Harold had 1,400 stamps. He gave 350 of them to his brother and the rest to his sister. What percent did he give to his brother?

Answers

Answer 1

Answer:

25%

Step-by-step explanation:

350/1400 as a simplified fraction is 1/4 because you can divide 350 into 1400.

And now we know that 1/4 is 25%.

Or just divide 1 by 4. And you'll get .25 and then just move the decimal to the right 2 times.

Hope this helps!

Answer 2

Harold gave 1,400 stamps to his brother and sister. He gave 350 stamps to his brother. What percent of stamps did Harold give to his brother.

The percent[tex]\frac{350}{1,400}[/tex] represents the number of stamps that Harold gave to his brother out of all the stamps.

To find what percent of stamps that Harold gave to his brother, we can change the fraction [tex]\frac{350}{1,400}[/tex] to a percent.

We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 350 and 1400 using 350.

350 ÷ 350 = 1

1400 ÷ 350 = 4

Our reduced fraction is [tex]\frac{1}{4}[/tex].

1 ÷ 4 = 0.25

0.25 × 100 = 25%

Therefore, Harold gave his brother 25% of his stamps.

Answer:

26.6 m

Step-by-step explanation:

Given the figures are similar

linear ratio = a : b

area ratio = a² : b²

here

area ratio = 16 : 25, then

linear ratio = 4 : 5 ( square root of both area ratio parts )

let the perimeter of the larger figure be x, then by proportion

[tex]\frac{4}{21.3}[/tex] = [tex]\frac{5}{x}[/tex] ( cross- multiply )

4x = 106.5 ( divide both sides by 4 )

x ≈ 26.6

Hence perimeter of larger figure is approximately 26.6 m

The graph of a system of two linear equations has no solution. What is true about the lines? A. The lines are perpendicular. B. The lines have the same slope, but different intercepts. C. The lines have the same intercept, but different slopes. D. The lines are on top of each other.

Answers

Answer:

B. The lines have the same slope, but different intercepts.

Step-by-step explanation:

The solution of a system of linear equations doesn't exist if the lines do not intersect each other at any point. So if there is no solution that means the lines of both equations will not intersect.

Lets look at the options one by one.

For option A:

If the lines are perpendicular, they might intersect at any point so this is not the correct option.

For Option B:

If the lines have same slop and different intercepts that means the lines are parallel. We know that parallel lines never cross each other so option B is the correct answer.

For Option C:

The lines with same intercept and different might also intersect so option C is not correct.

For Option D:

The lines being on top of each other means that the lines intersect on all points. So option D is also not correct.

The sums that appear when two fair? four-sided dice? (tetrahedrons) with sides 1?, 2?, 3?, and 4 are tossed

Answers

Final answer:

When two four-sided dice are tossed, the combined outcome ranges from 2 to 8. The probability for each outcome can be calculated by counting the number of combinations that sum to that outcome and dividing by the total number of possible outcomes (16). For example, there's one way to get a sum of 2 (1+1), so the probability is 1/16.

Explanation:

The subject of this question is probability, particularly, the sums of outcomes when tossing two fair four-sided dice (or tetrahedrons). Each dice has sides 1, 2, 3, and 4. When these dice are tossed together, the combined outcome is anywhere between the minimum value 2 (1 from each dice) to the maximum value 8 (4 from each dice).

The probability of each combined outcome can be calculated based on the total possible different outcomes (4 outcomes from each die, 4 * 4 = 16 total possibilities). To determine the probability for each combined outcome, we'd need to count the number of ways to get that particular sum:

To get a sum of 2 or 8, there's only one possible way (1+1 or 4+4), so the probability is 1/16 To get a sum of 3 or 7, there are two combinations (1+2, 2+1 or 3+4, 4+3), so the probability is 2/16 = 1/8 Similarly for other sums, count the combinations and divide by 16

A 20m ladder and a 15m ladder were leaned against a building. The bottom of the longer ladder was 7m farther from the building than the bottom of the shorter ladder, but both ladders reached the same distance up the building. Find this distance.

6m

12m

10m

9m

Answers

Answer:

The correct answer is: d=9m

Step-by-step explanation:

Ok, the ladders leaned against a building make two right triangles with same the same height, which we will call h. For the 20m ladder, its leg is (7+d) and for the 15m ladder, its leg is d, and the two hypotenuses are 20 and 15 respectively.

Then, using the Pythagorean Theorem we have:  

20m ladder:

20^2 = h^2 + (d+7)^2    (Eq. 1)

400 = h^2 + d^2 + 2*7*d + 7^2  (expanding the theorem)

400 = (h^2 + d^2) + 14*d + 49   (Eq. 2)

15m ladder:

 15^2 = h^2 + (d)^2         (Eq. 3)

Since h^2 + (d)^2 is equal to 15^2, we can substitute (2) into (3):

400 = (15^2) + 14*d + 49

400 = 225 + 14*d + 49

14*d = 400 - 225 - 49  (clearing the variable d)

14*d = 126

d = 9 m

And since we now know that d is equal to 9m. For the longer ladder is (d+7)=(9+7)=16m.

