Answer:

3/5 of the crayons are not broken since 2 are broken

The fraction of crayons that are not broken if out of 5 crayons, 2 of them being broken is 3/5

Suppose the fraction is proper (the numerator is smaller than the denominator).

Let it be [tex]\dfrac{a}{b}[/tex]

Then, we can interpret it as:

[tex]\dfrac{a}{b}[/tex]    is "a" parts out of "b" parts of a thing.

Here, we're specified that:

Then we get:

Number of crayons that aren't broken = total crayons - number of broken crayons = 5 - 2 = 3

Thus, 3 out of 5 crayons are not broken.

Using fraction, we write it as:
[tex]\dfrac{3}{5}[/tex]

We pronounce it as "three-fifth of total crayons are not broken".

Thus, the fraction of crayons that are not broken if out of 5 crayons, 2 of them being broken is 3/5

Answer:

  each equation can be transformed to the other

Step-by-step explanation:

Starting with the given equation, we can subtract 4, then multiply by 2:

  x + 5 = 15

  x + 5 - 4 = 15 - 4

  x + 1 = 11

  2(x + 1) = 2(11)

  2(x +1) = 22 . . . an equivalent equation

The properties of equality allow one equation to be transformed into the other.

sin 47° = 950/x

xsin47° = 950

x = 950/sin47°

Answer:

Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;

2y-40 + 40 =-18+40

2y = 40-18

2y = 22

We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.

Dividing the resulting equation by 2:

2y/2 = 22/2

y = 11

The amount of interest Caitlyn will be charged after the first month is $1.875.

Annual percentage rate(APR) of the credit card = 18%

The monthly percentage rate will be 1/12th of APR.

The Amount charged in the first month =$375

Amount paid in billing cycle = $250

So, the amount on which interest will be levied = $375 - $250 = $125

The interest levied on $125 = 125* (18/12)* (1/100)

The interest levied on $125 = $1.875

Therefore, the amount of interest Caitlyn will be charged after the first month is $1.875.

Answer:

the answer is the top right one

The function that gives the amount of profit at a given price and number

given are obtained from the relationship between the variables.

a) The profit in terms of the number of tickets sold, P = -0.015·n² + 250·n

(b) The profit in terms of ticket price, is P = -66.[tex]\overline 6[/tex]·p² + 3000·p + 2,333,333.[tex]\overline 3[/tex]

Reasons:

Number of tickets sold at x = $200, is y = 10,000 tickets

Number of extra tickets sold for every $15 price reduction = 1,000 tickets

Number of tickets sold at $185 = 11,000

The cost to fly a person = $100

(a) The rate of change, [tex]\frac{\Delta y}{\Delta x}[/tex], of the number of ticket sold wit price is given as

follows;

[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{11,000 - 10,000}{185 - 200 } = -66. \overline 6[/tex]

The equation in slope and intercept form is therefore;

n - 11,000 = -66.[tex]\overline 6[/tex]·(p - 185)

n = -66.[tex]\overline 6[/tex]·p + 12,333.[tex]\overline 3[/tex] + 11,000 =  -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]

Number of tickets sold, n = -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]

[tex]Price \ per \ ticket, \ p = \dfrac{23,333.\overline {3} - n}{66. \overline{6}}[/tex]

The revenue, R = n·x

Therefore;

[tex]R = \dfrac{23,333.\overline {3} \cdot n- n^2}{66. \overline{6}}[/tex]

The profit = Revenue - Cost

The cost = 100·n

[tex]Profit, P = \dfrac{23,333.\overline {3} \cdot n- n^2}{66. \overline{6}} - 100 \cdot n = -0.015 \cdot n^2 + 250 \cdot n[/tex]

(b) The total profit, P, in terms of the price p, for one ticket

Number of tickets sold, n = -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]

The revenue, R = n·p

∴ R = -66.[tex]\overline 6[/tex]·p² + 23,333.[tex]\overline 3[/tex]·p

Cost = 100·n

∴ Cost = 100·(-66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex])

Therefore, the profit is given as follows;

Profit = -66.[tex]\overline 6[/tex]·p² + 23,333.[tex]\overline 3[/tex]·p - (100·(-66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]))

We want to express the total profit in two different ways.

The answers are:

a) P(n) = n*[n - 23,333.3]*(-15/1,000) - n*100

b) P(p) =  n(p)*p - n(p)*100 = [ (-1,000/15)*p + 23,333.3]*(p - 100)

The given information is:

a) We want to get the profit in terms of the number n of tickets sold.

The number of tickets sold depends on the price, we know that it is a linear relation like:

n(p) = a*p + b

where p is the price.

we know that:

n(200) = 10,000

n(185) = 11,000

If this is a linear relation, the slope is known:

a = -1,000/15$

Then the line is something like:

n(p) =  (-1,000/15)*p + b

We know that if k = 200, then n = 10,000

Replacing that we have:

n(200) = 10,000 =  (-1,000/15)*200 + b

               10,000 + (1,000/15)*200 = b = 23,333.3

Then the number of tickets sold as a function of the price is:

n(p) =  (-1,000/15)*p + 23,333.3

Then the revenue is given by the number of tickets sold times the price, this is:

r(n) = n*p

We can write k in terms of n as:

k = [n - 23,333.3]*(-15/1,000)

Then the revenue as a function of the number of tickets sold is:

r(n) = n*[n - 23,333.3]*(-15/1,000)

The profit is the difference between the revenue and the cost, then the profit function is:

P(n) = n*[n - 23,333.3]*(-15/1,000) - n*100

Where n*100 is the cost.

b) now we want to write the same equation, but this time as a function of the price.

now the revenue is:

r(p) = n*p = [ (-1,000/15)*p + 23,333.3]*p

Then the profit is:

P(p) =  n(p)*p - n(p)*100 = [ (-1,000/15)*p + 23,333.3]*(p - 100)
