Answer:
see explanation
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides )
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540
2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms
4b + 1.5b + 45 = 540 ( subtract 45 from both sides )
5.5b = 495 ( divide both sides by 5.5 )
b = 90
then
2b - 90 = 2(90) - 90 = 180 - 90 = 90
b + 45 = 90 + 45 = 135
[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135
The angles from least to greatest are
90° , 90° , 90° , 135° and 135°

Step-by-step explanation:
You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.

1,125 words/hour
Answer:
18,75 word read/minutes
or :
1,125 word read/hour
Step-by-step explanation:
The unit rate :
= 150 words read : 8 minutes
= 150/1 words read : 8/1 minutes
= 150/1 × 1/8 word read/minutes
= 150/8 word read/minutes

What is the slope?
Answer:
The slope is 4 or 4/1.
Step-by-step explanation:
Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!

PLEASE HELP MEEE ASAP
Step-by-step explanation:
first of all, g(x) has only negative functional result values (y) except for 0.
and a square is always positive.
so, the only possible right answers are the ones that include a minus ("-") sign.
the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).
so, which equation turns an x = 1 into an y = -3 ?
therefore, the right answer must be D.
g(x) = -3x²
it works for both points :
-3 = -3×1² = -3 correct
-3 = -3×(-1)² = -3×1 = -3 correct

Select all of the points which satisfy the linear inequality below.
-2x + 3y > 4
Answer:
x < − 2 + 3 y/ 2 linear inequality for x
y > 4/3 + 2x/3 linear inequality for y
Step-by-step explanation:
The point which satisfies the linear inequality is (-1,5) so option (C) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given inequality,
-2x + 3y > 4
Put (-1,5) into the above inequality,
-2(-1) + 3(5) > 4
2 + 15 > 4
17 > 4 (True) thus (-1,5) will satisfy the inequality.
The rest points are not satisfying the inequality.
Hence " The point which satisfies the linear inequality is (-1,5)".

Determine whether the following statement is always, sometimes, or never true. Explain your reasoning.
Every complex number has both a real part and an imaginary part.
The statement "Every complex number has both a real part and an imaginary part" is always true.
Every complex number is defined as a number of the form "a + bi," where "a" represents the real part and "bi" represents the imaginary part.
The real part "a" is a real number, and the imaginary part "bi" is a multiple of the imaginary unit "i," where "i" is defined as the square root of -1.
Even if a complex number has a zero imaginary part, it is still considered to have both a real and an imaginary part.
In that case, "a" represents the real part, and the imaginary part "bi" becomes zero.
For example, the complex number 3 + 0i is a real number (3) and can be represented as having a real part of 3 and an imaginary part of 0i.
In conclusion, every complex number by definition consists of both a real and an imaginary part, making the statement "Every complex number has both a real part and an imaginary part" always true.

The population density of the city which is the ratio of population size and the land area is 1419 people per square mile.
The initial population = 2496435The percentage increase in population = 7.9%Land Area = 1898 mi²The population of the city on 2015 can be calculated thus :
(1 + percent increase) × initial population (1 + 0.079) × 2496435 = 2693653.365 peopleThe population of a city is calculated using the relation :
Population density = Population / Land Area Population density = 2693653.365/1898 Population density = 1419.21Therefore, the population density is 1419 people per square mile.
