Kyla makes a triangular school pennant. The area of the triangle is 180 square inches. The base of the pennant is z inches long.
kykrilka [37]
We can represent the base as z and the height as 2z+6. We are going to use the formula A=1/2*b*h and solve for z
180=1/2*z*(2z+6)
360=2z^2+6z 
0=2z^2+6z-360
0=2(z^2+3z-180)
0=(z+15)(z-12)
So z=-15 and 12 but it must be positive so then the base is equal to 12

When we plug this into 2z+6 we get 30 for the height
2(12)+6=30

Hope this helps

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.
Verizon [17]

Answer:

The volume of the full bottle of Jun's favorite hot sauce in ml is \frac{10x}{9}.

Step-by-step explanation:

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.

Then, 90% of the full bottle sauce is equal to x ml.

So, 1% of the full bottle sauce is equal to \frac{x}{90} ml.

Therefore, 100% of the full bottle sauce is equal to \frac{x}{90}\times 100 = \frac{10x}{9} ml.  

Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is \frac{10x}{9}. (Answer)
