er that proportion applied to the hotel where she worked, so she took a random sample of 700700700 of the approximately 10{,}00010,00010, comma, 000 visitors to the hotel one month and checked whether they used their room alarm clock. Of the sampled visitors, only 35\55, percent used the alarm clock.

A table costs $350. There is also a sales tax of 7%. How much does the table cost, including sales tax?
IrinaVladis [17]
Tax
$350x0.07
=$24.50

(0.07 is the 7% tax in decimal form)

Total cost
$350+$24.50
=$374.50

OR

$350x107%
=$374.50

1.07 is the table cost (100%) plus the sales tax (7%)

The table costs $374.50 with tax.

450 is shared between two workers John and Andrew if John gets 50 more than Andrew how much does John get​
NemiM [27]

450 divided by 2 is 225. 225-50=175. 225+50=275

John has 275 and Andrew has 175.

In order to get this answer, first you divide the whole number by 2. Then you get the number 225. You then have to subtract 50 from 225 because John gets 50 more than Andrew. Then for John, you have to add 50 to 225. To self-check the answer, here is the formula: 175+275=450. Remember that on these kind of word problems, you first divide the whole. Then subtract and add the number that one person gets more than the other person.

X+5(x-1)=(x-3)4-1 anyone?
Troyanec [42]
Hi there!

First of all simplify x+5(x-1)=(x-3)4-1.
This would make 6x-5=4x-13.

Next, subtract 4x from both sides.
6x-5-4x=4x-13-4x
2x-5=-13

Then add 5 to both sides.
2x-5+5=-13+5
2x=-8

Finally divide by 2 on both sides.
2x/2=-8/2
x=-4

Your answer is -4.

Hope this helped!

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile
wolverine [178]

Answer:

The value is  v =  49.23 \  mph

Step-by-step explanation:

From the question we are told that

  The  distance from Jacksonville to Miami is  d  =  382 miles

  The  time it take to travel from Jacksonville to Daytona is  t_1  = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} =  1.9 \  hours

  The  time it take to travel from Daytona Beach to Fort Pierce is t_2  = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} =  2.85 \  hours

    The  time it take to travel from Fort Pierce to West Palm Beach is  

t_3  = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} =  1.38 \  hours

     The  time it take to travel from West Palm Beach to Miami t_4  = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} =  1.63 \  hours

Generally the average speed is mathematically represented as

      v  =  \frac{d}{t_1 + t_2 +t_3 + t_4 }

=>   v  =  \frac{382}{1.9  + 2.85 +1.38 + 1.63 }

=>    v =  49.23 \  mph
