There are 18 apples in each basket from the given situation.

Given that, Danielle picks 744 apples at an apple orchard. She divides the apples equally into 40 baskets.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Part A:

744 ÷ 40

40 | 744 | 18

      40

   _____

      344
      320
   _____

       24

The first digit of quotient 18 is in tens place.

Part B:

There are 18 apples in each basket.

Part C:

There are 24 apples will be left.

Therefore, there are 18 apples in each basket from the given situation.

Answer:

Step-by-step explanation:

3x+4=9x+3, we will add and subtract the variable and the numbers so we have, x in one side and the numbers on the other side

4-3=9x-3x

1=6x

x=1/6

Answer:

x = 1/6

Step-by-step explanation:

1. Add and subtract the variable and the numbers.

So far: 4 - 3 = 9x - 3x

4 - 3 = 9x - 3x

2.  Simplify.

4 - 3 = 1.

9x - 3x = 6x.

To do addition with variables, delete the variables, which now is 9 - 3, easy, 6, add the x back (only to the answer), so 6x.

Since 1 is on 1 part of the equal side, because 4 - 3 = 1.

And is 1 = 6x.

1/6 then is your final answer.

Answer:

The solution to the system of equation is (1,-4)

Step-by-step explanation:

Here, we want to find the solution to the system of equations

Since we have y in both places, we can equate the two

That would be;

-x-3 = -7x + 3

-x + 7x = 3 + 3

6x = 6

x = 6/6

x = 1

y = -x - 3

y = -1 -3

y = -4

So the solution to the system of equations is (1,-4)

Answer:

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

Step-by-step explanation:

Given

Given that 74% of the animals at an animal shelter are dogs.

To determine:

About what fraction of the animals at the shelter are dogs?  

Using the equation to find a fraction equivalent to 74%

 [tex]\:74\%=\:\frac{74}{100}[/tex]

Divide numerator and denominator by 2

         [tex]=\frac{\frac{74}{2}}{\frac{100}{2}}\:\:[/tex]

Cancel the common factor 2.

        [tex]=\frac{37}{50}[/tex]

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

Answer:

-154

Step-by-step explanation:

The formula for the sequence is: an = -11n + 22

If n equals 1 you get the first term, and so on.

For the 16th term n=16.

-11(16) + 22

-176 + 22

-154

Answer:

3n - 2 = 13

Step-by-step explanation:

A number tripled would represent a number times 3, so it would be "3n"

If it is increased by -2, then you would be adding -2, or subtracting by 2

lastly, you put " = 13" because "is" in an equation also means "equals"

orthocenter

Step-by-step explanation:

I just did it

The term which describes the point V is Orthocenter, the correct option is B.

The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).

If the triangle has its vertices as  [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex], then the coordinates of the centroid of that triangle is given by:

[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]

We are given that;

The figure

Now,

We know that in a triangle, whenever a line that passes through a vertex of the triangle such that is perpendicular to the opposite side is called an altitude of the triangle;

So, the point where all the three altitudes of the triangle meets is called its orthocenter .

From the given figure , we can conclude that the point V is the intersecting points of all the altitudes of the triangle STU.

Therefore, by centroid concept the answer will be Orthocenter.

Answer:

y=2x-7

Step-by-step explanation:

The easiest way to answer this would be by using the slope-intercept form equation, y=mx+b. In this case, we can use our given in information to plug in values and find the equation.

Firstly, let's assess what know and what we don't:

Given the point (2,-3), we know that x=2 and y=-3. Now the slope for a perpendicular line can be found using a negative reciprocal, since the product of the slopes of both lines should equal -1. Therefore the slope must be 2.

All that's left is b, the y-intercept. To solve for this, we simply plug in what we have.

y=mx+b

-3=2(2)+b

-3=4+b

-3-4=b

-7=b

Now that we have b, we can write the equation:

y=2x-7

Question:

Which set of ordered pairs (x,y) could represent a linear function?

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

[tex]\mathbf{B}= \,\,\left\{(-1, -8),\,\,(0, -3),\,\,(1, 3),\,\,(2, 8)\right\}[/tex]

[tex]\mathbf{C}= \,\,\left\{(-9, 5),\,\,(-3, 3),\,\,(3, 0),\,\,(9, -2)\right\}[/tex]

[tex]\mathbf{D}= \,\,\left\{(1, -8),\,\,(2, -6),\,\,(3, -3),\,\,(4, 0)\right\}[/tex]

Answer:

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

Step-by-step explanation:

Given

Ordered pairs A - D

Required

Which represents a linear function?

To do this, we simply calculate the slope (m) of each ordered pairs.

[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]

Considering A:

[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (4,5)[/tex]

[tex]m = \frac{5 - 9}{4 -2} = \frac{-4}{2} = -2[/tex]

Consider the another pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (6,1)[/tex]

[tex]m = \frac{1 - 9}{6 -2} = \frac{-8}{4} = -2[/tex]

Consider the another pairs

[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (7,-1)[/tex]

[tex]m = \frac{-1 - 9}{7 -2} = \frac{-10}{5} = -2[/tex]

The slope is uniform all through.

i.e.

[tex]m = -2[/tex]

Hence, this can be a linear function

Considering B:

[tex]\mathbf{B}= \,\,\left\{(-1, -8),\,\,(0, -3),\,\,(1, 3),\,\,(2, 8)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (0,-3)[/tex]

[tex]m = \frac{-3 - (-8)}{0 - (-1)} = \frac{-3 +8}{0 +1} = \frac{5}{1} = 5[/tex]

Consider the another pairs

[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (1,3)[/tex]

[tex]m = \frac{3 - (-8)}{1 - (-1)} = \frac{3 +8}{1 +1} = \frac{11}{2} = 5.5[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = 5[/tex] and [tex]m = 5.5[/tex]

Hence, this can't be a linear function

Considering C:

[tex]\mathbf{C}= \,\,\left\{(-9, 5),\,\,(-3, 3),\,\,(3, 0),\,\,(9, -2)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (-3,3)[/tex]

[tex]m=\frac{3-5}{-3-(-9)} = \frac{3-5}{-3+9} = \frac{-2}{6} = -\frac{1}{3}[/tex]

Consider the another pairs

[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (3,0)[/tex]

[tex]m=\frac{0-5}{3-(-9)} = \frac{0-5}{3+9} = \frac{-5}{12} = -\frac{5}{12}[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = -\frac{5}{12}[/tex] and [tex]m = -\frac{1}{3}[/tex]

Hence, this can't be a linear function

Considering D:

[tex]\mathbf{D}= \,\,\left\{(1, -8),\,\,(2, -6),\,\,(3, -3),\,\,(4, 0)\right\}[/tex]

Consider the following pairs

[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (2,-6)[/tex]

[tex]m = \frac{-6 - (-8)}{2 - 1} = \frac{6 + 8}{1} = \frac{14}{1} = 14[/tex]

Consider the another pairs

[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (3,-3)[/tex]

[tex]m = \frac{3 - (-8)}{-3 - 1} = \frac{3 + 8}{-4} = \frac{11}{-4} = -\frac{11}{4}[/tex]

The calculated slopes are not equal.

i.e.

[tex]m = -\frac{11}{4}[/tex] and [tex]m = 14[/tex]

Hence, this can't be a linear function

From the calculations above:

Only (A) can be a linear function
