The rectangular base of a 3-D printer East 4.5' by 3' in the Keogh's drawing the base of the printer is 3" by 2" of nicaea in larger drawing to 3 times its size would foot the scale of her events draw
Answer:
[tex]Scale = 1.5[/tex]
Step-by-step explanation:
Given
[tex]Printer = (4.5',3')[/tex]
[tex]Keogh = (3',2')[/tex]
Required
Determine the scale
This is calculated as:
[tex]Scale = \frac{Original}{Actual}[/tex]
[tex]Scale = \frac{(4.5,3)}{(3,2)}[/tex]
Factorize the numerator
[tex]Scale = \frac{1.5 * (3,2)}{(3,2)}[/tex]
Scale = \frac{1.5 * (3,2)}{(3,2)}[tex]Scale = 1.5 * \frac{(3,2)}{(3,2)}[/tex]
[tex]Scale = 1.5 * 1[/tex]
[tex]Scale = 1.5[/tex]

Marcia is at a store with a 20% off sale. She also has a coupon for an additional 10% off the sale price.
Prove or disprove the following statement: A 20% discount on the original price of an item, followed by the use of a 10% off coupon, results in a total discount of 30%.
I wil brainly anyone who answers this right with explination
Answer:
False
Step-by-step explanation:
I will use an example here:
Original price of a pc is $799
you use your 20% off coupon which will bring it down:
799 decrease 20% =
799 × (1 - 20%) = 799 × (1 - 0.2) = 639.2
then you use your 10% off coupon:
639.2 decrease 10% =
639.2 × (1 - 10%) = 639.2 × (1 - 0.1) = 575.28
our final price doing them separately is $575.28
while doing it in one step by subtracting 30%:
799 decrease 30% =
799 × (1 - 30%) = 799 × (1 - 0.3) = 559.3
our price by doing it with a 30% discount is $559.30

What is 16.281 rounded to the nearest whole number?
Answer:
16
Step-by-step explanation:
The round-off to the number 16.281 will be 16.
What is rounding off the number?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
The given number is 16.281. The round-off to the number will be 16 because the decimal value is less than 5.

Noah wrote that 6+6 =12. Then he wrote that
6+6 -n =12 - n. Are his equations balanced? Explain.
Answer:
Hs equations are balancedStep-by-step explanation:
To check whether both equations are balanced, we will simplify
6+6 -n =12 - n
Add n to both sides of the equation using additive property
6+6-n+n = 12-n+n
6+6 +0 = 12+0
6+6 = 12 (This gives the other equation)
Since they are both equal, this shows that the equations are balanced
