Write the number equal to 5 tens and 13 ones
serious [3.7K]
To find this out we have to add 5 tens and 13 ones. 
5 tens is equal to 
10 + 10 + 10 + 10 + 10 = 50 

And 13 ones is equal to 
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 13 

Now add 50 and 13 
50 + 13 = 63

So your answer is 63 

good Luck! :)

son4ous [18]

Answer:

The mean of the combined group is 76.67 ≈ 77

Step-by-step explanation:

  1. The sum of the grades in Tom's group is 20×70 = 1400
  2. The sum of grades in Alice's group is 10×90=900
  3. The sum of gradees in the combined group is =1400+900=2300
  4. Then the mean grade of the combined group is \frac{2300}{30}=76.67

where

  • 2300 is the sum of the all grades in the combined group
  • 30 is the total number of people in the group
