Berry Boulevard is 4 4/5 Miles long.There are two traffic lights on Berry Boulevard every 2/5 mile after the street begins .Ther
Gwar [14]

Answer: There are 24 traffic lights on Berry Boulevard.

Step-by-step explanation:

Since we have given that

Total length of road = 4\dfrac{4}{5}=\dfrac{24}{5}\ miles

Number of roads on every \dfrac{2}{5}\ mile = 2

So, According to unitary method,

In every \dfrac{2}{5}\ mile, number of roads = 2

In every 1 mile, number of roads = \dfrac{5}{2}\times 2=5

So, in every \dfrac{24}{5}\ miles,  the number of roads = \dfrac{24}{5}\times 5=24

Hence, there are 24 traffic lights on Berry Boulevard.

Two boards, one four inches wide and the other six inches wide, are nailed together to form an X. The angle at which they cross
Sunny_sXe [5.5K]

Answer:

The area of the unpainted region on the four inch board = 160·√3 in.²

Step-by-step explanation:

Here we have that the boards are crossing each other on their flat sides Therefore, when the boards are separated, the area of the unpainted region is the area of a parallelogram

The dimensions of the formed parallelogram are;

Interior angles = 60° and 120° (adjacent angles of a parallelogram)

Height, h of parallelogram formed = 4 inches

From the angle of crossing of the parallelogram, we have;

Angle between the width or perpendicular cross section of the 6 inches board and the angle of crossing of the two boards = 90° - 60° = 30°

Therefore, length of base, b of the parallelogram formed by the unpainted region is given as follows;

b = \frac{60}{cos(30)}  = 40\cdot \sqrt{3} \ inches

Therefore, the area of the parallelogram = b × h = 4 × 40·√3 = 160·√3 in.²

Hence, the area of the unpainted region on the four inch board = 160·√3 in.².

Kenny buys 4 1liter bottles of water how many millileters of water does Kenny buy
kenny6666 [7]
Kenny bought 4 1liter bottles of water

1liter is equal to 1,000 milliliters (milli means 1,000)

What that means is that in each bottle of water that he purchased, he has 1,000 milliliters

He has 4 bottles, so we simply take

4(bottles) x 1,000(amount of water in each bottle)

4 x 1,000 = 4,000 milliliters
