A shade of green paint is made by mixing blue paint and yellow paint in the ratio of 4 to 3. How many pints of blue paint and ye

nexus9112 [7]

Answer:

$Blue = 12$

$Yellow = 9$

Step-by-step explanation:

Given

$Blue : Yellow = 4 : 3$

Required

Determine the number of pints of each to make 21 of green paints

First, calculate the total ratio.

$Total = 4 + 3$

$Total = 7$

The blue and the yellow pint can be represented individually as:

$Blue = \frac{4}{7} * Green$

$Yellow = \frac{3}{7} * Green$

Number of blue paint calculated last week is:

$Blue = \frac{4}{7} * 21$

$Blue = {4} * 3$

$Blue = 12$

$Yellow = \frac{3}{7} * Green$

$Yellow = \frac{3}{7} * 21$

$Yellow = {3} * 3$

$Yellow = 9$

Recycling one glass bottle can save enough energy to power an oven for 7.5 minutes. A glass bottle weighs 500 grams. Glass used

musickatia [10]

This is a units conversion problem: you have time and you want to convert that to money. Any units conversion problem involves multiplication by 1 in various forms. When you are given 7.5 min = 1 bottle = 500g, you know that (500 g)/(7.5 min) = 1 because the numerator and denominator are equal. (Of course, you are aware that 500 g = 0.500 kg.) The idea is to choose the forms of 1 that cause units you don't want to cancel, leaving only the units you do want.

$6\,h\times \dfrac{0.500\,kg}{7.5\,min}\times \dfrac{60\,min}{1\,h}\times \dfrac{5\,p}{1\,kg}\\\\=\dfrac{6\cdot 0.500\cdot 60\cdot 5\,p}{7.5\cdot 1\cdot 1}=120\,p$

The glass for recycling that would save enough energy to power an oven for 6 hours costs 120p.
