A tower that is 126 feet tall casts a shadow 148 feet long. Find the angle of elevation of the sun to the nearest degree.
The angle of elevation is ____ degrees.
Answer:
[tex] \boxed{\theta = 40 \degree}[/tex]
Step-by-step explanation:
[tex] \tan( \theta ) = \frac{opp}{adj} = \frac{126}{148} \\ \theta = { \tan}^{ - 1} (0.8513) \\ \theta = 40.4[/tex]

Group A is on the north side of the fire and is 800 ft away from group B and 900 feet away from group C. Group A knows that the angle between its two adjacent sides is 89.6. “
The emergency responders want to properly inform the nearby towns of the danger proximity. They will need all three angles. To do this they need some additional information. The emergency responders need to know the angle of Group B and Group C. They also need to know the distance between Groups B and C.
Answer:
1. Length BC is 1200 ft
2. Angle B is 48.6°
3. Angle C is 41.8°
Step-by-step explanation:
1. Determination of the length BC
Side opposite C = c = 800 ft
Side opposite B = b = 900 ft
Angle A = 89.6°
Side opposite BC = a =?
Using cosine rule, we can obtain length BC as follow:
a² = b² + c² – 2bc CosA
a² = 900² + 800² – 2 × 900 × 800 × Cos89.6
a² = 810000 + 640000 – 1440000 × 0.007
a² = 1450000 – 10080
a² = 1439920
Take the square root of both side
a = √1439920
a ≈ 1200 ft
Thus, length BC is 1200 ft
2. Determination of angle B
Side opposite B = b = 900 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle B =?
Angle B can be obtained by using sine rule as follow:
a / Sine A = b / Sine B
1200 / Sine 89.6° = 900 / Sine B
Cross multiply
1200 × Sine B = 900 × Sine 89.6°
1200 × Sine B = 900
Divide both side by 1200
Sine B = 900/1200
Sine B = 0.75
Take the inverse of Sine
B = Sine¯¹ 0.75
B = 48.6°
Thus, angle B is 48.6°
3. Determination of angle C
Side opposite C = c = 800 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle C =?
Angle C can be obtained by using sine rule as follow:
a / Sine A = c / Sine C
1200 / Sine 89.6° = 800 / Sine B
Cross multiply
1200 × Sine C = 800 × Sine 89.6°
1200 × Sine C = 800
Divide both side by 1200
Sine C = 800/1200
Sine C = 0.6667
Take the inverse of Sine
C = Sine¯¹ 0.6667
C = 48.6°
Thus, angle C is 41.8°

In speech class, Carolyn needs at least a B + to keep her financial aid. To earn a B+, the average of her four speeches must be at least an 85. On the first 3 she scored 85, 77, and 81. Determine the minimum score speech to get a B+.
Answer:
The minimum score speech to get a B+ is 89.Step-by-step explanation:
Average of the first 3 = 85 + 77 + 81 / 3
= 243 / 3
= 81
The fourth score ( to get 85 ) = 81 + 89
= 170 / 2
= 85
Answer:
97
Step-by-step explanation:
Relative to the average she wants, Carolyn's scores are ...
85-85 = 0
77-85 = -8
81-85 = -4
Carolyn's score total is -8-4 = -12 points from the average she wants, so she must get 85+12 = 97 on her speech to achieve a B+ average.
_____
Check
With a 97, Carolyn's average would be ...
(85 +77 +81 +97)/4 = 340/4 = 85

In the Special Right Triangle below, solve for the value of y. Y = _____ (keep your answer in simplest radical form)
Options
5
5√2
10
10√2
Answer:
Value of Y = 5√2 units
Step-by-step explanation:
Given:
Perpendicular = X
Base = Y
Hypotenuse = 10
Find:
Value of Y
Computation:
Cos θ = Base / Hypotenuse
Cos 45 = Y / 10
1/√2 = Y / 10
Value of Y = 5√2 units

Select the correct answer.
Jamal is comparing his transportation options for an upcoming trip. He's considering a rental car and a taxi service. Based on his planned routes
during his trip, he expects a taxi service would cost about $128. Jamal could also get a rental car for a dally rate and unlimited miles. If Jamal's
trip will last 4 days and he expects to pay about $24 for gas, which graph shows the range of car rental rates that would be cheaper than the taxi
service?
The range of rental car rates that would be cheaper for Jamal than the taxi service and the graph of inequality x<26 is shown.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
Let's suppose the rental car rate is:
$x per day
Number of days of Jamal's trip = 4 day
He expects to pay $24 for gas (for car rent)
He expects a taxi service would cost about $128
Inequality can be modelled:
128 > 24 + 4x
4x < 104
x < 26
Thus, the range of rental car rates that would be cheaper for Jamal than the taxi service and the graph of inequality x<26 is shown.

Step-by-step explanation:
Lucy went to the store with $50. She bought a pair of jeans for $14.99, three shirts for $4 each, and a bag of Cheetos for $2.25. While at the store, she found another $10 in the bottom of her purse. How much money did Lucy have when she left the store?
Answer:
$30.76
Step-by-step explanation:
Subtract the costs of her purchases from her total of 50:
50 - (14.99 + 3(4) + 2.25)
50 - (14.99 + 12 + 2.25)
50 - 29.24
= 20.76
Now, add the $10 that she found to this:
20.76 + 10
= 30.76
So, when she left the store, Lucy had $30.76

Step-by-step explanation:
Answer:
84/12
Step-by-step explanation:
since 7 is a whole, you need to make it a improper fraction so its easier to subtract. We need to do this by making sure the denominator stays the same which is 12.Then do 7x12. you get 84, so 84/12. Then its easier to solve.
Find the sample variance and standard deviation of:
21, 12, 3, 9, 11
s2=?
Answer:
42. 2
6.496
Step-by-step explanation:
Given the data :
21, 12, 3, 9, 11
Variance :
S² = Σ(x - m)² ÷ (n - 1)
n = sample size = 5
m = sample mean = Σx / n
m = (21 + 12 + 3 + 9 + 11) / 5
m = 11. 2
(21-11.2)² + (12 -11.2)² + (3 - 11.2)² + (9-11.2)²
+ (11-11.2)² / (5 - 1)
S² = 42.2
Standard deviation, s = sqrt(42.2) = 6.496
