Find out the percentage of people who had mispriced item.

3/50 = 0.06

6% of people had mispriced items.

Find 6% of 1,350.

81

81 people would have mispriced items.

Answer:

81

Step-by-step explanation:

I did this by doing 1,350 ÷ 50, which gave me 27. I then did 27 times 3, the average amount of people with a mispriced item per 50 people, which gave me 81 as a result. And with that, I can conclude that you would expect there to be 81 people per day who have a mispriced item.

Answer:

Step-by-step explanation:

2x + 3x + 40 =180

5x= 180 - 140

5x=140

x= 28

Answer:

Step-by-step explanation:

We know that the sum of interior angles of a triangle is 180° so we can say:

40 + 2x + 3x = 180°

40 + 5x = 180°

5x = 140°

x = 28°

Now substitute in 28 for the value of x in Angle A:

=> 2x would become 2(28)

=> 56° = ∠A

Hope this helps!

Answers

Answer:

its sqrt (50)

Step-by-step explanation:

The triangle has a right angle, therefore we can use the Pythagorean theorem to find the hypotenuse. According to the theorem the sum of the squares of both other sides is equal to the square of the hypotenuse.

We have 5^2+5^2=c^2

=> 25+25=c^2

=> 50=c^2

Therefore c or the missing side is equal to sqrt(50)

Let U = {5, 10, 15, 20, 25, 30, 35, 40, 45, 50} A = {5, 10, 15, 20, 25} B = {25, 30, 35, 40, 45} C = {10, 20, 30, 40, 50} Find A∪B

Answers

Answer:

B = {25, 30, 35, 40, 45}

Find A∪B

There are 5 elements in set A

There are 5 elements in set B

A∪B is the combination of all the elements in set A and set B without repeating any

A∪B = {5, 10, 15, 20, 25, 30, 35, 40, 45}

A∪B has 9 elements in it

A ⋂ B = {25}

How many blocks with dimensions of One-third times 1 times 1 can fit in a unit cube?
A block has a length of one-third, height of 1, and width of 1.
2
3
6
9

Answers

Given:

Dimensions of a block are [tex]\dfrac{1}{3}\times 1\times 1[/tex].

To find:

The number of block that can be fit in a unit cube.

Solution:

Volume of a cuboid is:

[tex]V=l\times b\times h[/tex]

Where, l is length, b is breadth or width and h is the height of the cuboid.

So, the volume of the given block is:

[tex]V_1=\dfrac{1}{3}\times 1\times 1[/tex]

[tex]V_1=\dfrac{1}{3}[/tex]

Dimensions of a unit cube are [tex]1\times 1\times 1[/tex]. So, the volume of the unit cube is:

[tex]V_2=1\times 1\times 1[/tex]

[tex]V_2=1[/tex]

We need to divide the volume of unit cube by the volume of a block to find the number of block that can be fit in a unit cube.

So, the number of blocks that fit in a unit cube is:

[tex]n=\dfrac{V_2}{V_1}[/tex]

[tex]n=\dfrac{1}{\dfrac{1}{3}}[/tex]

[tex]n=3[/tex]

Therefore, the correct option is B.

Answer:

the answer would be "b" 3 because its in 1/3 and the block is 1/3

If £2000 was put into a bank acount that pays 3% compound intrest per year, how much will be in the account after 2 years

Answers

Answer:

After 2 years, there will be £ 2,121.80 in the account.

Step-by-step explanation:

Since £ 2000 was put into a bank account that pays 3% compound intrest per year, to determine how much will be in the account after 2 years the following calculation must be performed:

2000 x (1 + 0.03 / 1) ^ 1x2 = X

2000 x 1.03 ^ 2 = X

2,121.8 = X

Therefore, after 2 years, there will be £ 2,121.80 in the account.

Step-by-step explanation:

an object hangs from a string in a stable position and is represented by the function y=4sin(3x)+4, with time in x seconds. what is the maximum height of the object, and when does it occur on the interval 0

Answers

Answer:

Here we have the position of an object represented by the equation:

y = 4*sin(3*x) + 4

Where we can assume that y represents the height of the object.

We want to find the maximum height of the object, and for which value of x it happens in the interval 0 ≤ x ≤ 5

First let's find the maximum height.

y = 4*sin(3*x) + 4

Here the only variation is on the sin( ) part, we know that the maximum value of the sin(x) function is:

sin(x) = 1

when x = 90° = pi/2 = 3.14/2

Replacing that in the equation, we get:

y = 4*1 + 4 = 8

The maximum height of the object is 8.

Now, we know that the maximum of the sin(x) function is when x = pi/2

But in our case, we have the function sin(3*x)

Then this function is maximized when:

3*x = pi/2

x = pi/(2*3) = pi/6 = 3.14/6

And:

0 < 3.14/6 < 5

Then the first maximum occurs at x = 3.14/6 = 0.52

But it can happen again on the interval.

The next maximum of the sin(x) function is when:

x = pi/2 + 2*pi

In our case, we again have sin(3*x), then we need to solve:

3*x = pi/2 + 2*pi

x = (pi/2 + 2*pi)/3 = (3.14/2 + 2*3.14)/3 = 2.62

This is also in the interval 0 < x < 5

The next maximum of sin(x) happens at:

x = pi/2 + 2*pi + 2*pi

In our case, for sin(3*x) we need to have:

3*x = (pi/2 + 2*pi + 2*pi)

x = (3.14/2 + 2*3.14 + 2*3.14)/2 = 4.71

This again is in the interval 0 < x < 5

(is closer to the upper value, so we can expect that the next maximum does not belong to the interval)

Then the maximum height occurs at:

x = 0.52

Then occurs again at:

x = 2.62

And finally occurs again at:

x = 4.71

3) Due to rotation of earth on its axis , the stars appear to move from west to east in the sky. Actually stars don't move as they are constant in their position but they appear to move with respect to earth.

4) Both the motion of stars & motion of sun are similar because both are an example of apparent motion. Both appear to change their respective positions but in reality , sun & stars are constant in their positions. But as earth is rotating , it appears like sun & stars are changing their positions.
