Answer:

0.5 A

Step-by-step explanation:

Hi,

I believe the question is incomplete. However, as per the information provided:

The simplest way to calculate the Current (unit is Amperage), is understanding the relationship between the three: Power, Voltage and Current.

<em>(Quick Tip: </em><em>W=AV</em><em>; where W -> Watts (Power), A -> Ampere (Current), V -> Volts (Voltage))</em>

Using the formula we calculate the Ampere:

W = A x V

60 = A x 120

60/120 = A (We divide the equation be 120)

0.5 = A  (Simply reduce the fraction 60/120  = 1/2 = 0.5)

Answer:

C) $3.77

Step-by-step explanation:

  • $2.80 + $0.10 = $2.90

  • Turn 30% into 0.30 by moving the decimal point (percentage sign) 2 places to the left.

  • To solve 30% of $2.90  →   0.30 x 2.90 = 0.87

  • Finally  $2.90 + $0.87 = $3.77

Answer:

24.08

Step-by-step explanation:

We use the Pythagorean theorem and we get (16)^2 + (18)^2 = (x)^2

256 + 324 = x^2

x^2 = 580

x is about 24.08.

Hello.

Taking a look at our screenshot provided, we can conclude that we need to find the missing angle degree out of 90 degrees, as we are dealing with a right angle.

Let's set this up as an Algebraic formula and solve for the variable;
5x + 15 + 50 = 90

First, let's combine like-terms (15 and 50).

5x + 65 = 90

Now, isolate our variable by subtracting 65 from each side of the equation.

90 - 65 = 25
65 - 65 = 0

5x = 25

Now, divide both sides by 5 to solve for x, our missing angle degree.

x = 5

Your answer is A.) 5

I hope this helps!
