nearest tenth. Use 3.14 for pie
Answer:
V = 251.3
Step-by-step explanation:
Volume of a Cone formula:
V = πr²(h/3)
Given:
r = 4.9
h = 10
Work:
V = πr²(h/3)
V = 3.14(4.9²)(10/3)
V = 3.14(24.01)(10/3)

Answer:
A) By using the Pythagorean Theorem, we will see that [tex]8^2 + 15^2 = 17^2[/tex]. If we simplify it, we will find that the hypotenuse of Δ[tex]ABC = 17[/tex]
B) approximately [tex]18.79[/tex]
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is [tex]leg^2 + leg^2 = hypotenuse^2[/tex]
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, [tex]8^2 + 17^2 = AD[/tex].
[tex]8^2 + 17^2 = 64 +289[/tex][tex]64 + 289 = 385[/tex][tex]\sqrt{385} \\[/tex] ≈ [tex]18.79[/tex]Hope you do well on the rest of your math problems :D

Turn 6/10 into an equivalent fraction with a denominator of 80.
Answer:

Now assume a 95% confidence level. Without performing any calculations, complete the sentence below. The margin of error for a 95% confidence level will be
Answer: greater than 0.3
Step-by-step explanation:
On edge
The margin of error for a 95% confidence level will be greater than 0.3.
What is a confidence interval?A random population parameter is likely to be included in a confidence interval, which is a range of values that is limited by the statistic's mean. The confidence level is the percentage of probability, or certainty, that, after repeated random sample draws, the confidence interval would include the true population parameter.
Given:
A confidence level is 95%.
The formula to calculate the margin of error:
The margin of error = Z x S/√n.
Where S is the standard deviation and n is the sample size.
The corresponding z-score of the confidence level is 95%.
So, the margin of error will be always greater than 0.3.
Therefore, the margin of error will be always greater than 0.3.

The answer for the following question is option A.
If a snowball melts so that its surface area decreases at a rate of 3 cm2/min, find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm. (Round your answer to three decimal places.)
Answer:
The diameter decreases at a rate of 0.053 cm/min.
Step-by-step explanation:
Surface area of an snowball
The surface area of an snowball has the following equation:
[tex]S_{a} = \pi d^2[/tex]
In which d is the diameter.
Implicit differentiation:
To solve this question, we differentiate the equation for the surface area implictly, in function of t. So
[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]
Surface area decreases at a rate of 3 cm2/min
This means that [tex]\frac{dS_{a}}{dt} = -3[/tex]
Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.
This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So
[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]
[tex]-3 = 2*9\pi\frac{dd}{dt}[/tex]
[tex]\frac{dd}{dt} = -\frac{3}{18\pi}[/tex]
[tex]\frac{dd}{dt} = -0.053[/tex]
The diameter decreases at a rate of 0.053 cm/min.
