NEED ANSWERS NOW!!! Solve for x.
Answer:
im not sure i got stuck here ;; but i started sort of
Step-by-step explanation:
The first step is to get the inner angles. I'll start with the one at 60 degrees and call it A and go counter clockwise
A flat angle is 180 and -60 makes it 120 = Angle A
180-100=80=B
180-20=160=C
Then when you're trying to calculate a figure with more than 4 corners, you're supposed to divide them into triangles. Now we have a hexagon and the total degrees is 720. And we know that we have 2 6x and they're the angles
¿Cuál es el resultado de la siguiente operación? -4 +6 -5 +2
help
Answer:
-1
Step-by-step explanation:
[tex](-4 +6)( -5 +2 )\\ - 4 + 6 = 2 \\ - 5 +2 = - 3 \\ 2 - 3 = - 1[/tex]
Answer:
-1
Step-by-step explanation:
Necesitas agregar 6 a 4 negativo, luego obtienes 2, luego restas eso a 5 y obtienes -3 y luego sumas 2 para dejarte con -1.
I put Spanish and English just in case.
You need to add 6 to negative 4 then you get 2 then subtract that to 5 and you get -3 then add 2 to leave you with -1.

Identify the remainder when x3 - 3x2 - 9x is divided by x - 6.
Let p(x) be any polynomial of degree greater than or equal to one and let 'a' be any real number. If a polynomial p(x) is divided by x - a then the remainder is p(a). Hence by the remainder theorem, 0 is the remainder when x3 + 3x2 + 3x + 1 is divided by x + 1.
An item on sale costs 20% of the original price. The original price was $68.
Answer:

Richmond County has a population of 850,000 people, which increases by 10% every year
due to a growing tech industry. What will the population be in 2 years?
If necessary, round your answer to the nearest whole number
Answer:
If the current population is 850,000. Next year it will be 935,000, and the year following that it will be 1,028,500. This is a linear growth (its growth has a common ratio).
Answer:
1,028,500 people
Step-by-step explanation:
When finding the percentage of a number you moved the decimal place over twice and then multiply.
850,000 x 0.10 = 85,000
10% of 850,000 is 85,000
I then found the population of the 1st year
85,000 + 850,000 = 935,000
then I found 10% of that 1st year
935,000 x 0.10 = 93,500
then added 85,000 and 93,500 to find the population growth in the 2 years
85,000 + 93,500 = 178,500
Then added the population growth to the original population
178,500 + 850,000 = 1,028,500 people

Identify the percent of change as an increase or a decrease. Then find the percent of change. Round to the nearest tenth of a percent if necessary.
12 inches to 36 inches
Answer: 200% increase
Step-by-step explanation:
Being an increase from 12inches to 36inches, we will calculate the percentage increase.
%increase = final length -initial length/initial length × 100%
Initial length = 12inches
Final length = 36inches
%increase = 36-12/12 × 100%
%increase = 24/12 × 100%
%increase = 200%
Answer:
200% increase
Step-by-step explanation:
percent change = [(difference between initial and final value) ÷ initial value] x 100
⇒ percent change = [(36 - 12) ÷ 12] x 100 = 200% increase

There were 150 students wearing red shirts today. If there are a total of 300 students at school, about how many out of a class of 30 could be wearing red shirts?
Answer:
I think it's 15 students
Step-by-step explanation:
i think since 150 is half of 300 so in each class there should also be half of the people wearing red
Answer:
150 of 300, 150 is 50 % of 300 so 300/30 = 1 , so I think 15 of the students should be wearing red

A bag of marbles contains 6 blue marbles and 1 green marble. Mary and Frank will draw a blue marble followed by a green marble, without replacing the first marble. Mary says the probability will be 6/49, and Frank says that the probability will be 1/7. Who is correct? Explain and justify your answer by showing work.
---------------Is correct because___
Answer:
Frank is correct, because (see explanation below)
Step-by-step explanation:
Let's separate into two cases:
Case 1: Blue marble
[tex]\frac{6}{7}[/tex] (There are 6 blues in the bag and 7 marbles in total in the bag, we put the 6 in the numerator because we want a blue marble first.)
Case 2: Green marble
[tex]\frac{1}{6}[/tex] (There is only 1 green in the bag and 6 marbles remaining in the bag, because we already took 1 blue out in Case 1. We put 1 in the numerator because we want the green marbloe only.)
Multiply Case 1 with Case 2 because they are a combination:
[tex]\frac{6}{7} * \frac{1}{6} = \frac{1}{7}[/tex]
Therefore Frank is correct.
