Calculate the length of DE.

Mathematics
1 answer:
CaHeK987 [17]3 years ago
8 0

set up the proportion, cross multiply, and solve for the missing length.

\frac{BA}{BE} = \frac{DC}{DE}

\frac{6}{3} = \frac{9}{DE}

6(DE) = 3(9)

DE = \frac{3(9)}{6} = \frac{9}{2} = 4.5

Answer: 4.5

4. a) A load of 1000N can be lifted by applying an effort of
miv72 [106K]

Step-by-step explanation:

load=1000N

effort=250N

load arm=25cm

effort arm=?

Now,

E×E.D=L×L.D

250×E.D=1000×25

E.D=1000×25÷250

E.D=100cm

therefore,effort arm is 100cm.

find the equation of a line that goes through the point (2,-3) and is perpendicular to the line y= -2/5x+6
GarryVolchara [31]
Find the negative reciprocal of the given line's slope in order to determine what the slope of the line will be.

-2/5 -> -5/2 -> 5/2

Your line now looks like this: y = 5/2x + b

Now, substitute the given point into the y and x variables and solve for b.

   y = 5/2x + b
  -3 = 5/2(2) + b
  -3 = 5 + b
  -8 = b

You are now done. The line is y = 5/2x - 8.
