A store in Iowa advertises that during their Labor Day sale, everything is 25% off, plus they will pay the sales tax. Mike buys shoes for $80 and socks for $5. Since there will be no tax added, what is the final price for Mike’s purchase?
9514 1404 393
Answer:
$63.75
Step-by-step explanation:
Mike's final price will be 1-25% = 75% of the marked price.
($80 +5)(0.75) = $63.75
The final price for Mike's purchase is $63.75.
How do you convert 1.6 (6repeating) as a fraction?
9514 1404 393
Answer:
5/3
Step-by-step explanation:
In general, you count the number of repeating digits and use that in the following script.
name the number: x = 1.666...multiply by 10 to the power of the number of repeating digits: 10¹x = 16.666...subtract the original number. The repeating digits should cancel. 10¹x -x = 9x = 15.000...divide by the coefficient of the variable: x = 15/9reduce the fraction: x = 5/3 = 1 2/3The improper fraction is 5/3.
__
Additional comment
When the repeat starts at the decimal point, you can create the fraction by dividing the repeating digits by the same number of 9s.
1/7 = 0.142857...(6-digit repeat)
= 142857/999999
When the repeat has a number of digits, reducing the fraction isn't always easy.
__
If the repeat doesn't start at the decimal point, you can use the above script, or scale the fraction according to where it starts.
Example: 0.4333...(1-digit repeat) = 0.4 + (1/10)(0.333...) = 0.4 + (1/10)(3/9) = 4/10 +1/30 = 13/30
__
Any fraction whose denominator includes factors other than 2 or 5 will be a repeating decimal. It can be helpful to memorize the repeating decimals associated with small-integer fractions:
1/3 = 0.3...(1-digit repeat)
1/6 = 0.16...(1-digit repeat)
1/7 = 0.142857...(6-digit repeat)
1/9 = 0.1...(1-digit repeat) -- of course 2/9, 1/3, etc are multiples of this
1/11 = 0.09...(2-digit repeat) -- as with 1/9, multiples of 1/11 are multiples of this.
1/12 = 0.083...(1-digit repeat)
What type of algebraic expression is 4x + 5?
Answer:
4x + 5 is a polynomial as well as a binomial.
Step-by-step explanation:
The expression 4x + 5 has two monomials 4x and 5 and this makes it a binomial. Now, the second thing to keep in mind is, every binomial is also considered a polynomial as well.

Use the Table to evaluate each expression.
x | 1 2 3 4 5 6
f | 6 4 4 1 6 4
g | 5 5 2 1 4 3
a). f(g(1))
b). g(f(1))
c). f(f(1))
d). g(g(1))
e). (gof)(3)
f). (fog)(6)
Explain the concept and show step-by-step solution.
Here we have a problem of composition of functions.
Remember that:
(f ° g)(x) = f( g(x) )
Now we have the table:
x | 1 2 3 4 5 6
f(x) | 6 4 4 1 6 4
g(x) | 5 5 2 1 4 3
Using the table, we want to find:
To read the table, for example for f(5) first you go to the "x" part of the table and find the 5.
Now you go to the f(x) table and see which is the value of f(5), in this case, we can see that f(5) = 6.
a) f(g(1))
First, looking at the table, we can see that:
g(1) = 5
Then:
f(g(1)) = f(5)
Again, looking at the table we can see that f(5) = 6
Then we have:
f(g(1)) = 6
b) g(f(1))
Same approach as before:
f(1) = 6
then g(f(1)) = g(6)
And looking at the table, g(6) = 3
Then: g(f(1)) = 3
c) f(f(1))
f(1) = 6
f(f(1)) = f(6) = 4
f(f(1)) = 4
d) g(g(1))
g(1) = 5
then:
g(g(1)) = g(5) = 4
g(g(1)) = 4
e) (gof)(3)
This is equal to:
(gof)(3) = g(f(3))
we know that f(3) = 4
then:
g(f(3)) = g(4) = 1
(gof)(3) = 1
f) (fog)(6) = f(g(6))
We can see that:
g(6) = 3
then:
f(g(6)) = f(3) = 4
Concluding:
(fog)(6) = 4

When it comes to adding a positive number and a negative number the main point you should focus on is that if its the same sign you have to keep it and add them together. But since they aren't the same signs and they are different signs you have to subtract them and keep the sign of the bigger number which is -5 in this problem.

What shape is always created in graphing the addition of two vectors?
You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).
An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram
Side note: The other diagonal is either u-v or v-u depending on your reference point.

LN = 37MN = 23 EF = 58The required worksheet is attached below :
A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.
Given that :
LM = 22 ; MN = 15
The segment LN is defined as :
LN = LM + MN
LN = 22 + 15
LN = 37
2.)
LN = 54
LN = 54 LM = 31
The line segment, LN equals :
LN = LM + MN
54 = 31 + MN
MN = 54 - 31
MN = 23
3.)
DF = 9x - 39
DE = 47
EF = 3x + 10
The line segment, DF equals ;
DF = DE + EF
9x - 39 = 47 + (3x + 10)
9x - 39 = 47 + 3x + 10
9x - 3x = 47 + 10 + 39
6x = 96
x = 96 / 6
x = 16
Hence,
EF = 3x + 10
EF = 3(16) + 10
EF = 48 + 10
EF = 58

Find the measure of the smaller angle formed by the hands of a clock at the following time.
1:25
The smaller angle formed by the hands of a clock at the following time.
1:25 is 42.5 degrees and 107.5 degrees
What is total angle of a circle?360 degrees
We need to find the angles of clock at 1:25
At 1:25, the hour hand has moved 85 out of 720 possible times from the top of the clock. 85 times 0.5 degrees is 42.5 degrees.
At 1:25, the minute hand has moved 25 out of 60 possible times from the top of the clock. 25 times 6 degrees is 150 degrees.
150 - 42.5 = 107.5 degrees
Therefore the smaller angle formed by the hands of a clock at the time 1:25 is 42.5 degrees and 107.5 degrees
