Cada semana de los últimos 3 años Lucía ha hecho 120 km en bicicleta y cada mes 100 km corriendo y 15 km nadando. Debe cambiar la bicicleta cada 20.000 km. ¿Tiene que cambiarla ya?

Answers

Answer:

Lucía no tiene que cambiar ya la bicicleta porque ha recorrido 18,720 km.

Step-by-step explanation:

Para determinar la respuesta tienes que encontrar la cantidad de km que Lucía ha hecho en 3 años multiplicando los 120 km que hace a la semana por la cantidad de semanas que hay en 3 años. Para determinar las semanas, tienes que considerar que en 1 año hay 52 semanas:

Semanas=52*3= 156 semanas

120*156=18,720 km

De acuerdo a esto, la respuesta es que Lucía no tiene que cambiar ya la bicicleta porque ha recorrido 18,720 km.

What is 3/4 divided 5/16 in its simplest form?

Answers

Step-by-step explanation:

3/4÷5/16

3/4×16/5

=12/5(2 2/5)

(3/4) divided by (5/16) in its simplest form is 12/5.

To divide two fractions, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by flipping the numerator and the denominator.  So, to divide (3/4) by (5/16), you can multiply (3/4) by the reciprocal of (5/16):

(3/4) ÷ (5/16) = (3/4) * (16/5)

Now, multiply the numerators and denominators:

Numerator: 3 * 16 = 48

Denominator: 4 * 5 = 20

3/4) ÷ (5/16) = 48/20

To simplify this fraction, find the greatest common divisor (GCD) of the numerator and the denominator, and then divide both by the GCD:

GCD of 48 and 20 is 4.

(48/4) ÷ (20/4) = 12/5.

Jasmine gets paid to do chores around her house. She earns $3.00 every 20 minutes that she cleans the gutters. She earns $3.60 every 20 minutes that she mows the lawn. It took her 40 minutes to clean the gutters and 2 hours to mow the lawn. How much money did Jasmine earn?

Answers

Answer:

$24

Step-by-step explanation:

Step one:

given data

we are told that she earned $3 every 20minute for gutter cleanup

and for mow, she earns $3.6 every 20 minutes.

Step two;

1. For a 40 minutes gutter cleanup she will make

=3*40/20

=3*2

=$6

1. For a 2 hours mow she will make

2 hours is 120 minutes

=3.6*120/20

=3*6

=$18

So in total she earned 6+18= $24

Jo's mother, Anne, is four times as old as Jo. In four years time, Anne will be three times as old as Jo. How old is Jo? (this is an easier version of a riddle we'll do in AP CS)

Answers

Answer:

Jo's age = x = 8 years

Step-by-step explanation:

Let

Jo's age = x

Jo's mother, Anne's age = 4x

In four years time, Anne will be three times as old as Jo.

Jo's age =3( x + 4)

Jo's mother, Anne's age = 4x + 4

How old is Jo?

Equate Jo's age and his mother's age

3(x + 4) = 4x + 4

3x + 12 = 4x + 4

3x - 4x = 4 - 12

-x = - 8

Divide both sides by -1

x = 8

Therefore,

Jo's age = x = 8 years

Answers

Answer:

C. 0.99493

Step-by-step explanation:

Hope this helps!

The probability that the person will not die in the next year should be considered as the 0.00943.

Calculation of the probability:

Since

the probability that a person will die in the next year is 507/100,000

So, it can be like

[tex]= (100,000 - 507) \div 100,000[/tex]

= 0.99493

hence, The probability that the person will not die in the next year should be considered as the 0.00943.

Mr. Randall, a salesperson, earns a weekly salary of $300 plus a commission of 7% of
his weekly sales of merchandise. Last week, Mr. Randall earned $426. This can be
represented by the equation below, where s represents his total sales, in dollars, for
the week.
$300 + $0.07s = $426
How many dollars worth of merchandise did Mr. Randall sell last week?

Answers

Answer:

-3

Step-by-step explanation:

Based on his weekly salary and commission, we can calculate that Mr. Randall sold goods worth $1,800.

In the formula given, sales is represented as s. To find the total sales, you can solve the equation:

300 + 0.07s = 426

0.07s = 426 - 300

s = 126 / 0.07

= $1,800

In conclusion, Mr. Randall sold $1,800 worth of goods.

3. A student wrote a book which she plans to sell online for $13 per copy. Her total expenses were $85. Which function can be used to find the profit in dollars, d, when the student sells C, copies of the book?​

Answers

Answer:

Her profit in dollars is;

d = 13c - 85

Step-by-step explanation:

Mathematically,

profit = sales - cost price

She sells at $13 per copy

so for c copies, total sales amount will be 13 * c= $13c

So the profit d in dollars will be;

d = 13c - 85
