El padre tenía 29 o 28 años cuando nació el autor de la pregunta.

Step-by-step explanation:

English Translation

My grandmother gave birth to my father, when she was under 20 years old, and I was born when my father was over 25 years old, if my father is now under 45 years old and I was in my fourth year of high school, how old is my father when I was born.

Solution

Assuming that the author of the question is a typical fourth year high school student.

The age of fourth year high school students normally range from 16 to 17.

The father is currently 45 years old, so the age of the father when the author of the question was born is given as

(45 - 16) or (45 - 17)

= 29 or 28 years old.

which satisfies the condition given in the question that the father was more than 25 years old!

Hope this Helps!!!

ten years ago, the ratio of two brothers was 1:4. fourteen years from now, the ratio will be 4:7. What is the ratio of their pre

andrey2020 [161]

The ratio of their age is 3:7.

Step-by-step explanation:

Given,

10 years ago, the ratio of two brothers was 1:4

After 14 years the ratio will be 4:7

To find the ratio of their present age.

Let,

10 years age their age was x and 4x

So, now their age is (x+10) and (4x+10)

14 years from now their age will be (x+10+14) and (4x+10+14)

That is x+24 and 4x+24

According to the problem,

x+24 : 4x+24 = 4:7

or, $\frac{x+24}{4x+24} = \frac{4}{7}$

or, 7(x+24) = 4(4x+24)

or, 7x+168 = 16x+ 96

or, 16x-7x = 168-96

or, 9x = 72

or, x = 8

Hence,

Their present age is (8+10) and (4×8+10) = 18 and 42

Hence,

The ratio of their age is 18:42 = 3:7

Find the distance between the points <br> (-8,-6) and (4, 10)

never [62]

Answer:

d=20

Step-by-step explanation:

To find the distance between 2 points we use the distance formula

d = √(x2 - x1)²+(y2 - y1)²

The given points are (x1= -8, y1 = -6) and (x2 = 4, y2 = 10).

Substitute the given points into the distance formula.

d = √(4 + 8)²+(10 +6)²

d = √144+252

d= √400

d = 20
