The number of minutes it will take 5 machines to make 15 widgets is 90 minutes

Given that :

The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.

Using the variation protocol defined :

Let :

n = number of widgets made

n = number of widgets made m = number of machines used

n = number of widgets made m = number of machines used t = time taken

Hence, from joint variation :

t α n α 1/m

t = kn/m

Where k = constant of proportionality :

Solving for k

When t = 10, n = 5, m = 15

10 = (k × 5) / 15

15 × 10 = 5k

150 = 5k

k = 150 / 5

k = 30

Equation becomes :

t = 30n/m

Solve for t ;

When m = 5 ; n = 15

t = (30 × 15) / 5

5t = 450

t = 450 / 5

t = 90

Hence, it will take 90 minutes.

David made a triangle with sides 6 cm, 9cm , 12 cm. George wanted to make a triangle bigger in size but similar to that drawn by
SashulF [63]

Step-by-step explanation:

Given :

\triangle ABC \sim \triangle XYZ .△ABC∼△XYZ.

AB = 6\:cm, \:BC = 9 \:cm, CA = 12 \:cmAB=6cm,BC=9cm,CA=12cm

Let \: XY = 10\:cm, \:YZ = x \:cm, \: XZ = y /:cmLetXY=10cm,YZ=xcm,XZ=y/:cm

\frac{AB}{XY} = \frac{BC}{x} = \frac{CA}{y}XYAB=xBC=yCA

\blue {( The \: lengths \:of \: corresponding }(Thelengthsofcorresponding

\blue {sides \:are \: proportional .)}sidesareproportional.)

\implies \frac{6}{10} = \frac{9}{x} = \frac{12}{y}⟹106=x9=y12

i) \implies \frac{6}{10} = \frac{9}{x}i)⟹106=x9

\implies x = \frac{9 \times 10}{6}⟹x=69×10

\implies x = 15\:cm⟹x=15cm

ii) \implies \frac{6}{10} = \frac{12}{y}ii)⟹106=y12

\implies y = \frac{12 \times 10}{6}⟹y=612×10

\implies y = 20\:cm⟹y=20cm

Therefore.,

\red { Value \:of \:x } \green { = 15\:cm }Valueofx=15cm

\red { Value \:of \:y } \green { = 20\:cm }Valueofy=20cm
