Two trains leave stations 532 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 100 miles per hours. How long will it take for the two trains to meet?
Answers
The two trains will meet in 2.4 hours.
What is the distance?Distance is defined as the product of speed and time.
We have been given that two trains depart from stations 532 miles apart at the same time and head in the opposite direction. The first train runs at 90 miles per hour, while the second at 100 miles per hour.
Let's assume x distance 90 mph train traveled
Then (532 - x) is the distance 100 mph train traveled
Travel time = distance/speed (equal in both directions)
⇒ x/90 = (532 -x)/100
⇒ 100x = 90× 532 - 90x
⇒ 100x + 90x = 47880
⇒ 190x = 47880
⇒ x = 47880/190
⇒ x = 252
So travel time = 252/90 = 2.4 hrs
Therefore, the two trains will meet in 2.4 hours.

Then the "a" and "b" in the expression -b/(2a) represent the coefficients of the squared term and the linear term, respectively. In your quadratic expression, the variable is "t", not "x", but that makes no difference. You have
a = -16
b = 96
Then the time (t) at the maximum height is
t = -b/(2a)
t = -96/(2(-16)) = 96/32 = 3
The ball is highest 3 seconds after being fired.
(b) Evaluating h for t=3, we get

A 12-foot ladder is leaning against a wall. The distance from the base of the wall to the base of the ladder is feet. Given this information, what can be determined about the triangle formed by the ground, wall, and ladder? Check all that apply.
Answers
We are given the length of the ladder and the distance of the base of the ladder from the wall. With that we can solve for the height of the triangle as well as the angle of inclination wrt to the floor and foot of the ladder or the wall to the tip of the ladder.
Pythagorean's theorem provides for the following formula
Square of hypotenuse (longest side of the triangle) equals the sum of the squares of the two other sides for right triangles.
Thus
Length of ladder being the hypotenuse we have below equation
Hypotenuse = 12
Distance from the base to the foot of ladder = 1 foot/feet
height = ?
12² = 1² + h²
h = √144-1
h=√143
Solving for inclination with respect to wall to tip of the ladder we can use rule of sine for right triangle
sineФ = opposite side / hypotenuse
sineФ = 1/12 = 0.083333
Ф = sin^-1 or inverse sine of 0.083333
Ф = 4.78017268 degrees
Note : If the distance between the base is not interpreted correctly, just change the value and plugin to the equation to get the result.

a man owned 75 shares of stock worth $50 each the corporation declared a dividend of 8% payable in stock how many shares did he then own
Answers
After receiving an 8% stock dividend on his initial 75 shares, the man will own a total of 81 shares.
Explanation:The question is asking how many shares the man will own after a corporation where he holds stock declared a dividend payable in stock. The man initially owned 75 shares of stock, each worth $50, and the corporation declared an 8% dividend. To find out how many additional shares he receives as a dividend, we calculate 8% of his 75 shares:
Additional shares = 8% of 75 = 0.08 × 75 = 6 shares.
The man will then own his original 75 shares plus the 6 additional shares, for a total of:
Total shares owned = 75 + 6 = 81 shares.

In a family with 8 children, excluding multiple births, what is the probability of having 7 boys and 1 girl, in any order? assume that a boy is as likely as a girl at each birth
Answers
The probability of having 7 boys and 1 girl in a family with 8 children is 1/128.
Explanation:To find the probability of having 7 boys and 1 girl in a family with 8 children, we can use the concept of combinations. There are 8 children in total, and we want to choose 7 boys and 1 girl from them. The probability of having a boy or a girl at each birth is 50%, so we can use the binomial coefficient to calculate the probability. The formula for the binomial coefficient is C(n, k) = n! / (k!(n-k)!), where n is the total number of children and k is the number of boys we want. Plugging in the values, we get C(8, 7) = 8! / (7!(8-7)!) = 8. Therefore, the probability of having 7 boys and 1 girl in any order in a family with 8 children is 8 / 2^8 = 1 / 128.
There is a game at the carnival that costs $20 to play. There are two outcomes: either you win $100 , or you lose. To play you roll a die. If a six appears you win; all other rolls you lose. if 1000 people played this game during one afternoon what would you expect to be the outcome?
A. the game earns $3330
B. the game earns $1660
C. the game loses $3330
D. the game loses $1660
Answers
Outcome on losing = $20
Probability of winning = 1/6
Probability of losing = 5/6
Expected Value = 1/6 (80) +5/6(-20) = -3.333
This shows on average from each game, the game earns $ 3.333.
So, if 1000 such games are played, the game will earn 1000 x 3.33 = $3330
So, the answer to this question is option A
Correct answer is Option(A) . The game earns $3330
Carnival Game Expected Outcome
To determine the expected outcome, we first need to calculate the expected value of playing this game once.
The cost to play is $20. If a six is rolled, the player wins $100; otherwise, they lose their $20.
Calculations:
Probability of rolling a six = 1/6Probability of not rolling a six (1, 2, 3, 4, or 5) = 5/6Expected value (EV) for one game:
EV = (1/6 x ($100 - $20)) + (5/6 x (-$20))EV = (1/6 x $80) + (5/6 x -$20)EV = $80/6 - $100/6EV = -$20/6EV ≈ -$3.33This means that on average, each player loses approximately $3.33 per game.
Outcome for 1000 Players
If 1000 people play the game, the total expected loss for the players will be:
Total Expected Loss = 1000 x EVTotal Expected Loss ≈ 1000 x (-$3.33) = -$3330Therefore, the game earns approximately $3330.

