Rationalise the denominator and simplify 6/√3
⇛2√3.
Step-by-step explanation:
Given,
6/√3
The denominator is √3.
We know that
The rationalising factor of √a is √a. To rationalise the denominator of 6√√3, we multiply this by √3/√3.
⇛(6/√3)×(√3/√3)
⇛(6√3)/(√3)²
⇛(6√3)/(√3*3)
⇛(6√3)/3
⇛2√3
Hence, the denominator is rationalised.

At a certain college, the ratio to men to women is 5 to 4. If there are 2,800 men, how many women are there?
Answer:
2240
Step-by-step explanation:
braniest pls
there are 2,240 women at the college.
To find the number of women at the college, we can use the ratio of men to women given and the known number of men.
The ratio of men to women is 5 to 4, which can be expressed as 5/4.
If we know that there are 2,800 men, we can set up a proportion:
5/4 = 2,800/x
To solve for x, the number of women, we cross-multiply:
5x = 4 * 2,800
5x = 11,200
Dividing both sides by 5:
x = 11,200 / 5
x = 2,240
Therefore, there are 2,240 women at the college.

7(1 - y) = -3(y-2)
What is the answer
Answer:
[tex] \huge y = \frac{1}{4} [/tex]
Step-by-step explanation:
[tex]7(1 - y) = -3(y-2)[/tex]
Expand the terms in the bracket
That's
[tex]7 - 7y = - 3y + 6[/tex]
Add 3y to both sides of the equation
[tex]7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6[/tex]
Subtract 7 from both sides by the equation
[tex]7 - 7 - 4y = 6 - 7 \\ - 4y = - 1[/tex]
Divide both sides by - 4
[tex] \frac{ - 4y}{ - 4} = \frac{ - 1}{ - 4} \\ [/tex]
We have the final answer as
[tex]y = \frac{1}{4} \\ [/tex]

whats the distance between (1,2) and (4,-2)
Answer:
5 units
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).

a tank contains 500 litres of water. the water is leaking at a rate of 2 litres per day.
a) how long would it take for half the water to leak out?
Pls explain this and answer and workings
Answer:
125 days.
Step-by-step explanation:
How many 2 litres are there in 500?
That is 500/2 = 250.
Therefore the number of days to empty the whole tank is 250 days.
So for half to leak out it's 250/2 = 125 days.

Read the conjecture below. Select all of the true statements about this conjecture. If you multiply two numbers, then the product is greater than either number. Select all that apply. a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4. b. This conjecture is false. There is a counterexample that would prove this conjecture false. c. This conjecture is false: . d. There is not enough information.
Answer:
a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4
b. This conjecture is false. There is a counterexample that would prove this conjecture false.
Step-by-step explanation:
The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.
Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.
If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.
The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.

Think of powers of 10. Each power is 10 times larger or smaller than the last one. So in this instance, the bacterium has a diameter of 10^-6 which is 1 millionth. And then there's the virus, which has a diameter of 10^-7 which is 1 ten millionth. So basically, take 10^-7 and times that by 10. This gives you 10^-6, which can only mean that the bacterium is 10 times bigger than the virus, which is the answer on top.
A tree measured 18 feet tall. Over the next 3 1/2 years, it grew to final height of 35 1/2 feet. During those 3 1/2 years, what was the average yearly
Growth rate of the height of the tree
Answer: it 5 feet/yard
Step-by-step explanation:
The average yearly growth rate the tree is 5 feet per year.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
Given that,
Height of tree = 18 feet
Also, the tree grew in next 3 ¹/₂ years,
Since the tree grew to final height of 35 ¹/₂ or 71/2 feet.
The increased height of the tree = 71/2 - 18 = 35/2
To find the average growth rate of the height of the tree,
Use ratio method,
In 3 ¹/₂ years = 35/2 feet,
In 7/2 years = 35/2 feet,
in 1 year = 5 feet
The average growth rate of the height of the tree is 5 feet per year.

Find the 64th term of the arithmetic sequence 2, -3,-8
Answer:
-313
Step-by-step explanation:
a1=2; d=-5
a64=2-5(64-1)=-313
The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.
What is Arithmetic sequence?
An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.
Given that;
The arithmetic sequence;
⇒ 2 , -3 , -8 ...
Now,
The general equation for nth term of the arithmetic sequence is,
[tex]T_{n} = a + (n - 1) d[/tex]
Where, The term 'a' represent the first term.
And, 'd' represent the difference between each consecutive numbers.
Here, In the arithmetic sequence 2 , -3, -8;
The first term = 2
The difference = -3 - (2) = - 5
So, To find the 64th term of the arithmetic sequence, we can substitute
n = 64 and a = 2 and d = -5 in above formula as;
[tex]T_{n} = a + (n - 1) d[/tex]
[tex]T_{64} = 2 + (64 - 1) (-5)[/tex]
[tex]T_{64} = 2 + (63 * -5)[/tex]
[tex]T_{64} = 2 - 315[/tex]
[tex]T_{64} = -313[/tex]
Thus, The 64th term of the arithmetic sequence 2, -3, -8 ... will be -313.

Find the midpoint of AB if A(-3. 8) and B(-7. -6)
The midpoint of AB is (-5, 1).
To find the midpoint of a line segment AB, we average the x-coordinates of the two endpoints and the y-coordinates of the two endpoints.
Given that A has coordinates (-3, 8) and B has coordinates (-7, -6), we calculate the midpoint as follows:
x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2
= (-3 + -7) / 2
= -10 / 2
= -5
y-coordinate of midpoint = (y-coordinate of A + y-coordinate of B) / 2
= (8 + -6) / 2
= 2 / 2
= 1
Therefore, the midpoint of AB is (-5, 1), where -5 is the x-coordinate and 1 is the y-coordinate. This means that the midpoint is equidistant from points A and B, dividing the line segment AB into two equal parts.

What is subtraction?Finding the difference between two numbers is done using the subtraction technique. The size of a group of things decreases if any of the objects are removed.
For instance, at your birthday celebration, you purchased 9 cupcakes, of which your friends consumed 7. There are only 2 cupcakes remaining for you now. Nine minus seven equals two, which may be represented as the subtraction expression 9 - 7 = 2. (9 - 7) = 2 is the result of subtracting 7 from 9.
According to the question, the given values are :
There are 260 people in the graduating class in 2000, then it increased by 60.
5 years later the people class in the class was 320.
Then in the year 2010, it was 400.
So, the difference between 400 and 320 is 80.
Hence, this concludes that the greatest change will occur in 2010.
