A5 m 60 cm high vertical pole casts a shadow 3 m 20 cm long. find at the same time
(i) the length of the shadow cast by another pole 10 m 50 cm high (ii) the height of a pole which casts a shadow 5 m long
pole which casts a shadow 5m long.

  (i) 6.0 m

  (ii) 8.75 m

Step-by-step explanation:

The pole : shadow length ratio is ...

  5.6 m : 3.2 m = 7 : 4

(i) shadow/pole = 4/7 = ??/10.5

Multiply by 10.5 to get ...

  ?? = 10.5(4/7) = 6.0 . . . meters

__

(ii) pole/shadow = 7/4 = ??/5

Multiply by 5 to get ...

  ?? = 5(7/4) = 35/4 = 8.75 . . . meters

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

over the argument its not good to fight.
