Step-by-step explanation:

Final answer:

The numbers closest to -3/4 (-0.75) and -1/2 (-0.5) on the number line are -0.65 and -0.6 (or -3/5), respectively.

Explanation:

The question involves identifying which numbers on a list are closest to -3/4 and -1/2 on the number line. To do this, we should consider converting all the fractions and decimals to a common format (decimals) to easily compare their distances to -3/4 (which is -0.75 as a decimal) and -1/2 (which is -0.5 as a decimal).

The numbers provided are:

-0.65

-1/3 (which is approximately -0.333 as a decimal)

-7/8 (which is -0.875 as a decimal)

-3/5 (which is -0.6 as a decimal)

Now, to determine which numbers are closest to -3/4 and -1/2:

For -3/4 (-0.75), the closest number is -0.65.

For -1/2 (-0.5), the closest number is -0.6 (or -3/5).

Answer:

[tex]x=\frac{7}{5}[/tex]

[tex]y=-\frac{22}{5}[/tex]

Step-by-step explanation:

Given:

The given expressions are.

[tex]6x+y=4[/tex]

[tex]x-4y=19[/tex]

We need to find x and y values.

Solution:

Equation 1⇒ [tex]6x+y=4[/tex]

Equation 2⇒ [tex]x-4y=19[/tex]

First solve the equation 1 for y.

[tex]6x+y=4[/tex]

[tex]y = 4-6x[/tex] --------(3)

Substitute [tex]y = 4-6x[/tex] in equation 2.

[tex]x-4(4-6x)=19[/tex]

Simplify.

[tex]x-(4\times 4 - 4\times 6x)=19[/tex]

[tex]x-(16-24x)=19[/tex]

[tex]x-16+24x=19[/tex]

Add 16 both side of the equation.

[tex]25x-16+16=19+16[/tex]

[tex]25x=35[/tex]

[tex]x=\frac{35}{25}[/tex]

Divide Numerator and denominator by 5.

[tex]x=\frac{7}{5}[/tex]

Substitute x value in equation 3 and simplify.

[tex]y=4-6(\frac{7}{5})[/tex]

[tex]y=4-\frac{6\times 7}{5}[/tex]

[tex]y=4-\frac{42}{5}[/tex]

[tex]y=\frac{5\times 4-42}{5}[/tex]

[tex]y=\frac{20-42}{5}[/tex]

[tex]y=-\frac{22}{5}[/tex].

Therefore, the value of [tex]x=\frac{7}{5}[/tex] and [tex]y=-\frac{22}{5}[/tex].

[tex]33\frac{1}{3}[/tex] number of messages she can send and receive so the unlimited plan is cheaper than paying for each message

Solution:

Natalie can send or receive a text message for $0.15

Natalie can get an unlimited number for $5

To find: Number of messages she can send and receive so the unlimited plan is cheaper than paying for each message

Let "x" be the number of messages

Cost for sending and receiving message = $ 0.15

Cost for unlimited plan = $ 5

Then, according to given, we frame a inequality as:

The condition is: unlimited plan is cheaper than paying for each message

Therefore,

(number of messages)(Cost for sending and receiving message) is greater than or equal to Cost for unlimited plan

[tex]x \times 0.15\geq 5\\\\0.15x\geq 5\\\\\text{Solve for "x" }\\\\\text{Divide both sides of equation by 0.15 }\\\\\frac{0.15x}{0.15}\geq \frac{5}{0.15}\\\\x\geq 33.33\\\\x\geq 33\frac{1}{3}[/tex]

Thus for [tex]33\frac{1}{3}[/tex] messages ,the unlimited plan is cheaper than paying for each message

Kramer collected = 225000

Elaine collected   = 5000

Newman collected = 45000

Solution:

Given Jerry collected 45000.

