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!

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 =
tex]\frac{70}{4} =17.5[/tex] gallons.
Hence, the answer is 17.5 gallons.
Can someone please help, last question. Thanks

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!
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)

A = 3/4 M
Amari ran 12 miles
12 = 3/4 M Multiply by 4

48 = 3M Divide by 3
48/3 = M
M = 16
So Mary ran 16 miles.
X + 9 = 7
How do you move the constant to the right side and change it’s sign
Answers
Step-by-step explanation:
X + 9= 7
get x by itself you -9 on both sides
X + 9 = 7
- 9. -9
X = -2
You can throw the X to the right side and change to -X
9 = 7 - X
OR You can add both sides with -X
X + 9 - X = 7 - X
9 = 7 - X
Then you can do the same with 7 by throwing it to the left side and get -7
9 - 7 = - X
2 = - X
Now throw the -1 to the left side ( -X = -1X )
2(-1) = X
X = -2

Our second and final step is to divide both sides by 6.

If you are looking to solve y, the answer is 6 - 3x.
