Answer:
a) [tex]2n+14[/tex]
b) [tex]\frac{nx}{2}[/tex]
Answer:
2(a) 2n + 14
2(b) [tex]\frac{nx}{2}[/tex]
Step-by-step explanation:
For (a), all you have to do is interpret the question itself and turn it into a mathematical operation.
Firstly, as the question has given, the number in (a) should be n.
Therefore, twice of n is 2n, and the sum of 2n and 14 is 2n + 14.
Same goes for (b). The question says a number multiplied by x, meaning nx, and nx halved, getting [tex]\frac{nx}{2}[/tex].
Hope this helped!

Mason was ordering the following rational numbers in math class: -3.3, -15, -8 8/9.
a. Order the numbers from least to greatest.
b. List the order of their absolute values from least to greatest.
c. Explain why the orderings in parts (a) and (b) are different.
Answer:
a) -15, -8, -3.3, 8/9
Step-by-step explanation:
b) 8/9, -3.3(And I say its -3.3, because you need to write it in its original form.), so far its 8/9, -3.3, -8, -15.
c) Because the absolute value is the positive value of that number. (i.e, -3 is 3 places away from 0, so it's absolute value would be 3.)

. If a landfill has a density of 1,200 pounds per cubic yard, what would be the volume required for 15- years worth of MSW to the nearest cubic yard
Here is the full data for the question.
Each person in the state of Texas generate roughly 7.5 pounds of municipal solid waste each day. Of this amount, roughly 35 percent of the waste is currently recycle in Texas. Studies have shown that the maximum amount of waste that could be realistically recycled or otherwise diverted from the landfill is 50 percent.
(NOTE: for tons, use I ton -2,000 pounds unless otherwise specified)
11. For a community/service area of 200,000 people, calculate the amount:
Total MSW each year, in pounds? ? Tons?
II. Total MSW currently recycled each year, in pounds? Tons?
III Amount of the MSW that could realistically be diverted from the landfill if recycling was maximized to the nearest pound.
12. Using the current recycling rate, calculate the amount of MSW sent to a landfill over 15 years period to the nearest pound.
13. If a landfill has a density of 1,200 pounds per cubic yard, what would be the volume required for 15- years worth of MSW to the nearest cubic yard?
Answer:
Step-by-step explanation:
11)
I) The amount of total MSW generated per day in pounds is = 1,500,000 Pounds
The total MSW generated per day in tons is = 750 Tons
The amount of the total MSW generated per year in pounds will be:
= 1,500,000 × 365
= 547,500,000 Pounds
The amount of the total MSW generated per year in tons is
= 750 × 365
= 273,750 Tons
II)
The amount of the total MSW currently recycled per day is pounds
= 1,500,000 × (35/100)
= 525,000 Pounds
Total MSW currently recycled per day in tons is
= 750 × 35/100
= 262.5 Tons
The amount of the total MSW currently recycled per year in pounds is
= 525,000 × 365
= 191,625,000 Pounds
The amount of the total MSW currently recycled each year in tons is
= 262.5 × 365
= 95812.5 Tons
III) The required amount of MSW which could realistically be diverted from the landfill suppose that the recycling was maximized (for each person) is
= 7.5 × (50/100)
= 3.75 Pounds
≅ 4 Pounds
The required amount of MSW which could realistically be diverted from the landfill suppose recycling were maximized (for the total population) is:
= 1,500,000 × (50/100)
= 750,000 Pounds
12)
Applying the current rate of recycling, the amount of MSW sent to landfill over a 15 year period (for each person) is:
= 7.5 × (100-35)/100
= 4.875 Pounds each day
= 4.875 × 365 × 15
= 26690.625 Pounds/ 15 years/person
≅ 26,691 Pounds/ 15 years/person
For 1 year period:
By applying the current rate of recycling, the required amount of MSW sent to landfill over (for total population) is:
= 547,500,000 × (100-35)/100)
= 355,875,000 Pounds
For 15 years period:
By applying the current rate of recycling, the amount of MSW sent to landfill (for total population) is:
= 355875000 × 15
= 5,338,125,000 Pounds
13)
The volume required for the landfill for 15 years worth of MSW is:
= 5,338,125,000/1,200
= 4,448,437.5 Cubic yard
≅ 4,448,438 Cubic yard

