I will help you on two conditions:  1) that you never again call yourself "stupid," and that you ask no more than 1 or 2 questions per post.

I'll focus on #5.  Recall that distance = rate times time:  d = r*t.

You want distance and are given rate and time:  rate 1.8 km/min; time 48 min.

I see you write "distance" next to "1.8 km;" that is not correct, because

the problem states that "the rate is 1.8 km per minute."  1.8 km is a distance; 1.8 km / min is not (it's a rate).

So, again, to find the distance traveled, mult. the rate by the elapsed time:
 
distance = (1.8 km/min)(48 min) = 86.4 km, or about 54 miles.

<h3>Answer: Choice C) $1,444.50</h3>

========================================================

There are two methods to get the answer.

The slightly longer method is to take 7% of the original price to get

7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50

The sales tax is $94.50

Add this onto the original price to get 1,350+94.50 = 1,444.50

----------------------------

A shortcut is to multiply the original price by 1.07

The multiplier 1.07 represents a 7% increase since

  • 1 = 100%
  • 0.07 = 7%
  • 1.07 = 1 + 0.7 = 100% + 7%

So we will have 1.07*1350 = 1,444.50

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$45 thousand less than twice that of an
Lera25 [3.4K]

Answer:

<h2>$58500</h2>

Step-by-step explanation:

 let the degree holder earn  x

 then a masters degree holder earns= (2x-45,000)

the comnined amount of the two degree holders=   (2x-45,000)+x

2x-45000+x=117000

3x=117000+45000

3x=162000

x=162000/3

x=$54000

so bachelor'sdegree hold earns= $54000

a masters degree holder earns= (2(54000)-45,000)

a masters degree holder earns= (108000-45,000)

a masters degree holder earns=$63000

the average= (54000+63000)/2

the average= (117000)/2

the average=$58500
