The graph represents the rate at which Marlo makes origami birds for a craft fair. The equation y = 2.5x represents the number of birds, y, Josh makes in x minutes. Who makes birds at a faster rate? Convince Me! If you were to graph the data for Josh and Marlo on the same coordinate plane, how would the two lines compare? A graph shows time in minutes on the x axis and number of birds on the y axis. the graph is titled Marlo's Rate. The line starts at (0,0) and goes through (40,8).
Answer:
3.0
Step-by-step explanation:
The slope of a graph is the rate of the graph
Josh makes birds at a faster rate.If you graph the data for Josh and Marlo on the same coordinate plane, Josh's graph will have a steeper lineJosh's equation is given as:
[tex]\mathbf{y = 2.5x}[/tex]
A proportional equation is represented as:
[tex]\mathbf{y = mx}[/tex]
Where m represents the rate.
So, by comparison:
[tex]\mathbf{m = 2.5}[/tex]
The points on Marlo's graph are:
[tex]\mathbf{(x,y) = (0,0)(40,8)}[/tex]
So, the rate is calculated as:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m = \frac{8 - 0}{40 - 0}}[/tex]
[tex]\mathbf{m = \frac{8}{40}}[/tex]
[tex]\mathbf{m = 0.2}[/tex]
So, we have:
[tex]\mathbf{m = 2.5}[/tex] --- Josh
[tex]\mathbf{m = 0.2}[/tex] --- Marlo
2.5 is greater than 0.2
Hence, Josh makes birds at a faster rate.
If you graph the data for Josh and Marlo on the same coordinate plane, Josh's graph will have a steeper line

You may determine the slope of the line by determining the rise and the run using two of the line's points.
What is Slope of the line?A line's slope is the change in y coordinate in relation to the change in x coordinate. The net change in y-coordinate is denoted by y, while the net change in x-coordinate is denoted by x. Where "m" represents the slope of a line. As a result, tan represents the slope of a line. Calculate the difference in y-coordinates between these two points (rise). Determine the x-coordinate difference between these two points (run). Divide the y-coordinate difference by the x-coordinate difference (rise/run or slope). The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).Therefore,
You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. Rise divided by Run gives you the slope. Run = rise + slope Rise + run = slope.

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). They sold each ticket for \$70$70dollar sign, 70.
Answer:
Price of each ticket = $70
The revenue generated from sales of 10 tickets = 70 x 10 = $700
After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500
Net Profit = Revenue - Cost
Revenue from n tickets will be = 70n
Cost = $1500
So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

Abigail and Mary are tracking the number of steps they walk. Abigail records that she can walk 6000 steps in 50 minutes. Mary writes the equation = 118, where is the number of steps and is the number of minutes she walks, to describe her step rate. This week, Abigail and Mary each walk for a total of 5 hours. Who walks more steps? How many more?
Answer:
Abigail walks more steps than Mary.
To find out who many steps each one of them walks in a week, we have to carry out different calculations starting with Abigail.
Calculation for number of steps taken by Abigail
Abigail takes 6000 steps in 50 minutes. We can use this information to scale up his number of steps over a period of 5 hours(300 minutes.). The quickest way to do this calculation, is to notice that there are 6 different 50 minute segments in 300 minutes. This means that the number of steps taken in 5 hours is steps.
Another way to do this calculations is to use proportions
.
Abigail takes 36000 steps that week.
Calculation for number of steps taken by Mary
The number of steps taken by Mary is given by the is given by the function where is the time in minutes. Mary walks for a total of 5 hours or 300 minutes. We calculate the number of steps she takes as shown below,
Mary takes a total of 35400 steps.
Since 36000 steps is greater than 35400 steps, we conclude that Abigail walks more steps than Mary.

Sean wants to make a frame for a painting. The painting is square and has area 196 square inches. The framing material costs $1.05 per inch. How much will he spend? You may assume that the framing material buys will be the exact amount needs.
Answer:
$58.80
Step-by-step explanation:
Area = Length * Width square frame length & width will be the same
√196 = 14 inches
196 = 14 * 14
196 = 196
14 inches * 4 sides = 56 inches total needed for frame
Cost:
56 inches * $1.05 = $58.80

Answer:
Step-by-step explanation: Part 1) The units rates are
A)
B)
C)
D)
Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction
Find the unit rate
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
Find the unit rate
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
Find the unit rate
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
Find the unit rate
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
The best buy is the size 48 1/4 oz
