<u><em>Answer:</em></u>
The length of the diagonal is 284 km
<u><em>Explanation:</em></u>
<u>1- we get the side length of the side:</u>
We are given that the land has a square shape and an area of 40,404 km²
Area of square = (side)²
40,404 = (side)²
side = +√40,404
side = 201.007 km ≈ 201 km
<u>2- we get the length of the diagonal:</u>
Refer to the attach picture representing the area of land.
We can infer that the two side lengths along with the diagonal of the land form a right-angled triangle.
Therefore, to get the diagonal, we can apply the Pythagorean theorem as follows:
Diagonal = 284.2 ≈ 284 km
Hope this helps :)
Answer:
Consider the complete question is,
'For each customer, a bakery charges p dollars for the first loaf of bread bought by the customer and charges q dollars for each additional loaf bought by the customer. What is the value of p ?
(1) A customer who buys 2 loaves is charged 10 percent less per loaf than a customer who buys a single loaf.
(2) A customer who buys 6 loaves of bread is charged 10 dollars.
Solution :
Since, the charges of first loaf = p dollars,
Charges for each additional loaf = q dollars
Thus, the total charges for x additional loaf = p + qx
Charges for 1 loaf = p,
Charges for 2 loaf per loaf = (p + q)/2
According to the question,
.....................(1),
Again according to the question,
p + 5q = 10 .....................(2),
Equation (2) - 5 × equation (1),
p + 4p = 10
5p = 10
⇒ p = 2
Hence, the value of p would be 2.
