A plane flies 1890 km in 3.5 hours. How far will the plane fly in 4.2 hours if it maintains the same air speed?
Answer:
2267 km
Step-by-step explanation:
1890 km/3.5 hours = 2267 km/4.2 hours
2268 km far will the plane fly in 4.2 hours if it maintains the same air speed.
How far will the plane fly in 4.2 hours if it maintains the same air speed?
The formula speed = distance ÷ time can be rearranged like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.
Given,a plane flies 1890 km in 3.5 hours.
So, distance = 1890 km and time = 3.5 hours.
We know,
Distance = Speed × Time
For example, If speed of a car is 20 m/s and the car travel 60 s then the car cover total distance
[tex]= 20 \times 60 = 1200 \: m[/tex]
Again
[tex]speed = \frac{distance}{time}[/tex]
According to question,
Speed
[tex] = \frac{distance}{time} \\ = \frac{1890}{3.5} \\ = 540 [/tex]
So, speed of the plane is 540 km/hour.
Again given time is 4.2 hours
So, Distance = Speed × Time
[tex] = 540 \times 4.2 \\ = 2268 \: km[/tex]

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.
0.2 inches
4.5 inches
46.1 inches
414.7 inches
Answer:
Width of the rectangular prism
It is given to us that the volume of the rectangular prism is calculated by the given formula :-
v = lwh
Where,
v = volume
l = length
w = width
h = height
Now,
In the question we are given :-
v = 138.24 cubic inches
h = 9.6 inches
l = 3.2 inches
w = ?
Substitute these values in the volume formula given :-
138.24 = 3.2 * w * 9.6
138.24 = 30.72 * w
w = 138.24/30.72
w = 4.5
⇒ The width of the rectangular prism is 4.5 inches.
The required width of the rectangular prism is 4.5 inches.
Given information:
The volume of the rectangular prism is defined as,
[tex]V=lwh[/tex]
where l is the length, w is the width, and h is the height of the prism.
The volume of the prism is 138.24 cubic inches.
The height of the prism is 9.6 inches, and the length of the prism is 3.2 inches.
So, the width of the prism can be calculated as,
[tex]V=lwh\\138.24 =3.2\times w\times 9.6\\138.24 =30.72\times w\\w=\dfrac{138.24}{30.72}\\w=4.5\rm \; inch[/tex]
Therefore, the required width of the rectangular prism is 4.5 inches.

the ski team needs new uniforms. The students plan to sell plush toy eagles (the school mascot) for $5 each. The students find three companies online that sell stuffed mascots. Company A sells 18 eagles for $49.32. Company B seels 16 eagles for $43.36. Company C charges $41.55 for 15 eagles. Which company has the best to buy?
Answer:
Step-by-step explanation:
Company A = 18 eagles for $49.32
Price per eagle = $49.32 / 18
= $2.74
Company B = 16 eagles for $43.36
Price per eagle = $43.36 / 16 eagles
= $2.71
Company C = $41.55 for 15 eagles
Price per eagle = $41.55 / 15 eagles
= $2.77
The company which has the best buy is company C, they sell 1 eagle for $2.77 (highest selling price among the three companies)

What is the x intercept of the line 6x - 5y = 12?
Answer:
2,0
Step-by-step explanation:
6x-5y=12
subtract 6x from both sides.
-5y=-6x+12
divide -5 on both sides.
y=6/5x-12/5
Answer:
x = 2 ⇒ point (2, 0)
Step-by-step explanation:
The x-intercept is the place where the line crosses the x-axis. This is also when y = 0.
So, set y equal to 0 and solve for x:
6x - 5y = 12
6x - 5 * 0 = 12
6x = 12
x = 12/6 = 2
The x-intercept, thus, is at x = 2.
