Answer:

DOC = 70

BOC = 110

AOD = 110

Step-by-step explanation:

AOB is supplementary to BOC and AOD, which means together they equal 180. 180-70=110, so BOC and AOD are both 110.

AOB and DOC are vertical angles to each other, so are AOD and BOC. Vertical angles are always equal to each other. So since AOB is 70, so is DOC.

Hope this makes sense:)

Grace started her own landscaping business. She charges $6 an hour for mowing lawns and $11 per house pulling weeds. In Septembe

marshall27 [118]

Answer:

The total money made by Grace is $477.

Step-by-step explanation:

Given:

Charge per hour for mowing lawn = $6

Charge per hour for pulling weeds = $11

Number of hours for which lawns are mowed = 63 hours

Number of hours for which weeds are pulled = 9 hours

Now, total money made by Grace in September can be calculated by adding the total money gained in mowing lawns and pulling weeds.

Total money gained in mowing lawns is given as:

$C_m=\textrm{Number of hours of mowing}\times\textrm{Charge per hour}\\\\C_m=63\times 6=\$378$

Total money gained in pulling weeds is given as:

$C_w=\textrm{Number of hours of pulling weeds}\times\textrm{Charge per hour}\\\\C_w=9\times 11=\$99$

Now, total money made = $C_m+C_w=378+99=\$477$

Therefore, the total money made by Grace is $477.
