Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train A heading towards station A, and train B heading towards station B. Train A reaches station A after 4 h. Train B reaches station B after 3 1/2 h. Station A and Station B are 562.5 mi apart.
What are the rates of the trains?
Answers
Answer:
since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.
Train A:
da = R * 4
Train B:
db = R * 3.5 (using 3.5 instead of 3 and 1/2)
Solve for R:
R * 4 + R * 3.5 = 562.5
7.5 * R = 562.5
R = 75
The trains are traveling at 75 miles per hour.
Step-by-step explanation:
Answer:
speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2
speed = 585/(13/2) = 90 miles per hour.

The high temperatures, in degrees Fahrenheit, of 10 U.S. Cities during a day in October are listed below. 72, 50, 54, 66, 58, 79, 54, 99, 40, 68 What is the range of the temperatures? A. 54°F B. 59°F C. 62°F D. 64°F
Answers
Answer: B. 59°F
Step-by-step explanation:
Range = Maximum - MInimum.
From the given temperatures, Maximum temperature = 99 degrees Fahrenheit
Minimum temperature = 40 degrees Fahrenheit
Range = Maximum temperature - Minimum temperature
i.e. Range =99-40 = 59 degrees Fahrenheit
Hence, the range of the temperatures = 59°F i.e. B is the correct option.

find the area of the isocele triangle formed by the points of intersection of parabolas y=-x^2+9 and y=2x^2-3 and the origin
Answers
Answer:
[tex]10\ \text{sq. units}[/tex]
Step-by-step explanation:
The parabola's are
[tex]y=-x^2+9[/tex]
[tex]y=2x^2-3[/tex]
So
[tex]-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2[/tex]
[tex]y=-x^2+9=-(2)^2+9\\\Rightarrow y=5[/tex]
[tex]y=-(-2)^2+9=5[/tex]
So, the points at which the parabola's intersect each other is [tex](2,5)[/tex] and [tex](-2,5)[/tex]
The three points of the triangle are [tex](2,5)[/tex], [tex](-2,5)[/tex] and [tex](0,0)[/tex]
Area of a triangle is given by
[tex]A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}[/tex]
Area of the triangle formed is [tex]10\ \text{sq. units}[/tex].

In ΔEFG, f = 42 inches, e = 39 inches and ∠E=43°. Find all possible values of ∠F, to the nearest degree.\
Answers
Answer:
The angle F = 47.25°
Step-by-step explanation:
Step(i):-
Given that f =42inches and e = 39 inches
Given that ∠E = 43°
By using sine rule
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{C}{sinC} = 2R[/tex]
[tex]\frac{e}{sinE} = \frac{f}{sinF}[/tex]
⇒ [tex]\frac{39}{sin43} = \frac{42}{sinF}[/tex]
Cross multiplication , we get
⇒ 39 sin F = 42 × sin 43°
[tex]sin F = \frac{42 X 0.68199}{39}[/tex]
⇒ sin F = 0.734459
Step(ii):-
⇒ sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)
⇒ F = 47.25
The angle F = 47.25°

On last week's math test, 32 students received passing grades and 16 students did not
receive passing grades. What is the ratio of the number of students who passed the test to
the total number of students who took the test?
A
11 / 1
B
2/3
C
3/2
D
2/1
Answers
Answer:
Option B. The ratio of the number of students who passed the test to
the total number of students who took the test is 2/3
Step-by-step explanation:
Firstly, we have to find the total number of students who took the test, we can do that by adding the number of students who passed and the number of students who did not pass, so ...
32 + 16 = 48
Now we just write down the ratio between the number of students who passed the test and the total number of students who took the test. So we get
32/48
Now we just simplify and get...
2/3
