Answer:
the dogs daily energy intake is 643.5 kcal
and, the dogs daily protein intake is 41.8275 grams
Step-by-step explanation:
Given:
Food taken per day = 2 × cup = 1.5 cup
Amount of calories in a cup = 429 kcal/cup
Amount of protein = 6.5 grams per 100 kcal of energy
now,
The total amount of calories taken per day
= Number of cups of food × Amount of calories in a cup
= 1.5 × 429
= 643.5 kcal
also,
100 kcal of energy = 6.5 grams protein
thus,
1 kcal of energy = 0.065 grams protein
therefore,
643.5 kcal of energy = 0.065 × 643.5 grams protein
or
643.5 kcal of energy = 41.8275 grams of proteins
Hence,
the dogs daily energy intake is 643.5 kcal
and, the dogs daily protein intake is 41.8275 grams
<u>Solution-</u>
Given that,
In the parallelogram PQRS has PQ=RS=8 cm and diagonal QS= 10 cm.
Then considering ΔPQT and ΔSTF,
1- ∠FTS ≅ ∠PTQ ( ∵ These two are vertical angles)
2- ∠TFS ≅ ∠TPQ ( ∵ These two are alternate interior angles)
3- ∠TSF ≅ ∠TQP ( ∵ These two are also alternate interior angles)
<em>If the corresponding angles of two triangles are congruent, then they are said to be similar and the corresponding sides are in proportion.</em>
∴ ΔFTS ∼ ΔPTQ, so corresponding side lengths are in proportion.
As QS = TQ + TS = 10 (given)
If TS is x, then TQ will be 10-x. Then putting these values in the equation
∴ So TS = 3.85 cm and TQ is 10-3.85 = 6.15 cm
