Two trains leave stations 306 miles apart at the same time and travel toward each other. one train travels at 75 miles per hour while the other travels at 95 miles per hour. how long will it take for the two trains to meet?
Answer: It will take 1.8 hours for the two trains to meet.
Step-by-step explanation:
Since we have given that
Speed of one train = 75 mph
Speed of other train = 95 mph
Since they travel towards each other.
so, Relative speed = 75+95 = 170 mph
Distance between them = 306 miles
We need to find the time taken:
So, it becomes,
[tex]time=\dfrac{Distance}{Speed}\\\\Time=\dfrac{306}{170}\\\\Time=1.8\ hours[/tex]
Hence, it will take 1.8 hours for the two trains to meet.

Lena will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $50 and costs an additional $0.50 per mile driven. The second plan has no initial fee but costs $0.70 per mile driven. For what amount of driving do the two plans cost the same? What is the cost when the two plans cost the same
The two plans cost the same when Lena drives 250 miles, resulting in a cost of $175 for both plans, as per the given linear equation.
A linear equation is a mathematical expression that represents a straight line relationship between variables, typically in the form of ax + b = 0.
The two plans cost the same when the amount of driving satisfies the equation:
50 + 0.50x = 0.70x
Where:
50 represents the initial fee for the first plan,
0.50x represents the cost per mile for the first plan, and
0.70x represents the cost per mile for the second plan.
Now, let's solve for x:
50 + 0.50x = 0.70x
Subtract 0.50x from both sides:
50 = 0.20x
Now, divide both sides by 0.20:
x = 50 / 0.20
x = 250
So, the two plans cost the same when Lena drives 250 miles. To find the cost at this point, plug x = 250 into either plan:
For the first plan:
Cost = 50 (initial fee) + 0.50 (cost per mile) * 250
Cost = $50 + $125
Cost = $175
For the second plan:
Cost = 0.70 (cost per mile) * 250
Cost = $0.70 * $250
Cost = $175
So, when Lena drives 250 miles, both plans cost $175.

If MNO ~XYZ,then what corresponding parts are congruent
Final answer:
In similar triangles MNO and XYZ, corresponding angles are congruent (M with X, N with Y, O with Z) and corresponding sides are in proportion (MN to XY, NO to YZ, MO to XZ).
Explanation:
If triangles MNO and XYZ are similar (denoted as MNO ~ XYZ), then their corresponding parts are congruent. Corresponding parts include angles and sides that match between the two triangles due to their similarity in shape and proportion. In similar triangles, corresponding angles are congruent, while corresponding sides are in proportion.
The corresponding congruent angles would be angle M and angle X, angle N and angle Y, and angle O and angle Z. For the sides, the lengths are proportional, which means that the ratio of MN to XY is the same as the ratio of NO to YZ, which is also the same as the ratio of MO to XZ.
Final answer:
In similar triangles MNO and XYZ, the corresponding congruent parts are angles M, N, O congruent to angles X, Y, Z respectively and sides MN, NO, OM proportional to sides XY, YZ, ZX respectively.
Explanation:
If triangles MNO and XYZ are similar (denoted as MNO ~ XYZ), it indicates that they have the same shape but not necessarily the same size. This means that their corresponding angles are congruent, and their corresponding sides are in proportion.
The corresponding congruent parts would be:
Angle M is congruent to Angle X
Angle N is congruent to Angle Y
Angle O is congruent to Angle Z
Side MN is proportional to Side XY
Side NO is proportional to Side YZSide OM is proportional to Side ZXRemember, while the angles are congruent, the sides are proportional, which means the length of the sides of one triangle is some multiple or fraction of the lengths of the corresponding sides of the other triangle.
Luisa knit a rectangular scarf that measures 4 feet by 1 foot. She wants to use the remaining 6 square feet of fabric to create a border around the scarf.
Which equation can she use to find the required width of the border x?
To solve this problem, let us recall that the formula for Area of a rectangle is:
A = l * w
Where,
l = length of one side = 4 ft
w = width of one side = 1 ft
Therefore the original area is:
Ao = 4 ft * 1 ft
Ao = 4 ft^2
Since each border would be increased by x, therefore the new l and w would be:
l = 4 + 2x
w = 1 + 2x
The new area becomes:
A = (4 + 2x) (1 + 2x)
The difference of the two would be the area of the remaining scarf:
A – Ao = 6 square ft
(4 + 2x) (1 + 2x) – 4 = 6 ---> 1
(4 + 2x) (1 + 2x) = 10 ---> 2
The equation to use can be equation 1 or equation 2.

