Hello!
The number is 4.35, which is either between 4 ft or 5 ft. To round it, you need to see whether the number is above 5 or below. If it's over 5, you round up. If it's below 5, you round down.
4.35
Look at the numbers after the decimal point. 35. Since the second digit is 5, we round the 3 to a 4. Making it 4.4
Since 4 is less than 5, you round it down. 4.4 --- 4
So, 4.35 rounded to the nearest ft is 4 ft.
Rounding confuses me, too! :D
Answer:
That would be sina.
Step-by-step explanation:
sin(a+b) = sinacosb + cosasinb
sin(a-b) = sinacosb - cosasinb
Adding we get sin(a+b) + sin(a-b) = 2sinaccosb
so sinacosb = 1/2sin(a+b) + sin(a-b)
Answer:
Jaylen's conclusion is a valid conclusion because it is logical
Step-by-step explanation:
Jaylen's conclusion is a valid conclusion because it is logical. Regardless of not having all the necessary information needed to prove that the number of dogs is the sole main cause for an increase in cleaner usage she can still conclude this. Since dogs naturally bring in dirt from outside and make messes, and since Jaylene notices that families that are known to have more dogs are buying more floor cleaner then she can logically come to this conclusion.
Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
