3.A train can travel 360 miles in 4 hours. How much time will it take
travelling 585 miles?​

Answers

Answer 1
Answer:

Answer:

6.5 hours

Step-by-step explanation:

We can write a ratio to solve

360 miles      585 miles

---------------- = ------------

4 hours         x hours

Using cross products

360 * x = 4* 585

360 x = 2340

Divide each side by 360

x = 2340/360

x =6.5

Answers

First you should Simplify
(20)/(24) = (5)/(6)
(3)/(6) + (1)/(3) = (5)/(6)


Solution
1. Find the LCM between 6 and 3 which is 8
2. Times 3 and 6 to both sides of the equation respectively.
(3 * 3)/(18) + (6 * 1)/(18)
(9 + 6)/(18) = (15)/(18)
3. Simplify the answer by dividing by 3.

Answer:

-0.34772

Step-by-step explanation:

One way of doing this problem is to change the base from 5 to 10.

Use the change of base formula:

                 log x

log     x = ------------

     5          log 5

so:

                       log (4/7)        log 4 - log 7

log     (4/7)  = --------------- = ---------------------

     5                   log 5               log 5

Note that "log x" above is the common logarithm of x and is to the base 10.

Continuing, we get:

0.60206 - 0.84510         -0.24304

---------------------------- = --------------------- = -0.34772       (This corresponds to

        0.69897                    0.69897                              the second given

Steven wants to make some extra money using a CD account. He wants $22,000 in his account after 5 yearscompounded continuously. How much principal will he have to start with, at an interest rate of 6.625%?

Answers

Answer: You got to multiply 22,000 times 5 and that will equal 110,000

Step-by-step explanation:

Final answer:

To have a final balance of $22,000 in a CD account after 5 years with continuous compounding at an interest rate of 6.625%, Steven needs to initially deposit approximately $15,895.68.

Explanation:

To calculate how much principal Steven should start with in his CD account, we need to use the formula for continuous compounding, which is A = Pe^(rt), where:

  • A is the amount of money accumulated after n years, including interest.
  • P is the principal amount (the initial amount of money).
  • e is the base of the natural logarithm, approximately equal to 2.71828.
  • r is the annual interest rate (decimal).
  • t is the time the money is invested for in years.

In Steven's case, he wants A = $22,000 after t = 5 years, at an interest rate r of 6.625% or 0.06625 in decimal format. Substituting these values into our formula and solving for P, we get:

P = A / e^(rt)

P = 22000 / e^(0.06625 * 5)

After calculating this expression, we find that Steven needs to deposit approximately $15,895.68 into his CD account to have $22,000 after 5 years with continuousinterest compounding at 6.625%.

There are 250 students in the senior class at Stats High School. Some are involved in clubs and some have part-time jobs. 130 students have a part-time job (some of these students may be in a club). 110 students are involved in a club (some of these students may have a job). 100 students are NOT involved in a club and do NOT have a part-time job1. Draw a Venn diagram to illustrate the data.

Answers

Answer: ( i had a problem with this question too and i looked it up for a tutorial and i saw that some guy replied random things for points, so after i found the explanation, i came back here to give you a proper answer.)

Write 100  outside the circles to represent the students who do not have a job and are not in a club.

There are a total of 250 students, and 100 of them are not in the circles. So the remaining 150 must be included in the job and club circles.

The total number in the job subset is 130, and the total number in the club subset is 110. Together, this is 240 students, but there is only room for 150.

This means that 90 of the students are included in the intersection (both job and club).

The total number of students with jobs is 130, but 90 are already included in the intersection. Therefore, the difference of 40 students only have jobs.

The total number of students in a club is 110, but 90 have both jobs and attend a club. So the remaining 20 students must only attend a club.

An electronics store has a current inventory of 50 stereo systems. The lowest priced stereo system in the store sells for $800, The lowest priced stereo system in the store sells for 800 dollars, and the highest priced stereo system sells for $3000. and the highest priced stereo system sells for 3000 dollars. Which of the following is the maximum amount of $3000 systems on hand Which of the following is the maximum amount of 3000 dollar systems on hand if the current inventory totals $111,000?The answer is 32, I need an explanation how to find the answer.

Answers

B) 32

Explanation:

let H = number of expensive high price stereo

systems

let L = number of less expensive low price

stereo systems

H +L = 50 =

3,000H + 80OL = 110,000

H = 50 - L (now replace)

3,000 (50 - L) + 800 L = 110,00

150,000 - 3,000L + 800L = 110,000

150,000 - 110,000 = 3,000L - 800L =

40,000 = 2,2OOL

L = 40,000 / 2,200 = 18.18 = 18 lower priced = =

stereo systems H = 50 - 18 = 32 higher priced stereo systems

=

=

(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400

Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off
