Linda has outgrown the bike she rode when she was small. So, for her twelfth birthday, her parents surprise her with a five-speed Blaze Rider 2000! Linda has never had a bike with multiple speeds before, and she is eager to learn how it works. She starts by testing the middle speed. There is a proportional relationship between the number of times Linda pedals, x, and the number of times the wheels rotate, y. The equation that models this relationship is y=3x. How many times do the wheels rotate when Linda pedals 2 times? Write your answer as a whole number or decimal

Answers

Answer:

6 times

Step-by-step explanation:

Given the proportuonal relationship between exists between the number times Linda pedals (x) and the number of times wheels rotate (y) as ;

y = 3x

How many times do the wheels rotate when Linda pedals 2 times

Here, x = 2

From ; y = 3x

y = 3(2) = 6

Hence, wheel rotates 6 times.

Sofia has an action figure collection. She keeps 185 of the action figures on her wall, which is 37% of her entire collection. What is the total number of action figures in Sofia's collection?

Answers

Answer:

222

Step-by-step explanation:

Answer:

500 figures.

Step-by-step explanation:

We know that 185 figures is 37% of her entire collection.

Let c represent the total amount of figures.

Since 185 is 37% or 0.37 of her total collection, we can write the equation:

[tex]0.37c=185[/tex]

Remember that the keyword of tells us it's multiplication.

Therefore, to find the number of figures in her total collection, divide both sides by 0.37:

[tex]c=\frac{185}{0.37}[/tex]

Evaluate. Use a calculator. So:

[tex]c=500[/tex]

Sofia's total collection has 500 figures.

Step-by-step explanation:

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of the given line is y=(4/3)x-4.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The slope of the line can be calculated with the two points that are present on the line, in this case, these points are (3,0) and (0, -4). Therefore, the slope is,

Slope, m = (-4 - 0)/(0 - 3) = -4/-3 = 4/3

The y-intercept of the line is -4, therefore, the equation of the line can be written as,

y = mx + c

y = (4/3)x - 4

Hence, the equation of the given line is y=(4/3)x-4.

If ∠1 and ∠2 are complementary, m∠1 = (8x-6)°, and m∠2 = (14x+8)°
URGENT PLEASE HELP

Answers

Answer:

Step-by-step explanation:

[tex]\large\underline{\bf\red{Solution:-}}[/tex]

Given : ∠1 + ∠2 = 90° ( complementary )

To Find : The value of x & the two angles .

And , m∠1 = ( 8x - 6 ) ° & m∠2 = ( 14x + 8 )° .

On adding the two Angles their sum will be 90 ° since they are two complementary angles .

⇒ ( 8x - 6 )° + ( 14x + 8 )° = 90° .

⇒ 22x + 2° = 90° .

⇒ 22x = (90 - 2)°

⇒ 22x = 88° .

⇒ x = 88°/22 .

x = 4° .

Hence the value of x is 4° .

So ,

First angle = 8x - 6 = 8×4-6=32-6=26°Second angle = 14x +8 = 14(4)+8 = 56+8 = 64° .

Write and then evaluate an addition expression to determine Jayvon's current points.

Answers

Answer:

33.6+(-5.5)=28.1

Step-by-step explanation:

Since positive times negative is equal to negative, we can multiply -5.5 by an addition symbol, making it an addition problem, and making it the same expression.

To evaluate the expression, we can do 33.6-5.5.

When adding or subtraction decimals, write it stacked like a normal problem, and line up the decimal places, like so.

33.6-

 5.5

Then you can subtract normally, getting 28.1

What is the equation of the line that passes through the point (-5,6) and has a slope of 0

Answers

y = 0x + 6 or y = 6
you substitute the points into the equation y=mx+b, m is the slope and b is the y-intercept. Solve for anything you need or missing from the equation. Original equation is y=mx+b so you only have to put in the m and b.

The equation of the line that passes through the point (-5,6) and has a slope of 0 is y = 6

Equations are expressions that related two or more expressions together using an equal sign.

The formula for finding the equation of a line in point-slope form is expressed as:

y-y0 = m(x-x0) where:

m is the slope(x0, y0) is the intercept

Given the following

m = 0

(x0, y0) =  (-5, 6)

Substitute the given values into the formula

y - 6 = 0 (x - (-5))

y - 6 = 0 (x + 5)

y - 6 = 0

y = 6

Hence the equation of the line that passes through the point (-5,6) and has a slope of 0 is y = 6

Born into an upper class family, Caesar and some of his relatives held important positions in the government. 409 years before Julius was born the Republic of Rome was a dangerous time. The republic was being governed by a Senate. Senates were elected by the people of Rome. When Rome was growing in population, it made it more difficult to govern. Senators fought amongst themselves for more power. The working class became frustrated with the noble class governing. It lead to civil wars in the republic. Caesar aligned himself with people who were against the nobility. He started his share in politics as an advocate in 78 BCE. He decided to study oratory in Rhodes, Greece in 76 BCE. During the trip he was captured by pirates. They held him for ransom money. Caesar got the ransom money himself and got released. Instead of retiring to his homeland, Caesar decided to organize a naval force that captured the pirates. Two years later, in 74 BCE, with no official place in the Roman government or army, Caesar decided to organize a private army. This army fought off the king of Pontus who was declaring war on the Romans. All of these events made Caesar well known and a public disagreement. He moved his way through different political positions in a dishonest way. Although Roman Senates disliked Caesar, they appointed him Farther Spain. In 59 BCE, Caesar was elected into consul no matter the Senates attempts to prevent it. Consuls had significant power and Caesar took advantage of this power. He formed the first triumvirate. He combined his power with Pompey and Crassus. Crassus was a wealthy politician and Pompey was a war hero who was not liked among the Senates. Caesar decided to pay off Pompeys soldiers by giving them land to reward Pompey. People organized a riot because they disliked the idea. These riots caused chaos. Caesar took this as a distraction to get his way. This distraction allowed Caesar to become governor of Gaul. Around 58 and 50 BCE, Caesars military conquered all of Gaul. During that time, Caesars triumvirate was falling apart while he was becoming very successful. Caesar gained enemies because he was becoming successful. Caesar thought the only way to protect himself was to seize the rest of Rome. In 49 BCE he began a civil war after leading his troops across the Rubicon River into Italy. In 46 BCE he made himself a dictator of Rome. He continued defeating his enemies before returning into Rome after a year. When he made his return he adopted his great nephew, Augustus. Caesar never had a son of his own. Caesar revised the Roman calendar and made Senates more representative. He made many foreigners, citizens of Rome. Although Caesar tried his best in protecting himself, Caesars old enemies and some of his supporters devised a plan to assassinate him. On March 15, 44 BCE, Caesars enemies killed him in the Senate House. Augustus, Caesars nephew, eventually took over in 32 BCE. Caesar made a long line in history of emperors.
