Answer:

Step-by-step explanation:
let a be the number of tennis balls.
let b be the number of tennis rackets.
We write determine the ratio of balls to rackets by dividing the number of balls by the number of rackets:

For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;
of students only saw jewelry collection
<em><u>Solution:</u></em>
Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs
7/8 of the students saw either the jewelry collection or the dinosaurs
<em><u>To find: Fraction of students only saw jewelry collection</u></em>
From given statement,
Fraction of students saw dinosaur = 
Fraction of students saw either the jewelry collection or the dinosaurs = 
Therefore,
Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur

Thus
of students only saw jewelry collection
<em>x</em> and <em>w</em> are parallel lines, so
• angles 2 and the one labeled 75º are congruent because they are alternating interior angles, and
• angles 1 and 2 are supplementary because they form a linear pair.
The first observation tells you that angle 2 has measure 75º, and angle 1 has measure <em>m</em> such that
<em>m</em> + 75º = 180º
so angle 1 has measure 180º - 75º = 105º.
