204, 200,196,... find the 31st term
Answer:
31st term = 84
Step-by-step explanation:
Given:
204, 200,196,...
Find:
31st term
Computation:
204, 200,196,...
First term a = 204
Difference d = a3 - a2
Difference d = 196 - 200
Difference d = -4
An = a + (n-1)d
A31 = 204 + (31-1)(-4)
A31 = 204 - 120
A31 = 84

Choose the best description for the real number 34 over 3
We need to know aut rational numbers to solve this problem. The correct answer is C, rational because it is a fraction.
Rational numbers are numbers that can be written as p/q where q is not equal to zero. In this question 34 over 3 can be written as a fraction, 34/3 where 3 is not equal to zero, so we can safely say that 34 over 3 is a rational number. Now for the reasoning part,
34/33= 11.333...
So we can see that the fraction 34/3 is a repeating decimal and not a terminating decimal. Repeating decimal is a decimal where the numbers after the decimal point keep repeating without an ending. Terminating decimal is a decimal in which the decimal terminates at one point. We can see that in this question 34/3 is not a terminating decimal.
Therefore we see that the best description for 34 over 3 is that it is a rational because it is a fraction.So option C is the correct answer.

The second term of an arithmetic sequence is -39. The rule a, = a -1 + 12 can be used to find the next term of the
sequence. What is the explicit rule for the arithmetic sequence?
a, = -51+12(n-1)
O a = -39+12(n-1)
O a, = 12+(-39)(n-1)
O a = 12+(-51)(n-1)
Answer:
A. an = -51+12(n-1)
Step-by-step explanation:
edge quiz
The solution is, the explicit rule for the arithmetic sequence is
a n = -51 + ( n - 1 ) · 12 .
What is Arithmetic progression?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The nth term of AP : a_n = a + (n – 1) × d
here, we have,
given that,
a 2 = -39
a 2 = a 1 + 12
- 39 = a 1 + 12
a 1 = - 39 - 12
a 1 = - 51 ( first term )
The common difference is : d = 12
The explicit rule for the arithmetic sequence:
a n = a1 + ( n - 1 ) d
a n = -51 + ( n - 1 ) · 12
Hence, The solution is, the explicit rule for the arithmetic sequence is
a n = -51 + ( n - 1 ) · 12 .

What value of m makes the equation true? 2(m+1.5)=m+10
Answer:
2(m+1.5)=m+10 m=7
Step-by-step explanation:
Distribute 2 to the m and the "1.5". You get 2m+3
You then drop the m+10 and the equation is 2m+3 = m+10
After that, you subtract the "m" over to the "2m" which becomes m+3 = 10
You then subtract the 3 over to the 10 which finally comes to m=7
Evaluate 3 m + n 2 8 when m = –6 and n = 12.

Answer:
The coordinates of point F would be: (x, y) = (8.2, 5.7)
Step-by-step explanation:
We know that the location of a point P on a coordinate plane can be determined by checking the value of the x-coordinate and the corresponding y-coordinate.In other words, the location of a point P with the x-coordinate and the corresponding y-coordinate will be: P(x, y)
Using the same concept, we can determine the coordinates of point F.The location of point 'F' lies on the x = 8.2 (x-coordinate) and their corresponding value of y=5.7 (y-coordinate).
i.e at x = 8.2, y = 5.7
Thus, the coordinates of point F would be: (x, y) = (8.2, 5.7)

hich correctly explains how to estimate 33 percent of 87?
Round 33 percent to 20 percent and 87 to 80. Think of 20 percent as 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 30 percent of 80 is 8 + 8, which is 16.
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 35 percent and 87 to 90. Think of 35 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 35 percent of 90 is 9 + 9 + 9, which is 27.
Round 33 percent to 40 percent and 87 to 80. Think of 40 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 80 as 8. So, 40 percent of 90 is 8 + 8 + 8, which is 24.

in the diagram, AB is parallel to DE. Also, DE is drawn such that the length of DE is half the length of AB. If sin A=0.5, then what is sin E?
Answer:
I got sin E = 0.5
Thus answer choice C being the correct choice
Hope this helps ;)
Step-by-step explanation:
For given diagram, sin(E) = 0.5
What is transversal?"It is a line that passes through two lines in the same plane at two distinct points."
What are parallel lines?"These are the lines in the plane that are at equal distance from each other and never meet."
For given question,
AB is parallel to DE.
We can observe that, the line segment AE is transversal.
So, ∠DEF and ∠FAB are alternate interior angles.
We know, when a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
⇒ ∠FAB = ∠DEF
⇒ ∠A = ∠E
⇒ sin(A) = sin(E)
As, sin(A) = 0.5
⇒ sin(E) = 0.5
Therefore, sin(E) = 0.5
