he equation of the line of best fit relating age (in years) and the median height (in cm) of boys is given.

y = 6.5x + 75.5
Which statement below best interprets the slope in the context of the problem?

Answers

Answer 1

Answer:

proof: answer is 2/13

1 / 6.5 = m

m = 0.153846154

10/65 = m

m = 2/13

2/13 = m

m = 0.153846154

Therefore we could show multiplication proof

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Step-by-step explanation:

See attached graph of y = 6.5x+75.5

plotting the graph

1. Mark y intercept at 75.5 as given in the equation

2. find the slope to whole numbers

m =  10 across / 65 across = 6.5 slope

Mapping Pythagoras   10^2 +65^2 = c^2

sqrt 100 + sqrt 4225 = c^2

c^2 = sqrt 4225 = 65.7647322 = 65.8

0.7647322 / 65 = 0.0117651108 = 100th

65 + 0.0117651108 = 65.011765.....

Therefore 10 across / 65.0118  down

or 10 across  / 65 down is another way to graph, as seen on graph.

m = 10/65  =   m = 2/13

2 x 5 = 10

13 x 5 = 65

Answers

46.6 feet

Step-by-step explanation:

P = 2ℓ + 2w

P = 2(ℓ + w)

P = 2(15.5 + 7.8)

A salesperson works 40 hours per week at a job where has two options for being paid. Option A is an hourly wage of ​23$. Option B is a commission rate of ​10% on weekly sales. How much does need to sell this week to earn the same amount with the two​ options

Answers

Answer:

$9200

Step-by-step explanation:

Since he works 40 hours a week and would make $23 for every hour with option A, we just multiply 40 by 23

40 x 23 = 920

This means 10% of the sales will need to equal to 920

Let x = sales

We multiply x by 0.1 to get 920

0.1x = 920

Divide both sides by 0.1

0.1x/0.1 = 920/0.1

x = 9200

find the length of the hypotenuse of the right triangle. leave your answer in simplest radical form. not drawn to scale. ​

Answers

Two ways to solve this:
1) Notice that this is a 45-45-90 triangle, meaning the ratio of sides and hypotenuse is 1:1:sqrt(2)

Since the legs are 4, that would mean the hypotenuse would be 4*sqrt(2)

2) Pythagorean theorem: a^2 + b^2 = c^2

4^2 + 4^2 = 32
Sqrt(32) = 4*sqrt(2)

3. In the diagram below AB' is the image of AB after a reflection in AC. If mBAC4x7 and mBAB '  64 , then which of the following is the value of x?
(1) 6.25 (3) 14.25 (2) 12.5 (4) 18.75

Answers

When a line or shape or point is reflected, it must be reflected over a line.

The value of x is (b) 14.25

Reflection is a rigid transformation;

This means that:

[tex]\mathbf{\angle AC = \angle AB}[/tex]

So, we have

[tex]\mathbf{4x + 7 = 64}[/tex]

Subtract 7 from both sides

[tex]\mathbf{4x = 57}[/tex]

Divide both sides by 4

[tex]\mathbf{x = 14.25}[/tex]

Hence, the value of x is (b) 14.25

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.

How fast did Car A travel?

(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)

Enter your answer in the box.

Answers

Answer:

We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.

x/2.4 = 22 + y/4

Since y = x, then:

x/2.4 = 22 + x/4

Solving for x, we obtain:

x= 132 meters traveled by both cars

Therefore, Car A has a speed of 55 mph.

Step-by-step explanation:

Answer:

Step-by-step explanation:

x/2.4 = 22 + y/4

Since y = x, then:

x/2.4 = 22 + x/4

y = 3x – 10


y = 3x


y = 3x – 6


y = –3x + 8

Answers

Answer:

y = 3x - 6

Step-by-step explanation:

(1, -3) (7, 15)

Step 1. Find the slope

Slope = 3

Step 2. Create the equation of the slope then use a point and plug it in as terms of x and y with a y-intercept at the end

y = 3x + b

(15) = 3(7) + b

15 = 21 + b

15 - 21 = b

b = -6

Thus, the equation of the line is y = 3x - 6

Ginny the Dog: A Hero Among HeroesHeroes come in many shapes and forms, but they all do uncommon things in unusual situations. They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.What is the main idea of the essay?A Ginny devoted her life to rescuing needy and endangered cats.B Ginny is a loyal and happy dog.C Ginny made a good impression on her owner from the first day.D Ginny makes all other hero dogs look like amateurs.
