Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Step-by-step explanation:
please answer and show step.
Answer:
i believe the answer is 25.
Step-by-step explanation:
this is because if a=how much money deposited after t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.
tell me if this is incorrect.
Answer:
25
Step-by-step explanation:
In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.

Answer:
Diagonals bisect each other.Diagonals are congruent.Diagonals are perpendicular.Diagonals bisect the anglesexplain how the following diagram demonstrates the pythagorean theorem?
Answer:
the largest block represents the hypotenuse which would be c² the smallest can either be a or b and the block thats left over will be the letter you didn't use for the small block so in terms the blocks represents a²+b²=c²
[tex]\bold{a^2+b^2=c^2}[/tex] is indeed the Pythagorean theorem. It implies that adding the hypotenuse square as well as the two sides of a right triangle equals the hypotenuse square.
Calculating value by using the Pythagorean theorem:The smallest side of the triangle in this instance contains 36 squares, which equals [tex]\bold{6^2}[/tex]. The triangle's bigger side has 64 (or [tex]\bold{8^2}[/tex]) squares. You get 100 by multiplying 36 and 64, which is the same as [tex]\bold{10^2}[/tex]. Using the formula [tex]\bold{a^2+b^2=c^2}[/tex], you should arrive at [tex]\bold{6^2+8^2=10^2}[/tex].Find out more information about the Pythagorean theorem here:

Using it's concept, it is found that the median of the data in the dot plot is 83.5.
What is the median of a data-set?The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
The dot plot gives the number of times each measure appears, hence in this problem, the data-set is composed by:
{81, 82, 83, 83, 84, 84, 85, 85}
Even cardinality, hence the median is the mean of the two middle elements, 83 and 84, hence:
M = (83 + 84)/2 = 83.5.
The median of the data in the dot plot is 83.5.

A group of friends wants to go to the amusement park. They have no more than $245 to spend on parking and admission. Parking is $9.25, and tickets cost $25.75 per person, including tax. Which inequality can be used to determine pp, the maximum number of people who can go to the amusement park?
Answer:
25.75x+9.25
Step-by-step explanation:
9.25 is the constant. You multiply the ticket by the amount of people to get ticket cost. Then you add ticket cost 9.25 to get final answer.
Inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
We have been given that the group of friends has no more than $245 to spend on parking and admission.
And the parking is $9.25, and tickets cost $25.75 per person, including tax.
Let the number of people would be p who can go to the amusement park,
So the inequality that expresses the relationship is
⇒ 9.25 + 25.75 × p ≤ 245
Therefore, inequality is 9.25 + 25.75 × p ≤ 245 which represents the maximum number of people who can go to the amusement park.
