In a day, there are 24 hours. The fractional part of a day you spend sleeping is the ratio of the number of hours you sleep to the total number of hours in a day. This is shown below,
r = 8 hours / 24 hours = 1/3
Thus, you sleep for 1/3 of your day.

The members of a singing group agree to buy at least 250 tickets for a concert. The group buys 20 fewer lawn tickets than balcon

sveta [45]

Answer:

Members of Singing group will buy minimum 135 number of balcony tickets.

Step-by-step explanation:

Given:

Minimum of tickets will be bought =250

Let number of lawn tickets be 'l'.

Also Let number of balcony tickets be 'b'

Now given

The group buys 20 fewer lawn tickets than balcony tickets.

Framing in equation form we get;

$l=b-20$

Now The Sum of Number of balcony tickets and Number of lawn tickets should be greater than or equal to Minimum of tickets will be bought by the group.

Framing in equation form we get;

$l+b\geq 250$

Now substituting the value of 'l' in above equation we get;

$(b-20)+b\geq 250\\\\b-20+b\geq 250\\\\2b-20\geq 250\\\\2b\geq 250+20\\\\2b\geq 270\\\\b\geq \frac{270}{2}\\\\b\geq 135$

Now we know the value of b which is 135 we will substitute in equation $l=b-20$ to find the value of l we get;

$l=135-20 = 115$

Hence Members of singing group will buy minimum 135 number of balcony tickets.

2X+15= -3x how do you work this equation

Sphinxa [80]

Answer: $x=-3$

Add 3x to both sides

$2x+15+3x=-3x+3x\\5x+15=0$

Subtract 15 from both sides

$5x+15-15=0-15\\5x=-15$

Divide both sides by 5

$5x/5=-15/5\\x=-3$

Simplify each expression as much as possible, and rationalize denominators when applicable. √72=?

Misha Larkins [42]

Answer:

6√2

Step-by-step explanation:

Solving the given expression step by step:

72 = 2 × 2 × 2 × 3 × 3

Now for finding the square root we will make pair of two numbers of same values.

We have one pair of 2's and one pair of 3's and left one 2

Thus, √72 = 2 × 3 × √2 = 6√2

We rationalize denominator and change it into a simpler form as soon as possible.

Which one would the equation be?

aleksley [76]

Answer:

a. $y = \frac{2}{5}x - 6$

Step-by-step explanation:

The slope-intercept form of equation of a line is given as $y = mx + b$ . Where,

m = slope

b = y-intercept.

Rewrite the equations, $2x - 5y = 12$ and $4y + 24 = 5x$ , in the slope-intercept form by making y the subject of the formula. Then, derive our new equation that has the same slope as the first equation, and the same y-intercept as the second equation.
