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.

Question 1
inessss [21]

Answer:

Least possible value of b is 9.

Step-by-step explanation:

It is given that 7b-8>4b+16 and b is an odd integer.

We need to find the least possible value of b.

We have,

7b-8>4b+16

Isolate variable terms.

7b-4b>8+16

3b>24

Divide both sides by 3.

b>8

Since b>8 and b an odd integer, therefore the possible values of b are 9, 11, 13, 15, ... .

Hence, the least possible value of b is 9.
