Answer:
21.75 km/h
Step-by-step explanation:
Let's call the aircraft carrier speed 'x', so the speed of the container ship is 'x+8'
The distance travelled can be found with the product of the speed and the time travelled: d = v * t
The aircraft carrier travelled five hours, so the distance travelled is:
d1 = x * 5 = 5x
Then, the container ship travelled seven hours, so the distance travelled is:
d2 = (x+8)*7 = 7x + 42
As they travelled in opposite directions, the distance between then is the sum of these distances, and it is equal 303 km, so we have that:
d1 + d2 = 303
5x + 7x + 42 = 303
12x = 261
x = 21.75 km/h
Answer:
The aircraft carrier's speed was 13 km/h
Step-by-step explanation:
The parameters given in the question are;
Time of departure of the aircraft carrier = 5 hours before the container ship
Speed of the container ship = 8 km/h faster than the aircraft carrier
Distance between the two ships after 7 hours = 303 km
Let the speed of the aircraft carrier be Z
∴ The speed of the container ship = Z + 8
Since the aircraft carrier left port 35 travelling North 5 hours earlier we have;
Total time of travel of the aircraft carrier at the time of measurement of the distance between the two ships = 5 + 7 = 12 hours
Therefore, since both ships are moving in opposite direction on the same line path, we have;
303 = 12×Z + 7 × (Z + 8) = 12·Z + 7·Z + 56
19·Z = 303 - 56 = 247
∴ Z = 247/19 = 13 km/h
Hence, the aircraft carrier's speed was 13 km/h.

((2ab)/(a ^ - 5 * b ^ 2)) ^ - 3 Which is the simplified form Assume a ne0 b ne0
Answer:
The correct options is (a)
The simplified form of the given expression (2ab/a⁻⁵b²)⁻³ is b³/8a¹⁸. The correct answer is option A.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given as follows:
(2ab/a⁻⁵b²)⁻³
= [(2ab) / (a⁻⁵b²)]⁻³
Use the negative exponent rule: a⁻ⁿ = 1/aⁿ and simplify the denominator
= [(2a.a⁵b) / (b²)]⁻³
Combine the coefficients 1 and 5 to get
= [(2a⁶) / (b)]⁻³
= 1/[(2a⁶) / b]³
= 1/[(2a⁶)³ / b³]
Cube the resulting expression to get
= b³/8a¹⁸
Therefore, b³/8a¹⁸ is the simplified form of (2ab/a⁻⁵b²)⁻³.
Hence, the correct answer is option A.

Answer:
im pretty sure its b
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
When x < 1, y = 1, which is a horizontal line. This eliminates the last 2 options because the red line (which represents x < 1) is not a horizontal line. However, if we look at the second option, we see that the red line is y = 2, not y = 1, and therefore the answer is A. Hope this helps!

Answer: 20,736
Step-by-step explanation:
There are 12 people total in the room, so the base of the exponent will be 12.
Sine there are 4 possible positions, the exponent will be 4.
# of possibilities = 12^4
12^4 = 12 * 12 * 12 *12 = 20,736

Step-by-step explanation:
What is the first step to solve this equation: 3x =44
You need to divide 3 on both sides
The correct first step to solve the equation 3x = 44 is to divide both sides by 3.
To solve the equation 3x = 44, the first step is to isolate the variable x on one side of the equation.
To achieve this, you need to undo the multiplication by 3 on the left side of the equation.
Since 3x means 3 multiplied by x, you need to divide both sides of the equation by 3.
By dividing both sides of the equation by 3, you are essentially canceling out the effect of the multiplication by 3 on the left side.
This step allows you to isolate the variable x.
So, the correct first step to solve the equation 3x = 44 is to divide both sides by 3.
Hence the correct option is 4th.

Find the 8th term in the sequence
-1/2, -1, -2, -4......
Answer:
-64
Step-by-step explanation:
geometric
equation
a1(r)^n-1
-1/2(2)^8
Given sequence is -1/2, -1, -2, -4,...
We get,
a1 = -1/2
r = 2
n = 8
So,
a8 = a.r^(n-1)
a8 = -1/2 * 2^(8-1)
a8 = -1/2 * 2^7
a8 = -1/2 * 128
a8 = -64
Therefore, 8th term of the sequence is -64
