It's B.) The student’s answer is not reasonable. Estimation: 170 + 90 = 260

The answer is B because if you round to the nearest 10, B would be the answer. C is not correct because 93 rounded to the nearest 5 (like 175) is not 100. A is not correct because the estimation is not reasonable. D is also not correct because you would need to add the numbers, not subtract.

How long will it take you to drive 225 miles of the speed of 25 mph
podryga [215]

HEy!!

So you drive 25 miles / hour.

Which is equal to 225 miles / number for hours driven

then 25 miles/ 1 hour  = 225 miles / number  of hours.

distance / speed = time

225 / 25 = time

time = 9

9 miles/hr

antoniya [11.8K]

Answer:

87.5 square inches

Step-by-step explanation:

The belt knuckle as shown in the diagram above consist of a 4 rectangles (2 are the of the same dimension, the other two are of the same direction differently) and a rectangle.

Area of the belt knuckle = area of the 4 triangles + area of the rectangle

✔️Area of the 2 rectangles with the following dimensions:

base (b) = 9 inches

height (h) = 2.5 inches

Area of the two triangles = 2(½*b*h)

= 2(½*9*2.5)

= 22.5 inches²

✔️Area of the 2 rectangles with the following dimensions:

base (b) = 4 inches

height (h) = 5 inches

Area of the two triangles = 2(½*b*h)

= 2(½*4*5)

= 20 inches²

✔️Area of the rectangle = l*w

l = 9 inches

w = 5 inches

Area = 9*5 = 45 inches²

✔️Area of the belt knuckle = 22.5 + 20 + 45 = 87.5 square inches
