Emu have 2 feet and 1 head
 wombat has 4 feet and 1 head

E = emu
W = Wombat

E +W = 52
2E +4W = 148

E = 52-W

2(52-W) + 4W = 148
104-2W +4W = 148
104 + 2W = 148
2W = 44
W = 44/2 = 22

E = 52-22 = 30

 there are 30 Emus

Carina spent a total of $5.27 buying a pineapple for $3.40 and several pounds of tomatoes that were on sale for $0.85 per pound.
gulaghasi [49]
Okay so I'm going to set up a equation:

5.27= 3.40+ 0.85x, we have our total our price of one pineapple and our variable

next I isolate the variable:

5.27-3.40=0.85x

next:

1.87=0.85x

x= 2.2

she bought 2.2 pounds of tomatoes

the cylindrical part of an architectural column has a height of 305 cm and a diameter of 30 cm find the volume of the cylindrica
SSSSS [86.1K]

Radius(r)= 25 cm = 25/100= 0.25 m
[1 cm = 1/100m]
Height (h)= 3.5 m
Curved surface area of Cylinder= 2πrh
= 2× (22/7) × 0.25 × 3.5
= 2× 22× 0.25 × 0.5
= 2× 0.5 ×22× 0.25
= 1 ×22× 0.25
= 5.5 m²
Curved surface area of 1 Cylindrical column= 5.5 m²
Curved surface area of 10 Cylindrical column= 5.5 × 10= 55 m²
Rate for painting 1 m² of the cylindrical column = ₹ 15.50
Cost of painting 10 cylindrical columns= 55 × 15.50 = ₹ 852.5.
