Find the sum of the first 34 terms to the nearest integer
13,19,25
Answer:
3808
Step-by-step explanation:
Given the sequence: 13,19,25
First Term, a=13
Common Difference, d=19-13=25-19=6
Since we have a common difference, the sequence is an arithmetic sequence.
We determine the sum of any nth term of an arithmetic sequence using the formula:
[tex]S_n=\frac{n}{2}[2a+(n-1)d] \\n=34, a=13, d=6\\$Therefore:\\S_{34}=\frac{34}{2}[2(13)+(34-1)*6]\\=17[26+33*6]\\=17[26+198]\\=17*224\\S_{34}=3808[/tex]
The sum of the first 34 terms is 3808.

A population of 17500 has
5000 children under the age of 10. What is the fraction, in its simplest form, of children under 10?
Answer:
2/7
Step-by-step explanation:
Fraction of children under 10 = 5000 / 17500 (without being simplified).
we can then simplify it to:
50 / 175 = 10/35 = 2/7
Hope this helps.
Please mark brainiest
Answer:
[tex]\frac{2}{7}[/tex]
Step-by-step explanation:
So we know there is a population of 17,500 and 5000 are children under the age of 10. We want to find the the fraction of the children under 10 over the total population in it's simplest form so,
[tex]\frac{5000}{17500} =\frac{500}{1750} =\frac{50}{175}=\frac{2}{7}[/tex]

Step-by-step explanation:
Eight less than a third of a number is the sum of that number and one.
Let the number be x.
That is:
[tex]\frac{1}{3}x - 8 = x + 1\\ \\=> x - \frac{1}{3}x = -8 - 1 \\\\\frac{2}{3}x = -9\\\\x = -9 * \frac{3}{2}\\ \\x = \frac{-27}{2}[/tex]

What is the midpoint of the segment shown below ?
Answer:
The correct answer is a) (6, 3).
Step-by-step explanation:
The midpoint is determined in straight lines by subtracting the larger x-coordinate value and the smaller x-coordinate value. In this case, it is 10 - 2. You earn 8. Then, divide this answer by 2. So, you get 4. Finally, either subtract this from the larger x or the smaller x. You will earn 6. Since you are solving for a straight line, your y-coordinate will be the same as the others. Therefore, A is your answer.
The answer is (6,3)

If two chords in a circle are congruent, then they are
A. perpendicular
B. the same distance from the center of the circle
C. parallel
If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
Both the extreme points of the chords are connected to the circle. Then the two triangles are formed whose two sides are the radius of the circle that is congruent to each other. Then the triangle will be an isosceles triangle.
And the chord length is also congruent. Then the triangles are congruent to each other by SSS postulates.
If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

Which is the graph of g(x)?
Answer:
The last one
Step-by-step explanation:
Answer:
4 is the correct answer, I believe.
Reasoning:
The first line must be graphed with a constant y of 3, and stop before -2. Which it does on all 4 graphs.
The third line must, when extended, pass through point (0, -3). Only graph 1 and 4 follow that criteria, so it is not 2 or 3.
The second line's y-intercept must be 2, as well as begin at -2 and end before 2. Only graph 4 correctly plots this equation.

What is the constant of proportionality in the equation y = StartFraction x over 9 EndFraction?
Answer:
1/9
Step-by-step explanation:
I'm assuming the equation you mean is y = (x/9) -- if so, parentheses aren't really required.
The equation for the constant of proportionality is y=kx. So, we will want to find the value of k, which is the constant. The y and x variables are in both equations already, and there is only the 1/9, which is k.
Therefore, the constant of proportionality is 1/9. We can check this answer by putting 1/9 back into the equation. y = 1/9 (x) or y= x/9.

please help me. how would you change x + 3y = 18 -3x -12y = -75 to eliminate y showing all of the work
Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)

Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)
Distribute
15x -10 = 10 + 6 +2x
Combine like terms
15x -10 =16+2x
Subtract 2x
13x -10 = 16
Add 10
13x= 16+10
13x = 26
Divide by 13
13x/13 = 26/13
x =2
Answer:
x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)
Distribute.
2.5*6x-2.5*4=10+4*1.5+4*0.5x
15x-10=10+6+2x
Combine like terms.
15x-10=16+2x
Add 10 to both sides
15x-10+10=16+10+2x
15x=26+2x
Subtract 2x from both sides.
15x-2x=26+2x-2x
13x=26

Which proportion could be used to determine if the figures represent a dilation? 2/3=5/8, 2/3=8/5, 2/8=5/3, or 2/8=3/5?
Answer:
The answer is A. 2/3 =5/8
Step-by-step explanation:
The proportion that could be used to determine if the figures represent a dilation is 2/3= 5/8. Option A
What is dilation?Dilation is the process of increasing the size of the object without changing its shape and this is with a defined scale factor.
To determine if the figures represent a dilation, we need to compare the ratios of corresponding sides.
The correct proportion to use is the ratio of corresponding side lengths.
Then, we have that the figure;
2/3=5/8
This means that the ratio of corresponding side lengths in the figures is the same, indicating a dilation.

What is the value of y?
Answer:
option a
Step-by-step explanation: y+y=114 (exterior angle property)
2y=114
y =114/2
y = 57
The measure of angle 'y' in the triangle is 57 degrees.
What is the measure of y in the triangle?The figure in the image is a triangle.
From the diagram:
Angle 1 = y degrees
Angle 2 = y degrees
Angle 3 =?
First, we determine the measure of the third angle.
Since the sum of angles on a straight line equals 180 degrees:
Angle 3 + 114 = 180
Angle 3 = 180 - 114
Angle 3 = 66
Now, the total sum of the interior angles of a triangle equals 180 degrees.
Hence:
Angle 1 + Angle 2 + Angle 3 = 180
y + y + 66 = 180
Collect and add like terms:
2y + 66 = 180
2y = 180 - 66
2y = 114
Divide both sides by 2:
y = 114/2
y = 57°
Therefore, y has a value of 57.
Option A) 57° is the correct answer.
