A farmer has a truckload of watermelons to take to market. At the beginning of the trip, the watermelons weigh 1000 kg. 99% of t

Mariulka [41]

Answer:

The weight of watermelon at the end of the trip is <u>500 kg.</u>

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 $x$ kg of water has been evaporated. So, remaining weight of the watermelon is $1000-x$ .

If $x$ 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.

Three friends, Ana, Jack and Nick come together to purchase a special from a pizza place. It is a half pepperoni, half mushrooms

maw [93]

Answer:

Paula would choose the side with all of the mushrooms and half of the pepperoni. She wont choose any sausage because she doesn't like it, but luckily David likes sausage twice as much as mushroom so he's fine with getting all of the sausage and half of the pepperoni. They both equally like pepperoni so it makes sense for them to share.

luda_lava [24]

Answer:

Step-by-step explanation:

Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight

X - number of people who need correction for their eyesight

X is binomial since each event is independent and there are only two outcmes.

X (18, 0.72)

Required probability = the probability that no more than 1 of them need correction for their eyesight.

=P(X=0)+P(X=1)=0.00000296+0.000137

=0.00014

Yes 1 is a significantly low number as probability is almost zero.

Please help to prove parallelogram.

tino4ka555 [31]

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.

<h3>What is a mathematical proof?</h3>

Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.

<h3>What is the proof that WV = VR?</h3>

Note that SR ║ QT;

Reason: This is given. The image is a parallelogram.

Hence, ∠PSR = ∠WVP
Reason: Alternate angles formed by two parallel lines crossing each other

Hence, SV = PVReason: This is given by the annotation on the image

Therefore: ΔSVR ≅ PVW

Reason: They are formed by two parallel lines crossing each other.

Therefore if ΔSVR ≅ PVW;

Then WV = VR.
