The chocolate chip cookies of the cookie's club are not perfect according to Wendy, as the ratio of the chocolate chips to the cookies is more than that of a perfect cookie.
To solve this problem we have to learn about ratio. A ratio is an ordered pair written as or a:b where
. It can also be defined as the number of times one number is contained in another number.
In the given problem Wendy thinks that a 353535 chocolate chips are essential for 555 cookies so that each cookie is perfect. Now let us find the ratio of the chocolate chips for each cookie.
Ratio=
or, Ratio=637:1
Therefore according to Wendy, a perfect chocolate chip cookie must have 637 chocolate chips.
Now let us find the ratio of the chips to cookie of the Cookie's Club.
Total chocolate chips=100100100
Total cookie=151515
Ratio of chips to cookies= which can be simplified to
.
Therefore required ratio=
or, approximately ratio=
Now
Therefore the chocolate chip cookies of the cookie's club are not perfect according to Wendy.

Answer:
Step-by-step explanation:
The given triangle is a right angled triangle.
So, the angles in the triangle are :
Solving according to <u>angle sum property</u>,
Sum of all angles in a triangle is 180°
90° + (2x + 38)° + (5x - 11)° = 180°
117° + 7x = 180°
7x = 180° - 117°
7x = 63°
x = 9
Angles =
2(9) + 38
56°
5(9) - 11
34°
The angles are 56°, 90° and 34°.
