At the park, there is a triangular sandbox with base = 12ft and height = 4ft. A drawing of the sandbox is shown above. Brie wants to make another, similar sandbox at home with base=8ft.

Given:

Given that the coordinates are (3.9, 5.9), (–1.1, 5.9), (–4.1, 3.9), (–4.1, –2.1)

We need to determine domain and range and also find whether the relation is a function.

Domain:

The domain is the set of all independent x - values.

Thus, we have;

[tex]Domain=\{3.9,-1.1,-4.1\}[/tex]

Thus, the domain is {3.9,-1.1,-4.1}

Range:

The range is the set of all dependent y - values.

Thus, we have;

[tex]Range=\{5.9,3.9,-2.1\}[/tex]

Thus, the range is {5.9,3.9,-2.1}

Function:

We need to determine whether the given relation is a function.

For a relation is said to be a function, if every value of x has only one image in the y - coordinate.

After plotting the graph, it is obvious that the x - value -4.1 has two images 3.9 and 2.1

Hence, the given relation is not a function.

Answer:

a=43

Step-by-step explanation:

w+w+w= 45 which means 15+15+15=45

b+b+b=21 which means 7+7+7=21

s+s+s=12 which means 4+4+4=12

w+b×s= a which means 15+7×4= 43

(hope this helps)

Answer:

The answer to the question is 43

Step-by-step explanation:

Let us recall the values from the following question stated:

Three witches each holds a broom and a spoon, saying plus witch plus witch = 45

Three brooms say broom plus broom plus a broom at = 21

Three spoons say spoon plus spoon plus = 21

Now, let us find when a plain witch plus broom x spoon

Then,

Three witches = 45, resulting to  15+15+15=45

Three brooms (b+b+b) which is =21 or  7+7+7=21

Three spoons (s+s+s) is =12  or 4+4+4=12

we make use of multiplication for the witches, the brooms, and the spoons

Therefore

w+b×s= a,  which is 15+7×4= 43

The correct statements of the triangle are; AC = 5 cm; BA = 4 cm; The perimeter of triangle ABC is 12 cm.

As we know that a, b, and c are midpoints of the sides of right triangle that means midpoint divide the side in equal parts.

Now we have to calculate the sides of triangle ABC by using Pythagoras theorem.

Using Pythagoras theorem in ΔACF :

AC² = FA² + CF²

Thus;

AC² = 3² + 4²

AC = √25

AC = 5

Using Pythagoras theorem in ΔDAB, we have;

BA = √(5² - 3²)

BA = 4 cm

Using Pythagoras Theorem, we have;

CB = √(5² - 4²)

CB = 3 cm

Perimeter of ΔABC = Side AB + Side CB+ Side AC

Perimeter of ΔABC = 4 + 3 + 5

Perimeter of ΔABC = 12 cm

Area of ΔABC = (1/2) * 4 * 3 = 6 cm²

Area of ΔDEF = (1/2) * 8 * 6 = 24 cm²

Area of ΔABC =  (6/24) * Area of ΔDEF

Area of ΔABC = (1/4) * Area of ΔDEF

Given the information provided, we can determine the lengths of the sides of triangle ABC and its perimeter and area.

Given that points A, B, and C are midpoints of the sides of right triangle DEF, we can determine the lengths of the sides using the information provided.

To find the perimeter of triangle ABC, we sum the lengths of all three sides: AB + BC + CA. Substituting the given lengths, AB = BA = 4 cm, BC = 6 cm, and CA = AC = 5 cm, the perimeter is 4 cm + 6 cm + 5 cm = 15 cm.

The area of triangle ABC can be determined using the formula A = bh, where b is the base and h is the height. Triangle ABC and triangle DEF are similar triangles, so their areas are proportional. Since point A is the midpoint of DE, half the base of triangle DEF is equal to the base of triangle ABC. Substituting the given length of DE = 10 cm, the base of triangle ABC is 10 cm / 2 = 5 cm. The height of triangle ABC is equal to the length of AC = 5 cm. Therefore, the area of triangle ABC is A = 5 cm * 5 cm = 25 cm².

Answer:

1.2%

Step-by-step explanation:

Since only 82 were chosen by supreme Court,

The total is 6954

To calculate the percentage of the case decided by the court

82/6954 ×100

8200/6954

1.179~1.2

So the final answer is 1.2%

Final answer:

The percentage of cases decided by the Supreme Court compared to those filed is approximately 1.18%.

Explanation:

To calculate the percentage of cases decided by the Supreme Court out of the total number of cases filed, we use the formula for finding a percentage: (Number of cases decided / Total cases filed) × 100. In this scenario, the Supreme Court decided 82 cases out of 6,954 cases filed.

