Please help and show work if you can I only need 10, 11 and 12

postnew [5]

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

3x + 1 = 6x - 4

6x - 3x = 1 + 4

3x = 5

x = $\frac{5}{3}$

11). If ABCD is a parallelogram,

AB = CD

5x - 8 = 2x + 7

5x - 2x = 7 + 8

3x = 15

x = 5

12). If ABCD is a parallelogram,

AB = CD

AB║CD and BD is a transversal intersecting these parallel lines.

∠ABD ≅ ∠BDC [Alternate interior angles]

4x - 1 = x + 38

4x - x = 38 + 1

3x = 39

x = 13

A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters. Which expression gi

goldenfox [79]

Start with the volume equation for a sphere:

V=4/3pi•r^3

The dimensions of the cylinder allow for a sphere with a diameter of 20 centimeters, so the radius of this sphere will be 10 centimeters. Substituting this into the equation:

V=4/3pi•(10)^3

or the uppermost right answer (B).

-4.2x 31.5=165.1 solve

Ymorist [56]

Answer:

x = −1.24

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−132.3x=165.1

Step 2: Divide both sides by -132.3.

$\frac{-132.3x}{-132.3} = \frac{165.1}{-132.3} \\$

x= -1.247921
