Abe real estate is developing 15 solar homes per states. If the cost of each home is estimated at 80,000 what’s the projected co

Soloha48 [4]

Answer:

the Total cost= 1,200,000*number of states

Step-by-step explanation:

Given the cost of each home is $80,000

The number of homes per state are 15

The Total cost of the project is = (Total number of houses per state) * (cost of each house) * (the number of states).

Therefore the total cost =15*80000*Number of states.=1,200,000*number of states

Write an equation of a line through the point (-5, -2) that is perpendicular to the x-axis. State the slope of the line.

zmey [24]

Perpendicular to x axis means then that the euation is x=something
given
(-5,-2)
(x,y)
so x=-5 is da equation

Ef is the median of trapezoid abcd (please explain the answer im so confused lol)

Art [367]

Step-by-step explanation:

Okay, so...

The Median of a trapezoid is directly in the middle. For some weird mathimatical reason you won't ever need to know unless it's on an exam or you become a math major, its midsegment is the average of the top length and the bottom length.

In other words,

EF = ( BC + AD ) / 2

So for part 1, we can use that equation to find x.

$EF = ( BC + AD ) / 2$

Insert known equations.

$4x-18=[(x+12)+(3x-4)]/2$

Simplify within parentheses.

$4x-18=[x+12+3x-4]/2$

$4x-18=[x+3x+12-4]/2$

Add.

$4x-18=[4x+8]/2$

Divide.

$4x-18=2x+4$

Simplify.

$(4x-2x) +(-18+18)=(2x-2x)+(4+18)$

$2x=22$

Divide both sides by 2.

$x=11$

Part 2 is a lot easier now. All we have to do is plug in 11 for x.

$BC =x+12$

$BC = 11+12$

$BC = 23$

$AD = 4x-18$

$AD = 4(11)-18$

$AD = 44-18$

$AD = 26$

$EF = 3x-4$

$EF = 3(11)-4$

$EF = 33-4$

$EF = 29$

Answer:

Part I: x = 11

Part II:

BC = 23
AD = 26
EF = 29
