For 4 copies, the total cost for preparing and printing will be the same.

Step-by-step explanation:

Let,

p be the number of pages

Company A;

Charges of preparing = $6

Charges of per page print = $2.50

A(p)= 2.50p + 6 Eqn 1

Company B;

Charges of preparing = $4

Charges of per page print = $3

B(p)= 3p + 4 Eqn 2

For equaling the cost;

A(p) = B(p)

$2.50p+6=3p+4\\2.50p-3p=4-6\\-0.50p=-2$

Dividing both sides by -0.50

$\frac{-0.50p}{-0.50}=\frac{-2}{-0.50}\\p=4$

For 4 copies, the total cost for preparing and printing will be the same.

The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length

Mademuasel [1]

Answer:

10.2 inches

Step-by-step explanation:

we know that

In this problem we have two cases

First case

The given lengths are two legs of the right triangle

$a=12\ in, b=15\ in$

Applying the Pythagoras Theorem

Find the length of the hypotenuse

$c^{2}=a^{2} +b^{2}$

substitute

$c^{2}=12^{2} +15^{2}$

$c^{2}=369$

$c=19.2\ in$

Second case

The given lengths are one leg and the hypotenuse

$a=12\ in, c=15\ in$

Applying the Pythagoras Theorem

Find the length of the other leg

$b^{2}=c^{2} - a^{2}$

substitute

$b^{2}=15^{2} - 12^{2}$

$b^{2}=81$

$b=9\ in$

Find the difference between the two possible lengths of the third side of the triangle

$19.2-9=10.2\ in$

Solve for X. Show your work.

Irina18 [472]

Answer:

x=9

Step-by-step explanation:

since the location of 4x+2 and 7x-25 is across from each other that means that they are equal to each other so you have to set them equal to each other by doing 4x+2=7x-25 then you add like terms you add 25 and 2 together which gives you 27 and the equation will look like 4x+27=7x and then you subtract 4x from 7x which gives you 3x and u get the equation 27=3x now you divide 27 by 3 and get 9 so the equation will be x=9

What is the mechanical advantage of a hockey stick that is gripped at point D and hits the puck at point B?

RideAnS [48]

Answer:

Mechanical advantage = Effort distance/Resistance distance

Effort distance = D - Fulcrum = 0.5 m

Resistance distance = A - Fulcrum = 2.0 m

Then,

Mechanical advantage = 0.5/2 = 0.25

Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.

Find the point P along the directed line segment from point A(-16,-8) to point B(0,-17) that divides the segment in the ratio 7

bonufazy [111]

Answer: P(-7.38,-12.85)

Steps:

Draw the directed line in a chart, including points A and B.

Look for the x coordinate of P:

the distance |B-A| along the x coord is |0-(-16)|=16

we are looking for a proportion of 7/13 of that:

the x coord of P is 16*7/13 to the right of -16, or -16+8.62= -7.38

Look for y coordinate of P:

the distance |B-A| along the y coord is |-17-(-8)|=9

we are looking for a proportion of 7/13 of that:

the y coord of P is 9*7/13 down from -8, or -8-4.85= -12.85

so the point P is P(-7.38,12.85)
