Tourists were on a hiking trip for three days. On the first day, they hiked 1/8 of the trail. On the second day they hiked 4/7 of the remaining trail. On the third day they hiked 1/3 of the remaining trail and the last 8 km. How many km is the whole trail?

Answers

Let x = the length (km) of the whole trail.

1st day:
(1/8)x = 0.125x traveled.
Remaining amount = (1 - 0.125)x = 0.875x

2nd day:
(4/7) of 0.875x = 0.5x traveled.
Remaining amount = (1 - 0.5)x = 0.5x

3rd day:
(1/3) of 0.5x = 0.1667x traveled + 8 km

The total fractional parts traveled is
0.125x + 0.5x + 0.1667x = 0.7917x

The remaining fractional shares is (1 - 0.7917)x = 0.2083x.
This is equal to the 8 km traveled, therefore
0.2083x = 8
x = 8/0.2083 = 38.406 km

Answer: 38.4 km (nearest tenth)

2.)
3.)

Answers

Answer:

Step-by-step explanation:

Key to this method is remembering that

So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.

6/2 = 3, so add

So, c=9

Similarly, for the other two,

You don't really have to worry about the sign, since squaring will always make it positive

Use the future value formula to find the indicated value. n=27​; i=0.04​; PMT=$109​; FV=?

FV=

Answers

Answer:

The future value = $1780

Step-by-step explanation:

* Lets explain the formula of the future value

- Future Value of an annuity is used to determine the future value of a

 stream of equal payments.

- The future value of an annuity formula can also be used to determine

  the number of payments, the interest rate, and the amount of the

  recurring payments

- The future value formula is

 where:

# FV = Future Value of the annuity

# PMT= Payment amount  

# i = Annual interest rate  

# n = Number of payments

* Lets solve the problem

- n = 27

- i = 0.04

- PMT = $109

- To find FV lets use the formula above

∵ n = 27 , i = 0.04 , PMT = 109

∴ FV = 1779.92 ≅ 1780

∴ The future value = $1780

Answers

Answer:

Step-by-step explanation:

Look at the given points C and D on the graph :

A coordinate plane graph is shown. Point C is at (-5,-1) Point D is at (0,3). A segment connects the two points.

What is the distance (in units) between points C (-5,-1) and D (0,3) ? Round your answer to the nearest hundredth.

Group of answer choices

a) 5.50 units

b) 6.40 units

c) 9.00 units

d) 41.00 units

TO FIND :

The distance (in units) between points C  (-5,-1) and D (0,3)

SOLUTION :

Given that  a coordinate plane graph is shown.

Point C is at (-5,-1) Point D is at (0,3).

A segment connects the two points.

Let the points C (-5,-1) and D (0,3) be  and  

The distance formula for the given two points is given by :

units

Substitute the points in the distance formula we get,

units

= 6.4031

s = 6.40 units

Option b) 6.40 is correct

The distance between the given points C and D is 6.40 units.
