Answer:
[tex]\boxed {\boxed {\sf v= 2463.0 \ yd^3}}[/tex]
Step-by-step explanation:
The volume of a cylinder is found using the following formula:
[tex]v= \pi r^2h[/tex]
The height of the cylinder is 16 yards and the radius is 7 yards. Let's use the pi button on a calculator for pi. Substitute these values into the formula.
[tex]v= \pi* (7 \ yd)^2 * 16 \ yd[/tex]
Solve the exponent.
(7 yd)²= 7 yd* 7 yd= 49 yd²[tex]v= \pi * 49 \ yd^2 *16 \ yd[/tex]
Multiply the three numbers together.
[tex]v= \pi *784 \ yd^3\\v=2463.00864041 \ yd ^3[/tex]
Round to the nearest tenth.
[tex]2463.0\underline0864041[/tex]The 0 in the hundredth place tells us to leave the 0 in the tenth place.
[tex]v= 2463.0 \ yd^3[/tex]
The volume of the cylinder is 2463.0 cubic yards.

A number decreased by 9 is 12. Which equation represents this situation?
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.
a class sold tickets to their school play. each of the 23 students in the class sold 4 tickets. the cost of each ticket was 7$
Answer:
would it be $644
Step-by-step explanation:
because if you multiply 24 x 3 that gives you 99 and then multiply 99 by $7 that gives you 644. i could be wrong but i dont know :3
Answer:
$644
Step-by-step explanation:
Step 1)
First we do 23 x 4 to find the total tickets sold and we get 92 tickets sold altogether
Step 2)
Then we do 92 x $7

Jeremy had $32.50 in his savings account. He withdrew $4.50 each week for 3 weeks. How much money did he have left in the account after the 3 withdrawals?
Answer:
Jeremy have 19 dollars left.
Step-by-step explanation:
He withdrew $4.50 3 times, so he withdrew $4.50x3 = $13.50 in total
$32.50 — $13.50 = $19
Jeremy had 19 dollars left on his account.
If θ is an angle in standard position and its terminal side passes through the point (21,-20), find the exact value of \cot\thetacotθ in simplest radical form.
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.

A skateboard ramp at a park has an inclination of 54º and its base is 12 feet long. What is the length of the ramp?
The length of the skateboard ramp at the park is 20.4 feet.
Trigonometric ratioTrigonometric 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
The length of the skateboard ramp at the park is 20.4 feet.

Answer:
[tex]\huge \purple {\boxed { m\angle C = 47\degree}} [/tex]
[tex] \huge \red {\boxed { \widehat{BC}=96\degree}} [/tex]
Step-by-step explanation:
By inscribed angle theorem:
[tex] m\angle C = \frac{1}{2} m(\widehat{AD}) [/tex]
[tex] \therefore m\angle C = \frac{1}{2}\times 94\degree [/tex]
[tex]\huge \purple {\boxed {\therefore m\angle C = 47\degree}} [/tex]
Again by inscribed angle theorem:

[tex] \therefore 48\degree\times 2 = m(\widehat{BC}) [/tex]

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.

Given 300mL of a gas at 17.0 degrees Celsius, what is the volume at 10 degrees Celsius if the pressure remains constant?
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
