the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9 complete the table of costs
Answers
Answer:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99
Step-by-step explanation:
Given:
The above table
Ratio; Polyester Fabric : Silk = 2:9
Required
Complete the above table
Provided that the ratio of the cost of one meter of polyester fabric to the cost of one meter of one silk is 2:9;
To complete rows of polyester fabric
We simply multiply cost by ratio of polyester fabric ratio (2)
To complete rows of silk fabric
We simply multiply cost by ratio of silk fabric ratio (9)
This is as follows:
When length = 2m
Polyester Fabric = 2 * 2 = 4
Silk Fabric = 2 * 9 = 18
When length = 4m
Polyester Fabric = 4 * 2 = 8
Silk Fabric = 4 * 9 = 36
When length = 8m
Polyester Fabric = 8 * 2 = 16
Silk Fabric = 8 * 9 = 72
When length = 11m
Polyester Fabric = 11 * 2 = 22
Silk Fabric = 11 * 9 = 99
Hence, the complete table is as follows:
Polyester Fabric = 4 || 8 || 16 || 22
Silk Fabric = 18 || 36 || 72 || 99

The two boys used all the money in their lunch account on the same day. Which equation could be used to determine the number of lunches each boy was able to purchase with the amount of money they had in their account?
Answers
Answer:
$45.00 divided by $2.25 or $50 divided by $2.50
Step-by-step explanation:
because this would determine the unit rate. Which is how many lunches the had. They had the total of Carlos would get 20 Elijah would also get 20. They would have an even amount of meals the paid for.
Answer: Carlos had 4 day to eat lunch before his money ran out and Elijah also had four day so they both got 8 meal in total.
Step-by-step explanation: it they both got breakfast and lunch each day then that make four day to eat and also just do 2.25 time 5 day of school then divide the sum of what you got by $45 you should get 4 as for Elijah do 2.50 time 5 day of school then divide $50 by what your sum should be and you also get 4 day for him
see watch and learn
2.25 time 5= 11.25
$45 divided by ll.25=4
2.50 time 5=12.5 or 12.50
$50 divided by 12.50=4 too

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Nadia charges $6.50 an hour for babysitting. She babysits 19.50 hours the first week of the month and 19 hours the second week of the month.
Suppose Nadia raises her rate by $0.65 an hour. How many hours would she need to work to earn the same amount of money she made in the first two weeks of the month?
Complete the explanation and give your answer.
Nadia's new hourly rate is $___ .She would need to work ___ hours in the next two weeks to make the same amount she made in the first two weeks.
Answers
Answer:
Her new hourly rate is $7.15. She would need to work 35 hours in the next two weeks to make the same amount she made in the first two weeks
Step-by-step explanation:
6.50+.65=7.15 which is the new hourly rate
19+19.50 to find how many hours in total which is 38.5 hours
you multiply the rate of 6.50 by 38.5 and you get $250.25 in 2 weeks for the old rate.
I just multiplied until I found the amount of hours to make 250.25 with the new rate.
7.15x35=250.25
Answer:
New hourly rate: $7.15
Total number of hours: 35
Step-by-step explanation:
$6.50 per hour:Given Nadia's hourly rate of $6.50:
For the first week of the month, she babysits for 19.50 hours:
$6.50 per hour × 19.50 hours = $126.75 (Week 1)
For the second week of the month, she babysits for 19 hours:
$6.50 per hour × 19 hours = $123.50 (Week 2).
For those two weeks, she worked for a total of 38.50 hours, and earned $250.25.
$6.50 + $0.65 per hour increase:Nadia increased her hourly rate by $0.65, which means that her new hourly rate will be: $6.50 + $0.65 = $7.15 per hour.
Since we need to determine how many hours she needs to work for in the next two weeks to make the same amount as she did in the first two weeks, we could divide her weekly earnings by her new hourly rate for babysitting:
Week 3:Divide Nadia's earnings for week 1 by $7.15:
$126.75 ÷ $7.15 = 17.72 hours
Week 4:Divide Nadia's earnings for week 2 by $7.15:
$123.50 ÷ $7.15 = 17.27 hours
Week 3 + Week 4 hours = 17.72 + 17.27 = 34.99 or 35 hours
If you multiply her total working hours for weeks 3 and 4 by her new hourly rate:
35 hours × $7.15 per hour = $250.25 (This matches her total earnings for Week 1 and 2).
Therefore, Nadia's new hourly rate is $7.15. She would need to work for 35 hours in the next two weeks to make the same amount she made in the first two weeks.

A party planner organized a dinner party. The party planner recorded the height of the candlesticks over time and graphed the relationship.
graph with the x axis labeled time in hours and the y axis labeled height of candlestick in inches and a line going from the point 0 comma 9 through the point 3 comma 7
Find and interpret the slope and y-intercept in this real-world situation.
The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
The slope is negative three halves, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases three halves of an inch every hour.
The slope is 9, and the y-intercept is negative two thirds. The candle starts at a height of two thirds of an inch and decreases 9 inches every hour.

Answers
Answer:
(a) The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
Step-by-step explanation:
You want to find the y-intercept and slope from the given graph of candle height versus time.
Y-interceptThe y-intercept is the point on the y-axis where the graph intercepts the y-axis. This graph has a y-intercept of 9 inches, the height of the candle when it starts burning.
SlopeThe slope of the graph is the ratio of "rise" to "run". Here, we can see that over a period of 3 hours, the candle loses 2 inches in height. That means the slope is ...
slope = rise/run = (-2 in)/(3 h) = -2/3 in/h
This slope means the candle height decreases 2/3 inch every hour.
__
Additional comment
Your problem statement identifies points on the graph as (0, 9) and (3, 7). These are actually the points where we drew the "rise" and "run" lines in the attachment. They are points where the line crosses grid intersections, which are the best choice for finding slope.
The slope can be found algebraically as ...
m = (y2 -y1)/(x2 -x1) = (7 -9)/(3 -0) = -2/3
We find it is often easier to count grid squares.
I had a simalar question where it was the same this but with 8 as the intercept sooooo it's c if ur looking for the answer hope this helps "The slope is negative two thirds, and the y-intercept is 8. The candle starts at a height of 8 inches and decreases two thirds of an inch every hour."

Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

Step-by-step explanation:
The Code of Hammurabi reflected the social hierarchy of ancient Babylonia in that it differentiated punishments based on the social status of the perpetrator and the victim. For example, the code stipulated different punishments for crimes committed by a nobleman versus those committed by a commoner. This demonstrates that ancient Babylonian society was structured into a hierarchy, with different levels of privilege and responsibility assigned based on social status. The Code of Hammurabi, then, serves as a tangible expression of this social hierarchy, showing the ways in which the laws of the land reflected and reinforced existing power dynamics.
