A train travels 250 miles at a constant speed (x), in miles per hour.

Archy [21]3 years ago

Answer: 5x=250 , where x is the speed of the train.

Step-by-step explanation:

The formula to calculate speed is given by :-

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

Since, the distance traveled by train = 250 miles

Let x be the speed of the train.

Then, the  equation that can be used to find the speed of the train, if the time to travel 250 miles is 5 hours is given by :-

x=\frac{250}{5}\\\\\Rightarrow\ 5x=250......................[\text{Multiplying 5 on both sides}]

How do you find the area of a triangle?
Firlakuza [10]

with it's formula

Area of Triangle = (1/2)(ab)sin(C) – This formula is used when two sides and the angle in between them are known. It can be obtained from the basic formula, Area of Triangle = 0.5 × base × height. The height with respect to side 'a' can be written in as b×sin(C), where C is the angle between a and b.

Priya and Han both factored the number 80. Priya says they should both get the same answer even if they started with different f
meriva

Answer:

Priya is right.

Step-by-step explanation:

The factors of 80 is 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

The factor pairs of 80 are

1 x 80, 2 x 40, 4 x 20, 5 x 16 and 8 x 10

If Priya picks 2 x 40, then it's prime factorisation will be, 2 x 2 x 2 x 2 x 5 = 2⁴ x 5.

If Han picks, 5 x 16 = 5 x 2 x 2 x 2 x 2 = 5 x 2⁴ = 2⁴ x 5. This is the same.

Therefore, Priya is correct, because the factors of 80 are always the same, therefore which ever you start with, you'd always get the same answer.

HELP WITH 10 QUESTIONS?!?! HERE IS THE FIRST 1.
madreJ [45]
5x - 5y = 10
x - y = 2 . . . (1)
3x - 2y = 2 . . . (2)

(1) x 3 => 3x - 3y = 6 . . . (3)
(2) - (3) => y = -4

From (1), x - (-4) = 2
x = 2 - 4 = -2

Solution is (-2, -4)

24 metal spheres are melted, and the liquid is poured into a rectangular mold. The radius of each sphere is 4 cm. The length of
astra-53 [7]
So first, let's calculate the total volume of all metal spheres.

Total volume = number of spheres * 4/3* πr³
Total volume = 24*4/3*3.14*4³ = 6430.72 cm³

Now, let's equate this to the volume of the rectangular prism. The volume of a rectangular prism is:

V = LWH, where L is the length, W is the width and H is the height

Thus,

6430.72 = (6 cm)(2 cm)(H)
Solving for H,
<em>H = 535.9 cm</em>
