Answer:
Time passes until the second bus catches up with the first bus = 2 hours
Step-by-step explanation:
One bus leaves the terminal at 4:00 p.m. and travels at 40 miles per hour.
Speed of Bus 1 = 40 miles per hour
Time of leaving of Bus 1 = 4:00 p.m
The second bus leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
Speed of Bus 2= 60 miles per hour
Time of leaving of Bus 2 = 5:00 p.m
We need to find when they catch up
That is the distance traveled by them are same,
Let the time of travel for bus 1 be t, so time of travel for bus 2 is t -1
We have
Distance = time x Speed
Distance traveled buy bus 1 = Distance traveled buy bus 2
40 x t = 60 x (t -1 )
40 t = 60 t - 60
20t = 60
t = 3 hours,
So after 3 hours of starting of bus 1 they catch up,
Time passes until the second bus catches up with the first bus = t- 1 = 2 hours
Time passes until the second bus catches up with the first bus = 2 hours
The second bus takes 2 hours to catch up with the first bus after closing a gap of 40 miles at a relative speed of 20 miles per hour.
Calculating the Time for the Second Bus to Catch Up
To determine how much time passes until the second bus catches up with the first bus, we need to calculate the distance that the first bus travels before the second starts and then use the relative speeds of the buses to find out when the second bus will have covered the same distance.
The first bus travels for one hour before the second starts, covering a distance of:
Distance = speed x time = 40 miles/hour x 1 hour = 40 miles.
When the second bus starts, it closes the gap at a relative speed, which is the difference in their speeds:
Relative speed = 60 miles/hour - 40 miles/hour = 20 miles/hour.
To find out how long the second bus takes to catch up, we use the formula:
Time = Distance / Relative speed = 40 miles / 20 miles/hour = 2 hours.
So, it will take the second bus 2 hours to catch up with the first bus.
An investment of $750 earns 3.3% Interest compounded monthly. What is the equation that modelsThe value of investment
Final answer:
To find the value of an investment with monthly compound interest, you use the formula [tex]A = P(1 + r/n)^{nt}[/tex]. For a $750 investment at a 3.3% interest rate compounded monthly, the equation is [tex]A = $750(1 + 0.033/12)^{12t}[/tex]. The formula accounts for principal, interest rate, compounding frequency, and number of years.
Explanation:
To model the value of the investment with compound interest, we use the compound interest formula:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Where,
So for an investment of $750 at a 3.3% interest rate compounded monthly, the equation would be:
[tex]A = 750(1 + \frac{0.033}{12})^{12t}[/tex]
This equation can be used to calculate the value of the investment after t years. Monthly compounding means that the interest is calculated and added to the account balance 12 times a year.
There are 318 fiction books in the class library.the number of nonfiction books is 47 less than the number of fiction books about how many nonfiction books are there in the class library?explain
Answer:
271 books
Step-by-step explanation:
Given: There are 318 fiction books in the class library.the number of nonfiction books is 47 less than the number of fiction books.
To find: About how many nonfiction books are there in the class library
Solution: It is given that 318 fiction books in the class library.
Also it is given that the number of nonfiction books is 47 less than the number of fiction books.
Let us assume that there are x nonfiction books,
So, we have
[tex]x=318-47[/tex]
[tex]x=271[/tex]
Hence, the number of nonfiction books is 271.

The preventative maintenance plan for your automobile is $896. If you were required to replace your water pump and starter for $316 and $443, respectively, how much did the repairs cost you?
A. $896 (Would the maintenance plan cover it so it would just be 896?)
B. $316
C. $661
D. $1,655
Answer:
Option A is correct because the maintenance plan covers the cost of repair.
Step-by-step explanation:
We are supposed to replace water pump and starter for $316 and $443, respectively.
So, total cost = [tex]316+443[/tex]
= $759
Since we are given that the preventative maintenance plan for your automobile is $896.
The total cost of repair is under the maintenance plan .
So, the answer is $896.
Option A is correct because the maintenance plan covers the cost of repair.

the coffee pub has cans of coffee that weight 3 1/4 pounds each. the pub has 8 1/2 cans of coffee left. What is the total weight of 8 1/2
To find the total weight of 8 1/2 cans of coffee, multiply the weight of each can by the number of cans. The total weight is 27 1/2 pounds.
The total weight of 8 1/2 cans of coffee can be found by multiplying the weight of each can (3 1/4 pounds) by the number of cans left (8 1/2).
3 1/4 pounds x 8 1/2 = 27 1/2 pounds
Therefore, the total weight of 8 1/2 cans of coffee is 27 1/2 pounds.
Anthony is making a collage for his art class by picking shapes randomly. He has five squares, two triangles, two ovals, and four circles. Find P(a square is not chosen first).
PLEASE HELP!
15 POINTS
Answer:
C) P = [tex]\frac{8}{13}[/tex]
Step-by-step explanation:
Square: 5
Triangle: 2
Ovals: 2
Circles: 4
Using formula of probability:
Probability = [tex]\frac{Favourable Outcomes}{Total Outcomes}[/tex] ----- 1
Total Outcomes: 5 + 2 + 2 + 4 = 13
Favourable Outcomes: 2 + 2 + 4 = 8 (Excluding 5 squares)
A sqaure is not chosen first, which means that any shape of the rest of 8 shapes can be chosen
so eq 1 becomes
P = [tex]\frac{8}{13}[/tex]
solve for y, then find the value of y when given x = -2. 6x = 7 - 4y
To solve for y in the equation 6x = 7 - 4y, isolate the y-term by subtracting 7 and dividing by -4. When x = -2, y = 15/4.
Explanation:To solve for y in the equation 6x = 7 - 4y, we can start by isolating the y-term. First, subtract 7 from both sides of the equation to get 6x - 7 = -4y. Then, divide both sides by -4 to isolate y and change the sign, giving us y = -6x/4 + 7/4. To find the value of y when x = -2, we substitute -2 into the equation:
y = -6(-2)/4 + 7/4 = 3 + 7/4 = 3 3/4 = 15/4

which is bigger 3/8 or 0.38
0.38 is bigger than 3/8.
Explanation:To compare 3/8 and 0.38, we need to convert them to the same form. Since 0.38 is already in decimal form, we need to convert 3/8 to decimal form as well. Dividing 3 by 8 gives us 0.375.
Comparing 0.375 and 0.38, we can see that 0.38 is bigger than 0.375. So, 0.38 is bigger than 3/8.
