Answer:
5/8 is greater than 7/12
Step-by-step explanation:
5/8 is greater than 7/12
we need to make the denominators the same in order to solve the inequality
so, the easiest solution would be to multiply both denominators by each other, then doing that to the numerator ....
5 x 12 = 60 7 x 8 = 56
8 x 12 = 96 12 x 8 = 96
here we have our new fractions ---
[tex]\frac{60}{96}[/tex] which was originally [tex]\frac{5}{12}[/tex]
[tex]\frac{56}{96}[/tex] which was originally [tex]\frac{7}{12}[/tex]
now that we have the denominators the same... we can clearly see that
[tex]\frac{60}{96}[/tex] is greater than [tex]\frac{56}{96}[/tex]
therefore 5/8 is greater than 7/12

Grant is painting a rectangular board that has a width of 1/3 foot. He has enough paint to cover 3 square feet. If he is able to cover the while board by using all of his paint, what is the length of the board in feet.
Answer:
Length of the rectangular board=9 foot
Step-by-step explanation:
Width of the rectangular board=1/3 foot
Length of the rectangular board=x
Area of the rectangular board=3 square feet
Area of a rectangular board =Length × Width
3=x * 1/3
3=1/3x
Divide both sides by 1/3
3÷1/3=x
3*3/1 = x
9=x
x=9 feet
Therefore,
Length of the rectangular board= x = 9 foot

What’s between 16 and 18?
16, 17, 18
Not that hard
Answer:
C
Step-by-step explanation:
Los 75 postulantes que fueron aceptados tuvieron notas desde 16 hasta a 20. Si el grupo se hubiera desempeñado de modo homogéneo y hubieran tenido todos la misma nota, ¿cuál sería esa nota? 2. Si los estudiantes se agrupan según notas, ¿cuántos grupos se forman? 3. ¿Qué notas tendrían los estudiantes del grupo más grande? 4. Si los estudiantes se ordenan en fila según notas, ¿qué nota tiene el del medio?
Answer:
Tenemos 75 postulantes, y sus notas están en el rango desde 16 hasta 20.
1) si el grupo es homogéneo y todos tienen la misma nota, entonces todos van a tener la nota media en el rango (16, 20)
Para encontrar esta nota calculamos la suma entre ambos extremos y lo dividimos por 2.
Media = (16 + 20)/2 = 36/2 = 18
La nota sería 18.
2) entre 16 y 20 tenemos:
16, 17, 18, 19 y 20
tenemos 5 notas distintas, entonces si agrupamos a los estudiantes por nota, tendríamos 5 grupos.
3) En una distribución normal, el grupo mas grande debería coincidir con la media del intervalo. Ya sabemos que la media es 18, entonces es esperable que la nota del grupo mas grande sea 18.
4) Si los estudiantes se ordenan en fila según notas tendríamos:
Fila con nota 16
fila con nota 17
fila con nota 18
fila con nota 19
fila con nota 20
Podemos ver que la fila del medio es el grupo con nota de 18
if alpha beta are the roots of the equation

then the quadratic equation whose roots are alpha +beta and alpha beta is
Answer:
Step-by-step explanation:
Hello, I believe that we can consider a different from 0.
By definition of the roots we can write.
[tex]ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\<=> \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }[/tex]

values between -3 and 3 and the range is all y-values
between
-2 and 2.
Is Tatiana correct?
Answer:
no
Step-by-step explanation:
The domain and the range of a graph are simply the possible x and y values of the graph.
Tatiana is incorrect, because she switched the x and y values
From the complete question (see attachment), we have the following observations.
The y values of the graph is between -2 and 2The x values of the graph is between -3 and 3This means that:

