thats the answers at least i think thats for first.
Answer:
1) ∠P, ∠DPR, ∠KPR, ∠RPD
2) x = 111°
3) x = 5
4) m∠3 = 72°
Step-by-step explanation:
1) All of the angles display ∠P, you will noticed this if you go from the first letter point and it goes to ∠P and to the last letter point with only including ∠P.
2) I already solved this one in a different post of yours. Subtract all known values from 180° to get your answer.
3) Use the same principle knowing that all sides of a triangle add up to 180°. Add all of the angles together, set the equation to 180 and solve for x.
4) By the Alternate Exterior Angles Theorem, If a transversal intersects two parallel lines, then alternate exterior angles are congruent. Therfore, m∠6 ≡ m∠2, and we know m∠2. Solve by subtracting 108° from 180° because angles on the same line add up to 180°.

PLEASE HELP DUE IN 5 MINUTES!! NO LINKS! HELP PLEASE!!
Answer:
Step-by-step explanation:
its about 263.08!
====================================================
Explanation:
We'll use this formula
S = (x/360)*A
where,
S = area of pie slice, aka sectorx = central angle in degreesA = area of full circleWe'll plug in S = 85.5 and x = 117 to find solve for A.
S = (x/360)*A
85.5 = (117/360)*A
85.5*(360/117) = A
A = 85.5*(360/117)
A = 263.076923076923 which is approximate
A = 263.08 square meters (choice C)
------------
Side note: As the formula suggests, the x/360 portion is the fractional portion of the full area A. For example, if x = 180 degrees, then x/360 = 180/360 = 1/2, meaning we'll take half of the full circle area to get S.
Use the given sequence to answer this following questions:
1, 6, 11, 16, 21, ...
1. Write a rule for the nth term of the arithmetic sequence. (Do not put any spaces between terms when writing the rule.)
2 find the tenth term.
Given:
The arithmetic sequence is:
[tex]1, 6, 11, 16, 21,...[/tex]
To find:
1. The rule for the nth term of the given arithmetic sequence.
2. The 10th term of the given arithmetic sequence.
Solution:
1. We have,
[tex]1, 6, 11, 16, 21,...[/tex]
Here, the first term is 1 and the common difference is:
[tex]d=a_2-a_1[/tex]
[tex]d=6-1[/tex]
[tex]d=5[/tex]
The nth term of an arithmetic sequence is:
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
Putting [tex]a=1,\ d=5[/tex], we get
[tex]a_n=1+(n-1)5[/tex]
[tex]a_n=1+5n-5[/tex]
[tex]a_n=5n-4[/tex]
Therefore, the nth term of the given sequence is [tex]a_n=5n-4[/tex].
2. We need to find the 10th term of the given arithmetic sequence.
From part 1 it is clear that the nth term of the given arithmetic sequence is:
[tex]a_n=5n-4[/tex]
Putting [tex]n=10[/tex], we get
[tex]a_{10}=5(10)-4[/tex]
[tex]a_{10}=50-4[/tex]
[tex]a_{10}=46[/tex]
Therefore, the 10th term of the given arithmetic sequence is 46.

Answer:
x = 9
y = 3
z = 3
Step-by-step explanation:
Triangle 1 (From the left):
5x + 7x = 13x - 9 (Sum of two interior angles of a triangle is equals to exterior opposite angle)
Grouping like terms we have:
12x - 13x = - 9
x = 9
Triangle 2 (From the left):
30y = 90 (angles at a right angle = 90)
y = 3
Triangle 3 (From the left):
15z + 12z + 36 = 39z
36 = 39z - 27z
z = 36/12
z = 3
You received a coupon in the mail for $15 off any pair of Vans so you decide to go shopping. When you walk into the store you find out that there is a sale and all shoes are 30% off! You find a pair of Vans that you love and they cost $55.
Do you use your $15 coupon or take the 30% discount? Which one is the better deal? Be sure to explain your reasoning.
Answer:
the 30% off is better because 30% of 55 is 16.5 and the coupon is for 15 so the 30% off is better.

