Final answer
Option B is the final answer
Answer:
Surface Area = 85.75 ft²
Step-by-step explanation:
Surface area of pyramid = ½(Perimeter of triangular base * slant height of pyramid) + Area of triangular base
Perimeter of triangular base = sum of all sides of the triangular base = 5+5+5 = 15 ft
Slant height of pyramid = 10 ft
Area of triangular base = ½*base of triangle*height of triangle = ½*5*4.3 = 10.75 ft²
Plug in the above values:
Surface Area = ½(15*10) + 10.75
= (15*5) + 10.75
= 75 + 10.75
Surface Area = 85.75 ft²
Since the discount is 20%, we know that $24 is 80% or 4/5 of the original price of the shoes. Divide the $24 by 20%, and you get $6. Add that to $24, and you get the original shoe price: $30. You can verify by Multiply 30 by 80%, which comes out to the discount price-$24.
Answer:
72 units
Step-by-step explanation:
SA=2lw+2lh+2hw
SA=2(8x2) + 2(8x2) + 2(2x2) Note, Not distributive
SA= 2(16) + 2(16) + 2(4)
SA= 32 + 32 + 8
SA= 72
Answer:
Kim is 20 years old
Step-by-step explanation:
We have to make equations;
Kim= laura+10 so L+10
Laura is twice as old as Melissa so Laura will be
2 X M = 2M
<h2>Melissa is 5 years old now </h2>
Input values in to the equation
<h2>2M = 2X5= 10 years old (Laura)</h2>
As Kim is 10 years older than Laura it will be 10+10
<h3>which will give the answer of
20 </h3>
