39.42 divided by 5.4

Answers

39.42 divided by 5.4 is 7.3

Heres an example without a decimal.

$5√(300)$ i kknow i know, your going to say.. but but, theres a little line there!! but ignore that little line. so, $5√(300)$ you have to try to find the highest number possible to equal that number. so 5 into 3 goes into 0 times.. so we can't use 3... okay.. what about 5 into 30?? well, yes!!! so, you put the 6 at the top, and you put 30 under the 300, but keep in mind, DO NOT FOCUS ON THE NUMBER THAT IS NOT USED. so, also, put the number "6" on the part that equals or something so that would be on the 0, next to the three.

6
    $5√(300)$
-30
-----
0
OKay, now your done it that, you got one more number!! which is 0. I know you can't do 0 divided by 5 so just put a "0" on top of zero next to 6 then you subtract as show below: also i forgot!!! birng down the 0 so it would be like this:

60
   $5√(300)$
-30
------
00 (can't do the arrow thing so yeah sorry about that)
but now you got the 00, so thats where you subtract that and get zero like this,
   60
$5√(300)$
-30
------
00
-0
-----
0
so the number is, and the number has no more numbers left, so 60 will be our answer. Sorry if it was a bit complicated.. but yeah... Hope i helped!!! :D

Marco model bridge is 9 centimetres taller than joes model bridge. if Joe's bridge is 31 centimetres tall. write an Equation that could be used to find the height

Answers

9 + 31 = x. If Macros bridge is 9 centimeters taller than 31, you just have to do 9 + 31.

All you need to do is use the formula which is A = b x h. So, to solve, you just need to multiply 9 by 31 and I think that equals x. I'm not going to give you the answer because I want to see if you can solve it out yourself.

Update: I think I did the formula wrong. I think it's the user above who put the correct formula. Yeah, so I think you just add 9 and 31.

Anyways, just add 9 and 31 to get your answer.

What is 480 increased by 25%.
what is the new number?

Answers

The new number is 600.How do we get 600? Here’s how:
1. First, we have to get the 25% of 480.
      Multiply 480to 25%.
                   480x 25%= n
Change 25% to decimal form.
                   25/100(as per value of % symbol)
                   25% is 0.25So, 480 x 25% = n is:
                 480x 0.25 = 120
  2. Add 25% of 480 (120)and 480.
      480 + 120 =600
Therefore, when 480 is increased by 25%, it is 600.

480 * 25%480 * 0.25480 * 0.25 = 120480 + 120 = 600.480 increased by 25% is 600

Gina charges $28 for 3 hours of swimming lessons. Hector charges $18 for 2 hurs of swimming lessons. Which instructor offers a better deal?

Answers

Answer:

Hector offers a better deal: $18 for 2 hours.

Step-by-step explanation:

1. You have the following information given in the problem above:

- Ginas offers $28 for 3 hours.

- Hector offers: $18 for 2 hours.

2. Then, you must write the rates:

a) $28 for 3 hours:

$(28)/(3)=9.33$ dollars per hour.

b) $18 for 2 hours:

$(18)/(2)=9$ dollars per hour.

3. Therefore, the better deal is $18 for 2 hours

Answer:

Hector is providing best deal.

Step-by-step explanation:

Given data:

Gina charges = $28

Time by Gina = 3 hours

Hector charges = $18

Time by Hector = 2 hours

Solution:

Charges per hour by Gina = $28/3

= $9.33

Charges per hours by hector = $18/2

= $9

Hence hector charges low per hour than Gina. So hector provides the best deal.

Explanation:

Now the both instructor provides lesson with different charges with different hour. So if we calculate the charges per hour than the charges per hour Gina is charging more than hector.

Hector is charging $9 for one hour and $27 for 3 hour while Gina is charging $28 for 3 hours.

So the Hector is providing best deal.
