28 dogs are present
Step-by-step explanation:
Dogs : Cats
= 4 : 7
= ? : 49
= 4 x 7 : 7 x 7
= 28 : 49
<span>Simplify the left side.
</span>−2x+6=<span>10
</span>Move all terms not containing xx to the right side of the <span>equation
</span>−2x=<span>4
</span>Divide each term by <span>−2-2</span><span> and simplify.
</span>x=<span>−<span>2</span></span>
Let C₀ be current consumption. Then consumption (C) after t years is:
<span>C(t) = C₀ * (1 + 0.1)^t </span>
<span>C(t) = C₀ * (1.1)^t </span>
<span>After 10 years, consumption will be: </span>
<span>C(10) = C₀*(1.1)^10 </span>
<span>C(10) = 2.5937424601 C₀ </span>
<span>Total percentage increase after 10 years: </span>
<span>(2.5937424601 C₀ - C₀) / C₀ = 1.5937424601 C₀ / C₀ = 1.5937424601 = 159.37% </span>
<span>Utility company will have to increase generating capacity by 159.37%</span>
