An athlete runs 8 miles in 50 minutes on a treadmill. At this rate how long will it take the athlete to run 9 miles? Your answer

zvonat [6]

56.25 minutes

Explanation: to find how long it takes to run one mile, divide 50 minutes by 8 miles.
50/8 = 6.25
Then you can multiply 6.25 by 9 to find the answer.
9 x 6.25 = 56.25 minutes

Simplify. √20 * √3 * √18 5√10 6√10 5√30 6√30

natulia [17]

Answer:

D: 6√30

Step-by-step explanation:

Simplify the following:

sqrt(20) sqrt(3) sqrt(18)

sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):

sqrt(20) sqrt(3)×3 sqrt(2)

sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):

2 sqrt(5) sqrt(3)×3 sqrt(2)

2×3 = 6:

6 sqrt(5) sqrt(3) sqrt(2)

sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):

6 sqrt(5×3×2)

5×3 = 15:

6 sqrt(15×2)

15×2 = 30:

Answer: 6 sqrt(30)

Annie spent 2.5 hours doing homework. She spent 1/3 of the time on her history project. She spent 3/5 of the remaining time solv

Scilla [17]

Step-by-step explanation:

2.5 hours = 150 min

1/3 of 150 is 50 min, which means she spent 50 min on her history project = 100 min leftover

3/5 of 100 min is 60 min (1 hour) = 40 min leftover

She spent 40 min writing her essay

The coordinates of the vertex that A maps to after Daniel's reflections are (3, 4) and the coordinates of the vertex that A maps to after Zachary's reflections are (3, 2)

<h3>How to determine the coordinates of the vertex that A maps to after the two reflections?</h3>

From the given figure, the coordinate of the vertex A is represented as:

A = (-5, 2)

The coordinates of the vertex that A maps to after Daniel's reflections

The rule of reflection across the line x = -1 is

(x, y) ⇒ (-x - 2, y)

So, we have:

A' = (5 - 2, 2)

Evaluate the difference

A' = (3, 2)

The rule of reflection across the line y = 2 is

(x, y) ⇒ (x, -y + 4)

So, we have:

A'' = (3, -2 + 4)

Evaluate the difference

A'' = (3, 4)

Hence, the coordinates of the vertex that A maps to after Daniel's reflections are (3, 4)

The coordinates of the vertex that A maps to after Zachary's reflections

The rule of reflection across the line y = 2 is

(x, y) ⇒ (x, -y + 4)

So, we have:

A' = (-5, -2 + 4)

Evaluate the difference

A' = (-5, 2)

The rule of reflection across the line x = -1 is

(x, y) ⇒ (-x - 2, y)

So, we have:

A'' = (5 - 2, 2)

Evaluate the difference

A'' = (3, 2)

Hence, the coordinates of the vertex that A maps to after Zachary's reflections are (3, 2)
