Answer:
no solution
Step-by-step explanation:
|f-6| = |f+8|
solve absolute values
f-6 = f+8
add 6 to 8
f = f+14
subtract f from f
0=14
not true; no solution

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over time. A new van used in your delivery business has a taxable value of $22,000. The tax code allows you to depreciate this van by $1900 per year. Find a formula that gives the taxable value T, in dollars, of the van after n years of depreciation.
Answer: T = 22,000 - 1,900n
Step-by-step explanation:
Taxable value is $22,000
The tax code allows for the depreciation of this van by $1,900 per year.
After n years therefore the total depreciation is;
= 1,900 * n
This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.
Formula is therefore;
T = 22,000 - 1,900n
Which of the following is a true statement?
a. To square a number, multiply the number
by 2.
b. The inverse of squaring a number is to
divide the number by 2.
c. To square a number, multiply the number
by itself.
d. A perfect square is a number who’s
square root is an even number.
Answer: The answer is c. To square a number is to divide the number by 2.
Step-by-step explanation:
Solve −5x = 30 a.) 6 b.) -6 c.) 25 d.) 35
Evaluate the expression when c=-6.
c? +6c+5
Answer: -31
Step-by-step explanation: 1.) Plug in -6 for c
2.) equation will then be: 6(-6)+5
3.) use PEMDAS: multiply first then addition
4.) 6(-6) equals -36
5.) add -36+5 which equal -31
Therefore your answer should be -31
Simplify the expression. Write the answer with positive exponents only. Assume the variable represents a nonzero real number.
Answer:
[tex]\frac{1}{w^{29}}[/tex]
Step-by-step explanation:
The given expression is [tex]\frac{w^{-7}(w^{-9})^2}{w^4}[/tex].
Since, [tex]w^{-7}=\frac{1}{w^7}[/tex]
And [tex]w^{9}=\frac{1}{w^9}[/tex]
Expression will become,
[tex]\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}[/tex]
[tex]=\frac{\frac{1}{w^7\times w^{18}}}{w^4}[/tex]
[tex]=\frac{\frac{1}{w^{(7+18)}}}{w^4}[/tex]
[tex]=\frac{1}{w^{25}}\times \frac{1}{w^4}[/tex]
[tex]=\frac{1}{w^{25}\times w^4}[/tex]
[tex]=\frac{1}{w^{29}}[/tex]
Therefore, Simplified form of the given expression will be [tex]\frac{1}{w^{29}}[/tex].
A carpenter sands of a dresser in hour. At this rate, how long does it take the
carpenter to sand 1 dresser?
o hour
o hour
O 1 hours
O 23 hours
Question:
A carpenter sands 1/2 of a dresser in 3/4 hour. At this rate, how long does it take the carpenter to sand 1 dresser?
Answer:
[tex]1\ dresser = \frac{3}{2} hour[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]
Required
How long will it take to sand 1 dresser
[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]
Multiply both sides by 2
[tex]2 * \frac{1}{2} dresser = \frac{3}{4} hour * 2[/tex]
[tex]1\ dresser = \frac{3}{4} hour * 2[/tex]
[tex]1\ dresser = \frac{3}{2} hour[/tex]
Hence;
It'll take 3/2 hour to sand 1 dresser

A rope 5 meters long was cut into 7 equal parts. What is the length of each part?
Answer:
5/7 meters
Step-by-step explanation:
Take the 5 meters and divide into 7 parts
5/7 = 5/7 meters
To find the length of each part, we can divide.
5 / 7 = 0.714...
We can just keep it as a fraction.
The answer is 5/7m

Determine whether the equation is always, sometimes, or never true.
2/3 x + 4 = 2x
Answer:
Always true
Step-by-step explanation:
Given
[tex]\frac{2}{3}x + 4 = 2x[/tex]
Required
Determine its type of solution
[tex]\frac{2}{3}x + 4 = 2x[/tex]
Collect Like Terms
[tex]2x - \frac{2}{3}x = 4[/tex]
Take LCM
[tex]\frac{6x - 2x}{3} = 4[/tex]
[tex]\frac{4x}{3} = 4[/tex]
Multiply both sides by [tex]\frac{3}{4}[/tex]
[tex]\frac{4x}{3} * \frac{3}{4}= 4 * \frac{3}{4}[/tex]
[tex]x = 4 * \frac{3}{4}[/tex]
[tex]x = 3[/tex]
Hence, the equation is always true for x = 3

A chocolate company makes chocolate malt balls that have a radius of 0.34
inches. The carton they are to be packed in is approximately a rectangular prism with
dimensions 1.5 inches by 2.5 inches by 6 inches. How many malt balls will fit in the
carton
Answer:
Approximately 141 malt ballsStep-by-step explanation:
this problem is on the mensuration of solids shapes.
first we need to calculate the volume of the rectangular prism
volume of prsim= l*b*h
given that
length= 1.5 in
breath=2.5 in
hieght= 6 in
volume= 1.5*2.5*6
volume=22.5 in^3
secondly we then calculate the volume of a malt ball
given that
raduis r= 0.34
volume of sphere = 4/3πr^3
volume of sphere = 4/3*3.124*(0.34)^3
volume of sphere = 1.33*3.142*0.039
volume of sphere = 0.16 in^3
now we can calculate the amount of sphere that can fit into the prism as
= volume of prism/volume of sphere
= 22.5/0.16
=140.6
approximately 141 malt balls

The sum of all of the exterior angles of an octagon is:
Answer:
1080°
Step-by-step explanation:
sum = 180 ( n - 2)
note that octagon has 8 sides
therefore
sum = 180 ( 8 - 2)
sum = 1080°
Answer:
c. 1080
Step-by-step explanation:
= 180 x ( 8 - 2)
= 1080
What are the coordinates of G, H, and I after a rotation about (0,0) by 90 degrees clockwise? Thank you.
Answer:
Ok, when we have a point (x, y) and we do a rotation of 90° the new points will actually depend on the quadrant where we are, but it will always change the order to (y, x) but this does not end here, because depending on the quadrant where the point ends, the signs will change as follows.
1st quad (+y, +x)
2nd quad (-y, +x)
3rd quad (-y, -x)
4th quad (+y, -x)
So if we are in the second quadrant, the transformed point will be in the first quadrant
Now, we have that the points G and H are:
G = (-1, 3)
This point is in the second quadrant, so it moves to the first quadrant (where bot values must be positive).
The new point will be:
G´ = (3, 1)
And the other point is:
H = (-4, 0)
It also rotates to the first quadrant, so the new point will be:
H' = (0, 4)
Answer:
Because the person above already explained I’ll just give the answers.
Step-by-step explanation:
G = (-1,3) H = (-4,0) I = (3,-2)
