Answer:
188
Step-by-step explanation:
6*6=36
(6+13=19)*8=152
152+36=188
Answer:
The area of the composite figure is 188 m^2
Step-by-step explanation:
Let's work with the square first.
Given,
Length of one side of the square = 6m
We know,
Area of square region = ( Length of one side of the square)^2 sq. unit
= [tex]6^{2}[/tex] m^2
= 36 m^2
Again,
Length of the rectangle = (13 + 6) m = 19 m
Breadth of the rectangle = 8 m
We know,
Area of the rectangular region = (Length X Breadth) sq. unit
= ( 19 X 8 ) m^2
= 152 m^2
∴ The total area = (36+152) m^2
= 188 m^2
So, the area of the composite figure is 188 m^2.
Si el diametro de la Tierra es de 12 756 kilometros , ¿Qué tienes que hacer para saber cuál es la medida de su circunferencia
Answer:
40079 Km
Step-by-step explanation:
La circunferencia de la tierra está dada por;
C = 2πR
Dónde;
R = radio de la tierra
Tenga en cuenta que;
R = D / 2
Por eso;
C = 2πD / 2
C = πD
C = 3.412 * 12756 kilómetros
C = 40079 Km

Ahmad and 19 of his friends won a competition.they shared the prize money of $70,000 equally.ahmad saved $2500 of his share and donated the rest.How much did ahmad donate?
==========================================================
Explanation:
There are 1+19 = 20 people total. The prize money $70,000 is divided among those 20 people equally to get (70,000)/20 = 3500 dollars per person.
Ahmad saves $2500 of his $3500 prize, leaving 3500-2500 = 1000 dollars leftover. This is the amount he donates.

Look at the sequence of numbers.
6 12 18 24
a Write down the next number in the sequence.
b Write down the term-to-term rule.
C Write down the position-to-term rule.
Answer:
Here we have the sequence:
6, 12, 18, 24
We can assume that this is an arithmetic sequence, this is, the difference between any two consecutive terms is always the same, D.
To check this, let's find the difference between the consecutive terms:
12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
So we can conclude that this is an arithmetic sequence, and the difference between any two consecutive terms is always 6.
a) Then the next number in the sequence will be equal to the previous number plus 6, this is:
24 + 6 = 30
The next number in the sequence is 30
b) The term-to-term rule is the rule that defines the n-th term based on the previous terms.
Here we already know that each term in this sequence is the previous one plus six, so we can write this as:
Aₙ = Aₙ₋₁ + 6
c) The position-to-term rule is the general one.
Here we need to know that, the first term, A₁ = 6
Then, the n-th term will be A₁ plus (n - 1) times 6.
Then the rule is:
Aₙ = A₁ + (n - 1)*6
Replacing A₁ by its value, the rule becomes:
Aₙ = 6 + (n - 1)*6
To find the surface area of the pyramid, in square inches, Vikram wrote (33.2) (34.2) + 4 (one-half (34.2) (28.4)). What error did Vikram make? He used the same expression for the area of all four lateral faces. He used the wrong expression to represent the area of the base of the pyramid. He used the wrong value as the height when he found the area of the lateral faces. He used an expression for surface area that only finds the total area of three faces.
Answer:
B. He used the wrong expression to represent the area of the base of the pyramid.
Step-by-step explanation:
Given
See attachment for pyramid
[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]
Required
Vikram's error
The surface area of a square pyramid is:
[tex]Area = Base\ Area + 4 * Area \triangle[/tex]
Where
[tex]Base\ Area = Length * Length[/tex]
[tex]Base\ Area = 34.2 * 34.2[/tex]
[tex]4 * Area \triangle = 4 * \frac{1}{2} * Base * Height[/tex]
[tex]4 * Area \triangle = 4 * \frac{1}{2} * 34.2 * 28.4[/tex]
So:
[tex]Area = Base\ Area + 4 * Area \triangle[/tex]
[tex]Area = 34.2 * 34.2 + 4 * \frac{1}{2} * 34.2 * 28.4[/tex]
By comparing the calculated expression with
[tex]Area = (33.2)(34.2) + 4 * \frac{1}{2} * 34.4 * 28.4[/tex]

In the month of September, a bird population increased by a factor of 1.25 every day for those 30 days. The function below shows the number of birds, f(x), after x days:
Answer:
0 ≤ x ≤ 30
Step-by-step explanation:
In the month of September, a bird population increased by a factor of 1.25 every day for those 30 days. The function below shows the number of birds, f(x), after x days:
f(x) = 250(1.25)ˣ
Which of the following is a reasonable domain for the function?
0 ≤ x ≤ 250
0 ≤ x ≤ 30
All positive integers greater than 100
All real numbers
Solution:
Given that f(x) = 250(1.25)ˣ, where x is the number of days and f(x) is the population of the birds after x days. This means that at the beginning of the month of September (i.e. at x = 0), the population of the birds was 250. And as each day goes by, the population of the bird increases by a factor of 1.25.
The domain of a function is the set of all possible independent variables. In this case the number of days (x) is the independent variable. Since in the month of September there are 30 days, therefore the domain is:
0 ≤ x ≤ 30
Carlos makes a 15% commission on the mattresses that he sells to customers. If he sells $8,500 worth of mattresses, what is his commission?
Answer:
Net commission= $1,275
Step-by-step explanation:
Giving the following information:
Sales= $8,500
Sales commission rate= 15% = 0.15
To calculate the net commission, we need to use the following formula:
Net commission= sales * Sales commission rate
Net commission= 8,500 * 0.15
Net commission= $1,275

The sphere at the right fits snugly inside a cube with 18-in. edges. What is the approximate volume of the space between the sphere and cube?
Answer:
2,778 in³
Step-by-step explanation:
Volume cube
v = 18³
v = 5,832
Volume sphere
v = (4/3)π9³
v = 3,053.6280592893
Volume space
v = 5,832 - 3,053.6280592893
v = 2,778.3719407107
2,778 in³
Answer:
Step-by-step explanation:
We need to first find the volume of the cube, then subtract from it the volume of the sphere. This is what we are being asked to find. First, the volume of the cube is length times width times height. Since this is a cube, all of the sides are the same length, making the volume
V = 18³ so
V = 5832 inches cubed. Now for the sphere.
The formula for the volume of a sphere is
[tex]V=\frac{4}{3}\pi r^3[/tex] and we will use 3.1415 for π.
[tex]V=\frac{4}{3}(3.1415)(9)^3[/tex] which gives us
V = 3053.538
Subtracting the volume of the sphere from the volume of the cube:
V = 5832 - 3053.538
V = 2778.462 inches cubed
