Answer:
. A blimp is flying directly above a football field. The angle of depression. 555.OF+ to the base of one goal post is 40. The angle of depression to the base of the other goal post is 72". If the goal posts are 360 feet apart. 7. how high is the blimp flying? Round to the nearest tenth of a foot. : a Sih C 8 360 5in (68) 333.8 36 0F 7. The bearing from a lighthouse to Ship A is S71 E. The bearing from the lighthouse to Ship B is S 39° E. If Ship A is 15 kilometers from the lighthouse and Ship B is 96 kilometers from the lighthouse, find the distance between the ships. Find the areg of each triangle. Round answers to the nearest tenth. B. 84.0 8. 2. 11m ((uSin 64) 15.q ft 64 10.
The blimp flying is "237 m" high.
Angle of depressionAccording to the question,
In ΔABC,
∠XCA = ∠CAB = 72°
∠YCB = ∠CBA = 40°
Now,
→ ∠A + ∠B + ∠C = 180°
By putting the values,
72° + 40° + ∠C = 180°
112° + ∠C = 180°
∠C = 180° - 112°
= 68°
By applying Sin Rule,
→ [tex]\frac{AB}{Sin \ 68^{\circ}} = \frac{AC}{Sin \ 40^{\circ}}[/tex]
AC = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex]
We know that,
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° ...(Equation 1)
Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × h ...(Equation 2)
From "Equation 1 and 2",
→ [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° = [tex]\frac{1}{2}[/tex] × AB × h
h = AC × Sin 72°
By substituting value of "AC",
= [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex] × Sin 72°
= 237.36 or, 273 m
Thus the answer above is correct.

At the end of summer sale, an air conditioner that sold for $310 was discounted for 21%. What was the sale price?
Answer:
The sale price was $244.9.
Step-by-step explanation:
With the information provided, you can calculate the sale price by finding the 21% of the sale price and then, subtracting that amount from the sale price:
$310*21%=$65.1
$310-$65.1=$244.9
According to this, the answer is that the sale price was $244.9.

x = ±√((d -c)/a)
Step-by-step explanation:
The usual "solve for ..." approach works fine in this case.
ax^2 +c = d
ax^2 = d - c . . . . . subtract c
x^2 = (d -c)/a . . . . divide by a
x = ±√((d -c)/a) . . . take the square root

Comment on "solve for ..."
When solving an equation for a specific variable, it is worthwhile to consider the Order of Operations. Look at what has been done to the variable, then undo those operations in reverse order. Here, the variable has been squared, the product multiplied by 'a', that product added to c. So, the "undo" consists of subtracting 'c', dividing by 'a', and taking the square root.

Answer:
1. y ≥ 100
2. y ≤ 300
3. y ≥ 20000
4. 2y ≥ 80
5. 2y ≤ 90
Step-by-step explanation:
Let y be the variable.
1. The discount is not less than 100.
If the discount (i.e y) is not less than 100, it means it is either 100 or greater than 100.
This can be written as:
y ≥ 100
2. The cost of the book is at most 300.
This implies that the cost of the book (i.e y) is either 300 or lesser.
This can be written as:
y ≤ 300
3. His monthly income is at least 20000. This simply means that his monthly income (i.e y) is 20000 or greater than 20000.
This can be written as:
y ≥ 20000
4. Twice the number is at least 80.
Let the number be y.
Twice the number y can be written as:
2y
But twice the number is at least 80.
This means that twice the number is 80 or greater than 80. This can be written as:
2y ≥ 80
5. Twice the measure of the acute angle is not more than 90 degree.
Let the angle be y.
Twice the angle can be written as:
2y
But twice the measure of the angle is not more than 90 degree. This implies that twice the angle is 90 or lesser than 90. This can be written as:
2y ≤ 90

Answer:
m∠T = 79°
m∠V = 14°
Step-by-step explanation:
Given
m∠T = (2x + 85)°m∠V = (5x + 29)°As the sum of measures of the angles is 93°.
so
m∠T + m∠V = 93°
(2x + 85)° + (5x + 29)° = 93°
Remove parentheses
[tex]2x+85+5x+29=93[/tex]
[tex]7x+114=93[/tex]
Subtract 114 from both sides
[tex]7x+114-114=93-114[/tex]
Simplify
[tex]7x=-21[/tex]
Divide both sides by 7
[tex]\frac{7x}{7}=\frac{-21}{7}[/tex]
simplify
[tex]x=-3[/tex]
Determining m∠T
m∠T = (2x + 85)°
substitute x = -3
m∠T = (2(-3) + 85)°
= -6 + 85
= 79°
Thus, we conclude that m∠T = 79°
Determining m∠V
m∠V = (5x + 29)°
substitute x = -3
m∠T = (5(-3) + 29)°
= -15 + 29
= 14°
Thus, we conclude that m∠V = 14°
VERIFICATION:
m∠T + m∠V = 93°
substitute m∠T = 79° and m∠V = 14°
79° + 14° = 93°
93° = 93°
