1. A sphere is sliced so that the cross section does not intersect the center of the sphere.
stich3 [128]
1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,

A = L*H = 12*6 = 72 cm^2

3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).

Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2

4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.

Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm

• What is the solution to 5x+ 20 = 7(x+2)?
o-na [289]

For this case we must find the solution of the following equation:

5x + 20 = 7 (x + 2)

Applying distributive property on the right side of the equation we have:

5x + 20 = 7x + 14

Subtracting 7x from both sides of the equation:

5x-7x + 20 = 14\\-2x + 20 = 14

Subtracting 20 from both sides of the equation:

-2x = 14-20

Different signs are subtracted and the major sign is placed.

-2x = -6

Dividing between -2 on both sides of the equation:

x = \frac {-6} {- 2}\\x = 3

Thus, the solution of the equation isx = 3

Answer:

x = 3
