Answer:

70 m²

Step-by-step explanation:

Red sides:

2 x ( 5 x 5 ) = 2 x 25 = 50

Blue side :

2 x ( 1 x 5) = 2 x 5 = 10

Green :

2 x ( 1 x 5 ) = 2 x 5 = 10

Total surface area:

50 + 10 + 10 = 70

Units : m²

Surface Area = 70 m²

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9. How much alloy can be produced using 4.9 lb of zinc?
Wittaler [7]

Ratio of Nickel to Zinc:

( 2/7 ) = ( Nickel /4.9)

Nickel = 1.4 lbs.

Ratio of Copper to Zinc:

( 9/7 ) = ( Copper /4.9)

Copper = 6.3 lbs.

Alloy = Zinc + Nickel + Copper

Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

Alloy = 12.6 lbs.

Hope this answer will be a good h<span>elp for you.</span>

The capacity of cylinder tank is 539 litres . if its height is 1.4m then find the area of base
Dennis_Churaev [7]

Step-by-step explanation:

Solution:

Here,

Volume of the tank=539 litres

=539×1000cm^3=539000cm^3

Height=1.4×100cm=140cm

Let the radius of the base be r cm

Then,

22/7×r^2×140=539000

or,r^2=539000×7/22×140

or,r^2=1225

or,r=35 cm

So,

Area of base=pie r^2

=22/7×35^2

=3850 cm^2
