The equation that represents the given sitution is 3a-6 = 69. Rita saved $25.

What is an epression?

A number, a variable, or a combination of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.

Assume that Rita saved $a.

Given that the cost of a skateboard is $6 less than three times what she has saved.

The mathematical expression of $6 less than three times what she has saved is 3a-6

The actual cost is $69.

According to the question,

3a-6 = 69

Add 6 on both sides:

3a = 69 + 6

3a = 75

Divide both sides by 3:

a = 75/3

a = 25

The amount compounded after 16 years is $641.88. Therefore, option D is the correct answer.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$400, time period = 16 years and the rate of interest = 3%.

Here, Amount =400(1+3/100)¹⁶

= 400(1.03)¹⁶

= 400×1.605

= $641.88

Therefore, option D is the correct answer.

y = x + 1,If you know the value of x, you can solve for y by plugging the value of x into the equation and then solving for y. if x = 4,y = 4 + 1y = 5.

The equation is a mathematical expression that consists of symbols and numbers, and is used to calculate a numerical value or result. The symbols in the equation represent variables or constants, which are either given values or unknowns that need to be solved. An equation can also be used to describe relationships between different concepts, such as physical laws or chemical reactions.

y = 2x - 5

To solve for y, rearrange the equation to isolate y on one side. Subtract 2x from both sides to isolate y on the left side:

y - 2x = -5

Now add 2x to both sides to get y by itself on the left side:

y = 2x - 5

The measure of arc KT be 49 and the measure of arc LN be 17 then the measure of ∠M be 30°.

Simply put, the arc measure is the diameter of the arc relative to the circle. Since they both describe the same thing, it is literally the same as the central angle. The arc length is what you were presumably thinking about because it refers to both the length and the distance of the arc.

Divide the arc length by the circle's circumference, then multiply the result by 360 degrees to find the angle's measurement.

Any straight line connecting two places is considered an arc in general. The arc length is the measurement of an arc's length. An ordered pair of adjacent vertices is referred to as a graph arc in a graph. Any section of the circle's circumference (other than the complete curve) is referred to as an arc.

Let the measure of arc KT = 49 and the measure of arc LN = 17

If the distance to a star was suddenly cut in half, it would appear four times brighter.

The brightness of a star is directly proportional to the inverse square of its distance from us. This means that if the distance to a star is halved, its brightness will increase by a factor of four.

The relationship between brightness and distance can be expressed as follows:

B = k / d^2

where B is the brightness, k is a constant of proportionality, and d is the distance.

If the distance to the star is halved, it can be expressed as:

d' = d / 2

Plugging this into the equation for brightness, we get:

B' = k / (d / 2)^2

Expanding this and simplifying, we get:

B' = 4 * k / d^2

Since k is a constant, it cancels out and we are left with:

B' = 4 * B

This means that if the distance to a star was suddenly cut in half, it would appear four times brighter. In astronomical terms, this is equivalent to an increase of 2 magnitudes on the logarithmic magnitude scale.

The linear equation of f(n) would be -3/2 n + 4.

What is linear function f(n) ?

A linear function is one with the equation f(x) = ax + b, where a and b are real values. The gradient of the line is represented by a, while the y-axis intercept is represented by b. (which is sometimes called the vertical intercept).

A linear equation can be represented as f(n) = mn + b, where m is the slope and b is the y-intercept.

To find m and b, we can use two points from the table.

Let's use the points (6, -1) and (4, 2).

The slope, m, can be found using the formula:

m = (f(n2) - f(n1)) / (n2 - n1)

Plugging in the values from the points, we get:

m = (2 - (-1)) / (4 - 6)

m = 3 / (-2)

m = -3/2

Now that we have m, we can use one of the points and the slope to find b. Let's use the point (6, -1).

f(n) = mn + b

-1 = (-3/2)(6) + b

Solving for b, we get:

b = -1 + (3)(3) = 4

So the linear equation of f(n) is:

f(n) = -3/2 n + 4

Thus, The linear equation of f(n) would be -3/2 n + 4.

The probability of rain in a place during a long weekend (Friday, Saturday, and Sunday) is 65% . The risk of rain is between 10% and 30% on all three days.

a) The risk of rain in the destination throughout the long weekend may be calculated by adding the chance of rain on each day, which is 10% + 25% + 30% = 65%. As a result, the probability of rain at the destination throughout the long weekend is 65%.

b) The notion of conditional probability may be used to calculate the likelihood that it will rain in the destination on all three days of the long weekend. It is the likelihood of rain on Sunday given that it has already rained on:

Friday and Saturday × (the probability of rain on Saturday given that it has already rained on Friday) × (probability of rain on Friday) ×( the probability of rain on Friday).

The best lower bound for this probability is the 10% chance of rain on any given day, and the best upper bound is the 30% chance of rain on any given day.

As a result, the likelihood of rain at the destination on all three days of the long weekend is between 10% and 30%.

Using right triangle properties, The length of the guy wire, to the nearest foot is 11√(37) ft.

A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Here, 2 right triangles are formed. One between stake and pole and second between stake and cell tower.

The height of pole = 12 ft.

The distance between stake and pole = 2 ft.

The distance between pole and tower = 9 ft. so the The distance between stake and tower = 2 + 9 = 11 ft.

Let x is the angle between wire and ground.

from first right angled triangle,

tan x = 12/2

tan x = 6

from second right angled triangle

tan x = height of tower/(11)

6 = height of tower/11

height of tower = 66 ft

So, length of wire = √(66² + 11²)

⇒ length of wire = √[(11*6)² + 11²]

⇒ length of wire = √[11²(6²+1)]

⇒ length of wire = √[11²(36+1)]
