Answer:

3.32ft

Step-by-step explanation:

The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.

Using Pythagoras Theorem:

Hypotenuse²=Adjacent²+Opposite²

6²=5²+x²

x²=36-25

x²=11

x=√11=3.32 ft.

The wires are attached 3.32 ft from the base of the pole on the ground

Answer:

The question can be answered by using a Pythagoras' Theorem :  [tex]c^2=a^2+b^2[/tex] to find the base of  the pole to which each wire is  attached to the ground.

Step-by-step explanation:

the base of the pole is represented by b.

the height of the pole is represented by a= 5 feet

the length of t he wire is represented by c=5 feet.

Thus, using the Phytagoras Theorem,

c^2=a^2+b^2,

[tex]6^2=5^2+b^2\\36=25+b^2,\\36-25=b^2\\Thus, b^2=11,\\b=\sqrt 11[/tex] or b=3.3.

Thus , each wire i attached by about 3.3 feet to the base of the pole.

Answer:

D

Step-by-step explanation:

The area of the segment is 81/4π square units.

To find the area of the segment, we need to use the formula for the area of a segment of a circle.

The area of a segment is given by the formula:

A = (θ/360) * π * r^2

where θ is the central angle in degrees, π is approximately 3.14159, and r is the radius of the circle.

Given that the central angle θ is 90° and the radius r is 9, we can plug these values into the formula:

A = (90/360) * π * 9^2

A = (1/4) * π * 81

A = (1/4) * 81π

A = 81/4 * π

So, the area of the segment is 81/4π square units.

Answer:

32.692307692308%

Step-by-step explanation:

Let's go over the facts we know:

- There are 13 hearts in a deck of cards, 2 through ace

- There are 4 "2's" in a deck of cards, one for each suit

- There are 52 cards in a standard deck

The first step is to find the ratio.

Add the 13 hearts to the 4 "2's" to get the amount of cards to be drawn.

13 + 4 = 17.

Based on this, we know the ratio of hearts and "2's" to total cards is 17:52.

In other words, there is a 17 out of 52 chance that the card drawn will be a heart or a 2.

Now, we need to convert it to a percentage. To do so, divide 100 by 52. We get 1.92307692308. Now, multiply both 52 and 17 by 1.92307692308, and put the product with 17 as the numerator of the fraction and the product with 52 as the denominator. We get 32.692307692308/100. As a percent, this is written as 32.692307692308%

Therefore, the final answer is 32.692307692308%.

The length of the ladder is 5 feet

Step-by-step explanation:

Please kindly check the attached file for explanaion

The ladder is 5 feet long.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles

Given,

Let x = height ladder reaches on wall

Let x+1 = length of the ladder

the three pieces of this form a right triangle

so (x+1)² = x² + 3²

x² +2x + 1 = x² +9

2x = 8

Divide both sides by 2

x=4

so the ladder reaches 4 feet on the wall

x+1 = 5

The ladder is 5 feet long

Hence, the ladder is 5 feet long.

Without the graph, we can speculate that it's a distance-time graph and could show how Zeke moved at different speeds, when he stopped or got lost, and when he arrived home, based on changes in the line over time.

Without the specific characteristics of the given graph, we can speculate using a generic distance-time graph. Let's say the 'y' axis represents the

distance

(in miles) from Zeke's home, and the 'x' axis represents time. At the start, Zeke is 30 miles away from home (top of the graph). If the line on the graph descends steeply, it means Zeke is going at a faster speed. A flat line would indicate Zeke has stopped or is not moving towards home, perhaps taking a rest. Sharp downward spikes could indicate periods where Zeke raced home at high

speeds

. If the line ascends, it could mean Zeke had to backtrack or got lost. The point at which the line reaches the bottom of the 'y' axis would be when Zeke arrives home. Making sense of a graph involves understanding its axes, the initial conditions and the interpretation of the changes in the line over time.

You're welcome:)

A scatter plot is the best choice of data display for Timothy to find a relationship between the ages of students and their shoe sizes. It shows a possible relationship between two variables, unlike histograms, box plots, and dot plots that display distribution or frequency of a single variable.

For Timothy to find if there is a relationship between the ages of students and their shoe sizes, the best choice of data display is a scatter plot. A scatter plot is a type of plot that is used to display values for typically two variables for a set of data. On a scatter plot, both horizontal and vertical axes are value axes that plot numeric data. Thus, it's most suitable for showing a possible relationship between two variables, such as ages and shoe sizes in this case. Other display methods, such as histograms, box plots, and dot plots, are more suitable for displaying distribution or frequency of a single variable rather than a relationship between two variables.

Answer:

d

Step-by-step explanation:

The correct answer is option C: 13 meters. Jacob and Sharon are approximately 13 meters apart.

