Answer:

i) 1.25m

ii) 32 books

Step-by-step explanation:

60 identical books occupies = length of 1.5m

(i) the length occupied by 50 such books on

a shelf,

If:

60 books = 1.5m

50 books = y m

60 × ym = 1.5 × 50

ym = 1.5 × 50/60

= 1.25 m

Therefore, 50 of such books occupies a length of 1.25m

(ii) the number of such books needed to completely

occupy a shelf that is 80 cm long.

100 cm = 1m

80 cm = x m

Cross Multiply

xm = 80/100

= 0.8 m

If : 1.5 m = 60 books

0.8 m = y books

Cross Multiply

= 1.5m × y books = 60 books × 0.8m

y books = 60 books × 0.8m/1.5m

y books = 32 books

Therefore, 32 books occupies a shelf that is 80 cm or 0.8 m long

slavikrds [6]

Answer:

10.9

Step-by-step explanation:

Pythagoras theorem- a² + b² = c²

Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.

7² + 8.44² = c²

= 49 + 70.56 = c²

= 119.56 = c²

∴ c = √119.56

= 10.9

WITCHER [35]

Answer:

Cost to a rent a snorkel $=\$ 12$ , Cost on 10 rent snorkel $=\$ 120$

Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin= $\$ 168$

10 snorkel and 12 pairs of fin

Let the cost to rent a snorkel be = $\$$ x

and cost of a pair of fin is = $\$$ y

x=3y (given condition)

$10x+12y=168$

$10\times 3y+12y=168$

$30y+12y=168$

$42y=168$

$y=168/42$

$y=4$

Cost of a pair of fin= $y=\$ 4$

$x=3y$

$x=3\times 4$

$x=12$

Cost of rent a snorkel $=\$ 12$

Total cost of a rent snorkel

$=10\times 12$

= $\$ 168$
