Answer:
See proof below
Step-by-step explanation:
Given that m = (3x-1) and n = (3x+1)
Taking the product
mn = (3x-1)(3x+1)
mn = 9x^2+3x-3x-1
mn = 9x^2 - 1
mn+1 = (9x^2-1+1)
mn+1 = 9x^2
Dividing both sides by 9
(mn+1)/9 = (9x^2)/9
(mn+1)/9 = x^2
Swap
x^2 = (mn+1)/9
This shows the required proof

Answer: 18°
Step-by-step explanation:
Let's remember that all triangles must add up to 180°
So let's take our two given angles and add them
119°+43°=162°
Now take 180° and subtract it from 162°
180°-162°=18°
Mitosis is a process by which 1 cell divides and becomes 2 cells, those 2 cells divide and become 4 cells, and so on. Write an equation for the nth term of the geometric sequence giving the numbers of cells at each stage of this process, where a1=1. Then find a10.
Answer:
An equation for the nth term is aₙ = 2ⁿ⁻¹
and a₁₀ = 512
Step-by-step explanation:
From the question, 1 cell divides and becomes 2 cells, those 2 cells divide and become 4 cells, and so on
∴The sequence will be
1,2,4, ..., n
From the formula
aₙ = a₁rⁿ⁻¹
Where aₙ is the nth term
a₁ is the first term
n is the number of terms
and r is the common ratio
From the sequence,
a₁ = 1,
r = a₂/a₁ = 2/1 = 2
∴ The nth term (aₙ) will be
aₙ = (1)(2)ⁿ⁻¹
aₙ = 2ⁿ⁻¹
Hence, an equation for the nth term is aₙ = 2ⁿ⁻¹
To find a₁₀, substitute n= 10 into the equation
aₙ = 2ⁿ⁻¹
Then
a₁₀ = 2¹⁰ ⁻ ¹
a₁₀ = 2⁹
a₁₀ = 512
∴ a₁₀ = 512
Jane bought 5 apples at $120 each. She sells them to John to make a profit of 10%. What is the selling price of each apple?
Answer:
she resells each apple for $132
Step-by-step explanation:
I multiplied 120 by 0.1 to find how much she would be marking up the price of each apple. I got the answer of $12. So then I added that $12 to $120 and got the new price of $132.
I checked my work I swear it's correct

Kirans aunt is 17 years older than kiran.
how old will kiran aunt be when kiran is 15 years old
30 years old
x years old
Answer:
Kiran's Aunt will be 32
Step-by-step explanation:
When Kiran was born her/his Aunt would be 17 as the problem says, so just add 15 to 17 to make 32; therefore Kiran's Aunt is 32 years old when Kiran is 15 years old. :)
Answer:
She would be 32 years old.

Fifty identical balls are numbered 1 through 50 and placed in a bucket. Then, a ball is randomly selected from the bucket. Select a decimal for each blank to make the sentence true.
Answer:
Blank 1: 0.12
Blank 2: 0.18
Step-by-step explanation:
Out of 50, there are 6 numbers that contain the digit 5, (5, 15, 25, 35, 45, 50)
so when you take 0.06 and multiply it by 2 (because you have to multiply 50 by 2 to get 100), you get 0.12.
For blank 2, there are 9 single digit numbers, (1, 2, 3, 4, 5, 6, 7, 8, and 9) equaling 0.09. Multiply that by 2 and you get 0.18.
