EF = 15 cm.
Step-by-step explanation:
Step 1:
If the quadrilaterals, ABCD and EFGH are similar their side lengths will be of the same ratio throughout.
Comparing the quadrilaterals, we have AB and EF are similar, BC and FG are similar, CD and GH are similar, DA and HE are similar.
So the ratio of all these sides will be equal.
Step 2:

Of these lengths, we only have the values for AB, BC, CD, DA, GH, HE and need to determine the length of EF. By substituting the known values the ratio becomes;


So
cm. Which is the second option.
She spent 21 minutes completing the math problems. But then you add the 9 minutes she spent checking. Your answer is 30 minutes in total
Step-by-step explanation:
1. use the equation
current amount X interest to the power of years
commpound interest is 2.3%
The starting value is £7900
So: £7900*1.023^5=£8851.26
Therefore, the answer is £8851.26 after 5 years of interest added
Hope this helps!!!
