The Volume of pyramid is 19.5 [tex]m^{3}[/tex].
What is pyramid?A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.
What is volume of pyramid?The volume of a pyramid refers to the space enclosed between its faces.
Volume of pyramid = (1/3) (Base area * height of pyramid )
According to the question
Area of the base = 6.8 [tex]m^{2}[/tex]
Height of the pyramid = 8.6 m
now,
using the formula of Volume of pyramid
Volume of pyramid = (1/3) (Base area * height of pyramid )
substituting the values
Volume of pyramid = (1/3) ( 6.8 * 8.6 )
= 19.49 [tex]m^{3}[/tex]
Rounding off to nearest tenth of a cubic meter
Volume of pyramid = 19.5 [tex]m^{3}[/tex]
Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

The perimeter and the ratio of the length to the width of a rectangle are given. Find the length and width of the rectangle.
Perimeter: 50 inches.
I:w=3:2
Answer:
Step-by-step explanation:
Ratio = 3 : 2
Length =3x
Width = 2x
Perimeter = 50 inches
2*(length + width ) = 50
2* (3x + 2x ) = 50
2* 5x = 50
10x = 50
x = 50/10
x = 5
Length = 3*5 = 15 inches
Width = 2*5 = 10 inches

You guys are Smart, Answer me this. But I need It fast-
Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90

The length of a rectangle is 2 inches less than three times its width. If the perimeter of the rectangle is 108 inches, find its length and width.
Answer:
the length is 40 inches
the width is 14 inches
Step-by-step explanation:
We start by representation with variables
let l be the length and w the width
Length l is 2 inches less than 3 times width (3w)
l = 3w-2 ••••(i)
Mathematically,
we have the perimeter calculated as follows;
P = 2(l + w)
2(l + w) = 108
l + w = 108/2
l + w = 54 ••••••(ii)
Substitute equation i into ii
3w-2 + w = 54
4w = 54 + 2
4w = 56
w = 56/4
w = 14
Recall;
l + w = 54
14 + l = 54
l = 54-14
l = 40 inches

Answer:
x = 3
LP = 3.5
Step-by-step explanation:
JK and LK are chords of the circle each of 7 units long.
Therefore,
JK = LK
Equal chords are equidistant from the center of the circle.
So,
PS = NS
4x - 6 = 6
4x = 6 + 6
4x = 12
x = 12/4
x = 3
LP = LK/2 ( Perpendicular dropped from the center of the circle to the chord bisects the chord)
LP = 7/2
LP = 3.5 units

Answer:
$3.50
Step-by-step explanation:
1) 4 friends each bought a movie ticket = 7.50 * 4 = 30
2) subtract from total cost = 58 - 30 = 28
4) total number of candy boxes is 8 (because each friend bought 2 boxes so 4*2 is 8) = 28/8 = 3.5
5) money so = $3 dollars and 50 cents
Exit Ticket Anyone Can help me?
Answer:
okay, so 1 1/6 can be converted to 7/6.
2 3/8 can be converted to 19/8
now find a common denominator, which is 24
7/6 would turn into 28/24
19/8 would turn into 57/24
now add! 28+57= 85/24
85/24

In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female
Answer:
93/100
Step-by-step explanation:
In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female
Number of Freshman = 60
Number of female = 55
Number of Freshman female 22
Total number of students = 100
The probability that a student picked from this group at random is either a freshman or female
Thus P(freshman or female) = 60/100 + 55/100 - 22/100 = 93/100

In right triangle XYZ, angle Y is a right angle. What is the relationship between angles X and Z? What is the relationship between sin X and cos Z?
a) Angles X and Z are supplementary, and sin X= cos Z
b) Angles X and Z are complementary, and sin X= cos Z
c) Angles X and Z are supplementary, and sin X= 1 - cos Z
d) Angles X and Z are complementary, and sin X= 1 - cos Z
Answer:
B
Step-by-step explanation:
The angles of X and Z are supplementary and sinX and cosZ will be the same hence, option (b) will be correct.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
Given that in triangle Y is 90° since in any triangle sum of all three angles will be 180° so remaining angle Z and Y will be total of 90° hence these will be complementary.
In right angle triangle sinX = cosZ because the perpendicular for X act like a base for Y.
