Answer:

x = 90° or π/2 rad

Step-by-step explanation:

4+ 2 sin x=14-8 sin x

2 sin x + 8 sin x  = 14 - 4

10 sin x = 10

sin x = 1

Using a calculator

x = sinsin^{-1}1

x = 90° or π/2 rad

Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?
m_a_m_a [10]

Answer:9 nickels and 19 dimes.

Step-by-step explanation:

Let n be the number of nickels Kay has.

Let d be the number of dimes Kay has.

Value of 1 nickel is $0.05

Value of n nickels is $0.05n

Value of 1 dime is $0.1

Value of d nickels is $0.1dn

Given that Kay has a total of 28 coins.

So,n+d=28                                                ...(i)

Given that Kay has a total value of $2.35

So,0.05n+0.1d=2.35                                 ...(ii)

Using (i) and (ii),

0.05n+0.1(28-n)=2.35\\0.05n+2.8-0.1n=2.35\\2.8-2.35=0.05n\\0.45=0.05n\\n=9

d=28-n=28-9=19

Help with a few questions pleaseeeeee
mel-nik [20]
29.99 * 3 =89.97 89.97 with 30% off = 62.98 and 5% of 62.98 =3.15 so 62.98 + 3.15 = 66.13$ 


180.00 + 14.95 + 8.95 = 203.09 - 15% = 173.44 + 4% = 180.38


5.65 + 5% of 5.65 = 5.93 

i think this is all right you might want to check my work!
