Answer:
90
Step-by-step explanation:
4/15 which is our fraction distance/time
our other fraction is 24/x (x is our variable to find our time)
Now we are doing the buultterfly method
set it up
now multiply 4*x= 4x
15*24=360
now divide 4x ÷ 4 to get our variable alone
do the same to the other side
4 ÷ 360= 90
so x= 90 which is our missing number
hours did it take for oil to cover the area = 592
The correct option is B.
<h3>What is geometrical figure?</h3>
Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.
<h3>According to the given information:</h3>
Given,
Area = 11000m²
Radius = .10m/h
We know the area of the circle:
Area = πr²
The relation between parameter:
Area = πr²
11000 = 3.14 * (0.10t)²
Dividing both side by 3.14
11000/3.14 = (3.14 * (0.10t)²)/3.14
by solving this we get:
(.10t)² = 3503.184
.10t = 59.187
dividing both side by 0.10
t = 59.187/.10
t = 591.877
t = 592
hours did it take for oil to cover the area = 592

Answer:
<h2><em><u>D. 4/25</u></em></h2>
Step-by-step explanation:
As,
0.16
= 16/100
= <em>4/25.</em> [Taking common factor 4 from both 16 and 100]
