Answer:
96 in²
Step-by-step explanation:
The surface area of the square pyramid is the area of the square base plus the area of the four triangular faces. The slant length is the height of each triangle.
A = s² + 4 (½ sL)
A = s² + 2sL
Given s = 6 and L = 5:
A = (6)² + 2(6)(5)
A = 36 + 60
A = 96
The area that needs to be painted is 96 in².
Answer:
1 and 8
2 and 7
Step-by-step explanation:
Alternate angles take form of a Z-angle.
For alternate exterior angles look for exterior angles that for Z- pattern.
The alternate exterior angles are marked in the attached diagram.
Hence the alternate exterior angles are:
1 and 8
2 and 7
Answer:
The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.
Step-by-step explanation:
Popcorn mean= μ`1= 3.06
Popcorn St. Dev= σ1= 0.02
Potato Mean= μ`2= 5.05
Potato St. Dev= σ2= 0.05
Finding the z score
z= x- u / σ
Popcorn z= 3.06- 3.03/0.02= 1.5
Potato Z= 5.05-5.07/0.05= -0.4
The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5
Choice 3 is the best option .
Answer:
54
Step-by-step explanation:
216 - 3x = 324 -5x
subtract 216 from both sides
add 5x to both sides
divide both sides by 2x.
