Answer:
408 neighbours, 7 each
Step-by-step explanation:
2856 is divisible by 7
So each gets 7
Neighbours: 2856/7 = 408
Step-by-step Answer:
AN is height, so A is perpendicular to BC. (See image attached).
BN = 18
AN = 24
AC = 40
All as labeled.
ABN is a right triangle, with AB = sqrt(18^2+24^2)=sqrt(324+576)=30
ACN is a right triangle, with CN = sqrt(40^2-24^2)=sqrt(1600-576) = 32
=>
BC = BN + NC = 18 + 32 = 50
Answer:
no they are parallel because the slope is the same they just are at different y- intercepts
Answer:
2x+23
Step-by-step explanation:
20 inches is 400
10 inches is 200
5 iches is 100
So 20+10+5=35
Which means 400+200+100= 700
So the frequency of a 35 inch string is 700 cycles per second
