Use the Pythagorean theorem:

C = √[a^2 + b^2] 
C = √[(20^2 + 15^2] 
C =√[400 + 225] 
C = √(625) 
C = 25 inches 

Answer: 3.25 inches ✔️

SImplify: ((x+3)/9)/((x+12/)6)

dexar [7]

Flip the bottom part after the "/" so you get ((x+3)/9)*(6/(x+12)) Cancel and multiply to get 2(x+3)/3(x+12) this is as simplified as it is going to get.

Find the unit rate with the numbers 12 and one and one half

kati45 [8]

Answer:

The value of the unit rate is 8

Step-by-step explanation:

we know that

To calculate the unit rate simply divide the first number by the second number

$12:1\frac{1}{2}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}$

substitute in the expression above

$12:\frac{3}{2}=\frac{24}{3}=8$

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.
