Answer:
Explanation:
4.
Given:
10:s
6:y
8:13
Solve:
8/13 = 10/s
s = 65/4 or 16.25 cm
8/13 = 6/y
y = 39/4 or 9.75 cm
5.
Given:
70ft:88ft
o/90ft
n/53ft
Solve:
70/88 = o/90
o = 1575/22 or 71.59 ft
70/88 = n/53
n = 1855/44 or 42.16 ft
6.
Given:
5.7in:9.1in
9.6in:e
11.2in:t
Solve:
5.7/9.1 = 9.6/e
e = 15.33 in
5.7/9.1 = 11.2/t
t = 17.88 in
7.
Given:
74m:48m
43m:u
64m:y
Solve:
74/48 = 43/u
u = 1032/37 or 27.89 m
74/48 = 64/y
y = 1536/37 or 41.51 m
8.
Given:
16cm:o
11.8cm:101 (I can't see if that is a 101 or 10.1 but I can do it both ways)
6.2cm:t
Solve:
11.8cm/101 = 16cm/o
o = 136.95
or
11.8cm/10.1 = 16cm/o
o = 13.69
11.8cm/101 = 6.2cm/t
t = 53.07
or
11.8cm/10.1 = 6.2cm/t
t = 5.3
9.
Given:
AB:AC
AE:AD
EB:DC
ABE:ACD are right angles
DC = P
We know that:
13ft:30ft
AE:AD are unknown
8ft:DC
We are looking for P?
Solve:
13ft/30ft = 8ft/P
P = 240/13 or 18.46
