Answer:
12/20
Step-by-step explanation:
8+8+4=20
20-8=12
Ok so 2cm on the blueprint is actually 7cm in real life
2:7=1:3.5
for every cm on the map, it is 3.5 times that in real life
so total legnths
17 times 3.5+18 times 3.5+18 times 3.5+19 times 3.5=
59.5+63+63+66.5=
252
answer is 252cm
Answer:
2, 6, 10, 14
Step-by-step explanation:
For the first term, T1
n = 1
4n - 2 = 4 * 1 - 2
= 4 - 2
= 2
Second term, T2
n = 2
4*2 - 2
= 8 - 2
= 6
Third term T3
n = 3
4*3 - 2
12 - 2
= 10
Forth term T4
n = 4
4*4 - 2
= 16 - 2
= 14
Hence, the first four terms are 2, 6, 10, 14
Answer:
p is perpendicular to n. Proved.
Step-by-step explanation:
See the diagram attached.
Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.
It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°
Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}
So, pp' is also perpendicular to nn'. {Proved}
