There is 360* in a circle, so you would divide 360 by 20 to get 18.

Solution:

As we given that $1 inch=2.54 cm$

then using this conversion factor we can write $28.4 inch=28.4* (1 inch)$

and further it can be written as

$28.4* (1 inch)*(2.54 cm/1 inch)=28.4*2.54 cm= 72.136 cm$

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.

Answer:

d = 5

Step-by-step explanation:

We want to know what d would be when x = -1, so we can start off by plugging in -1 for x to get the following equation: $\sqrt{8 - (-1)} = 2(-1)+d$ . On the left hand side, 2 negatives become a positive sign, so the -(-1) becomes a +1, and 8+1 would equal 9. On the right hand side, we just multiply 2 and -1 to get -2. So, the equation now looks like this: $\sqrt{9} = d-2$ . We know that $\sqrt{9}$ = 3, so we would get 3 = d-2. THen we would add 2 to both sides to get d = 5. Hope this helps!
