Let us assume the cost of the stereo to be = x
Percentage of sales tax paid by Amanda = 7%
Amount of sales tax paid by Amanda = $35
Then
7x/100 = 35
7x = 35 * 100
7x = 3500
x = 3500/7
  = 500 dollars
So the cost of the stereo that Amanda bought was $500. I hope the procedure is clear enough for you to understand. Using this procedure, you can solve similar problems without requiring any help from outside.

Write the expression as the sine or cosine of an angle sin(pi/7) cos(x) + cos(pi/7) sin(x)
Natasha_Volkova [10]

Answer:

\sin(\frac{\pi}{7}+x)

Step-by-step explanation:

We are going to use the identity

\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)

because this identities right hand side matches your expression where

a=\frac{\pi}{7} and b=x.

So we have that \sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x) is equal to \sin(\frac{\pi}{7}+x).

Jake's test scores are 86, 70, 72, 100, 96, and 80. What must Jake earn of his last test to earn a mean grade of exactly 85%?
kompoz [17]

Answer:

91

Step-by-step explanation:

Mean is calculated as

mean = \frac{sum}{count}

let x be his test score of his last test , then

\frac{86+70+72+100+96+80+x}{7} = 85 ( multiply both sides by 7 )

504 + x = 595 ( subtract 504 from both sides )

x = 91
