An interior angle of a regular polygon has a measure of 120°. What type of polygon is it? decagon hexagon quadrilateral octagon
Answers
The answer is Hexagon
The correct answer is B. Hexagon
Explanation:
In geometry, a polygon refers to a figure with three or more sides and therefore at least three angles, this includes triangles, pentagons, octagons, etc. Additionally, polygons can include irregular or regular sides and angles.
In the case of hexagons, if a hexagon is regular, this includes six sides of the same length and six angles with the same measure. Moreover, each of the angles is120° considering the total of internal angles in a hexagon is always 720° and therefore 720° divided into six equal angles is equal to 120°.
Therefore, if an interior angle of a regular polygon (figure with equal sides and angles) has a measure of 120° the polygon is a hexagon because the only polygon that can have multiple sides and angles each with 120° and form a regular polygon is the hexagon.

Due to a leak, the amount of water in a pool is decreasing by 5858 gal every hour.
What is the total change in the number of gallons of water in the pool after 3434 h?
Enter your answer in the box as a simplified fraction.
Answers
Given the the amount of water in a pool is decreasing 5/8 gallon every hour.
And what would be the change in the number of gallons after 3/4 hour. So what we are going to do is just to multiply 5/8 by 3/4. And the result would be 15/32. The total change in the number of gallons of water in the pool after 3/4 hour would be 15/32 gallons.

List the fractors of 35 is this number prime or composite
Answers
Answer: Composite
Step-by-step explanation: To see if 35 is a prime number or a composite number, let's first start by finding the factors of 35.
To find the factors of 35, begin by dividing 35 by 1 which gives us 35. This means that 1 and 35 are factors.
Next, since 35 is not divisible by 2, 3, or 4, we divided 35 by 5 which gives us 7. This means that 5 and 7 are factors.
Next, since 35 is not divisible by 6, we divide 35 by 7 which gives us 5. Notice that 7 and 5 are repeat factors and once we hit repeat factors, this means that all other factors we try will repeat.
Therefore, the factors of 35 are 1, 5, 7, and 35.
Since 35 has more than two factors, it's called a composite number.

.
Use the variable
r
to represent Raj's score.
Answers
product of Raj's score and 6: r x 6
is 66: =66
r x 6 = 66
Final answer:
The sentence 'The product of Raj's score and 6 is 66' translates to the equation 6 × r = 66. By dividing both sides by 6, we find that Raj's score r = 11.
Explanation:
To translate the sentence into an equation, we need to understand the mathematical operation described by the word 'product'.
The product refers to the result of multiplying two numbers.
In this sentence, the product of Raj's score, which we will represent with the variable r, and 6 is given to be 66.
Therefore, the equation representing this relationship is:
6 × r = 66
To solve for Raj's score, you would divide both sides of the equation by 6, which gives you:
r = 66 / 6
Therefore, Raj's score, r, is 11.

Given that segments RS and RT are tangent to circle Q, find the length of RS.
Answers
As they both are tangents of the same circle, their lengths must be equal.
RS = RT
x/4 = x-6.3
x = 4x - 25.2
4x-x = 25.2
3x = 25.2
x = 8.4
As, RS = x/4, it will be equal to 8.4/4 = 2.1
SO, YOUR FINAL ANSWER IS RS = 2.1
To find the length of segment RS, we can use the tangent-radius theorem and the Pythagorean theorem. Segment RS is perpendicular to the radius of circle Q that passes through point S. By using the Pythagorean theorem, we can solve for the length of RS.
Explanation:The length of segment RS can be found using the tangent-radius theorem. According to this theorem, if a line is tangent to a circle at a certain point, then the line is perpendicular to the radius that passes through that point. Therefore, segment RS is perpendicular to the radius of circle Q that passes through point S.
Since RS is perpendicular to the radius, RS and the radius form a right triangle. The length of RS can be found using the Pythagorean theorem. Let's denote the length of the radius as r and the length of RS as x. The radius is the hypotenuse of the right triangle, so we have:
x^2 + RS^2 = r^2
Since RS is the only unknown, we can solve for it. Once we have the value of the radius, we can substitute it into the equation to find the length of RS.

