3 feet of snow fell in 1 2/3 hours. What was that rate in inches per hours?

dalvyx [7]

Answer:

21 $\frac{3}{5}$ in/hr

Step-by-step explanation:

Distance of snow fall = 3ft

Time taken = 1 $\frac{2}{3}$ hrs

Unknown:

Rate of snowfall = ?

Solution:

The rate of the snowfall is the same as the speed of the fall;

Rate of snowfall = $\frac{distance of snowfall}{time}$

Convert the ft to inches;

1ft = 12inches

3ft = 3 x 12 = 36inches

Input the parameters and solve;

Rate of snowfall = $\frac{36}{\frac{5}{3} }$ = 36 x $\frac{3}{5}$ = 21 $\frac{3}{5}$ in/hr

The area of two similar triangles are 50dm^2 and 32dm^2. The sum of their perimeters is 117dm. What us the perimeters of each of

Kay [80]

Answer:

Perimeter of one triangle is 65 dm

Perimeter of other triangle is 52 dm

Step-by-step explanation:

Please remember the concept

If sides are in the ratio of a:b

Then the area in the ratio of $a^{2} :b^{2}$

It is given sum of their perimeter is 117.

Let the small triangle has perimeter as x.

So, perimeter of big triangle is 117-x.

So, we can set up equation as

$\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }$

Cross multiply

50(117-x)^2 =32x^2

Expand the left side

50 $(13689 -234x+x^{2} )$ = $32x^{2}$

Distribute the left side

684450-11700x+ $50x^{2}$ = $32x^{2}$

Subtract both sides $32x^{2}$ and rewrite it $18x^{2} -11700x+684450=0$

Solve this quadratic for x.

Divide both sides of the equation by 18 to simplify.

$x^{2}$ -650 x+38025=0

Now, if possible let's factor

Find two integers whose multiplication is 38025 but adds to -650.

-65 and -585 works.

So, we can rewrite it as

(x -65)(x-585) =0

Solve them using zero product property

x=65, x=585

So, x=65 works here.

So, perimeter of one triangle is 65 dm

Perimeter of other triangle is 117-65= 52 dm
