X = 25.5 mm.
Using the similarity statement given, that ΔABC ~ ΔDEF, we set up a proportion:
8.5/x = 4/12
Cross multiply:
4*x = 8.5*12
4x = 102
Divide both sides by 4:
4x/4 = 102/4
x = 25.5
Hey there! I'm happy to help!
We have 110 minus a certain percent of 110 equals 88. Let's call this percent p and solve.
110-110p=88
We subtract 110 from both sides.
-110p=-22
We divide both sides by 110.
p=0.2
Therefore, the percent decrease is C) 20%.
Have a wonderful day! :D
Answer:
<h2>25.96%</h2>
Step-by-step explanation:
Givens
- The old record is 6.75 meters.
- The new record is 8.5 meters.
If 6.75 meters represents 100%, which percentage would represents 8.5 meters? (we use the rule of three).
Then, we subtract 125.96% - 100% = 25.96%
Therefore, the percentage between the two records is 25.96%
The answer to your question is 24.
