Answer:
The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Step-by-step explanation:
The first step will be to find the diagonal of the rea life mural.
We can use Pythagoras' Theorem to do this.
Diagonal = =47.43 feet.
Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.
This will be 47.43 / 6.3 units = 7.53.
The scale factor is 7.53
To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.
This will be
Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976
Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
<u>ANSWER:
</u>
The engine have 5.39 qt approximately.
<u>SOLUTION:
</u>
Given, a specific cars engine has a capacity of 5.1 L of oil.
We need to find how many quarts of oil does the engine have?
Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.
We know that, one liter of liquid contains 1.056 quarts approximately.
Number of quarts of oil = number of liters of oil x number of quarts per liter.
Number of quarts of oil = 5.1 liters x 1.056 quarts.
Number of quarts of oil = 5.1 x 1.056
Number of quarts of oil = 5.389 qt.
Hence, the engine have 5.39 qt approximately