To rent a booth at the county fair-grounds costs $42(per day plus a
one-time equipment fee of $85. Write and solve and equation to find the
number of days Ms. Williams rented a booth if she paid a total of $337
Answer:
85 + 42x = 337
x = 6
Step-by-step explanation:
For the equation:
We know there is a one-time fee plus 42 times the number of days you rent the booth for and that the total of the equation should be 337 as that is the total she paid for. We start with the one-time fee (85) and add the county fair-grounds cost (42) multiplied by the number of days you rent the booth for. Since we don't know how many days that is, we will make that our variable which we will call x.
So far we have: 85 + 42x
Now we should set the equation equal to the total amount of money Ms. Williams paid.
This will give us: 85 + 42x = 337
To solve the equation:
Our goal is to find x since that is the number of days Ms. Williams rented the booth for.
First, we subtract 85 from both sides of the equation.
42x = 252
Then, we divide both sides by 42 to isolate our variable, x.
x = 6
X is the number of days Ms. Williams rented the booth for. Therefore, Ms. Williams rented a booth at the county fair for 6 days.

What is the value of cos theta given that (- 5, - 4) is a point on the terminal side of theta ?
Answer:I believe it's -5√41/41
Step-by-step explanation:
The value of [tex]cos\theta[/tex] will be [tex]-0.7813[/tex].
If the point [tex](-5.-4)[/tex] were rotated around the origin, it would form a circle of radius [tex]r[/tex]. Also, if the point were projected to the x-axis, a right-angled triangle would be formed. Then, the value of [tex]cos\theta[/tex], could be obtained by the formula
[tex]cos\theta=\dfrac{x}{r}[/tex]
where
[tex]x=\text{the side of the triangle opposite the reference angle of }\theta\\r=\text{the radius of the circle}[/tex]
From the point on the terminal side
[tex](x,y)=(-5,-4)[/tex]
we can directly get the value of [tex]x[/tex]. But we need to calculate the value of [tex]r[/tex].
To calculate the value of [tex]r[/tex], make use of Pythagoras theorem
[tex]r=\sqrt{x^2+y^2}\\=\sqrt{(-5)^2+(-4)^2}\\=\sqrt{25+16}\\\approx6.4[/tex]
We can now proceed to find the value of [tex]cos\theta[/tex], since we have the values of [tex]x[/tex], and [tex]r[/tex]. Therefore,
[tex]cos\theta=\dfrac{x}{r}\\\\=\dfrac{-5}{6.4}\approx-0.7813[/tex]

Calculate the acceleration of a moving object, given that the object is 500 g and has a a force of 6.5 n
Hello!
[tex]\large\boxed{a = 13m/s^{2}}[/tex]
Use the equation F = m · a to solve where:
F = total force (N)
m = mass (kg)
a = acceleration (m/s²)
We are given the force and mass, so we can plug these values into the equation to solve.
However, mass is used in kilograms, so we must convert from grams to kilograms:
1 kg = 1000 grams
Convert using dimensional analysis or proportions:
[tex]500 g* \frac{1 kg}{1000g} = 0.5kg[/tex]
Plug in the force and mass to solve:
6.5 = 0.5(a)
Divide both sides by 0.5 (Multiply by 2)
a = 13 m/s²

a. yes; measure or interior angle = 120
b. no; measure of interior angle = 120
c. yes; measure of interior angle = 60
d. no; measure of interior angle = 60
Answer:
A: yes, measure of interior angle = 120
Step-by-step explanation:
120 can be divided with 360 without any remainders
if the total degrees can be divided by the interior angle degrees without any remainders, then it tessellates the plane.
Yes, The regular polygon tessellates the plane because the measure or interior angle = 120. hence, the option A is correct.
Regular polygon:We know that 120 could be divided by 360 without having any kind of remainders.
So, in the case when the total degrees could be divided by the interior angle degrees so it should tessellates the plane

If you rotate point (4, 2) 90° and 180° about the origin, how do the x- and
y-coordinates change?
Answer:
(4, 2) to (-2, 4) to (-4, -2).
Step-by-step explanation:
This 90 degree rotation depends on the direction of the rotation. I'm assuming clockwise here.
So (4, 2) rotated 90 degrees puts the point at (-2, 4).
Another 90 degrees (therefore total 180 degrees), and we get to (-4, -2).
