A box contains 5 reams of paper. How could you estimate the thickness of 2 sheets of paper? One ream of paper is 500 sheets.
Please provide deep explanation so i can learn and understand
The estimated thickness of 2 sheets of paper, given the parameters, is 0.0216 cm.
What is the thickness of a sheet of paper?The thickness of a sheet of paper can be measured using a screw gauge or vernier caliper.
If the thickness of a ream of paper, which contains 500 sheets, is given, a sheet will be x/500 thick.
The thickness of 2 sheets of paper will be the thickness of a sheet multiplied by 2.
Data and Calculations:
Number of reams of paper in a box = 5 reams
1 ream = 500 sheets
500 sheets = 5.4 cm thick
The thickness of 2 sheets of paper = 0.0216 cm {5.4cm x 2/500)}
Thus, the estimated thickness of 2 sheets of paper, given the parameters, is 0.0216 cm.

Alice placed $1,900 in a savings account which earns 2.2% interest, compounded every year. How much will she have in the account after 5 years.
She will have $2118 in her account after five years
How to determine the amount in five years?The given parameters about the compound interest are
Principal Amount, P = $1,900
Interest Rate, R = 2.2%
Time, t = 5
Compound interests are different from simple interest, and they are calculated using the following compound interest formula
CI = P(1 + R)^t - P
To calculate the amount, we have:
A = P + CI
So, the equation becomes
A = P + P(1 + R)^t - P
Evaluate the like terms
A = P(1 + R)^t
Substitute the known values in the above equation
A = 1900 * (1 + 2.2%)^5
Express 2.2% as decimal
A = 1900 * (1 + 0.022)^5
Evaluate the sum
A = 1900 * (1.022)^5
Evaluate the exponent
A = 1900 * 1.11495
Evaluate the product
A = 2118
Hence, she will have $2118 in her account after five years

A home gardener estimates that 18 apple trees will produce an average yield of 80 apples per tree. But because of the size of the garden, for each additional tree planted, the yield will decrease by four apples per tree. How many trees should be planted to maximize the total
19 trees should be planted to maximize the total
How many trees should be planted to maximize the totalFrom the question, we have the following parameters:
Number of apples, x = 18
Yield, f(x) = 80 per tree
When the number of apple trees is increased (say by x).
We have:
Trees = 18 + x
The yield decreases by four apples per tree.
So, we have
Yield = 80 - 4x
So, the profit function is
P(x) = Apples * Yield
This gives
P(x) = (18 + x) *(80 - 4x)
Expand the bracket
P(x) = 1440 - 72x + 80x - 4x^2
Differentiate the function
P'(x) = 0 - 72 + 80 - 8x
Evaluate the like terms
P'(x) = 8 - 8x
Set P'(x) to 0
8 - 8x = 0
Divide through by 8
1 - x = 0
Solve for x
x = 1
Recall that:
Trees = 18 + x
So, we have
Trees = 18 + 1
Evaluate
Trees = 19
Hence, 19 trees should be planted to maximize the total

Two jets leave an air base at the same time and travel in opposite directions. One jet travels 80 mi/h faster than the other. If the two jets are 11392 miles apart after 8 hours, what is the rate of each jet
The rate of the slower jet is 672 miles per hour.
The rate of the slower jet is 752 miles per hour.
How to find the rate of the jets?Two jets leave an air base at the same time and travel in opposite directions.
One jet travels 80 mi/h faster than the other.
let
x = rate of the slower jet
faster jet = 80 + x
Therefore,
rate = distance / time
The two jets are 11392 miles apart.
(80 + x)8 + 8x = 11392
640 + 8x + 8x = 11392
640 + 16x = 11392
16x = 11392 - 640
16x = 10752
divide both sides by 16
x = 10752 / 16
x = 672 miles per hour
rate of the faster jet = 80 + 672 = 752 miles per hour

