Answer: P=1.2
Step-by-step explanation:
-4.6p-6.3p+3.9=-9.18
simplify
-10.9p+3.9=-9.18
-10.9p=-13.08
p=1.2
We know that Santa's favorite snack used to cost $1.45 a box and the cost has gone up 15%. We must calculate the new price.
To calculate the new price we must calculate the 15% of the old price and then add up the old price and its 15%.
1. We must calculate the 15% of the old price
2. we must add up the old price and its 15%
Finally, the price now is $1.6675
2/5 of 50 is 20. 20 campers like to hike.
Answer:
Step-by-step explanation:
1, Find (g-f)(x)
we know (g-f)(x) = g(x) - f(x) = ( 5x -2) -( 2x^2 +3x +6)
= 5x -2 - 2x^2 - 3x - 6
= -2x^2 + 2x -8
So the function (g-f)(x) = - 2x^2 + 2x - 8
2, Find (fg)(x)
we know that (fg)(x) = f(x) * g(x)
= (2x^2 +3x +6 ) *( 5x -2)
= 5x* (2x^2 +3x +6 ) - 2*(2x^2 +3x +6 )
= 10x^3 + 15x^2 +30x -4x^2 -6x - 12
= 10x^3 + 11x^2 + 24x - 12
The answer is (fg)(x)= = 10x^3 + 11x^2 + 24x - 12
Answer:
Volume = 0.1696 L
The formula is Area of base of refraction cup × Depth of the refraction cup
Step-by-step explanation:
The dimensions of a refraction cup are;
Diameter = 120 mm
Depth = 30 mm
Therefore, volume of the refraction cup = Area of base × Depth
Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³
1 L = 1000000 mm³
Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L
The formula is Area of base of refraction cup × Depth of the refraction cup.
