Alinara [238K]

Answer:

One triangle can be constructed.

Step-by-step explanation:

Recap that all the interior angles in a triangle add up to 180. With the given measurements of the angles, 70 plus 80 plus 30 equals 180. Each triangle has the sum of 180 degrees. Therefore, there can only be one triangle that can be constructed. I think you were suppose to put can, not can't. Hope this helps!

Kenny bought a 50-pound bag of chicken feed for $29.98 and a 25-pound bag for $15.49. Can you use proportional reasoning to find

Alla [95]

$\frac{50 \: lbs}{29.98} = \frac{1 \: lb}{0.596}$
$\frac{ 25 \: lbs}{15.49} = \frac{1 \: lb}{0.6196}$
$\frac{1 \: lb}{0.596} < \frac{1 \: lb}{0.6196}$
Since the proportions are different, it's best to say that to determine the price of a 40-pound bag, proportional reasoning is no where to be found so no, proportional reasoning cannot be used to find the price of a 40-pound bag!