The endpoints of a line segments are at the coordinates (-6,3,4) and (4,-1,2) what is the midpoint of the segment
Answers
Explanation:
The coordinates of the mid point are calculated by dividing the sum of each pair of corresponding coordinates by 2.
This is how you calculate the mid of each coordinate separately:
1) x-coordinate:
mid x-coordinate = (- 6 + 4) / 2 = -2 / 2 = - 1
2) y-coordinate
mid y-coordinate = (3 - 1) / 2 = 2 / 2 = 1
3) z-coordinate
mid z-coordinate = (4 + 2) / 2 = 6 / 2 = 3
So, the midpoint is (-1, 1 , 3)
one day a store sold 12 sweatshirts white one cost $9.95 and yellow ones cost $12.50. In all 147.45 worth of sweatshirts were sold how many of each color were sold?
Answers
y= # of yellow sweatshirts
STEP 1:
set up quantity and cost equations
QUANTITY EQUATION
x + y= 12
COST EQUATION
$9.95x + $12.50y= $147.45
STEP 2:
solve for one variable in quantity equation
x + y= 12
subtract y from both sides
x= 12 - y
STEP 3:
substitute x value in step 2 in cost equation
$9.95x + $12.50y= $147.45
9.95(12 - y) + 12.50y= 147.45
multiply 9.95 by parentheses
(9.95*12) + (9.95*-y) + 12.50y= 147.45
119.40 - 9.95y + 12.50y= 147.45
combine like terms
119.40 + 2.55y= 147.45
subtract 119.40 from both sides
2.55y= 28.05
divide both sides by 2.55
y= 11 yellow
STEP 4:
substitute step 3 x value in either equation
x + y= 12
x + 11= 12
x= 1 white
CHECK:
$9.95x + $12.50y= $147.45
9.95(1) + 12.50(11)= 147.45
9.95 + 137.50= 147.45
147.45= 147.45

What is the y-intercept of the quadratic function fx) (x- 6)(x-2)?
Answers
To find the y-intercept of a quadratic that is in factor formed follow the steps below:
First take the factor form and put it into standard quadratic form
Standard quadratic form:
[tex]ax^2 + bx + c[/tex]
To put the the factor form of a qudratic into standard form, we use the foil method
(x-6)(x-2) = [tex]x^2 - 8x +12[/tex]
Now to find the y-intercept, input 0 where the x is located:
[tex]f(x) = x^2 - 8x +12[/tex]
[tex]f(0) = 0^2 - 8(0) +12[/tex]
[tex]f(0) = 12[/tex]
y-intercept = (0,12)
Why did I use 0? Remember the y-intercept is where the line crosses the y axis so this means the x value of the y intercept is always = 0. Also, not, to find the y-intercept, you could of just multiplied the 6 and 2 in the factored form to get the 12 and since you know that the x is always 0 at the y-intercept, you know that the y-intercept is at (0,12)
Option 2
Input 0 for x in f(x) = (x-6)(x-2)
f(x) = (x-6)(x-2)
f(0) = (0 - 6)(0 - 2)
f(0) = (6)(2) = 12
x = 0
f(0) = y = 12
y-intercept = (0,12)

Marcus has a pool that can hold a maximum of 4500 gallons of water. The pool already contains 1500 gallons of water. Marcus begins to add more water at a rate of 30 gallons per minute. Write an inequality that shows the number of minutes, m, Marcus can continue to add water to the pool without exceeding the maximum number of gallons.
Answers
4500 - 1500 = 3000
Because we need to represent an inequality:
30m = 3000
Divide both by 30:
m = 100
It will take 100 minutes
Answer:
Inequality is m ≤ 1000
Step-by-step explanation:
Capacity of the pool to hold the maximum water is = 4500 gallons of water.
Pool is already having 1500 gallons of water so remaining volume of the pool that can be filled is = 4500 - 1500 = 3000 gallons
Marcus begins to add 30 gallons water per minute and it takes "m" minutes to fill the remaining volume.
So amount of water required = 30m gallons
There is a condition that Marcus continues to add water without exceeding the maximum amount of water.
This means remaining amount "3m gallons" will be never cross the limit of "3000 gallons" of remaining volume of water.
Now we can form the inequality as 3m ≤ 3000
or m ≤ 1000
Therefore, answer is m ≤ 1000
