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.
Answer:
25%
Step-by-step explanation:
The number of people who went to the local swimming pool in the;
first week = 1120
second week ( 105 fewer people) = 1120 - 105 = 1015
third week (135 more people) = 1015 + 135 = 1150
fourth week (310 fewer people|) = 1150 - 310 = 840
The percent decrease in the number of people who went to the pool over these four weeks
= (1120 - 840)/1120 * 100%
= 280/1120 * 100%
= 1/4 * 100%
= 25%
It means that the number of people who went to the local swimming pool over the 4 weeks decreased by 25%
Answer:
66 I am pretty sure
Step-by-step explanation:
6 x 2 divided by 2 = 6
6 + 6 = 12 x 10 divided by 2 = 60
add them together
60 + 6 = 66
You conjugate verbs with the pronoun 'on' the same way you conjugate verbs with pronouns 'il/elle'. "On" means "one", qs in "One can do x or y."
Answer is 145.6cents. If 1 copy is 14.56cents, it implies 10 copies = 10(14.56)
