The base of a triangle is 4 inches more than 8 times its height.
Zanzabum

Answer:

12

Step-by-step explanation:

The area of a triangle is given by A=1/2bh, and from the first line give sus b=4+4h. Therefore we get A=(1/2)(4+4h)h=12. Or (2+2h)h=12. We can simplify further by dividing both sides by 2, and we get (h+1)h=6 or multiplying out h^2+h=6 which gives h^2+h-6=0. This we can factor into (h+3)(h-2)=0 or h=2, or -3. We have a positive hight, therefore, h=2 which gives us a base of b=4+4*2=12. So a base of 12inches. and a hight of 2 inches. We can plug this into the original area formula and see we get an answer of 12

Walnuts peanuts and chocolate chips are mixed in a ratio of 7:2:5. What is the weight of the mixture if 2.5lbs of chocolate chip
andreyandreev [35.5K]
In plain and short, we simply will divide the whole amount of 2.5lbs by (7+2+5), and then distribute accordingly to each component,

\bf \stackrel{walnuts}{7}~~:~~\stackrel{peanuts}{2}~~:~~\stackrel{chocolate}{5}
\\\\\\
\stackrel{walnuts}{7\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{7+2+5}}

\bf \stackrel{walnuts}{7\cdot \frac{2.5}{14}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{14}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{2.5}{2}}~~:~~\stackrel{peanuts}{\frac{2.5}{7}}~~:~~\stackrel{chocolate}{\frac{12.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{5}{4}}~~:~~\stackrel{peanuts}{\frac{5}{14}}~~:~~\stackrel{chocolate}{\frac{25}{28}}
