Answer: 24 Explanation: You would have to use PEMDAS for this. First, you would multiply -4 x 9 to get -36 then you would multiply that by 2/3 to get -24. Next you would divide -24 by -2 and that would get you a positive 12. Finally you would divide 12 by 1/2 and that would give you 24. Hopefully this makes sense. Heres my work for it too.

Answer:

B. 1,188 cubic units

Step-by-step explanation:

First find the area of the base

A = 1/2b*h (this would only be half the base so our formula would be)

A = b*h (Now enter values)

A = (9)(6)

A = 54 (now plug this into the volume formula)

V = Ab * h

V = (54)(22)

V = 1,188 cubic units

Nick is a great baby sitter.He makes $9 an hour.Julia is an even better babysitter She makes $12 an hour.Julia works 6 hours eac

serg [7]

Answer:

Nick has to work 8 hours

Step-by-step explanation:

Nick makes 9 works x

Julia makes 12 works 6

first find out how much Julia makes you can do that by multiplying 12 by 6 witch = 72

and we know we are trying to find how many hours Nick needs to work to equal Julia so we knew they are equal

so we have 9X=72

we just have to solve...

divide 72 by 9

leaving use with X=8

Geometry help please

lina2011 [118]

Hello!

The equation to find the volume of a cone is

$\pi r^{2} \frac{h}{3}$

r is radius
h is height

Put in the values we know

$3.14 * 9^{2} * \frac{4}{3}$

Square the number

$3.14 * 81 * \frac{4}{3}$

multiply 81 by 3.14

$254.34 * \frac{4}{3}$

Multiply

339.12

The answer is 339.1 cubic inches

Hope this helps!

In ELECTRONICS, the total resistance to the flow of electricity in a circuit is called the impedance, Z. Impedance is represente

Tema [17]

Total impedance of circuit is Z1 + Z2

Here it is important that real numbers we sum with real numbers and complex numbers with complex numbers

Let Zs represent total impedance.

Zs = Z1 + Z2 = 3 + 4i + 5 - 2i = 3 + 5 + 4i - 2i = 8 + 2i

Answer is :

8+2i
