A school is going on a field trip to a museum. The ratio of men to women to children is 1:3:20 and there are 216 people on this trip. What is the difference between the number of children and adults?

Answers

Answer 1

Answer:The difference between the number of children and adults=153

Step-by-step explanation:

ratio of men to women to children is 1:3:20

Total RATIO = 1+ 3+ 20= 24

Number of men = ratio of men / Total ratio x  Total Number of people on the trip =

= 1/24 x 216= 9 men

Number of women=ratio of women / Total ratio x  Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women

Number of children=ratio of Children/ Total ratio x  Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children

The difference between the number of children and adults will be 180 -27 = 153

a). 6:51

b). 6:30 am

c). 34 minutes

What are the first five terms of the sequence represented by the explicit equation g(n) = 34 - 5n ?

Answers

Answer:

Step-by-step explanation:

Remark

My guess is that what is confusing you is not what you have to do, but why it is disguised as g(n)

What you are doing in effect is setting up a table. You are also not certain where the table starts. And that is a problem. I will start it at zero, but it might be 1.

zero

n = 0

g(0) = 34 - 5*0

g(0) = 34

One

n = 1

g(1) = 34 - 5*1

g(1) = 34 - 5

g(1) = 29

Two

g(2) = 34 - 5*2

g(2) = 34 - 10

g(2) = 24

Three

g(3) = 34 - 5*3

g(3) = 34 - 15

g(3) = 19

Four

g(4) = 34 - 5*4

g(4) = 34 - 20

g(4) = 19

Answer

0      1       2       3      4

34  29     24     19     14

Answer:

Step-by-step explanation:

So sorry if this is wrong i tried

The amount after 5 years is $4,644.74.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P[tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $4000

n = 4

r = 3%

t = 5 years

A = 4000 [tex](1 + 0.03/4)^{20}[/tex]

A = 4000 x [tex]1.0075^{20}[/tex]

A = $4,644.74

Thus,

The amount after 5 years is $4,644.74.

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?

Answers

Answer:

i think 150

Step-by-step explanation:

Answer:  $30.00

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

0.20 x $25.00=$5.00.

$25.00 + $5.00 = $30.00.

A student wrote a list of six consecutive integers. If the sum of the first integer and sixth integer is 1, which integer is the least of the six integers?
A. -2
B. 1
C. 3
D. 5

Answers

Answer:

A

Step-by-step explanation:

The student wrote a list of six consecutive integers.

The sum of the first integer and the sixth is 1.

Let the first integer be represented by n.

Then the subsequent integer will be (n + 1).

Therefore, our sequence is:

n, n + 1, n + 2, n + 3, n + 4, and n + 5.

The sum of the first and sixth is 1. Therefore:

[tex](n)+(n+5)=1[/tex]

Solve for n. Combine like terms:

[tex]2n+5=1[/tex]

Thus:

[tex]2n=-4[/tex]

And:

[tex]n=-2[/tex]

Thus, our first term is -2.

Therefore, our sequence is:

-2, -1, 0, 1, 2, 3

The least of the six integers is -2.

Our answer is A.

A

Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets less then Elian. Let A be the number of tickets Alberto won and e be the number of tickets Elian won.

Answers

Answer: See explanation

Step-by-step explanation:

Number of tickets Elian won = e

Number of tickets Alberto won = A = e - 10

Therefore, Elian + Alberto ticket = 100

e + (e - 10) = 100

2e - 10 = 100

2e = 100 + 10

2e = 110.

e = 110/2

e = 55

Elina has 55 tickets

Alberto has 55-10 = 45 tickets
