Answer: it might be 0.22 or 0.50
Step-by-step explanation:
cause i did 22/100 and 50/100 and got these answer one of them might be right or both of them are wrong. This is what i think so.
Answer in fraction form: x = 55/4
Answer in decimal form: x = 13.75
Both forms are equivalent, but they say it in a slightly different way.
===========================================================
Work Shown:
AC/QY = CD/YW
(x+5)/15 = 5/4
4(x+5) = 15*5
4x+20 = 75
4x = 75-20
4x = 55
x = 55/4
x = 13.75
------------
Explanations:
- The first step is possible because the polygons are similar. Similar figures have their corresponding sides be in the same proportion or ratio. Note how side AC has the double red angle (at point A) and a single red angle (point C). The side QY has the same idea in the same order. This is why AC corresponds to QY. The ratio AC/QY is the same as CD/YW.
- In the second step, I plugged in the expressions that the diagram shows. This is the substitution property.
- On step 3, I cross multiplied. The general format is A/B = C/D cross multiplies to A*D = B*C.
Answer:
The sum of 8 and 1 is 9.
lol
Step-by-step explanation:
The answer is A because it is quartile 1 of 4. There are 4 quartiles so logially 1 out of 4 is 25%. Hope this helps!
16 - (-15) = 16 + 15 = 31...difference of 31 degrees
