Answer:
$20.
Step-by-step explanation:
Given:
In the clip from the Simpsons, Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso.
It costs $40 to travel from Tucson to Flagstaff,
And $90 to travel from Albuquerque to El Paso.
Question asked:
How much does Bart need to pay ?
Solution:
Fair to travel from Tucson to Flagstaff = $40
Fair to travel from Albuquerque to El Paso = $90
<u>As Ralph charges Bart twice the fair from Tucson to Flagstaff, minus 2/3 the fair from Albuquerque to El Paso. </u>


Thus, Bart need to pay $20.
Answer:
280 is your answer right answer
Answer:
see explanation
Step-by-step explanation:
The figure shown has one pair of parallel sides and is a trapezium
The area (A) of a trapezium is calculated using
A =
h(a + b)
where h is the height and a, b the length of the parallel sides
here h = 2w, a = w + 3 and b = 4w - 2, hence
A =
× 2w(w + 3 + 4w - 2)
= w(5w + 1) = 5w² + w
Answer:
8 Joule
Step-by-step explanation:
Mass of block = 2 kg
Displacement = x = 800 mm = 0.8 m
Spring constant = k = 25 N/m
Potential Energy of a spring
Work done = Difference in Potential Energy
Work Done = Δ P.E.

⇒P.E. = 0.5×25×0.8²
⇒P.E. = 8 Nm = 8 Joule
Here already the spring constant and displacement is given so the mass will not be used while calculating the potential energy.
