5 0

Step-by-step explanation:

so, all 3 pieces together are 20 inches.

therefore,

x + 4x + 5x = 20

10x = 20

x = 2

so, the first piece is 2 inches long.

the second piece is 4×2 = 8 inches long.

the third piece is 5×2 = 10 inches long.

What is the abscissa of the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)?

Masteriza [31]

Answer:

Midpoint is (3.5, 2)

Step-by-step explanation:

the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)

To find midpoint of two end points we use formula

$(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

(5, 2) , x1 = 5 and y1= 2

(2,2), x2=2 and y2= 2

Plug in all the values and find the midpoint using the formula

$(\frac{5+2}{2},\frac{2+2}{2})$

$(\frac{7}{2},\frac{4}{2})$

(3.5, 2)

So midpoint is (3.5,2)

shepuryov [24]

Answer:

A) $\sqrt{52}$

Step-by-step explanation:

$a^{2} +b^{2} =c^{2}$

$4^{2} +6^{2} =c^{2}$

16+36= $c^{2}$

$\sqrt{52} =\sqrt{c^{2}}$

$\sqrt{52} =c$
