Answer:
The decimal would be 0.2 or in percentages, 20/100.
Step-by-step explanation:
Answer: 1924
Step-by-step explanation:
Number if seats in the theater = 3700
Percentage of seats filled by students in the theater = 52%
The number of 6th graders that went on the trip will be gotten by multiplying 52% by 3700. This will be:
= 52% × 3700
= 52/100 × 3700
= 0.52 × 3700
= 1924
1924 students went on the trip
the key is to write as which can be easily seen as an area of a rectangle with one side length n and the other (n+1). That explains the rectangle made of dots - 3 x 4
Now you only have half of them because of the 1/2. So that explains the lower "triangle" of dots being greyed out - they do not count in the area (upper triangle). So the count of the dark dots corresponds to the original expression.
For n=5 you can draw a similar rectangular matrix with 5 x 6 dots. And count only the upper triangular part.
To find X:
-b/2a=-2/2(-2)=.5
plug in .5 to the equation to find y.
-2(.5)²+2(.5)+1
=1.5
Vertex: (.5,1.5)
Axis of symmetry:
x=.5
Answer:
so its 72÷6 so I think it would be 12
