You set a goal of creating a $16,000 emergency fund. You earn a salary of $40,000 per year
and decide to save 20% of your gross pay. How long will it take for you to achieve your goal?
A. 6 months
B. 1 year
C. 2 years
D. 3 years
Answer:
the answer is C. 2 years
20% of 40000 is 8000, remember that gross pay is for the end of the year not monthly
Step-by-step explanation:
It will take 2 years for you to achieve your goal. which is the correct answer would be an option (C).
Given that,
You set a goal of creating a $16,000 emergency fund. You earn a salary of $40,000 per year and decide to save 20% of your gross pay.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Calculating 20% of the gross pay:
⇒ 20% of 40,000 = 0.20(40,000) = 8000
Since the set a goal of creating a $16,000 emergency fund.
So the required time will be :
⇒ 16,000/ 8000 = 2
Thus, it will take 2 years for you to achieve your goal.

Select all the expressions which have 3 as the greatest common factor of the terms.

12x + 75y + 21
–32 – 24z
Answer:
27n+66p and 12x+75y+21
Step-by-step explanation:
The greatest common factor is 3 for 27n + 66p and 12x + 75y + 21.
What are Factors?Factors of a number or an algebraic expression are the numbers or expressions which divides the given number evenly.
For example, 10 = 2 × 5
So we can say that 2 and 5 are factors of 10.
Greatest common factor of two numbers or expressions, as the name suggests is the greatest of all the common factors of the given numbers or expressions.
Consider 27n + 66p
Factors of 27n are 1, 3, 9 and 27
Factors of 66p are 1, 2, 3, 6, 11, 22, 33 and 66
Greatest common factor of both = 3
Consider 12x + 75y + 21.
Common factors of three of them are 1 and 3.
Greatest common factor is 3.
Hence the expression with greatest common factor as 3 are 27n + 66p and 12x + 75y + 21.

What is the prime
factorization of 200
using exponents?
The prime factorization of 200 with exponent is 23*52.
Factoring involves finding two numbers that, when multiplied together, yield the original number. But often we can factor these two factors into smaller numbers, and even find the factors of these smaller numbers. Prime factorization divides a number into a series of prime numbers and allows them all to be multiplied to equal the original number.
First, find the prime factorization of 200.
(200=2*100) (200=2*100)
(200=2*2*50) (200=2*2*50)
(200 = 2 * 2 * 2 * 25) (200 = 2 * 2 * 2 * 25)
(200 = 2 * 2 * 2 * 5 * 5) (200 = 2 * 2 * 2 * 5 * 5)
Then group similar factors together.
(2∗2∗2)∗(5∗5)(2∗2∗2)∗(5∗5)
Hence, we write the prime factorization list, but we represent the grouped factors by writing the base factors and adding exponents of the number of times they are repeated.

The line of symmetry divides the quadratic graph into 4 parts
Answer:
The line of symmetry divides the quadratic graph into 4 parts
Step-by-step explanation:
The line of symmetry divides the quadratic graph into 2 parts, not 4 parts.
Since a quadratic parabola is symmetrical on two sides, the line of symmetry divides it into these 2 parts.
So, this statement is not true.

Brandon is going to invest in an account paying an interest rate of 5% compounded quarterly. How much would Brandon need to invest, to the nearest dollar, for the value of the account to reach $490 in 16 years?
Answer:
Brandon wants $490 in 16 years by investing "x" dollars in an account that pays 5% compounded quarterly. How much is "x"?
Principal = Total / [ (1 + (r/n) )^ n * years]
n = 4 (for compounded quarterly)
Principal = 490 / [ (1. + (.05/4)) ^ 4 * 16]
Principal = 490 / [ (1.0125)^ 64]
Principal = 490 / 2.2145324106
Principal = 221.2656710971
So, if we invested 221.27 for 16 years at 5% compounded quarterly interest, we would have a total of $490.00

m is the slope
b is the y-intercept
Given the coordinate points (2, 1) and (-1, 3)
m = 3-1/-1-2
m = 2/-3
m = -2/3
Determine the y-intercept
1 = -2/3(2) + b
1= -4/3 +b
b = 1 + 4/3

Find the equation of the line using Point-slope formula. Write the final equation using slope-intercept form. Perpendicular to 7y=x-4 and passes through the point (-2,2).
The equation of the line using point-slope formula is y-2=-7(x+2) and the final equation using slope-intercept form is y=-7x-5
For two perpendicular lines, m1m2=-1
The line is 7y=x-4
1/7.m2=-1
m2=-7
The equation taking help of point slope form is
y-2=-7(x-(-2))
y-2=-7x-7
y=-7x-7+2
y=-7x-5 (using slope intercept form y=mx+b)
It passes through (-2,2) and is perpendicular to the given line 7y=x-4
The perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees.If two non-vertical lines in the plane intersects at a right angle then they are said to be perpendicular.To learn more about perpendicular lines visit:
