Given: AKLM is a trapezoid, AK=13 LM=14, KL=5, AM=20 Find: h

sveta [45]

The height of the trapezoid is $h=11.2$

Explanation:

AKLM is a trapezoid.

The measurements of the trapezoid are AK=13, LM=14, KL=5, AM=20

We need to find the height of the trapezoid.

Let M' be a point on AM that is 5 units toward point A from M.

Let B be a point on AM such that KB⊥AM. Let x = AB; then BM' = 15 -x.

Using Pythagorean theorem, we have,

$x^{2}+h^{2}=13^{2}$ --------(1)

$(15-x)^{2}+h^{2}=14^{2}$

$225-30x+x^{2} +h^{2}=14^{2}$ -----------(2)

Subtracting the two equations, we have,

$\left(225-30 x+x^{2}+h^{2}\right)-\left(x^{2}+h^{2}\right)=196-169$

Simplifying, we get,

$225-30x=27$

Subtracting both sides of the equation by 225, we get,

$30x=198$

Dividing by 30, we get,

$x=6.6$

Substituting $x=6.6$ in the equation $x^{2}+h^{2}=13^{2}$ , we get,

$(6.6)^{2}+h^{2}=169$

$43.56+h^2=169$

$h=\sqrt{125.44}$

$h=11.2$

Thus, the height of the trapezoid is $h=11.2$

How many 1/3 cubes does it take to fill a box with a width of 2 2/3 inches length 3 1/3 inches and height 2 1/3

Paladinen [302]

Answer:

560

Step-by-step explanation:

I assume 1/3 is the side length of the cubes.

There's two ways to solve this:

1. Find the volume of the box, then divide by the volume of the cubes.

Or 2. Find the number of cubes per each side length, the find the volume in terms of cubes.

Either way, we need to convert the mixed fractions to improper fractions.

W = 2⅔ = (2×3+2)/3 = 8/3 inches

L = 3⅓ = (3×3+1)/3 = 10/3 inches

H = 2⅓ = (2×3+1)/3 = 7/3 inches

Using the first method, the volume of the box is:

V = (8/3 in) (10/3 in) (7/3 in) = 560/27 in³

The volume of a cube is:

V = (1/3 in)³ = 1/27 in³

So the number of cubes in the box is:

(560/27 in³) / (1/27 in³) = 560

Using the second method, the cubes per each side of the box is:

W = (8/3 in) / (1/3 in) = 8

L = (10/3 in) / (1/3 in) = 10

H = (7/3 in) / (1/3 in) = 7

So the number of cubes is:

8 × 10 × 7 = 560

G=1/2(w+40) solve for w

WITCHER [35]

Answer: W=6g-40

Step-by-step explanation:

g= 1/6(w+40)

Multiply each part of the equation by six

6g=w+40

Subtract forty from each part of the equation

W=6g-40
