Peter is making green paint by mixing blue and yellow paint in a cuboid container, shown below. The container has width of 30cm
dusya [7]

Answer: height = 17.5cm

Step-by-step explanation: Peter mixes blue and yellow paint in the ratio 2:3, which means:

\frac{2}{3} = \frac{8.4}{x}

x = \frac{8.4*3}{2}

x = 12.6L

The container is full with the two paints, so total volume:

V = 12.6 + 8.4

V = 21L

Knowing that 1L = 1dm³ and sides of cuboid is measure in cm:

V = 21dm³ = 21000cm³

Volume of a cuboid is calculated as:

V = width*length*height

Height of the container is

height = \frac{V}{width*length}

height = \frac{21000}{30*40}

height = 17.5cm

The height of the container is 17.5cm.

natka813 [3]

Answer: $1090

Since Caroline won $205000 in a lottery and then paid $96000 in taxes, the remaining amount will be:

= $205000 - $96000

= $109000

The interest that the account will earn after just 6 months will be:

Interest = PRT

= 109000 × 2% × 6/12

= 109000 × 0.02 × 0.5

= $1090
