Answer:
R is 51 degrees
P is 51 degrees
Q is 78 degrees
Step-by-step explanation:
This is an isosceles triangle so R and P are the same angle degree.
First set them equal to each other to be (4x+23)=(2x+37) to get x=7.
Substitute X with 7: 4(7)+23=2(7)+37. It will be 51=51.
A triangle is equal to 180 degrees so 51+51 is 102 and 180-102 is 78.

Find the measure of the vertex angle.
Answer:
∠ Y = 34°
Step-by-step explanation:
Since XY = ZY then the triangle is isosceles and the base angles are congruent, thus
∠ X = ∠ Y , that is
6x - 23 = 4x + 9 ( subtract 4x from both sides )
2x - 23 = 9 ( add 23 to both sides )
2x = 32 ( divide both sides by 2 )
x = 16
Thus
∠ Z = 4x + 9 = 4(16) + 9 = 64 + 9 = 73° = ∠ X
Hence
vertex angle Y = 180° - (73 + 73)° = 180° - 146° = 34°

Answer:
If you find the middle of any side of a triangle, you have found its midpoint. From that midpoint, you can construct a line segment to the opposite interior angle. That constructed line from the midpoint of a side to the opposite interior angle is a median.

The answer is s-337=0.6(t-10), but I don't know how the textbook got this answer.
9514 1404 393
Answer:
process: substitute the given point values into the 2-point form of the equation for a line
Step-by-step explanation:
There are more than a half-dozen different forms of the equation for a line. They are useful for different purposes. One of them is the "two-point form".
Using x as the independent variable, and y as the dependent variable, the equation can be written as ...
y -y1 = (y2 -y1)/(x2 -x1)/(x -x1)
where (x1, y1) and (x2, y2) are the two points.
__
Here, your two points are ...
(t, s) = (10, 337) and (30, 349)
Using s in place of y, and t in place of x, these two points go into the formula like this:
s -337 = (349 -337)/(30 -10)(t -10)
Simplifying the fraction, this is ...
s -337 = (12/20)(t -10)
And writing it as a decimal, we get ...
s -337 = 0.6(t -10)
_____
Additional comments
Adding y1 to both sides of the above form gives you ...
y = (y2 -y1)/(x2 -x1)/(x -x1) +y1
This is the form I usually prefer to use, because it can lead directly to slope-intercept form. For this problem, the form shown above gets you to the answer you're looking for.
__
This "two-point form" is an expansion of the "point-slope form", which is ...
y - k = m(x -h) . . . . . . . line with slope m through point (h, k)
where the equation for slope is ...
m = (y2 -y1)/(x2 -x1)
and (x1, y1) is used instead of (h, k).
Answer:
The actual linear equation is s= 0.6t + 331 which can be rearranged to make s-337 = 0.6( t-10 ).
Step-by-step explanation:
Any linear equation has the formula y=Mx + c , where x is the independent variable , y is the dependent variable , m is the slope of the line and c is the y-intercept .
here y is replaced by “s” which stands for speed of sound and x is replaced by “t” which stands for temperature.
To find the slope , we divide gain of “s” by gain of “t “
i.e. [tex]m= \frac{349-337}{30-10}= \frac{12}{20} = 3/5[/tex]
So the slope of the equation is 3/5 Or 0.6
lets plug s=337 and t= 10 into the equation s= 0.6t+ c
[tex]337= \frac{3}{5} (10) + c\\337 = 6 + c\\C= 331\\Hence the equation becomes s= 0.6t+ 331 \\Rearranging the equation , s-331 = 0.6t \\ subtracting 6 from both sides, s-331-6 = 0.6t-6\\S-337 = 0.6 ( t- 10 ) , which is given in your book.\\\\[/tex]
The last line is s-337 = 0.6t - 6 = 0.6(t-10 ) , which is given in your book.

The equation to represent the total cost of printing the calendars is y=500+2.50x.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
1) Given that, the cost of printing is $500, plus $2.50 per calendar.
Let the number of calendars be x and let the total cost be y.
So, the equation is y=500+2.50x
2) Each calendar will sell for $5.00 each.
The total income, y, for selling x calendars.
So, the total income is y=5.00x
Cameron estimates that the math class will sell 200 calendars.
So, the total cost = 5.00×200
= $1000
Now, y=500+2.50x
Substitute x=200 in y=500+2.50x, we get
y=500+2.50×200
y=1000
Hence, option D is the correct answer.
Therefore, the equation to represent the total cost of printing the calendars is y=500+2.50x.

Manuel wants to earn at least $44 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours Manuel could trim trees? Use (t) for the number of hours. Write your answer as an inequality solved for (t).
Given:
Manuel wants to earn at least $44 trimming trees.
He charges $6 per hour and pays $4 in equipment fees.
To find:
The possible numbers of hours Manuel could trim trees.
Solution:
Let t be the numbers of hours Manuel could trim trees.
Earnings of Manuel in one hour = $6
Earnings of Manuel in t hour = $6t
He pays $4 in equipment fees. So, we will subtract this from the income.
[tex]\text{Total earnings}=6t-4[/tex]
Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.
[tex]6t-4\geq 44[/tex]
[tex]6t\geq 44+4[/tex]
[tex]6t\geq 48[/tex]
Divide both sides by 6.
[tex]t\geq \dfrac{48}{6}[/tex]
[tex]t\geq 8[/tex]
Therefore, the required number of hours must be greater than or equal to 8 hours.

You pick a card at random. Without putting the first card back, you pick a second card at random. Card numbers are 2, 3, 4, and 5 What is the probability of picking a 2 and then picking a number greater than 3? (Write your answer as a fraction or whole number.)
Answer:
1/6
Step-by-step explanation:
When trying to calculate the probability of a sequence of events you need to multiply the probability of the first event happening by the probability of the second event happening. There are a total of 4 numbers (2,3,4,5) and only one is a 2. Therefore the probability of the first pick being a 2 is 1/4. Now there are only 3 cards left (3,4,5) and only 2 numbers are greater than 3 so the probability of picking one of these cards is 2/3. Now that we have both of these probabilities we simply multiply them together.
1/4 * 2/3 = 2/12 or 1/6
Therefore, the probability of picking a 2 and then picking a number greater than 3 is 1/6