Answer:
∠ 2 = ∠ 4 = 83°
Step-by-step explanation:
∠ 2 and ∠ 5 are same- side interior angles and sum to 180° , that is
∠ 2 + 97° = 180° ( subtract 97° from both sides )
∠ 2 = 83°
∠ 2 and ∠ 4 are vertical angles and are congruent, then
∠ 4 = 83°

what is the reciprocal of 24
Answer:
-1/24
Step-by-step explanation:
To find the reciprocal, you swap the numerator and the denominator. In this case, the numerator is 24 and the denominator is 1. Therefore, it would be 1/24. Now all we have to do is make this number negative. This would make it -1/24. Therefore, the reciprocal of 24 is -1/24.

3+2(15-11)
The first thing I did was
Change the (-) to a (+)
2) 2*15 = 30
3) change the 11 to -11
4) 2*11 = -22
5) 3+30+(-22) = ?
Step-by-step explanation:
3 + 2(15 - 11)
Step 1: use distributive property
2 x 15 = 30
2 x -11 = -22
3 + 30 + (-22)
3 + 30 - 22
Step 2: using PEDMAS, add the first two numbers
3 + 30 = 33
33 - 22
Step 3: subtract the last two numbers
33 - 22 = 11
Becky can wash 15 dishes in 5 minutes. How many dishes will she be able to wash in 8 minutes?
Answer:
24 is correct answer
Step-by-step explanation:
its a 5:15 ratio, you are finding 8:x
8/5=1.6-> 1.6 x a5 = 24
Answer:
24 plates
Step-by-step explanation:
If she can wash 15 dishes in 5 minutes you just need to figure out how many dished she can washe in 1 minute. so you are gonna divide 15 by 5 and get 3 because 3 times 5 equals 15. so then that means she can wash 3 plates in 1 minute. so if she washed 15 in 5 in 6 minutes she can wash 18 and in 7 minutes she can wash 21 and in 8 minutes she can wash 24. Your just adding 3 to the 15 for every minute.
PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=
Answers:
a = 2 and b = -4
============================================================
Explanation:
Let's define the three helper functions
f(x) = ax^2 - bh(x) = 6j(x) = 5ax+bwhich are drawn from the piecewise function. The g(x) function will change depending on what the input is.
If x < 1, then g(x) = f(x). If x = 1, then g(x) = h(x)If x > 1, then g(x) = j(x)Since we want g(x) to be continuous at x = 1, this must mean the three functions f(x), h(x), j(x) must have the same output value when the input is x = 1.
Because h(x) = 6 is a constant function, the output is always 6 regardless of the input. Therefore, we want f(x) and j(x) to have 6 as their output when x = 1. Or else, the pieces won't connect.
Plug x = 1 into the f(x) function to get
f(x) = ax^2 - b
f(1) = a(1)^2 - b
f(1) = a - b
Set this equal to the desired output of 6 and we end up with the equation a-b = 6. Solving for 'a' leads to a = b+6.
------------
We'll use the same idea for j(x)
j(x) = 5ax + b
j(1) = 5a(1) + b
j(1) = 5a + b
5a+b = 6
5(b+6) + b = 6 ... plug in a = b+6; solve for b
5b+30+b = 6
6b+30 = 6
6b = 6-30
6b = -24
b = -24/6
b = -4
Which then leads to,
a = b+6
a = -4+6
a = 2
------------
Since a = 2 and b = -4, we go from this
[tex]g(x) = \begin{cases}ax^2-b, \ \ x < 1\\6, \ \ x = 1\\5ax+b, \ \ x > 1\end{cases}[/tex]
to this
[tex]g(x) = \begin{cases}2x^2+4, \ \ x < 1\\6, \ \ x = 1\\10x-4, \ \ x > 1\end{cases}[/tex]
Meaning
f(x) = 2x^2+4 and j(x) = 10x-4
You should find that plugging x = 1 into each of those two functions leads to 6 as the output.
The graph is shown below. Note the red graph f(x) is only drawn when x < 1. Similarly, j(x) is only drawn when x > 1. The orange point represents h(x) which only happens when x = 1. So as the name implies, the piecewise function g(x) is composed of pieces of the three functions f(x), h(x), j(x).
