You buy a watch for $60. There is a 6% sales tax. What is your total cost for the
watch?
Answer:
$63.3
Step-by-step explanation:
You buy a 60 dollar watch.
60
There is a 6 percent tax. When adding tax, multiply the 6 percent by the original amount.
60 x 0.06
3.6
Add the tax to the original amount.
60 + 3.6 = 63.3
So, your total cost is 63.3 dollars.
Answer:
$63.60
Step-by-step explanation:
The area of a square is 117 square meters which best represents the length of a side.
The best representation for the length of a side of the square is 10.82 meters.
Given that the area of the square is 117 square meters.
Let's denote the length of the side of the square as "s."
The formula for area of square
= s²
Substituting the value of area of square 117 square meter back to the formula
117 = s²
Take the square root of both sides:
s = √(117)
s ≈ 10.82 meters
So, the length of a side of the square is 10.82 meters.

Gracie can iron 3 shirts in 13 minutes. At this rate, how long will it take her to iron 10 shirts? Which proportion shows how to solve the problem?
Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts

Consider the segment AB with A positioned at (6,2). The midpoint of AB, M is located at (5, -3). What are the coordinates of point B? * O (7,7) O (4,-8) O (5.5, -0.5) O (4,5)
Answer:
I didn't "do the math" yet at all, but draw it out on an X,Y axis... Thinking about it logically... If point A is in the upper right quadrant of the axis, because both X and Y coordinates are positive numbers, so you go right on the horizontal axis and up on the vertical axis... Then the midpoint is in the lower right quadrant of the due to the X coordinate being a positive, thus you go right on the horizontal axis, but the Y coordinate is a negative, so you go down vertically... So point B cannot be above both the midpoint or point A, ruling out (7,7) and (4,5) as both Y coordinates of those answers (7 or 5) are higher than point A's Y coordinate of 2... B would have to be below point A because the midpoint is below point A with a Y coordinate of -3... So this leaves either option (5,-0.5) or option (4,-8)... However.... While (5,-0.5) has a lower Y coordinate than point A with -0.5, its Y coordinate is above the Y coordinate of the midpoint as well, since -0.5 is above -3... So this doesn't jive as point B cannot be between point A and the midpoint to point B... This logically leaves (4,-8) left to be the answer... And if you drew on an X,Y axis the coordinates (6,2) as well as (5,-3) and (4,-8), then connect the dots, you'd find (5,-3) sits about half ways between (6,2) and (4,-8)...
So (4,-8) is probably the answer...
The best way to come to this conclusion mathematically is finding the slope (rise over run) of point A and the midpoint between point A and point B, then continuing the slope down, etc... But this particular question with the multiple choice answers ruled all but 1 answer out...
To find the slope you take rise over run, which is the Y of the 2nd coordinate minus the Y of the 1st coordinate, divided by (or over) the X of the 2nd coordinate minus the X of the 1st coordinate....
IE: ( Y2 - Y1 ) / ( X2 - X1 ) = Rise / Run
So.... The 2nd coordinate's Y value is -3, and the 1st coordinate's Y value is 2... Subtract 2 from -3, and you get -5...
Then the 2nd coordinate's X value is 5, and the first coordinate's X value is 6... Subtract 6 from 5, and you get -1...
Divide -5 over -1, which equals the same as 5 over 1... The rise is 5, the run is 1, the slope is 5 steps vertically for every 1 step horizontally...
Or visually... ( -3 - 2 ) / ( 5 - 6 ) which is -5 / -1... Since both sides are negative, that's the same as 5 / 1... which is 5 vertical steps (rise) for every 1 horizontal step (run), or a slope of 5...
So add the slope rise of 5 to the Y coordinate of the midpoint, -3, and you get 2, which is the Y coordinate of point A... And add slope run of 1 to the midpoint X coordinate, 5, and you get 6, the X coordinate of point A... Now subtract the slope rise of 5 from the midpoint, -3, and you get -8... So that tells you that point B has to have a Y coordinate of -8.... And now subtract the slope run of 1 from the midpoint X coordinate, 5, and you get 4... The X coordinate of point B... Giving you a point B coordinate of (4,-8)...

maria brought a blouse on sale for 20% off. the sale price was $21.76. what was the original price? round to the nearest hundredth.
Answer: $27.20
Step-by-step explanation:
She bought a blouse for 20% off so it means that she paid 80% of the original price.We can then set up the equation
80% of x = 21.76 where x is the original price so solve for x
0.8x = 21.76
x = 27.20
Which means the original price is $27.20

What is 20-12x=8-10x
Answer: x= 6
Step-by-step explanation:
20 -12x = 8 - 10x Add 12x to both sides
+12 +12
20 = 8 + 2x subtract 8 from both sides
-8 -8
12 = 2x Divide both sides by 2
x = 6
Answer:
x=6
Step-by-step explanation:
20-12x=8-10x
Add 12x to each side
20-12x+12x=8-10x+12x
20 = 8 +2x
Subtract 8 from each side
20-8 = 8+2x-8
12 = 2x
Divide by 2

Answer:

Step-by-step explanation:
Given
2(2x - 1) = 3(x - 6) ← distribute parenthesis on both sides
4x - 2 = 3x - 18 ( subtract 3x from both sides )
x - 2 = - 18 ( add 2 to both sides )
x = - 16
-------------------------------------------------------------------
Given
4(5 - 7b)- 4 = - 3(1 + 3b) ← distribute parenthesis on both sides )
20 - 28b - 4 = - 3 - 9b , that is
16 - 28b = - 3 - 9b ( add 9b to both sides )
16 - 19b = - 3 ( subtract 16 from both sides )
- 19b = - 19 ( divide both sides by - 19 )
b = 1

Determine whether the dilation from Figure ABC to Figure A'B'C' is a reduction or enlargement Then find its scale factor.
Answer:
This dilation from Figure ABC to Figure A'B'C' is a reduction, with a scale factor of 1/3.
Step-by-step explanation:
The points for Figure ABC are
A =(3,3)
B =(6,3)
C =(6,-3)
The points of Figure A'B'C' are
A' =(1,1)
B' =(2,1)
C' =(2,-1)
To get from (3,3) to (1,1) we have to multiply by 1/3, (6,3) to (2,1) multiply by 1/3, and so on.
