D = 6sqrt3
In a 45,45,90 triangle the hypotenuse is (x)sqrt2 while the side lengths are equivalent being a single value x. Therefore, when given the hypotenuse and solving for the leg, divide 4 by sqrt2 to get 4sqrt2/2 which simplifies to 2sqrt2 when the denominator and numerator cancel.
In a 30,60,90 triangle the short leg x is across from the 30 degree angle meaning the angle across from the 60 degree angle is x times the sqrt of 3. Therefore the long leg is 6sqrt3

Answer: a = 45°
Step-by-step explanation:
The measure of∠PSR is given: 90°
Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.
The total of all angles in a triangle is 180. So subtract 90, then divide by 2.
180-90 = 90
90/2 = 45
a = 45°
If "b" is supposed to be the measure of ∠SRQ, that is 15° The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15

7.5 cups of sugar to make 14 dozen cookies. To the nearest hundredth, what is the rate of cups of sugar per cookie?
Answers
Answer:
0.54 There you go!
There are 168 cookies. 14 times a dozen (12) is 168.
The ratio of cups of sugar to cookies is 7.5 to 168.
If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.
168/168=1
7.5/168 is about 0.04.
The cups of sugar you use for one cookie is 0.04.

In Exercises 27 and 28, find the domain of the function
represented by the graph. Determine whether the
domain is discrete or continuous. Explain.
Answers
Question 27
The graph on question 27 indicates that there are three points with the locations such as:
(2, 6)(4, 12)(6, 18)In other words, there are three points that lie on the graph with the x-values such as:
{(2, 6), (4, 12), (6, 18)}
We know that the domain includes the set of x-values.
Hence, the domain of the function is:
Domain: {2, 4, 6}Since the points are not connected between them. In other words, there is not a continuous line.
Thus, the function represented on the graph has a discrete domain.
Question 28
The graph on question 27 indicates that the line segment with the end-points (0, 25) and (7, 20).
Since there is a continuous line between the points from x = 0 to x = 7.
Thus, the domain of the line function is:
Domain: {0, 1, 2, 3, 4, 5, 6, 7}As the line segment is a continuous line. Thus, the domain is continuous.

Step-by-step explanation:
Angles APD, DPC and CPB are supplementary. (Angles on a straight line)
Therefore Angle APD + Angle DPC + Angle CPB = 180°.
Since Angle DPC = 90° (Right angle),
Angle APD + Angle CPB = 180° - 90° = 90°.
=> (7x + 1) + (9x - 7) = 90
=> 16x - 6 = 90
=> x = 6
Hence arc measure of minor arc AD

What's the midpoint of a line segment joining the points (5, –4) and (–13, 12)?
Question 8 options:
A)
(–4, 4)
B)
(9, 4)
C)
(–4, 8)
D)
(4, 4)
Answers
Answer:
The midpoint of the line segment is located at (-4, 4).
Step-by-step explanation:
We're given the coordinate points of a line that can help us find the midpoint.
The midpoint formula for a line is written as:
[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]
Additionally, we are given the coordinate points (5, -4) and (-13, 12). We can use these and label them with the (x, y) system so we can substitute them into the formula.
In math, a coordinate pair is written as (x, y). This is where cos = x and sin = y. If we are given two coordinate pairs, we can label them with the (x, y) system but also incorporating a subscript to distinguish the two x-values from each other as well as the y-values. We do this by turning the two x-values into x₁ and x₂ and the y-values follow the same protocol: y₁ and y₂.
Therefore, we can label our two coordinates:
(5, -4)
x₁ = 5y₁ = -4(-13, 12)
x₂ = -13y₂ = 12Now, we can place these values into the midpoint formula and simplify to find our midpoint.
Recall that the midpoint formula is:
[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]
Therefore, let's substitute these values.
[tex]\displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)\\\\\\\big(\frac{5 + (-13)}{2}, \frac{(-4)+12}{2}\big)\\\\\\\big(\frac{-8}{2}, \frac{8}{2}\big)\\\\\\\boxed{(-4, 4)}[/tex]
Therefore, the midpoint of the line segment is located at (-4, 4), which is Option A.
Answer: Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
(x1 + x2)/2 , (y1 + y2)/2)
(5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)
So the answer would be A)
(-4, 4)
Explanation:
let ( x,y) be the midpoint of the line segment, then x = 5+(-13) / 2 = -8/2 = -4 and y = -4+(12 ) / 2 = 8/2 = 4, the mid point is ( -4,4)

Evelyn is trying to make extra money on her summer vacation from school. She

clearing tables. How much money would Evelyn earn in a week in which she worked
3 hours washing cars and 7 hours clearing tables? How much money would Evelyn
earn in a week in which she worked x hours washing cars and y hours clearing
tables?
Answers
Answer:
Washing Cars: $33
Clearing Tables: $91
Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!
Step-by-step explanation:
for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,
11 x 3 = 33, so 33 dollars from washing cars
next - 13 x 7 = 91 dollars from house cleaning
add together the amount of each so, 33 + 91 = 124, 124 is the answer.
