75 out of 300 oranges in a basket are bad. what percent age of the oranges are (a) bad (b)good
Likurg_2 [28]

Answer:

a) 25% are bad

b) 75% are good

Step-by-step explanation:

We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).

300 - 75 = 225 good oranges.

So to find the percentage we have to take the selected amount divided by the total amount.

Bad Apples:                               Good Apples:

75 / 300 = 0.25                          225/300 = 0.75

However, that's a decimal or <em>a number out of 1, </em>we need a percent or <em>a number out of 100.</em> So we have to multiply both numbers by 100.

Bad Apples = 25%

Good Apples = 75%

Svetllana [295]

Answer:

The father was either 29 or 28 years old when the author of the question was born.

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!!!

In Spanish/En español

Asumiendo que el autor de la pregunta es un típico estudiante de secundaria de cuarto año.

La edad de los estudiantes de cuarto año de secundaria normalmente oscila entre 16 y 17.

El padre tiene actualmente 45 años, por lo que la edad del padre cuando nació el autor de la pregunta se da como

(45 - 16) or (45 - 17)

= 29 o 28 años.

que satisface la condición dada en la pregunta de que el padre tenía más de 25 años!

¡¡¡Espero que esto ayude!!!

Jane needs 180 centimeters of green cloth and 240 centimeters of red cloth to make her holiday wreath. If she only had the money
Sidana [21]

Answer: She brought home 350 centimeters in total

Step-by-step explanation: The question specifies that Jane only had enough money to buy 5/6 of the materials she needed to make her wreath. For her wreath, she would need 180 centimeters of green cloth. However since she can only afford 5/6 of this, what she would end up with is

Green cloth = 180 x 5/6

Green cloth = (180 x5)/6

Green cloth = 900/6

Green cloth = 150 centimeters

Also she would need 240 centimeters of red cloth and since she can only afford 5/6 of the total, she would end up with

Red cloth = 240 x 5/6

Red cloth = (240 x5)/6

Red cloth = 1200/6

Red cloth = 200 centimeters

If she ended up with 150 centimeters of green cloth and 200 centimeters of red cloth, the total length of cloth she would bring home would be

Total = 150 + 200

Total = 350 centimeters
