Answer:

The answer is 2 and 1/3

Ratio: 7 : 3

Fraction: 2⅓

Translating the word problem into a symbolic statement:  W = kr³/s.  Find k by letting W = 24, r = 4 and s = 8:

         k·4³

24 = --------            

           8

This reduces to 3 = 4^3*k, or 3 = 64k, or k = 3/64 (the constant of proportionality).

       3r^3

w = ---------

         64

Answer:

2√3

Step-by-step explanation:

In a special right triangle called the 30-60-90 triangle, the ratios of the side lengths are x-x√3- 2x respectively. This means that the side opposite to the 60 degrees is x√3 and the side opposite to the 30 degrees is x.

Since the side opposite to the 60 degrees is 6, x√3=6

x√3=6

x=6/√3

rationalize the denominator:

6√3/3

simlify

2√3

so the answer is the third one. 2√3

Answer:

about 5 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

t = 178.25 / ( 650 × 0.05 ) = 5.4846

t = 5.4846 years

The time required to

accumulate simple interest of $ 178.25

from a principal of $ 650.00

at an interest rate of 5% per year

is 5.4846 years (about 5 years 6 months).

Step-by-step explanation:

3x -20= -2x +10

or,5x=30

or,X=30/5

or,X=6

Y= -2×6 + 10

= -2

therefore solution is (6, -2)

Answer: 1/10

Step-by-step explanation:

At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.

Answer:

y=2x-14

Step-by-step explanation:

y=mx+b(m is slope)

we know

y=2x+b

so if you plug in the values for the points you get

-6=4(2)+b

-6=8+b

b=-14

so then the complete equation would be

y=2x-14

Answer:

36 non repeating, 72 repeating (AB=BA)

Step-by-step explanation:

There is a theoretical approach to solving this question. We have formulae for such types of question in ‘Permutation and Combination’ chapter but let me solve it through my approach.

There are 9 members in the unit.

we have to choose only 2 people out of them randomly.

let the members be A, B, C, D, E, F, G, H an, I

A can be chosen first with one of the rest as the second person.

Like AB, AC, AD, AE … AI ………………………(1)

by this, we can choose people in 8 ways.

we will also have 8 ways as BA, CA, DA, … IA ………..(2)

the series (2) is completely reverse of series (1)

now perform the same action taking B as first-person and people after B as the second person.

by this, we will have 7 ways

and 7 ways again in reverse mode.

The same process with C, D, E and other members

we get

8*2 = 16 ways with A

7*2 = 14 ways with B

6*2 = 12 ways with C

5*2 = 10 ways with D

4*2 = 8 ways with E

3*2 = 6 ways with F

2*2 = 4 ways with G

1*2 = 2 ways with H

and I can not be selected lonely because there is no person after I.

SO total ways = 16 + 14 +12 + 10 + 8 + 6 + 4 + 2 = 72 ways

72 will be the answer if the selection of A first and B second is different from the selection of B first and A second.

If AB = BA then the answer will be 72/2 = 36

(It is my approach and easier way for me than the traditional formulae)

Answer:

Step-by-step explanation:

5+4 = 9

8×5 = 40 voted for hot dogs.

The number of campers who voted for hotdogs is 40 campers

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of campers who voted for hot dogs = 5 campers

Let the number of campers who voted for sphagetti = 4 campers

Now , the total campers = 5 + 4

                                        = 9 campers

5 out of 9 campers vote for hot dogs

So ,

The total number of campers = 72 campers

The equation will be ,

The total number of campers who voted for hotdogs =
( number of campers who voted for hot dogs / the total campers ) x 72

The total number of campers who voted for hotdogs = ( 5 / 9 ) x 72

                                                                                        = 5 x 8

The total number of campers who voted for hotdogs = 40 campers

Hence , The number of campers who voted for hotdogs is 40 campers

Answer:

Step-by-step explanation:

A "greater than or equal to" sign means that your line will have a closed, or filled in circle. Knowing this, we can eliminate all of the open circle options.

If our numbers are negative, a number "greater than" a negative would be closer to or positive. I would choose the filled in circle pointing towards the right, given this information.

A) To make a decision on where to park depends on

B) Option 1 is most cost effective when the  parking time is ≥ 3hours

while Option 2 is most cost effective when the parking time is ≤ 30 minute

Step-by-step explanation:

A) To make a decision on where to park depends on

B)

lets assume you will be parked for 30 minutes before picking up your friend

For option 1

You will spend $5 and also get a free shuttle to the terminal

For option 2

You will spend $2  

Therefore Option 2 is better

Lets assume you will be parked for 3 hours  before pick up

For option 1

You will spend $5 and also get a free shuttle

For option 2

You will spend ; $2 for the first 30 minutes + $10 for the remaining 2hours 30 minutes

Therefore Option 1 is better.

Option 1 is most cost effective when the  parking time is ≥ 3hours

while Option 2 is most cost effective when the parking time is ≤ 30 minutes
