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.
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.

B.) If soccer balls are sold for $14.61 each, the store will make a daily profit of $2.05.
C.) If soccer balls are sold for $2.05 or $14.61 each, the store will maximize their daily profit.
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
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.

For a = -1,
= (-1)^3 + (-1)^2 - (-1) + 7
= -1 + 1 + 1 + 7
= 8
6.
2ab(a + b) - 3ab(a - b) =
= 2a^2b + 2ab^2 - 3a^2b + 3ab^2
= -a^2b + 5ab^2
For a = 1 and b = 2,
= -(1)^2(2) + 5(1)(2)^2
= -1(2) + 5(4)
= - 2 + 20
= 18
Answer:
Step-by-step explanation:
a(a^2 + a -1) +7

f(-1)=-1+1+1+7
f(-1)=0+1+7
f(-1)=8
2ab(a+b)-3ab(a-b)

The probability that any postcard posted in Portugal on Monday is delivered to the UK within a week is 0.62.
The probability that any postcard posted in Portugal on Friday is delivered to the UK within a week is 0.41.
Anna is on holiday in Portugal. She posts 15 postcards to the UK on Monday.
How many of her postcards can she expect to be delivered within a week?
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
So, She expect 9 postcards to be delivered within a week.
Tony has $20. He wants to buy at least 4
snacks. Hot dogs (x) are $3 each.
Peanuts (y) are $2 each.
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
Instructions: Find the circumference of the circle and round to the nearest tenth.
3.2 yd.
Circumference =
yd.
Can u get help?
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.

A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the square? Use 3.14 for π, and round your answer to the nearest hundredth. 38.47 units2 94.99 units2 153.86 units2 379.94 units2
Answer:
Answer choice A) About 38.47 square units
Step-by-step explanation:
Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:
[tex]\dfrac{22}{2\pi}\approx 3.503[/tex]
Since the area of a circle is [tex]\pi r^2[/tex], the area of this circle is:
[tex]\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47[/tex]
Hope this helps!

What is the final amount if 1885 is increased by 5% followed by a further 18% increase?
Give your answer rounded to 2 DP.
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)

What is the total surface area of the figure shown?
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
