Answer 1

Answer: Read the Explanation

Step-by-step explanation:

m<7 = 120

m<5 = 120

m<6 = 60

m<2 = 60

The reason why they are 60 is because they are supplementary angles to complete a straight line so like since 3 = 120 4 = 60 since its a straight line.

Kate, Alexia, and Trina just completed the 400-meter dash at the track meet. Kate finished the race 6 seconds faster than Alexia, while Trina finished the race 3 seconds faster than Kate. If their combined time was 2 minutes and 39 seconds, find each girl’s individual time.

Answers

Answer:

Kate = 52 seconds, Alexia = 58 seconds, Trina = 49 seconds

Step-by-step explanation:

A = K + 6

T = K - 3

K + A + T = 2 min 39 sec or 159 sec

K + (K + 6) + (K - 3) = 159sec

3K + 3 = 159sec

3K = 156sec

K = 52 sec

A = 52 + 6 = 58 sec

T = 52 - 3 = 49 sec

What is Expression?

A fine operation similar as deduction, addition, addition, or division is used to combine terms into an expression. In a fine expression, the following terms are used.

An absolute numerical number is appertained to as a constant.Variable- A symbol without a set value is appertained to as a variable. Term: A term can be made up of a single constant, a single variable, or a blend of variables and constants multiplied or divided.Coefficient In an expression, a measure is a number that's multiplied by a variable.

Given:

Expression: x+2x –8+3x+1 –2x

Now, simplifying the expression by taking like terms along.

x+2x –8+3x+1 –2x

= x+ 2x - 2x + 3x - 8 + 1

= x(1 + 2 - 2 + 3) -7

= x( 4) -7

= 4x -7

Answers

Answer:

A:Tina's. B: Gabby's

Step-by-step explanation:

Luckly the two people are using the same unit to measure both time (in weeks) and height (in inches), so no conversion needed.

At this point, let's start dealing with the questions.

A. They bought the plants at week 0.

For Tina, we calculate [tex]f(0) = 0+1.5 = 1.5[/tex]

For Gabby, we scout the table till we find week 0 and check the corrisponing value: it's (0; 1) Since 1 is smaller than 0, at start Tina plant was taller.

B. The easiest way would be to stare at Gabby's table for a bit, and notice that each increase is 2 more than the previous, and the progression starts at 1. We can write it as an equation as [tex]g(x) = 2x+1[/tex]. If you confront with Tina's growth, you can tell that Gabby's plant grows twice as fast - the slope is double. Else, you can see that even just after one week, Tina's plant will be 2.5 in tall, while Gabby's outgrew hers already. That's possible only if the plant is growing faster.

find the highest common factor of 9, 12 and 15

Answers

Hello there! :)

The highest common factor of 9, 12, and 15 is 3.

To find the HCF (also called the GCF) of two or more numbers, we list their factors:

9: 1, 3, 9

12: 1, 2, 3, 4, 6, 12

15: 1, 3, 5, 15

Can you see that 3 is their GCF?

Hope this helps!

Pls Help! Will Mark Brainliest!!!

Answers

Step-by-step explanation:

it is a bit unclear to me how the cups are stacked on each other.

are we building a pyramid or is it really just one line of cups stacked into each other ? the equation suggests the latter. so, I will continue with that assumption.

then each additional cup really adds only the height of the rim to the total height of the cup tower.

so, we want to find out for what smallest x is the equation delivering as y value 32,400 or more.

32,400 = 2.4x + 13.6

let's get rid of the decimals by multiplying everything by 10.

324,000 = 24x + 136

323,864 = 24x

x = 323,864/24 = 13,494.33333...

so, we need 13,495 cups to reach its height (just rounding it to 13,494 would still leave a tiny gap, so we need the 13,495th cup - there is no way to reach the height exactly).

The automobile has had more of an impact on American life than any other mode of transportation. The automobile has changed where people live, how people work, and how people view one another.In the early 20th century, people who worked in cities had to live in those cities. People lived in crowded apartments with very little room for their families. When the automobile became available to the masses, people were able to move outside of cities to live. The automobile is what led to the growth and development of the suburbs. People began building homes on the outskirts of cities. Soon these places became communities with roads, police stations, and restaurants. This helped create jobs in those areas. People could choose whether they wanted to drive their car to work in the city or closer to home. Either way, this choice and way of life would not be possible without the automobile.Cities were not the only areas affected by cars. The invention of the automobile helped increase farm production and distribution. Before the invention of the car, farmers used horses to travel. They were limited to only traveling 1520 miles. Now, with cars and later trucks, farmers could deliver their products many miles away. This meant that more people could buy their products, and the farmer could earn more money. This also meant that people could enjoy produce that was not locally grown. Cars did not only have positive impacts on American society. The invention of the car created a new class system for Americans. In the early 20th century, only the wealthy were able to own cars. Over time, cars became status symbols. Some cars were created simply as a symbol of wealth and class. That is still the case today. Cars have also created more pollution. The gasoline that cars need to run has negatively affected the air. The more cars there are, the more polluted the air becomes.The invention of the car has changed how people live in both positive and negative ways. This cannot be said for any other mode of transportation. Although ships and planes have made travel more convenient, they have not impacted a person's everyday life in the same way as cars.