So, the calculation would look like this:

(82 / 6,954) × 100 = (0.01179) × 100 ≈ 1.18%

Therefore, approximately 1.18% of the cases filed with the Supreme Court were decided by the court.

There are 3 grid nodes suitable for vertex D that lie the same distance from the center of the rectangle as points A and C.

3 rectangles have vertices ABCD that lie on grid nodes.

Answer:

1. Skateboard: 2,743.2. Scooter: 2,590.8. Bike: 4,800. Go-cart: 3,000.

After converting all distances to centimeters, it's clear that Diego's bike traveled the furthest (4800 cm) in 5 seconds, making it the fastest.

Understanding the speed of Diego's vehicles requires us to convert the distances all to the same unit, centimeters. First, we know that 1 foot equals 30.48 cm. Therefore, the skateboard traveled 90 feet * 30.48 cm/foot = 2743.2 cm. The scooter traveled 1020 feet, which means it traveled 1020 feet * 30.48 cm/foot = 31,089.6 cm. The bike traveled 4800 cm, so no conversion is needed for this vehicle. Lastly, 1 kilometer equals 100,000 cm, meaning the go-kart traveled 0.03 kilometers * 100,000 cm/kilometer = 3,000 cm. Now that we have all the distances in the same unit, we can compare and state that the bike traveled the furthest in 5 seconds, making it the fastest.

Step-by-step explanation:

Answer:

36,000 people are likely to vote in favour of the new shopping centre

Step-by-step explanation:

Given

Population = 50,000

Total Sample = 25

18 favoured opening a new shopping centre

Required

Likely number of people to vote in favor of the new shopping center.

First, we need to represent the sample in proportion.

Let p represent the proportion

Since 18 out of 25 are in support of opening a new center,

p = 18/25

Having solved for the proportion,the next step is to calculate the expected number of people.

This is calculated by multiplying p by the total population.

Given that population = 50,000

The expected outcome = 18/25 * 50,000

Expected outcome = 18 * 2,000

Expected outcome = 36,000

Hence, 36,000 people are likely to vote in favour of the new shopping centre

Answer:

36,000 voters

Step-by-step explanation:

Here we have a question on proportion

Proportion of voters that favored creating a new shopping center = 18/25

That is the point estimate of voters that favored creating a new shopping center = 18/25

Therefore, among 50,000 voters in Harrisburg the number of voters that are likely to vote in favor of the new shopping center, based on the point estimate of the sample is given by the following expression;

18/25 × 50,000 = 36,000 voters.

Answer:

a. 0.69x + 0.14

b. 5.67 - 30.48a

c. 1.1x - 3.01y

Step-by-step explanation:

a) 2.56x + 0.14 − 1.87x

To simplify this algebraic expression, you start by collecting like terms;

2.56x − 1.87x  + 0.14

Then perform arithmetic operation

0.69x + 0.14

b) 7.32a + 2.1 (2.7 − 18a)

Here; first, the bracket must be opened

To open the bracket; each expression in the bracket is multiplied by 2.1. This leaves us with

7.32a + 2.1 * 2.7 − 2.1 * 18a

7.32a + 5.67 - 37.8a

Then, you collect like terms

7.32a - 37.8a + 5.67

Then perform arithmetic operation

-30.48a + 5.67

Rearrange

5.67 - 30.48a

c) 0.12x + 0.34y + 0.98x − 3.35y

Here, you start by collecting like terms

0.12x + 0.98x + 0.34y − 3.35y

Then perform arithmetic operation

1.1x - 3.01y

Part 1:-

- The measure of arc [tex]\( BD \)[/tex] is 260°.

- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).

- The measure of arc [tex]\( ABC \)[/tex] is 80°.

To find the measure of each arc in the circle, we need to remember that the total degrees in any circle is 360°. The diagram shows a circle with specific arcs and angles labeled.

Here are the steps to find each arc's measure:

1. Measure of arc [tex]\( BD \)[/tex]:

  - Arc [tex]\( BD \)[/tex] is opposite the central angle [tex]\( \angle BRD \)[/tex], which is not directly given.

  - Since [tex]\( \angle BRC \)[/tex] is 40° and [tex]\( \angle CRD \)[/tex] is 60°, then [tex]\( \angle BRD = 360° - (\angle BRC + \angle CRD) \)[/tex].

  - Calculating [tex]\( \angle BRD \)[/tex] gives [tex]\( 360° - (40° + 60°) = 260° \)[/tex].

  - Therefore, the measure of arc \( BD \) is 260°.

2. Measure of arc [tex]\( ADB \)[/tex]:

  - Arc [tex]\( ADB \)[/tex] includes arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex].

