537.95 x 9.5% = ?
Step 2
Convert the % to a decimal:
9.5% to 0.095
Step 3
Rewrite the problem with decimal replacing the percentage.
Now the problem looks like this:
537.95 x 0.095 = 51.11
This problem gives the amount of the tax.
Step 4
Add the original price with the tax amount:

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.
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

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.

Inverse for f(x)=1/2x+3
Answer: [tex]f^{-1}(x)=2x-6[/tex]
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[tex]y=\frac{1}{2}x+3[/tex] [switch x and y]
[tex]x=\frac{1}{2}y+3[/tex] [subtract both sides by 3]
[tex]x-3=\frac{1}{2} y[/tex] [multiply both sides by 2]
[tex]y=2x-6[/tex]
Now, we know that [tex]f^{-1}(x)=2x-6[/tex].
A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

For which other positive integers a, less than 11, will the number (a^n) + (a^n+1) + (a^n+2) + (a^n+3) + (a^n+4) always be divisible?
Pls, Answer with the entire explanation.
If the number is supposed to be
[tex]a^n + a^{n+1} + a^{n+2} + a^{n+3} + a^{n+4}[/tex]
then it can be factorized as
[tex]a^n \left(1 + a + a^2 + a^3 + a^4\right)[/tex]
but there's not much to say about divisibility here without any more information about a.
If you meant
[tex]a^n + (a^n+1) + (a^n+2) + (a^n+3) + (a^n+4)[/tex]
simplifying gives
[tex]5a^n + 10 = 5 (a^n+2)[/tex]
which is clearly divisible by 5.

The answers to the segment addition problems are :
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

Use the Table to evaluate each expression.

f | 6 4 4 1 6 4

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
