Answer:

  • 2 mph

Step-by-step explanation:

Let the speed of current be x

<u>Speed of the boat in same direction as current is</u>

  • 10 + x

<u>Speed against the current is</u>

  • 10 - x

<u>Based on the given we get the equation for time</u>

  • 6/(10 + x) = 4/(10 - x)

<u>Solving for x</u>

  • 6(10 - x) = 4(10 + x)
  • 60 - 6x = 40 + 4x
  • 6x + 4x = 60 - 40
  • 10x = 20
  • x = 2

The answer is 2 mph

A six-faced die is rolled .
STatiana [176]

Answer:

[A] 2/6

[B] 1/2

Step-by-step explanation:

Given:

A six-faced die is rolled .

To Find:

Find the probability of it landing on a value more than 4

Find the probability of it landing on an even number

Part A:

Knowing that a six-faced die has six number on it (1,2,3,4,5,6)

Thus, the probability of it landing on an value more than 4 is 2/6.

Because 5 and 6 is more than 4

Part B:

1,3,5 = Odd

2,4,6 = Even

Thus, the probability of it landing on an even number is 3/6 Simplify 1/2 . Which also is 50%.

Need some math help thanks in advance!
vredina [299]

Answer:

x = 10

y = 6

Step-by-step explanation:

<u>Vertical Angle Theorem</u>:  When two straight lines intersect, the opposite vertical angles are always equal to each other.

⇒ m∠1 = m∠3   and   m∠2 = m∠4

⇒ m∠1 = m∠3

⇒ 10x = 100

⇒ x = 10

<u>Linear pair:</u>  Two adjacent angles which sum to 180°.

⇒ m∠1 + m∠2 = 180°

⇒ m∠3 + m∠4 = 180°

⇒ 100 + 10y + 20 = 180

⇒ 120 + 10y = 180

⇒ 10y = 60

⇒ y = 6
