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

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:

A

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

or

y + 2x = - 2

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

Answer:

Step-by-step explanation:

The maximum number of chairs that the librarian can buy is 20

What are mathematics operations?

A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which :

s represents = the number of chairs,

and we simply solve for s.

800 = 320 + 24s  ... subtract both sides by 300

500 = 24s ... divide both sides by 24

20.83 = s

Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.

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

In Passage 1, how does the author compare the issues of tax increases and advertising on buses?A)They are both actions that require safeguards.B)They are both issues of controversy in school districts.C)They are both possible approaches to dealing with budgetary concerns.D)They are both present problems that cannot be ignored by state representatives.(THE paragraph)1 Tight school budgets could soon translate into Missouri school districts selling ad space on yellow school buses.2 Missouri state Rep. T.J. Berry, R-Kearney, says his billHB 224isnt a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.3 Every single school district has had to deal with budget concerns, Berry said last week. And generally speaking, the way they have had to deal with those has been cuts or tax increases.4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.6 There is no such thing as free money, said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. There are real costs to this: the price of selling out your students to advertisers.7 Students dont need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers present a safety problem around school buses that cannot be ignored, the group said in its position paper.9 National studies have shown that anything that diverts a drivers attention from the road can pose a hazard, opponents say.10 And a big yellow bus doesnt distract? Berry asked.11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.12 Berry said the bill would limit the types of advertising that would be allowed.13 The regulations would prohibit ads that contain obscene or sexual material, or messages associated with gambling, tobacco products, alcohol, and political campaigns or causes. The ads could not promote drug use or any illegal activity or antisocial behavior. They cant contain harmful, discriminatory, false, misleading or deceptive messages.14 There are a lot of safeguards being built in, he said.15 Berry emphasized that the space reserved for the ads would be very limited, meaning toward the back of the bus.16 By 2012, nine statesArizona, Colorado, Massachusetts, Nevada, New Jersey, New Mexico, Tennessee, Texas and Utahpermitted advertising on the exterior of school buses, according to the Campaign for a Commercial-Free Childhood. Several, including Missouri, considered it last year.17 The bill made it out of the Missouri House last year but did not clear the Senate, Berry said.

There can be but little rivalry between ours and any manufacturing or navigating community, such as the Northeastern States of the American Union. It must follow, therefore, that a mutual interest would invite good will and kind offices. If, however, passion or the lust of dominion should cloud the judgment or inflame the ambition of those States, we must prepare to meet the emergency and to maintain, by the final arbitrament of the sword, the position which we have assumed among the nations of the earth. We have entered upon the career of independence, and it must be inflexibly pursued. Through many years of controversy with our late associates, the Northern States, we have vainly endeavored to secure tranquillity, and to obtain respect for the rights to which we were entitled. As a necessity, not a choice, we have resorted to the remedy of separation; and henceforth our energies must be directed to the conduct of our own affairs, and the perpetuity of the Confederacy which we have formed.
