a line segment 42 inches long is divided into 3 portions in a ration of 1;2;4. how many inches longer is the longest portion than the shortest protion

Answers

Answer 1

The longest portion is 18 inches longer than the shortest portion.

What is algebraic equation ?

An algebraic equation is a mathematical statement that shows that two expressions are equal. It typically consists of a combination of numbers, variables and mathematical operations such as addition, subtraction, multiplication, and division.

We know that the ratio of the portions is 1:2:4, so we can use this ratio to find the length of each portion by dividing 42 inches by the sum of the ratio, 1+2+4 = 7.

So each portion is 42 inches / 7 = 6 inches.

The longest portion is 4 times the length of the shortest portion, which is 6 inches. So the longest portion is 4 * 6 inches = 24 inches.

24 - 6 = 18 inches ,

Therefore, the longest portion is 18 inches longer than the shortest portion.

Identify the true statements about the correlation coefficient, ????. if two variables are negatively correlated, when one variable increases, the other variable also increases. the correlation coefficient is not affected by outliers. a correlation coefficient of zero means that no relationship exists between the two variables. the sign of ???? describes the direction of the association between two variables. when the data points in a scatter plot are randomly scattered, the correlation between the two variables is weak. the value of ???? ranges from negative one to positive one.

Answers

a. Since both a strong-positive and weak-positive correlation are formally considered to be "growing," this is ambiguous (positive slope). In the same way, negative correlation. Speaking strictly in terms of truth or untrue, I would classify this as false

b. This is once more a little tricky. When "r" is zero, there isn't any evidence of a linear link. It doesn't necessarily follow that the variables don't correlate with one another. The answer is probably True if this is a course on statistics for beginners. If not, False.

c. This is simple to understand. Inverse relationships are indicated by negative coefficients. One grows while the other shrinks (or vice versa). False.

d. The range of the coefficient r is [0, 1] (inclusive), not (0,1). In this case, True if the text suggests [0,1].

e. Simple and accurate

How to use laws of exponents?

Some of the laws of exponents states that;

1) When we multiply like bases, we must keep the base the same and add the exponents.

2) When we raise a base with a power to another power, we must keep the base the same and multiply the exponents.

3) When dividing like bases, we must keep the base the same and subtract the denominator exponent from the numerator exponent.

A) [(2 * 3⁻²)³(5 * 3²)²]/(3⁻²)(5 * 2)²

Applying laws of exponents, we have;

[(2² * 3⁻²*³)(5² * 3²*²)]/(3⁻²)(5² * 2²)

= 2² and 5² will cancel out to give;

What is Law of Sines

A fundamental conclusion of trigonometry that connects a triangle's sides and angles is known as the law of sines. It claims that the following relationship holds for any triangle with sides a, b, and c and opposite angles a, b, and c:

a / sin A = b / sin B = c / sin C

In other words, each of the triangle's three sides has a length that is equal to the sine of the angle opposite it. Any triangle, correct or not, can be related to another triangle in this way.

When some of the information is available, it is common to utilize the Law of Sines to find the triangle's unknown side lengths or angle measurements. In addition to the Law of Cosines, it can also be employed alone.

Using sum of angle of triangle;

V + U + T = 180

v + 100 + 36 = 180

v + 136 = 180

v = 180 - 136

v = 44°

Answers

Answer: 176 BLUE marbles

Explanation:

First --> Total marbles ==> 264 / 0.60 = 440

Second --> Hence, the total number of BLUE marbles is 440 - 264 = 176

and there is 176 BLUE marbles

Answer:

660

Step-by-step explanation:

first, 264 yellow marbles.

the percentage of yellow is 60.

If total percentage is 100 then, blue is 100-(yellow percentage)

that is: 40 percent

the next sentence.

total marbles of blue is:

40x/100 = 264.

y/2 = (x - 5)².

Solving for 'x'.

[tex]x - 5 = \pm\sqrt\frac{y}{2}[/tex].

Answers

if the density of the metal cube is 2.3 x 10⁻³ kilograms/micro liters, 2968 cm. is the length of one side of a cube if the mass is 88 milligrams

What is significant figure?

