Answer:

24 bookmarks.

n = 12 \times (1 \div \frac{1}{2})

Step-by-step explanation:

Ed is making 1/2 foot long bookmarks out of leather strips.

Now, if he has 12 leather strips that each measure 1 foot long, then each of the 1-foot leather strip can be made into 1 \div \frac{1}{2} = 2 half foot long bookmarks.

Hence, from all the 12 leather strips he can make (12 × 2) = 24 bookmarks.

So, the equation that represents the number of bookmarks that can be made will be, n = 12 \times (1 \div \frac{1}{2}) (Answer).

HELP ME PLZZZZ!!!!!<br><br><br> It’s just 21 and 22
galina1969 [7]

Answer:

21) 12 cm

22) 5.9 cm

Step-by-step explanation:

21) The base is 10, and if the other two sides are congruent and the perimeter is 36, we can figure out with simple algebra that the sides are 13 cm long.

Half of 10 is 5, so we can use the pythagorean theorem.

5^2+x^2=13^2

Rearranging the variables we have 169-25=x^2

144=x^2

x can be plus or minus 12, but since negative length is impossible we find that x is positive 12 cm.

22) We want to use sine, because we have opposite and hypotenuse. A simple and easy way to memorize this is the SohCahToa method. If we have opposite (O) and hypotenuse (H) we have OH. Soh has the letters O and H, and the S means we should use sine.

sine 36=a/10

Plug this into a calculator or desmos scientific calculator to get a=5.9
