Max has a small pickup trunk that carries 3/4 cord of firewood. find the number of trips max would have to make in order to deliver 12 cords of wood?
The number of trips max would have to make in order to deliver 12 cords of wood is 16 trips.
We will use unitary method to solve this problem.
Pick up truck carry ( 3/4 ) cord of firewood in trip = 1
Pick up truck will carry 1 cord of firewood in the trips = ( 1/(3/4) ) trips
= ( 4/3 ) trips
Truck will carry 12 cords of firewood in the trips = 12 × ( 4/3 )
= 16 trips.
Therefore, the number of trips max would have to make in order to deliver 12 cords of wood is 16 trips.

What is circular motion ?
An object moving in a circular motion is defined as rotating while doing so. There are two types of circular motion: uniform and non-uniform. While the angular rate of rotation and speed are constant during uniform circular motion, they are not during non-uniform motion.The problem is asking to find the radius of the orbit of a satellite around a planet, given the orbital speed of the satellite.
For a satellite in orbit around a planet, the gravitational force provides the required centripetal force to keep it in circular motion, therefore we can write:
[tex]\frac{GMm}{r^{2} } = m\frac{v^{2} }{r}[/tex]
where
G is the gravitational constant
M is the mass of the planet
m is the mass of the satellite
r is the radius of the orbit
v is the speed of the satellite
Re-arranging the equation, we find
[tex]\frac{GM}{r} = v^{2}[/tex]
[tex]r = \frac{GM}{v^{2} }[/tex]

What does x equal in this problem ?
Answer:54
Step-by-step explanation:
Triangle ABC lies on the coordinate plane with the vertices A(7,6), B(-3,5) and C(-6,1).
The triangle is transformed using the rule (x, y) --> (x+4, 3y) to create triangle A'B'C'.
What are the coordinates of B'?
The transformation, the coordinates of point B' become (1, 15).
The transformation rule (x, y) → (x + 4, 3y) involves shifting the x-coordinate by 4 units to the right and stretching the y-coordinate by a factor of 3. To find the coordinates of B' after applying this rule, we take the coordinates of point B(-3, 5):
x-coordinate of B' = x-coordinate of B + 4 = -3 + 4 = 1.
y-coordinate of B' = y-coordinate of B * 3 = 5 * 3 = 15.
Therefore, after the transformation, the coordinates of point B' become (1, 15). This means that B' is located 4 units to the right of B along the x-axis and its y-coordinate is three times that of B. The transformation has shifted and stretched the original triangle, resulting in a new position for point B'.

is c=3.75x proportional
Answer:
No
Step-by-step explanation:
If we put x=1 in equation y=x+3.75
y=(1)+3.75
y/x=4.75
If that is proportional then y/x will be the same in each scenario
and if we put x=2 then y=(2)+3.75
y=5.27
y/x=2.875
So, it is not equal, it means that equation is not proportional.
Put the following equation of a line into slope-intercept form, simplifying all fractions.
20x+4y=8
the answer for the given question is slope is -5 and y- intercept is 2.
The slope intercept form of a straight line is one of the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept formula can be used to find the equation of a line (the y-coordinate of the point where the line intersects the y-axis).
The slope-intercept form is y = mx + b , where m is the slope and b is the y-intercept.
y = mx + b
Take 20x off both sides of the equation.
4y = 8 − 20x
Simplify each term by dividing it by 4y = 8 - 20x.
y = 2 − 5x
Reorder 2 and -5x.
y =−5x + 2
Therefore after simplification we get the slope as -5
and the y-intercept as 2

For a college chemistry experiment, students need to prepare a solution containing ethylene glycol. They are each given 20 fluid ounces of a solution containing 2% ethylene glycol, to which they will add another solution that contains 12% ethylene glycol. How much of the 12% solution should they add to obtain a 5% ethylene glycol solution?
Students should add 8.6 fluid ounces of 12% ethylene glycol.
Using the relation between concentration and volume of solution to find the required amount of 12% ethylene glycol to be used. Let the required amount of 12% ethylene glycol be x fluid ounces. Forming the relation as follows -
C₁ × V₁ + C₂ × V₂ = C₃ × V₃
C₁ and V₁ represents 2% ethylene glycol, C₂ and V₂ represents 12% ethylene glycol and C₃ and V₃ represents 5% ethylene glycol solution. As V₂ is x, so, V₃ will be (20 + x).
Keep the values in formula to find the value of x
2%×20 + 12%×x = 5%×(20 + x)
Solving the equation for the value of x
2/100×20 + 12/100×x = 5/100×20 + 5/100×x
0.4 + 0.12x = 1 + 0.05x
Rearrange the equation -
0.12x - 0.05x = 1 - 0.4
Performing subtraction on both sides -
0.07x = 0.6
Shifting 0.07 to Right Hand Side and performing division
x = 0.6 ÷ 0.07
x = 8.6 fluid ounces
Hence, 8.6 fluid ounces of the 12% ethylene glycol should be added.

reflect over x axis transformation represents this rule (x, y) → (–x, y).
How to find the type of transformation?Make a coordinate plot using squared paper.
An illustration.
take the coordinate points (2,3) and (-3,-2)
They are reflected in the x-axis.
The results that you should get are as follows.
(2,-3) and (-3,2)
The y-coordinate is the opposite of the original position, while the x-coordinate is unchanged.
This can be described generally as (x, y) → (–x, y).
When a point is reflected across the X-axis, its X-coordinate stays constant. On the other hand, the Y-coordinate is altered to the opposite sign.
The point (x,y) is therefore reflected across the X-axis as (x,-y).It is known as a reflect over x axis transformation.

Because the variable has an even power, we will see that:
As x approaches -∞, h(x) approaches -∞
As x approaches ∞, h(x) approaches -∞.
Here we have h(x) = -4x^2 + 11
Notice that the variable is squared, this means that the sign does not matter, the outcome of:
-4x^2 will always be negative. So in both ends (when x tends to infinity and negative infinity), we will have the same end behavior.
When we take that limit, -4x^2 will just tend to negative infinity, then in both cases, the function tends to negative infinity.
So we have:
As x approaches negative infinity, h(x) approaches negative infinity.
As x approaches positive infinity, h(x) approaches negative infinity.

Reflection across y = x
When we reflect a point across the line y = x, the x- and y-coordinates swap positions.
What do we mean by Reflection across y = x?When we reflect a point across the line y = x, the x- and y-coordinates swap places. When we reflect over the line y = -x, the x- and y-coordinates swap places and become negated (the signs are changed). The line y = x defines the point (y, x).The line y = -x is the point (-y, -x).Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure. The line of reflection will be directly in the middle of the original figure and its image.Therefore, when we reflect a point across the line y = x, the x- and y-coordinates swap positions.
