Answer:6 17/18 hours
Step-by-step explanation:
We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.
The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:
= 2 1/6 + 4 7/9
= 2 3/18 + 4 14/18
= 6 17/18
She used a total of 6 17/18 hours studying
To find the diameter, you use the formula: 2x. we use 2x because the radius is 2 times the diameter.
so, if the radius is 3,980, then we substitute that into the formula.
2(3,980)
this will give us 7960. the diameter is 7960 miles.
What you have to do is divide 35 by 5 to find one fith. You can see that one fith of the class is 7 so 14 pupils in the class is boys.
