Answer:
Aircraft carrier speed = 4.97 km/h
Step-by-step explanation:
Given that the time taken by the aircraft = 5 hours
Let the distance covered = X
Speed = V
Time taken by the ship = 7 hours
Let the distance covered = Y
Speed = 8V
Since it is 8 km/h faster than the aircraft carrier.
Using the speed formula
Speed = distance/time
Distance = speed × time
For the aircraft;
X = 5V
For the ship:
Y = 7 × 8V = 56V
Since they are 303km distance apart,
X + Y = 303
5V + 56V = 303
61V = 303
V = 303/61
V = 4.97 km/h
Aircraft carrier speed = 4.97 km/h

If the volume of the pyramid is 72 centimeters cubed, what is its height in cm?
A rectangular pyramid with a base of 6 centimeters by 4 centimeters and a height of h.
A) 3
B) 9
C) 12
D) 18
Answer:
Well, Your best answer will be is B) 9.
Because,
The volume of the pyramid is:
v = (w × h × l)/3
Then, We have to values together:
72 = (4 × 6 × h)/3
Well, Then we have to solve the h:
72 × 3 = (4 × 6 × h)/3 × 3
216 / 6 = (4 × 6 × h)/6
36/4 = (4 × h)/4
9 = h
So, The best answer will be is 9.
Good Luck!~

The height of the pyramid is 9 cm.
What is a pyramid?A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.
The volume of a pyramid with a square base is given as:
Volume = 1/3 x base area x height
We have,
The volume of a rectangular pyramid is given by the formula:
V = (1/3)Bh
Where B is the area of the base and h is the height.
In this case,
The base has dimensions of 6 cm by 4 cm, so its area is B.
= 6 cm x 4 cm
= 24 cm².
We are given that the volume of the pyramid is 72 cm³, so we can plug in these values to get:
72 cm = (1/3)(24 cm²)(h)
Simplifying this equation.
72 cm³ = 8 cm² x h
9 cm = h
Therefore,
The height of the pyramid is 9 cm.

Tom found out that 3 L of fruit punch serves 8 people. He wants to make enough for 48 people. How many liters of punch does he need
Answer:
18
Step-by-step explanation:
Use a proportion
[tex]\frac{3}{8}[/tex]=[tex]\frac{x}{48}[/tex]
8*6=48
So if we multiply 3*6, we get how many liters it takes to serve 48 people
3*6=18
The answer would be 18 L
You do this by doing 48/8= 6
The reason you do 48 / 8 is because you you want to find out how many liters you need so if a 3L serves 8 people you would have to divid 48 into 8. (hope that makes since)
6 x 3 = 18L
Then take the 6 and times that by the 3 getting a total of 18 liters
(Hope this makes since :D)

Monte's Autorana is having an end-of-year clearance in which the TV ads proclaim that
all cars are sold at 5% markup over the dealer's cost. Monte has a new Exfinity for sale
for $18,970. On the Internet, you find out that this particular model has a dealer cost of
$17,500. Is Monte being honest in his advertising?
Answer:
No
Step-by-step explanation:
We first write out $17,500 as a multiplication to 5%
New price = 17500 x 1.05 = 18375 = $18,375
18375-17500 = 875
We then work out the tax on just the mark up of $875 increase
20% mark up = 875 x 0.20 = 175
18.375+175 = 18550
= $18,550 charge to be considered for 5%
However Monte would argue that tax on tax also applies to 875 x 1.20 = 1050
=$1050 and he is just asking to meet half tax costs an extra 10% of his own tax back of 17.500 x 20% that he paid = 17500 x 0.20 = 3500
tax he paid inclusive or non inclusive would be the same.
= $3500
10% of this = 3500 x 0.10 = 350
18550+350 = 18,900
Therefore it is not dishonest if mentioned in the terms and conditions.
We also universally can round 5% up by applying other charges to include promotion costs and even apply more for administration costs.

Which equation has a constant of proportionality equally to 2? PLS HELP I WILL MARK AS BRAINLIEST
Hello there!
A would be the correct answer since 10 divided by 5 equals 2 and so it would be 2x.
B is wrong since it has a constant of proportionality equal to 1.
C is wrong since it has a constant of proportionality equal to 1/2.
D is wrong since it has a constant of proportionality equal to 11.
Answer:
A
Step-by-step explanation:
The equation of proportional quantities is
y = kx ← k is the constant of proportionality
A
y = [tex]\frac{10}{5}[/tex] x = 2x ← with k = 2
B
y = [tex]\frac{2}{2}[/tex] x = x ← with k = 1
C
y = [tex]\frac{2}{4}[/tex] x = [tex]\frac{1}{2}[/tex] x ← with k = [tex]\frac{1}{2}[/tex]
D
y = [tex]\frac{22}{2}[/tex] x = 11x ← with k = 11
Thus A is the required equation
