Answer: 12.7
Step-by-step explanation:
r=d/2
3.5/2=r
r=1.75
v=pir²h
122.5 =piR²h
122.5=pie1.75²h
The frist thing to solve for r sense exponents come before multiplication in bedmask
122.5 =pi3 .06g
so then it's pie times r
122.5=9.61 *h
122.5/9.61=h
12.7=h

Data set 1: Has a mean of 84 and a MAD of 6. Data set 2 Has a mean of 78 and a MAD of 8 I need to find out what the means to Mean Absolute Deviation (MAD) ratio is.
My teacher keeps telling me that it is 0.75, but I can't seem to get the right formula to it to answer right. can anyone help?
Answer:
0.75 or 6/8
Step-by-step explanation:
This is probably a late answer but I thought I would go ahead and respond.
When you have two data sets with the same variance, the ratio of the means to MAD is a way to test for the pooled variance of the two data sets
Given Data Set 1 with mean M1 and mean absolute deviation with MAD1 and another data set 2 with mean M2 and MAD2 the means to MAD ratio is given by the ratio of the absolute difference in means to the largest of the MADs
Here M1 = 84 and M2 = 78 so the absolute difference is |84-78| = 6
The larger MAD is MAD2 = 8
So the ratio is 6/8 = 3/4 = 0.75

Harrison and Alex are putting a fence around a field that has a perimeter of 384ft. The length is 6ft greater than 2 times the width. Find the width of the field.
a perimeter is made up of a length and width, obviously, so you can write that out algebraically as 2L+2W=P. Now, since the length is 6ft greater than 2 times the width, it can be written as 2W+6. If we plug our new L value in now, we would make the equation 2(2W+6)+2W=P. From here on out, you just gotta plug and chug.
2(2W+6)+2W=P
2(2W+6)+2W=384
4W+12+2W=384
6W+12=384
6W=372
W=62
A fly can walk around a cubical block in two minutes. How long will it take the fly to walk along the edges of the cube from one corner to the opposite corner if it walks at the same rate?
Answer: 90 seconds or 1.5 minutes
Step-by-step explanation: 2 minutes(120 seconds) divided by 4 edges equals 30 seconds per edge. To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds
The time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a fly can walk around a cubical block in two minutes.
The time taken to cover all the one edge is,
T = 120 / 4
T = 30 seconds
To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds. Mathematically written as,
To = 3 x 30
To = 90 seconds
To = 1.5 minutes
Therefore, the time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

Angle B and angle C are supplementary. If the measure of angle B is 14 times the measure of angle C, what is the difference between the angles' measures?
Enter your answer as the correct number of degrees, like this: 42
explain why
Answer:
156
Step-by-step explanation:
Let measure of angle C = x.
Then, the measure of angle B is 14x.
14x + x = 180
15x = 180
x = 12
14x = 14(12) = 168
168 - 12 = 156

What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
What is the quotient?
When two numbers are divided by each other, the result is a quotient. For instance, when we divide 6 by 3, the result is 2, which is the quotient. An integer or a decimal number can be the quotient. We have an integer as the quotient for precise divisions, like 10 5 = 2, and a decimal for erroneous divisions, like 12 5 = 2.4.
As shown in the table, the words- is, gives, and yields will have the equal sign
Another name for subtraction is a difference. Times, product, and multiplication will have the same symbols.

Answer:
19.2
Step-by-step explanation:
[24 + 1.5(16)] / 2.5 = 19.2
Or
[24 - 1.5(16)] / 2.5 = 0
Answer:19.2
Step-by-step explanation:
A gas company charges a $16 monthly service fee and $0.6924 per hundred cubic feet of natural gas used during a month. Which equation best represents Y, the gas company’s monthly charged in dollars for using X hundred cubic feet natural gas?
A. Y = 0.6924x - 16
B. Y = 16x + 0.6924
C. Y = 16x - 0.6924
D. Y = 0.6924 + 16
The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:
Y = 0.6924X + 16
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:
Y = 0.6924X + 16
Now,
Option A has the correct variable coefficients, but the constant term is negative, which is not correct as a monthly service fee is always positive.
Option B has the correct constant term but the variable coefficient is positive, which doesn't make sense as the company charges per hundred cubic feet of natural gas used.
Option C has a similar problem as option A.
Option D has incorrect variable and constant terms.
Therefore,
The correct equation is Y = 0.6924X + 16.
