Answer:
201.53[tex]m^{2}[/tex]
Step-by-step explanation:
That is a hexagonal pyramid, which means it consists of one hexagon and six triangles.
Let's first find the hexagonal base.
The formula to find the area of a hexagon is [tex]\frac{3\sqrt{3}}{2}a^{2}[/tex], where a is the length of one side of the hexagon. In this question, a = 6m
Solve that to find that the area of the hexagon is 93.53m^2.
Now, on to the triangles. The area of one triangle is the base times the height, then halved. We know that the base of the triangle is 6m as it shares the base with a side of the hexagon, and the question states that the height is also 6m.
6 * 6 = 36
36 / 2 = 18
Hence, the area of one triangle is 18m^2
However, there are six triangles - not just one!
6 * 18 = 108
Adding everything up:
93.53 + 108 = 201.53
The answer is 201.53m^2

To find:
The value of the given expression.
Solution:
We have,
[tex]\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-9}{16}\times \dfrac{14}{25}[/tex]
It can be written as:
[tex]=\dfrac{-2}{3}\times \dfrac{5}{7}\times \dfrac{-3\times 3}{2\times 2\times 2\times 2}\times \dfrac{2\times 7}{5\times 5}[/tex]
[tex]=\dfrac{-2\times 5\times (-3)\times 3\times 2\times 7}{3\times 7\times 2\times 2\times 2\times 2\times 5\times 5}[/tex]
Cancel out the common factors.
[tex]=\dfrac{-(-3)}{2\times 2\times 5}[/tex]
[tex]=\dfrac{3}{20}[/tex]
Therefore, the value of given expression is [tex]\dfrac{3}{20}[/tex].

how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22
Answers
Answer:
x = 4, y = -3
Step-by-step explanation:
{2x - y = 11
{x + 3y = -5
You can use the substitution method by solving for x in the second equation:
x + 3y = -5
Subtract 3y from both sides:
x = -3y - 5
Now, substitute this value for x into the first equation:
2x - y = 11
2(-3y - 5) - y = 11
Distribute:
-6y - 10 - y = 11
Add 10 to both sides:
-6y - y = 21
Combine like terms:
-7y = 21
Divide both sides by -7:
y = -3
Next, substitute this value for x into the second equation:
x + 3y = -5
x + 3(-3) = -5
Multiply:
x - 9 = -5
Add 9 to both sides:
x = 4

The length of a living room is 12ft and it's width is 10 1/2 ft. The length of the living room is being expanded by X feet? Choose an expression to represent the new area of the living room in square feet and the expanded fotm of the expression? Select all that apply
Answers
Answer:
C. 10.5(12 + x) square feet
E. (126 + 10.5x) square feet
Step-by-step explanation:
A. 10.5(12x) square feet
B. (10.5 + 12 + x) square feet
C. 10.5(12 + x) square feet
D. 126x square feet
E. (126 + 10.5x) square feet
F. (22.5 + x) square feet
length of a living room = 12ft
width = 10 1/2 ft
The length of the living room is being expanded by X feet
New length of a living room = 12ft + x feet
new area of the living room = length × width
= 12ft + x feet × 10 1/2 ft
= (12 + x) 10 1/2
Note: 10 1/2 is equivalent to 10.5
= (12 + x) 10.5
= (126 + 10.5x) square feet
Options that applies
C. 10.5(12 + x) square feet
E. (126 + 10.5x) square feet

Answer:
x = (3-2√11)/5 ; x= (3+2√11)/5
Step-by-step explanation:
Δ/4 = (b/2)^2 - ac where b is the term that multiplies x, a is the therm that multiplies x^2 and c is the therm without x
Δ/4 = (-3)^2 - (-7*5) = 9 + 35 = 44 = 2^2 *11
x1 = (3 - √2^2 *11)/5 = (3-2√11)/5
x2 = (3+ √2^2 *11)/5 = (3+2√11)/5

What is the area of this regular polygon?
Answers
Answer:
A=25√3 cm^2
Step-by-step explanation:
Since it is a regular triangle, all sides are equal to 10cm. The dotted line is a perpendicular bisector, which means that it seperates the triangle into two perfect halves. So a right triangle is formed. The bottom of the right triangle will be half of 10, and 10/2=5. So to find the missing side, use the pythagoreom theorem.
5^2+x^2=10^2
25+x^2=100
x^2=75
x= 5√3
The height of the triangle is found, so apply the formula for area:
A=1/2*5√3*10
A=25√3

Which graph represents a quadratic function with a negative discriminant?
Choice 1
Choice 2
Choice 3
Choice 4
Answers
Answer:
Choice 4
Step-by-step explanation:
#4 because the graph does not intersect the x-axis
The graph that represents a quadratic function with a negative discriminant is graph 4.
What is a Discriminant?The part in the formula of a quadratic equation that helps us to know the nature of the roots of a quadratic equation is known as a discriminant.
D = b2 - 4ac,
If the value of the discriminant is greater than zero then the roots of the equation are real and distinct,If the value of the discriminant is equal to zero then the roots of the equation are real and same, andIf the value of the discriminant is less than zero then the roots of the equation are imaginary.Since for the value of the discriminant to be negative, the roots of the quadratic equation should be imaginary. Also, imaginary never intersects the x-axis of the graph.
Now, in the group of the graphs the only graph that does not intersect the x-axis of the graph or have imaginary roots is graph 4.
Hence, the correct option is graph4 (Bottom Right).
