Answer:

3/4 - 5/12 = 4/12 - 5/12 = -1/12

Step-by-step explanation:

Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.

3/4 - 5/12

we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .

3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.

Now let us go to the second part which is the answer minus 5/12

4/12 - 5/12 = (4 - 5)/12 = -1/12

The final answer should be -1/12. This is another error that has been detected.

The correct answer combination should be as follows.

3/4 - 5/12 = 4/12 - 5/12 = -1/12

now we have
-2 times 20.0855=-40.1711

answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)

Calculate the couple moment acting on the steering wheel, and express it as a Cartesian vector.

IRISSAK [1]

The equation for resolving couples will come in place

$Fcos\theta=0\\\ Fsin\theta =0$

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.

<h3>Couple moment and Cartesian vector</h3>

Couple moment:This looks at the product of the forces acting on a body( in this context a steering wheel ) by the perpendicular distance that exist amidst the forces.

Cartesian vector:this is the representation of unit vectors by i and j along the x-axis and the y-axis, respectively.

Therefore, in calculating the <em>couple</em> moment t acting on the steering wheel, the equation for resolving couples will come in place

$Fcos\theta=0\\\ Fsin\theta =0$

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.

Helena wants to paint a box in the shape of a cube with sides that are 18 inches long. what is the surface area that Helena will

yan [13]

Answer:

1944 Inches Squared

Step-by-step explanation:

Surface area Formula for a Cube:

$A = 6a^2$

The "edge", which is also the side, is 18 inches.

$a = 18$

Solve the formula.

$A= 6a^2 = 6(18)^2 = 6 * 18^2\\18^2 = 324\\324 * 6 = 1944\\A=1944$

The cube's surface area should be 1944 square inches.

What is the solution for the equation StartFraction 5 Over 3 b cubed minus 2 b squared minus 5 EndFraction = StartFraction 2 Ove

wolverine [178]

Answer:

The solutions are:

$b=0,\:b=4$

Step-by-step explanation:

Considering the expression

$\frac{5}{3b^3-2b^2-5}=\frac{2}{b^3-2}$

Solving the expression

$\frac{5}{3b^3-2b^2-5}=\frac{2}{b^3-2}$

$\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c$

$5\left(b^3-2\right)=\left(3b^3-2b^2-5\right)\cdot \:2$

$5b^3-10=6b^3-4b^2-10$

$\mathrm{Switch\:sides}$

$6b^3-4b^2-10=5b^3-10$

$6b^3-4b^2-10+10=5b^3-10+10$

$6b^3-4b^2=5b^3$

$\mathrm{Subtract\:}5b^3\mathrm{\:from\:both\:sides}$

$6b^3-4b^2-5b^3=5b^3-5b^3$

$b^3-4b^2=0$

$Using\:the\:Zero\:Factor\:Principle:$ $if\:\mathrm ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

So,

$b=0,b-4=0$

$b=0,b=4$

Therefore, the solutions are:

$b=0,\:b=4$
