Answer:
y = 0.6x – 4
or
y =
3/5x
-4
Step-by-step explanation:
Answer:
A new car costs $23,000. The value decreases by 15% each year.
An exponential model to represent the car's value after t years:
y = 23000 x (1 - 15/100)^year
= 23000 x (0.85)^year

By applying the <em>volume</em> formulae for <em>composite</em> figures, cones and hemispheres, we obtain that the volume is approximately equal to 558.9 cubic centimeters.
<h3>How to determine the volume of a composite figure</h3>
The volume of the <em>composite</em> figure is the sum of the volumes of the two figures: (i) a cone, (ii) a hemisphere. The volume formula of the figure is shown below:
If we know that r = 5.3 cm and h = 8.4 cm, then the volume of the composite figure is:
V = (2π/3) · (5.3 cm)³ + (π/3) · (5.3 cm)² · (8.4 cm)
V ≈ 558.900 cm³
By applying the <em>volume</em> formulae for <em>composite</em> figures, cones and hemispheres, we obtain that the volume is approximately equal to 558.9 cubic centimeters.

Answer:
$58.50
$80
No
Step-by-step explanation:
A: 30% of $45 means we must multiply 0.30 and 45. $45 x 0.30 = $13.50 is the markup. Next, add $13.50 to $45 for a total of $58.50 to get the total amount the store will charge with the markup.
B: X = price the STORE pays for instr.
130% X = $ 104
X = 104/(130%) = 104/1.3 = $ 80
No, It would have went up by 25% because 100%-25%=75%
