Answer:

28 weeks

Step-by-step explanation:

subtract 60 from 200 to find the amount of money Jose needs to invest. Then, divide by 5 to find the number of weeks it will take him.

It will take him 28 weeks. If he already has $60 of $200 saved, you would do 200 - 60. That would give you 140. To find out how long it would take him to make $140, you would have to do 140 divided by 5 to get the number of weeks.

Answer:

We have been given an equation $x^2+9x+20=0$

We will factorize it by middle term splitting.

Step 1: $x^2+5x+4x+20=0$

Taking common factors out by clubing first two terms ad last two terms

Step 2: $x(x+5)+4(x+5)=0$

Step 3: $(x+4)(x+5)=0$

Equating both above factors to zero as:

Step 4: $(x+4)=0\Rightarrow x=-4$

And $(x+5)=0\Rightarrow x=-5$ .

How you do multiply complex numbers ? Example : (9 - 4i) (8 + 6i)

Andrew [12]

You multiply them just as you would multiply any normal polynomials, except there is a special rule. Since we know that i = √-1, the rule is that i² = -1. So, let's multiply:

$(9-4i)(8+6i) = 72+54i-32i-24i^2$

Let's simplify this:

$72+22i+(-24*-1)$

$72+22i+24 = 96+22i$

Therefore, your answer is 96 + 22i.

A bag contains three marbles, eight blue marbles and nine red marbles. If the marbles are picked at random, what is the probabil

Phoenix [80]

The probability of obtaining two blue marbles without replacement is equal to 0.15.

We are given that:

The number of yellow marbles = 3

Number of red marbles = 9

Number of Blue marbles = 8

Total marbles = 3 + 9 + 8

Total marbles = 20

Now, we have to calculate the probability of obtaining two blue marbles without replacement.

The probability will be:

P( obtaining two blue marbles without replacement ) = 8 / 20 × 7 / 19

P( obtaining two blue marbles without replacement ) = 56 / 380

P( obtaining two blue marbles without replacement ) = 0.15

Therefore, the probability of obtaining two blue marbles without replacement is equal to 0.15.
