vovikov84 [41]

Complete question :

A construction crew built 1/2 miles of road in 1/8 days. What is the unit rate in miles per day? Write your answer in simplest form.

Answer:

3 miles per day

Step-by-step explanation:

Given that:

1/2 miles of road takes 1/8 days

Unit Rate in miles per day :

Miles of road built / number of days taken

1/2 miles ÷ 1/8 days

1/2 * 8/1

= (1*8) / (2*1)

= 8/2

= 4

Unit Rate = 4 miles per day

The distance dd is 11 mm. What is the perimeter of the figure? Round to the nearest tenth.

Kisachek [45]

Answer:

P = 157.1 mm

Step-by-step explanation:

The perimeter of the figure = Circumference of circle + perimeter of square

We have, d = 11

⇒ Radius = 11 mm

Side of square = 22 cm

So,

$P=2\pi \times 11+4\times 22\\\\P=157.11\ mm\\\\or\\\\P=157.1\ mm$

So, the perimeter of the figure is equal to 157.1 mm.

Julia used 1 foot square stone tiles to make a patio. She laid the tiles in a square, 7 tiles wide by 7 tiles long. What is the

marshall27 [118]

Answer: $49\ ft^2$

Step-by-step explanation:

The formula that is used to calculate the area of a square is this one:

$A=s^2$

Where "s" is the side lenght of the square

You know that Julia used 1 foot square stone tiles, then each side lenght of the this tiles is:

$s_{tile}=\sqrt{1\ ft^2}\\\\s_{tile}=1\ ft$

Since Julia laid 7 tiles wide by 7 tiles long, the side lenght of the new patio is:

$s_{patio}=7(1\ ft)\\\\s_{patio}=7\ ft$

Therefore its area is:

$A_{patio}=(7\ ft)^2\\\\A_{patio}=49\ ft^2$
