From the top of a 200 foot lighthouse, the angle of depression to a ship on the ocean is 23 degrees.
How far is the ship from the base of the lighthouse?
I know I did it right by the key says its wrong. Please provide steps
the ship is 472 m from the lighthouse
Step-by-step explanation:
from the question, we can know ∠OAS = 90°-23° =67° and AO = 200m
OS = A0 • tan 67°
= 200 m • 236°
= 472 m

The Budget Car Rental rates for renting a car for a day is shown in the table.
a) What is the initial cost of renting a car? (Answer in Blank 1)
b What is the rate of change? (Answer in Blank 2)
c) Using C for the cost of and d for the distance driven, write an equation representing the rental rates of the car agency. (Answer in Blank 3)
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
a.) Initial cost of renting the car is $100
b.) rate of change is slope, that is :
[tex] \dfrac{105 - 100}{100 - 0} [/tex][tex] \dfrac{5}{100} [/tex][tex] \dfrac{1}{20} [/tex][tex]0.05[/tex]c.) Cost = C and distance = d
the equation will be :

Evaluate this expression 33+(-5)-(-70)-26
Answer:
82
Step-by-step explanation:
33 + (-5) - (-70) - 26
33 - 5 + 70 - 26
- and - = +
- and + = -
+ and - = -
33 -5 = 28
28 + 70 = 108
108 - 26 = 82

What is the slope of the line whose equation is 2x-4y=10? Show answers
Step-by-step explanation:
the slope of the line = 1/2
that is the answer
Answer:
y = - 0.5x + 2.5
y = -1/2 + 5/2
Step-by-step explanation:
2x -4y = 10 lets find y
-4y = 10+2x
-4y = 2x-10
-4y/-4 = 2x/-4 - 10/-4
y = - 0.5x + 2.5
y = -1/2 + 5/2

Choose one of the three elements of African culture in colonial North America: food and farming, storytelling, or music and dance. Describe one way African culture influenced your chosen element in the colonies. Explain one way this influence can still be seen today?
Answer:
Music and dance. It's easier in today's society to see black influence over popular music genres, however, this most likely stemmed from African culture, and as you said, in colonial North America. The colonials who enslaved the Africans most likely (i keep using this term so that you can confirm with your own teachings) were influenced by their customs and music (which can include dance) and attempted to integrate it into their own culture. This would trickle down into the future generations through black-dominated genres, such as hip-hop, rap, drill, and dances, such as break dancing, hip-hop (dancing), and the sort.
A company offers you a salary of $2,000 per month plus a signing bonus of $10,000. What is the yearly salary rate? PLEASE HELP!!!!
Since yearly, without the bonus, you would make a certain amount by multiplying $2,000 to a year, which is 12 months.
2000 × 12 = 24,000 a year.
That would be $24,000 a year.
Next, we can add 10,000 to the amount, since you are not getting paid that much for a year. It is just a "...plus...", a bonus.
24,000 + 10,000 = 34000
Therefore, the yearly salary rate will be $34,000 a year.
The table below shows the equations of five lines.
line 1: y= 2x - 3
line 2: 2x + y - 3 = 0
line 3: y= 5x + 11
line 4: 2x - y = 10
line 5: y= 1/2x - 5
a) which line has the greatest slope? explain ur answer.
b) which lines are parallel? show workings and explain
c) which lines are perpendicular? show workings and explain.
d) at which point does line 3 cross the y-axis?
Answer:
a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.
b) line 1 and 4 are parallel because they have the same slope: 2
c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.
d) line three crosses the y line at point 11
Step-by-step explanation:
Line 1. y = 2x - 3
Line 2: y = -2x + 3
Line 3: y = 5x + 11
Line 4: y = 2x - 10
Line 5: y = 1/2x - 5

Find the constant of proportionality in the graph
below.
a. 9
b. 4
C. 3
d. 1.5
The answer is B. Since the graph increases by 4 on the y-axis as x increases by 1, the constant of proportionality is 4.
Stanley's weekly allowance is $5. He can also earn $2 each time he walks the family dog. Write an equation that shows how the amount of money Stanley gets in a week, y, depends on the number of times he walks the dog, x.
Answer:
y = 2x + 5
Step-by-step explanation:
Since he earns $2 for every time he walks the dog, we multiply x by 2
He already starts with $5, so just add 5 to the equation to find y
The ratio of men to women working for a company is 7 to 5. If there are 336 employees total, how many women work for the company?
please answer soon as possiblee!!!
==========================================================
Explanation:
m = number of men
w = number of women
The ratio of men to women is 7 to 5, meaning that m/w = 7/5
Cross multiply to get 5m = 7w.
Then divide both sides by 5 to end up with m = 7w/5 which is the same as m = 1.4w
We'll use this equation later.
------------------
Since there are 336 total workers, we know that:
m+w = 336
1.4w+w = 336 .... replace m with 1.4w
2.4w = 336
w = 336/(2.4)
w = 140 women work at the company
and m = 1.4*w = 1.4*140 = 196 men work at the company as well.
------------------
Checking the answer:
m+w = 196+140 = 336
m/w = 196/140 = (7*28)/(5*28) = 7/5
This helps confirm we have the correct value of w.
Sheila walks 3 miles in 9/10 of an hour. How fast does she walk per hour?
Answer:
1 hours = 60 min
60 x 9/10 = 54 min
3 divided by 54 = 1/18
so she walks 1/18 miles per hour.
Im not sure though. It might be 3 divided by 9/10 = 3 1/3. I’m not that confident in my answer. But it is definitely one of them, either 1/18 or 3 1/3.

SIGMA TELLS US The bottom value is value we start with _vs
SIGMA TELLS US The top value is the term we end with - te
A n-2 turns into 9 which makes 7n-5 become -2+7-5 = 0
B n-12 turns into 12 which makes 7n-5 become -1 +7- 5 = 1 (12 x7=84 and -5+84 = 79)
we can prove by using nth common term 7 x 12 -5 = 79
C n -1 turns into 5 which becomes -1+7 = 6
D n- 1 turns into 5 which becomes -1+7-5 = 1
we see the sequence given is 2, 9, 16 ....79 it is ascending sequence +7
we know the nth term is 7n-5 as we work out first step ( 2 - 7= -5)
we see the term we end with is either 9 12 or 5 and we see the end term given value is 72 so B is our answer.

Answer:
x= -11
Step-by-step explanation:
Rearrange terms
[tex]-1=\frac{5+x}{6} into -1=\frac{x+5}{6}[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]-1=\frac{x+5}{6} \\6(1)=6(\frac{x+5}{6} )[/tex]
Cancel multiplied terms that are in the denominator
[tex]6(-1)=6 (\frac{x+5}{6} )6(-1)=x+5[/tex]
Multiply the numbers
[tex]6(-1)=x+5\\-6=x+5[/tex]
Subtract 5 from both sides of the equation
[tex]-6=x+5\\-6-5=x+5-5[/tex]
Simplify
Subtract the numbers

How many times greater is the elevation of Tammy's house than the elevation of the ocean's surface at 2 p.m.?
Answer:
wouldnt the answer be 9.9
Step-by-step explanation:
12.1-2.2=9.9
Answer:
Step-by-step explanation:
The elevation of Tammy's house is 3 1/2 times the elevation of Winston’s house which is 12.1 and that would give us 42.35 and then subtract the 2pm ocean elevation which is 2.2 and that would leave us with the answer of 42.15. so no the answer is not 9.9