To determine how far apart Jacob and Sharon are now, we first need to find their final positions and then calculate the distance between those points.

Step-by-Step Solution

→ Jacob's Movement:

He walked 3 meters north and then 4 meters west.

→ Final position of Jacob: (-4, 3).

Sharon's Movement:

→ She walked 5 meters south and then 12 meters east.

→ Final position of Sharon: (12, -5).

To find the distance between their final positions, we can use the Pythagorean theorem. The distance d between the points (-4, 3) and (12, -5) is calculated as follows:

→ d = √[(12 - (-4))² + (-5 - 3)²]

= √[(12 + 4)² + (-8)²]

= √[(16)² + (8)²]

= √[256 + 64]

= √320

= √(16 × 20)

= 4√20

= 4√(4 × 5)

= 8√5

≈ 13 meters

→ Thus, Jacob and Sharon are approximately 13 meters apart.

What do I help with?

Step-by-step explanation:

IF you put a picture we cannot see it/ At least I cannot see it.

d = kv

Substitute the 60 and 120 in.

120 = k * 60

k = 2

So, d = 2v

If v is 65, what is d?

2 * 65 = 130 miles

Final answer:

The distance Joseph travels before stopping for lunch varies directly with his speed. The equation that relates distance, d, and speed, v, is d = 2v. At a speed of 65 mph, Joseph would travel 130 miles before stopping for lunch.

Explanation:

Joseph's road trip scenario involves a direct variation between the distance traveled, d, and the speed, v, at which he travels. Since we know that he travels 120 miles at a speed of 60 mph, we can write the equation of direct variation as d = kv, where k is the constant of variation.

To find the value of k, we use the information given: d = 120 miles when v = 60 mph. So, we have 120 = k ×60.

To find k, we divide both sides by 60: k = 120 / 60 = 2. This tells us that the distance traveled varies with twice the speed. Thus, the equation relating d and v is d = 2v.

To determine how far Joseph would travel before stopping for lunch at a rate of 65 mph, we substitute v with 65 into the equation: d = 2 ×65, which calculates to d = 130 miles.

Jenny's future age would be expressed as ((x+4)/(2x+4))*100 percent of Benny's future age, where x is Jenny's current age.

To solve this problem, we first note that Benny is currently 200% of Jenny's age, meaning Benny's age is twice that of Jenny. So let's denote Jenny's current age as x - Benny's age will be 2x.

In 4 years, Jenny's age will be x+4 and Benny's age will be 2x+4. To calculate what percent of Benny's future age will Jenny's future age be, we have to divide Jenny's future age (x+4) by Benny's future age (2x+4) and then multiply by 100 to get the percentage. Therefore, Jenny's age will be ((x+4)/(2x+4))*100 percent of Benny's age.

Since we don't know their real ages, this is the most accurate answer we can provide, expressed as an algebraic equation. In real-life situation with the real ages known this equation would allow to find out what percent of Benny's age will Jenny’s age be in 4 years.

If Jenny's age is x, Benny's age is 2x. In 4 years, Jenny's age will be x+4 and Benny's will be 2x+4. To calculate what percent of Benny's age Jenny's age will be, we can use this formula: ((x+4)/(2x+4)) × 100.

Let's start by expressing Benny's age in terms of Jenny's age. If Benny's age is currently 200% of Jenny's age, then mathematically, we can say:

Benny's age = 200% of Jenny's age

B = 2 × x

Now, let's assume Jenny's age is represented as J. So, Benny's age is 2 × x.

If we want to find out what percent of Benny's age Jenny's age will be in 4 years, let's calculate it step by step.

In 4 years, Benny's age will be:

Benny's age in 4 years = Benny's current age + 4

Benny's age in 4 years = 2 × x + 4

Jenny's age in 4 years will be:

Jenny's age in 4 years = Jenny's current age + 4

Jenny's age in 4 years = x + 4

Now, let's find out what percent of Benny's age Jenny's age in 4 years will be:

Percent = (Jenny's age in 4 years / Benny's age in 4 years) × 100

Percent = (x + 4) / (2 × x + 4) × 100

This calculation will give us the percentage of Jenny's age compared to Benny's age in 4 years.

Answer:

Bill will earn more interest

He will earn $ 20,448.67 from his investment

Step-by-step explanations

Firstly let us calculate Jim's earnings based on simple interest

A = P(1 + rt)

Calculation:

First, converting R percent to r

a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

Solving our equation:

A = 15000(1 + (0.035 × 25)) = 28125

A = $28,125.00

The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim

Now let's us calculate bill's investment based on compound interest

Equation

A = P(1 + r)^t

A=15000(1+0.035)^25

A=15000(1.035)^25

A=15000*2.36324498427

A = $ 35,448.67

We see that Bill will earn

$ 20,448.67 from his investment
