The polynomial expression that represents the perimeter is (3x^3 +3x -148)ft and the value is 182ft
what is a polynomial?Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.
Perimeter of the triangle is the sum of the sides of the triangle which is = 2x^2 -120 + x^2 -5x +8x -28
Perimeter = (3x^2 +3x -148)ft
when x = 10
Perimeter = 3(10)^2 +3(10) -148 = 182ft
In conclusion the expression (3x^2 +3x -148)ft is the expression for the perimeter of the triangle and the value is 182ft

If Malik has 4 times as many nickels as quarters and they have a combined value of 315 cents, how many of each coin does he have?
Set up your equation
4q + q = 315 Add (q = amount of quarters)
5q = 315 Divide
q = 63
Therefore he has 63 quarters.
To find the amount of nickels, multiply 4 and 63
4 x 63 = 252
Therefore he has 63 quarters and 252 nickels.

Write an equation in slope-intercept form of the line given:
Answer: y=-x
Step-by-step explanation:
Choose 2 coordinates: (-2,2) and (2,-2)
Let us find the slope m:
[tex]\displaystyle\\m=\frac{y_2-y_1}{x_2-x_1} \\\\x_1=-2\ \ \ \ \ x_2=2\ \ \ \ \ y_1=2\ \ \ \ \ y_2=-2\\\\m=\frac{-2-2}{2-(-2)} \\\\m=\frac{-4}{2+2} \\\\m=\frac{-4}{4} \\\\m=-1\\[/tex]
Hence,
y=-x+b
To find the coefficient b, choose any coordinate belonging to the given line, for example (-2,2):
2=-(-2)+b
2=2+b
0=b
Hence, b=0
Thus, y=-x

Step-by-step explanation:
9/12=0.75
0.75 x 12 = 9
0.75 inches per hour
Answer: 4.5 hours.
Step-by-step explanation:
Use a proportion.
3 3/8 = 3.375
9 inch is to 12 hours as 3.75 inches is to x hours.
9/12 = 3.375/x
3/4 = 3.375/x
3x = 4 * 3.375
x = 4 * 1.125
x = 4.5
Answer: 4.5 hours
Write an equation of the line that passes through the pair of points. (5/12, −1), (−3/4, 1/6)
The equation of the line can be written as y = -x - (7/12).
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
Given that the line passes through (5/12, −1) and (−3/4, 1/6). Therefore, the slope of the line can be written as,
Slope of the line = [(1/6) - (-1)] / [(-3/4) - (5/12)]
= [(1/6) + 1] / [(-3/4) - (5/12)]
= (7/6) / [(-9-5)/12]
= (7/6) / (-14/12)
= -1
Now, the equation can be rewritten with slope and a point as,
y = mx + c
(1/6) = -1(-3/4) + C
(1/6) = (3/4) + C
C = (1/6) - (3/4)
C = (2/12) - (9/12)
C = (-7/12)
Therefore, the equation of the line can be written as,
y = mx + c
y = (-1)x + (-7/12)
y = -x - (7/12)
Hence, the equation of the line can be written as y = -x - (7/12).

Explanation:
A conditional statement is of the form "if..., then..."
For example, "If it rains, then the grass gets wet" is a conditional statement.
We can have a basic template of "If P, then Q" to represent any conditional. The P and Q are placeholders for logical statements.
The converse of that conditional is "If Q, then P". We swap P and Q.
------------
So let's say we had this original conditional:
"If the lines are parallel, then alternate interior angles are congruent"The converse would be:
"If the alternate interior angles are congruent, then the lines are parallel"Similar ideas apply for the other converses as well.
Answer:
If alternate interior angles are congruent, then lines are parallel.
If alternate exterior angles are congruent, then lines are parallel.

