A jet fighter is going to land on a battleship. The angle of depression it lands at is 20 degrees. If it is 10,000 ft in the air, how far across the sea will it travel?
Answer:
10641.777 feets
Step-by-step explanation:
To obtain the distance to be traveled across the sea, we use trigonometry :
Cosθ = adjacent / hypotenus
Adjacent = 10000
Hypotenus = d
θ = 20°
Cos 20° = 10000 / d
0.9396926 = 10000 / d
d = 10000 / 0.9396926
d = 10641.777
The jet fighter will travel 10641.77 ft far across the sea.
It is given that angle of depression it land at is 20°.
It is required to find how far the sea will travel.
What is the trigonometric ratio?The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
We have an angle of depression = 20°
The height from the sea level = 10,000 ft
From the figure:
[tex]\rm cos20 = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\rm 0.939 = \frac{10000}{d}[/tex]
d = 10641.77 ft
Thus, the jet fighter will travel 10641.77 ft far across the sea.

Tara is planting a garden. There are 25 rows with 12 zucchini plants in each row. There are also 32 rows with 14 tomato plants in each row. How many total plants are there in the garden?
A.300
B.448
C.748
D.148
Answer:
C. 748
Step-by-step explanation:
25 rows x 12 zucchini plants = 300 zucchini plants total
32 rows x 14 tomato plants = 448 tomato plants total
300 zucchini plants + 448 tomato plants = 748 plants total

Answer:
to my knowledge it would be c, 100m.
Step-by-step explanation:
P=2(l+w)=2·(34+16)=100
Answer:
(D) 92 m
Step-by-step explanation:
1. You can solve this using the good old pythagorean theorem: a² + b² = c², since the rectangle is just two right triangles next to each other.
2. For the python theorem, you know that the a and b are the sides of the triangle and the c is the hypotenuse of the triangle
3. In this case, it would be:
16² + b² = 34²
4. Computed squares
256 + b² = 1156
5. Subtraction property of Equality
√b² = √900
6. Square rooted both sides
b = 30
7. Now we know what b is, in this context, this would be the length for length AD and BC.
8. Since the perimeter is the total length of the shape, we do:
16 + 16 + 30 + 30 = 92
So, D is your answer.

(Step by step) -20 > -2x + 4
Answer and Step-by-step explanation:
To solve for x, we need to first add 20 to both sides, and then add 2x to both sides.
2x > 20 + 4
Combine like terms.
2x > 24
Divide each side by 2.
x > 12
So, the answer is:
Any value of x that is greater than 12.

Answer:
Area of the remaining board = 403 cm²
Step-by-step explanation:
Area of the remaining paper board = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
= 28 × 20
= 560 cm²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
= [tex]\frac{1}{2}(3.14)(\frac{20}{2})^2[/tex]
= 3.14 × 50
= 157 cm²
Area of the remaining board = 560 - 157
= 403 cm²

Answer:
It should be 126°.
Step-by-step explanation:
Angles ∠ABE and ∠CBE are supplementary angles and supplementary angles add up to 180°. Since we know that the m∠CBE is 54°, we can subtract 54 by 180 and get the measure for ∠ABE. The results should be 126°. I hope this helps! If this answer is wrong then I would love some feedback on what I did wrong! Thank you!

In ΔABC, the measure of ∠C=90°, the measure of ∠A=39°, and BC = 9.7 feet. Find the length of AB to the nearest tenth of a foot. (please answer correctly I will give brainliest)
Answer:
15.4 ft
Step-by-step explanation:
\sin A = \frac{\text{opposite}}{\text{hypotenuse}}=\frac{9.7}{x}
sinA=
hypotenuse
opposite
=
x
9.7
\sin 39=\frac{9.7}{x}
sin39=
x
9.7
x\sin 39=9.7
xsin39=9.7
Cross multiply.
\frac{x\sin 39}{\sin 39}=\frac{9.7}{\sin 39}
sin39
xsin39
=
sin39
9.7
Divide each side by sin 39.
x=\frac{9.7}{\sin 39}=15.4135\approx 15.4\text{ feet}
x=

9.7
=15.4135≈15.4 feet
Type into calculator and round to the nearest tenth of a foot.

Which point lies on a circle with a radius of 5 units and center at P(6, 1)?
A. Q(1,11)
B. R (2,4)
C. S (4, -4)
D. T(9,-2)
Answer:
B
Step-by-step explanation:
An equation of a circle:
(x - a)² + (y - b)² = r²
(a; b) - a coordinates of a center
r - a radius
r = 5; P(6; 1) ⇒ a = 6 and b = 1
therefore
(x - 6)² + (y - 1)² = 5²
check:
A) Q(1; 11)
L = (1 - 6)² + (11 - 1)² = (-5)² + 10² = 25 + 100 = 125
R = 25
L ≠ R
B) R(2; 4)
L = (2 - 6)² + (4 - 1)² = (-4)² + 3² = 16 + 9 = 25
R = 25
L = R - CORRECT
C) S(4; -4)
L = (4 - 6)² + (-4 - 1)² = (-2)² + (-5)² = 4 + 25 = 29
R = 25
L ≠ R
D) T(9; -2)
L = (9 - 6)² + (-2 - 1)² = 3² + (-3)² = 9 + 9 = 18
R = 25
L ≠ R
Answer: B) R(2; 4).
You are flying a kite. You have let out 2000 feet of string. The sun is directly overhead and is casting a shadow that is 1325 feet from you. How high is the kite? If necessary, round your answer to the nearest foot.
Answer:
1,498 feet in elevation
Step-by-step explanation:
h² + 1325² = 2000²
h² = 2000² - 1325²
h² = 2244375
h ≈ 1498
Carly spends 9 hours each day working at her job. What percentage of her day does she spend at work?
Answer:
37.5%
Step-by-step explanation:
divide 9 by 24 and you get .375 abd then move 2 decimal places to the left to get a percentage
Answer:
Step-by-step explanation:
I know this is probably wrong but
I think she spends 37.8% of her day at work. 100% is the maximum for percentages. 100/24=about 4.2
9x4.2=37.8

A map of Oklahoma uses a scale of 1.25 inches = 50 miles Ig Piedmont and Tulsa are 3.5 inches apart on the map how far is it to go from Piedmont to Tulsa AND Back
Answer:
280 miles
Step-by-step explanation:
It is given that :
Scale : 1.25 inches = 50 miles
In the map the distance between Piedmont and Tulsa is = 3.5 inches
So the actual distance between Piedmont and Tulsa in miles is given by :
1.25 inches = 50 miles
So, 3.5 inches = [tex]$\frac{50 \times 3.5}{1.25}$[/tex] miles
= 140 miles.
So when we go from Piedmont to Tulsa, it is 140 miles and we go back from Tulsa to Piedmont, it is another 140 miles.
Therefore, total distance = 140 + 140
= 280 miles

Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years
Answer:
269277
Step-by-step explanation:
Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years
We solve using the formula for exponential growth
Pt = P( 1 + r)^t
When
P = Initial population = 100000
Pt = Population after time t = x
r = Growth rate = 6%
t = Time in years = 17
Hence:
Pt = 100000( 1 + 0.06)¹⁷
Pt = 100000( 1.06)¹⁷
Pt = 269277.27858
Approximately the population in 17 years = 269,277
