Answer:
Option A - 7.3.
Step-by-step explanation:
Given : Number 7.323.
To find : Which number is 7.323 rounded to the nearest tenth?
Solution :
Rounded to the nearest tenth rule :
1) If the hundredths place of a decimal is greater than or equal to five, then tenth place number is added by 1.
2) If the hundredths place of a decimal is less than five, then tenth place number does not change.
In the number 7.323
The Hundredth number is 2 < 5 so tenth number does not change.
7.323 rounded to the nearest tenth is 7.3.
Therefore, Option A is correct.
Answer:
a=15x; b=8x; c=13x
180°=a+b+c=15x+8x+13x=36x
=> x=180÷36=5
=> a=15×5=75°; b=8×5=40°; c=13×5=65°
Answer: (3 , 7)
Step-by-step explanation: When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative. Since x and y are already negative, they become positive due to the double negative rule.