The converse, inverse, contrapositive and biconditional for the given sentences has been written down for a better understanding.
What are inverse statements?Two assertions that are logically opposed to one another are referred to be inverse statements. An inverted statement would be "It is raining" and "It is not raining."Biconditional statements can be both true and untrue depending on the veracity or falsity of each of its component elements. For instance, "If it is raining, then the ground is wet" is a biconditional statement because if it is raining, the ground will be wet, and if it is not raining, the ground won't be wet. In other words, the truth or falsehood of the first part (it is raining) determines the truth or falsehood of the second part.

slide and its ladder form a right triangle with the ground, with the
slide representing the hypotenuse. The top of the ladder is 10 feet above
the ground, and the bottom of the ladder is 12 feet from the bottom of
the slide. What is the length of the slide to the nearest tenth of a foot?
1. Use the information in the problem to label the diagram.
Answer:
1. The problem involves finding the length of a slide about a ladder. The slide and the ladder form a right triangle, with the ground and the slide as the hypotenuse.
2. The top of the ladder is 10 feet above the ground, and the bottom of the ladder is 12 feet from the bottom of the slide.
3. In order to solve this problem, a diagram can be used to represent the scenario.
4. Label the bottom of the slide as point A, the bottom of the ladder as point B, and the top of the ladder as point C.
5. Draw a straight line from point A to point B and label it 12 feet.
6. Draw a straight line from point B to point C and label it 10 feet.
7. Draw a straight line from point A to point C, which is the hypotenuse of the triangle.
8. Use the Pythagorean Theorem to find the length of the hypotenuse.
9. The Pythagorean Theorem states that a2 + b2 = c2, where a and b are the sides of the triangle and c is the hypotenuse.
10. In this problem, a is 12 feet, and b is 10 feet. Plugging these values into the equation, we get 122 + 102 = c2. Solving for c, we get that the length of the slide is 14.04 feet to the nearest tenth of a foot.

From the question, we have the following parameters that can be used in our computation:
Number of days to ripe = 80 days
Date the tomato seed is eaten = July 29
The above parameters can be represented using the following subtraction equation:
The date you planted the seeds = Date the tomato seed is eaten - Number of days to ripe
Substitute the known values in the above equation, so, we have the following representation
The date you planted the seeds = July 29 - 80 days

Probability of landing on red 0.9%, when Yolanda spun the dial 1000 times.
What is probability?
The probability of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anywhere between 0 and 1, as the favorable number of outcomes can never exceed the total number of outcomes.
A spinner with 10 equally sized slices has 4 yellow slices, 4 red slices, and 2 blue slices.
Yolanda spun the dial 1000 times.
P( getting red) = 19/1000
From the chart, there are 19 red out of 1000
Experimental probability of landing on red
= Number of red outcomes / Total number of spins
= 9/1000
Experimental probability of landing on red 0.009.

How are credit card finance charges computed?Credit card attracts finance charges.
The finance charges are the interest for using some credit to finance purchases.
Most finance charges are based on the annual percentage rate (APR), which may also be used to obtain the monthly percentage rate (MPR) by dividing the APR by 12.
The finance charge is applied to the unpaid balance at the end of the period, which may be daily, weekly, or monthly.
Carryover balance = $600
Annual percentage rate (APR) = 18.99%
Monthly percentage rate (MPR) = 1.5825% (18.99% ÷ 12)
Recurring monthly purchase = $70
Monthly payment = 7% of the ending balance
The finance charge for month 1 = $10.60 ($600 + $70 x 1.5825%)
Payment for month 1 = $47.64 ($680.60 x 7%)
Carryover balance for month 1 = $632.96 ($680.60 - $47.64)
The finance charge for month 2 = $11.12 ($632.96 + $70 x 1.5825%)

If the point D (-6, 9) is reflected over the x-axis, the coordinates of D’ would be?
Answer:
D'(-6, -9)
Step-by-step explanation:
When a point is reflected over the x-axis, the x-coordinate remains the same. The reflected point is the same distance from the x-axis as the original point, but it's on the other side of the x-axis, so the y-coordinate changes sign.
In general, point (x, y) reflected over the x-axis becomes point (x, -y).
Here, point D(-6, 9) becomes point D'(-6, -9).