Kramer collected = 5 times more than Jerry collected

                             = 45000 × 5

                             = 225000

Kramer collected = 225000

Elaine collected   = 9 times less than Jerry collected

                             = 45000 ÷ 9

                             = 5000

Elaine collected   = 5000

Newman collected = same as Jerry collected

                                = 45000

Newman collected = 45000

The slope is 0

Step-by-step explanation:

This is a horizontal line, and all horizontal lines have a slope of 0.

(to see why, just pick any two points, and work out the change in x over the change in y. i.e. rise/run.  Since the y coordinates are all equal to 2, the numerator will be 2 -2, meaning the fraction is 0).

The slope is 0. This is because the line is horizontal. Any horizontal line has a slope of 0. Please tell me if you understand! I hope this helps!

Then:

[tex]csc A=\frac{5}{3}=1.66[/tex]

3) [tex]sec B=\frac{1}{cos B}[/tex]

[tex]frac{1}{cos B}=\frac{1}{\frac{4}{5}}[/tex]

Then:

4) [tex]tan A=\frac{opposite-side}{adjacent-side}=\frac{3}{4}[/tex]

Then:

[tex]tan A=\frac{3}{4}=0.75[/tex]

Second exercise:

5) Here, we are given another right triangle and we have to find the measure of the angle [tex]z[/tex].

So, according to the figure, we can use the tangent function:

[tex]tan z=\frac{opposite-side}{adjacent-side}[/tex]

[tex]tan z=\frac{8}{10}[/tex]

Finding the value of [tex]z[/tex]:

[tex]z=tan^{-1}\frac{8}{10}[/tex]

Answer:

the equation that contains the following 2 points is y=5x-16 which is C.

Tom and Juanita, starting from the same point and biking in opposite directions for 3 hours, will end up 162 miles apart.

Starting from the same point, Tom and Juanita go biking in opposite directions for 3 hours. From what we know, Tom rides at a speed of 24 mph and Juanita rides at a speed of 30 mph.

When an object moves in one direction, its distance travelled is calculated from the formula distance = speed x time. This is because speed is described as the distance travelled per unit time. In this case, Tom travels 24 miles in 1 hour, so in 3 hours, he will cover 24 mph x 3 hours = 72 miles. Juanita will cover 30 mph x 3 hours = 90 miles.

Because they are moving in opposite directions, these distances add together. So in 3 hours, Tom and Juanita will be 72 miles + 90 miles = 162 miles apart.

https://brainly.com/question/14362959

#SPJ12

Tom and Juanita will be 162 miles apart after 3 hours of biking in opposite directions at their respective speeds.

To solve this problem, we can use the formula for distance, which is the product of speed and time.

Since Tom and Juanita are riding in opposite directions, their distances from the starting point will add up to the total distance between them after a certain amount of time.

The correct total distance apart should be calculated as follows:

Answer:

The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.

Step-by-step explanation:

The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.

For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)

The Irrational Conjugate Theorem states that if a complex number is irrational, then its conjugate is also irrational. It is used in mathematics to prove this relationship. The theorem is based on the definition of the conjugate of a complex number, and a proof by contradiction approach can be used to prove it.

The Irrational Conjugate Theorem is used in mathematics to prove that if a complex number is irrational, then its conjugate is also irrational. This theorem is based on the concept of the rational and irrational parts of a complex number. Let's define a complex number as z = a + bi, where a and b are real numbers and i is the imaginary unit. The conjugate of z, denoted by [tex]\bar Z[/tex], is obtained by changing the sign of the imaginary part. So, if z = a + bi, then [tex]\bar Z = a - bi.[/tex] The Irrational Conjugate Theorem states that if a + bi is an irrational complex number, then a - bi (the conjugate) is also irrational.

To prove this theorem, we can use a proof by contradiction approach. Let's assume that a + bi is irrational and a - bi (the conjugate) is rational. We can then use valid reasoning to arrive at contradictory results. For example, we can add a + bi and a - bi to get 2a, which is a rational number. However, this contradicts our initial assumption that a + bi is irrational. Therefore, our assumption must have been false and the theorem is proven.

