Step-by-step explanation:
8). 5 ft² into squared Inches:
=> since 1 ft² = 144 in²
=> 5x144
=> 720 in²
9). 16 000 cm² to m²:
=> since 1 m²= 10 000 cm²
=> 16 000 ÷ 10 000
=> 1.6 m²
10). 90 km/h to m/h
=> since 1000 m= 1 km
=> 90x1000
=> 90 000 m/h
11). 30 m/s to m/min
=> since 60 s= 1 min
=> 30÷60
=> 0.5 m/min
12). 15 rpm into rps
=> since 1 min= 60 s
=> 15x60
=> 900 rps
Richmond County has a population of 850,000 people, which increases by 10% every year
due to a growing tech industry. What will the population be in 2 years?
If necessary, round your answer to the nearest whole number
Answer:
If the current population is 850,000. Next year it will be 935,000, and the year following that it will be 1,028,500. This is a linear growth (its growth has a common ratio).
Answer:
1,028,500 people
Step-by-step explanation:
When finding the percentage of a number you moved the decimal place over twice and then multiply.
850,000 x 0.10 = 85,000
10% of 850,000 is 85,000
I then found the population of the 1st year
85,000 + 850,000 = 935,000
then I found 10% of that 1st year
935,000 x 0.10 = 93,500
then added 85,000 and 93,500 to find the population growth in the 2 years
85,000 + 93,500 = 178,500
Then added the population growth to the original population
178,500 + 850,000 = 1,028,500 people

after being rearranged and simplified, which equation could be solved using the quadratic formula
A. 4x+2=0
B. 3x2-4=3x^2-4x
C. 2x=32
D. 5x^2+8x-12=2x2-x
Option D
5x²+8x-12=2x²-x5x²-2x²+8x+x-12=03x²+9x-12=0x²+3x-4=0Now we can apply quadratic formula to find two zeros
Answer:
[tex]\textsf{D.}\quad5x^2+8x-12=2x^2-x[/tex]
Step-by-step explanation:
Quadratic Formula
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0[/tex]
A linear equation in the form [tex]y=mx+b[/tex] cannot be solved using the quadratic formula, as it is not a quadratic equation.
[tex]\textsf{A.}\quad 4x + 2 = 0[/tex]
This is a linear equation and therefore cannot be solved using the quadratic formula.
[tex]\begin{aligned}\textsf{B.}\quad 3x^2-4&=3x^2-4x\\\implies -4&=-4x\end{aligned}[/tex]
This is a linear equation and therefore cannot be solved using the quadratic formula.
[tex]\textsf{C.}\quad 2x=32[/tex]
This is a linear equation and therefore cannot be solved using the quadratic formula.
[tex]\textsf{D.}\quad5x^2+8x-12=2x^2-x[/tex]
[tex]\implies 3x^2+9x-12=0[/tex]
Therefore, this is a quadratic equation in the form [tex]ax^2+bx+c=0[/tex] and therefore can be solved quadratic formula.
a = 3, b = 9 and c = -12
Inputting these into the quadratic formula and solving for x:
[tex]\begin{aligned}\implies x &=\dfrac{-(9) \pm \sqrt{(9)^2-4(3)(-12)}}{2(3)}\\\\x& = \dfrac{-9 \pm \sqrt{225}}{6}\\\\x& = \dfrac{-9 \pm 15}{6}\\\\x&=\dfrac{6}{6},\dfrac{-24}{6}\\\\x&=1, -4\end{aligned}[/tex]

Answer:
im not sure i got stuck here ;; but i started sort of
Step-by-step explanation:
The first step is to get the inner angles. I'll start with the one at 60 degrees and call it A and go counter clockwise
A flat angle is 180 and -60 makes it 120 = Angle A
180-100=80=B
180-20=160=C
Then when you're trying to calculate a figure with more than 4 corners, you're supposed to divide them into triangles. Now we have a hexagon and the total degrees is 720. And we know that we have 2 6x and they're the angles
Select all expressions that represent a correct solution to the equation 6(x+4)=20
A. (20−4) ÷ 6
B. 16(20 − 4)
C. 20 − 6 − 4
D. 20 ÷ 6 − 4
E. 1/6(20 − 24)
F. (20−24) ÷ 6
Answer:
D. 20 ÷ 6 − 4
E. 1/6(20 − 24)
F. (20−24) ÷ 6
Step-by-step explanation:
6(x + 4) = 20
6(x) + 6(4) = 20
6x + 24 = 20
- 24 - 24
6x = -4
/6 /6
x = -4/6 or x = -2/3
D. 20 ÷ 6 − 4
20/6 - 4
20/6 - 24/6
-4/6 = -2/3
E. 1/6(20 − 24)
1/6(-4)
-4/6 = -2/3
F. (20 − 24) ÷ 6
- 4 / 6
-4/6 = -2/3

