To solve 58 x 29 using an area model, we break down the numbers into tens and ones, use these as dimensions in the area model, and add up the areas to find the product. The product of 58 x 29 is 1682.
To solve 58 x 29 using an area model, we will break down the numbers into tens and ones. Both 58 and 29 can be written in a different form: 58 = 50 + 8 and 29 = 20 + 9.
Next, we divide the area model (or grid) into 4 parts having the dimensions 50 x 20, 50 x 9, 8 x 20, and 8 x 9. Multiply these dimensions together to get 1000, 450, 160, and 72 respectively.
The last step is to add all those areas together, which gives 1000 + 450 + 160 + 72 = 1682. So, the product of 58 x 29 is 1682 using the area model method.

Its 248,000 miles according to my math
arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20
Answer:
D. 11/20
Step-by-step explanation:
7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.
D. 11/20
