which of the statements using operations on rational or irrational numbers always results in a rational number?

a) irrarional + irrational
b) irrational ÷ irrational
c) rational + irrational
d) rational ÷ rational​

Answer:

12

Step-by-step explanation:

The lowest value is indicated by the dot at the end of the left whisker

That is the lowest value = 12

The lowest value in a box-and-whisker plot is the minimum of the dataset. For the given data set, the lowest value, which is the minimum, is 10.

The student is asking us to find the lowest value represented in a box-and-whisker plot. A box-and-whisker plot is a graphical representation of a five-number summary of a dataset: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and the maximum. The lowest value in a box-and-whisker plot is the minimum of the dataset.

To graph a box-and-whisker plot for the given data values, you would first need to arrange the data in ascending order. Then, find the minimum, Q1, median, Q3, and the maximum. The smallest number, which is placed at the leftmost part of the plot, is the minimum, also known as the lowest value of the dataset. For the data set provided (10, 10, 10, 15, 35, 75, 90, 95, 100, 175, 420, 490, 515, 515, 790), the lowest value is 10.

For google to 25 shares google will have to buy 25 shares $143.00

Answer:

Step-by-step explanation:

The dividend refers to the percentage of a company's annual dividend compared to its share price.

In this case, according to the given table, we have a dividend of 5.72, which means that's the factor that tell us how much are we going to receive.

[tex]5.72 \times 25 = 143[/tex]

Therefore, we are gonna receive $143 due to the 25 shares with a dividend of 5.72.

So, the right answer is D.

Replace t with 1 through 4 and solve then add them together:

6^(1-1) = 6^0 = 1

6^(2-1) = 6^1 = 6

6^(3-1) = 6^2 = 36

6^(4-1) = 6^3 = 216

Sum = 1 + 6 + 36 +216 = 259

Answer:  The required sum is 259.

Step-by-step explanation:  We are given to find the sum of the following geometric series :

[tex]\sum_{i=1}^{4}6^{i-1}.[/tex]

The given geometric series can be written as :

[tex]0+6+6^2+6^3.[/tex]

We know that

the sum of a geometric series up to n terms with first term a and common ration r is given by

[tex]S=\dfrac{a(r^n-1)}{r-1}.[/tex]

in the given series, we have

[tex]a=1,~~r=\dfrac{6}{1}=\dfrac{6^2}{6}=\dfrac{6^3}{6^2}=6.[/tex]

Therefore, the sum up to 4 terms will be

[tex]S_4=\dfrac{a(r^4-1)}{r-1}=\dfrac{1(6^4-1)}{6-1}=\dfrac{1296-1}{5}=\dfrac{1295}{5}=259.[/tex]

Thus, the required sum is 259.

I believe it is 45 studs to the end of the wall

Answer:

Step-by-step explanation:

First, convert 20 yds to 60 ft. and then from 60 ft to 720 in.

Use the formula for the nth term of an arithmetic sequence:

l = a + (n-1)d:

Here l = 720 ft, and a = 0.  The common difference, d, is 16 in.  Our task is to determine how many studs are needed.

Substituting the knowns, we get 720 = 0 + (n - 1)(16), which simplifies to:

720 = (n-1)(16).

Divide both sides by 16 to isolate (n-1):  45 = n - 1.

Adding 1 to both sides results in 46 = n.

46 studs total are needed; if the worker has already placed the first stud, then 45 additional studs are needed.

14/125 = 0.112

125(0.112) = 14

Answer:

B. 125P=14 is the Answer

Step-by-step explanation:

1) When it says what percent 14 is of 125( what percent of 125 gives you 14)

Algebraically It's like this

125p=14

2) just solve for p

P=14/125 ( 125 is divided on both sides)

P= 0.112

3) plug in 0.112 for P

125 x 0.112 = 14

Answer:

C. 10z(x - 2y)

Step-by-step explanation:

10xz − 20y

Factor the terms

Factors of   10xz =          2 ×      5 × x ×        z

Factors of -20yz = (-1) × 2 × 2 × 5 ×       y × z

Identify their greatest common  factor

The common factors are 2, 5, and z. The greatest common  factor is 10z.

Rewrite them with the GCF as a factor

 10xz = 10z ×      x

-20yz = 10z × (-2y)

Replace the terms in the original expression with the factored terms

10xz − 20yz = 10z(x) + 10z(-2y)

Use the distributive property to isolate the greatest common factor

10z(x) + 10z(-2y) = 10z(x - 2y)

Answer:

C. 10z(x - 2y)

Step-by-step explanation:

Answer: 50

Step-by-step explanation: First of all, you need to establish your rate of acceptance. This would be 10 out of 48 or 10/48. Next, you need to simplify this to 5/24. Okay now this is epic. Now you need to convert 5/24 to x/240. Simple. Just multiply both sides by ten in 5/24 and you get your answer of 50. Very cool.

Final answer:

Michelle can expect approximately 50 students to join her book club based on the proportion of surveyed students who expressed interest.

Explanation:

Michelle surveyed 48 students, and 10 said they would join the book club. To estimate how many out of the total 240 students might join, we use proportions. The first step is to set up a proportion with the numbers Michelle has provided and then solve for the unknown:

Number of students surveyed who would join / Total students surveyed = Expected number who would join / Total students in grade

10 / 48 = x / 240

To find x, multiply both sides by 240:

240 * (10 / 48) = x

Then solve for x:

x = 50

Thus, Michelle could expect about 50 students to join the book club.

