Answer:
Part a.)
C = 3N
Note: Any variables could be used in this equation. It is important
that the students be able to define them.
Part b.)
3c + 750 = 1200 (or equivalent representation)
‐750 ‐750
3c = 450
c = 150
750 + 3c ≥ 1200
‐750 ‐750
3c ≥ 450
c ≥ 150
Parts c. and d.)
3(200) + 750 = T
600 + 750 = T
1350 = T

Answer:
Perimeter: 10.1 m
Area: 6.16 m^2
Step-by-step explanation:
For perimeter just add up all the sides except for 2.8 m since that is set aside for area.
For area multiply the length 2.2 by the height 2.8 m. The reason behind this is that using a slanted height makes know sense sine when you measure things they should be perfectly as possible vertical
The answer is B
12 divided by 3/2 is the same as 12 x 3/2
Do this to 8 to get the answer B
You need to set a variable to represent the width, let's say "w'.
width = w
length (l) = 20 + w
Area = length * width
A = (20 + w) * w
See how I substituted the length in terms of w, above? We also know the area, so plug that in:
A = (20 + w) * w
1500 = (20 + w) *w
Solve for w. If it's easier, rewrite as:
1500 = w(20 + w)
Distribute the right side, and solve for w (width).
Then plug back into the equation for length --> length = 20 + w to find the other dimension
Applying the sine ratio and the law of sines, the value of h in the diagram is: B. 3.2 yards.
<h3>What is the Sine Ratio?</h3>
Sine ratio for solving a right triangle is: sin ∅ = opp/hyp.
Let's find AT in triangle BAT using the given Law of Sines:
m∠BTA = 180 - (180 - 57) - 46 = 11°
AB = 1 yd
m∠ABT = 46°
Using the law of sines, we have:
sin(m∠ABT)/AT = sin(m∠BTA)/AB
Plug in the values
sin(46)/AT = sin(11)/1
AT = sin(46) × 1 / sin(11)
AT = 3.8 yards
Find h using the sine ratio:
∅ = 57°
Opposite = h
Hypotenuse = AT = 3.8 yards
Substitute
sin 57 = h/3.8
h = sin 57 × 3.8
h ≈ 3.2 yards.
