Answer:
Step-by-step explanation:
4/12
First off, this can be reduced since both the
numerator and denominator are divisible by 4
4/12 = (4(1))/(4(3)) = 1/3
Any fraction equivalent to 1/3 will be equivalent to 4/12
... And, of course, 1/3 is equivalent to 4/12 ...
Any number or fraction does not change in value if
multiplied by 1. This means you can take your 1/3
or 4/12 and multiply it by any fraction equivalent to
1 and have an equivalent fraction..
Also note that any number divided by itself equals 1
so a/a = 1 for any given value a except a≠0
(1/3)(2/2) = 2/6
(1/3)(3/3) = 3/9
(1/3)(-2/-2) = -2/-6 = 2/6
(1/3)(4/4) = 4/12 as we know since this is the original fraction
(1/3)(5/5) = 5/15
....
....
1/3, 2/6 , 3/9, 5/15, 6/18, 7/21, ....
There are infinite equivalent fractions to 4/12.

Step-by-step explanation:
Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62
Answer:
Step-by-step explanation:
The answer is 27.62

Answer:
Step-by-step explanation:
(27) [tex]7x^2[/tex] + 9x + 2
= [tex]7x^2[/tex] + 7x + 2x + 2
= 7x(x+1) + 2(x+1)
= (7x+2)(x+1)
(29) [tex]8x^2[/tex] - 2x - 1
= [tex]8x^2[/tex] - 4x +2x - 1
= 4x(2x-1) +1(2x-1)
= (4x+1)(2x-1)
(31) [tex]15x^2[/tex] - 16x - 7
= [tex]15x^2[/tex] + 5x - 21x - 7
= 5x(3x + 1) - 7(3x+1)
= (5x-7)(3x+1)

A study was conducted comparing the speeds of 2 different fish, Fish A and Fish B. The table shows the distance, in meters, Fish A travels in seconds. Scientists
concluded that Fish B travels 3 meters every 2 seconds.
Assuming both fish swim at a constant rate, which fish swims faster and by how many meters per second?
Answer:
Fish A travels faster and by 0.1 meters per second.
Step-by-step explanation:
According to the table, you can see that the seconds are not being measured constantly. To determine the rate of change of meters per second, we can use subtraction on both the numerator and denominator of the expression. Where we divide it into 1 second.
meters/second → 4.8 – 1.6 / 3 – 1 = 3.2 / 2 =
1.6 meters/second.
Now we can compare the rate from fish B by also diving it into 1 second.
3 meters every 2 seconds → 3/2 =
1.5 meters/second.
Since 1.6 > 1.5, Fish A is faster!
And to compare the simplified rates
1.6 – 1.5 = 0.1 meters.
So Fish A is 0.1 meters faster!

Answer:
138.2
Step-by-step explanation:
find area of small circle and subtract from area of big circle
A=pi*r^2
A=pi*12^2
A=144pi
A=pi*r^2
A=pi*10^2
A=100pi
144pi-100pi=44pi
44pi=138.2
Answer:
Step-by-step explanation:
Area of shaded region = A of outer circle - A of inner circle
r of outer circle = 12 cm
r of inner circle = 10 cm
Now,
As we know, area of circle = [tex]\pi r^2[/tex]
=> [tex](\frac{22}{7} * 12^2) - (\frac{22}{7} * 10^2)[/tex]
= 452.57 - 314.28
= 138.29 cm sq
Round off to nearest tenth = 140 cm sq

Let theta be an angle such that cos(theta)=-1/9 and 0<=theta<=2pi
Assume that cos(theta/2)<0. Then if
Terminal point of theta/2 = (a_1, a_2),
enter a_1 and a_2 in that order.
Using the cosine half angle formula,
[tex]\cos \frac{\theta}{2}=-\sqrt{\frac{1-\frac{1}{9}}{2}}=-\frac{2}{3}[/tex]
Using the sine half angle formula,
[tex]\sin \frac{\theta}{2}=\sqrt{\frac{1+\frac{1}{9}}{2}}=\frac{\sqrt{5}}{3}[/tex]
So, [tex]a_1=-\frac{2}{3}[/tex] and [tex]a_2=\frac{\sqrt{5}}{3}[/tex].

Answer:
Step-by-step explanation:
Both are similar as they result of both is same. The only difference is their methods of solving them. In numeric expressions, it takes long calculation while in algebraic expressions, we break the expression and then solve it to obtain the result in simpler form.

A rectangular patio has an area of 2x² + 13x — 24 ft2. Use factoring to find possible dimensions of the patio. The patio is to be enlarged so that each dimension is 2 ft greater than it was originally. What are the new dimensions of the patio? What is the new area of the patio?
Answer:
Step-by-step explanation:
[tex]2x^2[/tex] + 13x - 24 to be factorised to find the dimensions:
[tex]2x^2[/tex] + 13x - 24
= [tex]2x^2[/tex] + 16x - 3x - 24
= 2x(x+8) - 3(x+8)
= (2x-3)(x+8)
Length = (2x-3)
Breadth = (x+8)
∴ Increasement in length = 2x - 3 +2 = (2x -1)
Increasement in breadth = x + 8 + 2 = (x+10)
