Answer:

255 miles

Step-by-step explanation:

\boxed{\sf Distance= Speed \times Time}

Journey <u>before</u> lunch:

  • Speed = 55 mph
  • Time = 3 hrs

\implies \sf Distance = 55 \times 3=165\: miles

Journey <u>after</u> lunch:

  • Speed = 45 mph
  • Time = 2 hrs

\implies \sf Distance = 45 \times 2=90\: miles

<u>Total miles driven</u>

= distance traveled before lunch + distance traveled after lunch

= 165 miles + 90 miles

= 255 miles

Therefore, the Ramos family drove 255 miles in total.

Answer:

ok so first they drove 55 for 3 hours so

55*3=165

and then they drove 45 for 2 hours

45*2=90

165+90=255

so in total they drove 255 miles

Th the mean of the data is set 15 what number is missing<br> 18,16_,9,12,23
Wittaler [7]

Answer:

The missing number on the given data set is 12.

Step-by-step explanation:

Here, the set of data = 18,16_,9,12,23

Let us assume the missing number in the data = m

The mean of the data = 15

Total number of observations   = 6

Now, Sum of the data  = 18 + 16 + m + 9+ 12+ 23  = 78 + m

Also, \textrm{ Mean of the given Data}  = \frac{\textrm{Sum of all observation in the data}}{\textrm{Total number of observations}}

\implies 15 = \frac{78+ m}{6} \\or, 15(6) = 78 + m\\\implies m = 90 -78 = 12

or, m  = 12

Hence, the missing number on the given data set is 12.

What is the total number of digits required in numbering a book that has 1724 pages?
Reptile [31]

Answer:

5,789

Step-by-step explanation:

I got 5,789 because there are 9 one digit numbers. 1-9 -> 9x1=9. There are 90 two digit numbers. (10-99)-> 90x2=180. There are 900 three digit numbers. (100-999)-> 900x3=2700. There are 725 four digit numbers. (1000-1724)-> 724x4= 2900. Then, I added 9+180+2700+2900=5789.

In conclusion, the total number of digits required in numbering a book that has 1724 pages is 5789.
