Answer:

Step-by-step explanation:

Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state: $V=IR$

So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.

The pair 4 and 8 ohms are parallel, so we solve:

$R_{T}=\frac{1}{R_{1}}+\frac{1}{R_{2}}$

$\frac{1}{R_{T}}=\frac{1}{4}+\frac{1}{8}=\frac{8+4}{32}=\frac{12}{32}=\frac{3}{8}$

Which is, $R_{T}=frac{8}{3}$

Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:

$R=3+\frac{8}{3}=\frac{9+8}{3}=\frac{17}{3}=5.67 ohm$

Now that we have the total resistance of the circuit, we use the Ohm's Law:

$V=IR\\V=(0.6A)(5.67ohm)=3.4 Volt$

Therefore, the right answer is B.

A decimal number changed to 23.7 after it was rounded. Give a decimal number that is less than 23.7 and another that is greater

mrs_skeptik [129]

Two possible answers are:

23.65 and 23.72.

Explanation:

For the first number, 23.65, we are rounding to the tenths place. 23.65 itself is smaller than 23.7. Looking behind the tenths place, the digit behind it is 5. This means we round the tenths place up; this becomes 23.7.

23.72 is larger than 23.7. We will round it to the tenths place as well. Looking behind the tenths place, we have a 2; this means we "round down." This means leave the 7 as it is and drop the other digits behind it. This gives us 23.7.

For a circle with a radius of 6 feet, what is the measurement of the central angle (in degrees) that intercepts an arc

geniusboy [140]

Answer: The central angle measures 135 degrees

Step-by-step explanation: We have been given an arc with length 9pi/2 feet and a radius of 6 feet. The arc is shown in the attached diagram (please see attachment). The central angle subtended by this arc is at point O and has been labeled angle X.

So if the diagram shows arc AB with length 9pi/2 and radius AO with length 6, we can use the formula to compute “Length of an arc” to arrive at the missing angle.

Length of an arc = X/360 x 2pi x radius

Substituting for the known values, our formula can now be re-written as

9pi/2 = X/360 x 2pi x6

By cross multiplication we now have

9pi/2pi x 6 = 2X/360

We simplify as much as possible by dividing all like terms, hence pi divides pi on the left side of the equation. Also 2 divides 360 on the right side of the equation.We now arrive at,

9/12 = X/180

Simplify even further and we have

3/4 = X/180

By cross multiplication we now have

(3 x 180)/4 = X

540/4 = X

135 = X

Therefore the central angle that intercepts the arc measures 135 degrees.
