This is how you would determine the equation and solve the problem:
- First, it is important that you find how much each eraser cost. You do know that 66 erasers cost $6.60. So create an equation.
- The equation would be: 66/6.60
which means each eraser was 10 cents each
- Now you can create a equation that would determine the cost of 333 erasers since you know how much each eraser actually cost. The equation would be:
- .10×333=?
To create that equation all you need to do is multiply the price of the erasers (10 cents) by how many erasers you are buying (333).

E

Which pair of functions are inverses of each other?
A. f( x ) = 6/x − 5 and g ( x ) = x + 5 /6
B. f(x) = 8x – 3 and g ( x ) = x + 3/8
C. f ( x ) = sqr 3 7x and g ( x ) = ( x /7 )3
D. f ( x ) = x /9 + 1 2 g(x) = 9x – 12
The inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.
What is an inverse function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The inverse function of a function f in mathematics is a function that reverses the operation of f. If and only if f is bijective, then the inverse of f exists, and if it exists.
The inverse of the function is given by,
f(x) = 8x – 3 and g ( x ) = x + 3/8
The inverse of the function is calculated by dividing the function by the coefficient of x and reversing the sign of the function.
f(x) = 8x – 3
Divide the function by 8.
f(x) = ( 8x - 3 ) / 8
Reverse the sign of the function.
f(x) = ( 8x + 3 ) / 8
Simplify the function.
f(x) = ( x + 3 / 8 ).
Therefore, the inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.

If a board 8 ¾ ft. long is cut into 7 equal parts, how long is each part?
Answer:
26 5/32 in. or 2 ft
Step-by-step explanation:
Since we are taking into account 1/8in for each saw cut the total length of the 4 pieces of wood will be 3/8in less than the single long piece (3 cuts * 1/8).
Let's first convert the piece of wood to inches:
8 3/4ft = 8.75ft
8.75 ft *(12in./1ft) => 8.75 *12= 105 inches
Now we can subtract the 3/8in that will be lost from making 3 cuts:
105in. - 3/8in. = 104 5/8in.
So the total length of the 4 pieces of wood will be 104 5/8in.
Therefore, each piece will be (104 5/8in)/4 in length.
First let's convert 104 5/8in. to an improper fraction to make it easier to work with:
104 5/8in. = (104*8 + 5)/8in.
=837/8in.
Now we can divide this by 4 to get the length of each piece of wood:
(837/8in.)/4 is the same as (837/8in.)*(1/4)
Multiply numerators together, and multiply the denominators together:
(837/8in.)*(1/4) = 837/32in.
Convert back to a mixed number if needed:
837/32in.= 26 5/32in. or 2ft, 2 5/32in.

Seven out of 14 Apple Computers have specialized movie editing software. Approximately what percent of the Apple computers can be used for editing movies?
Answer:
Approximately 50% of the Apple computers can be used for editing movies.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the percent that represent the 7 computers that have the specialized movie editing software given that there are 14 Apple computers which represents 100%:
14 → 100%
7 → x
x=(7*100)/14=50%
According to this, the answer is that approximately 50% of the Apple computers can be used for editing movies.
Find the binomial distribution for flipping a coin 3 times, where "heads" is a success. P(k successes) = nCk pk(1 – p)n – k P(0 successes) = 3C0(0.5)0(0.5)3
Answer:
0.125, 0.375, 0.375, 0.125
Step-by-step explanation:
For a binomial distribution :
nCk * p^k * (1 – p)^(n – k)
P(0 successes) = 0 head, k = 0
n = 3 = number of flips
P(success) = 0.5
3C0 * 0.5^0 * 0.5^3
1 * 0.5^0 * 0.5^3 = 0.125
P( 1 success) = 1 head, k = 1
n = 3 = number of flips
P(success) = 0.5
3C1 * 0.5^1 * 0.5^2
3 * 0.5^1 * 0.5^2 = 0.375
P(2 successes) = 2 head, k = 2
n = 3 = number of flips
P(success) = 0.5
3C2 * 0.5^2 * 0.5^1
3 * 0.5^2 * 0.5^1 = 0.375
P(3 successes) = 3 head, k = 3
n = 3 = number of flips
P(success) = 0.5
3C3 * 0.5^3 * 0.5^0
1 * 0.5^3 * 0.5^0 = 0.125

