Answer:
480
Step-by-step explanation:
60% of 800
= × 800
= 0.6 × 800
= 480 ← number of students who take the bus
Interior angle add up to 360, so you add
(a+10) + (3a+10) + (5a-10) + (3a-10) = 12a
12a =360
a= 30
30+10=40
3(30)+10=100
5(30)-10=140
3(30)-10=80
You can double check they're correct by doing 40+100+140+80, which equals 360.

Answer:
i believe stays 3
Step-by-step explanation:
it’s still the majority
Let w be the width of the second garden. Then, its' length is 2w+4. So:
w(2w+4)=70
2w²+4w-70=0
w²+2w-35=0
(w+7)(w-5)=0
w=5
2w=10
2w+4=14
The first garden is 5m x 10m, the second is 5m x 14m
