Answer: 4π/15, 4π/3 and 28π/15 (in radians)
Step-by-step explanation:
Recall that
=
This implies that
Therefore the values of between 0 and 2π are 48, 240 and 336. (All in degrees)
48 degrees= 4π/15 rad
240 degrees =4π/3 rad
336 degrees = 28π/15 rad
Answer:
La situación está representada por el siguiente sistema:
Donde:
- Cantidad de rosas vendidas semanalmente.
- Ganancia semanal, medida en dólares.
Step-by-step explanation:
De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:
(1)
(2)
Donde:
- Cantidad de rosas vendidas semanalmente.
- Ganancia semanal, medida en dólares.
We will see that 20 children can get a serving.
<h3>How to divide fractions?</h3>
To see how many children can get a serving we need to take the quotient between the total amount of grapes and the amount of grapes needed for each serving.
We know that there are 5 bunches of grapes, and each serving needs 1/4 bunches, then we need to solve:
Notice that we can write 5 as a fraction:
5 = 5/1
then:
Now, the two numbers in the middle (both ones) remain on the denominator, while the other 2 conform the numerator, then we have:
So 20 children can get a serving.
