Answer:225000 mice
Step-by-step explanation:
Mass of elephant=4500kg
Mass of mice=2x10^(-2)=2/100 kg
Let y be there number of mice
2/100 x y=4500
2y/100=4500
Cross multiply
2y=4500 x 100
2y=450000
Divide both sides by 2
2y/2=450000/2
y=225000
Answer:
5x4°x7
Step-by-step explanation:
5x°+2x-1 when x =4
5x4°+2x4-1
5x4°+8-1
=5x4°x7
Answer:
20.
Given, complex number is 10+5i .
We need to find sum of the given complex number and its conjugate. The conjugate of 10+5i is 10-5i. Therefore, the sum will be 10+5i+10−5i=20.
the x s are the independent variable so any direct change to them is changing the independent. like the second one has -5 on the x
