e.
Step-by-step explanation:
9. He needs 0.4 m³ of concrete
1 m³ concrete costs €72.50
0.4m³ = x
we represent x buy the cost of concrete he'll need since we don't know
we cross multiply,
1 m³ = 72.50
0.4 = x
x = 72.50 × 0.4
x = € 29.00
10. 1 meter of hose = $ 3. 40
4.5 meter of hose = x
we cross multiply,
X= $ 15.3
11. 6 timbers, each has 3.9 m long
total meters = 6 timbers × 3.9 m
= 23. 4 meters
extra meter he needs = (25 - 23.4) m
= 1.6 m
12. 5700 pies, each has mass of 0.26kg
3600 pasties, each had mass of 0.26kg
a. Total mass of pies, 5700 × 0.26kg = 1,482kg
b. Total mass of pasties , 3600× 0.26kg = 936kg
c. total mass of pies and pasties
=( 3600× 0.26+ 5700× 0.26) kg
= 2418kg
d. the total mass of the pies and pasties is 2418kg
each heated van weighs 500kg
the number of heated vans = 2418kg/500
= 4.836kg is almost 5 vans
