what's 20 percent of 376,900​

Answer:

B

Step-by-step explanation:

The distance of a run compared with the number of times around a track.

The question asks for what is most likely to have a constant rate of change. This means that for every x, there is about the same y, as a constant rate of change means that there is a consistent slope, which is the x and y value. In real world terms, it means that you can expect every one value to change however much without changing randomly.

For example, when you buy a pizza, you expect a pizza to get you 8 slices. When you get two, you expect to get 16, 3 gets you 24 slices, and so on. This expectation is based off the constant rate of change, as you get 8 slices for each pizza. The slices would be modeled as y and the pizza would be modeled as x in mathematical terms in this situation.

Because we know that the track's distance doesnt change with every lap, we can expect it to have a constant rate of change. This concept is the same as the pizza as discussed earlier. Every lap would get her a certain amount of miles, and every other lap would increase the same amount.

Step-by-step explanation:

Head: 5/2= 2.5, 2.5 x 3.14 = 7.85, 7.85 x 7.85= 61.6225

Neck: 2 x 2 = 4

Body: 7 x 10= 70

Arms: 8 x 3 = 24, 24 + 24 = 48

Legs: 4 x 2 = 8, 8 + 8 = 16

Shoes: 4 x 3= 12, 12 + 12 + 24

Triangle: 3 x 4= 12, 12/2 = 6, 6 + 6 = 12

Total: 61.6225 + 4 = 65.6225, 65.6225 + 70 = 135.6225, 135.6225 + 48= 183.6225, 183.6225 + 16 = 199.6225, 199.6225 + 24= 213.6225, 213.6225 + 12 = 225.6225

Answer:

Step 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

n(n + 1) = 8(n + 2) + 2              ust the distributive property

n² + n = 8n + 16 + 2

n² + n = 8n + 18               subtract 8n from both sides

n² - 7n = 18          subtract 18 from both sides

n² - 7n - 18 = 0

n² - 9n + 2n - 18 = 0

n(n - 9) + 2(n - 9) = 0

(n - 9)(n + 2) = 0 ⇔ n - 9 = 0 or n + 2  =0

n - 9 = 0     add 9 to both sides

n = 9

n + 2 = 0          subtract 2 from both sides

n = -2 < 0

n + 2 = 9 + 2 = 11

Answer:

8

Step-by-step explanation:

The sum of the internal angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

Step-by-step explanation:

Answer:

D. 1/8

Step-by-step explanation:

Count the total sections - 8

Count how many 4s there are - 1

Reduce if possible, not possible here.

The probability of spinning getting 4 on the spinner will be 0.125.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The shinner has 8 equal sections.

The total number of events will be

Total event = 8 {1, 1, 1, 2, 2, 3, 3, 4}

Then the probability of spinning getting 4 on the spinner will be

Favorable event = 1 {4}

Then the probability will be

P = 1 / 8

P = 0.125

P = 12.5%

To graph y = |x+2|, consider the parent function y = |x| and translate it 2 units to the left. Choose x-values, find the corresponding y-values, and plot the points. Connect the plotted points to obtain the graph of y = |x+2|.

To graph the equation y = |x+2|, we will first consider the parent function y = |x|, which is a V-shaped graph that passes through the origin. Translating the graph y = |x| to the left by 2 units gives us y = |x+2|.

To plot the graph, we can choose various x-values and find the corresponding y-values. For example, when x = -4, y = |(-4)+2| = 2. Similarly, when x = -2, y = |(-2)+2| = 0. We can continue this process to find more points and then plot them on a coordinate plane.

By connecting the plotted points, we will obtain the graph of y = |x+2| which will be a V-shaped graph shifted 2 units to the left.

Answer:

width is 48, length is 60

Step-by-step explanation:

Answer:  The dimensions of the field are

width = 40 ft and length = 60 ft.  

Step-by-step explanation:  Given that a field with an area of 2880 ft² has the shape of a rectangle with length 12 ft larger than the width.

We are to find the dimensions of the field.

Let w ft be the width of the given rectangular field.

Then, the length of the field will be (w + 12) ft.

According to the given information, we have

[tex]w \times (w+12)=2880\\\\\Rightarrow w^2+12w=2880\\\\\Rightarrow w^2+12w-2880=0\\\\\Rightarrow w^2+60w-48w-2880=0\\\\\Rightarrow w(w+60)-48(w+60)=0\\\\\Rightarrow (w-48)(w+60)=0\\\\\Rightarrow w-48=0,~~~w+60=0\\\\\Rightarrow w=48,-60.[/tex]

Since the measure of a side of a rectangle cannot be negative, so w = 48.

This implies that

length of the field = w + 12 = 48 + 12 = 60 ft.

Thus, the dimensions of the field are

width = 40 ft and length = 60 ft.

There is

[tex]3.219\times {10}^{5} [/tex]

more money in the vault in the evening than in the morning.

