Answer: 130 meters
Step-by-step explanation:
We have to let the "surface of the ocean" be at 0 height.
So,
anything above surface has POSITIVE height
and anything below surface has NEGATIVE height
The albatross is 100 m above, so we can say its height is:
+100 meters
The shark is 30 m below, so we can say its height is:
-30 meters
The difference in height is thus:
100 - (-30) = 100 + 30 = 130 meters

Brian is going to take a flight from Boston, Massachusetts, to San Francisco,
California. The flight leaves Boston at 10:25 p.m. Boston time and arrives in
San Francisco at 6:10 a.m. San Francisco time. If San Francisco is in the
Pacific time zone and Boston is in the eastern time zone, how long is the
flight? Use the following to help you answer the question 12:00p.m. eastern
time = 11:00 a.m. central time = 10:00 a.m. mountain time = 9:00 a.m. Pacific
time.
A. 7 h 45 min
B. 3 h 45 min
C. 10 h 45 min
D. 5 h 45 min
Answer:
C
Step-by-step explanation:
The flight duration is 9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes. The correct option is C.
How to calculate the time?To determine the duration of the flight, we need to calculate the time difference between the departure time from Boston and the arrival time in San Francisco, taking into account the time zone difference.
We know that San Francisco is in the Pacific time zone, which is 3 hours behind the Eastern time zone (where Boston is located). So, when it is 10:25 p.m. in Boston, it is actually 7:25 p.m. in San Francisco.
The arrival time in San Francisco is given as 6:10 a.m. San Francisco time, which is 9:10 a.m. Eastern time (since Pacific time is 3 hours behind Eastern time).
Therefore, the flight duration is:
9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes
So, the answer is C. 10 h 45 min.

The patio shown has an area of 116 square feet. What is the value of h?
Answer:
8 ft
Step-by-step explanation:
if we made this into a rectangle (pretend you chop off one of the triangles and glue it to the other one to make a long rectangle), the length would be 10+4.5, or 14.5. to find what h is, we can just divide 116 by 14.5. our answer is 8.

Selena is flying a kite as shown below. Use the measurements to find how long the kite string is.
16 feet
12 feet
feet
Answer:
20 feet
Step-by-step explanation:
In this case, you'd use pythagoras's theorem (a^2 + b^2 = c^2)
The hypotenuse is always = c, so you'd set up the equation like this:
16^2 + 12^2 = c^2, where you're solving for c (to find out the length of the kite string)
This equation simplifies to 256 + 144 = c^2
which further simplifies to 400 = c^2
to solve for c, we square root both sides so the c is isolated:
[tex]\sqrt{400} = \sqrt{c}[/tex]
20 = c
so the length of the kite string is 20 feet
The required length of the kite string will be 20 feet.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
As per the question, we have to use Pythagoras's theorem
a² + b² = c²
Here hypotenuse = c,
Substitute the known values and we get
16² + 12² = c²,
Here c is the length of the kite string and simplifies the equation as:
256 + 144 = c²
c² = 400
c = √400
c = 20
Thus, the length of the kite string is 20 feet.

Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.
x + y = 166
14x + 22y = 9
x + y = 166, , 14x + 22y = 9,
x + y = 9
22x + 14y = 166
x + y = 9, , 22x + 14y = 166,
x + y = 9
14x + 22y = 166
x + y = 9, , 14x + 22y = 166,
x + y = 36
166x + 9y=14x + 22y
The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Barbie spent $166 on clothes.
The cost of each pant = $22
The cost of each shirt = $14
Total number of items = 9
Now,
Let number of shirts = x
And, The number of pants = y
Since, Total number of items = 9
So, we can formulate;
⇒ x + y = 9
And, The cost of each pant = $22
The cost of each shirt = $14
So, We can formulate;
⇒ $14x + $22y = $166

Step-by-step explanation:
What the information at the top tells us is that triange ABC is an isosceles triangle. In an isosceles triangle the two base angles are congruent, this means that <A=<C. Additionally, because of vertical angles we know that <C is equal to 38. So to find m<B use the expression 180-(2*38). This simplifies to 180-76, which is 104.

I am assuming the question is asking which x value plugged into the function will give you a zero so
(-1)3 -8(-1)2 -23(-1)+30
so that simplyfiys to -1-8(1)+23+30
so that is -1-8+53
so -9+53
= 44
trying 3 we get
(3)3-8(3)2-23(3)+30
so that is 27 -72-69+30
and that is not zero
trying -10
we get
(-10)3-8(-10)2-23(-10)+30
which is -1000- 800+230+30
that is not zero so lastly trying 1 we get
(1)3-8(1)2-23(1)+30

How does the function represented in the table change over equal intervals? What
does this tell you about the type of function it is?
For equal intervals changing in the independent variable, the corresponding dependent value does not change by equal differences, so it is not linear. which is the correct answer would be option (B).
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
The table is given in the question.
As per the given table,
The rate of change will be
During the first interval : (20-10)/(9-7) = 10/2
During the second interval : (30-20)/(11-9) = 10/2
During the third interval : (40-30)/(14-11) = 10/3
The corresponding dependent value does not vary by equal differences when equal intervals in the independent variable change, therefore it is not linear.
Hence, the correct answer would be an option (B).
