Answer:
40 pieces
Step-by-step explanation:
1m=100cm
6m=600cm
Standard rod=15cm
So, 600/15
=40
420 is divisible by 2,3,4,5,&6..
The slope of the given line is -2, and since perpendicular lines have negative reciprocal slopes, the slope of the line we want to find is 1/2.
Substituting into point-slope form,
Answer:
Step-by-step explanation:
Let c ----> Cat
t ------> Table
f ---------> Frog
From the first figure,
c + t -f = 170 -----------(i)
From the second figure,
f + t -c = 130 ---------(ii)
Add (i) and (ii)
(i) c + t -f = 170
(ii) <u>f + t -c = 130</u> {c & -c and f & -f gets cancelled
2t = 300
t = 300/2
t = 150 cm
The table is 150 cm tall
