A shark is swimming 42 feet below sea level. If the angle of depression from a boat on the water to the shark is 23°, what is the horizontal distance between the boat and the shark? Show your work to receive full credit. Round to the nearest hundredth if necessary.
Answer:
BC ≈ 98.95 feet
Step-by-step explanation:
From the figure attached,
A shark is swimming 42 feet below sea level at point A and a boat on the water is at point C.
If the angle of depression from the coat to shark is 23°,
tan(23°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(23°) = [tex]\frac{AB}{BC}[/tex]
BC = [tex]\frac{AB}{\text{tan}(23)}[/tex]
BC = [tex]\frac{42}{\text{tan}23}[/tex]
BC = 98.947
BC ≈ 98.95 feet
How long will it take for a certain population of fish to triple if the relative growth rate is 45% per year?
Answer:
n = 3 Year (Approx)
Step-by-step explanation:
Given:
Growth rate (r) = 45% = 0.45
Find:
Number of year for 3 times of population (n)
Computation:
Assume;
Current population = P
So,
New population = 3P
A = p(1+r)ⁿ
3P = P(1+0.45)ⁿ
3 = (1.45)ⁿ
n = 2.96 year
n = 3 Year (Approx)

Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?
A. $8.70
B. $7.25
C. $14.50
D. $29
Christ spent a total amount of $ 14.50 on the shirt.
Finding the amount spent on the shirt
Here we use the linear equation concept to solve the problem.
Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.
Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below
Here we have
Christy spent 2/5 of her money on a shirt.
She has $21.75 left
Let 'x' be the amount that Christy has
From the data,
Christy spent 2/5 of her money on a shirt.
Amount spent by Christy = 2/5 of x = 2x/5
Remaining amount = x - 2x/5
From the data,
Chrisy is left with $ 21.75
=> x - 2x/5 = 21.75
=> 3x/5 = 21.75
=> 3x = 108.75
=> x = 36.25
Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50
Therefore,
Christ spent a total amount of $ 14.50 on the shirt.

How many pounds are in 6 tons, 200 pounds
Answer:
there are 12000 pounds in 6 tons
There are 12,200 pounds in 6 tons, 200 pounds .
To convert tons to pounds, we need to multiply the number of tons by the conversion factor of 2,000 pounds per ton .
A ton, also referred to as a short ton, is a unit of weight equal to 2,000 pounds .
Given that there are 6 tons and 200 pounds, we can calculate the total weight in pounds as follows :
6 tons * 2,000 pounds/ton + 200 pounds = 12,000 pounds + 200 pounds = 12,200 pounds .
Therefore, there are 12,200 pounds in 6 tons, 200 pounds .

Two similar triangles are shown. What is the measure of ∠P?
Answer:
68.2
Step-by-step explanation:
if the triangles are similar then all of the angles are the same. The only thing that changes is the side lengths.
Answer:
[tex]63.2[/tex]°
Step-by-step explanation:
since the triangles are similar they have identical angle measures are the same
however you could solve it this way too:
[tex]A+B+C=180[/tex]
all measures of a triangle add up to 180
[tex]23.8+90+C=180[/tex]

2x+4y=1
3x+5y=7
Answer:
x = 11.5, y = -5.5.
As an ordered pair this is (11.5, -5.5).
Step-by-step explanation:
2x+4y=1 Multiply this by 3:
3x+5y=7 Multiply this by -2.
6x + 12y = 3
-6x - 10y = -14 Adding these 2 equations:
0 + 2y = -11.
y = -11/2
y = -5.5.
Now plug this into the first equation:
2x + 4(-5.5) = 1
2x = 1 + 22
x = 23/2
x = 11.5.
