How many of the numbers from 10 through 97 have the sum of their digits equal to a perfect​ square?
Anarel [89]
Perfect squares are:
1,4,9,16,25,36,49,64,81,100,....

the sum of the digits of our biggest number is 16 so any perfect square bigger than 16 doesn't work for us
1-
1+0=1 so any number containing the digits will work(keep in mind we only will look into whole numbers because digits can't be negative or have fractions or be irrational)
thereful 10 works for our category
2-
0+4=4
1+3=4
2+2=4
22 13 31 and 40 will work two
3-
0+9
1+8
2+7
3+6
4+5
90 18 81 27 72 36 63 45 54

2+14
3+13

Mr. Miles has 7 7/8 pounds of clay to make 3 models. He uses 2 1/10vpounds to make each model. Mr. Miles says he has about 3 pou
Kitty [74]
Answer:
Mr. Miles’s statement is NOT reasonable

Explanation:
If Mr. Miles uses 2 1/10 pounds of clay for each model, Mr. Miles will have used a total of 6.3 pounds of clay.
The decimal form of 7 7/8 is 7.875, so 7.875 minus 6.3 will give you the amount of clay Mr. Miles has left over.

7.875 - 6.3 = 1.575

This means that Mr. Miles statement is not reasonable, as he only has about 1.6 pounds of clay left, not 3.
