How to do lond division 0.6÷0.0024
1 answer:
So...notice first off, the 0.6 has 1 decimal, the 0.0024 has 4 decimals
what happens is, the dot goes poof BUT, you need to add as many zeros to each number as the other's decimals.
the 0.6 has one decimal, so 0.0024 gets an added zero and loses the dot, to become 000240.
the 0.0024 has four decimals, thus the 0.6 gets added 4 zeros then, and loses the dot, to become 060000
and then you divided that, those are the dividend and divisor.

7 more year 9 students than year 8 students should be surveyed, If Mr.Ford wants to survey 50 of these students stratified by year group.
Step-by-step explanation:
The given is,
Year Students
7 80
8 110
9 160
Total 350
Mr.Ford wants to survey 50 of these students stratified by year group.
Step:1
Formula to find the ratio of number of grouped students to total students,
=
= 0.1428
Step:2
Formula for Number of students surveyed from year wise,
For year 7 students,
= (Ratio) × (Students from year 7)
= 0.1428 × 80
= 11.424
≅ 11 (∵ For students we convert into whole number)
For year 8 students,
= (Ratio) × (Students from year 8 )
= 0.1428 × 110
= 15.708
≅ 16 (∵ For students we convert into whole number)
For year 8 students,
= (Ratio) × (Students from year 9 )
= 0.1428 × 160
= 22.8
≅ 23 (∵ For students we convert into whole number)
Step:3
To find How many more year 9 students than year 8 students should be in the survey
= ( Students from year 8 for group) -
( Students from year 8 for group)
= 23 - 16
= 7 students
Result:
7 more year 9 students than year 8 students should be surveyed, If Mr.Ford wants to survey 50 of these students stratified by year group.
Answer:
The slope remains a constant as it is parallel.
Explanation:
1. Line Q is defined as a slope of ; i.e.
2. Line R is defined to be parallel of Line Q.
3. Line Q is linear and has no domain restrictions.
The definition of being parallel requires the same slope.
