Answer:

A) a= 123   b= 123   c= 57

B) d= 98   e= 98   f= 98

C) g= 75   h= 75

Step-by-step explanation:

The ones that have the same angle measurement are corresponding angles, meaning that they have -well- the same measurement.

Adjacent angles are how I figured out the measurements. If you have one angle, the angle next to it will form a straight line, or 180 degrees. You just subtract that measurement to 180 and get the other angle.

Answer:

G= 75 H=75

Step-by-step explanation:

Ok, so with these the lines are marked as parallel. All lines are equal to 180 degrees, so with the given information that one of the angles are 75 degrees, you can subtract 75 from 180 to get 105. Since both g and h did not require that, it was not entirely necessary for me to say that, but I hope that it can be helpful for you. But, because the lines are parallel, it means that the other side also has a 75 degree angle as well as a 105 degree angle. Just looking at the size of the angle that's labeled can help too. the smaller angle is 75. Since the lines are parallel, you can just find the smaller angles and mark them as 75 as well. Hope that was helpful to you!

Jenna bought 5 reams of paper at the store for a total of $21. The tax on her purchase was $1. Solve 5x + 1 = 21 to determine the price for each ream of paper.

Answers

Answer:

$4

Step-by-step explanation:

From the question we have it that jenna bought the 5 reams of paper at a price of 21

The tax on this was $1

The total cost of the paper minus tax = $20

Cost of 1 team = total cost of paper / quantity

= 20/5

From the equation

5x +1 = 21

5x = 21 -1

5x = 20

X = 20/5

X = $4

Therefore we have The cost of a team of paper to be equal to $4

Amy and her sister are making lemonade for the school dance. Their recipe makes 2 quarts of lemonade. If they make 35 times the recipe how many gallon

Answers

Answer:

Amy and her sister will have 17.5 gallons of lemonade for the school dance.

Step-by-step explanation:

The sister's recipe makes 2 quarts of lemonade. As they want to make 35 times more, so total number of quarts made will be =

quarts

Now, 4 quarts has 1 gallon.

So, total number of gallons in 70 quarts will be =

Hence, the answer is 17.5 gallons.

if the selling price of 16 water bottles is equal to the cost price of 17 water bottles find the gain percent earned by the dealer

Answers

Answer:

let cp of 17 water bottle is x

cp of 1 water bottle = x/17

from the question

sp of 16 water bottles = x

sp of 1 water bottle = x/16

profit = sp -cp

        = x/16 - x/17

      =  x/272

profit % = profit /cp * 100%

            = (x/272)/ (x/17) * 100%

= 6.25%

Of Q is the midpoint od RP, Find the coordinates of R if P(9,-2) and Q (4,5)

Answers

Answer:

(-1,12)

Step-by-step explanation:

let R be(x,y)

Q(4,5)=midpoint

R(x,y)=(x1,y1)

p(9,-2)=(x2,y2)

now,

(4,5)= x1+x2/2 , y1+y2/2

(4,5)= x+9/2 , y-2/2

so,

x+9/2=4              y-2/2=5

x+9=8                  y-2=10

x= -1                      y=12

therefore, R(x,y)= (-1,12)

Rosea drives her car 30 kilometers to the train
station, where she boards a train to complete her trip. The
total trip is 120 kilometers. The average speed of the train is
20 kilometers per hour faster than that of the car. At what speed
must she drive her car if the total time for the trip is less than
2.5 hours?

Answers

Answer:

>34.88km/h

Step-by-step explanation:

Because we have two unknown values in this question (speed of train and speed of car), we will need two equations to solve it.

Firstly, we can make a big equation for time in terms of the vehicle speeds. Time = distance / speed, so if we use t for the train speed and c for the car speed, we get this equation for speed:

30/c + 90/t = 2.5

Here the 30 is the distance traveled by the car in km and the 90 is the distance traveled by the train in km (120 - 30 = 90).

We also know that the train speed was 20km/h faster than the car speed so our second equation is:

c + 20 = t

So now we can substitute this in the big equation so we only have one variable to solve for:

30/c + 90/(c+20) = 2.5

Now to solve this, this first step is to get rid of the fractions, which we can do by multiplying all the terms by the lowest common factor of the two denominators which is c(c+20):

(30/c)*c(c+20) + (90/c+20)*c(c+20) = 2.5

This simplifies to:

120c+600=2.5c^2+50c

and then into the quadratic equation:

2.5c^2-70c-600=0

This can be solved with the quadratic formula or a solver/calculator, and yields the solutions:

c=−6.88, 34.88 (both to 2dp)

We can eliminate the negative solution because speed cannot be negative meaning that Rosea must drive her car at the speed of at least/greater than 34.88km/h if she wants the total trip to be less than 2.5 hours.

New Technology Leads to Bigger CitiesIn the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in GreatBritain, a fast development of society following the introduction of machines. The United States was slower than Great Britain tofully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for theirfamilies as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry,More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United Statesalso settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildingsfor living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urbanareas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast andMidwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and wouldsoon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, thefactories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By2007, more Americans lived in or near cities than they did in rural areas.Select a sentence from the body of this article that can be removed without affecting the author's explanation.
