Answer:
189
Step-by-step explanation:
The pyramid has four triangular faces and a square base.
The area of a triangle is half its base times its height. The base of each triangle is 7, and the height of each triangle is 10. So the area of each triangle is A = ½ (7) (10) = 35.
The area of a square is the side length squared. The side of the square is 7. So the area of the square is A = (7)² = 49.
The total surface area is:
A = 4(35) + 49
A = 189
Answer: neither
Explanation:
y=1/5+2/5x
y=-1/5-2/5x
For it to be perpendicular the slopes have to be opposite reciprocals and they are not. For it to be parallel the slopes have to be the same and they too are not.
I need to see the entire graph to answer this.
P parallel to q
So m<1 =m <3
3x=105
x=35

Answer:
Karen needs to spend $4.5 to buy new hair bands.
Step-by-step explanation:
Given:
Hair bands Karen have = 3
cost of 8 hair bands = $1
Total Hair bands she require = 39
Hence Number of of new hair bands require = Total Hair bands she require - Hair bands Karen have = 39 -3 = 36
we need to find how much money she need to spend to buy new hair bands.
cost of 8 hair bands = $1
Cost of 36 hair bands = money need to spend on hair bands
By using Unitary method we get;
Money spend on new hair bands = 
Hence,Karen needs to spend $4.5 to buy new hair bands.
