Answer:

A

Step-by-step explanation:

Answer: 16 guests

144-44=100. 144/36=4 tarts a guests. +1=5 tarts a guests. 100/5=20.

16 guests were absent to the party.

Given that Peter ordered 12 boxes of egg tarts.

Each box contains 12 tarts, so initially, there were a total of 12 * 12 = 144 tarts.

There were 36 guests invited for the party.

Each guest was supposed to receive an equal share, which would be 144 tarts / 36 guests = 4 tarts per guest.

There were 44 egg tarts left after the party.

The guests who attended ate one more egg tart than originally planned.

So, for the guests who attended, they ate 4 + 1 = 5 tarts each.

To determine the number of guests who attended, we can divide the total number of tarts eaten by the number of tarts per guest:

Total tarts eaten = 144 tarts - 44 tarts

= 100 tarts

Number of guests who attended = 100 tarts / 5 tarts per guest = 20 guests.

Since there were originally 36 guests invited, and 20 guests attended, the number of guests who were absent would be 36 guests - 20 guests = 16 guests.

Step-by-step explanation:

Answer:

0.12

Step-by-step explanation:

6 times 2 = 12

12/100 = 0.12

The solution is Option A

The relative frequency of the left handed people in the group is given by the equation A = 0.12

What is relative frequency?

A relative frequency is the ratio (fraction or proportion) of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes.

The relative frequency formula is given as:

Relative Frequency = Subgroup frequency / Total frequency

Given data ,

Let the relative frequency of the left handed people be A

Now , the equation will be

The total number of people = 50 people

The number of people in the group who were left handed = 6 people

So ,

The relative frequency of the people who were left handed A = number of people in the group who were left handed / total number of people

Substituting the values in the equation , we get

Relative frequency of the left handed people A = 6 / 50

Relative frequency of the left handed people A = 0.12

Therefore , the value of A is 0.12

Hence , the relative frequency is 0.12

The area covered by the signal is 181.37 m²

Here we can see that the area covered by the signal is the fourth of a circle of radius R = 15.2m

The area of a circle of radius R is given by:

A = 3.14*R²

Then the area of a fourth of a circle is:

A = (3.14/4)*R²

Replacing the value of the radius in the formula we will get:

A =  (3.14/4)*(15.2m)² = 181.37 m²

Answer:

its just a rotation. its as simple as rotating it back to its origonal form and matching up the corners

Step-by-step explanation:

The number of 2 points and 5 points are 30 and 8 respectively.

Let the number of 5 points = x

Let the number of 2 points = x + 22

It was also stated that the test is worth 100 points and that each problem is worth either 2 points or 5 points.

This will be:

5x + 2(x + 22) = 100

5x + 2x + 44 = 100

7x + 44 =

Collect like terms

7x = 100 - 44

7x = 56

Divide

x 56 / 7

x = 8

Number of 5 points = 8

Number of 2 points = x + 22 = 8 + 22 = 30

Answer:9/41

SOH = opposite over hypotenuse

Step-by-step explanation:

The amount of radioactive after 10 days with the same rate of change of decay will be 16.67 g.

The rate of change is the change of a quantity over 1 unit of another quantity.

Most of the time the rate of change is the change with respect to time.

For example the speed 3meter/second.

As per the given,

Radioactive decays by 1/2 of its original in 30 days.

1/2 of original → 30 days.

Divide both sides by 3

1/6 of original → 10 days

Therefore, in 10 days amount of decays will be,

1/6 of 20 ⇒ 20/6 = 3.33

The amount left = 20 - 3.33 = 16.67.

Hence "The amount of radioactive after 10 days with the same rate of change of decay will be 16.67 g".

Hi there!

The quadratic formula: \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\) where the given quadratic is in the form \(ax^2+bx+c=0\)

From the given equation \(4x^2-x-5 = 0\), we can identify the values of a, b, and c:

a=4

b=-1

c=-5

Plug these values into the quadratic formula:

\(x=\frac{-(-1)\pm\sqrt{(-1)^2-4(4)(-5)}}{2(4)}\\x=\frac{1\pm\sqrt{81}}{8}\)

\(x=\frac{1\pm9}{8}\)

\(x=\frac{1+9}{8}= \frac{5}{4} \\x=\frac{1-9}{8} = -1\)

Therefore, the solutions to the quadratic are 5/4 or 1.

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

The area of the circle with the given radius is 201.088 square units.

The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.

Given that, the radius of a circle is 8 units.

Here, area of a circle

= 3.142×8²

= 3.142×64

= 201.088 square units

Therefore, the area of the circle is 201.088 square units.
