Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but let me solve a similar question:
Three trains one eastbound, one westbound, and one northbound leave a city at the same time. The speed of the northbound train is 20 miles per hour greater than the speed of the eastbound train. After 6 hours, the distance between the westbound train and the eastbound train is 420 miles. Twice the speed of the westbound train is 30 miles per hour more than the speed of the northbound train. Find the speeds of the three trains.
Solution:
Speed is the time rate of change of distance. It is the ratio of distance to time taken. Speed is given by:
Speed = distance / time
Let x represent the speed of the eastbound train, y that of the westbound train and z that of the northbound train. Hence:
z = x + 20
x - z = -20 (1)
After 6 hours, the distance between the westbound train and the eastbound train is 420 miles. Hence:
6 hours * x + (6 hours * y) = 420
6x + 6y = 420
x + y = 70 (2)
Lastly:
2y = z + 30
2y - z = 30 (3)
Solving equations (1), (2) and (3) simultaneously gives:
x = 30 miles per hour, y = 40 miles per hour, z = 50 miles per hour.
Hence the speed of the eastbound train is 30 miles per hour, speed of the westbound train is 40 miles per hour and the speed of the northbound train is 50 miles per hour.

Ted earned $4,300 from his summer internship that he plans to invest so that he can buy a used car after three years. Ted chooses a bank that offers 5.5% compounded quarterly. Can Ted buy a car that costs $4,700 after three years? Round your numbers to the nearest cent.
Answer: Yes he will be
Step-by-step explanation:
To find out if Ted can afford the car, find the future value of $4,300 in three years.
First convert the number of years and rates to quarterly values as this is the compounding period:
Term = 3 * 4 quarters = 12 quarters
Rate = 5.5% / 4 = 1.375% per quarter
Future value = Amount * ( 1 + rate) ^ term
= 4,300 * ( 1 + 1.375%)¹²
= $5,065.69
Considering that Ted makes $5,065.69 in 3 years, he will be able to buy a car that costs $4,700.
Michelle’s house is 22 miles due north of Jan’s house and 30 degrees northeast of Richard’s house. Richard’s house is due east of Jan’s house. How far is it from Michelle’s house to Richard’s house?
Answer:
Michelle’s house is 44 miles to Richard’s house.
Step-by-step explanation:
The distance can be found out by using the trigonometric ratio of sine theta
Sine theta= Perpendicular/ Hypotenuse
We know the values of hypotenuse and theta
Sine 30 = 22/ Hypotenuse
Hypotenuse= 22/ sine 30
Hypotenuse= 22/0.5
Hypotenuse = 44
The hypotenuse marks the distance between Michelle’s house to Richard’s house. Due east means counter clockwise rotation from east.

Answer:
The answer is 276.32 square yards.
Step-by-step explanation:
To solve for the surface area of a cylinder, use the surface area of a cylinder formula, which is SA= 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]. However, instead of using ([tex]\pi[/tex]), 3.14 will be used.
Next, plug in the information from the question into the formula. The formula will look like SA= 2(3.14)(4)(7) + 2(3.14)([tex]4^{2}[/tex]). Then, solve the equation, and the final answer will be 276.32 square yards.
