Answer:

Slope=4.25

Step-by-step explanation:

Formula for slope is y2-y1/x2-x1

Y1=51,y2=17,x1=12,x2=4

Input this values into the above formula

17-51/4-12

Slope=-34/-8

Divide both numerator and denominator by -2

Slope=17/4

Slope=4.25

Surveys enable the collection of specific data points from a diverse population, allowing for a more accurate estimation of the percentage of citizens with children in school readiness support. This method ensures inclusivity and reliability in gathering information for decision-making purposes.

Conducting a survey would be the best method to gather information on the percentage of citizens in Los Angeles County who have children in school readiness support. Surveys allow for direct feedback from a representative sample of the population, providing a comprehensive understanding of the situation.

In the survey, a representative sample of citizens across different demographics can be asked whether they have children enrolled in school readiness support programs. By analyzing the responses, Los Angeles County can estimate the percentage of citizens with children in such programs.

Answer:

option 1

Step-by-step explanation:

The shaded area is area of circle - area of 2 congruent triangles

area of circle = πr²

Note that the base and height of both triangles is the radius

Area o triangle = [tex]\frac{1}{2}[/tex] ×  r × r = [tex]\frac{1}{2}[/tex]r²

area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × r² = r²

area of shaded region = πr² - r² = r²(π - 1) → (1)

To represent the area of the shaded region in the figure, use the expression "r² (π+1)" as it closely approximates the calculation for the shaded area.

In the figure described, ABO and GOF are right triangles, and there's a shaded region within these triangles. To represent the area of the shaded region, we can consider the difference between the areas of the larger triangles ABO and GOF and the smaller semicircles centered at O within each triangle.

The area of a triangle is given by (1/2) × base × height, and the area of a circle is πr², where "r" is the radius.

Calculate the area of ABO: (1/2) × AB × AO

Calculate the area of GOF: (1/2) × GO × GF

Calculate the area of one semicircle: (1/2) × πr²

Now, to find the area of the shaded region, subtract the sum of the areas of the two semicircles from the sum of the areas of the two triangles:

Shaded Area = (ABO - πr²) + (GOF - πr²)

So, the representation for the area of the shaded region is:

Shaded Area = (1/2) × AB × AO + (1/2) × GO × GF - πr²

Therefore, option 2, "r² (π+1)," is the closest representation of the area of the shaded region.

Answer:

3,854

Step-by-step explanation:

There’s 82 kids each learned 47 lines you would multiply

The children learned a total of 3854 lines of the song. This is found by multiplying the number of children by the number of lines in the song.

This problem involves simple multiplication. Since each child needs to learn one line of the song, and the fun song has 47 lines, to find the total number of lines the children learned altogether, you simply multiply the number of children by the number of lines in the song. Therefore, 82 (number of children) x 47 (number of lines in the song) equals 3854. So, the children learned 3854 lines in total.

Step-by-step explanation:

For the given set of equations, x = 0 and y = 3.

Step-by-step explanation:

Step 1:

From the question,

[tex]-x + 2y = 6[/tex], take this as equation 1,

[tex]6y =x+18, x - 6y = -18[/tex], take this as equation 2.

Step 2:

When we add equation 1 and equation 2, the x variable is canceled out and y can be calculated.

[tex]-4y = -12, y = \frac{-12}{-4}, y = 3.[/tex]

Step 3:

Substituting this value of y in any of the previous equations we will get x's value.

Here this value of y i.e y = 3 is substituted in equation 1.

[tex]-x + 6 = 6, -x = 6 -6, -x=0, x=0.[/tex]

So we have x = 0 and y = 3.

The question means in Portuguese: In a certain addition of three consecutive natural numbers, the smallest is 49. What should the sum be?

English: Since 49 is the smallest number, the next number up and the next number up give us the 3 consecutive numbers. So 49+50+51 is 150.

Portuguese: Como 49 é o menor número, o próximo número acima e o próximo número acima nos dão os 3 números consecutivos. Então 49 + 50 + 51 é 150.

Answer: 1) 1 1/2, 2 1/4, and 4

Step-by-step explanation: 1) We know that the equation would be the cups of flour being multiplied by the batches. Like, 5 times 3/4 would equal 15/4 which would simplify to 3 3/4.

                 So, to find the first missing number, we do 2 x 3/4, which equals 6/4( 1 1/2).

                The next missing number would be 3, because we're going in order-- like 1, 2, 3, 4. So we do 3 x 3/4.

               We then don't have a number for batches this time. So we still do, 3/4 x 3 but this time we cross out both the 3 on the top and we're left with 4, our answer.

Answer:

1716 m^3

Step-by-step explanation:

We can find the volume of a triangular prism by thinking about it like this - it's half of a rectangular prism. It's just be cut diagonally. So we can imagine that the measurements of the potential rectangular prism are 6m x 26 m x 22m.

Volume of rectangular prism:

6*26*22 = 3432

Volume of triangular prism:

1/2 of rectangular prism - 3432/2 = 1216

Answer:

Step-by-step explanation:

Volume of the prism is calculated by base and height

V= bh

From the figure, base = 6m

Where height = 26m

V = 26m x 6m

= 156m^2

We have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2

Solution:

Given that,

For a game, Tony has a rectangle drawn on a piece of paper that has an area of 18 in.^2

In order to have a similar rectangle that's area is only 2 in.^2

Thus, we need to find the scale factor

Let "c" be the scale factor

Let "x" be the area of original rectangle

Let "y" be the area of dilated rectangle

Therefore,

[tex]c = \frac{y}{x}\\\\c = \frac{2}{18}\\\\c = \frac{1}{9}[/tex]

Therefore, we have to divide the dimensions by 9 to get a similar rectangle that's area is only 2 in.^2

Answer:

Divide them by three.

Maria had 2 yards of trim when she started.

Step-by-step explanation:

Step 1:

All of the sides of the triangle is 22 inches long each.

The total length of the sides of the triangle [tex]= 3(22) = 66.[/tex]

So the total length of the trim for the banner is 66 inches long.

If Maria still has [tex]\frac{1}{2}[/tex] a foot of trim left, she had 6 inches of the trim left.

The length of the trim when she started[tex]=66 +6 = 72[/tex] inches.

Step 2:

Now we need to convert the 72 inches into yards.

We have 1 inch = 0.0277778 yards.

So 72 inches [tex]= 0.0277778(72) = 2.[/tex]

So Maria had 2 yards of trim when she started.

The surface area of the rectangular pyramid is,

⇒ 507 units²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The rectangular pyramid is shown in image.

Step-by-step explanation:

4) 416 = 2x² - 6x

2x² - 6x - 416 = 0

x² - 3x - 208 = 0

x² - 16x + 13x - 208 = 0

x(x - 16) + 13(x - 16) = 0

(x - 16)(x + 13) = 0

x = 16, -13(not possible)

So 16 rows

5) y = a(x - h)² + k

y = a(x - 3)² - 7

When x = 1, y = -10

-10 = 4a - 7

4a = -3

a = -¾

y = -¾(x - 3)² - 7
