Answer:
7 is the answer
Explanation:
because if you use a calculator, by doing 10% of 70 which equals to 7 which that is the answer.
Answer:
B: $63
Step-by-step explanation:
You can make an equation: 70(10%)
Which can be simplified into 70(0.1)
70×0.1=7
Since it was discounted, you subtract
$70 - $7 = $63

Brett has a $30 online gift voucher. He plans to buy as many books as he can. The cost of each book is $4. There is also a single shipping charge of $2. How many books can he afford without spending more than his gift voucher amount?
its an inequality eqution, i already know he can spend 30 or less on the boook
answer:
30 > 4x + 2 and 6 books
step-by-step explanation:
read the question and set up the inequalitylet x = number of books he can afford30 > 4x + 2
30 would be on one side since that's the most he can spend4x because each book is $4+ 2 because there is a charge of $230 > 4x + 2
28 > 4x
7 > x
he can afford 6 booksit cannot be 7 because if he does buy 7 books, it would cost more than $30Please help with this! Please don't get it wrong T0T

Your mom deposits $3500 into an account that pays 4.75% annual interest compounded continuously. How many years will it take for the amount of money in the account to reach $15,000? Just enter a numerical answer for the number of years rounded to the hundredth place.
Answer:
About 31 years
Step-by-step explanation:
Given data
Principal= $3500
Rate= 4.75%
Final amount= $15,000
Time=??
The expression for time on compound interest is
Calculate time, solve for t
t = ln(A/P) / r
substitute
Calculate time, solve for t
t = ln(15000/3500) / 0.0475
t= ln(4.2857)/ 0.0475
t= 1.4552/0.0475
t= 30.63 years
Hence it will take about 31 years

if a^3-1/a^3=4 then what is the value of a-1/a ??
Answer:
1 or -0.5±1.9365i
Step-by-step explanation:
We know that [tex]x^{3} - y^{3} = (x-y) ^{3} +3xy(x-y)[/tex]
So plug in x=a and y=1/a, (a-1/a)^3+3*a*1/a*(a-1/a)=4
Let a-1/a=k, k^3+3k=4, k=1 or a complex conjugate -0.5±1.9365i
That's the answer.

number of boys is 5:6. How many boys are in Mary's class?
Solve the following system of equations using substitution.
1)y = 3x - 5
2)5x - 4y = -3
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
[tex]5x - 4y = -3[/tex]
[tex]5x - 4(3x-5) = -3[/tex]
[tex]5x -12x+20=-3[/tex]
[tex]-20[/tex] [tex]-20[/tex]
_______________
[tex]5x-12x=-23[/tex]
[tex]-7x=-23[/tex]
___ ____
[tex]-7[/tex] [tex]-7[/tex]
[tex]x=3.29[/tex] (rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
[tex]y = 3x-5[/tex]
[tex]y = 3(3.29)-5[/tex]
[tex]y = 9.87-5[/tex]
[tex]y = 4.87[/tex]
So, your final answer would be (3.29, 4.87).

Lin is planting a circular garden of tulips. She plans to plant four different colors in equal amounts. The garden will have a diameter of 24 feet.
Answer:
113 square feet
Step-by-step explanation:
Given
[tex]d = 24[/tex] --- diameter
See attachment for complete question
Required
Determine the area of each color
First, we calculate the area of all colors
[tex]Area = \frac{\pi d^2}{4}[/tex]
This gives:
[tex]Area = \frac{22 * 24^2}{7*4}[/tex]
[tex]Area = \frac{12672}{28}[/tex]
[tex]Area = 452.57[/tex]
Since all 4 colors have equal areas, the area of 1 of them is:
[tex]A = \frac{1}{4}Area[/tex]
[tex]A = \frac{1}{4} * 452.57[/tex]
[tex]A = 113.14ft^2[/tex]
[tex]A = 113ft^2[/tex] --- approximated

Answer:
-1 and 4/3
Step-by-step explanation:
Given the quadratic equation;
f(x) = 3x^2-x-4
To get all potential roots, we will equate f(x) = 0
3x^2-x-4 = 0
3x^2-4x+3x-4 = 0
x(3x-4)+1(3x-4) = 0
(x+1)(3x-4) = 0
x+1= 0 and 3x-4 = 0
x = -1 and 3x = 4
x = -1 and x= 4/3
Hence the potential roots are -1 and 4/3
A. f(x) =1/2 (4,000)^x
B. f(x) = 4,000(2)^x
C. f(x) = 2,000 (1/2)^x
D. f(x) = 4,000 (1/2)^x

(financial math) Elementary and Secondary Education is paid mostly from:
O Corporate Taxes
О Defense Taxes
O State Taxes
O Federal Taxes
State taxes.
According to Urban dot org, school funding is a blend of federal, state, and local dollars.
State taxes are more likely to be correct due to education being the state's responsibility.
If this is incorrect, please, don't refrain to tell me. Thank you.

Write the number 510 in scientific notation.
Answer:
500+10+0
Step-by-step explanation:
Answer:
5.1 x 102 in scientific notation
Step-by-step explanation:
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease. Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10bStep 1
step1: To find a, take the number and move a decimal place to the right one position.
Original Number: 510
New Number: 5.10
step 2: Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 1 0
Decimal Count: 1 2
Step 3: Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.1 (Please notice any zeroes on the end have been removed)
b = 2
Now the whole thing:
5.1 x 102
Step 4:
Check your work:
102 = 100 x 5.1 = 510
A line contains the points (-6, -4) and (0, 4). What is the equation of this line in slope-intercept form? A. B. C. y = x – 4 D. y = x + 4
Answer:
y = 4/3 x + 4
Step-by-step explanation:
The general form of the equation of a line is given as
y = mx + c where m is the slope and c is the intercept on the y axis
where the slope m = (y2 - y1)/(x2 - x1)
Hence given the points (-6, -4) and (0, 4)
m = (4 --4) / (0 --6)
= (4+4)/(0+6)
= 8/6
= 4/3
For a line with given points (x1, y1), the equation is given as
y-y1 = m(x-x1)
Hence the equation of this line in slope-intercept form
y - -4 = 4/3(x --6)
y + 4 = 4/3(x + 6)
3y + 12 = 4x + 24
3y = 4x + 24 - 12
3y = 4x + 12
y = 4/3 x + 4
For a line with given points (x2, y2), the equation is given as
y-y2 = m(x-x2)
Hence the equation of this line in slope-intercept form
y-4 = 4/3(x - 0)
multiply through by 3
3y - 12 = 4x
3y = 4x + 12
y = 4/3 x + 4

One of the limitations of using the range is that it is a _____________ measure of variability. It is ______________ susceptible to ______________. It is used mostly with ______________ or ordinal data.
Answer:
One of the limitations of using the range is that it is a simple but poor measure of variability. It is very susceptible to poor representation of data spread. It is used mostly with ordered data or ordinal data.
Step-by-step explanation:
The measure of the range of a set of given data can be established once the difference between the highest and lowest values is known.
The range is simple to use but only considers the smallest and largest data elements in the set without considering the middle values and other values that could influence results if the data spread is to be considered.
Ordinal data aren't numerical data. Examples include Time of day such as morning, noon, night.
