the percentage of boys in a school is 60%, and the number of girls are 200, calculate the number of boys and the total number of students?

Answers

Answer:

Boys: 300 or 60%, girls: 200 or 40%, total number of students: 500 or %100

Step-by-step explanation:

So basically:

1. We know that 60% is boys and we're trying to figure out the exact amount. We know the other 40% (girls) is a total of 200.

2. First take the 40% and half it so we get 20% in order to do that we have to do the same to the 200 girls and half the number into 100. Now we know 20% is equal to 100 students. Given that information we would multiply the 20% by 3 to get the 60% of boys. Now we would also multiply the 100 by 3 and now we have 300.

3. We now know that we have 300 boys and 200 girls. Add them together for the total of students and you get 500.

I hope this helps:)

500
100% - 60% is 200 people
So 40% is 200 people
20% is 100 people and so 100% (full amount) would be 100 x 5 (how do you get from 20 to 100, you multiple by 5 so you do the same to the 100).
Gives you a total of 500

f ( ) = 13

Answers

Answer:

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

I believe 41 would be your answer. Hope this is right and it helped!

Write an equation of the line in standard form with integer coefficients. the line through (-2, 2), (1, -4). O A. y+2x=-2 B. y+2x=6 C. 2y+x=2 D. 2y+x=-6

Answers

Answer:

Step-by-step explanation:

K=(y1-y2)/(x1-x2)=(2+4)/(-2-1)=-2

y=-2x+b

2=-2*-2+b

b=-2

y=-2x-2

y+2x=-2

The equation of the line in standard form with integer coefficients is → y + 2x = - 2.

What is the general equation of straight line?

The general equation of straight line is -

y = mx + c

where 'm' represents the slope of the line and 'c' is the y - intercept.

Given is a line that passes through the points -

(-2, 2), (1, -4)

We can calculate the slope of the line using the two coordinates given -

(-2, 2), (1, -4). The slope will be -

m = (- 4 - 2)/(1 + 2)

m = -6/3

m = - 2

Assume that the equation of line is -

y = -2x + c

The line passes through the point (-2, 2), so we can write -

2 = -2 x -2 + c

2 = 4 + c

c = -2

So, we can write the equation of line as -

y = - 2x - 2

y + 2x = - 2

Therefore, the equation of the line in standard form with integer coefficients is → y + 2x = - 2.

Find the 62nd term of the arithmetic sequence -27, -21, -15

Answers

it’s 339 if u keep adding 6 until the 62th term

The 62nd term of the arithmetic sequence -27, -21, -15 is 339

Arithmetic sequence

The nth term of an arithmetic sequence is expressed as:

Tn =a+(n-1)d

Given the sequence -27, -21, -15

a is the first term = -27

d is the common difference = -21 + 27 = 6
n = 62

Substitute

T62 = -27 + (62-1)(6)
T62 = -27 + 61(6)

T62 = -27 + 366
T62 = 339

Hence the 62nd term of the arithmetic sequence -27, -21, -15 is 339

C)Advertising on school buses is gaining popularity, but has a long way to go before being widely accepted by the public. D)Advertising on school buses is one way for school districts to make money, and the community may experience benefits as well.(THE PARAGRAPH)18 School buses are carrying more than students these days.19 The vehicles sport fancy advertisements for local businesses and events.20 It's part of the effort for school districts to make money in these budget-strapped times.21 And it is paying off.22 Lewis-Palmer School District 38 made about $8,000 in its first effort last year with eight advertisers and 11 buses. This year, it is expanding.23 "Ultimately we hope to have advertisements on every bus to maximize our income," said Robin Adair, D-38 spokeswoman. The district, which has had $11 million in cuts in recent years, is seeking a $4.5 tax increase in the November election.24 D-38 has 56 buses that collectively travel more than a half million miles a year. That could be a lot of bang for the advertising buck, and a nice amount of change for district coffers. Like Lewis-Palmer, most districts that allow advertising on their buses choose to put the money in general funds to help with such things as higher fuel and utility expenses and increased contributions to pension funds and student activities.25 Other Pikes Peak districts that use their buses as rolling billboards are Colorado Springs School District 11 and Falcon School District 49.
