Answer:
Step-by-step explanation:
Remark
Triangle BAC is isosceles. It has 2 sides that are both radii of the circle. I assume that C is the center of the circle.
Givens
AC = BC Both of these are radii.
<BCD = 20o Given
<A and <B are equal Both are opposite a radii of the circle
C is the circle's center Assumed otherwise we can't do it.
Solution
<BCD is an exterior angle of Triangle ACB It's on the same straight line as D and A
The sum of 2 remote interior angles = the sum of the exterior angle.
BAC = ABC Stated above
BAC + ABC = 20 Stated right above.
2BAD = 20
BAD = 20/2
BAD = 10
Distributive property is when you multiply the number outside the parenthesis by the one inside. 9(475)
Answer:
Yes
Step-by-step explanation:
Radius = 2÷2 = 1
Volume of sphere
= (4/3)×3.14×1³ = 314/75 in³
(4.18666767 in³)
Volume of cone
= ⅓×3.14×1²×5 = 157/30 in³
(5.2333333 in³)
Since the volume of cone is greater than the scoop, it will be able to hold melted icecream
Answer:
AB = 5
Step-by-step explanation:
Calculate the distance using the distance formula
d =
with (x₁, y₁ ) = A(6, 3) and (x₂, y₂ ) = B(- 1, 4)
AB =
=
=
=
= 5 ← exact value
≈ 7.07 ( to 2 dec. places )
Answer:
29.8 × 10⁸
Step-by-step explanation:
The average life span for human is 79 years
And healthy heart beats 72 times a minute
Now,
Total number of minutes in 79 years = 79 × 365 × 24 × 60
therefore,
The total number of times heart beats in the life span
= 72 × 79 × 365 × 24 × 60
= 2989612800 times
now, to convert it into an answer with 10⁸
divide the result with 10⁸
Hence,
The total number of times heart beats in the life span = 29.8 × 10⁸ times