The fill pipe for a tank can fill the tank in 15 min and the drain pipe can empty the tank in 10 min. If both pipes are accidentally opened, how long will it take to empty the full tank?
Answer:
30 min
Step-by-step explanation:
The tank can be filled in 15 min, this means that in one min, 1/15 of the tank can be filled.
The tank can be emptied in 10 min, this means that in one min, 1/10 of the tank can be emptied.
the outflow rate - the inflow rate = rate of emptying the tank
1/10 - 1/15 = 1/x
where x is the time it will take to empty the tank
solving, we'll have
1/30 = 1/x
the reciprocal of the equation gives
x = 30 min
If the surface area for the coloured tile is 286cm², find the
value of x.
pls hlp（-""-；)
Answer:
x=8.72389
Step-by-step explanation:
first you make every number 10 times larger
25*10, 48*10, etc etc
you find that you have 12x
the difference between the two surfaces is
120000 (250*480)- 28600= 91400
12x²+20=91400
12x²=91400-20
12x²= 91380
x²=91380/ 12
x²= 7615
x= √7615
x= 87.2389
and since we had made everything 10 times bigger
x=8.72389

Answer:
The numbers would be placed inside of natural numbers
Step-by-step explanation:
Such number would be placed inside natural numbers.
Integers are whole numbers and their opposites. This means that an integer can be a negative number.
Whole numbers are counting numbers, including Zero and excluding negative numbers. Therefore whole numbers are greater than or equal to 0
Natural numbers are counting numbers excluding Zero and Negative numbers.
From the above definitions, we can agree that natural numbers exists in whole numbers and also exists in integers, but neither of the two exists in natural numbers.
We can then say that
Natural numbers is a subset of whole numbers which is a subset of integers.
Natural numbers < Whole numbers < Integers.

Calculate the amount and compound interest on Rs 5000 compounded annually or 2 years 6 months at the rate of 10% per annum.
Answer:
Amount
Rs 6345.30
Compound interest
Rs 1,345.30
Step-by-step explanation:
Here in this question, we are interested in calculating the amount and the compound interest on the value given.
To calculate the amount, we use the formula below;
A = P(1 + r/n)^nt
Where; A is the amount which we want to calculate
P is the principal which is Rs 5,000
r is the interest rate per annum = 10% = 10/100 = 0.1
n is the number of times per year in which it is compounded ( since it is annually, then it is 1)
t is the number of years which is 2.5 years( kindly know that 6 months is same 1/2 year , so 6 months is same as 0.5, and thus 2 years 6 months becomes 2.5 years)
now let’s substitute all these values;
A = 5000(1 + 0.1/1)^(1*2.5)
A = 5000(1 + 0.1)^2.5
A = 5000(1.1)^2.5
A = 6,345.2935314294
This is approximately Rs 6,345.30
The second part of the question asks to calculate compound interest
Mathematically ;compound interest = Amount - principal
= 6345.3 - 5000 = Rs 1,345.30

In a farm there are ducks and rabbits. In total the sum is 24 animals. If we add all the legs we get 88. How
many rabbits are there in the farm?
please show your working
THANKS for your helping ✨✨
Answer:
There are 20 rabbits.
Step-by-step explanation:
Let D be the number of ducks on the farm and R be the number of rabbits. We get the equation:
D + R = 24
Ducks have 2 legs and rabbits have 4. We know there are 88 legs in total, so we get the equation:
2D + 4R = 88
Rewriting the first equation, we get:
D = 24 - R
Substituting this into the second equation, we get:
2(24 - R) + 4R = 88
Solve for R:
48 - 2R + 4R = 88
2R = 40
R = 20
So there are 20 rabbits and 4 ducks on the farm, with a total of 88 legs.

Let's compare the scientific notation representation of two of these numbers. 0.0000004 = 4.0 x 10 ⁻⁷ and 1,080,000,000 = 1.08 x 10⁹ Write a sentence comparing what is the same and what is different about these two numbers when they are written in Scientific Notation
Answer:
Step-by-step explanation:
Scientific notation is a quick way to represent a number using powers of base ten. This notation is used to be able to express very large or very small numbers very easily.
The numbers are written as a product:
a * 10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number. n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it shifts to the left, negative if it shifts to the right.Comparing what is equal to these two numbers when they are written in scientific notation you can see that the value of a is such that 1 ≤ a <10
Comparing what is different from these two numbers when they are written in scientific notation, you can see that the value of the exponent n in both numbers is different, one being positive, indicating that it is a very large number, and the other negative, indicating that it is It is a very small number that is between 0 and 1.