And, then the shorter ladder is 9m from the building and the longer ladder is 16m from the building

Answer:

Option C.(–∞, 2] ∪ (8, ∞)

Step-by-step explanation:

we know that

The solution of the inequality [tex]x > 8[/tex] Is the interval (8,∞)

The solution of the inequality [tex]x\leq 2[/tex] Is the interval (-∞,2]

therefore

The solution of  [tex]x > 8[/tex] or [tex]x\leq 2[/tex] is equal to

(-∞,2] U (8,∞)

Final answer:

The correct interval notation for the inequality x > 8 or x ≤ 2 is (−∞, 2] ∪ (8, ∞), which represents all numbers less than or equal to 2 and all numbers greater than 8.

Explanation:

The question asks to describe the set of numbers using interval notation for the inequality x > 8 or x ≤ 2. Interval notation is a concise way of writing sets of numbers, using brackets to include endpoints and parentheses for exclusive limits. For an inequality like x > 8, we use the notation (8, ∞) to indicate all numbers greater than 8 but not including 8 itself. Likewise, for x ≤ 2, the interval notation is [−∞, 2] which includes all numbers less than or equal to 2. When we combine these with the union because of the 'or' condition, the correct interval notation is (−∞, 2] ∪ (8, ∞). Therefore, the correct answer is C. (8, ∞) indicates all the numbers larger than 8, and (−∞, 2] includes all the numbers up to and including 2.

A set of data items is normally distributed with a mean of 500. Find the data item in this distribution that corresponds to the given z-score. z = 2, if the standard deviation is 40.

Answers

In a data set with a mean of 500 and standard deviation of 40, the data item that corresponds to the z-score of 2 is 580. This is computed by multiplying the standard deviation by the z-score and adding the product to the mean.

Explanation:

This question is dealing with z-scores and the standard normal distribution in statistics. The z-score is a measure of how many standard deviations an element is from the mean. In a standard normal distribution, the mean is 0 and the standard deviation is 1.

When you are given a z-score of 2 for a data set with a mean of 500 and a standard deviation of 40, it means the data item you're looking for is 2 standard deviations above the mean. You compute this by multiplying the z-score by the standard deviation and adding the product to the mean. So in this case, 500 + 2*40 = 580.

The absolute value is considered the distance to 0... so if there's a negative sign in the value, the negative sign disappears.

2.  All real numbers :  b.  3x = 3x

If we divide both sides by 3, we have x = x, which will always be true.

3.  x = -5  : c.  5x = -25

If we multiply each side by 5, we have 5(x) = 5(-5) thus 5x = -25

4.  No solution : a.  |2x| = -10

The result of an absolute value cannot be a negative number.  So, that has no solution since there's no value of x that would make this true.

5.  Adding the opposite to both sides of the equation. : e.  Canceling

If you have for example (x = -5) and you add 5 on both sides, you cancel the value on the right side... (becomes x + 5 = 0).

Explanation:

Finding the Standard Form Equation of a Hyperbola

The student has asked for the standard form of a hyperbola given certain characteristics such as vertices and asymptotes.

The vertices at (0, ±4) indicate that this is a hyperbola centered at the origin with its major axis along the y-axis, while the asymptotes given by y = ±2/3x help determine the relationship between the semi-major axis a and semi-minor axis b.

General Structure of a Hyperbola

For a hyperbola centered at the origin with a vertical transverse axis, the standard form is:

[tex]\(rac{y^2}{a^2} - \frac{x^2}{b^2} = 1\)[/tex]

Given that the asymptotes have slopes of ±2/3, the relationship between a and b is b/a = 2/3. Since the vertices are at (0, ±4), a = 4. Solving for b gives us b = (2/3) × 4 = 8/3.

Standard Form Equation

The standard form equation of the hyperbola is therefore:

[tex]\(rac{y^2}{16} - \frac{x^2}{(8/3)^2} = 1\)Or simplified:\(rac{y^2}{16} - \frac{9x^2}{64} = 1\)[/tex]

Answers

Final answer:

The equation 4x + 3 = 7 is solved algebraically by subtracting 3 from both sides and then dividing by 4 to find x = 1. There is no need for logarithms or the change of base formula to solve this linear equation.

Explanation:

The equation 4x + 3 = 7 is a linear equation and can be solved using simple algebraic manipulations rather than the change of base formula for logarithms. However, to show how logarithms could hypothetically be used (even though it's over-complicating this particular problem), we can take the following steps:

Divide both sides by 4: x = 1.

