The sum of the interior angles of a polygon is given by the formula s=180(n-2), where s is the sum and n is the number of sides.
In this case, the polygon has 6 sides, so s=180(6-2) or s=180×4, which equals 720.
To work out x, subtract all the other values from this amount, so x=720-90-105-130-145-115, or x=720-585. This equals 135°, so the answer is B.

The population of a city increases by 15% every year. If its population today is
200,000, write an equation that shows where its population will be in 2 years?
Answer:
Step-by-step explanation:
P=200000
P x .15 =x (30000)
2x=y (60000)
P + y= (200000+60000) 260000
Answer:
The equation is :
[tex]A = 200000 ( 1 + 0.15)^2[/tex]
Step-by-step explanation:
Let population in 2 years be A
Current population be P = 200,000
Rate of increase, r = 15% = 0.15
Time, t = 2years
Therefore,
[tex]A= P(1 + r)^t[/tex]
[tex]A = 200000 ( 1 + 0.15)^2[/tex]
[tex]=264500[/tex]
Population after 2 years will be 264,500

Next, verify that point C divides the line in the ratio required by using the distance formula to calculate AC and CB. Show your work.
Answer:
The ratio of AC : CB is 2 : 3
Step-by-step explanation:
Calculate AC and CB using coordinates A (1, 1), B(5, 3), and C(2.6, 1.8) and the distance formula:
Using distance formula, it is found that the ratio of AC : CB is 2 : 3
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²] units.
Calculate AC and CB using coordinates A (1, 1), B(5, 3), and C(2.6, 1.8) and the distance formula:
AC = √[(2.6 -1)² + (1.8 - 1)²]
AC = √[(1.6 )² + (0.8)²]
AC = 2√(0.8)
Similarly, CB = √[(2.6 -5)² + (1.8 - 3)²]
CB = 3√(0.8)
Therefore, the ratio of AC : CB is 2 : 3

Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them.
What is the probability that she pulled out a red marble first and a yellow marble second? Express your answer in decimal form, rounded to the nearest hundredth.
0.09
0.13
0.25
0.32
Answer:
It's the second option, 0.13.
Step-by-step explanation:
Step 1 : Find how many marbles there are in the bag all together.
4 + 4 + 12 = 20 marbles all together
Step 2 : Find what the probability of choosing a red marble is first.
4 red marbles out of 20 marbles =
[tex]P_{1} = \frac{4}{20}[/tex]
Step 3 : Find the probability of choosing a yellow marble now.
Since one red marble was already taken, there are less marbles in total.
Instead of 20 marbles now there are only 19 marbles.
There are 12 yellow marbles out of 19 marbles =
[tex]P_{2} = \frac{12}{19}[/tex]
Step 4 : To get the probability of both of these events happening, we multiply the 2 probabilities.
[tex]\frac{4}{20}[/tex] · [tex]\frac{12}{19}[/tex] = [tex]\frac{12}{95}[/tex]
Step 5 : Express your answer as a decimal.
12 ÷ 95 = 0.12631578947
Rounded to the nearest hundreth that's 0.13.
It's the second option, 0.13.
Hope this helps, please mark brainliest if possible. Have a nice day. :)
The probability of choosing a red and then a yellow marble is 0.13.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
It is given that Lola pulls two marbles from a bag containing four red marbles, four blue marbles, and 12 yellow marbles without replacing them.
That means that there are a total of 4+4+12=20 marbles.
Now to find the probability that she pulled out a red marble first and a yellow marble second.
The probability of choosing a red marble out of 20 marbles is:
P = 4/ 20
The probability of choosing a yellow marble on the second draw is:
P = 12/19
Hence, the probability of choosing a red and then a yellow marble is:
P = 4/ 20 x 12/19
P = 0.13
Hence, the probability of choosing a red and then a yellow marble is 0.13.

How many outcomes are in the sample space when rolling a standard number cube and spinning a spinner with 4 equal sections?
Answer:
There are 24 outcomes in the sample space.
Step-by-step explanation:
Suppose that we have some events, such that each one of these events has a given number of outcomes.
If we have an experiment where we perform all of these events, the total number of possible outcomes is equal to the product between the number of outcomes for each one of the events.
Let's apply this to our case.
Here we have two events:
Rolling a standard number cube: 6 outcomes
Spinning a spinner with 4 equal sections: there are 4 outcomes.
Then the total number of outcomes in the sample space is the product:
C = 6*4 = 24 outcomes.
There are 24 outcomes in the sample space.

The two congruent angles in an isosceles triangle measure 3X + 10o and 5X - 16o . What value of X makes this relationship true?
The value of x will be equal to 13 degrees.
What is a congruent angle?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.
Angles that are identical to one another are referred to as congruent angles. As a result, these angles have the same measure as one another.
Given that the two congruent angles in an isosceles triangle measure 3X + 10 and 5X - 16.
The value of x will be calculated by equating the two angles.
3X + 10 = 5X - 16.
5X - 3X = 16 + 10
2X = 26
X = 26 / 2 = 13
Therefore, the value of x will be equal to 13 degrees.

Step-by-step explanation:
Mathematically, a unit circle is one in which the value of the radius is 1 unit
Generally, for a unit circle we have it that;
r^2 = x^2 + y^2
where (x,y) represents the coordinates of a point on the unit circle
But from above, r = 1
Thus:
x^2 + y^2 = 1
Looking at option C, by squaring each coordinate, we have
(6/7)^2 = 36/49 and the second as 13/49
by adding both, we have
36/49 + 13/49 = 49/49 = 1
Thus, we have this as a coordinate on the unit circle
For the last option;
(5/13)^2 = 25/169 and (12/13)^2 = 144/169
Adding both, we have;
25/169 + 144/169 = 169/169 = 1
So this is also a point on the unit circle
If p= 2q^3-1, what is the value of q when p is 13
a) ∛6
b) ∛7
c) ∛14/2
d) 4393
PLS HELP QUICKLY OMG TYSM
Answer:
b) ∛7
Step-by-step explanation:
If p= 2q^3 - 1, what is the value of q when p is 13
Hence:
13 = 2q³ - 1
We add 1 to both sides
13 + 1 = 2q³ - 1 + 1
14 = 2q³
We divide both sides by 2
14/2 = 2q³/2
7 = q³
q³ = 7
We take the cube root of both sides
∛q³ = ∛7
q = ∛7
Option b is the correct option

Given ix) = 17 - x2, what is the average rate of change in f(x) over the interval [1, 5]?
======================================================
Explanation:
Plug in x = 1
f(x) = 17-x^2
f(1) = 17-1^2
f(1) = 17-1
f(1) = 16
Repeat for x = 5 to find that f(5) = -8
Now we'll use the formula below to find the average rate of change from x = a to x = b.
[tex]m = \frac{f(b)-f(a)}{b-a}\\\\m = \frac{f(5)-f(1)}{5-1}\\\\m = \frac{-8-16}{4}\\\\m = \frac{-24}{4}\\\\m = -6\\\\[/tex]
The average rate of change is -6
The formula is basically the slope formula, more or less. So that's why I used 'm' to represent the average rate of change.
The average rate of change on the interval [1,5] is the same as finding the slope through the lines (1, 16) and (5, -8)
