Answer: x=1/4

Step-by-step explanation:

1. You want to isolate the variable, in other words get it by itself. You do that be dividing by 8 to both sides, 8x/8 is just x and 2/8 is 1/4, so therefore x=1/4

2. you can plug in 1/4 for x to check it. 8 x 1/4 is 2, and 2=2 ✅

Answer:x=1/4 or x=0.25 I hope this helpful mark me brainlist if correct

Step-by-step explanation:

8x=2

Divide both sides of the equation by 8

8x divide 8=2 divide 8

Any expression divided by itself equals 1

x=2 divide 8

then write the the division as a fraction

X=2/8

Cancel out the common factor 2 and 8

X=1/4 or x=0.25

The volume of the liquid in the bigger flask which is in the shape of the cone is V = 980π.

A cone is a recognizable three-dimensional geometric shape with a smooth and curving surface that is directed upward in mathematics. The

Greek word "konos," which denotes a peak or a wedge, is the source of the English word "cone."

The apex is the pointy end, while the base is the level area.

So, the volume of liquid in the bigger flask:

We know that the radius of the bigger flask is 14cm.

The liquid is filled to a height of 15cm.

The volume of cone formula: V = πr²h/3

Substitute values as follows:

V = πr²h/3

V = π(14)²15/3

V = π196*5

V = 980π

Therefore, the volume of the liquid in the bigger flask which is in the shape of the cone is V = 980π.

Answer:

  40 m

Step-by-step explanation:

Given midline JK = (6x -4) m and baseline HG = 10x m, you want the measure of HG.

The midline of a triangle is half the length of the parallel baseline.

  JK = 1/2·HG

  6x -4 = 1/2(10x)

  x -4 = 0 . . . . . . . . . subtract 5x

  x = 4

  10x = 10·4 = 40

The measure of HG is 40 meters.

The equation of the line passing through the points (0, 6) and (3, 0) is y = -2x + 6.

What is the slope of the equation?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

To find the equation of the line passing through the points (0, 6) and (3, 0), we can use the two-point form:

y - y1 = m(x - x1)

where (x1, y1) is one of the given points, and m is the slope of the line.

To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates of the given points, we get:

m = (0 - 6) / (3 - 0)

= -6 / 3

= -2

Substituting this value for m and the coordinates of one of the given points into the two-point form, we get:

y - 6 = -2(x - 0)

Combining like terms and multiplying through the parentheses, we get:

y = -2x + 6

Hence, the equation of the line passing through the points (0, 6) and (3, 0) is y = -2x + 6.

Step-by-step explanation:

To find the amount of money in the account after 7 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the final amount in the account, P is the initial deposit (5300), r is the annual interest rate (7.5%), n is the number of times the interest is compounded per year (1, since the interest is compounded annually), and t is the number of years the money is invested (7).

Plugging these values into the formula, we get:

A = 5300(1 + 0.075/1)^(1*7)

= 5300(1.075)^7

= $7953.33

So, the amount of money in the account after 7 years would be $7953.33.

A counterexample is an example that proves the conjecture to be false.

Let's go through the list of values and test the claim

Is 32 divisible by 2? Yes because 16*2 = 32. Is it also divisible by 4? Yes because 8*4 = 32. So we can cross choice A off the list

Is 12 divisible by 2? Yes because 6*2 = 12. Is it also divisible by 4? Yes because 3*4 = 12. So we can cross choice B off the list.

Is 40 divisible by 2? Yes because 2*20 = 40. Is it also divisible by 4? Yes because 4*10 = 40. Choice C is also crossed off the list.

Is 18 divisible by 2? Yes because 2*9 = 18. Is it also divisible by 4? No. We can see that by dividing 18/4 = 4.5 which is not a whole number result. Or you can list out the multiples of 4 which are 4, 8, 12, 16, 20 and we see that 18 is not on the list.

Answer: 77.5% of people prefer beaches

Step-by-step explanation:

First, find the total amount of people in the survey and you get 80.

Then, also find the amount of people that prefer beaches. 62.

Then you follow this equation:

(Total # of people who prefer beaches) divided by (Total # of people in survey)

= 62/80 = 0.775

After that, you multiply 0.775 x 100 and you get your percentage :D

0.775 x 100 = 77.5% or 77%

Hope this help ^_^

Answer:

Answer:

  $13,000

Step-by-step explanation:

You want to know the class width when the class ranges are defined as ...

The class width is the difference between adjacent corresponding boundaries. These are the differences of the low boundaries.

  $48,000 -$35,000 = $13,000

  $61,000 -$48,000 = $13,000

The class width is $13,000.

__

Additional comment

Often, the class boundaries are defined to be values that cannot be part of the data set. If data is rounded to the nearest dollar, the boundaries might be defined as $34,999.50 and 47,999.50, for example. That way, it is clear that both of the values $35,000 and $47,999 will fall into the first class.

The way the classes are defined here, we have to assume that both $35,000 and $47,999 will fall into the first class. However you define the classes, the class for any given data value should never be ambiguous.

The problem with gaps, such as the gap between 47,999 and 48,000, is that you don't know how to assign an "in-between" value to a class. We have to assume here that the ambiguity is resolved by not allowing any data values in that gap.

For your test, you'll want to know how your curriculum defines class width, data or class range, and class boundary, and the procedure recommended for determining class boundaries.

The hand will cover a distance of 1055.04  inches in 7 days.

To establish the distance covered by the  hand's point would go in a week, we would first need to determine the radius of the clock's circle, for which the hand serves as a proxy .

To accomplish this, we would utilize the equation 2(pi*radius),

where pi equals 3.14.

The solution to p=2(3.14*1 ) is 6.28  inches.

This indicates that the hand's point moves 6.28inch every 1 hours.

To determine how far the hand moves in a 168 hour, we would multiply 6.28 inch by 168.

Answer:

7

Step-by-step explanation:

The gradient of a line is a measure of how steep the line is. It is calculated as the change in the y-value (the "rise") divided by the change in the x-value (the "run").

In the equation y = 7x + 8, the coefficient of x (7) is the gradient of the line. This means that for every 1 unit change in the x-value, the y-value changes by 7 units.

So the gradient of the line y = 7x + 8 is 7.

9.869604...

Step-by-step explanation:

Pie to the second power, or pi squared, is the mathematical operation of multiplying pi (3.14159...) by itself. The result of this operation is equal to 9.869604...

In mathematical notation, pi squared is written as π^2, which is the same as saying "pi to the power of 2". This means that π^2 = π * π = 9.869604...

In general, raising a number to the second power means multiplying the number by itself. For example, 2^2 = 2 * 2 = 4, and 3^2 = 3 * 3 = 9. Similarly, pi squared is just the product of pi multiplied by itself.

pi is approximately 3.14159265359

The constant of proportionality is 2.

What are direct and indirect variations ?

One quantity directly changes in response to a change in another quantity, which is referred to as direct variation. This suggests that if one quantity increases, the other will follow suit and rise in proportion. In a similar manner, if one quantity declines, the other amount also declines.

When one parameter declines while the other rises or vice versa, this is known as inverse variation. This means that the magnitude or absolute value of one item decreases as the other quantity rises, resulting in a constant value for their product. This item is also referred to as the proportionality constant.
