Does anyone know the answers to this, I had to do this yesterday but I didn´t know any of the questions.
Answers
Answer:
(A)
(1) NO
(2) YES
(B)
(3) YES
(4) NO
(5) YES
Step-by-step explanation:
According to the triangle sum theorem, the three interior angles of any triangle add up to 180 degrees. So, if we add up the three angles given, to be a triangle, they have to add up to 180 degrees.
38 + 42 + 110 = 190
So, ( (1) 38, 42, 110 ) is not a triangle becuase it adds up to more than 180 degrees (1).
20 + 40 + 120 = 180
So, ( (2) 38, 42, 110 ) is a triangle because it adds up to 180 degrees (2).
For the lengths for a triangle, the length of one side of a triangle must be greater than the difference and less than the sum of the lengths of the other two sides. This is saying:
A-B < C
A+B > C
So to find if they can be, simply plug in the values.
(3)
4-3 < 3
True : 1 < 3
4+3 > 3
True : 7 > 3
(3) is a triangle.
(4)
3-2 < 5
True : 1 < 5
3+2 > 5
False : 5 > 5
(4) is not a triangle
(5)
5-2.5 < 4
True : 2.5 < 4
5+2.5 > 4
True : 7.5 > 4
(5) is a triangle

Doug has a bag full of crayons. There are 6 red crayons, 7 blue ones, and 4 green crayons. Doug wants to color a blue sky. What is the probability that Doug will pull out a red crayon, put it back in the bag, and then get a blue crayon? Write your answer as a simplified fraction
Answers
Answer:
[tex]\sf \dfrac{7}{17}[/tex]
Step-by-step explanation:
Given information:
6 red crayons7 blue crayons4 green crayons⇒ total number of crayons = 6 + 7 + 4 = 17
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
[tex]\implies \sf P(red\:crayon) =\dfrac{\textsf{Number of red crayons}}{\textsf{Total number of crayons}}=\dfrac{6}{17}[/tex]
If the red crayon is put back in the bag, the drawing of the red crayon prior to drawing the blue crayon will not affect the probability of drawing a blue crayon.
[tex]\implies \sf P(blue\:crayon)=\dfrac{\textsf{Number of blue crayons}}{\textsf{Total number of crayons}}=\dfrac{7}{17}[/tex]

What is the change in the breaking weight of the pennies, for each increase in one unit of the length of the bridge?
Answers
Using linear function concepts, it is found that the change in the breaking weight of the pennies was of -6 units of weight.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the function is:
y = -6x + 136.
The slope is of m = -6, hence the change in the breaking weight of the pennies was of -6 units of weight.

If p p and q q vary inversely and p is 17 when q is 4, determine q when p p is equal to 2.
Answers
Answer:
[tex]q = 34[/tex] when [tex]p = 2[/tex].
Step-by-step explanation:
Variables [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another if one variable- for example, [tex]p[/tex]- is proportional to the reciprocoal of the other variable- [tex](1/q)[/tex].
In other words, if [tex]p[/tex] and [tex]q[/tex] ([tex]p \ne 0[/tex], [tex]q \ne 0[/tex]) are inversely proportional to one another, there would exist a constant [tex]k[/tex] ([tex]k \ne 0[/tex]) such that:
[tex]\displaystyle p = k\times \left(\frac{1}{q}\right)[/tex].
The value of [tex]k[/tex] is constant and is independent of [tex]p[/tex] and [tex]q[/tex]. Given that [tex]p = 17[/tex] when [tex]q = 4[/tex], rearrange the equation above to find the value of [tex]k\![/tex]:
[tex]k = p\, q = 68[/tex].
Rewrite the equation again to find [tex]q[/tex] in terms of [tex]k[/tex] (which doesn't change) and [tex]p[/tex] (which might change):
[tex]\begin{aligned}q &= \frac{k}{p}\end{aligned}[/tex].
Since [tex]k = 68[/tex], given that [tex]p = 2[/tex], the value of [tex]q[/tex] would be:
[tex]\begin{aligned}q &= \frac{k}{p} \\ &= \frac{68}{2} = 34\end{aligned}[/tex].

Answers
Answer: BDE
Step-by-step explanation:
Because angles 1, 2, and 3 form a straight angle, x+2x+75=180 -> E
Simplifying, we get that 3x+75=180 -> D
Subracing 75 from both sides, we get 3x = 105 -> B

82.799...°
Step-by-step explanation:
First, we have to identify how many votes equals 1°
Therfore we divide 4700 by 360° because there are a total of 4700 votes and there are 360° in a circle.
(4700/360) = 13.055...
1° = approximately 13 votes
Secondly, let's look at how many votes Watkins received.
1081 votes
Lastly, since 1° equals 13.055... votes,
then if we divide the number of total votes Watkins got by 13.055 we will find the value of the central angle for the Watkins slice.
1081 ÷ 13.055... = 82.7999..

When graphing the equation y=-3x+2, a student plotted the y-intercept at 2, then moved down three units and to the left 2 units because the slope is negative, so both rise and run are negative. Find this error and correct it.
Answers
Answer:
The error is founded in the slope, specifically in the run.
When seen a negative slope, that only applies to the rise but not the run.
Instead, the student should run 1(not 2) units to the right.
The slope had not mentioned any 2 in the run.
So it would sound like down 3, over 1, starting from 2.
The y intercept at 2 is correct. This is the location (0,2)
The slope is -3 or -3/1, meaning that we move down 3 and to the right 1 unit. Doing so has us go from (0,2) to (1,-1). Plot these two points together on the same xy grid and draw a straight line through the two points.
