Answer:
Angle 6 = 91 degrees
Step-by-step explanation:
There are several ways you could use to find angle 6.
You could either find angle 5 then 6, 2, then 6, or 4 then 6 as they can all be found using the given angle with different rules.
First, we can find angle 5 using the corresponding angles rule which states that angles in the same corresponding quadrant are equal. That is angles that are in the same corresponding 'section' in their groups of angles at both intersect points. E.g. Angle 5 and 89 are corresponding angles, therefore angle 5 is equal to 89.
From here we can find angle 6 by using the rule that states that angles on a straight line add to 180. Angle 6 and angle 5 make up a straight line together which we know is 180 degrees. Therefore 180 - angle 5 = angle 6
180 - 89 = 91
Angle 6 is 91 degrees.
We also could have done this by first finding angle 2, which in on a straight line with the given angle. Therefore 180 - 189 = angle 2
Angle 2 = 91
Then used the corresponding angle rule to find angle 6. Angle 2 = Angle 6
Angle 6 = 91.
The final way we could have found it is by finding angle 4 first. The opposite angles rule states that opposite angles sharing a vertex are equal. This means that 89 and Angle 4 are equal. From there we can use the co-interior rule which states that angles in the same 'section' between parallel lines are co-interior (Angle 4 and angle 6) and are equal.
Therefore angle 4 = angle 6
Angle 6 = 91

Explanation. slope intercept form is y= mx + b. m represents the slope and b represents the y intercept (the point where the line meets the y-axis). We know that the slope is 1/3 but since the y-point is 0, there is no VISIBLE “b” in the equation. The correct solution is A :)

Answer:
4) 16√3 in²
5) 63 cm²
Step-by-step explanation:
The formula to use in these cases is ...
A = (1/2)ab·sin(θ)
where a, b are the side lengths and θ is the angle between them.
It helps to know the trig functions of the "special" angles used here.
sin(120°) = sin(60°) = (√3)/2
cos(60°) = 1/2
sin(135°) = cos(45°) = (√2)/2
__
4) The external angle at the base is the supplement of 120°, so is 60°. Then the length of the missing segment between the end of the base and the right angle at h is ...
x = (8 in)cos(60°) = (8 in)(1/2) = 4 in
So, the bottom edge of the triangle is 12 in - 4 in = 8 in.
The area is ...
A = (1/2)(8 in)(8 in)sin(120°) = (1/2)64(√3)/2 in² = 16√3 in²
__
5) As in the previous problem, the difference between the given horizontal dimension and the base of the triangle is ...
x = (18 cm)cos(180°-135°) = 18(√2)/2 cm = 9√2 cm
Then the base of the triangle is ...
16√2 cm -9√2 cm = 7√2 cm
The area is then ...
A = (1/2)(18 cm)(7√2 cm)(√2)/2 = 63 cm²

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.

"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?"
Answers
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

Which is the graph of the linear equation x - 2y = 6?
Answers
Answer:
All you have to do is turn x-2y=6 into y=mx+b form. That would mean you need to get y by itself. Subtract x from 6. Then you have -2y=6-x. Now you have to divide both sides of the equation by -2. So then you have -2y/-2 = 6-x/-2. That turns out to y=3-1/2x Which is easier read by: y=1/2x - 3

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?
Answers
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?
Answers
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%.

Kyle had cable television installed in his house. At the time of installation, there was an initial charge of $199 for the cable box and a setup fee of $49. There is a monthly charge of $79 for cable services. His total bill over a certain number of months, m, was $880. Choose an equation that represents the total costs of Kyle's cable installation and monthly charge. Then, choose the number of months he has had cable
Answers
Answer:
The equation is [tex]199+49+79m=880[/tex]
Kyle has had cable for 8 months.
Step-by-step explanation:
Let m denotes number of months cable services have been used.
Initial charge for the cable box = $199
Setup fee = $49
Monthly charges for cable services = $79
Also,
Total bill over a certain number of months, m = $880
Therefore,
[tex]199+49+79m=880[/tex]
Now solve the equation.
[tex]199+49+79m=880\\248+79m=880\\79m=632\\m=\frac{632}{79}\\ m=8[/tex]
That is Kyle has had cable for 8 months.
