Answer:
3 minutes
Step-by-step explanation:
Let's say that the bathtub is 15L
It would take 7.5 mins to fill 15L
15L/7.5 = 2L per minute
The other tap would take 5 minutes to fill 15L
15L/5 = 3L per minute
3L per minute + 2L per minute = 5L per minute
15L/5L per min = 3 minutes

hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a =0 and b = 0 (Center at the origin)
r = OP....p(-8,3)
r² = (OP)²
r² = (-8-0)² +(3-0)² = 64+9=73
an equation of the circle that satisfies the stated conditions.
Center at the origin, passing through P(-8, 3) is : x² +y² = 73</span></span>
$36.36 = 110%.
$36.36 ÷ 1.1 = $33.054
(the five and the four are recurring)
(I divided by 1.1 because 1.1 is 110%)
Answer:
The vertex of the function f(x) is at (2,-7)
Step-by-step explanation:
The function is given to be f(x) = |x-2| -7
Now, f(x) = x - 2 - 7 = x - 9 for, (x - 2) ≥ 0, ⇒ x ≥ 2 ............ (1)
and f(x) = 2 - x - 7 = - x - 5 for, (x - 2) < 0, ⇒ x < 2 .............. (2)
Now, solving equation (1) and (2), we get, x - 9 = - x - 5
⇒ 2x = 4
⇒ x = 2
And hence, from equation (1) we get, y = x - 9 = 2 - 9 = - 7
Therefore, the vertex of the function f(x) is at (2,-7) (Answer)
