Find an angle a that is coterminal with an angle measuring -720°, where 0° < a < 360°.
Step-by-step explanation:
To find an angle that is coterminal with an angle measuring -720°, we need to add or subtract multiples of 360° until we get an angle between 0° and 360°.
We can start by adding 360° multiple times until we get a positive angle:
-720° + 360° = -360° (still negative) -360° + 360° = 0°
So, -720° is equivalent to an angle of 0° plus a full rotation of 360°.
Since we want an angle that is between 0° and 360°, we can just take a = 0°.
Therefore, an angle that is coterminal with an angle measuring -720° and between 0° and 360° is a = 0°.

Answer:
81.75
Step-by-step explanation:
First, find the median of all the answers.
78.25, 77.75, and 84 = 80 (median)
now that we know 80 is the median, we will add it to our solution.
And still, there is no OTHER TEST in to make this stay 80.
78.25, 77.75, 84, and 80 = 79.125
since this is incorrect, we go higher.
78.25, 77.75, 84 and 81 = 79.625
since this is also incorrect, we go higher.
78.25, 77.75, 84 and 82 = 80.125
since this is higher and incorrect, we will go lower to 81.5.
78.25, 77.75, 84 and 81.5 = 79.875
since this is lower AND 82 is not the correct solution, we will go up by 0.25.
78.25, 77.75, 84 and 81.75 = 80
To check, we will do the problem again.
78.25, 77.75, 84 and 81.75 = 80
So, the solution is 81.75

The figure below is a map showing 12 cities and 17 roads connecting certain pairs of cities. Paula wishes to travel along exactly 13 of those roads, starting at city A and ending at city L, without traveling along any portion of a road more than once. (Paula is allowed to visit a city more than once.)
A (0)
B (1)
C (2)
D (3)
E (4)
The number of routes that Paula can take using graph theory is; E: 4
How to find the number of possible routes?We will observe that out of the 12 cities, 6 of them possess 3 edges going in/out of them.
The 6 cities are such that there are 2 at the top, 2 at the bottom, and 1 on each side.
In graph theory terms, we can say that they are of degree 3.
Thus, at least 1 edge connecting to each of these cities cannot therefore be used. Furthermore, the same concept applies to the start and end points, due to the fact that we don't want to return to them.
There are 6 + 2 = 8 vertices that we can tell have 1 unused edge, and then we have 17 - 13 = 4 unused edges to work with due to the fact that we have 17 edges in total, and as such must use exactly 13 of them).
Finally, we notice that at each of the 2 cities marked with an O on a path in the image attached, that there are 2 possibilities such that it's either we continue straight and cross back over that same path later, or we will make a left turn, and then turn rightward when we approach the junction again.
This gives us a total of;

Step-by-step explanation:
Hello!
The topic we should review for this problem is Order of Operations.
What is Order of Operations?
Order of Operations is a rule that identifies which part of an equation should be simplified first.
You might've heard of PEMDAS, where;
P for Parentheses, always first unless there's an exponent inside.
E for Exponent, simplified after the Parentheses.
M or D - Multiplication or Division after the Exponent(s).
A or S - Addition or Subtraction after Multiplication or Division.
\((5+3^2)+18\)
First we know that there's an Exponent inside the Parentheses, so we must evaluate that number first.
\((5+9)+18\)
Next, evaluate what's in the Parentheses.
\(14+18\\32\)
Our correct answer is 32.

if 6 people can walk 12 dogs, how many people are needed to walk 24 dogs
Answer:
12 people are need to walk 24 dogs
Step-by-step explanation:
12/2=6
24/2=12
Answer:
12 people can walk 24 dogs.
Step-by-step explanation:
Given information,
→ 6 people can walk 12 dogs.
→ People required for 24 dogs = ?
Let us assume that,
→ Missing value = p
Forming the equation,
→ 6/12 = p/24
Then the value of p will be,
→ 6/12 = p/24
→ p/24 = 6/12
→ p × 12 = 6 × 24
→ 12p = 144
→ p = 144/12
→ [ p = 12 ]
Hence, the value of p is 12.
LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN= 4x + 3 and MP = 8x -9
X=
Solution:
We know that:
Given diagonals: LN and MPLN and MP must be equal because they are diagonals of LMNP.LN = 4x + 3MP = 8x - 9Since LN and MP must be equation, equation formed: 4x + 3 = 8x - 9
Let's simplify the equation to find x.
Subtracting 4x both sides.
\(4x + 3 = 8x - 9\)=> \(4x - 4x + 3 = 8x - 9 - 4x\)=> \(3 = 4x - 9\)Add 9 both sides.
=> \(3 = 4x - 9\)=> \(3 + 9 = 4x - 9 + 9\)=> \(12 = 4x\)Divide 4 both sides.
=> \(12 = 4x\)=> \(\frac{12}{4} = \frac{4x}{4}\)=> \(x = 3\)Now, let's find the length of each diagonal.
\(LN = 4x + 3 = 4(3) + 3 = 12 + 3 = 15 \space\ units\)\(MP = 8x - 9 = 8(3) - 9 = 24 - 9 = 15 \space\ units\)Diagonals are equal

