We can use using graphing technology to solve the system of equations here.
So draw sketch of graphs
and
on graphing calculator. you will get sketch as shown
Take pointer to point of intersection as shown. It displays (x,y) coordinate of points of intersection as (9.597, 3.459) as show in figure.
Now round off these values to nearest tenth thats one digit after decimal dot.
so to round 9.597 to one decimal place we will see 2nd decimal digit(next to place where you have to round off) which is 9 here and as 9 is greater than 5 so we will increase 1st decimal place digit by 1, so round to one decimal place will be 9.6.
Similarly to round off 3.459 to one decimal place we will see 2nd decimal digit which is 5. Again as its equals 5 we will increase the 1st decimal digit by 1 for round off. So final round off to one decimal place will be 3.5
So final answer for solution set will be choice C (9.6, 3.5)
Answer: 480 minutes or 8 hours
Step-by-step explanation:
24,000 ÷ 50 = 480.
It will take 480 minutes to fill the pool.
480 minutes ÷ 60 is also 8. So it will take 8 hours to fill the pool, or 480 minutes. Whichever one you want to use.
Hope this helps!
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy .
For x=0, check which equation has y=0.
In option A, .
In option B, .
In option C, .
In option D,
Only in option C, we have a equation of the form with 4 as constant of proportionality and it passes through (0,0).
<h2><u>Therefore, the correct option is C.</u></h2>
We know that
surface area of sphere=4*pi*r²
r=√[surface area/(4*pi)]
for surface area=200.96 cm²
so
r=√[200.96/(4*pi)]------> r=4 cm
volume of a sphere=(4/3)*pi*r³-----> (4/3)*pi*4³----> 268.08 cm³
the answer is
<span>the approximate volume of the sphere is 268.08 cm</span>³
