If a train traveled at 50 meters within 120 seconds, what is its speed?

Alja [10]

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

$v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s$

So, the speed of a train is 0.416 m/s.

Use the present value formula to determine the amount to be invested now, or the present value needed.

Vladimir79 [104]

Answer:

The value needed now is $102,296.60

Step-by-step explanation:

Here, we want to calculate the present value needed.

We shall be using the formula for compound interest here

Mathematically;

A = I(1 + r/n)^nt

According to the question;

I is the initial amount which is what we want to calculate

A is the accumulated amount with interest = 140,000

r is the interest rate = 8% = 8/100 = 0.08

n is the number of times interest is compounded which is 4, since it is quarterly

t is the number of years = 2

Substituting these values, we have ;

140,000 = I(1 + 0.08/2)^(4 * 2)

140,000 = I(1.04)^8

I = 140,000/(1.04)^8

I = 102,296.62870027774

Which is I = $102,296.60 to the nearest cent

A town in east Texas received 15 inches of rain in two weeks. If it kept raining at this rate for a 31−day month, how much rain

blsea [12.9K]

Answer:

33 inches

Step-by-step explanation:

The problem above shows a "direct proportion," which means that when one quantity increases (days), the other quantity increases (inches of rain).

Step 1: Represent the amount of rain by n.

Step 2: Setup a proportion.

$\frac{15}{14}$ = $\frac{n}{31}$ (where 14 refers to the number of days in 2 weeks)

Step 3: Cross multiply:

15 x 31 = 14n

465 = 14n

Step 4: Find n by dividing both sides by 14.

n = 33.21

Step 5: Round off to the nearest inch.

n = 33 inches

The backers at Healthy Bakery can make 320 bagels in 10 hours. How many bagels can they make in 18 hours? What was the rate per

Vesnalui [34]

320 divided by 10 is equal to 32. So, the bakers can make 32 bagels per hour. Then, you do 32 times 18 which is equal to 576 bagels in 18 hours.
