The weight of watermelon at the end of the trip is 500 kg.

Step-by-step explanation:

Given:

The weight of watermelons is 1000kg.

At the beginning of the trip watermelon is 99% of the weight:

99% of 1000kg

$\frac{99}{100}\times 1000$

$=0.99\times 1000$

= 990 kg

Now, at the end of the trip it is 98% of weight. So, let kg of water has been evaporated. So, remaining weight of the watermelon is 1000-x .

If kg of water is removed, then the amount of water left is 990-x .

As per question, water now weighs 98% of the total weight. So,

98% of ( 1000-x ) = 990-x

$\frac{98}{100}\times (1000-x)=990-x$

980-0.98x=990-x

-0.98x+x=990-980 (Bringing like terms on one side)

$0.02x=10\\x=\frac{10}{0.02}=500\ kg$

Therefore, the weight of watermelon at the end of the trip is given as:

Weight = 1000 - x = 1000 - 500 = 500 kg

Therefore, the watermelon weighs 500 kg at the end of trip.

Answer from: JvGaming2001

500 kg

Step-by-step explanation:

At the beginning of the trip, the watermelons weigh 1000 kg.

99% of this weight is made up of water.

So, in 1000 kg of watermelons there are 990 kg of water and 10 kg of solid.

If after the trip due to dehydration x kg of the weight reduces, then in (1000 - x) kg of watermelons there are 10 kg of solid and (990 - x) kg of water.

Now, given that the % of the water in the load is 98%.

So, we can write that $\frac{990 - x}{1000 - x} = \frac{98}{100}$

⇒ 99000 - 100x = 98000 - 98x

⇒ 2x = 1000

⇒ x = 500

Therefore, the track load at the end of the trip will be (1000 - x) = 500 kg. (Answer)

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
