Answer:
42 I believe
Step-by-step explanation:
They way I think about it is if you think about one girl there are 6 other girls around her and so on. So 6 times 7 is 42
But it could be a trick question and it only be 7, because a circle doesn't have a definite start place like a line
A newsstand seller sold a total of 68 magazines and newspapers, which brought in a total of
$199 on a certain day. Suppose newspapers are sold at $2 per copy and magazines are sold at $5 per copy. How many magazines were sold on that day
Answer:
21
Step-by-step explanation:
Using inequality to solve this question, we say
Let the total number of newspapers sold be x
Let the total number of magazines sold by y
x + y = 68
Suppose 1x = $2 and 1y = $5, then
2x + 5y = $199
Solving both as a simultaneous equation, we get that
2(68 - y) + 5y = $199
136 - 2y + 5y = $199
136 + 3y = $199
3y = 199 - 136
3y = 63
y = 63/3
y = 21
Then solving for x, we have
x + 21 = 68
x = 68 - 21
x = 47
Therefore, a total of 21 magazines were sold that day

Answer:
53.33% probability he calls a person from school.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is P(call a person from school)?
He has 30 total contacts, of which 16 are from school. So

If g(×)=sin(6x)+3 determine g(15°)
Answer:
g=4/15 or 0.2667
Step-by-step explanation:
g(x)=sin(6x)+3
g(15)=sin(6times 15)+3
15g=sin(90)+3
15g=1+3=4
g=4/15 or 0.2667
The required value of trigonometric function g(×)=sin(6x)+3 at x =15 is 4.
A function g(×)=sin(6x)+3 is given, value of g(15°) is to determine.
These are the equation that contains trigonometric operators such as sin In algebraic operation.
Here,
The function given is g(×)=sin(6x)+3.
to find g(15°) put x = 15 in the trignometric function in order to get the solution.
⇒ g(×)=sin(6x)+3
⇒ x = 15
⇒ g(15) = sin(6 x15) +3
⇒ g(15) = sin°90 + 3
⇒ g(15) = 1 + 3 (sin°90 = 1)
Thus, the required value of trigonometric function g(×)=sin(6x)+3 at x =15 is 4.

In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°, what is the measure of ∠Z?
Triangles EFG and YXZ, in which triangle YXZ is larger than EFG.
{Please look at the comments for the answer}
A) 38°
B) 62°
C) 80°
D) 142°
Answer: A) 38°
Step-by-step explanation:
Given: In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°.
So, m∠F = m∠X = 80°
m∠Y = m∠E = 62°
By angle sum property , the sum of all angles in a triangle is 180 degrees.
In ΔXYZ ,
∠ X + ∠Y + ∠Z = 180°
⇒ 80°+ 62°+ ∠Z = 180°
⇒ 142°+∠Z = 180°
⇒ ∠Z = 180°-142°
⇒ ∠Z = 38°
Hence, the correct option is A) 38°.

the answer is A, 38 degrees

Answer:
Step-by-step explanation:
The first change, the price goes from $4.09 to $3.59.
Beginning price: $4.09
The price decreased to: $3.59
Amount of decrease: $4.09 - $3.59 = $0.50
Percent of decrease: 0.5/4.09 * 100% = 12.2%
The second change, the price goes from $3.59 to $4.09.
Beginning price: $3.59
The price increased to: $4.09
Amount of increase: $4.09 - $3.59 = $0.50
Percent of increase: 0.5/3.59 * 100% = 13.9%
The first change was a decrease of 12.2%, and he second change was an increase of 13.9%. The two percent changes are not the same, and the second percent change is greater.

The system of equations does not have one solution because the lines will eventually intersect.
The name rintinnn dannnathavannenlistinn hann the linell RAUA internant
Answer:
The two lines are coincident (essentially the same line) so every point on the line is a solution. Normally you would say they have infinitely many solutions.
An example of this would be:
y = 2x + 3
2y = 4x + 6
The statement that matches this situation would be D.
Answer:
D. The system of equations does not have only one solution (it has infinitely many) because the lines do not intersect at *only* one point.

