Emily, Frances, and Bill each carried a 10-pound bag of soil into the backyard. After putting the soil in the first flower bed, Emily's bag was ⅝ full, Frances's bag was ⅖ full, and Bill's bag was ⅖ full. How many pounds of soil did they put in the first flower bed altogether?

Step-by-step explanation:

emily: 10(5/8) = 6 1/4 or 6.25 pounds left

10- 6.25 = 3.75 used

Frances : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

Bills : 10(2/5) = 4 pounds left

10-4 = 6 pounds used

add them together

15.75 or 15 3/4 pounds of soil in the first flower bed

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
