Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

|  —                                 —  |

|   Point A = 1 * 30° = 30°    |         ⇒

|   Point B = 2 * 30° = 60°   |         ⇒          Only Extra Information

Answer:

A movie is $2.5

A video game is $6

Step-by-step explanation:

Pre-Solving

We are given that Ann had rented 2 movies and 5 video games for a total of $35.

We also know that she also rented 8 movies and 3 video games for a total of $38.

We want to know how much a movie costs, and how much a video game costs.

If a movie costs x dollars, then a video game costs y dollars.

Solving

This means that costwise, 2 movies will cost 2x, and 5 video games will be 5y.

8 movies will cost 8x, and 3 video games will cost 3y.

So, we will have two equations:

2x + 5y = 35

8x + 3y = 38

We now have this system of equations, which we can solve.

Let's solve this by elimination.

To eliminate, we need to clear one of the variables, and solve for the other one.

To do this, we need to make sure that one variable has the same coefficient with opposite signs (e.g. -3x and 3x). We might need to multiply one equation by a number in order to achieve this.

We can multiply 2x + 5y = 35 by -4.

-4(2x + 5y) = -4(35)

-8x - 20y = -140

We can rewrite the equations:

-8x - 20y = -140

8x + 3y = 38

They can be added together. The result will be:

-17y = -102

Divide both sides by 017.

y = 6

We found y, but now we need to find x.

We can substitute 6 as y into 2x + 5y = 35 or 8x + 3y = 38 to find x.

Taking 2x + 5y = 35 for instance:

2x + 5(6) = 35

2x + 30 = 35

Subtract 30 from both sides.

2x = 5

Divide both sides by 2

x = 2.5

Recall that x = price of a movie, and y = price of a video game.

Therefore, a movie is 2.5 dollars, and a video game is 6 dollars.

a movie is $2.50

and a snack is $6

Daniel wants to save money. The ratio of the amount of money in his savings account to the amount of money in his checking account was 1:6. Because Daniel is trying to get better at saving money, he moves money out of his checking account and into his savings account. Now the ratio of the amount of money in his savings account to the amount of money in his checking account is 4:3. If Daniel had $936 in his checking account before moving money, how much money does he have in each account after moving money?

100 points and brainliest if answered quickly!!!! Nick is investigating cell phone use in his hometown. So far, he has found that the residents used their cell phones for 217,470 minutes last year. This year, they used their cell phones for a total of 434,940 minutes. What is the percent of increase in annual usage?

Answers

To calculate the percent increase in annual usage of cell phones, we can use the following formula:

Percent increase = [(new value - original value) / original value] x 100

where the new value is the current year’s usage and the original value is last year’s usage.

In this case, Nick found that residents used their cell phones for 217,470 minutes last year and 434,940 minutes this year. So we can plug these values into the formula:

Percent increase = [(434940 - 217470) / 217470] x 100

Percent increase = 100%

Therefore, there was a 100% increase in annual usage of cell phones.

I hope that helps! Let me know if you have any other questions.

Answer:

6670 divided by 2=3335 SOOOO the answer is  :3335

Step-by-step explanation:

If they used 50 percent of their phone time, they're using half of it. Therefore, 1/2 of 6670 is 3335.   YW

Answer: B

The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?

Answers

Answer:

We can start by using the formula:

time = distance / speed

Let t be the time (in hours) for Tom and Katherine to meet.

Tom's distance = Tom's speed x time = 14t

Katherine's distance = Katherine's speed x time = 10t

Since they are riding towards each other, the total distance they cover is the sum of their distances:

Tom's distance + Katherine's distance = 42 miles

14t + 10t = 42

Simplifying:

24t = 42

t = 42 / 24

t = 1.75 hours

Therefore, Tom and Katherine will meet after 1.75 hours of riding.

They will meet in 1.75 hours
