Karinna's aquarium can hold 80 liters, which is equal to 80,000 cm'. The base measures 100 cm by 40
tresset_1 [31]

Answer:height=20cm

Step-by-step explanation:

Length=100cm

Breadth=40cm

Volume=80 liters which is equal to 80000cm^3

volume=length x breadth x height

80000=100 x 40 x height

80000=4000 x height

Divide both sides by 4000

80000/4000=(4000xheight)/4000

20=height

Height=20cm

Ashley and Gabby bought lunch from the food trucks on Sugar Day. Ashley bought 3 tacos and a drink for $7. Gabby bought 2 drinks
kramer

Answer:

$1.5

Step-by-step explanation:

This would be solved using a simultaneous equation

let tacos = t

drink = d

3t + d = 7 -- eqn 1

2t + 2d = 8 -- eqn 2

Multiply equation 1 by 2 to derive equation 3

6t + 2d = 14 eqn 3

Substract equation 2 from equation 3

6t + 2d = 14 -- eqn 3

         -

2t + 2d = 8 -- eqn 2

= 4t = 6

solve for t

6/4 = 1.5

= $1.5

The perimeter of a regular 5-sided figure is 25 units, and the length of each side is x + 2 units. What is the value of x?
Usimov [2.4K]

Answer:

x = 3 un

Step-by-step explanation:

25 ÷ 5 = 5

Each side must be 5 units.

5 un - 2 un = 3

x = 3 un

Check:

3 un + 2 un = 5 un

5 un + 5 un + 5 un + 5 un + 5 un = 25 un
