Yes it’s a rectangle because the diagonals bisect each other, and they are equal in length.
Answer:
1:18 to scale
Step-by-step explanation:
2 goes into 36 18 times so its scaled down by 18.
PART A - So the ruler is 22.86 centimeters tall, and after measuring with an inch ruler, is also 9 inches tall.
ruler = 22.86cm
ruler = 9 in
You can equate 22.86cm and 9in because they both equal the length of the ruler (transitive property).
22.86cm = 9in
Then you can write a proportionality equation.
Part B -
Cross multiplying,
Part C - We can use something called dimensional analysis - multiplying 12 cm by (1in/2.54cm) - in order to change the units from inches to cm. This is possible because 1in = 2.54cm, the fraction 1in/2.54cm = 1. And also the units cm will cancel out.
Answer:
-96/7x
Step-by-step explanation:
-4/7+2/7x-14x+4/7
-4/7+4/7+2/7x-14x
2/7x-14x
2/7x-98/7x
-96/7x
