If x+z=15 and w + y =10, what is the value of (3w+3y)(2x+2z)?
DiKsa [7]

Answer:

900

Step-by-step explanation:

Notice anything about (3w+3y)(2x+2z)?

It's basically equal to 3(w+z) times 2(x+z).

Since x+z=15 and w+y=10, you can plug in the numbers.

3(10) times 2(15)

= 30x30

=900

Hope this helps!!

Select the correct answer. A company manufactures computers. Function N represents the number of components that a new employee
professor190 [17]

The function which describes the difference of the number of computer components assembled per day by the experienced and new is D(t)=10t(2t+13)/[(t+4)(t+3)].

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Function N represents the number of components that a new employee can assemble per day.

N(t)=(50t)/(t+4)

Function E represents the number of components that an experienced employee can assemble per day.

E(t)=(70t)/(t+3)

In both functions, t represents the number of hours worked in one day. The function which represent the difference of the number of components assembled per day by the experienced and new employees is,

D(t)=\dfrac{70t}{t+3}-\dfrac{50t}{t+4}\\D(t)=\dfrac{70t(t+2)-50t(t+3)}{(t+4)(t+3)}\\D(t)=\dfrac{10t(7(t+4)-5(t+3))}{(t+4)(t+3)}\\D(t)=\dfrac{10t(7t+28-5t-15)}{(t+4)(t+3)}\\D(t)=\dfrac{10t(2t+13)}{(t+4)(t+3)}\\

Thus, the function which describes the difference of the number of computer components assembled per day by the experienced and new is D(t)=10t(2t+13)/[(t+4)(t+3)].

What is the total number of different routes that a fire
Pavlova-9 [17]

The total number of different routes that a fire truck can travel the m-distance from F to Z = 4 (Option C).

<h3 /><h3>What is a graph?</h3>

A graph refers to a diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.

Now,

Firstly, refer to the graph attached.

  • The graph can be used to manually calculate the number of routes that lead from F to Z.
  • F is four m-distances from Z.
  • Now, manually calculate the m-distance of the path from F to Z using the 4 boxes that represent it. We discover 6 distinct pathways, each with an m-distance of 4.

Hence, The total number of different routes that a fire truck can travel the m-distance from F to Z = 4 (Option C).
