I'm thinking either 5 is to 3 or 45/27
Answer:
Option C is right
Step-by-step explanation:
The figure is a kite divided into 4 right triangles
Top two triangles are congruent and also bottom two triangles
Since top half angle is 45 we have height = base = 45 for top triangle
Top triangle right side area = 1/2 base x height = 1/2 (2.5)(2.5)
Area of two triangles at the top = 2.5 x 2.5 =6.25
Now bottom triangles each has base 6m and height same as 2.5 m
Hence area of two triangles at the bottom=2(1/2 )(6)(2.5)
=15
Together the total area of the figure = 6.25 +15 = 21.25 m^2
Option C is right.
The perfect square binomial expression for such would be u2 - 16u + 64. Then the factor of it would be (x-8)(x-8)
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have
see the model in the attached figure N 1
so
This is the equation of a linear direct variation
The relationship between the variables x and y is proportional
see the model in the attached figure N 2
Count the same scores and make a list:
There are two 75's
Three 80's
Two 85's
Two 90's and one 100
Now find the chart that has those same values.
The answer would be B.
