The angle x to the nearest degree is 40°
Given,
The depth of submarine that a ship's sonar detects = 440 feet
The distance from submarine to ship in oceans surface = 600 feet
We have to find the angle x.
The figure is given below:
Here, we have to use the tangents definition:
That is,
tan θ = opposite side / adjacent side
Here,
tan x = 440 / 600
We want to find x,
So,
x = tan⁻¹ (440 / 600)
x = tan⁻¹ (0.73333)
x = 40.28°
By taking nearest angle, we get x as 40°

The monthly rent on an -square-meter apartment in Monte Carlo, Monaco, is $1000 euros. The monthly rent on a 450-square-foot apartment in Santa Fe, New Mexico, is $900. In terms of price per area, which apartment is less expensive?
The apartment in santa fe is less expensive
Rent in an-square-meter apartment in Monte Carlo = 1000 euros.
rent on a 450-square-foot apartment in Santa Fe = $900
To Find:
Which apartment is less expensive =?
Price per area in Monte Carlo
Cost per square meter in Monte Carlo
=>total rent / total area
=>1000/1
=> 1000euros per square meter
Converting to euros per square meter to dollars per square foot
1 Euro per square meter= 0.102355924 U.S. dollars per square foot
1000 euros per square meter = 0.102355924 x 1000 = 102.3559U.S. dollars per square foot------------------------(1)
Price per area Santa Fe, New Mexico

d = 10 inches
r = 5 inches
Now calculating the area of circle using the above formula :
A = πr²
A = π(5)²
A = 25π in.²
2) It is given that radius of circle is 8 cm then calculating area using above formula :
A = πr²
A = π(8)²
A = 64π cm²
Therefore, the area of circle of diameter 10 inches is 25π in.² and,

Answer:
Area of two rooms is 357 square feet
Length of the baseboards = 89.5 ft
Step-by-step explanation:
Area and perimeter of rectangular room:Area of the room = length * width
Area of the two rooms = area of bigger room + area of smaller room
= 19 * 15 + 8 * 9
= 285 + 72
= 357 square feet
To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.
Bigger room:
length = 19 ft
Width = 15 ft
Width of the entry = 2 1/2 ft = 2.5 ft
Width of the opening between two rooms = 5 ft
Perimeter of bigger room = 2l + 2w - 5 - 2.5
= 2*19 + 2*15 - 7.5
= 38 + 30 - 7.5
= 60.5 ft
Smaller room:
length = 8ft
Width = 9 ft
Width of the opening = 5 ft
Perimeter of the smaller room = 2*8 + 2*9 - 5
= 16 + 18 - 5
= 29 ft
Length of the base board = 60.5 + 29
= 89.5 ft

Can someone help me with this?
Answer:
Choice A: 11
Step-by-step explanation:
We have x² - y² = 19
x² - y² = (x + y)(x-y)
So (x + y)(x-y) = 19
Since x and y are integers as per the first statement (x, y ∈ Z), we also have x + y = integer and x-y = integer
Take (x + y)(x - y) = 19
Since 19 is prime its only factors are 1 and 19
So we have two situations which can satisfy the above
Either x + y = 1 and x -y 19 or x + y = 19 and x -y = 1
1. Let's try x + y = 1 and x - y = 19
Adding both equations together gives us 2x = 20 (y-terms cancel)
==> x = 10 ==> 10 + y = 1 or y = -9
So 2x - 9 => 2(10) - (-9) = 20 + 9 = 29
This is not one of the choices so we can go on to the next case
2 Let's take x + y = 19 and x - y = 1
Adding these two equations gives us
2x = 20, x = 10 as before
Use 10 in the equation x + y = 19
==> 10 + y = 19
==> y = 19 - 10 = 9
2x - y ==> 2(10) - 9 ==> 20 - 9 = 11
So answer is choice A: 11

