Anni [7]3 years ago
8 0

Answer:

x = 3

Step-by-step explanation:

Given :

AE = 3, EB = 4, CE = x, and ED = x +1,

Equating chord AB and CD

AE*EB = CE*ED

3*4 = x*(x+1)

12 = x² + x

x² + x - 12 = 0

x² +4x - 3x - 12 = 0

x(x + 4) - 3(x + 4)

(x + 4) = 0 or (x - 3) = 0

x = - 4 or x = 3

Distance can't be negative :

x = 3

Ken drives his car 800 miles in 3 days. At this rate, how far will he drive his car in 5 days?
LenaWriter [7]

Answer:

1333.35 miles

Step-by-step explanation:

Given: 800 miles in 3 days

To find: How far will he drive his car in 5 days?

Solution: If Ken drives his car 800 miles in 3 days, to find how many miles it will take him at the same rate, we need to divide 800 miles by 3 days

800 ÷ 3 = 266.666666667

Simplified

266.67

Now that has been figured out, we need to multiply the result by the 5 days it will take Ken.

266.67 × 5 = 1333.35

Hence, At the rate of 800 miles in 3 days, Ken will drive 1333.35 miles in 5 days.

Answer:

Volume of cylinder = 192π inch³

Step-by-step explanation:

Given:

Diameter of base = 8 inch

Length of cylinder = 12 inch

Find:

Volume of cylinder

Computation:

Radius of cylinder = Diameter of base / 2

Radius of cylinder = 8 / 2

Radius of cylinder = 4 inch

Volume of cylinder = πr²h

Volume of cylinder = π(4)²(12)

Volume of cylinder = π(16)(12)

Volume of cylinder = 192π inch³
