(predicted value - exact value)/exact value * 100
(31 - 34)/34 * 100 = 8.8%
Answer:
6 pairs of socks
Step-by-step explanation:
I started with $15.99 and subtracted that by $21.93. $21.93-$15.99= $5.94. Then I divided $5.94 by $0.99. $5.94/$0.99= 6. I hope this helped
2/3 ÷ 4
2/3 ÷ 4/1
We invert the 4/1 to 1/4 and multiply out.
2/3 × 1/4
= 1/3 × 1/2 2 into 4 is 2.
= 1/(3 × 2)
= 1/6
Hope this helps.
Answer:
18m
Step-by-step explanation:
Since the given traingles are similar
We get
![\frac{JK}{MN} = \frac{KL}{ML}](https://tex.z-dn.net/?f=%20%5Cfrac%7BJK%7D%7BMN%7D%20%3D%20%20%5Cfrac%7BKL%7D%7BML%7D%20)
![\frac{JK}{42} = \frac{21}{49}](https://tex.z-dn.net/?f=%20%5Cfrac%7BJK%7D%7B42%7D%20%20%3D%20%20%5Cfrac%7B21%7D%7B49%7D%20)
![JK = \frac{21 \times 42}{49}](https://tex.z-dn.net/?f=JK%20%3D%20%20%5Cfrac%7B21%20%5Ctimes%2042%7D%7B49%7D%20)
![JK = \frac{3 \times 7 \times 6 \times 7}{7 \times 7}](https://tex.z-dn.net/?f=JK%20%3D%20%20%5Cfrac%7B3%20%5Ctimes%207%20%5Ctimes%206%20%5Ctimes%207%7D%7B7%20%5Ctimes%207%7D%20)
![JK = 3 \times 6 = 18](https://tex.z-dn.net/?f=JK%20%3D%203%20%5Ctimes%206%20%3D%2018)
![JK = 18](https://tex.z-dn.net/?f=JK%20%3D%2018)
Hence the distance across river is 18m