One number is 6 more than another. The difference between their squares is 204. What are the numbers?
Answer: 20 and 14
Step-by-step explanation:
Using a little guess and check, we can figure out that the numbers are 6 apart and the difference between their squares is 204.
[tex]20^2 = 400\\14^2=196[/tex]
[tex]20^2-14^2 = 204[/tex]
A trick to doing this is to start with a number that is easily squared like 10 or 20 and see if the difference between their numbers is larger or smaller and change your numbers based on them.
Hope this helped :)
Answer:
14 and 20
Step-by-step explanation:
Let x and y be two numbers where x < y.
We are given :
y - x = 6
y² - x² = 204
Then
y - x = 6
(y - x)(y + x) = 204
Then
y - x = 6
6 × (y + x) = 204
then
y - x = 6 (Equation 1)
y + x = 34 (Equation 2)
Then
(Equation 1) + (Equation 2) ⇒ 2y = 40 ⇒ y = 20
Now ,we substitute y by 20 in equation 1 :
y - x = 6
⇔ 20 - x = 6
⇔ 20 - 6 = x
⇔ x = 14
Is f(x)= [tex]\sqrt{5-x^{2} }[/tex] a one to one function?
Answer:
No, it is not a one-to-one function.
Step-by-step explanation:
A one-to-one function means a value of y will only exist one value of x. This means that a value of y will only have one value of x.
An example of one-to-one function is an odd-degree polynomial such as linear function.
An example of non one-to-one function is a parabola since a value of y exists two values of x.
From the question, this function represents a graph of half circle with radius equal to [tex]\displaystyle{\sqrt{5}}[/tex]. (The graph has been attached below for visual reference.)
There's also a way to determine whether if a function is one-to-one or not. This can be done by drawing a horizontal line.
If a horizontal line and a graph have one common point then it's a one-to-one functionOtherwise (having more than one common points), a function is not a one-to-one.From the graph and a horizontal line, both have two common points. Therefore, the function is not a one-to-one function.

Answer:
m∠RQS = 109°
Step-by-step explanation:
Angles on a straight line sum to 180°.
Therefore:
⇒ m∠RQS + m∠SQT = 180°
⇒ (15x + 4) + (10x + 1) = 180
⇒ 15x + 4 + 10x + 1 = 180
⇒ 15x + 10x + 4 + 1 = 180
⇒ 25x + 5 = 180
⇒ 25x + 5 - 5 = 180 - 5
⇒ 25x = 175
⇒ 25x ÷ 25 = 175 ÷ 25
⇒ x = 7
Now that we have found the value of x, substitute this into the expression for m∠RQS:
⇒ m∠RQS = 15(7) + 4

2/3 is 400% of 1/6
0.2 is 12.5% of 1 3/5
Calculating PercentagesFrom the question, we are to determine what percent of 1/6 is 2/3
Let the value be x
Thus,
We can write that
2/3 is x% of 1/6
This means
2/3 = x/100 × 1/6
Now, solve for x
2/3 = x/100 × 1/6
2/3 = x/600
x = (2×600)/3
x = 400
Hence, 2/3 is 400% of 1/6
We are to determine what percent of 1 3/5 is 0.2
Let the value be y
That is,
0.2 is y% of 1 3/5
This can be written as
0.2 = y% × 1.6
0.2 = y/100 × 1.6
Now, solve for y
0.2 = y/100 × 1.6
0.2 = 1.6y/100
1.6y = 0.2 × 100
1.6y = 20

The figure shows a cylinder of diameter 12cm and height = 15cm. A hole in the shape of cone is bored into one of its end. If the cone has diameter equal to half of the diameter of the cylinder. find the volume of the remaining solid.
Answer:
[tex]\bold{495\pi} \approx \bold{1555.088 cm^3}[/tex]
Step-by-step explanation:
There was no figure but the question is clear
Volume of a cylinder is given by the formula [tex]\bold{\pi r^2h}\\[/tex]
where r is radius of base of cylinder, h is the height
Volume of a cone is given by [tex]\bold{\frac{1}{3} \pi r^2 h}[/tex]
where r is the radius of base of cone, h is the height
The radius of the cylinder = [tex]\frac{1}{2}[/tex](diameter) = [tex]\frac{1}{2}[/tex](12) = 6cm
Height of cylinder = 15cm
Volume of cylinder [tex]V_{cyl} = \pi (6)^2 15 = \pi (36)15 = \bold{540\pi}[/tex]
Radius of cone = [tex]\frac{1}{2}[/tex] (radius of cylinder) = [tex]\frac{1}{2}[/tex](6) = 3 cm
Height of cone same as height of cylinder = 15cm
Volume of cone, [tex]V_{cone} = \frac{1}{3}\pi r^2 h = \frac{1}{3}\pi (3)^2 15 = \frac{1}{3}(9)15\pi = \bold{45\pi}\\[/tex]
Difference is the volume of the remaining solid
[tex]V_{cyl} - V_{cone} = 540\pi - 45\pi = \bold{495\pi} \approx \bold{1555.088 cm^3}[/tex]
