The answer is 44.
40 / 100 = 0,4 * 10 = 4 (10%)
40 + 4 = 44
Answer: 3 4 4 5 5 5 5 7 7
Step-by-step explanation:
your answer is 5 because 5 is the number in the middle
So when the pool is filled by the two hoses together in 30 minutes, the larger hose itself fills 30/40 = 3/4 of the pool. That means in those 30 minutes the smaller hose fills 1/4 of the pool; and that means it would take the smaller hose 30*4 = 120 minutes to fill the pool alone.
Answer:
B
Step-by-step explanation:
The standard form of the equation of a circle is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (2, - 9) and r = 3, thus
(x - 2)² + (y - (- 9))² = 3², that is
(x - 2)² + (y + 9)² = 9 → B
