Step-by-step explanation:
A destroyer on patrol spots an aircraft at an altitude of 10,000 ft and an angle of elevation of 20⁰. How far is the aircraft from the ship?
Round to the nearest whole number.
[tex]sin= \frac{opp}{hyp} \\\\sin (20) = \frac{10000}{hyp}\\\\hyp= \frac{10000}{sin(20)} \\\\hyp= 29238 ft[/tex]
The aircraft is 29238 ft from the ship
//
Note: this is based on my assumption that we are looking for the hypotenuse.
If we are looking for the adjacent side, then the answer would be 27475 ft.

Halla el Perímetro y Area de las siguientes figuras: 1) Triángulo de lados 6 cm × 8 cm × 5 cm, con base en 8cm y altura de 3,73 cm. 2) Circunferencia de diámetro 4,5 cm.
Answer:
1) El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²
2) La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²
Step-by-step explanation:
El perímetro es una medida de la distancia alrededor de una figura y el área da una idea de qué tanta superficie cubre dicha figura.
Entonces, el perímetro es la medida obtenida como resultado de la suma de los lados de una figura geométrica plana. Es decir, el perímetro es lo que mide el contorno de la figura.
El área de un triángulo es igual a base por altura dividido por 2.
Siendo r el radio de la circunferencia, el perímetro será calculado como:
P=2*π*r
y el área será:
A=π*r²
1) En este caso, el perímetro es calculado como:
P= 6 cm + 8 cm + 5 cm= 19 cm
Y el área del triángulo es calculada como:
[tex]A=\frac{base*altura}{2} =\frac{8 cm*3.73 cm}{2}[/tex]
A= 14,92 cm²
El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²
2) Siendo el diámetro un segmento de recta que va desde un punto de la circunferencia a otro y pasa por el centro del círculo y l radio la distancia desde el centro del círculo hasta un punto de la circunferencia, entonces, el radio es la mitad del diámetro.
Siendo el diámetro de la circunferencia 4,5 cm, entonces el radio r tiene un valor de 2,25 cm.
Entonces el perímetro será calculado como:
P=2*π*2,25 cm
P= 14,14 cm
y el área será:
A=π*(2,25 cm)²
A= 15,90 cm²
La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Which fraction has a repeating decimal as its decimal expansion?
3/25
3/16
3/11
3/8
how do you solve 3 divided by x -1 = x + 1
Answer:
multiply (x-1) to both sides and then subtract three from both sides
3 = (x-1)(x+1)
3 = (x^2 -1)
0 = x^2 - 4
(x-2)(x+2) = 0
x = 2
x = -2

he airplane Li’s family will be flying on can seat up to 149 passengers. If 96 passengers are currently on the plane, which inequality can be used to determine how many more people can board?
96 + x Less-than-or-equal-to 149
96 + x Greater-than-or-equal-to 149
96 + x > 149
96 + x < 149
This is the same as saying "96 + x less than or equal to 149"
====================================================
Explanation:
We start with 96 people already on board. We add on x more people. The x is a placeholder for a positive whole number.
In total, we have 96+x people on the plane. This total must not exceed the max capacity of 149. In other words, the largest value of 96+x is 149.
Since 96+x can be 149 or smaller, we can say 96+x ≤ 149

Plz help me with all of them plz I will give 65 points
Answer:
7. adjacent (next to each other)
8. vertical (right across from each other)
9. vertical (right across from each other)
10. neither
11. adjacent (right next to each other)
12. neither
Before I go on: all these angles have the same measure as the one across, so ∠SYX has the same measure as ∠UYV (76°), ∠XYW has the same measure as ∠TYU (40°), and ∠WYV has the same measure as ∠SYT (64°)...
13. ∠SYX = 76°
14. ∠XYW = 40°
15. ∠WYV = 64°
These last three are angles added together. They look tricky, but you just note the endpoints and add the measures of the included angles together.
16. ∠SYW = ∠SYX + ∠XYW = 76° + 40° = 106°
∠SYW = 106°
17. ∠TYX = ∠SYX + ∠SYT = 76° + 64° = 140°
∠TYX = 140°
18. ∠VYX = ∠WYV + ∠XYW = 64° + 40° = 104°
∠VYX = 104°
I hope this helps you understand the concept! Have a great day!
The school production of 'Our Town' was a big success. For opening night, 391 tickets were sold. Students paid $4.00 each, while non-students paid $6.00 each. If a total of $1786 was collected, how many students and how many non-students attended?
Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280

