rewrite these in increasing order of length: 537 km, 790 dm, 41 cm, 8 mm, 788 m
kompoz [17]

Answer: 8mm,\ 41cm,\ 790dm,\ 788m,\ 537km

Step-by-step explanation:

To solve this problem you must:

1. Write the lenghts given in the problem in the same units.

2. Let's convert all the units to meters. Then:

537 km to m:

(537km)(\frac{1,000}{1km})= 537,000m

790 dm to m:

(790dm)(\frac{1m}{10dm})=79m

41 cm to m:

(41cm)(\frac{1m}{100cm})=0.41m

8 mm to m:

(8mm)(\frac{1m}{1,000mm})=8*10^{-3}m

Now you rewrite them in increasing order:

8mm,\ 41cm,\ 790dm,\ 788m,\ 537km

A rectangular swimming pool is twice as long as it is wide. A small concrete sidewalk surrounds the pool and is a constant 2 fee
Naddika [18.5K]

Answer:

The dimensions of the pool are:

Width: 8.944 feet

Length: 17.888 feet

Step-by-step explanation:

From Geometry, the area of a rectangle (A), measured in square feet, is determined by the following equations:

A = w\cdot l (1)

Where:

w - Width, measured in feet.

l - Length, measured in feet.

If we know that w = x, l = 2\cdot x and A = 160\,ft^{2}, then we get the following second order polynomial:

2\cdot x^{2}-160 = 0 (1)

And we solve the expression for x:

2\cdot x^{2} = 160

x^{2} = 80

x = \sqrt{80}\,ft

x \approx 8.944\,ft

Then, the dimensions of the pool are, respectively:

w \approx 8.944\,ft and l \approx 17.888\,ft

If c = 64-d, what is the value of C when D = -1/6
BabaBlast [244]

The equation c = 64 - d is a linear equation, and the value of c in the equation is 64 1/6

<h3>How to solve the equation?</h3>

The equation is given as:

c = 64 - d

The value of d is given as:

d = -1/6

Substitute -1/6 for d in c = 64 - d

c = 64 - -1/6

Evaluate the difference

c = 64 1/6

Hence, the value of c in the equation is 64 1/6
