Answer: Two and one tenth.
5
The reason is because |-5| is equal to 5. The absolute value bars make the number positive.
Hi DerpyIntelligence!
The product is addition so we do -3 1/4+-1 1/2. We solve it like this. We separate each part like this (-3)+(-1/4)+(-1)+(-1/2) then we solve the whole parts (-3)+(-1)=(-4). Next we find out the LCD of (-1/4) and (-1/2) which is 4 so we change (-1/2) to (-2/4) than we add (-1/4) which is (-3/4). Finally we add the wholes to the fractions (-4)+(-3/4)=(-4 3/4)
Hope this helps!

Answer:
89.0°
Step-by-step explanation:
The measure of arc CD is the same degree measure as the central angle.
To find the central angle use the right triangle.
The segment from the centre to the chord is a perpendicular bisector, thus
the third side of the triangle = 12.7 ÷ 2 = 6.35
Calculate one half of the central angle using the sine ratio and multiply by 2 for the whole central angle
sin( one- half ) =
= 
, hence
central angle = 2 × 
( ) ≈ 89.0°
Hence measure of CD ≈ 89.0°
