We are given that popularity of television is inversely proportional to its cost.
let us say popularity of television is represented by "P" and cost of television by "T".
We will use a constant "k" to convert the proportionality sign to equal to (=) sign.
Thus forming the equation :
We are given that 15 customers buy a television that cost $1500.
plugging P=15 and T=1500, finding k,
k=15*1500 = 22500
Next we have to find how many customers would buy a television that costs $2500, so here k=22500 and T=2500, plugging this in the equation we have ,
P=9
So there will be 9 customers that buy a television which costs $2500.
Answer:
48.8°
Step-by-step explanation:
We solve using sine rule
The formula is given as
p/sin P = r/sin R
In APQR, P = 83°, p = 285 m, r = 216 m.
Calculate R.
Hence, solving for R
285/sin 83 = 216/sin R
Cross Multiply
285 × sin R = sin 83 × 216
sin R = sin 83 × 216/285
R = arc sin (sin 83 × 216/285)
R = 48.78527°
Approximately = 48.8°
Therefore, R = 48.8°
Answer:
x > -4
Step-by-step explanation:
— 3х + 7 < 19
Subtract 7 from each side
— 3х + 7-7 < 19-7
-3x < 12
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 12/-3
x > -4
Answer: x=−1
Step-by-step explanation: Hope this help :D
-y\3=-3\5-x\5
multiply all sides by 3
-y=-9\5-3x\5
divide all sides by -
y=9\5+3x\5
