A pet store was selling 2 lizards for
$14.48. If they ended up selling 6
lizards, how much money would they
have earned?

Answers

Answer:

43.44

Step-by-step explanation:

If they are selling 2 lizards for 14.48 you would divide

14.48 by two which is 7.24.

This means the lizards are 7.24 each.

7.24x6 is 43.44

Answer:

$43.44

Step-by-step explanation:

If two lizards are worth $14.48, then you just need two multiply the cost by three.

If a lizard can run 8 m across the water in 4 seconds, how
fast is he traveling?

Answers

Answer:

2 meters/second

Step-by-step explanation:

Equation for speed is:

s = d/t

Plug in the 8m for distance(d)

Plug in the 4 seconds for time(t)

So now you have s = 8m/4sec

This simplifies to s = 2 m/sec

The lateral surface area of a cube is 400cm². Its total surface area is
_______
a)600cm² b) 2400cm² c) 500cm² d) 650cm²

Answers

Answer:

Step-by-step explanation:

Lateral surface area of cube = 4a²

4a² = 400

   a² = 400÷4

  a² = 100

 a = √100 = √10*10

a = 10 cm

Total surface area = 6a²

                               = 6 * 10²

                               = 6* 100

                               = 600 cm²

A construction company orders tile flooring for the kitchen and three bathrooms of a new home. The kitchen floor measures 48 square feet. Two bathrooms have floors that each measure square feet. The third bathroom floor measures square feet. If the tile costs $2.39 per square foot, what's the least amount of money, to the nearest cent, the company spends on tile for all three bathrooms

Answers

Step-by-step explanation:

The question is incomplete. Let us assume the two bathrooms have floors that each measure 24 square feet and third bathroom floor measures 18 square feet.

For the two bathrooms, the total area will be 2*24 = 48 square feet

Since the third bathroom measures 18 square feet, the total square feet for the  3 bathrooms is equal to 48sq. ft + 18 sq.ft = 64sq. ft

If the tile costs $2.39 per square foot, then the amount that 64sq. ft tiles will cost is expressed as:

1 sq. ft = $2..39

64sq.f = $x

Cross multiply:

1*x = 2.39* 64

x = $152.96

Hence the amount that the company's spent on tiles for the three bathrooms will be 15296 cents.

Note that the dimensions of bathrooms were assumed. You can follow the same procedure for any dimension given.

Subtract 2 from two, and get 0.

4b = -b

this means that the only possible case where the equation is satisfied is when b = 0, because -0 is 0, and 4x0 is still 0.
