Answer:
60 days.
Step-by-step explanation:
Let the actual time be x, then:
x - 0.25x = 45
0.75x = 45
x = 45/0.75
= 60 days.

Answer:
x = 2
Step-by-step explanation:
Given 2 secants intersecting a circle from an external point, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20
Subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Answer:
7
Step-by-step explanation:
A rectangle has a length that is 8 times the width
The area of the park is 392 square units
Let y represent the width of the park
Since the length is 8 times the width then, l= 8x
Therefore the width of the park can be calculated as follows
8x × x= 392
8x^2= 392
x^2= 392/8
x^2= 49
x= 7
Hence the width of the park is 7
