Answer:

Monthly sales = $15000

Step-by-step explanation:

Let x be the monthly sale.

Given:

The monthly salary of a show room attendant is the sum of a fixed  salary of $600 plus 8% of all monthly sales.

8% of monthly sale = [tex]\frac{8}{100}\times mothly\ sale[/tex]

8% of monthly sale = [tex]\frac{8}{100}\times x[/tex]

So, the monthly salary of attendant is.

[tex]Monthly\ salary = 600+8\ percent \ of\ monthly\ sales[/tex]

[tex]Monthly\ salary = 600+\frac{8}{100}\times x[/tex]

Monthly salary is given.

[tex]1800 = 600+\frac{8}{100}\times x[/tex]

[tex]1800 - 600 = \frac{8}{100}\times x[/tex]

[tex]1200 = \frac{8}{100}\times x[/tex]

[tex]x=\frac{1200\times 100}{8}[/tex]

[tex]x=\frac{120000}{8}[/tex]

[tex]x=15000[/tex]

Therefore, the monthly sale is $15000

Answer:

D. (sugar * frosting)/Flour

Step-by-step explanation:

Given that

The formula for sweetness of a cake is represented by S = sf/F

where the

sweetness of a cake is denoted with S

amount of sugar in a cake, with A

amount of frosting, with f

amount of flour with F.

To get the appropriate unit, all we need to do is to substitute the letter representation of each unit with the original word.

So,

S = sf/F becomes

S = (sugar * frosting)/Flour

We arrive at this by replacing s with sugar; f with frosting and F with Flour

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{5}{3}[/tex] x + 5 ← is in slope- intercept form

with slope m = - [tex]\frac{5}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

Answer:

5/3

Step-by-step explanation:

Answer:

the answer is a 18 because that would mean there are more red than any color in the bag

To make the probability of drawing a red marble 1/2 with the current bag of marbles, you would need to add 12 more red marbles.

To answer the question about how many additional red marbles must be added to the 18 marbles already in the bag so that the probability of randomly drawing a red marble is 1/2, we first need to understand how the probability of an event is calculated. Probability is calculated by dividing the number of ways an event can occur by the total number of outcomes. In this case, the event is drawing a red marble and the total number of outcomes is the total number of marbles in the bag.

Currently, there are 6 red marbles and 18 total marbles in the bag, so the probability of drawing a red marble is 6/18 = 1/3. We want this probability to increase to 1/2, so we need to add more red marbles. Let's represent the number of red marbles we need to add as x. To find x, we need to solve the following equation: (6 + x) / (18 + x) = 1/2.

Solving for x, we get x = 12. Therefore, you need to add 12 more red marbles to the bag to make the probability of drawing a red marble 1/2.

Answer:

y=-70x+350

Step-by-step explanation:

Since x is the number of years since 1995, this means that at 1995, x=0. This also means that in 2000, x=5. The values of the stuffed animals were 350 in 1995 and 0 in 2000. The formula for slope is rise over run, so we can find the answer using this mathematical expression: y2-y1/x2-x1. Plugging in our values, we get 0-350/5-0 which simplifies into -350/5. This further simplifies into -70. Our slope is -70. The definition of y-intercept is the value of y when x=0. We know that x=0 at 1995 and the value for the stuffed animals was 350 at that time. This tells us that the y-intercept is 350. Slope-intercept form is y=mx+b, so plugging in our information, we get y=-70x+350.

The equation representing the data of Romi's stuffed animal inventory is y = -70x + 350

The given problem involves finding an equation in slope-intercept form to represent the data of Romi's stuffed animal inventory from 1995 to 2000. Let's first find the slope and y-intercept of the equation using the given data. We know that the inventory in 1995 was 350 and in 2000 was 0. We can use these two points to find the slope and y-intercept.

Slope (m) = (change in y)/(change in x) = (0 - 350)/(2000 - 1995) = -350/5 = -70

Using the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, we can substitute the values

y = -70x + b

To find the value of b, we can substitute one of the given points into the equation. Let's use the point (0, 350).

