Answer:
60 x 35 = 2,100
609,000 / 2,100 = 290 km ^ 2
Step-by-step explanation:
Answer:
L = (x - 2) meters
Step-by-step explanation:
The area of the rectangle = (x² - 7x + 10) m²
The width = (x - 5) m
length = ?
Area of a rectangle = length × width
x² - 7x + 10 = L(x -5)
note L = length
divide both sides by (x-5)
(x² - 7x + 10)/(x - 5) = L
L = x² - 7x + 10 / (x -5)
Factorize x² - 7x + 10
find the numbers you can multiply to give you 10 and also add to give you -7
The numbers are -2 and -5. Therefore,
x² - 2x - 5x + 10 = 0
x(x - 2) - 5(x - 2) = 0
(x-5)(x-2) = 0
Let us go back to our division
L = x² - 7x + 10 / (x -5)
x² - 7x + 10 = (x-5)(x-2)
L = (x-5)(x-2) / (x -5)
L = (x - 2) meters
Answer:D) 1 hr
Step-by-step explanation:
Given
Pump A and B can fill tank in
Pump A and C can fill tank in
Pump B and C can fill tank in
Let A be the total hr taken A therefore rate of
Let B be the total hr taken B therefore rate of
Let C be the total hr taken C therefore rate of
-----1
-----2
-----3
Adding 1,2 & 3
thus time taken by A,B and C combined is 1 hr
The answer to the problem is obvious it’s BLANK
