Answer:

a = -6 and b = 1

Step-by-step explanation:

We have given a complex number.

i-6

We have to find the value of a and b using general form of complex numbers.

The general form of complex numbers is a+bi.

given complex number can be written as:

-6+1i

Comparing with general form , we have

a = -6 and b = 1 which is the answer.

9/5C + 32 =59<br><br> I'm stuck on how to do this .. please help

Harlamova29_29 [7]

Answer:

C= 15

Step-by-step explanation:

$\frac{9}{5} C + 32 = 59$

subtracting 32 from both sides

$\frac{9}{5}C = 59 -32$

$\frac{9}{5} C = 27$

Dividing both sides by 9/ 5

$C = 27 \times \frac{5}{9}$

$C = 3 \times 5$

$C = 15$

12 one half times one nine

pshichka [43]

Answer:

$1\frac{7}{18}$ or one seven eighteenths

Step-by-step explanation:

we know that

12 one half times one nine is the same that multiply 12 one half by one nine

$(12\frac{1}{2})(\frac{1}{9})$

Convert mixed number to an improper fraction

$12\frac{1}{2}=12+\frac{1}{2}=\frac{12*2+1}{2}=\frac{25}{2}$

substitute

$(\frac{25}{2})(\frac{1}{9})=\frac{25}{18}$

Convert to mixed number

$\frac{25}{18}=\frac{18}{18}+\frac{7}{18}=1\frac{7}{18}$

therefore

12 one half times one nine is one seven eighteenths

A rocket moves through outer space at 10,500 m/s. At this rate how much time would be required to travel the distance from Earth

Orlov [11]

Answer:

The answer is around 27.63 seconds.

Step-by-step explanation:

1 km equals 1000 meters so we have to multiply 10,500 and 1,000 which would equal 10,500,000 km. 10,500,000 divided by 380,000 which is around 27.63 seconds.
