x=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7

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)

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

Can someone please help, last question. Thanks

Answers

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!

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.

Hope this helped!

Make y the subject of the formula x=a-2by²

Answers

Answer:

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Step-by-step explanation:

Given

x = a - 2by² ( add 2by² to both sides )

x + 2by² = a ( subtract x from both sides )

2by² = a - x ( divide both sides by 2b )

y² = [tex]\frac{a-x}{2b}[/tex] ( take the square root of both sides )

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Suppose you are deciding whether to take a train or a car to travel 3,000 miles across a country. The train travels at 95 kilometers an hour, while a car will travel 65 miles per hour on average. Which mode of transportation will take less time? Note that 1 mi=1.6 km.

Answers

Answer:

The car

Step-by-step explanation:

Train:

1mi = 1.6 km

95km = 95/1.6 = 59.375 km

95km/h = 59.375mi//h

Car

     65mi/h

Comparative:

65 > 59.375

then:

the car is more faster

Answer:

The answer is A : the car will take less time because it travels at a faster speed. the train will travel at 95/1.6=59.03 while the car travels at 65
