An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression 30 divide -6 will be -5.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that we need to divide the integer 30 with a negative integer, therefore, -6. If the given condition is written in the form of an expression then we can write it as,
30 ÷ (-6)
Writing the expression in the form of a fraction,
= 30/(-6)
Break 30 into factors to cancel it out,
= (6 × 5) / (-6)
Cancelling 6 from both the numerator and the denominator
= 5/-1
= -5
Hence, the value of the expression 30 divide -6 will be -5.

Final answer:
The correct option is (B) -5. The expression 30 divide -6 results in -5 after dividing the absolute values and applying the negative sign from the original divisor.
Explanation:
The value of the expression 30 divide -6 is obtained by performing the division of 30 by -6. Division by a negative number yields a negative result. Therefore, the calculation would be:
Take the absolute value of both numbers: 30 (positive) and 6 (positive).
Divide the absolute values: 30 \/ 6 = 5.
Attach the negative sign to the result because the original divisor was negative: -5.
The correct answer is -5, which corresponds to option B.

For a number X, 40% of X is what percentage of 60% of X?
The 40 percent of x is 66.67% of 60 percent of x
Percentage is a way of expressing a fraction or a proportion as a number out of 100. It is often denoted by the symbol "%".
Let x be the number we are considering.
1. 40% of x is equal to 0.40x.
2. 60% of x is equal to 0.60x.
To do that, set up the following expression:
Percentage=0.40x/ 0.60x * 100
Now, cancel out the common factor x:
Percentage = (0.40)/ (0.60) * 100
= (2/3) * 100
= 200 / 3
= 66.67 %
So, 40% of x is 66.67% of 60% of x.

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.
to get an a in a course you must have an average of at least 90 on four tests that are worth 100 points each. Your scores on the first three tests were 87, 92,
and 84 set up and solve an inequality to find the range of the score that you need on the last test to get a course grade of "A"
To get an A in the course, you need to score at least 97 on the last test.
Explanation:To find the range of scores needed on the last test to get an A in the course, we need to set up and solve an inequality. Let's assume that the score on the last test is x. The average of the four tests must be at least 90, so the sum of the scores on the first three tests (263) plus the score on the last test (x) divided by 4 must be greater than or equal to 90.
(87 + 92 + 84 + x)/4 ≥ 90
Combine like terms: (263 + x)/4 ≥ 90
Multiply both sides of the inequality by 4: 263 + x ≥ 360
Subtract 263 from both sides of the inequality: x ≥ 97
Therefore, you need to score at least 97 on the last test to get a course grade of 'A'.

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.

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.
