The first leg of the graph represents Manuel riding his bike for 3 units of time going 5 units distance gradually increasing his speed. The second line segment represents Manuel staying where he his for 4 1/2 units of time. The third represents Manuel going a fast speed back to where he started. I think.

Or the first is him going that distance picking up speed, the second him going a constant speed, and the third him slowing down/speeding up.

HELP! 25 points! I'm really bad at math and need to find out the angle of x

ICE Princess25 [194]

angle CEB and AED are corresponding angles, so they are both are equal

since we already know that CEB is equal to 160, that means that AED is also equal to 160

all you have to do to find the value of x is subtract the 115 from 160, and so you get 45

so, x=45

hope this helps!! :)

A checkers board is eight squares long and eight squares wide. The area of each square is 14 cm². Estimate the perimeter of the

Tamiku [17]

Answer:

Perimeter of the board is 119.7 cm.

Step-by-step explanation:

We are given that,

Area of each square = 14 cm²

i.e. $Side^2=14$

i.e. $Side= \sqrt{14}$

i.e Side = 3.74 cm

So, we get the side of each square is 3.74 cm.

Since, Perimeter of a square = $4a$

→ Perimeter of each square = $4\times 3.74$

→ Perimeter of each square = 14.96 cm

<em>Since, there are 8×8= 64 squares on the board.</em>

Thus, the perimeter of the board = 8 × Perimeter of each square.

i.e. Perimeter of the board = 8 × 14.96

i.e. Perimeter of the board = 119.68 cm

Hence, the perimeter of the board rounded to the tenths is 119.7 cm.
