Answer:
Prism A:
Prism B:
Step-by-step explanation:
Given
See attachment for prisms
Required
Determine the surface area of both prisms
Prism A is triangular and as such, the surface area is:
Where
and
Such that a, b and c are the lengths of the triangular sides of the prism.
From the attachment;
So, we have:
Also:
So:
Prism B is a rectangular prism. So, the area is calculated as:
From the attachment
So:
5 is the whole so they skated 2/5 less than the original whole
Answer:
The total cost as $96
Step-by-step explanation:
To find the total amount find the tax amount and the tip amount
75 * 8% = 6
75 * 20% = 15
add 6 and 15 to 75 to get 96
Length is 48 ft
The perimeter of a rectangle is equal to the sum of all side’s.
2(lengths)+2(widths)= perimeter
Length=3x+4
Now given the perimeter of 140
3(3x+4)+3(x)=140
9x+12+3x=140
12x+12=140
12x=128
X= 10.7
10.7 is the width
Length=3x+4
Length =3(10.6)+4
Length=31.8+4
Length=35.8
Answer = 35.8
This can only be answered if you were given a perimeter.
