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

Step-by-step explanation:

Answer: Yes, because with each round table, the amount of chair goes up by 5.

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.

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

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

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.

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.

3 to the power of 11

Step-by-step explanation:

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

The horizontal position for the left edge of the image which Joelle should use to center the image = -4.46cm

We have been told that in the question that the horizontal positions to the right of the leftmost edge of the page are positive.

Given

Joelle is working on a school report on a word processor.

She wants to place an oversized image that is 30.51 cm wide so that it appears centered on the page.

The width of the page is 21.59 cm.

Width of the oversized image = 30.51cm

The first step is to subtract the width of the word processor page from the width of the oversized image.

30.51cm - 21.59cm

8.92cm is the space left

Since we have two sides, horizontal positions to the leftmost side and horizontal positions to the right of the leftmost edge of the page.

The next step is we divide 8.92 by 2

= 8.92cm ÷ 2

= 4.46cm

Automatically, the horizontal position for the left edge of the image which Joelle should use to center the image would the negative.

Therefore, horizontal position for the left edge of the image which Joelle should use to center the image = -4.46cm

Answer:

x = 56

Step-by-step explanation:

The sum of a triangle add up to 180, so add all of the angles in the triangle and equate to 180

x + x + 7 + x + 5 = 180

collect like terms to simplify

3x + 12 = 180

subtract 12 on both sides

3x = 180 - 12

3x = 168

divide 3 on both sides

x = 168 ÷ 3

x = 56
