Answer:
75π
Step-by-step explanation:
volume of a cone
=1/3 × π × r^2 × h
=(225π)/3
=75π
Explanation:
The starting system is:
{
0.4
x
−
0.1
y
=
2
0.2
x
+
0.5
y
=
1
If we multiply the second equation by
−
2
the coefficients of
x
will be opposite numbers:
{
0.4
x
−
0.1
y
=
2
−
0.4
x
−
y
=
−
2
Now we can add both sides of the equations to get an euation of 1 variable:
−
1.1
y
=
0
y
=
0
Now we have to substitute the calculated value of
y
to calculate
x
:
0.4
x
=
2
x
=
2
0.4
=
20
4
=
5
Answer:
The solution of this systemm is:
{
x= 5
Y=0
I hope that helps let me know if you have questions.
A= 2 to the power of -1
Because if it's the same base no in multiplication we add the indices and in division we subtract the indicies
Answer:
Step-by-step explanation:
(9 - 7)/(4 + 2) = 2/6 = 1/3 is the slope of the line
So we know that the Bruno's BAkery uses 4/9 barrels and that Cosmo's Bakery uses 6/5 as much. So we have to multiply 4/9 * 6/5 which is equal to 0.53 for one day.
Since they are asking for the 3/7 of the week we multiply 3/7 *0.53.
This is equal to 0.23 or 23/100
