Answer:

smaller piece length = 2.333 and

larger piece length = 4.666

Step-by-step explanation:

It is given that,

21 A stick 7 inches long is broken into two pieces, so that one piece is twice as long as the other one.

<u>To find the length of two pieces</u>

Le x be the length of smaller part of piece.

Then the length of larger piece = double the smaller piece = 2 * x = 2x

We have total length = 7 inches

Therefore we can write,

x + 2x = 7

3x = 7

x = 7/3 = 2.333

2x = 2.333 * 2 = 4.666

Therefore smaller piece length = 2.333 and

larger piece length = 4.666

Answer:

2.33 inches and 4.66 inches

Step-by-step explanation:

2x+x=7 or 3x=7

divide by three and x =2.33

that's for the first one and the second one is twice the size so it'll be 4.66 inches

A monument in the shape of a right triangle sits on a rectangular pedestarl that is 7 meters high by 16 meters long. The longest
Minchanka [31]

Answer: 70 meters

Step-by-step explanation:

Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.  

Replacing with the values given:  

65^2 = 16^2 + x^2  

4,225 = 256 + x^2

4,225-256 = x^2

3,969=x^2

√3,969 =x

63=x

We have calculated the missing side of the triangle, now we have to add the height of the rectangle:

63 +7 =70 meters

Feel free to ask for more if needed or if you did not understand something.
