Boyles law involves the pressure and volume of gas in a container. It can be repersented by the formula p sub 1 v sub 1= p sub 2 v sub 2. When the formula is solved for p sub 2, the results is

Answers

Answer 1

Final answer:

Boyle's Law can be rearranged to solve for p sub 2 (final pressure) using the formula p sub 2 = p sub 1 v sub 1 / v sub 2. This shows the inverse relationship between pressure and volume of gas at a constant temperature.

Explanation:

The question is asking to solve the formula representing Boyle's Law (p sub 1 v sub 1 = p sub 2 v sub 2) for p sub 2. Boyle's Law states that the pressure and volume of a gas have an inverse relationship when temperature is held constant. To solve for p sub 2, you rearrange the formula to be p sub 2 = p sub 1 v sub 1 / v sub 2. This formula means that the final pressure (p sub 2) equals the initial pressure (p sub 1) times the initial volume (v sub 1), all divided by the final volume (v sub 2). Therefore, if the volume increases, the pressure decreases, and if the volume decreases, the pressure increases, keeping the gas's temperature constant.

At 9:00 on Saturday morning, two bicyclists heading in opposite directions pass each other on a bicycle path. The bicyclist heading north is riding 5 km/hour faster than the bicyclist heading south. At 10:45, they are 47.25 km apart. Find the two bicyclists’ rates.

Answers

Remember the distance formula, d = rt. After 1.75 hours, they are 47.25 km apart from each other. Let us use A for the distance that the bicyclist heading north has traveled since they met. The distance that the other bicyclist has traveled will, therefore, be (47.25 - A)

A = r(1.75)
A = 1.75r
(47.25 - A) = (r + 5)(1.75)
47.25 - A = 1.75r + 8.75
47.25 - A - 8.75 = 1.75r
38.5 - A = 1.75r
38.5 - A = A
38.5 = 2A
19.25 = A

So A has traveled 19.25 km in 1.75 hours; this gives him a speed of 11 km/h. Bicyclist B has, therefore, traveled 47.25 km - 19.25 km = 28 km in 1.75 hours, giving him a rate of 16 km/h, which fits the provided information.

Answers

E... (.25 × 150) + 50 = 87.5
(.45 × 150) + 20 = 87.5

Answer:

E.The price for travelling 150 miles is same for both company.

Step-by-step explanation:

We are given that Joseph is going on a trip and he needs to rent a car.

Company A

Charge $0.25 per mile plus $50 rental fee.

Company B charges 40.45 per mile plus $20 rental fee.

A.Total distance=150 miles

Company A

Charges for 150 miles=[tex]150\times 0.25=[/tex]$37.5

Total charges=37.5+50=$87.5

Company B

Charges for 150 miles=[tex]150\times 0.45[/tex]=$67.5

Total charge=20+67.5=$87.5

The price for travelling 150 miles is same for both company.

But if distance greater than 150 miles such 155 miles

Company A

Total charge=[tex]155\times 0.25+50=[/tex]$88.75

Company B

Total charges=[tex]155\times 0.45+20=[/tex]$89.75

Company A is better deal if Joseph more than 150 miles.

If distance 145 miles

Price form company A=[tex]145\times 0.25+50=[/tex]$86.25

Price form company B=[tex]145\times 0.45+20=[/tex]$85.25

Company B is better deal if Joseph travel less than 150 miles.

Explanation:
(2x+3)^2 + 8(2x+3) + 11 = 0
To use the u substitution, we will assume that:
2x + 3 = u

Substitute with this in the given expression, we will get:
u^2 + 8u + 11 = 0

The general form of the second degree equation is:
ax^2 + bx + c = 0

Comparing the expression we reached with the general one, we will find that:
a = 1
b = 8
c = 11

The roots can be found using the rule found in the attached picture.
This means that, for the given expression:
u = -4 ± √5

Now, we have:
u = 2x+3
This means that:
at u = -4 + √5
2x + 3 = -4 + √5
2x = -7 + √5
x = (-7 + √5) / 2

at u = -4 - √5
2x + 3 = -4 - √5
2x = -7 - √5
x = (-7 - √5) / 2

This means that, for the given expression:
x = (-7 ± √5 ) / 2

Hope this helps :)

(2x + 3) ^ 2 + 8 (2x + 3) + 11 = 0
Using substitution we have:
u = 2x + 3
We rewrite:

We use resolvent:
u = (- b +/- root (b ^ 2 - 4ac)) / (2a)
We replace:
u = (- (8) +/- root ((8) ^ 2 - 4 (1) (11))) / (2 (1))
u = (- (8) +/- root (64 - 44)) / (2)
u = (- (8) +/- root (20)) / (2)
u = (- (4) +/- root (5))
We return the change:
u = (- (4) +/- root (5)) = 2x + 3
We clear x:
x = (- (7) +/- root (5)) / 2

RHS : -9

LHS ≠RHS

So (2,-4) is not the solution.

b.(-1,2)

5x+2y=-9

LHS: 5x+2y

Plugging (-1,2) in this,

5(-1) +2(2) = -5+4 =-1

RHS : -9

Find the area of the following circle. (Round answer to the nearest whole number.) Circumference = 280 cm. (Hint: Find r from C = 2πr (round r to tenths); then find area). 1) 89 2)560 3)1,989 4)6,246

Answers

Answer:

4)6,246

Step-by-step explanation:

First we will find the value of r.

