CORRECT OR FASTEST GET BRAINLIEST!!!!!! A standard showerhead in Marty's house dispenses 7 gallons of water per minute. Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x How much water does Marty save each day with the change in showerheads if he uses the shower for 8 minutes each day? the option choices are
4, 12, 32, 53
Answer: 32 gallons
Step-by-step explanation:
Given: Previous rate of dispensing water= 7 gallons per min
If Marty use 8 min showerhead then
Total amount of water dispensed= [tex]7\times8= 56\ gallons[/tex]
After Marty changed the showerhead to energy saving with equation
y=3x, where y is the amount of water dispensed as a function of the number of x minutes for the new showerhead.
When we put x=8 minutes, we get total amount of water dispensed=[tex]3\times8= 24\ gallons[/tex]
Water saved by Marty = 56-24 = 32 gallons
Hence, Marty save 32 gallons each day.
True or false. A figure that has opposite sides with equal lengths and equal slopes and diagonals with slopes that are negative reciprocals must be a rhombus.
Answer:
The statement is false, it describes all parallelogram.
Step-by-step explanation:
The figure that has opposite sides with equal lengths and equal slopes and diagonals with slopes that are negative reciprocals must be a rhombus. This is a true statement
What is a rhombus?A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.
Given:
A figure that has opposite sides with equal lengths and equal slopes and diagonals with slopes that are negative reciprocals must be a rhombus,
Given that it possesses all the characteristics of a parallelogram, a rhombus is regarded as one of the exceptional parallelograms. The two lines of symmetry for a rhombus are its two diagonals. A line that splits an object into two equally sized halves is referred to as the axis of symmetry.
Thus, it is a Rhombus, As the opposite sides are parallel and equal and the diagonal of the rhombus is perpendicular.

Write the equation y=-3/5x+3 in standard form using integer coefficients
Final answer:
To convert the equation y = -3/5x + 3 into standard form with integer coefficients, multiply both sides by 5 to get rid of the fraction, resulting in 5y = -3x + 15. Then, rearrange the terms to obtain the standard form, which is 3x + 5y = 15.
Explanation:
The equation y = -3/5x + 3 is given in slope-intercept form. To convert it into standard form using integer coefficients, we need to rearrange the terms so that all variables and constants are on one side of the equation and the constant is on the other side. The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.
First, multiply both sides of the equation by 5 to clear the fraction:
5y = -3x + 15
Next, move the x-term to the left side of the equation:
3x + 5y = 15
Now, the equation is in standard form with integer coefficients.

Fifty students in the fourth grade class listed their hair and eye colors in the table below: Brown hair Blonde hair Total Green eyes 16 12 28 Brown eyes 14 8 22 30 20 50 Are the events "green eyes" and "brown hair" independent?
The events "green eyes" and "brown hair" are not independent because the probability of a student having both green eyes and brown hair is not equal to the product of their individual probabilities.
Explanation:To determine whether the events "green eyes" and "brown hair" are independent, we need to look at the probabilities of each event occurring separately and together.
The probability of having green eyes (P(Green Eyes)) is the total number of students with green eyes divided by the total number of students, which is 28/50.
The probability of having brown hair (P(Brown Hair)) is the total number of students with brown hair divided by the total number of students, which is 30/50.
The probability of having both green eyes and brown hair (P(Green Eyes AND Brown Hair)) is the number of students with both green eyes and brown hair divided by the total number of students, which is 16/50.
Events A and B are independent if P(A and B) = P(A) * P(B). Using this formula, we can determine if the events are independent:
P(Green Eyes AND Brown Hair) = P(Green Eyes) * P(Brown Hair)
16/50 ≠ (28/50) * (30/50)
Since the probability of having both green eyes and brown hair does not equal the product of the probabilities of having green eyes and having brown hair, these events are not independent.

A line has a slope of -3/4 and passes through the point (–5, 4). Which is the equation of the line?
a)y=-3/4x+1/4
b)y=-3/4x+4
c)y=-3/4x-2
d)y=-3/4x-1/4
Final answer:
The correct equation of a line with a slope of -3/4 that passes through the point (-5, 4) is y = (-3/4)x + 31/4. However, none of the answer choices provided match this equation.
Explanation:
To find the equation of a line with a slope of -3/4 that passes through the point (–5, 4), you can use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point the line passes through.
Plugging in our values we get:
y - 4 = (-3/4)(x - (-5))
This simplifies to:
y - 4 = (-3/4)x - (-3/4)*(-5)
Which further simplifies to:
y - 4 = (-3/4)x + 15/4
To find the y-intercept, we put the equation in slope-intercept form, y = mx + b, by adding 4 to both sides:
y = (-3/4)x + 15/4 + 4
y = (-3/4)x + 15/4 + 16/4
So the final equation is: y = (-3/4)x + 31/4
Looking at the answer choices, there is a mistake in the options provided because none of the options match y = (-3/4)x + 31/4. It's important to convey this discrepancy to the student.

For February, sales revenue is $900,000; sales commissions are 5% of sales; the sales manager's salary is $96,000; advertising expenses are $80,000; shipping expenses total 2% of sales; and miscellaneous selling expenses are $2,100 plus 1/2 of 1% of sales. Total selling expenses for the month of February are:
Final answer:
The total selling expenses for February amount to $245,600, calculated by adding the sales commissions, sales manager's salary, advertising expenses, shipping expenses, and miscellaneous selling expenses together.
Explanation:
To calculate the total selling expenses for the month of February, each component of the selling expenses will be computed based on the provided sales revenue, and then all these components will be summed up.
Sales commissions: 5% of $900,000 = $45,000
Sales manager's salary: $96,000 (fixed cost)
Advertising expenses: $80,000 (fixed cost)
Shipping expenses: 2% of $900,000 = $18,000
Miscellaneous selling expenses: $2,100 + 0.5% of $900,000 = $2,100 + $4,500 = $6,600
Adding all these expenses together:
$45,000 + $96,000 + $80,000 + $18,000 + $6,600 = $245,600
Therefore, the total selling expenses for the month of February are $245,600.

The tongue of a chameleon is one and a half times it's body length. Write this as a decimal
The tongue of a chameleon is 1.5 times its body length when expressed as a decimal.
If the tongue of a chameleon is one and a half times its body length, we express this as a decimal by multiplying the body length by 1.5. For example, if the body length is represented by 1 unit, then the tongue length would be 1 imes 1.5, which equals 1.5. Therefore, the length of the tongue as a decimal is 1.5 times the body length.

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = -16t^2 + 48t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?
The axis of symmetry of a quadratic function indicates the time at which the soccer ball reaches its maximum height in this case.
The axis of symmetry of a quadratic function represented by [tex]h(t) = -16t^2 + 48t,[/tex] where t is time in seconds, is given by the formula t = -b / 2a. In this case, a = -16 and b = 48, so the axis of symmetry is
t = -48 / (2*(-16))
= 1.5 seconds.
The axis of symmetry represents the time at which the soccer ball reaches its maximum height. For this parabolic motion, the ball will rise until it reaches this time, at which point it will start to fall back down.
At t = 1.5 seconds, the ball is at the peak of its trajectory.
The axis of symmetry is useful because it gives us the time at which the event (in this case, reaching the maximum height) happens, and it is a line that divides the parabola into two symmetrical halves.
