Answer:
y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
= ( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )
y = ≈ 61 ( to the nearest whole number )
1996-2000 = 4 years
$1400-$1200= $200 over 4 years
$200/4=$50 per year
2000-2008 = 8 years
50*8=400
1400+400=$1800
Answer: $1800
Answer:
m∠7 = 64°
Step-by-step explanation:
∠7 and ∠8 are supplementary meaning they add up to 180°.
m∠7 + m∠8 = 180°
m∠7 + 116° = 180°
m∠7 = 64°

Answer:
1094 ft
Step-by-step explanation:
The initial kinetic energy of the rocket will have been completely converted to potential energy when ...
1/2v^2 = gh
where v is the initial vertical velocity, g is the acceleration due to gravity, and h is the height attained. Solving for h gives ...
v^2/(2g) = h
(256 ft/s)²/(2(32 ft/s²)) = 1024 ft
The rocket will attain a height of 1024 feet above the building, or ...
1024 ft + 70 ft = 1094 ft . . . . height above the ground
Answer:
Part 1 is 420-10 and 210-5, part 2 is 200-10, and 300-15, etc.
Step-by-step explanation:
If this is what I think it is then you're just going to want to divide the first number by the second then once you get all four answers for each part you'll be able to see which ones match. Such as in part 1 you have:
340 and 20 which divides to get 17
420 and 10 which divides to get 42
450 and 30 which divides to get 15
210 and 4 which divides to get 42
Since the second and fourth row both have solutions of 42 they both have equivalent rates.
Hopefully this is what that assignment is asking!
