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.

A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places

Jet bought a computer that was 20% off. If the original price of the computer was $785, how much did Jet save? How much did Jet pay?
785·20%=157
785-157=628
Answer:
You will pay $628 for a item with original price of $785 when discounted 20%. In this example, if you buy an item at $785 with 20% discount, you will pay 785 - 157 = 628 dollars.

which answer choice is equivalent to the expression (x+2)^2 - 6x+2?
a. x^2 - 2x+8x
b. x^2 - 2x+6
c. x^2 - 6x+4
d. -5x^2 +6
Answer:
(x+2)^2 - 6x+2
(x+2)^2 = (x+2).(x+2)
= x(x+2) + 2(x+2)
= xx + x2 + 2x +4 ( x2 = 2x)
= x^2+ 4x +4
(x+2)^2 - 6x+2
x^2+ 4x +4- 6x+2
x^2+ 4x - 6x+2 +4
x^2- 2x+2 + 6 (b)

The value of a stock increases by 8% each year.
1. Explain why the stock value does not increase by 80% each decade.
2. Does the value increase by more or less than 80% each decade?
Answer:
if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.
The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.
If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.
What is Percentage Increase?The degree to which a value increases expressed in percent form is known as percentage increase.
Given that, The value of a stock increases by 8% each year.
a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade
b) Since, (108%)¹⁰ > 80%
Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.
Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade
