An aircraft carrier left Hawaii traveling west seven hours before a container
ship. The container ship traveled in the opposite direction going 5 km/h slower
than the aircraft carrier for six hours after which time the ships were 540 km apart.
Find the aircraft carrier's speed.
Answers
Answer:
so speed of aircraft carrier is 30. thank you
The speed of an aircraft carrier is 30 km/h.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, An aircraft carrier left Hawaii traveling west seven hours before a container ship. The container ship traveled in the opposite direction going 5 km/h slower than the aircraft carrier.
Since,
Speed = distance/time
time is 13 hours, 7 hours before the container ship left then the 6 hours container traveled.
Let "s" be the speed of the aircraft carrier
=> d = 13s
Container ship:
time is 6 hours
speed is 5 km/h slower, so s-5
=> d = 6(s-5)
Since they are going in opposite directions, add up the distances to find how far apart they are
=> 13s + 6(s-5) = 540
Now solve for s-
=> 13s +6s -30 = 540
=> 19s = 570
=> s = 30
therefore, the Aircraft carrier was traveling at the speed of 30 km/h and the container ship at the speed of 25 km/h.

1. Using the figure below to answer the question. If the sector (APB) has an area of 7pi and m<APB = 44°, find the radius length for circle P. (answer choices are 6.35, 9.27, 7.57, and 9.7)
Answers
Answer:
7.57
Step-by-step explanation:
the area = 44/360 × π × r²
7 π = 44/360 × π× r²
eliminate π
7 = 44/360 x r²
r² = 7× 360/44
r² = 57.27
r =√57.27 = 7.57

Answers
Answer:
D. 216/625Step-by-step explanation:
The length of the segment JM is 25 units.The segment JL is between 0 and 12, so is 12 units.The segment KL is between 5 and 12, so is 7 units.The probabilities for each point:
P(point on JL) = 12/25P(point not on KL) = 1 - 7/25 = 18/25Required probability:
P = 12/25*18/25 = 216/625Correct choice is D
f=vu÷v+t,find v if f=20 and u=5
Answers
Answer:
v=20/3
See IMAGE FOR SOLUTION
In the given expression f = uv /(v+t) value of v in terms of t is *4/3t.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given an expression f = uv /(v+t)
Also given
f = 20
u = 5
Hence, From the expression
f = uv /(v+t)
=> 20 = 5v/(v + t)
Simplifying in the terms of v
20v + 20t = 5v
15v = -20t
v = -4/3t
Therefore, the value of v in the given expression is -4/3t.

Answer: the equation is y = -5x/6 - 2
Step-by-step explanation:
x1 = -6
y1 = 3
x2 = 6
y2 = -7
now
m(slope) = rise/run = (y2-y1)/(x2-x1)
= (-7-3)/(6-(-6))
= -10/12
= -5/6
now
y = mx+ b
-7 = m*6 + b
or, -7 = -5/6*6 + b
or, -7 = -5 + b
so, b = -2
now
y = mx +b
y = -5/6*x + (-2)
y = -5x/6 - 2
Answer:
y = -5/6 × x - 2 = -5x/6 - 2
Step-by-step explanation:
we have two marked points with seemingly integer coordinates for x and y.
the equation of a line is
y = a×x + b
now, we only need to put the x and y values pairs into this equation and calculate a and b.
P1 = (-6, 3)
P2 = (6, -7)
based on what I can see on the picture.
starting with P1
3 = a×-6 +b
b = 3 + a×6
then with P2
-7 = a×6 + b = a×6 + 3 + a×6 = a×12 + 3
-10 = a×12
a = -10/12 = -5/6
=>
b = 3 + a×6 = 3 + -5/6 × 6 = 3 - 5 = -2
so, the line equation is
y = -5/6 × x - 2 = -5x/6 - 2

What is 6 tenths, 2 hundredths, 8 thousandths in standard form?
A.0.0628 B.0.628 C.6.28 D.628
Answers
Answer:
B: 0.628
Step-by-step explanation:
Place value rules.
The value of each digit in a number is known as the place value. The number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628. The correct option is B.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10Given 6 tenths, 2 hundredths, 8 thousandths, this can be written in the standard form as,
Standard form = 0.6 + 0.02 + 0.008 = 0.628
Hence, the number that has 6 tenths, 2 hundredths, and 8 thousandths can be written in the standard form as 0.628.
