Answer:
-4/151
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/*x2-x1)
= (3.6 - 4.8)/(2.65 - -42.65)
= (3.6 - 4.8)/(2.65 +42.65)
= -1.2 / 45.3
-4/151

if w/9 = 0.9
w = ?
w/9 is a fraction :D
Answer:
w= 8,1
Step by step:
w/9= 0.9
the 9, instead of dividing in becomes a multiplication, which you will multiply with 0.9, which is the answer
which goes like...
w/9 = 0.9
w = 0.9 x 9 = 8,1
And then we check it if it's true
8,1 / 9 = 0.9

which is the largest number √10, π, 3
Answer:
the square root of ten is the largest number. I found the square root of 10 on a calculator
Step-by-step explanation:
Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

Use the net to find the surface area of the regular pyramid.
Number only. NO UNITS!
Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².

1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

A math team is working through a set of puzzles. The following diagram describes the numbers of puzzles they've started and not yet started.
Answer:2:5
Step-by-step explanation: We can count the equal parts in the diagram to find the ratio of puzzles started to total puzzles, but that ratio is not one of the choices.
To make an equivalent ratio, we multiply both values in the first ratio by the same number. We can also divide both values by the same number.
Identifying the given ratio
6 + 9 = 15
There are 6 puzzles started for every 15 total puzzles.
The answer choices use smaller numbers. Let's create an equivalent ratio by dividing 6 and 15 by the same number.
Creating an equivalent ratio
We can divide 6 and 15 by 3 to get 2 and 5
Yes, the ratio 2:5 is equivalent to 6:15!
The ratio of puzzles started to total puzzles answers is 2:5.

a post office always charges a flat one time fee for any order. one time, michael sent 35 letters and paid 26 dollars. the next time, he sent 18 letters and paid $14.10. how much does the post office charge to send one letter? what is the flat fee?
Answer:
$0.70 per letter, $1.50 flat fee
Step-by-step explanation:
x+18y=14.1 -> x=-18y+14.1
x+35y=26
|
\/
(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7

\/
x+35(0.7)=26 -> x+24.5=26 -> x=1.5

\/
y=0.7
x=1.5
Hope this helps. :)
The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.
How to determine the the flat fee (F) charged by the post officeTo find the cost of sending one letter, we need to determine the flat fee charged by the post office.
Let's denote the flat fee as 'F' and the cost per letter as 'C'.
From the given information, we can set up the following equations:
Equation 1: F + 35C = 26
Equation 2: F + 18C = 14.10
We can solve this system of equations to find the values of F and C.
First, we subtract Equation 2 from Equation 1 to eliminate F:
(F + 35C) - (F + 18C) = 26 - 14.10
17C = 11.90
Now, we divide both sides of the equation by 17 to solve for C:
C = 11.90 / 17
C ≈ 0.70
Therefore, the cost to send one letter (C) is approximately $0.70.
To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:
F + 35(0.70) = 26
F + 24.50 = 26
F = 26 - 24.50
F = 1.50
Therefore, the flat fee (F) charged by the post office is $1.50.

The supervisor of a call center would like to assemble a committee of 8 people from a staff of 15 call center agents
How many different committees can be chosen?
1. 120
2. 6,435
3. 32,432,400 4.259,459,200
Answer:
Number of different committees that can be chosen = 6435
So,option 2 is correct
Step-by-step explanation:
The supervisor wants to assemble a committee of 8 people from a staff of 15 call center agents.
To solve this we will make use of the combination formula which is:
C(n, r) = n!/[r!(n - r)!]
Where n is population (or available number of people who can sit on the committee) and k, the number selected)
In this question, n = 15 and r = 8
So, we have;
C(15,8) = 15!/[8!(15 - 8)!]
This gives;
C(15,8) = 15!/(8! × 7!)
C(15,8) = 1307674368000/(40320 × 5040) = 6435
Number of different committees that can be chosen = 6435
