A train left a station at 8:00 am going at 45 mph. A second train left the station at 10:00 am going in the same direction at 55 mph. At what time will the second train catch up with the first train?
Answer: At 5:00 pm the second train catch up with the first train.
Step-by-step explanation:
Let t = Time taken by first train.
Time taken by second train = t-2
Speed of train 1 = 45 mph
Speed of train 2 = 55 mph
Since, Distance = speed x time
Then, [tex]45t= 55(t-2)[/tex]
[tex]\Rightarrow\ 45t= 55t-110[/tex]
[tex]\Rightarrow\ 55t-45t=110= \\\\\Rightarrow\ 10t=110\\\\\Rightarrow\ t=11[/tex]
After 11 hours, time = 8+11 =17(12+5)i.e. 5 : 00 pm.
Hence, At 5:00 pm the second train catch up with the first train.
A line is given by the equation y=− 1 3 x+2 Find the coordinates of x-intercept of the line.
Answer:
Step-by-step explanation:
First you find the coordinates. Once you have your starting point, you use the slope in the equation to start graphing the line. Since the numerator is negative, the line is going down. The denominator is a 1 so it will be going 1 unit to the right. The x intercept would be the first point of contact on the x axis, which would be (1,0)
Answer:
x intercept = 6, 0
y intercept = 0, 2

pls help me :( i dont remember these
Answer:
x = 16
Step-by-step explanation:
1/2(x-4) = 1/3(x+2)
Multiplying through by the LCM,6 to take off the denominators;
6 × 1/2(x-4) = 6 × 1/3(x+2)
Simplifying;
3(x-4) = 2(x+2)
3x -12 = 2x + 4
Grouping like terms;
3x - 2x = 4 + 12
x = 16

The Empire State Building is 1250 feet tall . Maria wants to make a model that has a scale of 1/4 foot = 50 feet . How tall will her model be ?
Answer:
6 1/4 feet or 6.25 feet
Step-by-step explanation:
First,, we would do 1250/50 to get 25. This is the amount that we would multiply 1/4 by, so we can get 6.25. So her model will be 6 feet and 1/4 of a foot. :)

Answer:
z = 20(cosπ/6 + isinπ/6)
Step-by-step explanation:
Given the complex value
z1 = -10√3 - 10i
The polar form of the complex number is expressed as;
z = r(costheta + isintheta)
r is the modulus of the complex number
theta is the argument
r = |z1| = √x²+y²
r = √(-10√3)²+(-10)²
r = √(100(3)+100
r = √400
r = 20
theta = tan^-1(y/x)
theta = tan^-1(-10/-10√3)
theta = tan^-1(1/√3)
theta = 30°
Substitute into the polar form
z = 20(cos 30°+isin30°)
z = 20(cosπ/6 + isinπ/6)

Stan is buying party favors for his birthday party. There will be 20 guests at his party. Party favors come in packages of 6. What is the least number of packages he needs to buy so that all his guests get a party favor?
Answer:
The minimum package Stan need to buy so that all his guests get a party favor is 4 packages.
Step-by-step explanation:
Given;
total number of guest in the party = 20
number of party favor needed = 20 party favors
1 package = 6 party favor
then, 2 package = 12 party favor
3 package = 18 party favor
4 package = 24 party favor
24 party favor will serve all the guest.
Therefore, the minimum package Stan need to buy so that all his guests get a party favor is 4 packages.

An office building contains 6,500 square feet of space. Each employee has a cubicle that takes up 100 square feet. The entryway takes up 400 square feet. Which inequality can be used to find the possible number of cubicles?
a
F 100x + 400 ≤ 6,500
b
G 100x + 400 ≥ 6,500
c
H 100x – 400 ≤ 6,500
d
J 400x – 400 ≤ 6,500
Answer:
100a + 400 ≤ 6500
Step-by-step explanation:
The office building contains 6500 ft² of space. Each employee has a cubicle that takes up to 100 ft². The entryway also takes up to 400 ft². The inequality that can be use to find the possible number of cubicles is expressed below.
Let
number of employee/cubicle = a
Total space of the office building = 6500 ft²
The entryway has already occupied 400 ft² of the office building space. Each employee has one cubicle which takes up to 100 ft² of the office building space. The space occupied by the cubicle in the office building can be calculated when you multiply the number of cubicle/employee by 100(size of each cubicle) This will be 100 × a = 100a. The total number of space occupied by the cubicles plus the already space taken by the entryway will be less than or equal to the total space of the office building. Therefore,
100a + 400 ≤ 6500
Answer:
100a + 400 ≤ 6500
Step-by-step explanation:
The space occupied by the cubicle in the office building can be calculated when you multiply the number of cubicle/employee by 100(size of each cubicle)

Last week, Angelo deposited a $800 check from his restaurant job and spent $500 on a clarinet. Which integer represents the change in how much money Angelo had?
Answer:
The change in how much money that Angelo had is $300.
Step-by-step explanation:
Since Angelo deposited a $800 check, which implies that he would have $800 at maturity of the check.
He spent $500 on a clarinet from the $800.
So that,
The change in how much money Angelo had = amount deposited - amount spent on the clarinet
= $800 - $500
= $300
Therefore, the change in how much money that Angelo had is $300.

A baker has 3 4 pound of sugar left in his pantry. He needs 1 8 of a pound for each batch of cookies he makes. What is the greatest number of batches of cookies the baker can make with the 3 4 pound of sugar
Answer: 6
Step-by-step explanation:
Given: Amount of sugar he has = [tex]\dfrac34[/tex] pounds
Amount of sugar is required for each batch = [tex]\dfrac18[/tex] pounds
Now, the greatest number of batches of cookies the baker can make with the [tex]\dfrac34[/tex] pounds of sugar = [tex]\dfrac{\dfrac{3}{4}}{\dfrac{1}{8}}=\dfrac{3}{4}\times\dfrac{8}{1}[/tex]
[tex]=3\times2=6[/tex]
