Answer:

x² = 5×10

x = √50

x = √5²×2

x = 5√2

z² = 5² + (5√2)²

z = √25 + 50

z = √75

z = √5²×3

z = 5√3

y² = 10² + (5√2)²

y = √100 + 50

y = √150

y = √5²×6

y = 5√6

x = 5√2

y = 5√6

z = 5√3

Answer:

x = 5√2

y = 5√6

z = 5√3

ΔABC ~ ΔBDC ~ ΔADB

Step-by-step explanation:

ΔABC, ΔBDC, and ΔADB are all similar triangles to each other.

By definition of similar triangles, the corresponding sides have the same ratios.

CD from ΔBDC corresponds to BD from ΔADB, and BD from ΔBDC corresponds to AD from ΔADB. So:

CD / BD = BD / AD

10 / x = x / 5

x² = 50

x = 5√2

Since ΔBDC is right, we can use the Pythagorean Theorem to solve for y:

CD² + BD² = BC²

10² + (5√2)² = y²

y² = 100 + 50 = 150

y = 5√6

Again, since ΔΔABD is right, we can use the Pythagorean Theorem to solve for z:

AD² + BD² = AB²

5² + (5√2)² = z²

z² = 25 + 50 = 75

z = 5√3

8. What is the distance around the clock?
Elan Coil [88]

Answer:

The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

melisa1 [442]

Adam made an error of 400 meters

Explanation:

Since, submarine traveling 200 meters below the surface of the ocean

and when the depth increases by 45 meters then submarine new location is

200+45=245 meters below from the surface of ocean.

But Adam says that new location is at -155 meters.

So, error is,   245-(-155)=400 meters