Use the diagram below to find the given variablesM, N, P, Q, R, S, T U
From The diagram in the question.
Step 1: To find M,
M + 90+ 60 = 180(sum of angle in a triangle)
M + 150= 180
M = 180 - 150
M = 30
Use similar reason,
40+ 90+N = 180
130 + N =180
Therefore, N = 50
Step; Using angle on a straight line
112 + x = 180
x = 180 - 112 = 68
Then, M + X + Y = 180
30 + 68 + Y = 180
98 + y = 180
Y = 180-98 = 82
Note that Y and X are vertically opposite angle
P = 82
Step 3 ;Find q
70 is a vetically opposite angle
p + q + 70 = 180 ( sum of angle in a triangle)
82 + q + 70 =180
152 + q = 180
q = 28
Step4 : To find T ( Note that Y is vertically opposite to T)
N + 68 + Y = 180 ( Sun of angle in a Triangle)
50 + 68+ T = 180
118 + T = 180
T = 180 - 62
T = 118
Step 5 ; Find r
using sum of angles in a triangle
90 + 50 + r = 180
140 + r = 180
r = 40
r is vertically opposite angle
r + s + 70 = 180
40 + s + 70 = 180
110 + s = 180
s = 70°
Step 6; find U
From t, using angle on a straight line
t+ a = 180 + a = 180
118 +a = 180 - 118= 62
s + 62 + v = 180
70 + 62 + v = 180
132 + v = 180
v= 48
then, V is vertically opposite
90 + u + v(vertically opposite) = 180
90 + u + 48 = 180
u = 180 - 138
u = 42°.
Therefore, M = 30°, N = 50°, p= 82°, Q= 28°, R = 40°, S =70°, T =118°, U = 42°

Suppose that in a certain country, 10% of the elderly people have diabetes (call this Event D). It is also known that 30% of the elderly people are living below poverty level (call this Event P), 35% of the elderly population falls into at least one of these categories, and 5% of the elderly population falls into both of these categories. If a randomly selected elderly person is living below the poverty level, what is the probability that she/he has diabetes
Answer:
0.1667 = 16.67% probability that she/he has diabetes
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which
P(B|A) is the probability of event B happening, given that A happened.
\(P(A \cap B)\) is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Living below the poverty level.
Event B: Having diabetes.
30% of the elderly people are living below poverty level.
This means that \(P(A) = 0.3\)
5% of the elderly population falls into both of these categories.
This means that \(P(A \cap B) = 0.05\)
If a randomly selected elderly person is living below the poverty level, what is the probability that she/he has diabetes
\(P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.3} = 0.1667\)
0.1667 = 16.67% probability that she/he has diabetes

Chuck's Chops, an up-scale steak house, received an invoice for 800 pounds of baking potatoes with a cost of $.85 per pound. The terms were, n/30. Chuck was unable to pay the bill in full within the discount period but was able to remit a partial payment of $425.00 within the discount period. How much credit did Chuck receive for his payment?
Chuck received a credit of $369.15 for his partial payment.
What is simple interest?
The interest on a loan or principal sum can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more.
The total cost of the baking potatoes is calculated by multiplying the weight of potatoes by the cost per pound:
800 pounds x $0.85/pound = $680
Since the terms are n/30, Chuck has 30 days to pay the invoice in full to receive the discount. He made a partial payment of $425 within the discount period, which means he has a remaining balance of:
$680 - $425 = $255
To determine how much credit Chuck received for his partial payment, we need to calculate the discount he would have received if he had paid the full amount within the discount period. The discount is calculated by multiplying the total cost by the discount rate, which is calculated by dividing the discount period by the number of days in the year:
Discount rate = discount period / number of days in the year
Discount rate = 30 / 365
Discount rate = 0.0822
Discount = total cost x discount rate
Discount = $680 x 0.0822
Discount = $55.85
Since Chuck only paid $425 within the discount period, he is entitled to a credit for the remaining discount amount:
Credit = Discount - Partial payment
Credit = $55.85 - $425
Credit = -$369.15
Therefore, Chuck received a credit of $369.15 for his partial payment.
