Martha's total earnings is the sum of her fixed pay pay day and the extra she gains based on the number of toys she sold. Her total earnings may be expressed as,
44 + 2n
Since she desires to earn $80 or more, the inequality is expressed as
44 + 2n ≥ 80
Solving for n from the inequality,
n ≥18
Thus, the answer is the first choice.
<span>Corresponding sides are sides found in two object that are located on the same location. 149. Two figures are said to be congruent when they have the same shape and size or if one object is a mirror image of the other object. Thus, two triangles having the same corresponding side lengths would be considered as congruent shapes. The answer would be true.</span>
Answer: 
Step-by-step explanation:
1. To solve simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.
2. Keeping this property on mind, you can rewrite the expression as following and simplify:
Step-by-step explanation:
Notice that KM = 0.5BC, KL = 0.5AC
and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.
Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)
Perimeter of 3 small purple triangles
= 3 * [24cm * (1/4)]
= 3 * 6cm = 18cm.
Hence Total perimeter of shaded parts
= 12cm + 18cm = 30cm.
