Step-by-step explanation:
Answer:
40.5 square inches
Step-by-step explanation:
Rectangle consists of two identical squares.
So, if the sides of square = x,
Then, Width of rectangle = x &
Length of rectangle = x +x = 2x
Perimeter of rectangle = 27 inches
2*(length + width) = 27
2*( 2x + x) = 27 {Combine like terms]
2* 3x = 27
6x= 27 {Divide both sides by 6}
x = 27/6
x = 4.5
Width = x = 4.5 inches
Length = 2x = 2*4.5 = 9 inches
Area of rectangle = length *width
= 4.5 *9
= 40.5 square inches
Answer:
<u>The original cost of the printer before adding the tax was $ 173.98</u>
Step-by-step explanation:
Total cost of the color printer, including tax = $ 186.16
Tax rate = 7%
Original cost of the printer, before tax = x
For answering the question, let's use the Rule of Three Simple, this way:
Percentage Value
107% 186.16
100% x
x * 107 = 186.16 * 100
107x = 18,616
x = 18,616/107
x = 173.98
<u>The original cost of the printer before adding the tax was $ 173.98</u>
1) 3n+1=16-2n
- add 2n to both sides
- you should now be left with 5n+1=16
(remember the 2n gets canceled out)
- subtract 1 from both sides
- you should now be left with 5n=15
- now you divide by 5 to get n by itself
- 15 divided by 5 is 3
- n=3
2) substitute n with 3 in to the original equation
- so 3n+1=16-2n now becomes 3(5)+1=16-2(3)
- you should get 10 for both so 10=10
3) according to the segment addition postualte , XR + YR = XY.
- add 10+10 which stands for the lengths of XR and YR
Answer - XY = 20
Answer:
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.
