There were 200 melons in a box and they were distributed to 3 children in the ratio of 4:3:3. The first child sold the melons at 2$ each while the other two sold the melons at 2 for 5$. find the total amount of money collected fro. the sales of all melons.
Answers
Answer:
$460
Step-by-step explanation:
let the number of melons be x
4x + 3x + 3x = 200 melons
10x = 200 so, x will be 20
4x = 80 melons
3x = 60
3x = 60
amount made by 1st child = 80 × $2 = 160$
the remaining melons are 60 + 60 = 120
amount collected: they sold them in groups of 2 and each group was $5. so,
120÷2 × $5 = $300
total amount = 300 + 160 = $460.

Answers
Answer:
The price of the socks is dollar 8
Pls mark nrainliest
Answer:
$8
Step-by-step explanation:
Using the information we already know, we can form an equation:
Let x be the socks' original price.
[tex](24+x)[/tex] × [tex]0.75=24[/tex]
Divide both sides by 0.75
[tex]24+x=32[/tex]
Subtract 24 from both sides

Here is the histogram of a data distribution. All class widths are 1.
4
3-

What is the median of the distribution?
Answers
Answer: Option C, the median is 5.
Step-by-step explanation:
The median is the value that is just in the middle of our data set (the possible values in the histogram)
the set is S = {2, 3, 4, 5, 6, 7, 8, 9}
And if we take in account the number of times that each value is repeated, we get:
S = {2, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6, 7, 7, 8, 9}
So we have 17 values, and the one exactly in the middle will be the median.
To find the point in the middle, we can use that we have 17 values, because 17 is odd, we can do
17 - 1 = 16
16/2 = 8.
17 - 8 = 9.
Then the 9nth point is our median:
the 9th point is a 5.
Then the correct option is C
What is the final amount if 1885 is increased by 5% followed by a further 18% increase?
Give your answer rounded to 2 DP.
Answers
Answer:
Answer = 2,335.52
Step-by-step explanation:
Given amount : 1,885
Finding 5% of 1,885 = 0.05 * 1,885
5% of 1885 = 94.25
Now 1885 increased by 5% = 1,885 + 94.25= 1,979.25
Finding further 18% of 1,979.25 = 0.18 * 1,979.25
18% of 1979.25 = 356.265
Final amount = 1,979.25 + 356.265
Final Amount = 2,335.515
Now Rounding off the answer to 2 decimal points we get:
Answer = 2,335.52
(As the third digit after decimal is 5 so previous will be added b 1)

Tony has $20. He wants to buy at least 4

Peanuts (y) are $2 each.
Answers
Tony has $20. He wants to buy at least 4
snacks. Hot dogs (x) are $3 each.
Peanuts (y) are $2 each.
Answer:
To solve the above question, we use the below inequality equations
x + y ≥ 4 snacks .........Inequality equation 1
3x + 2y ≤ $20 ..........Inequality equation 2
Step-by-step explanation:
We can make use of the inequality equations
Hot dogs = (x) are $3 each.
Peanuts = (y) are $2 each.
He wants to buy at least 4
x + y ≥ 4 snacks .........Inequality equation 1
3x + 2y ≤ $20 ..........Inequality equation 2
From the above inequality equations, Tony can buy at least 4 snacks but he can only spend $20.
Let take a random number, where x = 4, and y = 4. This means Tony can buy
a) 4($3) + 4($2) = 12 + 8 = $20
The total number of snacks = 4 + 4 = 8 snacks.
b)
This answer above confirms the inequality equations 1 and 2
x + y ≥ 4 snacks .........Inequality equation 1
8 snacks ≥ 4 snacks
3x + 2y ≤ $20 ..........Inequality equation 2
$20 ≤ $20
Answer:
4 is the first one and the second one is ---->
Total Price: 3x + 2y ≤ 20
Step-by-step explanation:
Let's complete the inequalities that represent Tony's situation.
Given:
Tony wants to buy at least 4 snacks.
Hot dogs (x) are $3 each.
Peanuts (y) are $2 each.
We can form the following inequalities:
Total Snacks: Tony wants to buy at least 4 snacks, which can be represented by the inequality:
x + y ≥ 4
This inequality ensures that the sum of hot dogs (x) and peanuts (y) is greater than or equal to 4, indicating that Tony wants to buy at least 4 snacks in total.
Total Price: To represent the total price, we need to consider the cost of each snack. Hot dogs are $3 each, and peanuts are $2 each. Thus, the total price can be represented by the inequality:
3x + 2y ≤ 20
This inequality accounts for the total cost of the snacks Tony wants to buy. The left-hand side represents the cost of x hot dogs ($3 each) and y peanuts ($2 each), and the inequality ensures that the total cost does not exceed Tony's available budget of $20.
Therefore, the completed inequalities are:
Total Snacks: x + y ≥ 4
What is the total surface area of the figure shown?
Answers
Answer:
Surface area of the figure = 1000 in²
Step-by-step explanation:
From the figure attached,
Two rectangular prisms A and B have been shown with the dimensions.
Surface area of a rectangular prism = 2(length + width) × height
Surface area of prism A = 2(9 + 10) × 20
= 760 in²
Surface area of prism B = 2(15 + 10) × 8
= 16×25
= 400 in²
But one surface of prism B along the width and the same area of prism A are hidden.
Area of the hidden surfaces = 2(10 × 8)
= 160 in²
Total surface area of the figure = 760 + 400 - 160
= 1000 in²