EXPLANATION

The amount of money in the vault in the morning is

[tex]2.81 \times {10}^{4} [/tex]

The amount of money in the vault at the end of the day is:

[tex] 3.5 \times {10}^{5} [/tex]

To find how much more money is in the vault at the end of the day than there was in the morning, we subtract to get:

[tex]3.5 \times {10}^{5} - 2.81 \times {10}^{4} [/tex]

[tex] = 3.5 \times 100000 - 2.81 \times 10000[/tex]

[tex]350000 - 28100= 321900[/tex]

Therefore, there is

Step-by-step explanation:

Inequalities of the type | x | > a always have solutions of the form

x < - a or x > a, thus

2x + 1 < - 5 OR 2x + 1 > 5 ( subtract 1 from both sides of both inequalities

2x < - 6 OR 2x > 4 ( divide both sides of both inequalities by 2 )

x < - 3 OR x > 2

Answer:

(5x+3y) and (5x-3y)

Step-by-step explanation:

From the concept on difference between two squares;

a² - b² = (a+b)(a-b)

Therefore;

25x² - 9y² = (5x+3y) (5x-3y)

Therefore the dimensions of the square are (5x+3y) and (5x-3y)

Answer:

the dimensions of the rectangle are (5x + 3y) and (5x - 3y)

Step-by-step explanation:

The area of a rectangle is 25x^2 - 9y^2 square units.

To find the dimensions of a rectangle we need to factorize the expression completely.

We know that (a + b)(a - b) = a^2 - b^2

In this case: a^2 = 25x^2 and b^2 = 9y^2

So a = sqrt(25x^2) = 5x

And b = sqrt (9y^2) = 3y

Then the solution is:

(a + b)(a - b) = (5x + 3y)(5x - 3y)

Then the dimensions of the rectangle are (5x + 3y) and (5x - 3y)

Answer:

9 1/8

Step-by-step explanation:

1. first take away the fraction part and take the whole numbers off of the numbers and add them!

1 + 3 + 5 =  9

2. now take that aside and keep that for later... now lets focus on the

1/2, 3/4, and the 1/8 these are the STARS you will be focusing on!

3. now, find the common denominator in these fractions!!!

how? here is how!

       1. lets list these fractions:

1/2, 3/4, and 1/8

the common demoninator is 8 because 1. its one of the highest in this set and 2. if you multiply 1/2 and 3/4 n the numerator and the demoentator by 4 they can create  a 8 denminator and then you can add them!

4. Next, I wont be explaning you just watch!

3        x2             6

_     =               _                  

4          x2            8    (to get to 8 from 4 you multiply by 2! so you do the same for the upper one!!!)

1      x4          4

_     =        _

2       x4        8

you dont do anything to 1/8 because its already part of the eights family! :D

5. I know, it took us a LONG way here but here it is! the final! now, time to add them!

     4/8, 6/8 and 1/8

6. lastly...

1 1/8 + 9 = 9 1/8

Hope this helpes! sorry this was so long!!! :D

To get the answer type 2•4•3+2•4•2+2•3•2

in to a calculator And you’ll get “52m”

Answer:

52 m²

Step-by-step explanation:

The prism has 6 rectangular faces.

Opposite faces are congruent, that is

top/bottom, front/back and sides

A = 2(4 × 3) + 2(3 × 2) + 2(4 × 2)

   =( 2 × 12) + (2 × 6) + (2 × 8)

   = 24 + 12 + 16

   = 52 m²

Just divide [tex]\mathbf u[/tex] by its magnitude:

[tex]\|\mathbf u\|=\sqrt{5^2+6^2+(-1)^2}=\sqrt{62}[/tex]

So a unit vector in the direction of [tex]\mathbf u[/tex] is

[tex]\dfrac{\mathbf u}{\|\mathbf u\|}=\dfrac5{\sqrt{62}}\,\mathbf i+\dfrac6{\sqrt{62}}\,\mathbf j-\dfrac1{\sqrt{62}}\,\mathbf k[/tex]

Then multiply this by -1 to get a unit vector pointing in the opposite direction.

To find the unit vector in the direction of a vector u, divide each component by its magnitude. For a vector u=i+j, the unit vector direction is ½(i+j), and the opposite direction is ½(-i-j).

To find a unit vector in the direction of a given vector u, we must first calculate the magnitude (or length) of u and then divide each component of u by that magnitude. Let's assume the vector u has components i and j. The magnitude of u, denoted as |u|, is given by the square root of the sum of the squares of its components, which is √(i² + j²). The unit vector in the direction of u is then the vector u divided by its magnitude, Û = (i/|u|, j/|u|).

In the case of the vector u = i + j, the magnitude is √(1² + 1²) = √2, and so the unit vector in the direction of u is Û = ½(i + j). Conversely, the unit vector in the direction opposite to u would be Û = ½(-i - j) since we are simply negating each component of the unit vector in the direction of u.

The correct option is 1.

Step-by-step explanation:

It is given that the box plot shows the number of books sold each day at a store for 80 days.

A box plot is drawn with end points at 0 and 16.  It means minimum value is 0 and maximum is 16.

The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.

He have to find the number of days in which the bookstore sell 2 to 12 books.

2 is first quartile and 12 is third quartile, we know that

[tex]Q_1=25\%[/tex]

[tex]Q_3=75\%[/tex]

[tex]Q_3-Q_1=75\%-25\%=50\%[/tex]

The data lies between Q₁ and Q₃ is 50% of the data.

[tex]80\times \frac{50}{100}=40[/tex]

The bookstore sell 2 to 12 books in 40 days.

Therefore, the correct option is 1.