We can convert the mixed fraction into simple fraction by following method

Multiply the whole number part by the fraction's denominator.

Add that to the numerator

Then write the result on top of the denominator.

For example  [tex]2\frac{3}{5}[/tex] can be written as [tex]\frac{13}{5}[/tex]

Answer:

n  = 30

Step-by-step explanation:

The triangles share the same angle measures, so they are similar triangles.  The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...

16 is to 20 as 24 is to n

16/20 = 24/n       now solve for n by cross multiplying

16n = 480

     n = 30      (divide both sides by 16)

We are given that the original triangle and its projection are similar. This means that the corresponding angles of the two triangles are congruent, and the ratios of their side lengths are equal.

We are also given the lengths of two sides of the original triangle: 16 cm for the base and 20 cm for the hypotenuse. We are asked to find the missing length on the projection, which corresponds to the base of the original triangle.

To solve this problem, we can set up a proportion based on the similar triangles. Let x be the missing length on the projection:

(base of original triangle) / (base of projection) = (hypotenuse of original triangle) / (hypotenuse of projection)

Substituting the known values:

Cross-multiplying:

Therefore, the missing length on the projection is 19.2 cm. However, the answer choices are all rounded to one decimal place.

Rounding 19.2 cm to one decimal place gives us 19.0 cm. Therefore, none of the provided options are correct.

Step-by-step explanation:

The area of the trapezoid is found by

A = 1/2 (b1+b2)h

b1 = 2

b2 = 4

h = 4

I found these by looking at the graph

A = 1/2(2+4) 4

A = 1/2(6*4)

A = 12 units ^2

Answer:

p = 5

Step-by-step explanation:

first you need to distibute into the parenthesis's -

4p + 25 = 6(p-3) -3(4-3p)

4p +25 = 6p -18 - 12 + 9p

4p + 25 = 15p - 30

-4p            -4p

25 = 11p - 30

+30       +30

55 = 11p

/11     /11

5 = p

hope this helps!!

4p+25=6(p-3)-3(4-3p)=5

Answer:

2727

Step-by-step explanation:

The formula for finding the volume of a cone is

1/3πr²h

The radius would be 11.5 because, radius equals the diameter divided by two.

So, first you would plug your numbers into the equation

1/3(π)(11.5)²(19.7)

*use 3.14 for pi

Then multiply.

V = 2726.9 (2727 if you round to the nearest whole number)

Answer: D. 648*π in^3

Step-by-step explanation:

The formula for the volume of a cylinder is

[tex]V=\pi *r^2*h[/tex]

V=1130.973355 in^3

or simply

V=1130.97 in^3

or

V=360*π  in^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

[tex]V=\frac{4}{3} \pi *r^3[/tex]

since you have two hemispheres, its the same thing as solving for one sphere because two halves make a whole. So, the volume of the sphere is

V= 904.7786842 in^3

or simply

V= 904.78 in^3

or

V=288 *π  in^3

Finally, you add both of the volumes together to get

V= 2035.75204 in^3

or simply

V= 2035.75 in^3

or

V= 648*π  in^3

Step-by-step explanation:

Beef = 12 * 8 (cause 25 * 8 = 200)

Beef = 96

Chicken = 8 * 8 (cause 25 * 8 = 200)

Chicken = 64

Pasta = 5 * 8 (cause 25 * 8 = 200)

Pasta = 40

Answer- C] There are 32 more students who want beef meal more than want a chicken meal

The best prediction of the meals wanted by the 200 students can be determined based on the proportions from the random survey. Option A, which states that there are 16 students who want a beef meal, is the best prediction.

The best prediction of the meals wanted by the 200 students can be determined by considering the proportions from the random survey.

Based on the survey results, the best prediction of the meals wanted by the 200 students is

96 students who want a beef meal

as mentioned in option A.

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (- 4, 8)

m = [tex]\frac{8-6}{-4-4}[/tex] = [tex]\frac{2}{-8}[/tex] = - [tex]\frac{1}{4}[/tex], hence

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 4, 8 ), then

8 = 1 + c ⇒ c = 8 - 1 = 7

y = - [tex]\frac{1}{4}[/tex] x + 7 ← equation of line

Answer:

1. The area of regular pentagon = 292.5 inches²

2. The area of the regular octagon = 80 cm²

3. The area of the regular hexagon = 126 feet²

Step-by-step explanation:

∵ The area of any regular polygon = 1/2 × perimeter × apothem

1. Regular pentagon

∵ Regular pentagon has 5 equal sides

∵ The perimeter of the regular pentagon = 5 × side length

∵ S = 13 inches

∴ P = 13 × 5 = 65 inches

∵ apothem = 9 inches

∴ A = 1/2 × 65 × 9 = 292.5 inches²

2. Regular octagon

∵ Regular octagon has 8 equal sides

∵ The perimeter of the regular octagon = 8 × side length

∵ S = 4 cm

∴ P = 4 × 8 = 32 cm

∵ apothem = 5 cm

∴ A = 1/2 × 32 × 5 = 80 cm²

3. Regular hexagon

∵ Regular hexagon has 6 equal sides

∵ The perimeter of the regular hexagon = 6 × side length

∵ S = 7 feet

∴ P = 7 × 6 = 42 feet

∵ apothem = 6 feet

∴ A = 1/2 × 42 × 6 = 126 feet²