Urgent fastttttttttttttttttttttttttttt 50 points

*PLS HELP!!* {The Picture Is In The Attachment}
Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
Answer:
supplementary means that < 1 and 50° together must be equal to an angle of 180°
so 180° - 50° = 130°
the second one its the same.. 50° + < 3 = 180°
so 180° - 50° = 130°
so you find out that < 1 = < 3
..if this m is meant like x and therefore this is an equation
m < 1 = m < 1 / ÷ < 1
m = m and that is true..
There were 150 students wearing red shirts today. If there are a total of 300 students at school, about how many out of a class of 30 could be wearing red shirts?
Answer:
I think it's 15 students
Step-by-step explanation:
i think since 150 is half of 300 so in each class there should also be half of the people wearing red
Answer:
150 of 300, 150 is 50 % of 300 so 300/30 = 1 , so I think 15 of the students should be wearing red

4. Jackie obtains a 30-year 4/2 ARM at 5% with a 4/7 cap structure in the amount of $313,500.
What is the monthly payment during the initial period?
(1 point)
$1,832.69
$1,496.70
O $1,682.94
$870.83
The interest rate in during the initial period is given from which the
monthly payment is calculated to be $1682.94
Response (approximate value):
The monthly payment during the initial period is $1,682.94What is an ARM and how does it determine the monthly payment?The type of loan Jackie obtains is an Adjustable Rate Mortgage, ARM,
loan, which is a 4/2 ARM
Therefore;
The introductory interest rate of 5% is fixed for the first 4 years, and will
be adjusted every 2 years after the first four years.
[tex]Initial \ monthly \ payment, \ M = \mathbf{\dfrac{P \cdot \left(\dfrac{r}{12} \right) \cdot \left(1+\dfrac{r}{12} \right)^n }{\left(1+\dfrac{r}{12} \right)^n - 1}}[/tex]
Where;
M = The monthly payment during the initial period
P = The amount on loan = $313,500
r = 5% = 0.05
n = 30 × 12 = 360
Which gives;
[tex]M = \dfrac{313500 \times \left(\dfrac{0.05}{12} \right) \cdot \left(1+\dfrac{0.05}{12} \right)^{360} }{\left(1+\dfrac{0.05}{12} \right)^{360} - 1} \approx \mathbf{1682.94}[/tex]The monthly payment during the initial period, M ≈ $1,682.94Learn more about mortgage payment calculations here:

A bag of marbles contains 6 blue marbles and 1 green marble. Mary and Frank will draw a blue marble followed by a green marble, without replacing the first marble. Mary says the probability will be 6/49, and Frank says that the probability will be 1/7. Who is correct? Explain and justify your answer by showing work.
---------------Is correct because___
Answer:
Frank is correct, because (see explanation below)
Step-by-step explanation:
Let's separate into two cases:
Case 1: Blue marble
[tex]\frac{6}{7}[/tex] (There are 6 blues in the bag and 7 marbles in total in the bag, we put the 6 in the numerator because we want a blue marble first.)
Case 2: Green marble
[tex]\frac{1}{6}[/tex] (There is only 1 green in the bag and 6 marbles remaining in the bag, because we already took 1 blue out in Case 1. We put 1 in the numerator because we want the green marbloe only.)
Multiply Case 1 with Case 2 because they are a combination:
[tex]\frac{6}{7} * \frac{1}{6} = \frac{1}{7}[/tex]
Therefore Frank is correct.

Identify the percent of change as an increase or a decrease. Then find the percent of change. Round to the nearest tenth of a percent if necessary.
12 inches to 36 inches
Answer: 200% increase
Step-by-step explanation:
Being an increase from 12inches to 36inches, we will calculate the percentage increase.
%increase = final length -initial length/initial length × 100%
Initial length = 12inches
Final length = 36inches
%increase = 36-12/12 × 100%
%increase = 24/12 × 100%
%increase = 200%
Answer:
200% increase
Step-by-step explanation:
percent change = [(difference between initial and final value) ÷ initial value] x 100
⇒ percent change = [(36 - 12) ÷ 12] x 100 = 200% increase

Let p(x) be any polynomial of degree greater than or equal to one and let 'a' be any real number. If a polynomial p(x) is divided by x - a then the remainder is p(a). Hence by the remainder theorem, 0 is the remainder when x3 + 3x2 + 3x + 1 is divided by x + 1.

Answer:
see below
Step-by-step explanation:
Is there an operator (+, -, x, /) missing between 100 and 15?
Assume the expression is
=b4*10015/3
The order of operations says that multiplications and divisions are done as they occur from left to right.
The number in cell b4 will be multiplied by 10015, then that result will be divided by 3.
If the expression is supposed to be =b4*100*15/3, then the order is
cell b4 is multiplied by 100, then that is multiplied by 15, then THAT is divided by 3.