For what values of a and b is the following function is continuous at every x:
-7 x ≤ -3
f(X) = ax-b -3< x < 1
3 x ≥ 1
Find the values is a and b ix f(x) continuous at every x?
Answers
-1 x<=-1
ax-b -1<x<1
2 x>=1
The solution is as follows:
f(x) = {-1, x ≤ -1
...... { ax - b, -1 < x < 1
...... { 2, x ≥ 1
Then we must have:
lim(x-->-1) -1 = lim(x-->-1) ax - b
==> -1 = -a - b
==> a + b = 1
And we must have:
lim(x-->1) ax - b = lim(x-->1) 2
==> a - b = 2
So we need to solve the system of equations given by:
a + b = 1
a - b = 2
After doing so, you should get that:
a = 3/2
b = -1/2
By studying the solution above, you now have the ability to answer the problem on your own!
By solving a system of equations, we will see that the function is continuous for all values of x if:
a = 2.5b = -0.5.How to make the piecewise-function continuous for every x?Here we have the piecewise function:
f(x) = -7 if x ≤ -3
f(x) = a*x- b if -3 < x < 1
f(x) = 3 if 1 ≤ x
The piecewise function will be continuous only if the values at the limits where we have jumps (at x = -3 and x = 1) are the same in both pieces of the function.
This means that we must have:
f(-3) = -7 = a*(-3) - b
f(1) = 3 = a*1 - b
Then we have a system of equations:
-7 = -3a - b
3 = a - b
To solve this, first, we isolate one of the variables in one of the equations, I will isolate b in the second one to get:
b = a - 3
Now we can replace that in the other equation to get:
-7 = -3a - (a - 3)
Now we can solve this for a.
-7 = -4a + 3
-7 -3 = -4a
-10/-4 = a = 2.5
Then the value of a must be 2.5, to get the value of b we use:
b = a - 3 = 2.5 - 3 = -0.5
So the solution is a = 2.5, b = -0.5.

Your $1000 investment in an energy stock doubles. Your $1000 investment in a tech stock drops in half. What was the total return on the two investments?
Answers
Answer: 0.25 or 25%
Explanation:
1) The first stock will double its value ⇒ new value = $1,000 × 2 = $2000
2) The second stock wil dropt to half ⇒ new value = $ 1,000 / 2 = $500
3) Total value of the investments after the change of the values: $2,500 + $ 500 = $ 2,500.
4) Return on investment = benefit / investment
5) benefit = new value - investment = $2,500 - $2000 = $ 500
6) Return on investment = $500 / $2,000 = 0.25

Translate the following statement into an inequality: Five less than a number is at least nine.
Answers
The given statement translates to the inequality x - 5 ≥ 9.
To do this, we first need to interpret ‘a number’ as a variable, which we can call x. ‘Five less than a number’ means we subtract five from our variable, expressed as x - 5. ‘At least nine’ indicates that the value should be greater than or equal to nine, which in inequality form is ( ≥ 9 ). Therefore, the complete inequality that represents the given statement is x - 5 ≥ 9.

Answers
The two points which shows the object traveling at the greatest speed is D. between points A and B because that slope is the steepest
How does this section show the greatest speed ?
The segment between points A and B has the steepest slope, indicating a rapid change in distance over a short period, which implies a higher speed.
This makes sense given the concept of the physics of motion, where a steeper slope on a distance-time graph represents a higher velocity or speed.
Between points C and D has the second greatest speed because it shows that as time went, distance was covered unlike between points B and C.

The circumference of the circle with diameter 6.2 cm, using (pi) equal to 3, is calculated as 18.6 cm using the formula C = (pi)d.
The question asks to calculate the length of the circumference of a circle with a diameter of 6.2 cm, using an approximate value for (pi) as 3. To find the circumference of a circle, the formula C = (pi)d is used, where C is the circumference and d is the diameter. Since we are provided with the diameter (6.2 cm) and an approximate value for
(pi) as 3, the calculation is straightforward.
Using the formula,
C = (pi)dC = 3 * 6.2 cmC = 18.6 cmThus, the circumference of the circle is 18.6 cm.
