Answer:

<em><u>x=-4</u></em>

<em><u> x=14</u></em>

Step-by-step explanation:

<u><em>Absolute Value Equation entered :</em></u>

<u><em>      3|5-x|+2=29 </em></u>

<u><em></em></u>

<u><em>Step by step solution :</em></u>

<u><em>STEP</em></u>

<u><em>1</em></u>

<u><em>:</em></u>

<u><em>Rearrange this Absolute Value Equation</em></u>

<u><em>Absolute value equalitiy entered</em></u>

<u><em>      3|-x+5|+2 = 29 </em></u>

<u><em></em></u>

<u><em>Another term is moved / added to the right hand side.</em></u>

<u><em></em></u>

<u><em>      3|-x+5| = 27 </em></u>

<u><em></em></u>

<u><em>STEP</em></u>

<u><em>2</em></u>

<u><em>:</em></u>

<u><em>Clear the Absolute Value Bars</em></u>

<u><em>Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.</em></u>

<u><em></em></u>

<u><em>The Absolute Value term is 3|-x+5|</em></u>

<u><em></em></u>

<u><em> For the Negative case we'll use -3(-x+5) </em></u>

<u><em></em></u>

<u><em>For the Positive case we'll use 3(-x+5) </em></u>

<u><em></em></u>

<u><em></em></u>

<u><em>STEP</em></u>

<u><em>3</em></u>

<u><em>:</em></u>

<u><em>Solve the Negative Case</em></u>

<u><em>      -3(-x+5) = 27 </em></u>

<u><em></em></u>

<u><em>     Multiply</em></u>

<u><em>      3x-15 = 27 </em></u>

<u><em></em></u>

<u><em>     Rearrange and Add up</em></u>

<u><em>      3x = 42 </em></u>

<u><em></em></u>

<u><em>     Divide both sides by 3</em></u>

<u><em>      x = 14 </em></u>

<u><em></em></u>

<u><em></em></u>

<u><em>STEP</em></u>

<u><em>4</em></u>

<u><em>:</em></u>

<u><em>Solve the Positive Case</em></u>

<u><em>      3(-x+5) = 27 </em></u>

<u><em></em></u>

<u><em>     Multiply</em></u>

<u><em>      -3x+15 = 27 </em></u>

<u><em></em></u>

<u><em>     Rearrange and Add up</em></u>

<u><em>      -3x = 12 </em></u>

<u><em></em></u>

<u><em>     Divide both sides by 3</em></u>

<u><em>      -x = 4 </em></u>

<u><em></em></u>

<u><em>     Multiply both sides by (-1)</em></u>

<u><em>      x = -4 </em></u>

<u><em>     Which is the solution for the Positive Case</em></u>

<u><em></em></u>

<u><em>STEP</em></u>

<u><em>5</em></u>

<u><em>:</em></u>

<u><em>Wrap up the solution</em></u>

<u><em> x=14</em></u>

<u><em> x=-4</em></u>

A steel hex nut has two regular hexagonal bases and a cylindrical hole with a diameter of 1.6 centimeters through the middle. Th
Kisachek [45]

Answer:

Subtracting the volume of the cylinder from the volume of the prism, the volume of metal in the hex nut to the nearest tenth is 23.6 cm^3 (second option)

Step-by-step explanation:

Diameter of the cylinder: d=1.6 cm

Apothem of the hexagon: a=2 cm

Assuming the thickness of the steel hex nut: t=2 cm

Volume of metal in the hex nut: V=?

V=Vp-Vc

Volume of the prism: Vp

Volume of the cylinder: Vc


Prism:

Vp=Ab h

Ab=n L a / 2

Number of the sides: n=6

Side of the hexagon: L

Height of the prism: h=t=2 cm

Central angle in the hexagon: A=360°/n

A=360°/6

A=60°

tan (A/2)=(L/2) / a

tan (60°/2)=(L/2) / (2 cm)

tan 30° = (L/2) / (2 cm)

sqrt(3)/3=(L/2) / (2 cm)

Solving for L/2:

(2 cm) sqrt(3)/3 = L/2

2 sqrt(3)/3 cm = L/2

Solving for L:

2 (2 sqrt(3)/3 cm)=L

4 sqrt(3)/3 cm = L

L=4 sqrt(3)/3 cm

Ab=n L a / 2

Ab=6 (4 sqrt(3)/3 cm)(2 cm) / 2

Ab=24 sqrt(3)/3 cm^2

Ab=8 sqrt(3) cm^2

Vp=Ab h

Vp=(8 sqrt(3) cm^2)(2 cm)

Vp=16 sqrt(3) cm^3

Vp=16 (1.732) cm^3

(1) Vp=27.712 cm^3


Cylinder:

Vc=(π d^2/4) h

π=3.14

d=1.6 cm

Height of the cylinder: h=t=2 cm

Vc=[3.14 (1.6 cm)^2 / 4] (2 cm)

Vc=[3.14 (2.56 cm^2) / 4] (2 cm)

Vc=(2.0096 cm^2) (2 cm)

Vc=4.019 cm^3


V=Vp-Vc

V=27.712 cm^3 - 4.019 cm^3

V=23.693 cm^3

V=23.6 cm^3

What is the interest rate if a principal of $213 earns $42.60 in interest in five years?
vladimir1956 [14]

Answer:

Step-by-step explanation:

Interest = P*r*t/100

42.60=\frac{213*r*5}{100}\\\\213*r*5=42.60*100\\\\213*r*5=4260\\\\r=\frac{4260}{5*213}\\\\r=4

Rate of interest = 4%
