A polar bear travels across the snow at a rate of 25 miles per hour. Which representation shows the distance a polar bear can travel at this rate?

A. y = x + 25
B. y = 25x
C. y = x - 25
D. y = 1/25x

Answers

Answer: B

Step-by-step explanation:

Y (distance) is 25 multiplied by x

x is how many hours

so if we make x hours,

25x = y

B is the answer because x represents the hours. We know that 25 is how many miles the bear can travel per hour. Therefore, y = 25x

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:

Answers

Answer:

Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

Circle: The area of a circle is pi times the radius squared (A = π r²).

Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.