0.125, 0.375, 0.375, 0.125

Sofia purchased a new car in 2007 for$34,000. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $16,200 in the year 2014, then what would be the predicted value of the car in the year 2021, to the nearest dollar?
Answer:
$7,718
Step-by-step explanation:
Given that :
Cost of car in 2007 = $34000
Cost of car in 2014 = $16200
Predicted value of car in 2021
Lets obtain the percentage Depreciation (d) :
Worth (A) of car in 2014 = $16200
Time (t) = 2014 - 2007 = 7 years
Initial cost (I) = price in 2007
A = I(1 - d/100)^7
16200 = 34000( 1 - d/100)^7
16200 = 34000(1 - 0.01d)^7
(16200/34000)^1/7= 1 - 0.01d
0.8995 = 1 - 0.01d
0.01d = 1 - 0.8995
d = 0.1005 /0.01
d = 10.05
Value of car in year 2021:
t = 2021 - 2007 = 14 years
A = I(1 - 10.05/100)^14
A = 34000(1 - 0.1005)^14
A = 34000(0.8995)^14
A = 34000 * 0.2269950
A =7717.83100
Approximate worth = $7718

∆GHI is an isosceles triangle with a vertex angle H
If the m∠H=80°, then find the m∠I.
Given :
∆GHI is an isosceles triangle with a vertex angle H.
m∠H=80°
To Find :
The m∠I.
Solution :
Since, H is the vertex angle.
So, m∠I = m∠G = x
We know, by angle sum property of triangle :
m∠I + m∠G + m∠H = 180°
2x + 80° = 180°
x = 50°
Therefore, m∠I = 50° .

Debbie cut a cord into sixths. She used five of the pieces to make necklaces. She used equal lengths of the remaining cord for each of four bracelets. What fraction of the original cord did Debbie use
Answer:
1/24
Step-by-step explanation:
Debbie cut a cord into 6 places and use five pieces to make a necklace.
i.e.
5/6 was used to make a necklace and we have 1/6 remaining cord.
However, the remaining cord was used for each of the four bracelets.
i.e.
(1/6) ÷ 4
(1/6) *(1/4) = 1/24
Thus, the fraction of the original cord that Debbie used to make this bracelets = 1/24

Consider w=sqrrt2/2(cos(225°) + isin(225°)) and z = 1(cos(60°) + isin(60°)). What is w+ z expressed in rectangular form?
Answer:
Option (3)
Step-by-step explanation:
w = [tex]\frac{\sqrt{2}}{2}[\text{cos}(225) + i\text{sin}(225)][/tex]
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -[tex]\frac{\sqrt{2}}{2}[/tex]
sin(225) = sin(180 + 45)
= -sin(45)
= -[tex]\frac{\sqrt{2}}{2}[/tex]
Therefore, w = [tex]\frac{\sqrt{2}}{2}[-\frac{\sqrt{2}}{2}+i(-\frac{\sqrt{2}}{2})][/tex]
= [tex]-\frac{2}{4}(1+i)[/tex]
= [tex]-\frac{1}{2}(1+i)[/tex]
z = 1[cos(60) + i(sin(60)]
= [tex][\frac{1}{2}+i(\frac{\sqrt{3}}{2})[/tex]
= [tex]\frac{1}{2}(1+i\sqrt{3})[/tex]
Now (w + z) = [tex]-\frac{1}{2}(1+i)+\frac{1}{2}(1+i\sqrt{3})[/tex]
= [tex]-\frac{1}{2}-\frac{i}{2}+\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]
= [tex]\frac{(i\sqrt{3}-i)}{2}[/tex]
= [tex]\frac{(\sqrt{3}-1)i}{2}[/tex]
Therefore, Option (3) will be the correct option.
Find the 18th term of the arithmetic sequence whose common difference is d = 2 and whose first term is a, = 3.
Answer:
The 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
Step-by-step explanation:
We know that the arithmetic sequence with a common difference 'd' and the first term 'a₁' is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Given the values
d = 2
a₁ = 3
As we have to determine the 18th term of the arithmetic sequence.
so putting n = 18 in the nth term to determine the 18th term.
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{18}=3+\left(18-1\right)2[/tex]
[tex]=3+17\cdot \:2[/tex]
[tex]=3+34[/tex]
[tex]=37[/tex]
Therefore, the 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
