Part 1 out of 2 Select the real-world problem best represented by the equation 15x = 570. A An elephant walks with a speed of 15

nika2105 [10]

Answer:

Option A.

Step-by-step explanation:

We will check each option given in the question.

Option A. If an elephant walks with the speed = 15 steps a minute

If it takes x hours to cover 570 steps then the expression should be

15x = 570

Therefore, Option A. will be the answer.

Option B. A giraffe eats leaves = 570 per hour

If it eats for 15 hours then number of leaves eaten by giraffe = 570×15

So the expression is not formed.

Therefore, Option B is not the answer.

Option C. Dandelions eaten by the donkey = 15

and dandelions eaten by cow = 570

So total dandelions eaten by cow and donkey together = 15 + 570

Again the expression is different so Option C is incorrect

Option D. A Canary flew for 15 hours towards north, then turned east and flew for 38 hours.

Here speed of the canary is not mentioned so it's not possible to form any expression for the distance covered by the canary.

Therefore, Option D is also incorrect.

Option A. is the answer.

Daniel created an intersection with his race track. One of the angles at the intersection is 55°. What are the three other angle

melomori [17]

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.
