Answer:
There will be 9 groups of 8 and 1 group of 6.
Step-by-step explanation:
78/8 = 9.75
This means there will be 9 groups of 8.
The .75 represents the smaller group.
The smaller group consists of 6 people.
You can find the amount of people from .75 x 8, which equals 6.
Answer
62
5.3
65
5.8
2.5
Step-by-step explanation:
FOr the first one we have the opposite and adjacent side, so we'll use TOA
let x= angle
tan(x)=4.7/2.5
x=61.99 or 62
2.) for this one we can just use pathagoryeous thereom
2.5²+4.7²=c²
28.34=c²
c=5.323
3.) For this one we know that the angles in a traingle must add to 180
let x= missing angle
25+90+x=180
x=65
4.) For this one we have the adjacent side but need the hypotonouse
we will therefore use CAH
cos(25)=5.3/x
5.3/(cos(25))=x
x=5.8
5.) For this one we will just use the pathagoryeous to solve for the missing side
a²+5.3²=5.8²
a²=6.107
a=2.5
Answer:
You would multiply both sides by 6.
Step-by-step explanation:
Since they both have 6 already they would just cancel out.
Subtract 7.50 - 4.00 and dived that answer by 10