  - We already know [tex]\( DB \)[/tex] is 260°.

  - [tex]\( AD \)[/tex] is opposite the central angle [tex]\( \angle ARD \)[/tex], which is given as 120°.

  - Adding them together, the measure of arc [tex]\( ADB = \angle ARD + \angle BRD = 120° + 260° = 380° \).[/tex]

  - This exceeds 360°, which suggests an error. Since [tex]\( AD \)[/tex] and [tex]\( BD \)[/tex] are parts of the circle that add up to its whole circumference, they should add up to 360°, not more. Hence, [tex]\( ADB \)[/tex] should be [tex]\( 360° - \angle BCD \)[/tex] which is 360° - 40° = 320°.

3. Measure of arc [tex]\( ABC \)[/tex]:

  - Arc [tex]\( ABC \)[/tex] includes arcs [tex]\( AB \)[/tex] and [tex]\( BC \).[/tex]

  - [tex]\( BC \)[/tex] is opposite the central angle [tex]\( \angle BRC \)[/tex], which is given as 40°.

  - [tex]\( AB \)[/tex] is the rest of the circle not included in \( ADB \), so [tex]\( AB = 360° - \angle ADB \)[/tex].

  - Since we've found an inconsistency with [tex]\( ADB \)[/tex], we should instead calculate [tex]\( AB \)[/tex] as [tex]\( 360° - (BD + CD) = 360° - (260° + 60°) = 40° \).[/tex]

  - Adding \( AB \) and \( BC \), the measure of arc [tex]\( ABC = AB + BC = 40° + 40° = 80° \).[/tex]

There seems to be an error with the measure of arc [tex]\( ADB \)[/tex] as calculated before. Arcs [tex]\( AD \)[/tex] and [tex]\( DB \)[/tex] should add up to 360° because they complete the circle together. It's also worth noting that in a properly drawn circle, the sum of the measures of arcs [tex]\( BC \)[/tex], [tex]\( CD \)[/tex], and [tex]\( DA \)[/tex]should add up to 360°. If [tex]\( BC \)[/tex] is 40° and [tex]\( CD \)[/tex] is 60°, then [tex]\( DA \)[/tex] should be 360° - (40° + 60°) = 260°, not 120°. This discrepancy suggests there may be a mistake in the given information or a misinterpretation of the diagram.

To summarize, given the information provided:

- The measure of arc [tex]\( BD \)[/tex] is 260°.

- The measure of arc [tex]\( ADB \)[/tex] should be 320° (corrected).

- The measure of arc [tex]\( ABC \)[/tex] is 80°.

Answer:

jl = 19cos24 = 17.4.   jk = 19sin24 = 7.7.

Step-by-step explanation:

We have a rt. triangle; the hyp is kl

and the hor side is jl. The angle between the hor side and hyp = 24 deg.

The value of JL rounding up to the nearest tenth will be 17.36.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Angle is the measurement of rotation motion for example if you want to measure the length in rotation geometry then it is helpful.

Given that the KL = 19 units, the angle LJK = 24°

Now by a trigonometric function

cos24° = Jl/19

JL = 19 × cos24°

JL = 17.36 hence, the correct answer or the length of the JL is 17.36 units.

Janeel wants the area of the image to be one eight of the original photograph. Write an equation to represent the area of the reduced image. Find the dimensions of the reduced image.

Correct Answer:

A) [tex](10-x)(12-x)=15[/tex]

B) Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

Step-by-step explanation:

a. Write an equation to represent the area of the reduced image.

Let the reduced dimensions is by x , So the new dimensions are

[tex]length=10-x\\breadth=12-x[/tex]

According to question , Area of new image is :

⇒ [tex]Area = \frac{1}{8}Length(breadth)[/tex]

⇒ [tex]Area = \frac{1}{8}(10)(12)[/tex]

⇒ [tex]Area = 15[/tex]

So the equation will be :

⇒ [tex](10-x)(12-x)=15[/tex]

b. Find the dimensions of the reduced image

Let's solve :  [tex](10-x)(12-x)=15[/tex]

⇒ [tex]120-10x-12x+x^2=15[/tex]

⇒ [tex]120-22x+x^2=15[/tex]

⇒ [tex]x^2-22x+105=0[/tex]

By Quadratic formula :

⇒ [tex]x = \frac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

⇒ [tex]x = \frac{22 \pm8 }{2}[/tex]

⇒ [tex]x = \frac{22 +8 }{2} , x = \frac{22 -8 }{2}[/tex]

⇒ [tex]x = 15 , x =7[/tex]

x = 15 is rejected ! as 15 > 10 ! Side can't be negative

⇒ [tex]x =7[/tex]

Therefore, Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch
