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 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 $x$ 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.

The sum of three numbers is 102. The first number is 6 more than the second. The third number is 4 times the second. What are th

const2013 [10]

Answer:

1st number: 22

2nd number: 16

3rd number: 64

Step-by-step explanation:

x + y + z = 102

x = 6 + y

z = 4y

plug that in!

(6 + y) + y + (4y) = 102

get rid of the parenthesis (I added them so you could see what I was replacing) and add like terms.

6 + 6y = 102

move 6 to the other side.

6y = 96

y = 16

now that you know one number, you can solve the equations for the rest!

x = 6 + (16)

z = 4(16)

__________________________________________________________

x = 22

y = 16

z = 64

There are 83 species of butterflies at a butterfly world. That is 38 more than 5/6 of the species x, found in Florida. Which equ

Brilliant_brown [7]

The equation to determine the number of species in florida is:

$38 + \frac{5}{6}x = 83 \text{ or } \frac{5}{6}x = 45$

Solution:

Given that,

There are 83 species of butterflies at a butterfly world

That is 38 more than 5/6 of the species x, found in Florida

To find: Equation used to determine the number found in Florida

From given statement,

83 species of butterflies = 38 more than 5/6 of the species x

Which can be written mathematically as,

$83 = 38 + \frac{5}{6} \times x\\\\38 + \frac{5}{6}x = 83$

Thus the equation to determine the number of species in florida is found

Let us solve the equation

$\frac{5}{6}x = 83-38\\\\\frac{5}{6}x = 45\\\\5x = 45 \times 6\\\\5x = 270\\\\x = 54$

Thus 54 species is found in florida
