Answer:
1) 194
2) 480
3) 144
4) 2m > 84 $
4m > 168 $
10m> 420 $
13m> 546$
Step-by-step explanation:
1) 582 in 30 mins ... so in third the time 582÷3 = 194
2)120 tools in 5 hours , so 120 ÷ 5 = 24 tools per hour > so 24 × 20 = 480
3) 1kg is for 18$ ... so 8kg will be 8 × 18 = 144
4) 5meters cost 210$ , one meter costs 210÷5 =42
now multiply , 2×42 = 84 , 4×42 = 168 , 10×42= 420 , 13×42 = 546
sorry the last question isn't showing for me , i can't see it
Answer:
3a, 13cm 5, 1:200
Step-by-step explanation:
In the question 3 you just have to divide all of those numbers with that 5000, maybe also make them cm so it makes more sense. So 650m = 65000cm:5000= 13cm
then for the question 5, make the km to cm, so 4.2km would be 420000cm. Then you have to divide that 420000cm with the 21 cm, so 420000:21= 200. Then the scale should be 1:200
I had difficulties with these as well. If you need extra help with the task 3 please pm me :)

Answer:
a. 2.3 sec and 5 sec
Step-by-step explanation:
The graph is symmetrical about the time (t) that makes d=0. That makes the line of symmetry be ...
110/30 = t ≈ 3.67
This will be the average of the two times, so their sum is ...
t1 +t2 = 2×3.67 = 7.3
Only one answer choice has a sum of 7.3 seconds:
2.3 sec and 5 sec
