Answer:
50%
Step-by-step explanation:
because that say each square represent a Whole that is 100%
and each triangle represents the 1/2 Of a whole that is 50%
The percent is 50% because as you see that it is only shading half of that square!
We can't give you the direct answer but note: Well we cannot give the direct answers, this a a big part in the question, you can see that it gives 50% but there is also the other whole sqaure :)
Can someone help me please and thank you ( i'll give brainliest and extra points)
Which table represents a quadratic function?
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Which equation can be used to solve for x in the parallelogram below?
A) 3x-12=6x+12
B) (7x-8)+(6x+12)=90
C) 3x-12=2x+8
D) (7x-8)+(6x+12)=180
Answer:
B. (3x - 12)° = (2x + 8)°
Step-by-step explanation:
This equation can be used to solve x.
3x - 12 = 2x + 8
3x - 2x = 12 + 8
x = 20°

Verification:
3(20) - 12 = 2(20) + 8
60 - 12 = 40 + 8
48° = 48°

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
VolumeVolume is the amount of space that is occupied by a three dimensional object.
The volume of a cone (V) is given by:
V = (1/3)πr²h
Where r is the radius and h is the height.
For a radius of 1:
3π = (1/3)π*(1)² * h
h = 9
For a radius of 2:
3π = (1/3)π*(2)² * h
h = 2.25
For a radius of 5:
3π = (1/3)π*(5)² * h
h = 0.36
For a radius of 12:
3π = (1/3)π*(12)² * h
h = 0.02
The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