The weatherman predicts a 20% chance of rain on Thursday. If it rains, there is a 10% chance that your roof will leak. (If it doesn't rain, of course, your roof is safe.) What is the chance that you will have a leaky roof on Thursday
Answer:
2%
Step-by-step explanation:
Probability of rain, P(R) = 0.2
Probability of leak Given that it rains, P(L|R) = 0.1
Probability of leak Given that it does not rain, P(L|R') = 0
According to Baye's Rule:
P(L) = [P(L|R) * P(R)] + [P(L|R') * P(R')]
P(R') = 1 - P(R) = 1 - 0.2 = 0.8
P(L) = [0.1 * 0.2] + [0 * 0.8]
P(L) = 0.02 + 0
P(L) = 0.02
Hence, probability of a roof leak on Thursday is 0.02 = (0.02 * 100%) = 2%

Consider a sequence given by the formula f(n)=3n-1 starting with n=1. Generate the first 5 terms of the sequence
Answer:
The first 5 terms are 2, 5, 8, 11, 14.
Step-by-step explanation:
You use the formula to find out each term.f(n)=3n-1 starting with n=1. If n=1 that is the 1st term, if n=2 that is the 2nd term, and so on. n means what number term it is. Now to find each term: n=1: f(1)= 3(1)-1= 3-1= 2 The 1st term is 2n=2: f(2)= 3(2)-1= 6-1= 5 The 2nd term is 5n=3: f(3)= 3(3)-1= 9-1=8 The 3rd term is 8n=4: f(4)= 4(3)-1= 12-1= 11 The 4th term is 11n=5: f(5)= 5(3)-1= 15-1= 14 The 5th term is 14So the first 5 terms are 2,5,8,11,14

Which are equivalent expressions?
Check all that are true.
A) a + b + c = 3abc
B) 4x + 8y = 2(2x + 4y)
C) 4x + 8y = 4(x + 2y)
D) 4x + 8y + 12z = 4(x + 2y + 3z)
E) 5x + 10y = 5(x + 2y)
Answer:
B) 4x + 8y = 2(2x + 4y)
C) 4x + 8y = 4(x + 2y)
D) 4x + 8y + 12z = 4(x + 2y + 3z)
E) 5x + 10y = 5(x + 2y)
Step-by-step explanation:
We would assume a value for the variables a, b, c, x, y and z.
Let x, a = 1
Let y, b = 2
Let z, c = 3
A) a + b + c = 3abc
When a = 1, b = 2 and c = 3
Substituting into the above equation, we have;
1 + 2 + 3 = 3(1*2*3)
6 ≠ 3(6)
6 ≠ 18 (not equivalent)
B) 4x + 8y = 2(2x + 4y)
When x = 1 and y = 2
Substituting into the above equation, we have;
4(1) + 8(2) = 2(2*1 + 4*2)
4 + 16 = 2(2 + 8)
20 = 2(10)
20 = 20 (equivalent expression)
C) 4x + 8y = 4(x + 2y)
When x = 1 and y = 2
Substituting into the above equation, we have;
4(1) + 8(2) = 4(1 + 2*2)
4 + 16 = 4(1 + 4)
20 = 4(5)
20 = 20 (equivalent expression).
D) 4x + 8y + 12z = 4(x + 2y + 3z)
When x = 1, y = 2 and z = 3
Substituting into the above equation, we have;
4(1) + 8(2) + 12(3) = 4(1 + 2*2 + 3*3)
4 + 16 + 36 = 4(1 + 4 + 9)
56 = 4(14)
56 = 56 (equivalent expression).
E) 5x + 10y = 5(x + 2y)
When x = 1 and y = 2
Substituting into the above equation, we have;
5(1) + 10(2) = 5(1 + 2*2)
5 + 20 = 5(1 + 4)
25 = 5(5)
25 = 25 (equivalent expression).
