Answer:

5√2 units ≈ 7.07 units

Step-by-step explanation:

The ratio of leg to hypotenuse in an isosceles right triangle is ...

leg/hypotenuse = 1/√2

Multiplying by the length of the hypotenuse, we have ...

leg = hypotenuse/√2 = 10/√2

leg = 5√2 . . . . rationalize the denominator

The length of one leg is 5√2 units, about 7.07107 units.

ANSWER

$x=10$

and

$y=20$

EXPLANATION

Since corresponding angles are equal,

$4x+y=60---(1)$

Alternate angles are also equal, therefore,

$8x+y=100---(2)$

Equation (2) minus equation (1) gives,

$\Rightarrow 4x=40$

$\Rightarrow x=10$

We put $x=10$ in to equation (1)

$4(10)+y=60$

$y=60-40$

$y=20$

Sergeeva-Olga [200]

Answer:

The correct answer is 54 miles per hour

Step-by-step explanation:

To solve this problem we have to use the formula of

Speed=Distance/time

Both, car an truck made the same distance, so

Distance car=Speed car*time car

Distance truck =Speed truck*time truck

Distance car=Distance truck

So Speed car*time car =Speed truck*time truck

Speed car =Speed truck* time truck /time car

Time truck = time car +2 ( truck leaves 2 hours before)

Time car =10

Speed car =45 miles per hour* 12 /10

Speed car = 54 miles per hour
