Step-by-step explanation:

Where

First row is 1

Second row is 3

Third row is 5

This shows that the blocks are set in an oddly fashion

Meaning each row has a odd number of blocks

Therefore from

1 block- row 1

3 blocks- row2

5 blocks- row 3

7 blocks - row 4

9 blocks- row 5

11 blocks - row 6

13 blocks- row 7

15 blocks - row 8

17 blocks- row 9

19 blocks - row 10

Add of the blocks it amounts to 100 blocks

Meaning the triangular will be at the 10th row when she has use 100 blocks

Answer:

I just know that for number 9.)It's C because it has a greater number, meaning it has a greater chance of containing Adam's house number.

the average rate of change of the function over the interval [tex]\(10 < x < 15\)[/tex] is [tex]\( -\frac{6}{5} \)[/tex].

To find the average rate of change of the function over the interval (10 < x < 15), we use the formula:

[tex]\[ \text{Average Rate of Change} = \frac{\text{Change in } f(x)}{\text{Change in } x} \][/tex]

We can calculate the change in [tex]\(f(x)\)[/tex] by subtracting the function values at the end and start of the interval, and the change in x by subtracting the end and start values of x.

Given the function values:

- [tex]\(f(10) = 30\)[/tex]

- [tex]\(f(15) = 24\)[/tex]

And the interval [tex]\(10 < x < 15\)[/tex], the change in [tex]\(f(x)\) is \(f(15) - f(10) = 24 - 30 = -6\)[/tex].

The change in x is [tex]\(15 - 10 = 5\)[/tex].

Now, we plug these values into the formula for the average rate of change:

[tex]\[ \text{Average Rate of Change} = \frac{-6}{5} \][/tex]

So, the average rate of change of the function over the interval [tex]\(10 < x < 15\)[/tex] is [tex]\( -\frac{6}{5} \)[/tex].

The complete Question is given below:

Given the function defined in the table below, find the average rate of change, in simplest form, of the function over the interval 10 < x < 15

Answer:

Unit rate of people per book = 2.5

Step by step explanation:

Given:

Number of peoples =  [tex]10[/tex]

Number of books = [tex]4[/tex]

Their ratios = [tex]10 : 4[/tex]

We have to find the unit rate of people per book.

To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.

Or

For this we will follow the unitary method:

For [tex]4[/tex] book there are [tex]10[/tex] persons.

For [tex]1[/tex] book there will be [tex]\frac{10}{4}[/tex] persons.

So,

The numeric value = [tex]\frac{10}{4}[/tex]

                               = [tex]2.5[/tex]

There are 2.5 people per book and that it also the unit rate of people per book.

Answer: four-fifteenths or [tex]\frac{4}{15}[/tex]

Step-by-step explanation:

What is written with words is mathematically expressed as:

[tex]\frac{9}{15}-\frac{2}{6}[/tex]

We can simplify both fractions, by dividing the numerator and denominator of the first by 3 and dividing the numerator and denominator of the second by 2:

[tex]\frac{9}{15}=\frac{3}{5}[/tex]

[tex]\frac{2}{6}=\frac{1}{3}[/tex]

Then:

[tex]\frac{3}{5}-\frac{1}{3}[/tex]

Calculating the least common multiple (l.c.m) in the denominator as [tex]15[/tex]:

[tex]\frac{9-5}{15}=\frac{4}{15}[/tex] This is the result: four-fifteenths

Step-by-step explanation:

Answer:

Step-by-step explanation:

The absolute change is the difference between the earnings numbers:

  $15,556,113 -8,556,965 = $6,999,148

__

The relative change is the ratio of this difference to the original amount:

  $6,999,148/$8,556,965 × 100% ≈ 81.794748% ≈ 81.79%

The absolute change in opening weekend earnings from the original Footloose to its remake is $6,999,148, and the relative change is approximately 81.74%.

To calculate the absolute change in opening weekend earnings from the original Footloose movie to its 2011 remake, we subtract the earnings of the original movie from the earnings of the remake. Thus, the absolute change is $15,556,113 - $8,556,965 = $6,999,148.

To find the relative change, we divide the absolute change by the original amount and then multiply by 100 to get a percentage. This gives us ($6,999,148 / $8,556,965) * 100 ≈ 81.74%. Hence, the relative change is approximately 81.74%.

The absolute change represents the direct increase in dollar amount, while the relative change gives us the percentage increase from the original to the remake's opening weekend earnings, providing insight into the growth rate.

Answer:64

Step-by-step explanation:

Add 79 with 37 an you will get 116 you need to know the total angle for a triangle is 180 so 180 minus 116 is 64

The measure of the angle y for the triangle is 64°.