Final answer:

The correct statement is that if there is a definite pattern in the residual plot, the least squares regression line is not a good fit. It indicates that potentially another model might better capture the variability in the data. So the correct option is B.

Explanation:

The correct statement about the residual plot for a set of data with a linear regression equation is that if there is a definite pattern in the residual plot, it suggests that the least squares regression line is not a good fit for the data. A good fit would be indicated by residuals that are randomly scattered around the horizontal axis, with no apparent pattern. This is because the residuals, which represent the differences between the observed values and the values predicted by the regression line, should not correlate if the model is appropriate for the data set.

The correct option is B) The least squares regression line is not a good fit as there is a definite pattern in the residual plot. This indicates that the linear model may not be capturing all the variability in the data, and some other models might be more appropriate. Option A is incorrect because a definite pattern in the residuals is a sign of a poor fit. Options C and D are not correct because having the same number of points above and below the line does not necessarily mean the model is a good fit; it's the pattern in the points that matters.

To clear the slide that left 40,000 cubic yards of material on the road, approximately 2,666.67 dump truck loads would be needed.

In the first scenario, a landslide resulted in 3,000 cubic yards of material obstructing the highway. This volume of material requires 200 dump truck loads for removal.

By dividing the total volume (3,000 cubic yards) by the number of loads (200), we can calculate that each dump truck load can carry 15 cubic yards of material.

3,000 / 200 = 15 cubic yards of material.

Now, applying this knowledge to the second scenario, where a landslide left 40,000 cubic yards of material on the road, we can determine the number of dump truck loads needed to clear it.

By dividing the total volume of material (40,000 cubic yards) by the volume each truck load can carry (15 cubic yards), we get the number of dump truck loads required for cleanup.

=> 40,000 / 15 = 2,666.67

Answer:

The side length of the square will be 11 cm.

Step-by-step explanation:

Tessa wants to make a bandana for her dog by folding a square cloth into a 45-45-90 triangle.

Her dog's neck has a circumference of about 32 cm. the folded bandana needs to be an extra 16 cm long so Tessa can tie it around her dog's neck.

So, the hypotenuse of the 45-45-90 triangle has a length of (32 - 16) = 16 cm.

As a 45-45-90 triangle is an isosceles right triangle with side length a cm (say), then

[tex]\sqrt{a^{2} + a^{2}} = 16[/tex]

⇒ 2a² = 16² = 256

⇒ a² = 128

⇒ a = 8√2 cm.

Therefore, the side length of the square will be 8√2 cm ≈ 11 cm. (Answer)

The side length of the square should be [tex]34cm[/tex] (to the nearest cm)

After folding the square cloth into a bandana, the diagonal has to be [tex]32cm+16cm=48cm[/tex] so that it can tie around the dog's neck.

Using Pythagoras' theorem, the relationship between the sides of the square cloth and the diagonal will be

[tex]diagonal=\sqrt{side^2+side^2}\\diagonal=side\sqrt{2}[/tex]

substituting and solving for the required side length, we get

[tex]48=side\sqrt{2}\\side=24\sqrt{2}\approx 34cm[/tex]

The length of the unknown leg is approximately 35.4 inches.

The image shows a right triangle with the following dimensions:

The base of the triangle is 24 inches.

The height of the triangle is 26 inches.

We can use the Pythagorean theorem to solve for the length of the missing leg. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two legs.

Let us call the unknown side "ao".

In this case, we can write the equation as follows:

ao^2 = 24^2 + 26^2

where:

ao is the length of the hypotenuse (unknown)

24 is the length of the base

26 is the length of the height

Simplifying the equation:

ao^2 = 576 + 676

ao^2 = 1252

ao = sqrt(1252)

ao ≈ 35.4 inches

Therefore, the length of the unknown leg is approximately 35.4 inches.
