An airplane is flying 2 miles over the ocean directly toward a coastline. If the angle of depression to the coastline from the airplane is 15 degrees, how much farther does the airplane have to fly before it is directly above the coastline? Round to the nearest tenth.
The airplane has to fly approximately 7.47 miles farther before it is directly above the coastline (rounded to the nearest tenth).
Here,
Let's consider the situation described in the problem:
An airplane is flying 2 miles over the ocean, directly toward a coastline. The angle of depression from the airplane to the coastline is 15 degrees. We want to find out how much farther the airplane has to fly before it is directly above the coastline.
Let's represent the distance the airplane needs to fly before it is directly above the coastline as "x" miles.
Now, we have a right-angled triangle formed by the airplane, the coastline, and the point directly below the airplane on the coastline (the foot of the perpendicular).
The angle of depression is the angle between the horizontal line (the coastline) and the line of sight from the airplane to the foot of the perpendicular.
Since we know the angle of depression and the length of the opposite side (the height of the airplane above the coastline, which is 2 miles), we can use trigonometry (specifically, the tangent function) to find the length of the adjacent side, which is the distance the airplane needs to fly (x miles).
The tangent of an angle in a right-angled triangle is defined as the ratio of the length of the opposite side to the length of the adjacent side:
tan(angle) = opposite / adjacent
In our case, the angle is 15 degrees, the opposite side is 2 miles, and we want to find the adjacent side (x miles):
tan(15°) = 2 / x
Now, solve for x:
x = 2 / tan(15°)
Using a calculator:
x ≈ 2 / 0.26794919243 ≈ 7.47 miles
So, the airplane has to fly approximately 7.47 miles farther before it is directly above the coastline (rounded to the nearest tenth).

4. Komal sells five cups of hot chocolate for R30.
She writes the record of her sales in the equation 5x = 30.
If x is the cost of each cup of hot chocolate, at what price did
Komal sell each cup?
Answer:
R6 for each cup
Step-by-step explanation:
5x=30
Divide 5 from both sides
5x/5=30/5
x=6

Which point is located on ray PQ−→−? A line contains points M, N, O, P, Q, R, S with arrows instead of endpoints. point M point M point N point N point O point O point R
Answer:
R and S
Step-by-step explanation:
Given
See attachment for plot
Required
Point on ray PQ
A ray is a line with a starting point, and extends infinitely in the other direction.
So;
Ray PQ implies that.
P is the starting point, and it extends towards Q direction (however, it is endless).
Towards the direction of Q, we have points R and S.
This implies that R and S are on ray PQ.
Tatiana is playing a video game. She earns 25 points when she completes Level 1. Each time she completes a level, she earns three times as many points as the previous level.
How many points will Tatiana earn when she completes Level 7?
Answer:
18,225
Step-by-step explanation:
L1=25
L2=75
L3=225
the pattern is (25)* 3^(n-1)
L1=3^0*25 = 25
L2=3^1*25 = 3* 25 = 75
L3=3^2*25 = 9* 25 = 225
.
.
L7=3^6*25 = 729* 25 = 18,225

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.
Answer:
13 miles
Step-by-step explanation:
Distance from home to Field :
4² + 3² = d²
16 + 9 = d²
25 = d²
d = 5 miles
Field to Library :
8 lines so 8 miles
Total :
5 + 8 = 13 miles
He traveled 13 miles

Daniel is creating a rectangular garden in his back yard. The length of the garden is 14 feet. The perimeter of the garden must be at least 58 feet and no more than 66 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.
Answer:
15 ≤ w ≤ 19
Step-by-step explanation:
Given that :
Length of garden = 14 feets
Perimeter must be atleast 58 but no more than 66
The range of value for the width ;
Perimeter = 2 length + 2 width
Perimeter = 2(14) + 2w
If perimeter = 58
58 = 28 + 2w
58 - 28 = 2w
30 /2 = w
w = 15
If perimeter = 66
66 = 28 + 2w
66 - 28 = 2w
38 = 2w
w = 38 / 2
w = 19
Range of the width should be atleast 15 and not more Than 19
Hence,
15 ≤ w ≤ 19

A grocery store has a sale on apples. Shoppers can buy 3 bags of apples for $5. Each bag contains 6 apples. Which of the following statements is true?
Answer:
i dont know
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
3b = 5$
3b = 6a
3b = 3 bags
6a = 6 apples
A. It costs 3.60 for 1 bag of apples
3.60 + 3.60 = 60 + 60 = 120 + 3 = 123 + 3 = 126
Meaning it would cost 126 for 3 bags of apples making this a incorrect option
B. It costs 3.60 for 1 apple
B is wrong because its one apple and if we were to subtract the apple would probably only cost a few change not 3$ and 60 cents.
C. The cost of 9 bags of apples is 30$
9b = 21a, its either c or d but I'm pretty sure its D!
D. The cost of 108 apples is 30$
D is correct

One day, a café sells 3 more than twice the number of cappuccinos as they do lattes. They sold a total of 33 cappuccinos and lattes
together.
Which equation could be used to find the number of lattes, I sold at the café?
Answer:
10 lattes and 23 cappuccinos were sold.
Step-by-step explanation:
Given that one day, a café sells 3 more than twice the number of cappuccinos as they do lattes, and they sold a total of 33 cappuccinos and lattes together, to determine which equation could be used to find the number of lattes that were sold at the coffee the following calculation must be carried out:
Latte = X
Cappuccino = 2X + 3
X + 2X + 3 = 33
3X + 3 = 33
3X = 33 - 3
X = 30/3
X = 10
Latte = 10
Cappuccino = 2 x 10 + 3 = 23
Therefore, 10 lattes and 23 cappuccinos were sold.

The sum of a number and two times a smaller number is 62. Three times the bigger number exceeds the smaller number by 116. What are the numbers?
Answer:
SMALLER NUMBER = 14
BIGGER NUMNER = 34
Step-by-step explanation:
Two equations can be derived from the question
a + 2b = 62 equation 1
3a - b = 116 equation 2
a = bigger number
b = smaller number
multiply equation 1 by 3
3a + 6b = 186 equation 3
subtract equation 2 from 3
5b = 70
b = 14
substitute for b in equation 1
a + 28 = 62
a = 34
In ΔPQR, p = 7.6 inches, r = 3.5 inches and ∠R=160°. Find all possible values of ∠P, to the nearest 10th of a degree.
Answer:
There is no possible value for P
Step-by-step explanation:
In ΔPQR, p = 7.6 inches, r = 3.5 inches and ∠R=160°. Find all possible values of ∠P, to the nearest 10th of a degree
We solve using the law of sines
p/sin P = r/sin R
7.6/sin P = 3.5/sin 160
Cross Multiply
sin P × 3.5 = 7.6 × sin 160
sin P = 7.6 × sin 160/3.5
P = arc sin (7.6 × sin 160/3.5)
There is no possible value for P

As an estimation we are told £3 is €4.
Convert £33 to euros.
Answer:
44 euros
Step-by-step explanation:
if the ratio between an english pound and a euro is 3 to 4 respectivley, the ratios will hold true for any number. Since 33/3 = 11, we can stratigically multiply by 1,
3/4 = (3/4)(11/11)
so the ratios would be the same, multiplying, you would get 33/44, which means 33 pounds for 44 euros
