Answer:
5^ -7 =1 / 5^7
Step-by-step explanation:
(5^2)-^2/ 5^3
We know that a^b^c = a^(b*c)
(5^2)-^2 = 5^(2*-2) = 5^-4
5^-4/ 5^3
We know that a^b /a^c = a^ (b-c)
5 ^ (-4-3)
5^ -7
If we don't want to use negative exponents
We know that a^ -b = 1/ a^b
1 / 5^7
Use pythagorean theorem for the answer.
a^2 +b^2 = c^2
side + side = hypotenuse
Now try to solve it.
Hope that helps:)
The answer would be:
$2.99 per undershirt.
Explanation:
The cost of the a pack of 6 is $13.98.
This is $3.96 less than 6 undershirts bought separately.
The amount is therefore: $13.98 + $3.96 = $17.94
So the individual prices is $17.94/ 6= $2.99 (DIVIDED BY 6)
HOPE THIS IS HELPFUL :))
X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0' x - 7 = 0 so x = 7
Solution is 0, 7.
Answer:
452.448cm^3
Step-by-step explanation:
Given data
Height= 25cm
Diamter= 12cm
Radius= 6cm
The expression for the volume of a cone is given as
V= 1/3*πr^2h
Substitute
V= 1/3*3.142*6^2*25
V= 1/3*3.142*36*12
V= 1/3*1357.344
V=452.448cm^3
Hence the volume is 452.448cm^3
