Answer:
2/7=0.285714
3/7=0.428571
4/7=0.571428
5/7=0.714285
6/7=0.857142
Step-by-step explanation:
1/7 = 0.142857
2/7=2(1/7)
2/7=2(0.142857)
2/7=0.285714
3/7=1/7+2/7
3/7=0.142857+0.285714
3/7=0.428571
Or
3/7=3(1/7)
3/7=3(0.142857)
3/7=0.428571
4/7=2(2/7)
4/7=2(0.285714)
4/7=0.571428
5/7=5(1/7)
5/7=5(0.142857)
5/7=0.714285
6/7=2(3/7)
6/7=2(0.428571)
6/7=0.857142
Answer:
6
Step-by-step explanation:
5+1
a negative and a negative make a positive.
=6
Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10
The answer is 4*\sqrt(2), or 5.7 if rounded to the nearest tenth digit. Notice that this is a right triangle (F is the right angle). The length of FG and FE are both 4 units on the diagram. Therefore, according to the Pythagorean theorem, the length of EG is \sqrt(4^2+4^2)=4*\sqrt(2), which is about 5.7.
