Answer:
Pyramid
Step-by-step explanation:
Figures in the diagram:
- Triangle formed by 3 line segments
- Plane (intersecting the prism)
- Pyramid
The first two have two dimensions and the third one has three dimensions
Therefore pyramid does not belong
Answer:
8.8
I don't see that choice in this picture so I hope that those are not all the choices
Step-by-step explanation:
Lets find all the angles first, that highlighted red square means that angle is a right angle, also known as 90 degrees, and the missing angle will be represented with b, also a triangle equals 180 degrees:
48 + 90 + b = 180
138 + b = 180
b = 42
So the missing angle is 42. If u didn't know, how wide an angle is effects the length of the side that it's facing. So because one of the angle is 48 degrees, the length of the side facing it is 10. So we needed to find the missing angle first to determine x, which we already did. So lets find the scale factor, we're dividing 42 with 48:
42/48 = 7/8
Now multiply 7/8 with 10:
10(7/8) = 70/8 = 8.75 = 8.8
Answer: 372 inches
Step-by-step explanation:
Given that :
Width = 8 feets
Length = 7 1/2 feets
The inches of fencing needed is obtained by calculating the perimeter of the garden :
Perimeter of rectangle (p) : 2(length + Width)
P = 2(7 1/2 + 8)
P = 2(15 1/2)
P = 31 feets
1 foot = 12 inches
31 feets = (12 * 31 ) = 372 inches
Answer:
factor and set the factors equal to 0.
so basically - x= 6, -8
Step-by-step explanation:
Answer:
311.36
Step-by-step explanation:
For a geometric series sum of first n terms is 
if r is less than 1.
where a is the first term and r is the common ratio.
____________________________\
given
a = 108
r = 
n = 8
thus , sum of n term is
Thus sum of first 8 terms is 311.36
