What is the perimeter of a rectangle with sides 2/3x+10 and 1/3x+5
gogolik [260]

Answer:

The perimeter of the rectangle  is 2x+ 30

Step-by-step explanation:

Sides of the rectangle are 2/3x+10 and 1/3x+5

Now, Perimeter of the Rectangle = 2(Length + Breadth)

Here, sum of the sides = (\frac{2}{3}x + 10 )  + (\frac{1}{3}x + 5 )  = (\frac{2}{3}x +\frac{1}{3}x  )  + ( 10+ 5 )

adding like terms with like terms, we get

(\frac{2x + x}{3})  + 15 = \frac{3x}{3}  + 15

Hence, Sum = (x + 15)

Now,  2(Length + Breadth)  = 2(x+15) = 2x + 30

hence, the perimeter of the rectangle  = 2x+ 30

A parachute speed during a free fall reaches117 miles per hour What is the speed in feet per second At the speed how many feet w
qwelly [4]

Answer:

Speed is 171.6 ft/s and distance is 1716 feet

Step-by-step explanation:

Given that,

The speed of a parachute = 117 miles per hour.

1 mph = 1.47 ft/s

117 mph = 171.6 ft/s

We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,

d = vt

d=171.6\ ft/s\times 10\ s\\\\=1716\ \text{feet}

Hence, this is the required solution.
