Please help! What is the surface area of the cylinder with height 4 m and radius 8 m? Round your answer to the nearest thousandth.
Make sure to round please.
Answers
The surface area of the cylinder is 948m²
What is surface area of cylinder?The area occupied by a three-dimensional object by its outer surface is called the surface area. The surface of a cylinder is expressed as ;
SA = 2πr(r+h)
Where r is the radius of the base and h is the height of the cylinder.
r =8m
h = 4m
SA = 2 × 3.14 × 8 (8+4)
SA = 78.96 × 12
SA = 947.52 m²
to the nearest whole number
SA = 948 m²

Answer: 1/6
Step-by-step explanation:
To subtract fractions, you must have a common denominator. To do this, the common multiple of 3 and 2 is 6. So 2/3 is multiplied by 2/2 and 1/2 is multiplied by 3/3. The multiplication is valid since we multiplied by one, it didn't alter the value but rather it put it into an alternate, equivalent form.
A bag contains 8items of which two are deffective.A man selects 3 items
Answers
When a man selects 3 items, the probability that they're all defective will be 1/64.
How to calculate the probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.
From the information, bag contains 8items of which two are deffective. The probability of a defective item is:
= 2/8
= 1/4
When a man selects 3 items, the probability that they're all defective will be:
= (1/4)³

A fair die is rolled four times. The probability that each of the final three rolls is at least as large as the roll preceding it may be expressed in the form m/n where m and n are relatively prime positive integers. Find m + n.
Answers
The value of m + n is 53.
Let's consider the first roll "a". The second, third, and fourth rolls will be represented as "b", "c", and "d".
The first roll of a can be any integer from 1 to 6.
For the second roll of b, there are 5 possible integers that are greater than or equal to the first roll "a".
For the third roll of c, there are 4 possible integers that are greater than or equal to the subsequent roll "b".
For the fourth roll of d, there are 3 possible integers that are greater than or equal to the third roll "c".
Thus, the total number of possible outcomes that meet the rules is 6 * 5 * 4 * 3 = 360.
The total number of possible outcomes for rolling a fair die multiple times is 6 * 6 * 6 * 6 = 1296.
This is how the probability of every one of the last three rolls being in some measure as extensive as the roll going before it is 360/1296, which can be improved to 5/18.
In this way, m + n = 5 + 18 = 23.

Set the mean and standard deviation to 0 and 5 , respectively. Approximately 5% of the area under the normal curve lies to the right of 8.2 . Consider what would happen if you were to change the mean to 50 and keep the standard deviation at 5 . Can you predict the new value for which approximately 5% of the area under the normal curve lies to the right of this value? Enter your answer accurate to one decimal place.
Answers
Using z-scores and the normal distribution, it is found that the new value would be of 58.2.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It 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, which is the percentile of X, which is the area to the left of Z under the normal curve.The area to the right of Z is 1 subtracted by the p-value of Z.In this problem:
Mean of 50 and standard deviation of 5, thus \(\mu = 50, \sigma = 5\).Area to the right of 0.05, thus Z with a p-value of 1 - 0.05 = 0.95, thus \(Z = 1.645\).We have to find the value of X, then:
\(Z = \frac{X - \mu}{\sigma}\)
\(1.645 = \frac{X - 50}{5}\)
\(X - 50 = 1.645(5)\)
\(X = 58.2\)

We have,
The formula given is incorrect.
The correct formula for Pythagorean triples with a given integer z is:
(z² - 1², 2z, z² + 1²)
Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:
z² + 1² = 29²
z² + 1 = 29²
z² = 29² - 1
z² = 840
z = √840
z = 28.98
Since z must be an integer, we can try integer values close to 28.98 to find one that works.
Trying z = 29,
a = z² - 1² = 840 - 1 = 839
b = 2z = 58
c = z² + 1² = 840 + 1 = 841
Therefore,
The lengths of the two legs of the right triangle are 58 and 839, in increasing order.

Decide whether the rates are equivalent. Maria saves $50 in 4 months.
Ralph saves $60 in 5 months
Answers
Answer:
The rates are not equivalent since Maria saves $0.50 more per month than Ralph.
Step-by-step explanation:
We can determine if two rates are equivalent by comparing the rates at which they save per month.
Maria's savings per month:
Both 50 and 4 can be divided by 2, which gives us 25/2. As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.
Ralph's savings per month:
Both 60 and 5 can be divided by 5, which gives us 12. Thus, Ralph saves $12 per month.
Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

A 2-yard roll of waxed paper coats $4.02. What is the price per foot
Answers
Answer: $0.67.
Step-by-step explanation:
To find the price per foot of the waxed paper, we need to convert the price from yards to feet and then divide the total cost by the length in feet.
Given:
Length of waxed paper roll = 2 yards
Cost of waxed paper roll = $4.02
1 yard is equal to 3 feet. Therefore, the length of the waxed paper roll in feet is:
Length in feet = 2 yards * 3 feet/yard = 6 feet
To find the price per foot, we divide the total cost by the length in feet:
Price per foot = Cost / Length in feet
Price per foot = $4.02 / 6 feet
Dividing gives us:
Price per foot = $0.67 per foot
Therefore, the price per foot of the waxed paper is $0.67.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~
!Please please show your work!
Answers
Answer:
Slope is -3/7. Y intercept is 250/7.
Step-by-step explanation:
Since they asking for the slope and y intercept, let put it in slope intercept form.
\(y = mx + b\)
where m is the slope and b is the y intercept.
The equation given is in standard form so we will convert it to slope intercept.
\(3x + 7y = 250\)
\(7y = 250 - 3x\)
\(y = \frac{250}{7} - \frac{3}{7} x\)
\(y = - \frac{3}{7} x + \frac{250}{7} \)
The slope is -3/7
The y intercept is 250/7
