Weight of an grapefruit=weight of an orange+8% weight of an orange
weight of an apple=weight of an orange -10% weight of an orange
a.<span>By what percentage is the grapefruit heavier than the apple?
We should find the connection between grapefruit and an apple. We know the connection between the weight of a grapefruit and an orange, we know the connection between an orange and an apple, so this means we know the connection between a grapefruit and an apple.
</span>
weight of an grapefruit=weight of an <span>orange+8% weight of an orange
</span>weight of an orange=weight of an apple<span> +10% weight of an apple
</span>
-> weight of an grapefruit=weight of an apple+10% weight of an apple + 8%(weight of an apple+10% weight of an apple)= weight of an apple + 18% weight of an apple + 2% weight of an apple= <span>weight of an apple + 20% weight of an apple
</span><span>b.By what percentage is the apple lighter than the grapefruit?
</span>weight of an grapefruit=weight of an apple + 20% weight of an apple<span>
</span>
-> The apple ts 20% lighter than the grapefruit.

Step-by-step explanation:
35/36= 0.972222
The postulate that justifies the statement below the given diagram is the: angle addition postulate.
<h3>What is the Angle Addition Postulate?</h3>
According to the angle addition postulate, the sum of the measures of two angles that make up a bigger equals the measure of the bigger angle.
Two small angles, MRO and MRS add up to give the bigger angle, SRO, which contains both angles.
Therefore, the postulate that justifies, m∠MRO + ∠MRS = m∠SRO, is: angle addition postulate.
