Answer:
90% of paperclips did not get used.
Step-by-step explanation:
Your office manager used 45 paperclips for handouts at his presentation from the 450 paperclips available in the stock room.
We have to calculate the percentage of the original number of paperclips did not get used.
number of paperclips did not get used = 450 - 45 = 405
the percentage of 405 out of 450 = [tex]\frac{405}{450}[/tex] × 100
= 0.9 × 100
= 90%
Therefore, 90% of paperclips did not get used.

A. y=x^2-x+4
B. 2/x
C. x-3^3/x^2

Your monthly living expenses are $1500 on an income of $1,650 per month. Your goal is to have an emergency fund of 4 times your monthly living expenses. Your emergency fund savings account has $2,400 and you put the remainder of your monthly income into the emergency fund each month. How much more money would you have to save each month to complete your emergency fund in 12 months?
a.
$300 per month
b.
$150 per month
c.
$75 per month
d.
$60 per month
Answer:
b. $150 per month
Step-by-step explanation:
To begin solving this let us calculate the amount of our Goal and how much we are saving per month. Our goal is to save up 4 times the amount of our monthly expenses. So we multiply our monthly expenses by 4 like so,
[tex]1,650 - 1,500 = 150[/tex] savings per month
[tex]1,500 * 4 = 6,000 goal[/tex]
We are currently saving $150 per month. Now that we know our goal is $6000. Lets calculate how far off we are with what we already have in our savings by subtracting our goal from our current savings.
[tex]6,000-2,400 = 3,600[/tex]
We need to save up $3,600 in 12 months which would be
[tex]\frac{3600}{12}=300[/tex]
Therefore we need to put $300 a month into our savings account to reach that goal in 12 months. Since we already put $150, this means we need to make an additional $150 a month to reach our goal in 12 months.

Answer: 4 slices
Step-by-step explanation:

FlybynightSavings.com is offering a savings account that pays 28% compounded continuously. How much interest would a deposit of $3,000 earn over 5 years? (Round your answer to the nearest cent.)
The continuous compound interest of a $3,000 deposit with an annual rate of 28% over 5 years would be approximately $9,156.58.
Explanation:The question pertains to continuous compound interest, which is represented by the formula A = P imes ert, where A is the final amount, P the principal amount, r is the interest rate (written in decimal), t is the time in years, and e is the base of natural logarithms.
Given that P=$3,000, r=28/100=0.28 and t=5 years, you would substitute these values into the formula to get A = $3000 imes e(0.28 imes 5).
Computing this, gives:
A = $3000 imes e1.4 = $3000 imes 4.0552 (approximately).
So, A = $12156.58 (rounded to the nearest cent).
The interest earned would therefore be: A - P.
Thus, the interest would be $12156.58 - $3000 = $9156.58.

To find out how much interest a deposit of $3,000 would earn over 5 years with an interest rate of 28% compounded continuously, we would need to use the formula for continuously compounded interest, which is A = P*e^(rt).
Here,
A represents the total amount of money accumulated after n years including interest,
P is the principal amount, which is the initial amount of money,
r refers to the annual interest rate expressed in decimal form, and
t is the time the money is invested for in years.
Given in the problem we have P = $3000, r = 28% = 0.28, and t = 5 years.
Substituting these values into the formula we get:
A = 3000 * e^(0.28*5)
Solving this would yield the total amount accumulated after 5 years.
Next, we would need to calculate the accrued interest. This is done by subtracting the principal amount (the initial deposit) from the total amount.
So, the interest earned would be calculated as:
Interest Earned = Total Amount - Initial Deposit.
The numerical calculation of these formulas provides us the result that the total amount after 5 years would be approximately $12,165.60 and the interest earned would be approximately $9,165.60.
Thus, a deposit of $3000, with an interest rate of 28% compounded continuously over 5 years, would earn you interest of about $9,165.60.
This is of course rounded to the nearest cent as required.

State if the three numbers can be the measures of the sides of a triangle
In mathematics, specifically geometry, we can determine whether three given numbers can be the sides of a triangle by applying the Pythagorean theorem (a² + b² = c²). For instance, the sides with lengths 3, 4, and 5 can form a right triangle because 3² + 4² equals 5².
Explanation:
The subject question is about determining whether three given numbers can form the sides of a triangle. This is an area of Mathematics that deals with geometry, specifically triangles.
The knowledge of Pythagorean theorem which states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides, often written as a² + b² = c², helps to verify if the three given numbers are the lengths of the sides of a triangle.For example, if given lengths are 3, 4, and 5. We square each side (9, 16, and 25 respectively) and then, according to Pythagorean Theorem, add together the squares of the two smaller sides to see if they equal the square of the largest side (9 + 16 = 25), the numbers do follow the rule of the Pythagorean Theorem, hence they could form the sides of a right triangle.Learn more about Pythagorean theorem here:

A regular box of cereal holds 14 ounces. If an economy box is made by doubling all the dimensions of the regular-sized box, how many ounces will the economy box hold? ...?
Answer: The economy box will hold 112 ounces.
Step-by-step explanation:
Since we have given that
A regular box of cereal holds = 14 ounces
Let the dimesion of regular box be x .
so, Volume of regular box is given by
[tex]x\times x\times x =x^3= 14[/tex]
According to question, if the box is made by doubling all the dimensions of the regular sized box.
So, volume becomes
[tex]2x\times 2x\times 2x\\\\=2^3\times x^3\\\\=8\times x^3\\\\=8\times 14\\\\=112\ ounces[/tex]
Hence, The economy box will hold 112 ounces.

Use the following statements to write a compound statement for the conjunction or disjunction. Then find its truth value.
p: An isosceles triangle has two congruent sides.
q: A right angle measures 90°.
r: Four points are always coplanar.
s: A decagon has 12 sides.
the following is a conjunction
p∧q: An isosceles triangle has two congruent sides and a right angle measures 90°.
this statement is true because both p and q are true.
The following is a disjunction :
r∨s: Four points are always coplanar or A decagon has 12 sides.
this statement is false besause both statemens r and s are false: You could have four points in the three dimensional space that are not in one plane, and a decagon is a figure with 10 sides (not 12).

They are not similar because Segment BR to segment DB is 1:5 and Segment KE to segment YK is 1:2.
They are not similar because Segment BR to segment DB is 1:2 and Segment KE to segment YK is 1:5.
They are similar because Segment BR to segment DB is 1:5 and Segment KE to segment YK is 1:5.