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
5y2 - 8y = 2
The solution of y are 1.82 and -0.22
The general expression for quadratic equation is given as :
ax² + bx + c = 0
The quadratic formula of the above equation is given as
x = -b ± √b²-4ac / 2a
According to the question we have been the expression as
5y² - 8y = 2
Converting it into general expression we get
5y² - 8y - 2 = 0
Putting the required value in above quadratic formula we get
y = -(-8) ± √(8)² - 4*5*(-2) / 2*5
y = 8 ± √64 + 40 / 10
y = 8 ± √104 / 10
y = (8 ± 10.2)/10
y = 8 + 10.2 / 10 and y = 8-10.2 / 10
y = 18.2 / 10 and y = -2.2/10
y = 1.82 and y = -0.22

Question: When time equals 0, why is the height of the cannon ball not equal to 0? Describe the domain of this function. Describe the range.
The height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground
When time equals 0, why is the height of the cannonball not equal to 0?From the graph, we have the y-intercept to be
y-intercept = (0, y), where y > 0
This means that the graph starts above the origin
This in other words mean that the initial height of the cannonball is above the ground (e.g. it could be on a building)
Hence, the height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground

If JK = x + 8, KL = 10, and JL = 7x, what is JK?
Answer:
10 is the jk because x + 8 is 10
I hope it will help
Answer:
11 units
Step-by-step explanation:
It's clear that,
JL = JK + KL
Given that,
JK ⇒ ( x + 8 )
KL ⇒ 10
JL ⇒ 7x
So, by using these data we can make an expression like this.
JL = JK + KL
7x = x + 8 + 10
Now make x the subject and find the value of x.
7x = x + 8 + 10
7x = x + 18
7x - x = 18
6x = 18
6x/6 = 18/6
x = 3
And now let us find the value of JK.
JK ⇒ x + 8
To, find the value of JK we have to replace with 3.
JK ⇒ x + 8
JK ⇒ 3 + 8
JK ⇒ 11 units

2(4x - 3) - 8 = 4 + 2x
Answer: x=3
Step-by-step explanation:
2(4x - 3) - 8 = 4 + 2x
8x - 6 - 8 = 4 + 2x
8x - (6 + 8) = 4 + 2x
8x - 14 = 4 + 2x
8x - 14 + 14 = 4 + 14 + 2x
8x = 18 + 2x
8x - 2x = 18 + 2x - 2x
6x = 18
6x/6=18/6
x=3
x = 3
first you want to distribute 2 to 4x and -3
8x-6 -8 = 4 +2x
then you subtract the numbers on the left side
8x-6-8
8x-14= 4 +2x
then we want to rearrange the 4 and 2x
8x - 14 = 2x+4
the add 14 to each side and move 2x to both sides
6x=18
then divide
x=3

Step-by-step explanation:
Find three consecutive even integers such that the square of the third is 52 more than the square of the second.
The Three consecutive numbers will be 24.5, 25.5, 26.5
We have to take three consecutive numbers. Let the first number be 'x' and the consecutive two numbers be (x + 1), and (x + 2).
It is given that the square of the third number is greater than the square of the second number by 52. We need to create an equation that represents this situation. So, we get :
=> (x + 2)² = (x + 1)² + 52
=> x² + 4x + 4 = x² + 2x + 1 + 52
=> x = 49/2 => x = 24.5
We get value of x = 24.5. Putting this value of x in consecutive numbers we get the first, second, and third numbers as 24.5, 25.5, and 26.5 respectively.
Hence, we get the three consecutive numbers: 24.5, 25.5, and 26.5

What is compound inequality?A compound inequality has two inequality statements joined either by the "or" or “and.”
We have,
6x+2y<12 or x-6y>6
We can graph each inequality.
And we also need to see the intersection between the inequalities.
Let,
6x + 2y = 12____(1)
x - 6y = 6_______(2)
From (1)
x = (12 - 2y ) / 6 put in (2)
(12 - 2y) / 6 - 6y = 6
2 - 1/3y - 6y = 6
2 - 6 = (1/3)y + 6y
-4 = 19y / 3
y = -12 / 19
y = - 0.63 put in (1)
6x + 2 x (-0.63) = 12
6x = 12 + 1.26
x = 13.26 / 6
x = 2.21
