Answer:

292.75mL

Step-by-step explanation:

From the ideal gas equation

PV= nRT

With each symbols having standard meaning

For pressure remaining constant the equation for two states can be written as

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K

Now plugging values in above equation to find V_2

[tex]\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL[/tex]

Therefore, the volume at 10 degrees Celsius = 292.75mL

Answer:

36 sq inches

Step-by-step explanation:

bases are the two parallel sides -- 8" and 4"

height is perpendicular to the base -- 6"

formula for area of a trapezoid:  A = 1/2h·(sum of bases)

A = 1/2(6)(8 + 4)

A = 3(12)

A = 36 sq inches

Answer:

the correct answer is D (what a drag)

Answer:

x - 9 = 12

Step-by-step explanation:

We can use x as "a number"

So the equation so far is just "a number", or x.

Decreased by 9 can also be said as subtracted by 9, so that makes the equation x - 9.

"is 12" can also be said as equals 12, which makes the equation x - 9 = 12

Answer:

_ - 9 = 12

Step-by-step explanation:

You can identify the starting number by adding 9 and 12 together to get 21. The completed equation would be 21 - 9 = 12.

Answer:

[tex]A=339.42\ cm^2[/tex]

Step-by-step explanation:

The diameter of the roll of paper, d = 4.5 cm

Radius, r = 2.25 cm

Height of the roll of papaer, h = 24 cm

We need to find how much is needed to make the inner tube for a roll of paper. The surface area of a cylinder for inner tube is given by :

[tex]A=2\pi r h\\\\=2\times \dfrac{22}{7}\times 2.25\times 24\\\\=339.42\ cm^2[/tex]

So, the required area is [tex]339.42\ cm^2[/tex].

Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? The required sample size is . (Round up to the nearest whole number as needed.) Does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population? A. Yes, because statistics students are typically younger than people in the general population. O B. No, because there is no age difference between the population of statistics students and the general population. O C. No, because statistics students are typically older than people in the general population.

tax

= tax percentage×amount

= 0.04×50

= 2

The tax was $2.

tip

= tip percentage×amount

= 0.10×50

= 5

Based on the information given the total cost is $57.

Using this formula

Total cost=Takeout cost+ Sales tax +Tip

Where:

Takeout cost=$50

Sales tax=(4%×$50)=$2

Tip=(10%×$50)=$5

Let plug formula

Total cost=$50+$2+$5

Total cost=$57

Inconclusion the total cost is $57.

The exact value of the cotangent of theta in simplest radical form is -21/20.

What is the simplest radical form?

The simplest radical form is the expression of a radical without any factors inside the radical that can be further simplified.

To find the exact value of cotangent of theta, we need to find the values of cosine and sine of theta first.

Given that the terminal side of the angle passes through the point (21,-20), we can use the Pythagorean theorem to find the hypotenuse of the right triangle formed by the angle and the x and y-axes:

[tex]h = \sqrt{(21^2 + (-20)^2)} = \sqrt{(841 + 400)} = \sqrt{(1241)}[/tex]

Then, we can find the values of cosine and sine of theta using the x and y-coordinates of the point:

cos(theta) = adjacent/hypotenuse = 21/sqrt(1241)

sin(theta) = opposite/hypotenuse = -20/sqrt(1241)

Now we can find the value of cotangent of theta:

cot(theta) = cos(theta) / sin(theta) = (21/sqrt(1241)) / (-20/sqrt(1241))

= -21/20

Therefore, the exact value of the cotangent of theta in simplest radical form is -21/20.

Answer and Step-by-step explanation:

Section the figure into two 3D shapes.

We get both figures to be a rectangular prism.

The Volume of a rectangular prism is length times width times height.

V (of top Rectangular Prism) = 2 × 2 × 4 = 16

V (of bottom Rectangular Prism) = 6 × 4 × 2 = 48

Now, we add those two volumes together to get the volume of the irregular figure.

16 + 48 = 64.

The volume of the irregular figure is 64 [tex]cm^3[/tex]

Answer:

A)  m = 1300 - 35(8)

Step-by-step explanation:

If your savings account has $1300 in it, and 35 is being taken away every month for 8 months, then you would multiple the months by the amount of money being taken away then subtract the amount from the total amount of money in her account. There for 'm = 1300 - 35(8)'.

The length of the skateboard ramp at the park is 20.4 feet.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let x represent the length of the ramp, hence using trigonometric ratio:

cos(54) = 12/x

x = 12/cos(54)

x = 20.4 feet
