Answer:
39
Step-by-step explanation:
If 8 out of 21 are WOODWINDS, we can say:
21 - 8 = 13
13 out of 21 ARE NOT woodwinds.
This is the ratio.
Now, there are 63 total instruments. We need to find how many ARE NOT woodwinds. We equate the ratio found (13 out of 21) with total 63 instruments and find "x" [let x be number of instruments that are NOT woodwinds].
Shown below:
Hence, out of 63 instruments, we can say that 39 are not woodwinds
The question is probably incomplete. What i am assuming is that the person might ask for the previous ratio or the total number of pens and pencil in the drawer.
So if it is the previous ratio it obviously would be 47 - 5 : 17 -3 so 42 : 14 and in case he or she is asking for the total number of pens and pencils in the drawer before so they were 42 + 14 hence 56.
Hi there!
The equation of any line perpendicular to
is
Therefore, in this situation, the formula of the line would be
Given that the line passes through the point (6, 4) we get
Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
Answer:
c=3r
Step-by-step explanation:
Concluimos que a partir de 21 piezas se gana más en la empresa B.
<h3>
¿Cuanto debe vender para que le paguen más en la empresa B?</h3>
Si definimos el número de piezas vendidas como x, la cantidad que le pagan en la empresa A es:
A(x) = $6000 + $20*x
Y lo que le pagan en la empresa B es:
B(x) = $6000 + x^2
Queremos ver para que valor de x, se da que B(x) > A(x).
Entoces resolvamos esa inequación.
6000 + 20*x < 6000 + x^2
20x < x^2
20 < x
x debe ser más grande que 20, entonces concluimos que a partir de 21 piezas se gana más en la empresa B.
