Find the height and slant height of the cone. Round your answers to the nearest whole number.
Answer:
Height = 4 cm and slant height = 5 cm
Step-by-step explanation:
Given that,
The surface area of the cone, A = 75.4 cm²
Radius, r = 3 cm
The surface area of the cone is given by the formula as follows :
[tex]A=\pi r^2+\pi rl[/tex]
Put all the values,
[tex]75.4=3.14\times 3^2+3.14\times 3\times l\\\\75.4=28.26+9.42l\\\\75.4-28.26=9.42l\\\\47.14=9.42l\\\\l=\dfrac{47.14}{9.42}\\\\l=5\ cm[/tex]
Also,
[tex]l^2=r^2+h^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{5^2-3^2}\\\\h=4\ cm[/tex]
Hence, the height of the cone is 4 cm and the slant height is 5 cm.

A total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets. How many adult tickets were sold?
The number of adult tickets sold will be 275.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that a total of 494 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer student tickets sold than adult tickets.
Assume that the number of adult tickets sold are [x] and the student tickets sold are [y]. Then -
x + y = 494
y = x - 56
So, we can write the equation as -
x + x - 56 = 494
2x = 550
x = 275
Then, we can find [y] as -
y = 275 - 56 = 219
y = 219
Therefore, the number of adult tickets sold will be 275.

What is the perimeter and area of this????? Please help fast
Hi there!
[tex]\large\boxed{\text{ P = 31ft, A = 35ft}^2}[/tex]
Perimeter: Add up all the side lengths.
14 + 10 + 7 = 31 ft.
Area: Use the following formula:
A = 1/2(bh) where:
b = bass
h = height
Thus:
A = 1/2(10 · 7) = 35 ft²

17. The present age of a father and his son is 50yrs and 20yrs respectively. How many years ago
the product of their ages was 451.
Answer:
9 yrs ago
Step-by-step explanation:
(50-x)(20-x) = 451
x^2-70x + 1000 = 451
x^2-70x + 549 = 0
(x-9)(x-61) = 0
x = 9 (if it was 61 yrs ago, the father and son both wouldnt be a live)

T
175°
H
57°
F
Answer:
m<G = 59°
Step-by-step explanation:
Recall: the angle formed outside a circle when 2 secants intercept is equal to half of the difference of the intercepted arcs
m<G = ½(arc TE - arc HF)
m<G = ½(175 - 57)
m<G = ½(118)
m<G = 59°
A circular path 4 feet wide has an inner diameter of 250 feet. How much farther is it around the outer edge of the path than around the inner edge? Round to nearest hundredth. Use 3.14 for π.
The outer edge of the path is ??? feet farther around than the inner edge.
Answer:
25.13
Step-by-step explanation:
the inner circle is 1570.8 and the outer is 1595.93
Hope this helps! :)
Have a great weekend!! :)
Answer:
50.24 ft
Step-by-step explanation:
diameter = 250 ----- radius = 125 (radius of the smaller circle)
125+4 = 129 ( radius of the bigger circle)
129-125 = 4
4² x pi = 16x 3.14 = 50.24

[tex]\lim_{x \to -3} \sqrt{x^2 - 8}[/tex]
Here we have
[tex]\lim_{x \to -3} f(x)=f(x)[/tex]
Therefore
[tex]\lim_{x \to -3} \sqrt{x^2 - 8} = \lim_{x \to -3} \sqrt{(-3)^2 - 8} = \lim_{x \to -3} \sqrt{9 - 8} = \lim_{x \to -3} \sqrt{1}[/tex]
[tex]\lim_{x \to -3} \sqrt{1}= \lim_{x \to -3} 1 = 1[/tex]
A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a standard deviation of 86 minutes with a mean life of 505 minutes. Of the claim is true, in a sample of 120 batteries, what is the probability that the mean battery life would be greater than 523.8 minutes
Answer:
0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Standard deviation of 86 minutes with a mean life of 505 minutes.
This means that [tex]\sigma = 86, \mu = 505[/tex]
Sample of 120:
This means that [tex]n = 120, s = \frac{86}{\sqrt{120}}[/tex]
What is the probability that the mean battery life would be greater than 523.8 minutes?
This is 1 subtracted by the p-value of Z when X = 523.8. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{523.8 - 505}{\frac{86}{\sqrt{120}}}[/tex]
[tex]Z = 2.39[/tex]
[tex]Z = 2.39[/tex] has a p-value of 0.9918.
1 - 0.9918 = 0.0082
0.0082 = 0.82% probability that the mean battery life would be greater than 523.8 minutes
|x+4|=6 please help but give me an answer other than 2
Answer: -10 (or 2)
Step-by-step explanation: Absolute value gets rid of the negative so you can solve it with a positive or negative number as long as the interger still has the same value. (|-2|=2 and |+2|=2) so |-10+4|=6

Can side lengths 3, 4, and 5 form a right triangle
Answer:
Yes it can! Plz the Brainliest!
Step-by-step explanation:
A right triangle is defined as a triangle with sides in the ratio 3:4:5. Pythagorean Doubles are triangles whose sides have had a ratio of the whole numbers as their sides. Even if the sides are multiplied by any number, the result is still a right triangle with sides in the ratio 3:4:5. For instance, 6, 8, and 10 are all numbers.

Write an inequality for the sentence: The maximum height his 45 feet.
Answer:
h ≤ 45
Step-by-step explanation:
The maximum height is 45 feets
Let the height of the object = h
Hence, the sentence means that the height, h of the object cannot be beyond 45 feets ;
This means the height can be any number of feets less than or equal to 45 feets
Hence, h ≤ 45