350 = -70(0) + b

350 = b

Substituting the value of b back into the equation, we have the final equation:

y = -70x + 350

Answer:

They have 18 vegetable plants.

Step-by-step explanation:

Given:

Emily's family loves to work together  in the garden.

They have a. preference for flowers as 80% of  their plants are flowers and the rest  are vegetables.

They have 90 plants  in the garden.

Now, to find the number of vegetable plants.

Total plants in the garden = 90.

80% of the plants are flowers.

So, number of plants which are flowers = 80% of 90.

[tex]=\frac{80}{100} \times 90[/tex]

[tex]=\frac{7200}{100}[/tex]

[tex]=72\ plants.[/tex]

The number of flower plants = 72.

Total plants = 90 (given)

So, to get the number of vegetable plants we subtract:

[tex]90-72=18\ plants.[/tex]

Thus, vegetable plants = 18.

Therefore, they have 18 vegetable plants.

Given that [tex]\frac{Amount\ of\ abby}{Amount\ of\ Ben} =\frac{2}{7}[/tex]

[tex]Amount\ of\ ben=\frac{7}{2}\times Amount\ of\ abby\\ =\frac{7}{2}\ x[/tex]

Amount of chole + amount of Danesh [tex]=1.5\times[/tex]of abby

                                                                      [tex]=1.5 \ x[/tex]

[tex]x +\frac{7}{2} \ x + 1.5 \ x =360\\\\6x=360\\\\x=\frac{360}{6}\\\\x=60[/tex]

[tex]Amount\ of\ Ben =\frac{7}{2}\ x = \frac{7}{2} \times 60\\\\=7\times 30\\\\=210[/tex]

The amount got by Ben =  £210

£360 is shared between Abby, Ben, Chloe and Denesh.

The ratio of the amount Abby gets to the amount that Ben gets is 2:7.

Chloe and Denesh get 1.5 times the amount Abby gets.

We have to work out the amount of money that Ben gets.

Let the amount  Abby gets = x ...........(1)

According to the given situation

[tex]\rm \dfrac{Amount\; got\; by\; Abby }{Amount \; got \; by \; Ben }= \dfrac{2}{7}[/tex]

[tex]\rm Amount \; got \; by \; Ben = (7/2) x......(2)[/tex]

[tex]\rm Amouut\; goy \; by\; Chole + Amount\; got \; by \; Denesh = 1.5 x........(3)[/tex]

The total amount = £360

From equation (1) (2) and (3) we get

[tex]\rm x + (7/2)x + 1.5x = 360\\x(1+3.5 +1.5) = 360\\x (6) = 360 \\x = 360/6= 60[/tex]

The amount got by Abby = £60

So  the amount got by Ben = 3.5 (60)  =  £210

Answer: 0.236 Liters.

Step-by-step explanation:

First you multiply 1.3 and 0.8 you get 1.064.

You subtract 1.3 and 1.064 and you get your answer 0.236 Liters.

Step-by-step explanation:

There are certain methods for solving a system of equations. Some of which are:

Substitution Method

Substitution method to solve a system of equations is suitable if a variable of a any equation seems isolated or could comfortably be isolated without any ration/fraction resulting.

For example, for the following system of equations

x - 2y = 11....[A]

x = 5 - y....[B]

substituting the value of x = 5 - y from equation [B] into equation [A], so that

(5 - y) - 2y = 11

5 - y - 2y = 11

3y = -6

y = -2

Elimination Method

Elimination method to solve a system of equations is suitable if both equation are in standard form, and just adding or subtracting the equations to determine an equation in one variable.

For example, for the following system of equations

2x + 7y = -5....[C]

5x - 7y = 12....[D]

Adding Equation [C] and Equation [D].

7x + 0 = 7

x = 1

Graphing Method

Sometimes graphing method may be used to solve the system of the equation and visualize the solution.

For example,

y = -2....[E]

y = 3x + 1....[F]

The solution for this system of equation is the point of intersection of both the lines, which is shown in attached figure. The point of intersection is (-1, -2).

Hence, the solution of this system of equations is (-1, -2), as shown in attached figure.
