A cone has a height of 5 inches and a radius of 4 inches. What is its volume?
Use a ~ 3.14 and round your answer to the nearest hundredth.
9514 1400 393
Answer:
83.73 in³
Step-by-step explanation:
It is appropriate to use the formula for the volume of a cone:
V = (1/3)πr²h
V = (1/3)(3.14)(4 in)²(5 in) ≈ 83.73 in³
The volume of the cone is about 83.73 in³.
You walk 2/5 miles to a clothing store. Then you walk another 1/2 miles to a music store. How many miles have you walked in all?
Answer:
9/10ths of a mile. Or 0.9 miles.
Step-by-step explanation:
To get the total it's helpful to look at it in decimals:
2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)
1/2 mile = 0.5 miles
Add them together = 0.9 miles.
Which is 9/10ths of a mile.
The total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.
It is given that you walk 2/5 miles to a clothing store and then walk another 1/2 miles to a music store.
We have to find out the total distance in miles that you have walked.
What do you mean by fractions ?
A fraction can be defined as a portion or part of any quantity or it defines a part of a whole.
As per the question ;
You walk 2/5 miles to a clothing store
and
then ; walk another 1/2 miles to a music store.
To find out the total distance walked by you in total , we need to add both the distances given in the question.
i.e.,
Total distance will be ;
= [tex]\frac{2}{5}[/tex] + [tex]\frac{1}{2}[/tex]
= [tex]\frac{4+5}{10}[/tex]
= [tex]\frac{9}{10}[/tex] miles
or
= 0.9 miles
Thus , the total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.

Find the inverse of the function.
Answer:

Step-by-step explanation:
[tex]f(n) = \sqrt[3]{n} -2[/tex]
[tex]y = \sqrt[3]{n} -2[/tex]
[tex]y = n^{1/3}-2[/tex]
[tex]n = y^{1/3} -2[/tex]

[tex]y = (n + 2) ^3[/tex]
[tex]f^{-1}(n) = (n + 2)^3[/tex]
Hope this helps!
Answer:
Option A
Step-by-step explanation:
f(n) =∛n-2
y= ∛n-2
Interchange y and n
n =∛y-2
Subtract -2 on both sides
n+2 = ∛y
both both sides to the 3rd power:
(n+2) to the 3rd power = y
Inverse :
f-1(n) = (n+2) to the 3rd power (option A)

What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
1/ 3 × 2 /5
Now, to multiply we have multiply numerator and denominator.
1/ 3 × 2 /5
=(1 x 2)/ ( 3 x 5)
= 2 /15
Now, 2/ 5 ÷ 3/ 5
We have to divide the fraction.
Fraction does not support division.

An envelope is 48 centimeters wide, and it measures 52 centimeters along the diagonal. How tall is the envelope?
Answer:
20 cm.
Step-by-step explanation:
Pythagorean Theorem a^2 + b^2 = c^2 (c is the hypotenuse).
Plug it in.
48^2 + b^2 = 52^2
2,304 + b^2 = 2,704
Isolate the variable.
b^2 = 400
b = 20

Harry fills up his Jeep with gasoline and notes that the odometer reading is miles. The next time he fills up his Jeep, he pays for gallons of gasoline. He notes his odometer reading is miles. How many miles per gallon did he get?
Complete question :
Harry fills up his Jeep with gasoline and notes that the odometer reading is 23,568.7 miles. The next time he fills up his Jeep, he pays for 12.6 gallons of gasoline. He notes his odometer reading is 23,706.3 miles. How many miles per gallon did he get?
Answer:
10.9 miles per gallon
Step-by-step explanation:
Given that :
Odometer reading when filled up with gasoline = 23,568.7 miles
Odometer reading with 12.6 gallons of gasoline = 23,706.3 miles
Miles per gallon gotten :
(Current Odometer reading - reading when filled up) / gallon of gasoline
(23706.3 - 23568.7) / 12.6
= 10.920634
= 10.9 miles per gallon

A certain model of remote-control Stanley garage door opener has nine binary (off/on) switches. The homeowner can set any code sequence. (a) How many separate codes can be programmed
Answer:
[tex]Codes= 512[/tex]
Step-by-step explanation:
Given
[tex]Switches = 9[/tex]
[tex]Controls = 2[/tex] ------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
Up till the ninth switch
So, we have that:
[tex]Codes= 2 * 2 *2*2*2* 2 *2*2*2[/tex]
[tex]Codes = 2^9[/tex]
[tex]Codes= 512[/tex]
Hence, there are 512 possible codes
Why are arithmetic sequences discrete data?
Answer:
If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
Step-by-step explanation:
Answer:
A sequence is a discrete structure used to represent an ordered list.
Step-by-step explanation:
Discrete values are values between the terms if the sequences are not included in the sequence. If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So in that sense, yes, sequences are discrete. A sequence is a discrete structure used to represent an ordered list. A sequence is a function from a subset of the set of integers (usually either the set {0,1,2,. . .} or {1,2, 3,. . .}to a set S. We use the notation an to denote the image of the integer n. We call an a term of the sequence.
Some parts of California are particularl earthquake prone. Suppose in one metropolitan area, 40% of all homeowners are insured against earthquake damage. Four homeowners are selected at random. Let X denote the number among the four who have earthquake insurance. Assume that the event of each homeowner having or not having insurance is independent.
Required:
a. Find the probability mass function of X?
b. What is the most likely value for X?
c. What is the probability that at least two of the four selected have earthquake insurance?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Percentage of insured home owners = 40% p = 0.4
Selecting 4 home owners (x) ;
x = 0, 1, 2, 3, 4
Using bernoulli;
nCx * p^x * (1 - p)^(n-x)
For X = 0
4C0 * 0.4^0 * 0.6^(4-0) = 0.1296
X = 1
4C1 * 0.4^1 * 0.6^(4-1) = 0.3456
X = 2
4C2 * 0.4^2 * 0.6^(4-2) = 0.3456
X = 3
4C3 * 0.4^3 * 0.6^(4-3) = 0.1536
X = 4
4C4 * 0.4^4 * 0.6^(4-4) = 0.0256
B.) The most likely value for X are 1 and 2 with probabilities of 0.3456 respectively.
C.) probability that atleast 2 of the 4 selected have earthquake insurance ;
P(X ≥ 2) = p(2) + p(3) + p(4)
P(X ≥ 2) = 0.3456 + 0.1536 + 0.0256
P(X ≥ 2) = 0.5248

answer : [tex]\frac{29\pi }{30}[/tex]
Step-by-step explanation:
given curves = y = x^2 and x = y^2
we determine the inner and outer radii using the washer method
inner radius = R2(y) = 1 + y^2
outer radius = R1 (y) = 1 + [tex]\sqrt{y}[/tex]
volume of the solid = [tex]\frac{29\pi }{30}[/tex]
