Mathematics
1 answer:
Norma-Jean [14]3 years ago
5 0

Answer:

(2,1,0)

Step-by-step explanation:

3x+3y+6z=9

3(2)+3(1)+6(0)=9

6+3+0=9

6+3=9

9=9

x+3y+2z=5

x(2)+3(1)+2(0)=5

2+3+0=5

2+3=5

5=5

3x+12y+12z=18

3(2)+12(1)+12(0)=18

6+12+0=18

6+12=18

18=18

If the measure of a central angle is 213 degrees, then the measure of the arc it intercepts is
Leto [7]

Answer:

\Delta s = \frac{71\pi}{60}\cdot r

Step-by-step explanation:

Let r be the radius of the circle, the measure of the arc is equal to:

\Delta s = \frac{213^{\circ}}{360^{\circ}}\cdot 2\pi \cdot r

\Delta s = \frac{71\pi}{60}\cdot r

Four resistors are connected in series such that their total resistance is 50ohm . If the resistance of resistors is 5 ohm , 10o
Katyanochek1 [597]
<h2>Answer:</h2>

\boxed{R_{4}=20\Omega}

<h2>Step-by-step explanation:</h2>

If resistors are in series, so the current  I is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance  of series combination and the four resistors as follows:

R_{eq}=R_{1}+R_{2}+R_{3}+R_{4}

R_{eq} is the total resistance 50\Omega. Moreover:

R_{1}=5\Omega \\ R_{2}=10\Omega \\ R_{3}=15\Omega

Therefore:

50=5+10+15+R_{4} \\ \\ R_{4}=50-(5+10+15) \\ \\ R_{4}=50-30 \\ \\ \boxed{R_{4}=20\Omega}

geniusboy [140]

Answer: 4.9

Step-by-step explanation:

You are trying to find the density

So you divide the mass by the volume

Mass: 37 grams

Volume: 7.5 liters

37 grams/ 7.5 liters = 4.9
