8 0

Answer:

638.32 yd²

Step-by-step explanation:

The surface area of any figure can be found by calculating the area of all the sides and finding the sum. In a rectangular pyramid, there is a rectangular base (l x w) and the same two triangles on one side and another two identical triangles on the other side.

Area of rectangle: A = l x w

Area of a triangle: A = 1/2(b)(h)

Rectangle: 16 x 13.4 = 214.4 yd²

Bottom/top triangles: 14.1 x 16 = 225.6 yd²

Side triangles: 14.8 x 13.4 = 198.32 yd²

Total: 198.32 + 225.6 + 214.4 = 638.32 yd²

It takes Harrison 1 1/2 hours to finish his history project it takes Miles 3 2/3 hours to finish his science project. How many t

solniwko [45]

Answer: The answer is $2\dfrac{4}{9}~\textup{times}.$

Step-by-step explanation: Given in the question that

Time taken by Harrison to finish his history project is given by

$t_1=1\dfrac{1}{2}=\dfrac{3}{2}~\textup{hours}.$

and the time taken by Kiles to finish his science project is

$t_2=3\dfrac{2}{3}=\dfrac{11}{3}~\textup{miles}.$

Let the time taken by Miles to finish his science project be 'p' times that of the time taken by Harrison to finish his history project.

Therefore,

$t_2=p\times t_1\\\\\Rightarrow p=\dfrac{t_2}{t_1}=\dfrac{\frac{11}{3}}{\frac{3}{2}}=\dfrac{11}{3}\times \dfrac{2}{3}=\dfrac{22}{9}=2\dfrac{4}{9}.$

Thus, Miles take $2\dfrac{4}{9}$ times more time than Harrison.
