Answer:
12 cm²
Step-by-step explanation:
Length of rectangle = 5.6 cm
Width of rectangle = 2.1 cm
Area of rectangle = Length of rectangle×Width of rectangle
⇒Area of rectangle = 5.6×2.1
⇒Area of rectangle = 11.76 cm²
11.76 has 4 significant figures in order to write this term in 2 significant terms we round of the term
The last digit in the decimal place is 6. Now, 6≥5 so we round the next digit to 8 we get
11.8
Now the last digit in the decimal place is 8. Now, 8≥5 so we round the next digit to 2 we get
12
∴ Hence the area of the rectangle when rounded to 2 significant figures is 12 cm²
X is the easy one to solve here. A triangle must have 180 degrees. Add 90 to 38 and subtract that value from 180. This results in x = 52 Degrees. Y is a little bit more difficult. Because The two lines are parallel, Angle CDB is equal to the angle just above y-12. That angle is equal to x, in other words. This angle and y-12 must equal 180 when they are added together, as this is the value for degrees of a line. So, 180= (y-12) + 52. Just solve this algebraically, and is should result in y = 140 degrees.
Tldr: y = 140, x= 52
Salutations!
If I began studying at 7:50 and studied until 11:05. How much time did I spend studying?
So let's solve this!
To work out the amount of hours studying, all you have to do I subtract 7:50 by 11:50.
Let's form this into statements!
Starting time = 7:50PM
Finishing time = 11:05
Amount of hours spent in studying = 11:05 - 7:50 = 3:55 hours.
You spent 3 hours and 55 minutes studying.
To be assure your answer, you can add 7:50 and 3:55. It gives you the result of 11:05.
Hope I helped :D
