bija089 [108]

Given that, according to sanitation departments report; the samount of garbage produced by 1 resident $= 1.643 \times 10^3$ pound.

Given that population of the city $= 2.61 \times 10^5$

Now we have to find how much garbage did the city sanitation department collect last year.

To find that we just need to multiply the garbage produced by 1 resident with the population of the city.

Total garbage collected $= (2.61 \times 10^5 ) * (1.643 \times 10^3 )$ pounds

Total garbage collected $= (2.61*1.643) \times 10^{5+3}$ pounds

Total garbage collected $= 4.28823 \times 10^8$ pounds

Hence final answer is $4.28823 \times 10^8$ pounds.

A tile mosaic in the shape of a right triangle is used as the corner for a rectangular pathway. The hypotenuse of the mosaic is

Anit [1.1K]

Answer:

The lengths of the sides are 2.2 ft and 4.5 ft

Step-by-step explanation:

Let

a -----> the length of one side of the mosaic

b ----> the length of the other side of the mosaic

c ----> the hypotenuse of the mosaic

we know that

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$ -----> equation A

we have

$a=2b$ -----> equation B

$c=5\ ft$ -----> equation C

substitute equation B and equation C in equation A and solve for b

$5^{2}=(2b)^{2}+b^{2}$

$25=5b^{2}$

$b=\sqrt{5}=2.2\ ft$

Find the value of a

$a=2b$ ------> $a=2\sqrt{5}=4.5\ ft$

therefore

The lengths of the sides are 2.2 ft and 4.5 ft
