The ratio will always be 3.14
If the ratio is 6:7 the students should divide nicely into 6+7=13 parts. Six of those parts are girls, seven of those parts are boys.
364 / 13 = 28
So 6 × 28 = 168 girls
Answer: 168
Check:
7 × 28 = 196 boys
168 + 196 = 364, good
Y= -2X
Y= -2•3
Y= -6
X=3
Y= -2X
Y= -2•(-3)
Y=6
X= -3
Answer is y= -2X
Answer:
1.860 to 4sf
Step-by-step explanation:
Answer:
162.4 in²
Step-by-step explanation:
LETS GET INTOOOOEEETTT
Let's start with what we know:
Area of regular octagon = 1/2 x perimeter x apothem
We know the apothem, so all that we need to find to fill in the above equation is the perimeter:
perimeter = 8 x 5.8 = 46.4in
Now we can fill in our original equation and solve:
Area of regular octagon = 1/2 x perimeter x apothem
Formula = n (s/2)² divided by tan( π /n)
= 8 (5.8/2)² divided by tan ( π /8)
= 162.4283 in²
ORRR when rounded to the nearest tenth,
=162.4 in²
