Yolanda and her 3 brothers are sharing 156 toy dinosaurs. By dividing 156 by the total number of children, which is 4, we find that each child gets 39 toy dinosaurs.

The question requires us to divide a certain number of items, specifically toy dinosaurs, equally among a group of children. Yolanda and her 3 brothers share a total of 156 toy dinosaurs. To find out how many dinosaurs each child gets, we need to perform a simple division operation.

Since there are 4 children in total (Yolanda plus her 3 brothers), we divide the total number of toy dinosaurs by 4:

Therefore, each child would receive approximately 39 toy dinosaurs.

Final answer:

To determine how many toy dinosaurs each child receives, divide 156 (the total number of dinosaurs) by 4 (the number of children), resulting in 39 dinosaurs per child.

Explanation:

The subject of this question is Mathematics, and it belongs to the Middle School grade level. The question involves dividing a set of items equally among a group of children, which is a basic arithmetic problem.

Yolanda and her 3 brothers together make a group of 4 children. To find out how many toy dinosaurs each child gets, we divide the total number of toy dinosaurs by the number of children:

Total number of toy dinosaurs: 156
Number of children: 4

Number of dinosaurs per child = 156 ÷ 4
= 39

So, each child would receive approximately 39 toy dinosaurs.

Answer:

5.62 = (5 x 1) + (6/10) + (2/100)

Step-by-step explanation:

5.62 = (5 x 1) + (6/10) + (2/100)

The number of nights studies in a month is 20.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Number of nights in a month = 30

The number of nights studied in a month.

= 2/3 x 20

= 2 x 10

= 20

Thus,

The number of nights is 20.

Answer:

x = 8.64

Step-by-step explanation:

12% of 72 = (12/100) * 72/x

= 0.12 * 72

x = 8.64

8.64 is 12% of 72. Determining any kind of percentage will not be a challenge for anybody if the above procedure is followed step by step.

There are 9 tiles are along an edge of the room.

Here,

A square room has a tiled floor with 81 square tiles.

What is Area of a square?

In square all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side.

Now,

A square room has a tiled floor with 81 square tiles.

Number of tiles on edge of the room is equal to length of one side of the room.

Hence, we have to find the length of each side of a square room.

For this,

Area of square room = [tex]side^{2}[/tex] = [tex]81[/tex]

⇒ side = √81 = 9

So, There are 9 tiles are along an edge of the room.

The average rate of change of the function f(x)=x^2-x-1 over the interval from -1 to 1 is calculated as the change in the function's values over the change in x, which results in -1.

The average rate of change of a function f(x) over a given interval [a, b] is defined as the change in f(x) divided by the change in x. It is equal to the value of the function at point b minus the value of the function at point a, divided by (b-a).

For the function f(x)=x^2-x-1, we are given the interval from -1 to 1. In this case, a=-1 and b=1.

So first calculate f(a) and f(b), i.e., f(-1) = (-1)^2 -(-1)-1 = 1, and f(1) = (1)^2 -(1)-1 = -1.

Then, plug these values into the average rate of change formula, which gives us (-1-1) / (1 - (-1)) = -2 / 2 = -1. So the average rate of change of the function f over the interval from -1 to 1 is -1.

Final answer:

To model 5 x 2/3, think of having 5 groups of 2/3 each. Multiplying 2/3 by a fraction less than one yields a smaller product. Victor will eat 5/36 of the whole apple pie, and an angle of 100 degrees represents 100/360 of a full circle.

Explanation:

To model 5 x 2/3, you can visualize having 5 groups of something, with each group containing 2/3 of that item. For example, if you have 5 pies, and you take 2/3 out of each pie, you would have a total of (5 x 2/3 = 10/3) pies.

When you multiply 2/3 by a fraction less than one, the product is smaller than the original fraction of 2/3 because you're effectively taking a portion of a portion, which reduces the overall size.

For the apple pie scenario, Victor plans to eat 1/6 of the 5/6 of a pie that is left, so the amount he will eat is (5/6 x 1/6 = 5/36) of the whole pie, which means the correct answer is Option B, 5/36.

Without the visual model provided, it is challenging to determine exactly which expressions Matt could have been working out. However, if you can provide the model, the answer would depend on the relationship between the hearts, squares, and the blank squares in Matt's model.

An angle of 100 degrees represents 100/360 or roughly 5/18 of a full circle since a full circle has 360 degrees. Therefore, the answer is Option C, 100/360.

Answer:

C. [tex]y-4=-\frac{9}{11}(x+8)[/tex]

Step-by-step explanation:

The point slope form is  [tex]y-y_1=m(x-x_1)[/tex] where m is the slope,

First we are going to calculate [tex]m[/tex]:

If you have two points:

[tex]A=(x_1,y_1)\\B=(x_2,y_2)[/tex]

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

In this case: A=(-8,4) and B=(3,-5)

[tex]x_1=-8, y_1=4\\x_2=3, y_2=-5[/tex]

Replacing in the formula:

[tex]m=\frac{-5-4}{3-(-8)}=-\frac{9}{11}[/tex]

Then [tex]y-y_1=-\frac{9}{11}(x-x_1)[/tex],

Now we have to replace with: [tex]x_1=-8, y_1=4[/tex],

[tex]y-y_1=-\frac{9}{11}(x-x_1)\\\\y-4=-\frac{9}{11}(x-(-8))\\\\y-4=-\frac{9}{11}(x+8)[/tex]

Then the equation in point-slope form of a line that passes through the points (3, −5) and (−8, 4) is:

C. [tex]y-4=-\frac{9}{11}(x+8)[/tex]
