two trains leave stations 560 miles apart at the same time and travel toward each other. one train travels at 95 miles per hour while the other travels at 105 miles per hour. how long will it take for the two trains to meet?
It will take 2 hours 48 minutes for the two trains to meet.
For given question,
Two trains leave stations 560 miles apart at the same time and travel toward each other.
One train travels at 95 miles per hour while the other travels at 105 miles per hour.
This means the speed one train is 95 mph while the speed of other train is 105 mph.
Let t be the time in hours for two trains to meet.
From given scenario,
⇒ 560 = (105 + 95)t
⇒ 560 = 200 t
⇒ t = 2.8 hours
1 hour = 60 minutes
So, 0.8 hours = 48 minutes
⇒ 2.8 hours = 2 hours 48 minutes
This means, both trains meet after 2 hours 48 minutes
Therefore, it will take 2 hours 48 minutes for the two trains to meet.

Mr. Zuro finds the mean height of all students in his statistics class to be inches. Just as mr. Zuro finishes explaining how to get the mean, danielle walks in late. Danielle is inches tall. What is the mean height of the students in the class?.
Mean height of the students in the class = 65.7 inches
The mean height of all 12 students in the class is 66.0 inches.
So the Total height of 12 students in the class = 66 × 12
= 792 inches
As Danielle's height = 62.1 inches
So the total height of 13 students = 792 + 62.1
= 854.1 inches
Mean of all 13 students in the class = 854.1 / 13
= 65.7 inches

Choose an expression for the input-output table. Next, using a variable for the value in the input column, determine the next two values in the table if the table were followed.
Option a, 2x + 1, 6 and 13, 7 and 15.
Here, we are given input-output table as shown in the figure.
To find the equation for this table let us look at each option one by one-
a. 2x + 1
Here if we take input x = 2
output = 2(2) + 1
= 5
If x = 3
output = 7
and if we check for other values also, 2x + 1 will satisfy.
Thus, 2x + 1 is the correct equation.
we can check the points as well-
if x = 6
output = 2(6) + 1 = 13
and if x = 7
output = 2(7) + 1
= 15
Since, we've found the correct answer in option a, we do not need to check the other options.
Thus, option a is the correct answer.

a. Find R(17) =
By substituting the value of x as 17 in the function R (x) = 2 x + 3.5, we get the value of R ( 17 ) as 37.5.
We are given a function:
R (x) = 2 x + 3.5
where x represents the number of feet the tide moves x minutes after 4 pm.
Now, we are asked to find R (17)
For this, we need to substitute the value of x as 17 that is we need to put x = 17 in the function that is given to us.
R ( x = 17 ) = 2 ( 17 ) + 3.5
R ( 17 ) = 34 + 3.5
R ( 17 ) =37.5
Therefore, by substituting the value of x as 17, we get the value of R ( 17 ) as 37.5.

51 m
h
48 m
51 m
Step-by-step explanation:
there is no "x" in the whole scenario.
you and your teacher mean "h" ?
this we get by using Pythagoras, because h, half of the baseline and one of the 51 m sides create a new right-angled triangle :
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle). a and b are the legs.
so, for that new inner triangle we have then
51² = h² + (48/2)² = h² + 24²
2601 = h² + 576
h² = 2025
h = 45 m

Equation: [tex]\sf 3x + x + 14 = 90[/tex]
m∠1 = 57°
m∠2 = 33°
Explanation:
A right angle triangle has 90° angle measure.
Here:
m∠1 + m∠2 = 90°
(a)
Substitute given values:
(3x) + (x + 14) = 90
simplify
4x = 90 - 14
evaluate
4x = 76
divide both sides by 4
x = 19
(b)
m∠1 = 3x = 3(19) = 57°
m∠2 = x + 14 = 19 + 14 = 33°
Answer:
[tex]\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]
[tex]\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}[/tex]
[tex]m \angle 2=\boxed{33}\:^{\circ}[/tex]
Step-by-step explanation:
From inspection of the given diagram:
[tex]m \angle 1=(3x)^{\circ}[/tex][tex]m \angle 2=(x+14)^{\circ}[/tex]Part (a)A right angle is 90° and is represented by the ∟ symbol.
To find x, equal the sum of the angles to 90° and solve for x:
[tex]\implies m \angle 1+m\angle2=90^{\circ}[/tex]
[tex]\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]
[tex]\implies 3x+x+14=90[/tex]
[tex]\implies 4x+14=90[/tex]
[tex]\implies 4x+14-14=90-14[/tex]
[tex]\implies 4x=76[/tex]
[tex]\implies 4x \div 4=76 \div 4[/tex]
[tex]\implies x=19[/tex]
Part (b)To find the degree measure of each angle, substitute the found value of x into the expression for each angle.
[tex]\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}[/tex]
[tex]\implies m \angle 2=(19+14)^{\circ}=33^{\circ}[/tex]

Large numbers are those numbers that have a bigger value than the numbers that we use in daily life. such numbers tend to create a sense of fear among children and they often skip solving problems that have large numbers in them. for example, 1 million, 1 billion, etc., are large numbers that are used either to show the population of a country or express large amounts of money in a bank account.
These periods are named as ones, thousands, lakhs, and so on. The one's period consists of the first three digits of the large number, starting from the right.
Everyone learns how to count numbers at a very young age starting from a single digit up to seven digits. This is done with the help of the place value system.
While writing large numbers, we always keep the place value system in mind to ensure that it is written correctly. According to the Indian place-value system, when a number is written in the standard form, each group of digits separated by a comma is called a period.
These periods are named as ones, thousands, lakhs, and so on. The one's period consists of the first three digits of the large number, starting from the right. The thousands period consists of the next two digits. The lakhs period consists of the next two digits and it continues.
Some other large numbers are read and written as follows:
1,000,000,000 = one billion
1,000,000,000,000 = one thousand billion
