Answer:
m<ALO=35°
Step-by-step explanation:
we know that
The right triangle AOL is congruent with the right triangle BOL
because
OA=OB=radius of the circle
OL is a common side
LA=LB ---> by applying the Pythagoras theorem
therefore
m<AOL=m<AOB/2
m<AOL=110°/2
m<AOL=55°
Remember that
m<AOL+m<ALO=90° ------> by complementary angles
m<ALO=90°-55°=35°
Just answer each one to the best of your ability... study the graph and say what’s happening, like so many gallons per hour or something like that
First find least common denominator to subtract.
9=(3)×3
15=(3)×5
3×3×5=45 is lcd
4/9=20/45
7/15=21/45
(20/45-21/45)=(20-21)/45=-1/45
-1/45÷13/10
multiply by reciprocal instead of dividing
-1/45×10/13=(1×10)/(45×13)
-10/585
Answer:
The radius is 1.75 cm, 1 3/4 cm, or 7/4 cm (all the same, just in different forms)
The circumference in terms of π is 7/2(π) cm, 3.5(π), or 3 1/2(π) cm (all the same, just in different forms)
The approximate circumference of the circle is 10.99 or 11 cm. (don't know if it's supposed to be rounded)
Step-by-step explanation:
Radius = 1/2 of the diameter, so 1/2 of 7/2 is 1.75, 1 3/4, or 7/4 cm.
Circumference in terms of pi means to not approximate pi. Circumference of circle is πd, so the exact circumference would be 7/2 pi cm, 3.5 pi cm, or 3 1/2 pi cm.
3.5 x 3.14 = 10.99. 10.99 cm ≈ 11 cm.
54,984 rounded to the nearest ten thousand would be 50,000 since you are rounding to the nearest 10,000 you will round 4,000 to 50,000
