Answer:
2^12x3^5x5^5
Step-by-step explanation:
- The problem gives us the pieces of mail delivered per second and the amount of seconds in six days, so to find the pieces of mail delivered in six days we need to multiply pieces per second by seconds in six days.
-The pieces of mail delivered per second is 2^4x3x5^3, and seconds in six days is 2^8x3^4x5^2, therefore we must multiply (2^4x3x5^3)x(2^8x3^4x5^2)
-When multiplying powers with the same base, you need to add the exponent, for example 2^4 has the same base as 2^8, so when multiplying 2^4 and 2^8, we would have a product of 2^12
-Repeat this process with the remaining powers:
-3x3^4=3^5
-5^3x5^2=5^5
-Write the expression with the three powers
2^12x3^5x5^5

Answer:
x = 18 cm
y = 9 cm
Step-by-step explanation:
An open-top box will have minimum surface area when it is in the shape of half a cube. The whole cube would have volume 2×2916 = 5832 cm³, so its side length would be ∛5832 cm = 18 cm.
The dimensions of the box are x = 18 cm; y = 9 cm.
__
The surface area is x^2 +4xy, where y = 2916/x^2. That is, the surface area is ...
S = x^2 +11664/x
Setting the derivative to zero, we find ...
dS/dx = 0 = 2x -11664/x^2
x^3 = 5832 . . . . . . . . may look familiar
x = ∛5832 = 18
y = 2916/18^2 = 9
Answer:
The answer is 0.04a² - 0.04ab - 0.15b²
Step-by-step explanation:
(0.2a - 0.5b) ( 0.2a + 0.3b)
0.04a² + 0.06ab - 0.1ba - 0.15b²
0.04a² + 0.06ab - 0.1ab - 0.15b²
0.04a² - 0.04ab - 0.15b²
Thus, The answer is
0.04a² - 0.04ab - 0.15b²

Hello,
If we draw the line AM intercept DC in F,
using the theorem of Thales:
LM/DF=1/2
==>
(4x+3)/(187+x+8à=1/2
==>8x+6=195+x
==> 7x=189
==>x=27
