Answer:

0.9 Litres or 900 ml

Step-by-step explanation:

First we will find out the total volume of Sunflower oil he has.

Sunflower Oil bought = 6 cana x 3 litre = 18 litres

Now we divide this 18 litres into 20 parts to find out the volume of sunflower oil per bottle:

[tex] \frac{18}{20} \\ = \frac{9}{10} \\ = 0.9litres \: or \: 900ml[/tex]

Answer:

y [tex]\geq[/tex] 4x - 6

Step-by-step explanation:

1. Find the slope using the slope formula (rise over run)

2. Use the slope and one of the points to solve for the y-intercept (b)

3. Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line

Answer:

x=

Step-by-step explanation:

Given the midpoint formula: ([tex]\frac{x_2+x_1}{2},\frac{y_2+y_1}{2}[/tex]),the Segment Addition Postulate, and the line attached, find x, HK, HJ, KJ

1st step is in the picture.

doing the first step gives us [tex]x + 9[/tex]

Since k is the midpoint, both sides of the midpoint are the same length

so we can use the equation [tex]3x - 10 = x+9[/tex]

subtract x from both sides: [tex]3x-10-x=x+9-x[/tex]

[tex]2x-10=9[/tex]

[tex]2x-10+10=9+10[/tex]

[tex]2x=19[/tex]

[tex]2x/2=19/2[/tex]

[tex]x=9.5[/tex]

Now that we know x, we can substitute to find HK, HJ, and KJ

[tex]HK = 3(9.5)-10[/tex]

[tex]HJ = 4(9.5)+19[/tex]

[tex]KJ = x +9[/tex]

[tex]HK = 28.5 -10\\HJ = 38+19\\\\KJ = 9.5 + 9\\HK = 18.5\\HJ=57\\KJ = 18.5\\[/tex]

Our HK and KJ answer is correct because they are the same, and the midpoint of HK and KJ is point K.

Step-by-step explanation:

If a naval submarine was operating 310 feet below the surface of the ocean. To pass above an underwater mountain, or seamount, it rose 165 feet then 145 is the position of the submarine relative to the surface of the ocean now.

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

If a naval submarine was operating 310 feet below the surface of the ocean. To pass above an underwater mountain, or seamount, it rose 165 feet. we need to find the position of the submarine relative to the surface of the ocean now.

The submarine initial position= 310 feet.

To pass above an underwater mountain, or seamount, it rose = 165 feet.

The position of submarine is

310-165

=145 feet.

Therefore  the position of the submarine relative to the surface of the ocean now is 145 feet.

The linear cost function is C(x) = 15x + 3250 and the cost function in marginal cost: $15; 150 items cost $5500 to produce is $ 5500 .

Let C(x) is that the total value, and x is that the range of things.

The slope "m" is named the cost and "b" is named the charge.

The value of m is $15 and the price of "x" is 150.

Total cost of 150 items are $5500

Substitute all the values within the equation (1) , we get

   5500 = 15 (150) + b

    5500 = 2250 + b

    3250 = b

Hence , linear cost function is given by C(x) = 15x + 3250

The length of one of the sides of the sandbox is 9.43 feet.

A square is defined as a polygon that has four sides and is a closed, two-dimensional (2D) object. A square has equal and parallel sides on all four sides.

The area of a square is equal to the squared of sides or the multiplication of two sides.

Here the square sandbox has an area of 89 ft²

So the area would be as

⇒ the length of side = √area of the sandbox

⇒ the length of side = √89

⇒ the length of side = 9.43

Therefore, the length of one of the sides of the sandbox is 9.43 feet.

The bookstore pays the publisher $27 for each book thus making a profit of 30%.

The profit is defined as the difference between the sell price and the cost price.

The sell price is defined as the price at which an object is sold.

The cost price is defined as the price at which an object is bought.

When the sell price is greater than the cost price profit is made by the seller.

Let the cost price (price paid to publisher) be x dollars.

Therefore when sold at a profit of 30% then

profit= 30%of x=0.3x dollars

Now the sell price = cost price +profit

∴Sell price= x+0.3x=1.3x

But the sell price is given as $35.10

So we can equate the two terms to get a linear equation in x.

∴1.3x=35.10

or, x=35.10÷1.3

or, x=27

Therefore the cost price is $27.

Answer:

the smallest even whole number which is divided by 3 is 6

Answer:

10/9

Step-by-step explanation:

Answer:

y = 9x + 7

Step-by-step explanation:

Line is parallel to y = 9x + 4 and passes through the point (-1, -2)

m = slope

the slope of the line is the same for both lines, m = 9

the equation of the parallel line is y = 9x + a

-2 = (9) * (-1) + a

a = 7

y = 9x + 7

According to the information, it can be inferred that in the room worth 3,000, the break-even point would be 25 students enrolled. On the other hand, in the room of 200, the break-even point would be 7 students enrolled.

The break-even point is an economic term to refer to the moment when a company's income covers its fixed and variable expenses, that is, when you manage to sell the same amount you spend, you neither win nor lose, you have reached the break-even point.

Thus, calculating the break-even point is essential for companies to assess their profitability, since in this way it is possible to know how much they need to sell to generate profit. Knowing this value, even before starting a new project, allows you to know how financially interesting your business idea is.

To calculate the break-even point, we must take into account the expenses that the students will have to offer their service:

According to the above, the expenses in case A, with room 1 would be:

On the other hand, the expenses in case B with room 2 would be:

So, we know that in case A the expenses are going to be 3,750 and in case B the expenses are going to be 950. To find the break-even point for each case, we must divide this value by the price at which they are going to sell the item. course to students. However, it should be clarified that it must be divided by 150 because 50 will be used to pay for each student's handouts.

3,750 ÷ 150 = 25

950 ÷ 150 = 6.33 = 7

According to the above, the break-even point for case A would be 25 students. Additionally, in case B the balance point would be 6.33 students who are close to 7.

To conclude, it can be stated that the best option would be to take room 2 because they will have fewer expenses and will have to sell fewer units of their course to reach the break-even point.

By taking the quotient between the two volumes in ounces, we conclude that you will need about 8 cans to fill the bottle. So the correct option is C.

We know that the 2-liter bottle holds (67 + 3/5) ounces of water, and each one of the cans holds a volume of 8 ounces.

To see how many cans we need to fill the bottle, we need to take the quotient between the two volumes (using ounces in both cases, obviously), we will get:

Q = (67 + 3/5)/8 = 8.45

So you need 8.45 cans to completely fill the 2 liter bottle, then we can see that the correct option will be C, 8 cans, as that is the best estimation.
