Answer:
Step-by-step explanation:
The sides of a quadrilateral always add up to 360°.
Missing angle = 360-115-97-68 = 80°
Remember that when you are making stimates, you are going to roiund to the nearest dollar. Since $3.29 is closer to 3 dollars than four dollars, Sam should use the 3 dollars figure to estimate if he can afford 4 gallons of gas.
$3+$3+$3+$3=$12
The actual value is

, so $3 per gallon is indeed a god estimate.
We can conclude that the correct answer is: <span>
$3 + $3 + $3 + $3 = 12, so Sal can afford the gas.</span>
d=2r, r = 2.5
A= πr2
Area = 3.14 ⋅ 2.5 ⋅ 2 = 15.7 
Answer:
Step-by-step explanation:
A Venn diagram depicts the logical relationships between two or more sets of elements by using alternating circles or other shapes. They're often used to visually arrange information, showing how objects are similar and different. In the fields of mathematics and statistics, Venn diagrams, also known as "set diagrams" or "logic diagrams," are commonly used.
From the given information:
Since we are to represent the given question into a Venn diagram, the diagram is being attached in the image below.
From the image below, we represent:
P =students that played Paino
G = students that played guitar
F = students that played flute
P = 50
G = 68
F = 59
(PUG) -35
(PUF) = 59
(GUF) = 40
since the value of (PUGUF) is not given, we represent it with x.
See the attached image below for diagrammatic representation of the Venn diagram.
