Solve the following equation. Round solution to the tenths place. 29 = с/7.2 C =

expeople1 [14]

Answer:

c = 208.8

Step-by-step explanation:

a. $\frac{c}{7.2} =29$ To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.

b. $\frac{c}{7.2} =29$ You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.

c: $c = 29 * 7.2$ Then, multiply 7.2 by 29. (The * symbol means multiply)

d. c. = 208.8 The answer is 208.8, which is rounded to the tenths place.

Hope this helps! I tried to explain it in detail. :)

Determine the currents in the picture

Evgesh-ka [11]

Answer:

The value of currents are $I_1=0A$ , $I_2=1A$ and $I_3=1A$ .

Step-by-step explanation:

The Ohm's law states that

$V=IR$

It is given that the V₁=3V and V₂=4V.

In a parallel circuit:

→ Voltage is same in each component

→ Sum of the currents equals to the total current that flows.

$I_2=I_1+I_3$ .... (1)

Equation for first loop is,

$V_1=4I_1+3I_2$

$3=4I_1+3I_2$ ..... (2)

Equation for second loop is,

$V_2=1I_3+3I_2$

$4=1I_3+3I_2$ ..... (3)

On solving (1), (2) and (3) we get

$I_1=0$

$I_2=1$

$I_3=1$

Therefore the value of currents are $I_1=0A$ , $I_2=1A$ and $I_3=1A$ .

Apply the distributive property to create an equivalent expression.

weqwewe [10]

Step-by-step explanation:

$\text{The distributive property:}\ a(b+c)=ab+ac\\\\\dfrac{1}{2}(10x+20y+10z)=\dfrac{1}{2\!\!\!\!\diagup_1}\cdot10\!\!\!\!\!\diagup^5x+\dfrac{1}{2\!\!\!\!\diagup_1}\cdot20\!\!\!\!\!\diagup^{10}y+\dfrac{1}{2\!\!\!\!\diagup_1}\cdot10\!\!\!\!\!\diagup^5z\\\\=5x+10y+5z$
