Answer: The square root of 135 is between 11 and 12
Step-by-step explanation:
10 x 10 = 100 → too low
11 x 11 = 121 → between 121
12 × 12 = 144 → and 144
13 x 13 = 169 → too high
Therefore, the square root of 135 is between 11 and 12.
Answer = 688 thousand / 688,000
Explanation - 536-517 = 19 so 19000 x 8 + 536000 = 688,000
Answer: speed = 22 meters/minute
distance = 500 meters
by using the formula, speed = distance/time,
therefore, time = distance/speed
t = 500/22
t = 22.72 minutes
Answer:
see explanation
Step-by-step explanation:
to find the zeros let f(x) = 0
1
f(x) = 0 , that is
x(x + 10) = 0
equate each factor to zero and solve for x
x = 0
x + 10 = 0 ⇒ x = - 10
2
f(x) = 0 , that is
x(x - 3) - 4(x - 3) = 0 ← factor out (x - 3) from each term on the left side
(x - 3)(x - 4) = 0
equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 4 = 0 ⇒ x = 4
