It would take her 12 minutes because if you mutipy 2/3 by 3/2 then you get 1 (as in one mile) and then you have to do that to the other side too so then you multiply 8 by 2/3 and get 12
Answer:
12 minutes
Step-by-step explanation:
<u>50 miles</u> = <u>10 miles</u> << Equivalent
1 hour = x << fraction
You divide 50 by 5 to get 10,
so to get the number of minutes for 10 miles,
divide 60 by 5.
(1 hour = 60 minutes, 60/5 = 12)
Answer:
SA = 52900 + 2300√1313 m²
Step-by-step explanation:
The equation of the surface area of a pyramid:
SA = area of base + 0.5 * perimeter of base * slant height
1. Area of the base: Since it's a square base, 230² m² = <em>52900 m²</em>
2. Perimeter of the base: The base is square, 230*4 m = <em>920 m</em>
3. Slant height: 115² + 140² = h² --> h² = 32825 --> h = <em>5√1313 m</em>
Plug in: SA = 52900 + 0.5 * 920 * 5√1313
Multiply: SA = 52900 + 2300√1313 m²
