\\ \rm\hookrightarrow tan50=\dfrac{a}{27}

\\ \rm\hookrightarrow 27tan50=a

\\ \rm\hookrightarrow a=27(1.2)

\\ \rm\hookrightarrow a=32.4

And

\\ \rm\hookrightarrow sin50=\dfrac{32.4}{c}

\\ \rm\hookrightarrow c=32.4/1.2

\\ \rm\hookrightarrow c=27

A piggy bank contains $5.60 in nickels and dimes. The number of nickels is 8 less than 3 times the dimes. How many nickels and d
Irina-Kira [14]

Answer:

64 nickels and 24 dimes are there in the piggy bank.

Step-by-step explanation:

There are  $5.60 in the piggy bank in nickels and dimes.

Let x number of nickels and y number of dimes are there.

Now, 1 nickel ≡ 0.05 dollars and 1 dime ≡ 0.1 dollars.

So, 0.05x + 0.1y = 5.6

⇒ 5x + 10y = 560

⇒ x + 2y = 112 ....... (1)

Again, from the condition given we can write that,

So, 3y - 8 = x ........ (2)

Now, solving (1) and (2) we get 3y - 8 + 2y = 112

⇒ 5y = 120

⇒ y = 24  

And from equation (2) we get x = 3y - 8 = 64.

So, there are 64 nickels and 24 dimes in the piggy bank. (Answer)
