Hand: 27 bones
Body: 206 bones
Percent of bones in hand of all human body is expressible by 27 divided by (/) 206 times (*) 100.
27/206=0.13*100=13%
Roughly 13% of bones in the body is in one human hand.
26% in 2 hands. Expressible by 13%*2.
Answer:
x=2
Step-by-step explanation:
to find x- intercept substitute y=0
move variable to the left hand side and change its sign -5x=-10
then divide both sides of the equation by -5
and the final answer is x=2
hope this helps!
Answer:
t = [0.493,4.2]
Step-by-step explanation:
The height of the rocket straight up into the air is given by :

We need to find the interval the rocket be at least 43 feet above the ground.

So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].
Answer:
BD = <u>1</u> unit
AD = <u>1</u> unit
AB = <u>1.6</u> units
AC = <u>1.6</u> units
Step-by-step explanation:
In the picture attached, the triangle ABC is shown.
Given that triangle ABC is isosceles, then ∠B = ∠C
∠A + ∠B + ∠C = 180°
36° + 2∠B = 180°
∠B = (180° - 36°)/2
∠B = ∠C = 72°
From Law of Sines:
sin(∠A)/BC = sin(∠B)/AC = sin(∠C)/AB
(Remember that BC is 1 unit long)
AB = AC = sin(72°)/sin(36°) = 1.6
In triangle ABD, ∠B = 72°/2 = 36°, then:
∠A + ∠B + ∠D = 180°
36° + 36° + ∠D = 180°
∠D = 180° - 36° - 36° = 108°
From Law of Sines:
sin(∠A)/BD = sin(∠B)/AD = sin(∠D)/AB
(now ∠A = ∠B)
BD = AD = sin(∠A)*AB/sin(∠D)
BD = AD = sin(36°)*1.6/sin(108°) = 1
