Verizon [17]

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

In this rectangular box, EF = 16, FD = 5, and DB = 30. Find AF.

AVprozaik [17]

Answer:

FA = 25.87

Step-by-step explanation:

Given: BD = 30 , DF = 5 , EF = 16

To find: FA

Rectangular box is a Cuboid.

Figure attached.

AB = FE = 16

So,

In ΔADB

using Pythagoras theorem,

$DB^2=AB^2+AD^2\\30^2=16^2+AD^2\\900=256+AD^2\\AD^2=900-256\\AD^2=644\\AD=\sqrt{644}\\AD=2\sqrt{161}$

Again using Pythagoras theorem in Δ ADF we get

$FA^2=DF^2+AD^2\\FA^2=5^2+(2\sqrt{161})^2\\FA^2=25+644\\FA^2=669\\FA=\sqrt{669}\\FA=25.87$

Therefore, FA = 25.87

De un grupo de 22 estudiantes hay 13 que practican natación y 10 practican atletismo y 2 que no practican nada . ¿Cuántos practi

Goshia [24]

Usando conjuntos de Venn, se encuentra que 7 estudiantes practican solo atletismo.

Los conjuntos son:

Conjunto A: Estudiantes que practican natación.

Conjunto B: Estudiantes que practican atletismo.

Hay que:

13 que practican natación, o sea, $A = 13$ .

10 practican atletismo, o sea, $B = 10$ .

2 que no practican nada, o sea $A \cup B = 22 - 2 = 20$ .

La cantidad que practica ambos es:

$A \cap B = A + B - A \cup B$

$A \cap B = 13 + 10 - 20$

$A \cap B = 3$

Solo atletismo es:

$B - A \cap B = 10 - 3 = 7$

7 estudiantes practican solo atletismo.
