By selling a printer at Rs 15000 and Rs 18000, some lass and some profit are happened respectively. If the loss is one forth of

maksim [4K]

Answer:

Loss= x

profit=y

x=1/4y

4x=y

Let cost = c

c-x= 15000

c+4x=18000

c+4x-(c-x)=18000-15000

5x=3000

x=600

c-x=15000

c-600=15000

c=15600

c+4x=18000

c+2400=18000

c=15600

Cost= Rs15600

The surface area of a rectangular prism is 250 cm 2. If its height is 10 centimeters, and its width is 5 centimeters, what is it

Minchanka [31]

Answer:

$V=250\ cm^{3}$

Step-by-step explanation:

step 1

Find the length of the base L

we know that

The surface area of a rectangular prism is equal to

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

substitute

$SA=2(LW)+2(L+W)H$

we have

$W=5\ cm$

$H=10\ cm$

$SA=250\ cm^{2}$

substitute in the formula and solve for L

$250=2(5L)+2(L+5)10$

$250=10L+20L+100$

$30L=250-100$

$L=5\ cm$

step 2

Find the volume of the rectangular prism

The volume is equal to

$V=(LW)H$

we have

$W=5\ cm$

$L=5\ cm$

$H=10\ cm$

substitute

$V=(5*5)*10=250\ cm^{3}$

Will give brainlist**** What is the slope-intercept equation for the cost of a sub at Fred’s Sub Shop?

Anuta_ua [19.1K]

Answer:

c)y = 5x

Step-by-step explanation:

The intercept is where the lines crosses the y axis

It crosses at (0,0), so the y intercept is 0

(2,10) (4,20) are two points on the line

We can find the slope by using

m = (y2-y1)/(x2-x1)

(20-10)/(4-2)

10/2

The slope is 5

The slope intercept form of the equation is y = mx +b

y= 5x+0

y= 5x
