Answer:

Number is 8 - 6i.

Step-by-step explanation:

Given : (-2 − 2i) + (10 − 4i).

To find : Write as a complex number in standard form.

Solution : We have given (-2 − 2i) + (10 − 4i).

We can write it as -2 -2i + 10 -4i

Combine like terms

-2 +10 - 2i -4i.

8 - 6i.

Therefore, Number is 8 - 6i.

Sam is planting a garden that measures

nikitadnepr [17]

Answer:

63.7 feet

Step-by-step explanation:

We can re-write the width and the length both as rational numbers:

- Width: $w=6.5=\frac{65}{10}$

- Length: $L=9.8=\frac{98}{10}$

So now we can find the area of the garden by multiplying width and length:

$A=wL=\frac{65}{10}\cdot \frac{98}{10}=\frac{65\cdot 98}{10\cdot 10}=\frac{6370}{100}=63.7$

Answer:

480

Step-by-step explanation:

The probability she will roll 2 odd numbers is 12/50 (the number of odd rolls over the total). This simplifies to 6/25

Multiply the probability times the total number of rolls to get a good estimate of the number of rolls that till be odd odd

6/25 * 2000 =480

4 more than one third of a number n is 6. An equation is? The solution is n =?

harkovskaia [24]

Answer:

$\frac{1}{3}$ n + 4 = 6

Step-by-step explanation:

Given problem:

4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number = ?

Solution:

let the number = n

So, 4 more than one third of a number;

One third of n = $\frac{1}{3}$ n

4 more;

$\frac{1}{3}$ n + 4

is 6;

$\frac{1}{3}$ n + 4 = 6 (equation of the expression)

Let us now solve the equation:

$\frac{1}{3}$ n + 4 = 6

$\frac{1}{3}$ n = 6 - 4

$\frac{1}{3}$ n = 2

n = 6
