Fred needs 12 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 18 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of same dimension can he wrap using the spool of ribbon

5

Step-by-step explanation:

The computation of the gits is shown below;

Given that

The ribbon which is used to wrap the gift = 1.2m

The ribbon that he spoiled = 18feet

based on the above information

As we know that 3feet = 1m

1foot = 1 ÷ 3 m

Now

18feet = 1 ×18 ÷ 3

18 feet = 6m

Now,

gift can be packed = 6 ÷ 1.2

= 60 ÷ 12

= 5

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
