No, all three lines are parallel. If line c was perpendicular to the line a, and because line b is parallel to the line a, both line a and b would be perpendicular to the line c (line b has to be parallel to the line c, therefore it's impossible)
The vertex of this function should be (6,-4). Since the function is in vertex form.
Answer:
20 hours
Step-by-step explanation:
The volume of water when the pool is 80% full can be found using the proportion ...
2250/75% = v/80%
v = (80/75)(2250) = 2400 . . . cubic meters
Emptying at the rate of 120 m³/h will take ...
time = volume/rate
time = (2400 m³)/(120 m³/h) = 20 h
It will take 20 hours to empty the pool from 80% full.
Answer:
<h3>The answer is 10600 cm²</h3>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
r = 58 cm
The area of the circle is
A = 58²π
= 3364π
= 10568.3176866761...
We have the final answer as
<h3>10600 cm² to 3 significant figures</h3>
Hope this helps you
Let x be the total number of marbles.
(x-4) is divisible by 6, 7 and 8., Calculate the LCM of 6, 7, and 8
(LCM = 8x3x7 = 168)
Then (x-4) = 168 and X = 172 (least possible number of marbles)
