The 2 is in the tenths place, therefore we look at the number after to determine what to do with it. The number after is an 8 therefore we must round the two up to a 3. Therefore the answer is 310.3
Answer:
SinA = √5/3
CosB = √5/3
Step-by-step explanation:
First let us find the value of a. This is illustrated below:
a^2 = 6^2 — 4^2
a^2 = 36 — 16
a^2 = 20
Take the square root of both side
a = √20 = √(4 x 5) = √4 x √5
a = 2√5
From the diagram,
For sinA
Opp = 2√5
Hypo = 6
Adj = 4
SinA = opp /Hypo
SinA = 2√5/6
SinA = √5/3
For CosB
Opp = 4
Hypo = 6
Adj = 2√5
CosB = Adj /Hypo
CosB = 2√5/6
CosB = √5/3
Answer:
b-11
Step-by-step explanation:
Just do b-11
Have a nice day.
PS I don't really know what the question is asking..
Answer: 175 robberies
Step-by-step explanation:
Robberies last year= 243
Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.
Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.
There are 175 robberies this year
