The number 1729 is the smallest number that can be expressed as the sum of two cubes in two different ways as 1729 = 12^3 + 1^3 = 10^3 + 9^3. Find two other numbers with the same property. Express them as the sum of two cubes.
Answer:
4104 and 13832
Step-by-step explanation:
This type of number is known as the Hardy-Ramanujan Number.
We have that 1729 is the first number where this is found, but there are others. The second number that meets this is:
4104
2 ^ 3 + 16 ^ 3 = 9 ^ 3 + 15 ^ 3
And we also have:
13832
18 ^ 3 + 20 ^ 3 = 2 ^ 3 + 24 ^ 3
That is to say, the numbers 4104 and 13832 comply with this property
Find five rational numbers between 3/7 and 2/3
PLEASE HELP...... I NEED TO SUBMIT THIS NOW....
Answer:
First, you get both of them with same denominator:
3/7 and 2/3 => 9/21 and 14/21, however, there are only 4 rational numbers between 9/21 and 14/21.
The solution is that you can raise the denominator 2 times:
9/21 and 14/21 => 18/42 and 28/42
Now you can select : 19/42, 20/42, 21/42, 22/42, 23/42. They are a group of 5 rational numbers you are looking for.

The sum of two numbers is 198. If one number is 20% larger than the other number, what are the numbers?
x + y = 198
y = 1.20 x
x + 1.2 x = 198
2.2x = 198
x = 198/2.2 = 90
y = 198 - 90 = 108
Answer: 90 and 108
Answer:
108 and 90
Step-by-step explanation:
let the two numbers be x and y
from the question let y be the greater number
therefore, y = 20%x +x
y=20/100x + x
y=(20x+100x)/100
y=120x/100
y=1.2x
from the question
x+y=198______(1)
x+1.2x=198
2.2x=198
x=198/2.2
x=90
from (1)
x+y=198
90+y=198
y=108
x=90 y=108

The radius of a cylindrical water tank is4.5ft , and its height is12ft . What is the volume of the tank? Use the value for , and round your answer to the nearest whole number. Be sure to include the correct unit in your answer.
Answer:
[tex]763 ft^3[/tex] or 763 cubic feet.
Step-by-step explanation:
The tank is cylindrical and the volume of a cylinder is given as:
[tex]V = \pi r^2h[/tex]
where r = radius and h = height
The radius, r, of the tank is 4.5 ft and the height, h, of the tank is 12 ft.
Therefore, the volume of the cylindrical water tank is:
[tex]V = \pi * 4.5^2 * 12\\V = 763.407 ft^3[/tex]
Approximating to whole number, the volume of the tank is [tex]763 ft^3[/tex] or 763 cubic feet.

Step-by-step explanation:
How many 2-digit numbers are multiples of either 5 or 7?
The total number of 2-digit numbers that are multiples of either 5 or 7 is 27
How many multiples of 5 are there?
The multiples of 5 end on 0 or 5, so we have:
10, 15, 20, 25,..., 95
A total of 17 numbers of 2 digits are multiples of 5.
How many multiples of 7 are there?
7*2 = 14
7*14 = 98
So there are 14 - 2 = 12 multiples of 7 in the range.
Such that:
7*5 = 35
7*10 = 70
So there are 2 common multiples of 5 and 7.
Then the total number of 2-digit numbers that are multiples of either 5 or 7 is:
17 + 12 - 2 = 27

a cone has the height of 20 centimeters and a volume of 4,170 cubic centimeters. what is the area of the base of the cone
Answer:
625.5 cm^2
Step-by-step explanation:
The volume of a cone is
V = 1/3 B h
4170 = 1/3 B 20
4170 = 20/3 B
Multiply each side by 3/20
4170 *3/20 = B
625.5 = B
Hey there! I'm happy to help you!
The formula for the volume of a cone is V=1/3(πr²h). Now, to make it look ungibberishy and all numbery...
The volume of the cone is equal to the area of the base (the circle on the bottom whose area formula is pi multiplied by the radius squared) multiplied by the height and then divided by three.
In our case, though, we already have the volume. We need to undo the equation so that we can find the area of the circle base.
In our equation the last thing we do is divide by three. So, we will want to multiply by three to undo this.
4,170*3= 12510
The other step we took was multiply the base by the height, which is 20 centimeters. To get our base, we will divide by the height instead!
12510/20= 625.5
Therefore, the area of the base of the cone is 625.5 centimeters squared.
I hope that this helps! Have a wonderful day!

About how many times greater is the volume of the cylinder than the volume of the cone?
Your answer is 3 times larger.
The volume of any cone is 1/3 the volume of the cylinder that could be formed around that cone, therefore the volume of any cylinder is 3 times larger than the volume of the cone that could fit inside.
We know this is true because the equation for the volume of a cone is (1/3) πr²h, and the equation for the volume of a cylinder is πr²h

Consider the following system.
y = 4x - 1
y = -3x + 6
Find the solution by using substitution.
HINT: Equal them to each other, solve for x. Then plug in x to one equation to find y.
Answer:
x=1 y=3
Step-by-step explanation:
y = 4x - 1
y = -3x + 6
Set the two equations to each other
4x - 1 = -3x + 6
Add 3x to each side
4x +3x - 1 = -3x+3x + 6
7x-1 =6
Add 1 to each side
7x-1+1 = 6+1
7x= 7
Divide each side by 7
7x/7 = 7/7
x=1
Now we can find y
y = 4x-1
y = 4(1)-1
y = 3

Convert 315º to radians:
Answer:
degrees ⋅(π radians /180 degrees )
the (π180) means that for every π radians you go around the unit circle, you've gone 180 degrees.
315 degrees ⋅(π radians /180 degrees )
315 and 180 are both divisible by 45 , so.
74⋅π radians = 74π radians.

There are 16 pieces of fruit in a basket, including 2 nectarines. What is the probability that a randomly selected piece of fruit will be a nectarine? Type your answer as a fraction in simplest form.
Answer:
The probability is 1/8
Step-by-step explanation:
We have 2 nectarines in a total of 16 pieces of fruit in a basket, so the probability of random selected piece of fruit being a nectarine is the number of nectarines over the total number of pieces of fruit:
Probability = Number of nectarines / Total pieces = 2 / 16
To find the fraction in the simplest form, we divide the numerator and denominator by 2:
Probability = (2/2) / (16/2) = 1/8
Answer:
its actually 3/8 trust me

Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a rectangular prism.The swimming pool takes the shape of a rectangular prism, and we are required to find the volume of the pool.
Given data
length l = 100m
width w= 25m

The mk family orchard has 120 apple trees and 90 pear trees. If each fruit tree produces an average of 590 pounds of fruit per year, about how many pounds of fruit can the orchard produce in one year
Answer & Step-by-step explanation:
If each fruit tree produces an average of 590 pounds of fruit, then that means we are going to multiply. For the apples, we are going to multiply 120 by 590. For the pears, we are going to multiply 90 by 590. After we multiply these numbers, we are going to add the products so we can find the total amount of pounds of fruit.
Apples:
120 × 590 = 70800
Pears:
90 × 590 = 53100
Now, we add 70800 to 53100.
70800 + 53100 = 123900
So, the orchard produces 123900 pounds of fruit in one year.
