I need help with 4 to 9 but do as much as you can (11 points )

Step-by-step 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
