Lester played a told of 40 games this past year. He won 65% of the time he played. How many games did he lose?
Scrat [10]
"of" means multiply
So 65% * 40
65% is the same as 0.65 (% means divide by 100).
0.65 * 40 = 26
26 games

there is a 20% discount with a set of tires in normally sells for $368. How much will be tires cost after the discount?
ICE Princess25 [194]
Same as before, if we take 368 to be the 100%, how much is 20% off that?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
368&100\\
d&20
\end{array}\implies \cfrac{368}{d}=\cfrac{100}{20}\implies \cfrac{368\cdot 20}{100}=d

so, the discount is that much, thus, the discounted price is then 368 - d.

I need help with this​
kirill [66]

Answer:

88

Step-by-step explanation:

The triangles are congruent. Also, a triangle has a sum of 180 degrees for its interior angles.

Angles D and A are both unknown.

Angles O and P are both 55.

Angles G and W are both 37.

37+55 = 92

That means there would be 88 degrees left for the unknown angle to get to the total of 180 degrees.

92 + 88 = 180