A mother gives birth to a 9 pound baby. every 4 months, the baby gained 2 pounds. if x is the age of the baby in months, then y is the weight of the baby in pounds. find an equation of a line in the form y = mx + b that describes the baby's weight.
Final answer:
The equation of the line that represents the baby's weight as it grows is y = 0.5x + 9, where x is the age of the baby in months, and y is the weight of the baby in pounds.
Explanation:
The student is looking for an equation of a line that represents the weight of a baby as it grows. This situation can be described using a linear equation in the form of y = mx + b, where y represents the weight of the baby in pounds, x represents the age of the baby in months, m is the rate at which the baby gains weight, and b is the initial weight of the baby at birth.
Given that the baby weighs 9 pounds at birth, we have our b value as 9. It is also given that the baby gains 2 pounds every 4 months, which can be converted to a monthly weight gain of ½ pound per month (since 2 pounds ÷ 4 months = ½ pound per month). Consequently, the value of m is ½ or 0.5.
Using these values, the equation of the line that describes the baby's weight over time can be written as:
y = 0.5x + 9
This equation indicates that the baby's weight (y) is 9 pounds at birth (when x = 0) and increases by 0.5 pounds each month.

A sphere fits snugly inside a 6-in. cube as shown. what is the volume of the region inside the cube but outside the sphere
The volume of the region inside the cube but outside the sphere is approximately 187.73 in^3.
Explanation:The volume of the region inside the cube but outside the sphere can be calculated by subtracting the volume of the sphere from the volume of the cube.
Volume of the cube = side^3 = 6^3 = 216 in^3
Volume of the sphere = (4/3)πr^3
Since the sphere fits snugly inside the cube, the radius of the sphere is half the length of the side of the cube. So, r = 3/2 in.
Therefore, volume of the region = volume of the cube - volume of the sphere = 216 in^3 - (4/3)π(3/2)^3 in^3 = 216 in^3 - 9π in^3 = 216 in^3 - 28.27 in^3 ≈ 187.73 in^3.
what is the final step to solving the inequality -2(5-4x)<6x-4
Answer:
x< 3
Step-by-step explanation:
-2(5-4x)<6x-4
multiply -2 inside the parenthesis
-2 * 5 = -10
-2 * -4x= 8x
-2(5-4x)<6x-4
-10 + 8x < 6x -4
To solve for x we need 'x' on the left hand side
Subtract 6x from both sides
-10 + 8x -6x< 6x -6x -4
-10 +2x < -4
Add 10 on both sides
-10 +10 +2x < -4+10
2x < 6
divide by 2 on both sides
x< 3
What is the complete factorization of the polynomial below?
x3 - 3x2 + x - 3
Final answer:
The complete factorization of the polynomial x³ - 3x² + x - 3 is (x - 3)(x² + 3)(x + 1).
Explanation:
The complete factorization of the polynomial x³ - 3x² + x - 3 can be found by using the Rational Root Theorem and synthetic division. By trying out the possible rational roots using the Rational Root Theorem, we find that one of the roots is 3. So, we divide the polynomial by (x - 3) to get the quadratic factor and the remaining linear factor.
(x - 3) is a factor, so we divide x³ - 3x² + x - 3 by (x - 3) using synthetic division:
3|1-31-3|3030|1010
The result is x² + 3.
The remaining linear factor is 1x + 1 = x + 1.
Therefore, the complete factorization of the polynomial x³ - 3x² + x - 3 is (x - 3)(x² + 3)(x + 1).
Find the zeros of the function.
