Answer:
well if the bottom two are 30 then that leaves you with 70
Step-by-step explanation:
Answer:
True False True
Step-by-step explanation:
1. A circle has 360 degrees in its interior. 360 - 130 (this is given) degrees = 230 degrees. This means it's TRUE
2. The area of the shaded sector is the degrees in the central angle that contains the sector, multiplied by the area of the circle. This means that the area is pi*r^2*angle. The radius is 10, and the angle is 230 degrees, so the answer is 100*230/360 pi = 23000/360 pi, which simplifies to 575/9 pi. This is FALSE.
3. The area of the shaded sector is area of the circle - area of the shaded sector. The area of the circle is pi r^2, which is 100 pi. 100 pi - 575/9 pi = 325pi/9, so this is TRUE
Answer:
79
Step-by-step explanation:
angles add up to 360
360-134-58=158
there are two angles so 158 divide by 2 is 79
Answer:
91/4 (it already is an improper fraction)
Step-by-step explanation:
91/4 isn't proper as u can tell. The proper form would be 22
. So yea...
Hope this helped and have a great day!
Answer:
$1.54 per pound
Step-by-step explanation:
The
pound bag of yarn costs $5.25.
To find the unit rate, we divide 5.25 by
To the nearest tenth,each pound costs $1.54 to the nearest cent.
This is what we call the unit rate. The rate per pound.
