"At an ice cream shop, customers pay $3.00 for a medium ice cream plus $0.75 per topping. At a second ice cream shop, customers pay $5.25 for a medium ice cream plus $0.25 per topping. How many toppings would a customer have to order for the ice cream to cost the same at either shop?"
Answer:hope this helps
0.75x + 3 = 0.25x + 5.25
Constants are $3 and $5.25 respectively
Topping costs $0.75 and $0.25 respectively
To have same cost the toppings number would be different as cost is different.
Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:
0.75x + 3 = 0.25y + 5.25
Constants are $3 and $5.25 respectively

An observation deck extends 199 feet out above a valley. The deck sits 149 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h= -16t^2+149. How long will it take for the object to be 5 feet above the valley floor?
Answer:
Step-by-step explanation:
Give the height of the observation deck modeled by the equation
h= -16t^2+149 where t is in seconds;
To get the time it will take the object to be 5 feet above the valley floor, we wil substitute h = 5ft into the modeled equation and calculate t;
h= -16t^2+149
5= -16t^2+149
-16t^2 = 5-149
-16t^2 = -144
t² = 144/16
t² = 9
t = √9
t = 3secs
Hence the time it will take for the object to be 5 feet above the valley floor is 3secs

The Kettings have several bird feeders in their yard. They started with a 10.5 pound of bird seed. After two months, 12 ounces remained. What is the percent of change in the amount of bird seed after two months?
Answer:
Step-by-step explanation: i think its 21.3
The required percentage of the remaining birdseed after two months is 7.14%
Given that, the Kettings have several bird feeders in their yards. They started with a 10.5-pound of birdseed. After two months, 12 ounces remained, what is the percent of change in the amount of bird seed after two months is to be determined
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
In, 1 pound = 16 ounces
Multiply both sides by 10.5,
10.5 pound = 16 * 10.5 ounces
10.5 pound = 168 ounces
Now after 2 months 12 ounces remained
Percentage of the remaining = 12 / 168 * 100
= 7.14%
Thus, the required percentage of the remaining birdseed after two months is 7.14%.

(a - b)(a^2 + ab + b^2)
It should be solved using FOIL
Use the distributive property (of which the FOIL method is a special case):
(a - b) (a² + ab + b²)
= (a - b) a² + (a - b) ab + (a - b) b²
= (a³ - a²b) + (a²b - ab²) + (ab² - b³)
= a³ - b³
Alternatively, you can distribute the quadratic expression over each term in a - b :
(a - b) (a² + ab + b²)
= a (a² + ab + b²) - b (a² + ab + b²)
= (a³ + a²b + ab²) - (a²b + ab² + b³)
= a³ - b³

How can I compare linear relationships?
We have measured simple relationships between the size of different species and their weight (biomass). They are linear regressions (sometimes semilog). The type of question I would like to answer is, for example, if I have 4 species of snail, each with a separate linear equation representing the relationship between size and biomass, are those relationships significantly different, or does one relationship suffice for all my snail species?
I'm not sure how to do this comparison. Each species often has different sample sizes. I thought about just doing the separate relationships, then pooling all samples and comparing the resulting slope to the species-wise relationships with t tests. However I'm worried that species with more samples will bias the results. I could randomly remove samples from those species to equalize them. Another alternative might be to do an ancova with species put in as a dummy variable and look for interactions with species as a test of parallelism. Does that seem reasonable? It seems like a good idea to me because it will also be a test of whether the intercepts are the same.
The approach using a dummy variable and looking for interaction terms will work. It only works for comparing models of the same type (transformed or not). The pooling idea is the start of trying randomization tests (or computer intensive methods in general), but it will not work well if used in the way that you suggest.
The randomization test starts by treating the data as if the null hypothesis was true. One then calculates the probability of withdrawing two samples from your data that have a difference that is equal to or greater than the observed difference. So you resample the data, calculate differences, order these differences, and see how many are equal to or larger than the observed difference. Divide that by the total number of randomizations, and you have your answer.
Answer: Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.

Jesse wants to purchase three binders and a backpack. If the backpack costs $16, which equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase?
The equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Jesse wants to purchase three binders and a backpack. If the backpack costs $16
From the data given in the question:
The linear equation can be framed as follows:
y = 16 + 3x
Or
16 + 3x = y
Thus, the equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.
The options are:
16+y=3x
16+3x=y
y+3x=16
3+16x=y
