Opal wanted to make some necklaces and sell them at a craft store. She made 37 necklaces and each necklace had somewhere between

alexandr402 [8]

<h3>The total number of beads used in making 37 necklaces is between 2,664 beads and 2,849 beads.</h3>

Step-by-step explanation:

Here, as given: The number of necklace made by Opal = 37

The least number of bead used in each necklace = 72

So, if each necklace is made using the least number of beads then,

The total number of beads used in 37 necklace = 37 x ( beads in 1 necklace)

= 37 x 72 = 2,664 beads

So, the least number of total beads used in 37 necklaces = 2,664 beads

The highest number of bead used in each necklace = 77

So, if each necklace is made using the highest number of beads then,

The total number of beads used in 37 necklace = 37 x ( beads in 1 necklace)

= 37 x 77 = 2,849 beads

So, if highest number of total beads used in 37 necklaces = 2,849 beads

Hence, the total number of beads used in making 37 necklaces is between 2,664 beads and 2,849 beads.

What is the product of 7/16 and -6/13 I will make you the brainlest

mr_godi [17]

Answer:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$

Step-by-step explanation:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$ . First multiply 7*-6=-42.

Then do 16*13=208.

Simplify by dividing both by 2.

You get $\frac{-42}{208}=\frac{-21}{104}$ .

Your final simplified answer is $\frac{-21}{104}$

I hope this helps!
