given a statement 12 ÷ x + 2x ____ 12 ÷ (x + 2x)
We need to select a correct symbol that would create a true sentence when x = 6.
Consider an expression 12 ÷ x + 2x for x = 6.
= 12 ÷ 6 + 2(6)
= 2 + 12
= 14 ...................(1)
Consider an expression 12 ÷ (x + 2x) for x = 6
= 12 ÷ (6 + 2(6))
= 12 ÷ (6 + 12)
= 12 ÷ 18
= 0.67 ...................(2)
From (1) and (2),
14 > 0.67
Therefore, a symbol that creates a true sentence for x = 6 is '>'
i.e., 12 ÷ x + 2x > 1 2 ÷ (x + 2x)

The values of y varies directly with x. If x=8, when y=16. What is the value of y when x=16???
I need help asap
Answer:
y = 32
Step-by-step explanation:
With this problem, we will use the direct variation form, y = kx.
k = proportionality constant.
Substitute the known inputs of x = 8 and y = 16 into the direct variation form:
y = kx turns into 16 = k(8)
Get k by itself by dividing 8 on both sides:
16/8 = k
2 = k
Now that we know the k value is 2, we input everything we know into the direct variation form if x were equal to 16
k = 2
x = 16
y = kx:
y = 2(16), making y equal to 32

Step-by-step explanation:
An art teacher has a total of \frac{7}{8} pound of clay. The teacher puts \frac{1}{16} pound of clay at each workstation. The teacher sets up an equal number of workstations in each of two classrooms.
How many workstations does the teacher set up in each of the classrooms?
The teacher has set up 7 workstations in each classroom
Total pounds of clay = 7/8 pounds
Pound of clay put at each workstation = 1/16
Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.
Finding the number of workstations:
Number of workstations = Total clay available/Clay set up at each workstation
=(7/8)/(1/16)
=7/8*16/1
= 14 workstations
There are two classes in which these workstations are divided
so, each class will have 7 workstations

A plane flying with a constant speed of 14 km/min passes over a ground radar station at an altitude of 4 km and climbs at an angle of 45 degrees. At what rate is the distance from the plane to the radar station increasing one minutes later?
speed (Δs₁)= change in distance(Δd₁) /(Δt₁)change in time
mathematically,
(Δd₁) /(Δt₁) = Δs₁

Mai wants to make an open-top box by cutting out the corners of a square piece of cardboard and folding up the sides. The cardboard is 10 centimeters by 10 centimeters. The volume () in cubic centimeters of the open-top box is a function of the side length in centimeters of the square cutouts.
Write an expression for ().
What is the volume of the box when =3?
The quantity of space inside a form is measured by its volume.
The volume as a function of side length(x) is: V(x) = 4x³ - 40x² + 100x
What is volume functions?
A three-dimensional space's volume can be calculated. It is frequently quantified numerically by different imperial units or SI-derived units. Volume and length have a mutually reliant relationship.
Given, length of the cardboard = 10 units
Width of the cardboard = 10 units
When side length(x) is removed from the cardboard, the dimension of the box becomes:
Length of the new cardboard = (10 - 2x) units
Width of the new cardboard = (10 - 2x) units
Height of the new cardboard = x units
Therefore, volume of the new cardboard box, V(x)
= Length*Width*Height
= x*(10 - 2x)*(10 - 2x) cubic units
= 100x² - 20x² - 20x² + 4x³
= 4x³ - 40x² + 100x

If the parent function f(x)=|x| is transformed to g(x)=|x|+4 what transformation occurs from f(x) to g(x)
For the transformation of parent function f(x)=|x| to the g(x)=|x|+4, the transformation occurred is 4 units upward.
What is method to obtain a new function from parent function?Assume we have a parent function y=f (x). By simply bringing some constant c, one can generate a new function y=g(x) from parent function. The addition of such a constant alters the parent function's behavior, resulting in shifting, reflecting, extending, or reducing its graph. From that, we can claim that a new function evolves with different properties (such as domain as well as range) than the original function.The function transformation / translation principles are as follows: f (x) + b raises the function b units.
f (x) + b shifts a function b units upward.f (x) − b shifts a function b units downward.f (x + b) shifts a function b units to the left.f (x − b) shifts a function b units to the right.−f (x) reflects a function in x-axis (that is, upside-down).The given parent function is; f(x)=|x|
The transformed function is; g(x)=|x|+4
Thus, from the 1st rule of the transformation we can say that the function has shifted 4 units to upward.

two people start from the same point. one walks east at 4 mi/h and the other walks northeast at 5 mi/h. how fast (in mi/h) is the distance between the people changing after 15 minutes? (round your answer to three decimal places.)
The change in distance between the two after 15 minutes is 3.566 mi/h
Velocity is defined as the rate of change in displacement (distance) with time. It's a vector quantity so it has both magnitude and direction. Velocity is given by the formula:
Velocity = distance / time
If one walks east at 4 mi/h and the other walks northeast at 5 mi/h, then after 15 minutes, their distance are:
distance = velocity * time
distance₁ = 4 mi/h (15 mins)(1 hour/60 mins)
distance₁ = 1 mile east
distance₁ = 5 mi/h (15 mins)(1 hour/60 mins)
distance₁ = 1.25 mile northeast
Using trigonometric function and Pythagorean theorem, we can determine the distance between the two people. (Refer to the attached picture.)
d² = (1.25 sin 45°)² + (1.25 cos 45° - 1)²
d² = 0.795
d = 0.891 mi
After 15 mins, the distance is 0.891 mi and the change in distance in mi/h is
(0.891 mi / 15 mins)(60 mins / hour) = 3.566 mi/h

The most appropriate choice for complementary angle will be given by:
∠A = 27°
What are complementary angles?
Two angles are said to be complementary if the sum of the two angles is 90°
Here,
∠A = (2x + 5)°
∠B = (4x + 19)°
∠A and ∠B are complementary
(2x + 5) + (4x + 19) = 90
6x + 24 = 90
6x = 90 - 24
6x = 66
x = [tex]\frac{66}{6}[/tex]
