Answer:
An electronics company can be produce 350 transistors and 340 computer chips, they can´t produce resistors.
Step-by-step explanation:
1. We will name the variables for transistors, resistors and the computer chips.
a = Transistors
b= Resistors
c = Computer chips
2. We propose three linear equations, one for the copper, one for the zinc and one for the glass.
3. We write the matrix form as Ax=d
With this formula the solution of x is or
4. We will find the inverse matrix using the formula:
a. det A
b.
c.
5. As or , the solution of x is:
<u><em>Therefore:</em></u>
<u><em>a= 350 Transistors</em></u>
<u><em>b=0 Resistors</em></u>
<u><em>c=340 Computer chips</em></u>
Answer:
D) 111
Step-by-step explanation:
In order to find ∠KJH we must find the measure of arc KH
Note that ∠KJH is a central angle and arc KH is the arc it intercepts
Because ∠KJH is a central angle it equal the measure of its intercepted arc
Thus, ∠KJH = arc KH
J is a circle that is made up of 3 arc; KL, LH and KH
If you didn't know the sum of the arcs in a circle = 360°
Which means that arc KL + arc LH + arc KH = 360
If arc KL = 136 and arc LH = 113
Then 136 + 113 + arc KH = 360
^ ( note that we just created an equation that we can use to
solve for arc KH )
We now solve for arc KH
136 + 113 + arc KH = 360
* combine like terms *
136 + 113 = 249
we now have 249 + arc KH = 360
* subtract 249 from each side *
249 - 249 cancels out
360 - 249 = 111
We're left with arc KH = 111°
Like stated previously arc KH = ∠KJH
Hence, ∠KJH = 111°
X = -6
y= -34
Hope this helps!
