Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 50 miles per hour and the other train travels at 60 miles per hour. How much time passes until the trains are 660 miles apart?
Answers
Let the first train travel east and the second train travel west.
The distance traveled by the first train is
x = (50 mi/h)*(n h) = 50n mi
The distance traveled by the second train is
y = (60 mi/h)*(n h) = 60n h
The distance between the two trains after n hours is
x + y = 50 n + 60n = 110n mi
Because this distance is 660 miles, therefore
110n = 660
n = 6 hours
Answer: 6 hours
if the perimeter of a rectangle is 318 inches, find the width and length. what's the answer?
Answers
let's consider that Length is n
Then width will be n+1
Perimeter of rectangle is equal to 2*(L+W) in this case
P = 2*(n + [n+ 1]) = 2*(n + n + 1) = 2(2n + 1)
P = 318
318 = 2(2n+1)
159 = 2n+1
159 - 1 = 2n
158 = 2n
79 = n
So this means that Length is 79 and Width is 80
or vice versa, Length is 80 and Width is 79
Tony rounded each of the numbers 1,210 and 1,148 to the nearest hundred. Which choice correctly compares the rounded numbers?
Answers
The process of rounding numbers 1,210 and 1,148 to the nearest hundred results in 1,200 and 1,100, respectively. Therefore, 1,200 is greater than 1,100.
Explanation:In Mathematics, rounding numbers is common practice for simplifying calculations. We are given the numbers 1,210 and 1,148, and we need to round them to the nearest hundred.
Let's round them:
1,210 rounded to the nearest hundred is 1,200.1,148 rounded to the nearest hundred is 1,100.So, when comparing the rounded numbers, 1,200 is greater than 1,100.

The price of gourmet coffee beans at the corner market has increased 10% per year over the past several years if the current cost is $40 per pound what did a pound of gourmet beans cost two years ago
Answers
Answer: $32.4
Step-by-step explanation:
Given : The price of gourmet coffee beans at the corner market has increased 10% (0.1) per year over the past several years.
The current cost is $40 per pound .
The exponential decay equation is given by :-
[tex]y=A(1-r)^x[/tex], where r is the rate of decay and A is the initial amount and x is the time period.
Put A = 40 , r= 0.1 and t=2, we get
[tex]y=40(1-0.1)^2=\$32.4[/tex]
Hence, the cost of a pound of gourmet beans two years ago= $32.4

Solve for x. 4−(2x+4)=5
A x=6
B x=−10
C x=−52
Answers
4 - 2x - 4 = 5
-2x = 5
x = - 5/2 <==
The solution for x in the equation 4 - (2x + 4) = 5 is x = -5/2. So, the correct choice is x = -5/2. Option c is the correct choice.
To solve for x in the equation 4 - (2x + 4) = 5, follow these steps:
1. First, simplify the equation by combining like terms. Start by removing the parentheses by distributing the negative sign:
4 - 2x - 4 = 5
2. Now, simplify further by combining the constants on the left side of the equation:
(4 - 4) - 2x = 5
0 - 2x = 5
3. Next, isolate the variable x by getting rid of the -2 coefficient. To do this, divide both sides of the equation by -2:
(0 - 2x) / -2 = 5 / -2
0 / -2 - (2x / -2) = -5/2
0 + x = -5/2
4. Finally, simplify:
x = -5/2
So, the solution for x is:
x = -5/2
So, Option c is the correct choice.

B. Commutative Property
C. Opposite of a Sum Property
Answers
The answer is Commutative Property.
Answer:
Option B is correct.
Commutative property is used here.
Explanation:
Commutative Property states that we can add any number in any order, we will get the same result i.e, a+b = b+a.
let a = -4.8 and b = (3.2+(-1.6))
then, using commutative property we have;
a+b=b+a then,
−4.8 + (3.2 + (−1.6)) = (3.2 + (−1.6)) + (−4.8).
For a Circle of radius is 5 feet, find the arc length s subtended by a central angle of 42 degrees
Answers
The arc length subtended by a central angle of 42 degrees in a circle of radius 5 feet is 3.665 feet.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The formula for arc length is given by:
s = rθ
where s is the arc length, r is the radius of the circle, and θ is the central angle subtended by the arc in radians.
To use this formula, we first need to convert the central angle from degrees to radians:
θ = (π/180) × 42 = 0.733 radians
Now we can plug in the values of r and θ into the formula to get:
s = 5 × 0.733
= 3.665 feet
Therefore, the arc length subtended by a central angle of 42 degrees in a circle of radius 5 feet is 3.665 feet.

Answers
Answer:
The given equation is false
Step-by-step explanation:
Given equation : E= 5.7q+8.8
To show : It is true or false
Solution : Cost of transportation and supplies is fixed = $14.50
Cost of labor and groceries for each family meal =$8.80
Let x is the number of meals
so, according to the question Expense function for x number of meals is
Expense function = x(cost of labor and groceries for 1 family meal)+ cost of transportation and supplies(fixed)
E= 8.80x+14.50 which is the required equation.
Therefore, given equation is false.