Therefore, the solution to the equation is x = 1. There is no need to round to the nearest thousandth as the solution is a whole number. The change of base formula, logb y = (log y) / (log b), is not necessary for this equation.

The solution to the equation [tex]\(4x + 3 = 7\) is \(x = 1\),[/tex] obtained by isolating [tex]\(x\)[/tex]

Step-by-Step Solution:

1. Write down the equation:

[tex]\[ 4x + 3 = 7 \][/tex]

2. Isolate the term with the variable [tex]\(x\):[/tex]

  - To do this, we need to remove the constant term on the left side by subtracting 3 from both sides of the equation.

[tex]\[ 4x + 3 - 3 = 7 - 3 \][/tex]

  - Simplify both sides:

[tex]\[ 4x = 4 \][/tex]

3. Solve for [tex]\(x\):[/tex]

  - To isolate [tex]\(x\)[/tex], divide both sides of the equation by 4:

Suppose the probability that the Seahawks will defeat the Raiders is 0.55. What is the complement and what does it mean?

20/9 ; the probability that the Seahawks will not defeat the Raiders.

20/9 ; the probability that the Seahawks will defeat the Raiders.

11/20 ; the probability that the Seahawks will defeat the Raiders.

0.45 ; the probability that the Seahawks will not defeat the Raiders.

Answers

Answer:

D: 0.45 ; the probability that the Seahawks will not defeat the Raiders.

Step-by-step explanation:

The complement of an event A is the set of all outcomes in the sample space that are not included in the outcomes of event A.

The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1, or for the event [tex]A[/tex], and its complement event [tex]\overline{A}[/tex] always

[tex]Pr(A)+Pr(\overline{A})=1.[/tex]

If [tex]Pr(A)=0.55,[/tex] then

[tex]0.55+Pr(\overline{A})=1\\ \\Pr(\overline{A})=1-0.55=0.45.[/tex]

Event [tex]A[/tex] - the Seahawks will defeat the Raiders

Event [tex]\overline{A}[/tex] - the Seahawks will not defeat the Raiders

Hence, correct choice is D: 0.45 ; the probability that the Seahawks will not defeat the Raiders.

Final answer:

The complement of the probability of the Seahawks defeating the Raiders is 0.45, this represents the probability of the Seahawks not defeating the Raiders.

Explanation:

In probability theory, a complement refers to the opposite event of whatever has been defined. If the probability of a certain event, in this case the 'Seahawks defeating the Raiders', is given as 0.55, then the complement of that event, 'the Seahawks not defeating the Raiders', is calculated by subtracting the given probability from 1. Hence, the probability of the Seahawks not defeating the Raiders is 1 - 0.55, which equals 0.45.

Thus, the correct answer is '0.45; the probability that the Seahawks will not defeat the Raiders'.

For the function defined by y = 1/x4, y varies inversely as what quantity

Answers

ANSWER

y varies inversely as x exponent 4.

EXPLANATION

The inverse variation equation is given as:

[tex]y = \frac{1}{ {x}^{4} } [/tex]

We can see that there is an inverse relation between the quantity y and x.

If the it were [tex]y = \frac{1}{ {x}^2 } [/tex], we say y varies inversely as the square of x.

Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.

B. Find the radius.if your answer is not an integer express it in a radical form.
C.write and equation for the circle
GIVING BRAINLIEST

Answers

Answer:

Step-by-step explanation:

A]

The center is the average values of the 2 endpoints (which is also the diameter).

x:(-10 + 4)/2 = -6/2 = -3

y:(-2 + 6)/2 = 4/2 = 2

Center(-3,2)

B]

The radius is the distance from the center to one of the end points.

r^2 = (-3 - 4)^2 + (2 - 6)^2

r^2 = (-7)^2 + (-4)^2

r^2 = 49 + 16

r^2 = 65

r = sqrt(65)

C]

(x + 3)^2 + (y - 2)^2 = 65

Graph

The graph has been included so that you can see that the center I have calculated is between (-10,-2) and (4,6)

Further, it shows the the circle goes the two end points of the diameter.

Critical development efforts cannot succeed without a legitimate and democratically elected government that is responsive and accountable to its citizens. Elections provide an important opportunity to advance democratization and encourage political liberalization. For an election to be free and fair, certain civil liberties, such as the freedoms of speech, association and assembly, are required. Elections can be a primary tool to foster political openings and expand political participation. Electoral processes offer political parties and civic groups an opportunity to mobilize and organize supporters and share alternative platforms with the public. Elections also serve to encourage political debate and public dialogue. "Supporting Free and Fair Elections," US Agency for International Development What is the main idea of this passage? 1.
