First, add 2.7 and 5 to get 7.7. Then, multiply 7.7 and 3 to get 23.1. Finally, subtract 2 from 23.1.

If you're distributing, then multiply 3 by 2.7 and 5. Then, add and subtract the sum by 2.

Hope this helped!

Answer:

A. (-1, 3)

Step-by-step explanation:

To solve, find which point in the options are in the double shaded region (the region that is shaded the darkest which is the region above the point where the lines cross).

A. (-1, 3) is the correct answer because it falls in the correct region.

B. (-4, 1) is not the correct answer because it does not fall ABOVE both lines like the question says.

C. (0, 1) is not the correct answer because it falls in the 2nd darkest region.

The inside ring of packing tape has a diameter of 80 mm. The tape surrounding the ring is 8 mm beyond the ring. What is the dist

Nutka1998 [239]

Answer:

301.44 mm

Step-by-step explanation:

Diameter of the inside ring of a packing tape = 80 mm

The tape surrounding the ring is 8 mm beyond the ring which means the diameter of the ring including the surrounding will be:

80 + 8 + 8 = 96 mm

and its radius will be = 96/2 = 48.

To find the distance around the outer edge of the tape, we need to calculate the circumference for the ring with the tape on it.

<em>Circumference = $2\pi r$ </em>

Circumference = 2 x 3.14 x 48 = 301.44 mm

Therefore, the distance around the outer edge of the tape is 301.44 mm.
