If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume

Ann [662]

We're literally just comparing 200 to 800 here.
800 is 4× bigger than 200, of course.
To put that in a percent...
Well, 1 = 100%. (it's a whole)
So 4 = 400%

Each bowling ball weighs 7.3*10^3 grams. The bowling alley has 2.0*10^2 bowling balls. How much do they all weigh, combined? Exp

Alexandra [31]

Answer:

1.46 x 10⁶g

Step-by-step explanation:

Given parameters:

Weight of each bowling ball = 7.3 x 10³g

Number of balls in the bowling alley = 2.0 x 10²bowling balls

Unknown

The weight of the balls in the alley = ?

Solution:

To find the weight of the balls in the alley, multiply the mass of each balls with the total number of balls;

Weight of the balls = 7.3 x 10³ x 2.0 x 10²

Weight of the balls = (7.3 x 2.0) x 10³⁺²

Weight of the balls = 14.6 x 10⁵g

Therefore, the weight of the balls = 1.46 x 10⁶g

An eagle can fly at a speed of 50 mph and a starling can fly at 78 mph. How far will the starling fly in the time it takes the e

disa [49]

Well, we know the eagle does 50 miles in 1hr, how long will it be for 125 miles?

well $\bf \begin{array}{ccllll}
miles&hours\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
50&1\\
125&x
\end{array}\implies \cfrac{50}{125}=\cfrac{1}{x}\implies x=\cfrac{125\cdot 1}{50}
\\\\\\
x=\cfrac{5}{2}$

so, the eagle for 125miles does them in 5/2 hours or 2hrs and a half

now, how far will the sterling go in 2hrs and a half?

well, we know the sterling does 75 miles in 1hr

thus $\bf \begin{array}{ccllll}
miles&hours\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
75&1\\
x&\frac{5}{2}
\end{array}\implies \cfrac{75}{x}=\cfrac{1}{\frac{5}{2}}\implies \cfrac{75}{x}=\cfrac{2}{5}$

solve for "x"
