Answer: x = 5

Step-by-step explanation:

We can set up an equation to solve for x:

3x  + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5

X=5

19-4=15
15/3=5

Or

5 x 3 = 15
15 + 4 = 19

PLEASE HELP! Given: △MNO m∠M=45°, m∠O=30° MN=6 Find: NO, MO.
zubka84 [21]

Answer:

NO = 8.48 units, MO = 11.59 Units

Step-by-step explanation:

∠M = 45°

∠O = 30°

∠N = 180-(45+30)

∠N = 105°

MN=6 = o

NO = m

MO = n

From sine rule

\frac{sinM}{m}=\frac{sinN}{n}=\frac{sinO}{o}

\\\Rightarrow \frac{sinO}{o}=\frac{sinM}{m}\\\Rightarrow m=\frac{sinM}{\frac{sinO}{o}}\\\Rightarrow m=\frac{sin45}{\frac{sin30}{6}}\\\Rightarrow m=8.48

\frac{sinO}{o}=\frac{sinN}{n}\\\Rightarrow n=\frac{sinN}{\frac{sinO}{o}}\\\Rightarrow n=\frac{sin105}{\frac{sin30}{6}}\\\Rightarrow n=11.59

∴ NO = 8.48 units, MO = 11.59 Units

What is the slope of a Line that goes through (1,0) and (5,3)<br><br> 3/4<br> 4/3<br> 3<br> 4
andre [41]

To find the slope(m), you use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}   And plug in the two points

(x₁ , y₁) = (1, 0)

(x₂ , y₂) = (5, 3)

m=\frac{y_2-y_1}{x_2-x_1}  

m=\frac{3-0}{5-1}

m=\frac{3}{4}

g If the quantity of helium in a weather balloon in increased by a factor of 5 at constant temperature and pressure, by how much
choli [55]

Answer:

Increase by 5 times

Step-by-step explanation:

Given that from the ideal gas law;

PV = nRT

P= pressure

V= volume

n= number of moles

R= gas constant

T = temperature

It the follows that;

V= nRT/P

When the number of moles (quantity of helium) is increased by a factor of 5 while temperature and pressure remain constant, we can write;

PV = 5nRT

V = 5nRT/P

Hence the volume increases by a factor of 5.
