11. Members of the student council are conducting a fundraiser by selling school
calendars. After selling 80 calendars, they had a loss of $360. After selling
200 calendars, they had a profit of $600. Write an equation that describes the
relation between y, the profit or loss, and x, the number of calendars sold. How
much profit did they make from selling each calendar? How much would they
have lost if they had sold no calendars?

Answer:

9x-y=-5

Step-by-step explanation:

First, put this equation into slope intercept form (makes it easier)

9x-y=4

subtract 9x from both sides

-y=-9x+4

multiply by -1 on both sides

y=9x-4

Parallel lines have the same slopes, so the second line is y=9x+b (b is a placeholder for the y intercept)

now, find the y intercept

since the line has to go through (-1,-4), plug it into the equation

-4=9(-1)+b

-4=-9+b

5=b

so now the line would be y=9x+5... in slope intercept form. The question asks for the answer to be in standard form.

5 from both sides

y-5=9x

subtract y from both sides

-5=-y+9x

or

9x-y=-5

Answer:

5/9 = 10/16 is not proportional

Step-by-step explanation:

5/8=10/16 (If you simplify you will get 5/8=5/8 which is true)

25/40=10/16 (If you simplify you will get 5/8=5/8 which is true)

15/24=10/16 (If you simplify you will get 5/8=5/8 which is true)

5/9≠10/16 (If you simplify you will get 5/9=5/8 which is not true)

Answer:

a) The ladder reach 19.32 foot up the house

b) The bottom of the ladder is 5.18 foot from the house

Step-by-step explanation:

An illustrative diagram of the scenario is attached below.

From the diagram, we have a right angle triangle with the length of the ladder being the hypotenuse. The opposite indicates how far up the house the ladder reach and the adjacent indicates the distance of the bottom of ladder from the house.

a) To determine how far up the house the ladder reach, that is the opposite.   Let the opposite be y

From the formula

Sinθ = Opposite / Hypotenuse

Where θ is the angle subtended

Here θ = 75°

Hypotenuse = 20 foot

∴ sin75° = y / 20

y = 20 × sin75°

y = 20 × 0.9659

y = 19.32 foot

Hence, the ladder reach 19.32 foot up the house.

b) To determine how far from the house the bottom of the ladder is, that is the adjacent. Let the adjacent be x

From the formula

Cosθ = Adjacent / Hypotenuse

Where θ is the angle subtended

Then,

cos75° = x / 20

∴ x = 20 × cos75°

x = 20 × 0.2588

x = 5.18 foot

Hence, the bottom of the ladder is 5.18 foot from the house.

y=-3x-3

Step-by-step explanation:

Slope is rise/run, so finding slope is looking at y/x of the lines in between two points.

Then finding the y-intercept you look along the y-axis where the line passes through and what the value there is (look out for positive or negative!).

Answer:

Step-by-step explanation:

Calculator 60 divided by 7.55= 7.94 round to 8

The amount of time Stan works to earn $160 will be 7.94 hours.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Stan earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday evenings. He earned $160 in all.

The working time will be calculated by making an equation assuming the working time to be x hours.

7.55x + 100 = 160

7.55x = 160 - 100

7.55x = 60

x = 60 / 7.55 = 7.94 hours.

Therefore, the amount of time Stan works to earn $160 will be 7.94 hours.

Answer:

40 + 2x = 180

Step-by-step explanation:

Since it is an isosceles triangle, there will be 2 angle x's and all angles will equal to 180 degrees, therefore the equation that will help with finding the measurement of angle x is 40 + 2x = 180.

The ratio which is equivalent to 33:39 is 11:13

An equaivalent ratio are fraction whose value are equal and are integral multiples of each other.

For example 1:2 = 2:4

Since 1:2 = 1 × 2 : 2 × 2 = 2 : 4

Also, 2:4 = 2 ÷ 2: 4 ÷ 2 = 1 : 2

We see that 1:2 and 2:4 are equivalent since we multiply 1:2 by 2 to get 2:4 or divide 2:4 by 2 to get 1:2.

So, to find the ratio equivalent to 33:39, we write 33:39 in its simplest terms.

So, 33:39 = 11 × 3 : 13 × 3

= 11 : 13

So, the ratio which is equivalent to 33:39 is 11:13