The amount of digits that contribute to the correctness of a value—often a measurement—are known as significant figures. The first digit that is non-zero is where we begin counting significant figures.

The number of significant single digits (0 through 9 inclusive) in an expression's coefficient is referred to as the significant figures in scientific notation. The amount of accuracy or assurance an expert or scientist uses to state a quantity is indicated by the number of significant figures in a statement.

The given mass of the metal cube is 2.3 × 10⁻³kg/micro-liters or 2300000 gm/liter

The density of the metal cube is 88 mg or 0.088 gm.

Now, we know that density, d = mass/volume.

So, volume of the metal cube,

V = mass/density

V = (2300000/0.088)

V = 26136363.7 L

Now, we know that volume of a cube is a³ where a is the length of a side of the cube. So, a³ = 26136363.7 L or 26136363.7 dm³.

So, a = 296.8 dm or 2968 cm.

So, the length of one side of the cube is 2968 cm.

What is a triangle?

A triangle is a polygon with 3 sides.

Given that, the measures of the two angles of a triangle are 50° and 85°.

Let the measure of the third angle be x.

Since the sum of the interior of a triangle is 180°, it follows,

50°+85°+x=180°

135° +x = 180°

x = 180° - 135°

x = 45°

Hence, the measure of the third angle of the triangle is 45°.

The point of intersection of  r = 1 + cos(θ) and  r = 3 cos(θ)

1 + cos(θ)  = 3 cos(θ)

1 = 2 cos(θ)

=> cos(θ) = 1/2

So, two curves intersect at θ = ± [tex]\frac{\pi }{3}[/tex]

[tex]A_2 = \frac{9}{4}[0+\frac{\pi }{2} -\frac{\sqrt{3} }{4} -\frac{\pi }{3} ][/tex]

[tex]A_2= \frac{3\pi }{8}-\frac{9\sqrt{3} }{16}[/tex]

Let's Scream for Ice Cream serves 333 scoops of ice cream in its signature cone. Each scoop is a sphere with a radius of 444 centimeters. To the nearest cubic centimeter, what is the total volume of ice cream served per cone

Answers

Volume of the sphere to the nearest cubic cm will be 803.84 cm^3

A sphere has a spherical, symmetrical form. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.

The collection of all points in three-dimensional Euclidean space that are separated by a certain amount of space, or "radius," is known as a sphere (the "center"). The diameter is equal to twice the radius, and antipodes are pairs of locations on the sphere that are on opposing sides of a diameter.

Volume of sphere[tex]=\frac{4}{3} \pi r^3[/tex]

As we have the value of radius = r=4 cm

We have the value of total scoops = 3 mm

So, by putting the value in the above expression of the volume of the sphere, we will get it as:

[tex]V =\frac{4}{3} \times 3.14(4)^3 \times 3 \\=3.14 \times 256 \\=803.84 \mathrm{~cm}^3[/tex]

2(y+a)/a(x-3)

find the restriction

Answers

Answer:

  a ≠ 0

Step-by-step explanation:

You want to know the restriction applicable to 2(y+a)/a(x-3).

Undefined

A rational expression is undefined when its denominator is zero. The restrictions are applied so that no denominator is zero.

Here, the expression is ...

  [tex]\dfrac{2(y+a)}{a}(x-3)[/tex]

The only denominator is 'a'. It cannot be zero.

The restriction is a ≠ 0.

__

Additional comment

If we assume this is a relation in which x- and y- are the only variables, there is no restriction on the relation as written.

Perhaps you intend that (x-3) be a denominator factor. Then the relation would have the restriction x≠3. Such an expression would need to be written as ...

  2(y+a)/(a(x-3)) . . . . . . using parentheses around the denominator

This was a political protest by Boston in 1773 against the British parliament led by the Sons of Liberty. Battles between France and England in the new world resulting in the loss of all French possessions. This group of Patriots was formed in 1765 and urged colonial resistance to the Stamp Act using any means available... even violence. A common complaint of American Colonists, they felt they were taxed from England without having any vote in Parliament. This was an Act passed in 1765 by the British, requiring all legal documents to carry a tax mark to help pay for the military presence in the colonies. These were series of laws passed by Parliament in 1774 after the Boston Tea Party.
