The speed of a train increases from 650 km/hr to 800 km/hr in 5 hours. What is its acceleration?

Answers

Answer 1

Answer:

\overline{a} = \frac{v - v_0}{t} = \frac{\Delta v}{\Delta t}

Step-by-step explanation

i do not really understand but use this formula

= average acceleration

v = final velocity

v_0 = starting velocity

t = elapsed time

~ The car makes a complete revolution in 8 s.
~ The radius of the Ferris wheel is 26 m.
~ If the car is loaded at 0 s, then people are loaded at the lowest height of the Ferris wheel.
~ The maximum height of the Ferris wheel above ground is 40 m.

Answers

Answer:

bruh if your question is

"What is the maximum height of the Ferris wheel? "

its 80m

Step-by-step explanation:

ive looked for the question nd couldnt find it so i sarcificed my grade for yall, welcome

The values of the Ferris wheel.

The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.

Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.

The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.

Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions what is the maximum number of portions she stored

Answers

Given :

Vanessa bought a 30 pound bag of rice she cooked 7.5 pounds of the rice she stores the rest of the rice in 4.5 pound portions.

To Find :

The maximum number of portions she stored.

Solution :

Let, number of portions she stored is n.

Amount of rice left, A = 30 - 7.5 = 22.5 pounds.

Now, number of portions of 4.5 pounds she stored :

[tex]n = \dfrac{22.5}{4.5}\\\\n = 5[/tex]

Therefore, maximum number of portions she stored is 5.

Hence, this is the required solution.

Why does sin54°≈0.809≈cos36° in a right triangle?

A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.

B
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the adjacent leg and the hypotenuse and cos36° is the ratio of the opposite leg and the hypotenuse. In this triangle, the adjacent leg of 54° and the opposite leg of 36° are the same leg in the triangle.

C
54° and 36° are supplementary in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and adjacent leg of 36° are the same leg in the triangle.

D
54° and 36° are supplementary in the same right triangle. sin54° is the ratio of the adjacent leg and the hypotenuse and cos36° is the ratio of the opposite leg and the hypotenuse. In this triangle, the adjacent leg of 54° and opposite leg of 36° are the same leg in the triangle.

Answer:

A

54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.

Step-by-step explanation:

The answer explains itself.

The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are complementary (not supplementary).

Savannah drew a map of Texas for her Geography class. According to Savannah’s map scale, one-
half inch on the map represents approximately 77.5 kilometers. If the actual distance from Austin to El
Paso is approximately 930 kilometers, what is the approximate distance
between Austin and El Paso on Savannah’s map?

Answers

Answer:

6 inches

Step-by-step explanation:

First, take the 930 kilometers and divide it by 77.5 kilometers. You will get 12. This means the distance between Austin and El Paso is 12 one half inches. That is equivalent to 6 inches.

Answers

Answer:

The asnwer is 3x + 12y + 4

Answer:

I think you wrote it wrong but if not here

Step-by-step explanation:

Simplifying

2x + -12y = 4

Solving

2x + -12y = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12y' to each side of the equation.

2x + -12y + 12y = 4 + 12y

Combine like terms: -12y + 12y = 0

2x + 0 = 4 + 12y

2x = 4 + 12y

Divide each side by '2'.

x = 2 + 6y

Simplifying

x = 2 + 6y