How many of her postcards can she expect to be delivered within a week?
Answers
Answer:
She expect 9 postcards to be delivered within a week.
Step-by-step explanation:
We are given that The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62
We are also given that The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Now we are supposed to find How many of her postcards can she expect to be delivered within a week if She posts 15 postcards to the UK on Monday.
So, The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week =0.62
She expect no. of postcards to be delivered within a week.= [tex]15 \times 0.62[/tex]
She expect no. of postcards to be delivered within a week.=9.3

D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Answers
Answer:
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Step-by-step explanation:
Let us assume x = selling price of each soccer ball
y = daily profit earned from selling of soccer balls
Given that
Y= [tex]-6x^2+100x-180[/tex]
where,
a = -6
b = 100
c = -180
Now we have to applied the formula which is as follows
x [tex]= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
[tex]= \frac{-100\pm\sqrt{100^2-4\times -6\times -180}}{2\times -6}$[/tex]
[tex]= \frac{-100\pm\sqrt{10,000 - 4,320}}{-12}$[/tex]
[tex]= \frac{-100\pm\sqrt{5.680}}{-12}$[/tex]
[tex]= \frac{-100 + 75.3658}{-12}$[/tex]
[tex]= \frac{24.6342}{-12}[/tex]
x^1 = -2.05285
Now
x^2 [tex]= \frac{-100 - 75.3658}{-12}$[/tex]
[tex]= \frac{- 175.3658}{-12}[/tex]
x^2 = 14.6138
Based on this the option D is most appropriate as per the given situation
Answer:
If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.

Answers
Answer:
100 kilometers per hour.
Step-by-step explanation:
Since he covered a distance of 250 km in a time range of 2 and a half hours, his average speed in kilometers per hour is 250 / 2.5, which is 100 kilometers per hour.
Answer:
100km / hr
Step-by-step explanation:
Given That:
Time = between 6.00 and 8.30 = 2 1/2 hours
Distance = 250 k m
We Know that :
Speed = Distance divided by time.
Unit of speed, appropriate here = km/h
thus, Speed = 250/2.5 = 100km/hr.

Answers
Answer:
the answer is 20.1 yd
Step-by-step explanation:
circumference= 2πr
where r is 3.2
pi is 22/7
c = 2/1 × 22/7 × 3.2/1
c = 140.8/7
c = 20.1 yd
The circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle shown in the picture.
The radius of the circle = 3.2 yd
As we know,
The circumference of the circle can be calculated using the formula:
C = 2πr
Here,
C is the circumference of the circle
r is the radius of the circle
r = 3.2 yd
C = 2π(3.2)
Take π = 22/7
C = 6.4π(22/7)
C = 140.8/7
C = 20.114
After round to the nearest tenth:
≈ 20.12 yd.
Thus, the circumference of the circle is 20.12 yd. if the radius of the circle is 3.2 yd the answer is 20.12 yd.
