Let's say that the weight of the orange is x and the weight of the pineapple is y.
The weight of the pineapple is 7 times that of the orange, so
y = 7x.
Also, y = x + 870.
Therefore, 7x = x + 870.
If we take away x from both sides, we get 6x = 870
If we divide both sides by 6, we get x = 145.
Therefore, the weight of the orange is 145 g.
Also, 145 + 870 = 1015.
So the weight of the pineapple is 1015 g.
To convert grams into kilograms, they must be divided by 1000.
Therefore, the weight of the orange in kilograms is 145/1000 = 0.145 kg
And the weight of the pineapple is 1015/1000 = 1.015 kg.
Answers:
a. 145g for the orange and 1015g for the pineapple.
b. 0.145kg for the orange and 1.015kg for the pineapple.
The weight of the granite pyramid in tons is 1350 tons.
<h3>How to find the weight of the pyramid granite in tons?</h3>
A pyramid is a three-dimensional shape.
The granite pyramid is 50 feet high and has a square base of 30 feet on a side.
Granit weighs 180 pounds per cubic foot.
Therefore, the weight in tons of the pyramid can be calculated as follows;
Hence,
volume of the granite pyramid = 1 / 3 b² h
Therefore,
volume of the granite pyramid = 1 / 3 × 30² × 50
volume of the granite pyramid = 45000 / 3
volume of the granite pyramid = 15000 ft³
Hence,
1 ft³ = 180 pounds
15000 ft³ = ?
weight = 2700000 pounds
1 pounds = 0.0005 tons
2700000 pounds = ?
Therefore,
weight of the pyramid granite in tons = 1350 tons