The triangle is a shape having three sides and the sum of the angles of the triangle is always equal to 180°.

Here in the given triangle, the two angles are 79° and 37°. The measure of the unknown angle y° will be calculated as:-

y + 79 + 37 = 180

Now solve for the value of angle y below,

y = ( 180 - 79 - 37 )

y = 64°

Therefore, the measure of the angle y for the triangle is 64°.

The system has one solution

Step-by-step explanation:

Let us revise the type of the solutions of a system of equations

The system of equations is:

y = 2x - 12 ⇒ (1)

y = 3x + 12 ⇒ (2)

∵ The equations are in its simplest form

∵ The coefficients of x in the two equations are different

- That is the 1st case above

∴ The system has one solution

Let us prove that by solving the system

To solve the system of equations equate (1) and (2) to find x

∵ 3x + 12 = 2x - 12

- Subtract 2x from both sides

∴ x + 12 = -12

- Subtract -12 from both sides

∴ x = -24

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 3(-24) + 12

∴ y = -72 + 12

∴ y = -60

∴ The solution of the system is (-24 , -60)

The system has one solution

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. Simplify the resulting fraction.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. So, the reciprocal of 7/6 is 6/7. Therefore, 49/50 ÷ 7/6 = 49/50 x 6/7. When we multiply the numerators (49 x 6) and the denominators (50 x 7), we get 294/350. This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 14. Therefore, 294/350 simplifies to 21/25.

Answer:

∠ ABC = ∠ DBE = 65°

∠ ABD = ∠ CBE = 115°

Step-by-step explanation:

See the diagram attached to this question.

Now, ∠ ABC and ∠ DBE are two vertically opposite angles.

So, 3x + 38 = 5x + 20

⇒ 2x = 18

⇒ x = 9

So, ∠ ABC = ∠ DBE = 3(9) + 38 = 65° (Answer)

Again, ∠ ABC and ∠ ABD are supplementary angles.

Then, ∠ ABC + ∠ ABD = 180°

⇒ ∠ ABD = 180° - 65° = 115°

And ∠ ABD = ∠ CBE {Vertically opposite angles}

So, ∠ ABD = ∠ CBE = 115° (Answer)

[tex]y=-2x-8[/tex]

Step-by-step explanation:

Let [tex]y=mx+c[/tex] be the equation of this line.

The points must satisfy this equation.

When x=-8, and y=8, we get:

[tex]8=-8m+c....(1)[/tex]

When x=1, and y=-10, we get:

[tex]-10=m+c...(2)[/tex]

Subtract equation (1) from equation (2) to get:

[tex]m--8m=-10-8[/tex]

9m=-18

m=-2

We put m=-2 in equation to get (2)

-10=-2+c

c=-10+2

Rachel bought six 20-cent stamps and eight 30-cent stamps.

Step-by-step explanation:

Given,

Amount spent on stamps = $3.60 = 3.60*100 = 360 cents

Let,

x = 20 cent stamps

y = 30 cent stamps

According to given statement;

20x+30y=360      Eqn 1

x = y-2                  Eqn 2

Putting value of x from Eqn 2 in Eqn 1

[tex]20(y-2)+30y=360\\20y-40+30y=360\\50y=360+40\\50y=400[/tex]

Final answer:

Rachel bought 8 thirty-cent stamps and 6 twenty-cent stamps. We solved a system of equations representing the cost of the stamps and their quantity relationship to determine the numbers.

Explanation:

Rachel spent $3.60 for stamps to mail packages, buying 30-cent stamps and 20-cent stamps. The number of 20-cent stamps was 2 less than the number of 30-cent stamps. To solve this, we can use a system of equations to represent the total cost and the relationship between the number of stamps:

Let x be the number of 30-cent stamps.

Let y be the number of 20-cent stamps.

Based on the information given:

0.30x + 0.20y = 3.60 (Total cost equation)

y = x - 2 (Relationship between the stamps)

We substitute the second equation into the first equation:

0.30x + 0.20(x - 2) = 3.60

0.30x + 0.20x - 0.40 = 3.60

0.50x = 4.00

x = 8

Now we solve for y using the second equation:

y = 8 - 2

y = 6

So Rachel bought 8 thirty-cent stamps and 6 twenty-cent stamps.

Measures of the angles are 24°, 48° and 108°

Step-by-step explanation:

Let angles be 2x, 4x and 9x.

⇒ 2x + 4x + 9x = 180

⇒ 15x = 180

⇒ x = 180/15 = 12

2x = 24°, 4x = 48° and 9x = 108°
