Two trains have to travel a distance of 300 miles. Train A goes at the speed of 50 mph and Train B goes at the speed of 60 mph. However, Train B leaves 1 hour later than Train A. When will the 2 trains meet?
Answer:
Both trains would meet in 6 hours time.
Step-by-step explanation:
Train A = 50 miles per hour
Train B = 60 miles per hour
Train B leaves 1 hour later than Train A: This means Train A started the journey first.
When will the 2 trains meet?
Both trains would meet when they both cover equal distance.
Distance = Speed * Time
First Hour
Train A = 50 miles
Train B = 0 miles
Second Hour
Train A = 100 miles
Train B = 60 miles
Third Hour
Train A = 150 miles
Train B = 120 miles
Fourth Hour
Train A = 200 miles
Train B = 180 miles
Fifth Hour
Train A = 250 miles
Train B = 240 miles
Sixth Hour
Train A = 300 miles
Train B = 300 miles
Both trains would meet in 6 hours time.
Mrs. Piazza invested $8000 in a certificate of deposit that pays 3% simple interest for 4 years. How much will be in Mrs. Piazza's account at the end of 4 years?
Answer:
$8960
Step-by-step explanation:
Given
principal = $8000
rate= 3%= 0.03
time = 4 years
Required
the final amount, we assume that this is a simple interest investment.
Step two:
[tex]A= P(1+rt)\\\\A=8000(1+0.03*4)\\\\A=8000(1+0.12)\\\\A=8000*(1.12)\\\\A=8960[/tex]
The final amount in the account is $8960
use the function y=3/2x+3 to complete the table of values
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
Putting all the values of y=9, 6, 0, and -3 to complete the table
FOR y=9
putting y=9
switch sides
subtract 3 from both sides
Hence,
when y=9, x=4
FOR y=6
putting y=6
switch sides
subtract 3 from both sides
Hence,
when y=6, x=2
FOR y=0
putting y=0
switch sides
subtract 3 from both sides
Hence,
when y=0, x=-2
FOR y=-3
putting y=-3
switch sides
subtract 3 from both sides
Hence,
when y=-3, x=-4
Hence, the table becomes:
x y
9 4
6 2
0 -2
-3 -4

Answer:
So, lets say the refridgerator started at 37 degrees F alright?
Step-by-step explanation:
37 - 4 = 33
33 + 2 = 35
35 - 7 = 28
28 - 1 = 27
27 + 3 = 30
30 + 1 = 31
So the final temurature at 2:00pm would be 31 degrees F
Hope this helped :)
2x^2-11x + 5.o-x^2 + 4x +371 =0
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

Slope of line a is ½. What is the equation of a line that is parallel to line a? Y+½x=2 -2x+y+2=0 2x-2=y -½x+y-2=0
Answer:
The equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Step-by-step explanation:
A line is a polynomial function of the first degree that has the following form:
y = m * x + b
where m is the slope of the line and b is the intercept with the Y axis. The slope is the inclination of the line with respect to the abscissa axis.
In this case you know that the slope of line a is ½.
Parallel lines are two or more lines in a plane that never intersect. Two lines are parallel if they have the same slope and different y-intercepts.
You have:
y+½x=2 → y= -½x +2-2x+y+2=0 → y=2x -22x-2=y -½x+y-2=0 → y=½x + 2The line that has the same slope as line a is the last one, so the equation of a line that is parallel to line a is y=½x + 2, or what is the same -½x+y-2=0
Susan got 72 marks in English out of 120 and 70 marks in
Hindi out of 150. The maximum marks in the mathematics
paper were 180. If she got 60% marks in all the three papers
how y marks did she get in mathematics?
Answer:
let the marks obtained in maths be x
total marks obtained by susan=142+x
then
A/Q
60%of 450 =(142+x)
270=142+x
x=270-142
x=128
hence marks obtained in maths=128
OR
Max marks 120+150+180=450
60% of 450 is 270
70 +72+x=270
x=270-142
x=128

Which equation represents a line which is perpendicular to the line y = 4/3x-6
Given (x+1)2=9, solve for x
Answer:
x= 7/2
2(x+1)=9
x+1=9/2
x=9/2 - 1
x=7/2
Answer:
x=7/2 x=3.5
Step-by-step explanation:
divide both sides by 2
(x+1)(2)/2=9/2
simplify
x+1=9/2
subtract 1 from both sides
x+1-1=9/2-1
simplify
x=7/2
u = 4i + 9j
8= -8j
Find: u +g
Answer:
4i + j
Step-by-step explanation:
I think you meant g instead of 8.
Given:
u = 4i + 9j
g = -8j
u + g
(4i + 9j) + (-8j)
4i + j

Sierra's ice cream shop made $45 before she had to close early when the power went out. She realized she lost Two-thirds of a dollar each hour when the shop was closed. The expression that models this situation is 45 minus two-thirds h. What was Sierra's profit if the shop was closed for 6 hours? $24 $36 $41 $49
Answer:
the profit in the case when the shop is closed for 6 hours is $41
Step-by-step explanation:
The computation of the profit in the case when the shop is closed for 6 hours is shown below:
= Expression of the situation × number of hours in which the shop is closed
= 45 - 2 ÷ 3 × 6 hours
= $41
hence, the profit in the case when the shop is closed for 6 hours is $41
Therefore the third option is correct

tan22° + tan23° tan22°. tan23° = 1 prove that
Answer:
Formula:(from trigonometry)
Tan(A+B)=(tanA+tanB)/(1-tanA*tanB)
Let A=22 degrees,B=23 degrees
Tan(22+23)=(tan22+tan23)/(1-tan22*tan23)
From trigonometry we know tan45=1
Therefore tan(45)=1=(tan22+tan23)/(1-tan22tan23)
=> 1-tan22tan23=tan22+tan23
=> tan22+tan23+tan23tan22 =1
Hence proved

Assume you know that a hot-air balloon is currently inflated with a certain amount of air and that the amount is a percent of the total amount required to inflate the balloon. Explain how you would determine the total amount of air required to inflate the balloon.
Answer:
Percent air is calculated as:
Percent air = Current amount/Total amount *100Solve for total amount of air:
Total amount = Current amount / Percent air * 100Substitute the values in hand to get the answer