The formula for circumference is C = 2πr:

280 = 2(3.14)r

280 = 6.28r

Divide each side by 6.28:

280/6.28 = 6.28r/6.28

44.6 ≈ r

The formula for the area of a circle is

A = πr²

Using our value for r, we have

A = 3.14(44.6)² = 6245.9624 ≈ 6246

Area of circle is,

⇒ 11493.2 cm²

What is mean by Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

Circumference of circle = 280 cm.

Now, We know that;

Circumference = 2πr

Hence, We get;

⇒2πr = 280

⇒ 2 × 3.14 r = 380

⇒ 6.28 r = 380

⇒ r = 380 / 6.28

⇒ r = 60.5

Hence, Area of circle is,

⇒ πr²

⇒ 3.14 × 60.5²

⇒ 11493.2 cm²

For quadratic

the discriminant is
.. d = b^2 -4ac

You have
.. a = 2
.. b = -5
.. c = 7
so the value of the discriminant for your equation is
.. (-5)^2 -4(2)(7)
.. = 25 -56
.. = -31

Because the discriminant is negative, the roots of the quadratic are complex.

Reasoning: this is the usual interpretation of the sign of the discriminant. It derives from the fact that the square root of the discriminant is part of the roots of the quadratic. That part will be imaginary when the discriminant is negative.

the thickness of a deep dish pizza is approximately 2 x 10^-1 feet. the thickness of a thin crust pizza is approximately 5 x 10^-2 feet. how many times smaller is the thickness of a thin crust pizza compared to the thickness of a deep dish pizza?

A. 0.25
B.0.4
C4
D25

Answers

The thickness of the deep dish can be evaluated by converting [tex]10^-^1[/tex] to a decimal. [tex]10^-^1= \frac{1}{10}=0.1[/tex]. We multiply 2(0.1) and get 0.2 feet for the thickness of the deep dish pizza.
The thickness of the thin crust can be evaluated in a similar way. [tex]10^-^2=0.01[/tex]. 5(0.01) = 0.05 ft for the thin crust pizza.
We don't know how many times bigger the deep dish is, so that is our variable. That gives us:
[tex]0.05x=0.2[/tex] (the thickness of the thin crust multiplied by an unknown factor equals the deep dish)
Divide both sides by 0.05:[tex]\frac {0.05x}{0.05}= \frac{0.2}{0.05} \\ x=4[/tex]
The deep dish is 4 times bigger than the thin crust, which means the thin crust is 4 times smaller than the deep dish.

The thickness of a thin crust pizza is 4 times smaller than the thickness of a deep dish pizza.

The question asks us to compare the thickness of a deep dish pizza to that of a thin crust pizza and determine how many times smaller the thin crust is. The deep dish pizza has a thickness of 2 x 10⁻¹ feet and the thin crust pizza has a thickness of 5 x 10⁻² feet. To find how many times smaller the thin crust is, we divide the thickness of the thin crust by the thickness of the deep dish pizza:
(5 x 10⁻² feet) / (2 x 10⁻¹ feet) = 0.25

If 543 planes leave from JFK airport and each plane has 228 passengers, how many people have flown out of JFK? people;

Answers

123,804 people have flown out of JFK airport

123,804 people have flown out of JF-K airport based on the assumption of full plane occupancy. Real-world variations and logistical complexities may impact the actual number.

To find the total number of people who have flown out of JF-K, you can multiply the number of planes by the number of passengers per plane.

543 planes * 228 passengers/plane = 123,804 people

Therefore, 123,804 people have flown out of JF-K airport.

It's important to note that this calculation assumes each plane is fully occupied and that there are no variations in passenger counts.

In reality, the number of passengers on each plane may vary, and factors such as seat availability, ticket sales, and other considerations can affect the actual number of people who have flown out of JF-K.

In graph 2, the dots are scattered and also no association.

What is an association?

An association (relationship) between two numerical variables can be described by its form, direction, strength, and outliers. A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables.

For the given situation,

There are four new consignments of t-shirts.

Each consignment contained t-shirts of five different sizes.

Graph is plotted as shown below between each of the t-shirt sizes and the profit earned on each new size.

If one variable increases as the other variable increases, there is said to be a positive association.

Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.

No association means that there is no line and all the dots are scattered.

From the graph shown, in graph 2 the dots are scattered. Thus no association.

Hence we can conclude that in graph 2, the dots are scattered and also no association.

First we look for the hypotenuse of both triangles.
Left triangle:
Sine (68.1) = (1.75) / (h)
h = (1.75) / Sine (68.1)
h = 1.886108667
h = 1.9m
Right triangle:
Sine (49.4) = (1.75) / (h)
h = (1.75) / Sine (49.4)
h = 2.304841475
h = 2.3m
Finally adding the perimeter:
P = 5 + 1.9 + 2.75 + 2.3
P = 11.95 m
Answer:
she will need to build 11.95 m of fence
