An object is moving at a speed of 920 yards every 3.5 hours Express the speed in miles per week

Kaylis [27]

Answer:

25.05 miles per week

Step-by-step explanation:

We know that,

1 mile = 1760 yards

⇒ 920 yards = 0.522 mile

1 week = 168 hour

We need to find ts speed in miles per week.

Speed = distance/time

$v=\dfrac{920\ \text{yards}}\\\\v=\dfrac{0.522\ \text{miles}}{\dfrac{3.5}{168}\ \text{week}}\\\\v=25.05\ \text{miles/week}$

So, the speed of the object is 25.05 miles per week.

Use the figure to the right to identify each pair of angles as alternate exterior,

madreJ [45]

7. ∠I and ∠M are corresponding angles.

8. ∠J and ∠P are alternate exterior angles.

9. ∠K and ∠M are alternate interior angles.

10. ∠L and ∠M are consecutive interior angles..

11. ∠I and ∠O are alternate exterior angles.

12. 7. ∠K and ∠O are corresponding angles.

<h3>What are Alternate Exterior Angles?</h3>

Angles that are formed outside the parallel lines that are intersected by a transversal and lie alternate to each other on along the transversal are alternate exterior angles.

<h3>What are Alternate Interior Angles?</h3>

Angles that are formed inside of the parallel lines that are intersected by a transversal and lie alternate to each other on along the transversal are alternate interior angles.

<h3>What are Consecutive Interior Angles?</h3>

Angles that are formed inside of the parallel lines that are intersected by a transversal and lie on the same side of the the transversal are consecutive interior angles.

<h3>What are Corresponding Angles?</h3>

Angles that are formed in relative corner position on each of the parallel lines that are intersected by a transversal and lie along the transversal in the same side are called corresponding angles.

Thus, from the image given, we have the following special angles:

7. ∠I and ∠M are corresponding angles.

8. ∠J and ∠P are alternate exterior angles.

9. ∠K and ∠M are alternate interior angles.

10. ∠L and ∠M are consecutive interior angles..

11. ∠I and ∠O are alternate exterior angles.

12. 7. ∠K and ∠O are corresponding angles.

A number cube is rolled 450 times. the number 3 comes up 67 times.a. what is the theoretical probability of rolling a 3? write y

OLga [1]

1- If the other 5 numbers on the cube aren't 3 the probability is 1/6

2-(Sorry I don't speak English well and I didn't understand the question) I think it's refereed to the first sentence, so it's 67/450=1/75

I need help ASAP!!!!

yawa3891 [41]

You can easily do this yourself. It takes more effort to create the question. Just multiply 22.854 by 5 then divide by 4 = 28.5675.
