This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i

A board is cut so that its length is changed from 8 feet to 6.5 feet. What is the percent of change in length? Round your answer
Schach [20]

it went from 8 to 6.5, namely 8 - 6.5 = 1.5.


if we take the 8 to be the 100%, what is 1.5 off of it in percentage?


\bf \begin{array}{ccll}amount&\%\\\cline{1-2}8&100\\1.5&x\end{array}\implies \cfrac{8}{1.5}=\cfrac{100}{x}\implies x=\cfrac{1.5\cdot 100}{8}\implies x=18.75


well, we can round that up to 18.8%, however since it's a subtraction from the board, we can say is -18.8%, a negative percent, because is a percent that was taken out of it.

A box contains 9 green marbles and 17 white marbles. If the first marble chosen was a white marble, what is the probability of c
pshichka [43]

Answer:

16/25

Step-by-step explanation:

Given

Number  of green marbles = 9

Number of White marbles = 17

Total number of marbles = 26

Probability of picking a white marble = 17/26

When a white marble is picked without replacement,

Probability of picking another white marble after first picking a white marble

= 16/25

= 0.64

This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
