Answer:
It is three times as large
Step-by-step explanation:
If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.
if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.
Zero is greater than 2, so second one from the left.
Answer:
D
Step-by-step explanation:
the median is the middle value of a data set in ascending order
If there is not an exact middle then it is the average of the values on either side of the middle
Arrange data in ascending order
15, 17, 19, 21, 23, 25, 26, 28, 28, 30
the middle is between 23 and 25 , hence
median = 
= 
= 24
Since the precision of the voltmeter is <span>±0.005 V, the effective value range for the first measurement is 9.000 V to 9.010 V, for the second it is 9.001 V to 9.010 V, the third 9.013 V to 9.023 V and the fourth 9.021 V to 9.030 V. From all of these measurements the only one which the accepted value falls within the range is measurement 3.</span>
Answer:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
x-12≤7
Add 12 to each side
x-12+12≤7+12
x≤19
