Answer:
n = 1/5
Step-by-step explanation:
Let's solve your equation step-by-step.
5(n− 1 /10 )= 1/ 2
Step 1: Simplify both sides of the equation.
5(n− 1 /10 )= 1 /2
(5)(n)+(5)( −1 /10 )= 1/2
(Distribute)
5n + −1 /2 = 1 /2
Step 2: Add 1/2 to both sides.
5n + −1 /2 + 1 /2 = 1 /2 + 1 /2
5n=1
Step 3: Divide both sides by 5.
5n /5 = 1 /5
n= 1 /5

range [0,3)
Step-by-step explanation:
The domain is the input or x values
-3 < x ≤3
in interval notation
The parentheses means not include, the bracket means include

Enter the solutions from least to greatest. -2x^2 -9=-107
Answer:
x = -7, 7
Step-by-step explanation:
Step 1: Write out equation
-2x² - 9 = -107
Step 2: Add 9 on both sides
-2x² = -98
Step 3: Divide both sides by -2
x² = 49
Step 4: Square root both sides
x = ±7
Step 5: Arrange
-7 < 7
So x = -7, 7
Use the equation below to find y, if m=5, x= 7, and b = 4.
y=mx+b
Answer:
y = 39Step-by-step explanation:
y=mx+b
m = 5
x = 7
b = 4
Substitute the values into the above expression and simplify to solve for y
That's
y = 5(7) + 4
y = 35 + 4
We have the final answer as
y = 39

the area of a rectangular field is 18000m^2 if the ratio of length and breath is 5:4 find its perimeter
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{540 \: m}}}}}[/tex]
Step-by-step explanation:
Let the length and breadth be 5x and 4x respectively.
Area of rectangular field = 18000 m²
Finding the value of x
Area of rectangle = [tex] \sf{l \times b}[/tex]
Plug the values
⇒[tex] \sf{18000 = 5x \times 4x}[/tex]
Calculate the product
⇒[tex] \sf{18000 = 20 {x}^{2} }[/tex]
Swap the sides of the equation
⇒[tex] \sf{20 {x}^{2} = 18000}[/tex]
Divide both sides of the equation by 20
⇒[tex] \sf{ \frac{20 {x}^{2} }{20} = \frac{18000}{20} }[/tex]
Calculate
⇒[tex] \sf{ {x}^{2} = 900}[/tex]
Squaring on both sides
⇒[tex] \sf{x = 30}[/tex]
Replacing the value of x in order to find the value of length and breadth
Length = [tex] \sf{5x = 5 \times 30 = 150 \: m}[/tex]
Breadth = [tex] \sf{4x = 4 \times 30 = 120 \: m}[/tex]
Finding the perimeter of the rectangular field
Perimeter of rectangle = [tex] \sf{2(l + b)}[/tex]
plug the values
⇒[tex] \sf{2(150 + 120)}[/tex]
Distribute 2 through the parentheses
⇒[tex] \sf{300 + 240}[/tex]
Add the numbers
⇒[tex] \sf{540 \: m}[/tex]
Hope I helped !

what is the solution to the equation k- 4 3/4 = 8 1/4
Answer:
k = 13Step-by-step explanation:
[tex]k - 4 \frac{3}{4} = 8 \frac{1}{4} [/tex]To solve first change the mixed number to an improper fraction
That's
[tex]4 \frac{3}{4} = \frac{19}{4} [/tex][tex]8 \frac{1}{4} = \frac{33}{4} [/tex]So we now have
[tex]k - \frac{19}{4} = \frac{33}{4} [/tex]Move the fraction to the right side of the equation
That's
[tex]k = \frac{33}{4} + \frac{19}{4} [/tex]Since they have the same denominator we can add them directly
We have
[tex] \frac{33}{4} + \frac{19}{4} = \frac{52}{4} = 13[/tex]we have the final answer as
k = 13Hope this helps you
Dita mempunyai pensil sebanyak 10 kotak.Setiap kotak berisi 36 pensil. Pada hari ulang tahunnya, ia membagikan semua pensilnya sama banyak kepada 9 temannya. Berapa banyak pensil yang diterima masing-masing temannya
Answer:
40 pensil
Step-by-step explanation:
Dari pertanyaan di atas, kita diberitahu bahwa:
Dita memiliki 10 kotak pensil
1 kotak pensil = 36 pensil
10 kotak pensil =
Cross Multiply
10 × 36 = 360 pensil.
Dari pertanyaan tersebut, kami diberitahu bahwa Dita memiliki 9 orang teman dan ia membagikan semua pensilnya secara merata kepada mereka di hari ulang tahunnya.
Jumlah pensil yang diterima setiap teman dihitung sebagai:
360 pensil ÷ 9 teman
= 40 pensil.
Oleh karena itu, setiap teman mendapat 40 buah pensil.
Simplify: 108÷36 of 1/4 + 2/5 x 13/4
A) 123/10 B) 133/10 C)41/20 D) 123/20
Answer:
B
Step-by-step explanation:
soln
=108 ÷36×1/4+2/5×13/4
=108÷9+2/5×13/4
=12+2/5×13/4
=12+13/10
=133/10✅
Consider the exponential function f(x) = b^x, where b ≠ 1. Explain WHY the base has such a restriction.
If b = 1, then the function would be a straight line, f(x) = 1 which isn't exponential.

What is the sum of 12 - and its additive inverse?
Hi
a number is additive inverse if the sum =0
so 0 as the additive inverse of 12 would be -12.
and the additive inverse of -12 is 12 (it works both ways)
The sum of number 12 and the additive inverse of 12 is given by the equation A = 12 - 12 = 0
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number be n = 12
Now , the additive inverse of the number 12 = -12
So , the sum of 12 and -12 is given by the equation ,
A = 12 - 12
A = 0
Therefore , the value of A is 0
Hence , the sum of the two numbers is 0