In a survey conducted on 200 people, it was found that 105 of them prefer coffee, 50 prefer
tea and the remaining prefer both. Find the fraction of people who prefer both tea and coffee.
Given:
Total number of people = 200
People who prefer coffee = 105
People who prefer tea = 50
The remaining prefer both.
To find:
The fraction of people who prefer both tea and coffee.
Solution:
The number of remaining people who prefer both tea and coffee is
Remaining people = Total number of people - People who prefer coffee - People who prefer tea
Remaining people = 200 - 105 - 50
= 45
Now, the fraction of people who prefer both tea and coffee is
[tex]\text{Required fraction}=\dfrac{\text{Remaining people}}{\text{Total number of people}}[/tex]
[tex]\text{Required fraction}=\dfrac{45}{200}[/tex]
[tex]\text{Required fraction}=\dfrac{9}{40}[/tex]
Therefore, [tex]\dfrac{9}{40}[/tex] of people prefer both tea and coffee.
Susan Carver will purchase a home for $190000. She will use a down payment of 18% and finance the remaining portion at 4.2%, compounded monthly for 30 years
Answer:
$548053.69
Step-by-step explanation:
Cost of home = $190000
Down payment = 18%
Loan amount = (1 - 0.18) * 190000 = $155800
Rate, r = 4.2% = 0.042 ; compounded monthly for 30 years
Using the relation :
A = P(1 + r/n)^nt
n = number of compounding times per period = 12
A = 155800(1 + 0.042/12)^(12 * 30)
A = 155800(1.0035)^360
A = 155800 * 3.5176745
A = 548053.69
Final loan amount = $548053.69

Answer:
y = 4
x = 5
y = 2
x = 1
x = 8
Step-by-step explanation:
to find y-intercepts, set x = 0
to find x-intercepts, set y = 0
1.) 4(0) + 5y = 20
5y = 20
y = 4 -------> y-intercept
2.) 4x + 5(0) = 20
4x = 20
x = 5 -------> x-intercept
3.) 2(0) + y = 2
y = 2 -------> y-intercept
4.) 2x + 0 = 2
x = 1 -------> x-intercept
5.) x - 2(0) = 8
x = 8 -------> x-intercept
Answer:
4x+5y=20 the answer is below
x= −5/4y+5
y= −4/5x+4
2x+y=2 the answer is below
x= −1/2y+1
y=−2x+2
x-2y=8 the answer is below
x=2y+8
y=1/2x−4
Step-by-step explanation:
Let's solve for x.
4x+5y=20
Step 1: Add -5y to both sides.
4x+5y+−5y=20+−5y
4x=−5y+20
Step 2: Divide both sides by 4.
4x/4 = −5y+20/4
x= −5/4y+5
Answer:
x= −5/4y+5
Let's solve for y.
4x+5y=20
Step 1: Add -4x to both sides.
4x+5y+−4x=20+−4x
5y=−4x+20
Step 2: Divide both sides by 5.
5y/5 = −4x+20/5
y= −4/5x+4
Answer:
y= −4/5x+4
Let's solve for x.
2x+y=2
Step 1: Add -y to both sides.
2x+y+−y=2+−y
2x=−y+2
Step 2: Divide both sides by 2.
2x/2= −y+2/2
x= −1/2y+1
Answer:
x= −1/2y+1
Let's solve for y.
2x+y=2
Step 1: Add -2x to both sides.
2x+y+ −2x=2+ −2x
y=−2x+2
Answer:
y=−2x+2
Let's solve for x.
x−2y=8
Step 1: Add 2y to both sides.
x−2y+2y=8+2y
x=2y+8
Answer:
x=2y+8
Let's solve for y.
x−2y=8
Step 1: Add -x to both sides.
x−2y+−x=8+−x
−2y=−x+8
Step 2: Divide both sides by -2.
−2y −2=−x+8−2
y=1/2x−4
Answer:
y=1/2x−4
