Solve the inequality.
X/10 >5

Answer: 4/5 and 5/6 are not equivalent to 2/3 because they represent different fractions. 4/5 represents 4 parts out of 5 total parts, while 5/6 represents 5 parts out of 6 total parts. 2/3 represents 2 parts out of 3 total parts. To check if two fractions are equivalent, you need to see if they simplify to the same fraction. For example, 4/5 simplifies to 8/10 and 5/6 simplifies to 5/6, but neither of them simplifies to 2/3. Hence, 4/5 and 5/6 are not equivalent to 2/3.

Step 1: Calculate the circumference of the circle.

Circumference = 2πr

Where 'r' is the radius of the circle.

Since we know the center of the circle is point A, we can calculate the radius of the circle by measuring the distance from point A to any point on the circumference.

Let's say we measure the distance from point A to point B.

Radius = AB = x

Step 2: Calculate the circumference of the circle.

Circumference = 2πx

Step 3: Calculate the length of arc bcp.

We know that the length of arc bcp is 2/5 of the circumference of the circle. So,

Length of arc bcp = (2/5) × (2πx)

Length of arc bcp = (4πx)/5

Step 4: Solve for x.

To solve for x, we will rearrange the equation:

(4πx)/5 = Length of arc bcp

5 × (4πx)/5 = 5 × Length of arc bcp

4πx = 5 × Length of arc bcp

4πx = 5 × (2/5) × (2πx)

4πx = 4πx

Since both sides of the equation are equal, x = x.

Therefore, the value of x is equal to itself.

The average velocity of the object from t = 2 and t = 4 is equal to - 48 feet per second.

In this problem we find the case of an object thrown upward, whose height (h(t)), in feet, as a function of time (t), in seconds, is represented by a quadratic equation. We need to determine the average velocity (u) of the object by means of secant line formula:

u = [h(4) - h(2)] / (4 - 2)

Where:

If we know that h(t) = - 16 · t² + 48 · t + 120, then the average velocity is:

t = 2

h(2) = - 16 · 2² + 48 · 2 + 120

h(2) = 152 ft

t = 4

h(4) = - 16 · 4² + 48 · 4 + 120

The wires are to be secured to the ground 22 feet from each other.

BD = 22 ft

We need to find angle that must the 14-foot long wire make with the ground i.e., angle ACD

Using law of cosines,

c² = a² + b² - 2ab. cos(x)

where x = ∠ABD

c is the opposite side of angle x

a and b are adjacent sides of angle x

here,  c = 17, a = 14, and b = 22

Substitute these values in above formula,

Answer:

During winter in the Arctic, a lake gets frozen solid with ice. But as spring comes, the ice starts to melt. This happens because the temperature gets warmer and there's more sunlight. It's a natural process that happens every year and shows the change of seasons.

Step-by-step explanation:

Answer: The given equation is Y = -10x + 300.

The rate of change of this equation refers to the rate at which Y changes as x changes. This is the same as the slope of the line represented by the equation.

The equation is in the form of y = mx + b, where m is the slope and b is the y-intercept. So, we can see that the slope of the line is -10. This means that for every one unit increase in x, y decreases by 10 units.

Therefore, the rate of change of Y with respect to X is -10.

The maximum height of the ball is 200 feet.

An expression can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.

To find the time to the highest point, we need to find the time when the velocity of the ball is equal to zero. The velocity of the ball can be found by taking the derivative of the height equation with respect to time.

The derivative of h with respect to t is:

dh/dt = 32t + 64

Setting the derivative equal to zero and solving for t, we get:

0 = 32t + 64

-64 = 32t

t = -2

So, the time to the highest point is -2 seconds. However, since time cannot be negative in this context, we can say that it takes 2 seconds for the ball to reach its highest point.

To find the maximum height, we can substitute the time of 2 seconds back into the original height equation:

h = 16(2)^2 + 64(2) + 8

h = 64 + 128 + 8

h = 200

So, the maximum height of the ball is 200 feet.

x + 3.5x = £48

Next, we'll simplify the left side of the equation by combining like terms:

4.5x = £48

By applying Algebraic fractions simplifying concept, it can conclude that the simplified expression is - (9p + 3) / q.

Algebraic fractions simplifying can be done by factoring the quantifier and denominator, then dividing by the common factors of the quantifier and denominator.

We have the following algebraic fraction:

((9p² - 1) / (pq - 2q)) / (1 - 3p) / (3p - 6)

To simplify this expression, we will do the following steps:

First, we apply the division rule: (a/b) / (c/d) = ad / bc:

    ((9p² - 1) / (pq - 2q)) / (1 - 3p) / (3p - 6)

⇔ ((9p² - 1) (3p - 6)) / ((pq - 2q) (1 - 3p))

Then we find the factors of (9p² - 1), that are (3p - 1) (3p + 1):

⇔ ((3p - 1) (3p + 1) (3p - 6)) / ((pq - 2q) (1 - 3p))

Factor other expressions that are not already factored in:

⇔ ((3p - 1) (3p + 1) 3 (p - 2)) / (q (p - 2) (1 - 3p))

Now we cancel the common factor (p - 2), so we have:

⇔ (3 (3p - 1) (3p + 1)) / (-q (3p - 1))

Then we cancel the common factor (3p -1), so we have:

⇔ (3 (3p + 1)) / -q

Finally, we expand the expression:

⇔ - (9p + 3) / q

Thus the simplified expression is - (9p + 3) / q.

The proportion of vehicles travelling less than 50 mph is 0.1587, as it is the area under the normal curve from 0 to 50 mph.

The speed of vehicles travelling along a stretch of I-10 is assumed to have an approximately normal distribution with a mean of 71 mph and a standard deviation of 8 mph. This means that the majority of vehicles will travel at speeds close to the mean, with fewer vehicles travelling at speeds significantly above or below the mean. To calculate the proportion of vehicles travelling less than 50 mph, we must calculate the area under the normal curve from 0 mph to 50 mph. This is done using a z-score, which is calculated by subtracting the mean from the value and dividing by the standard deviation. In this case, the z-score for 50 mph is -1.375.
