<h3>Given -:</h3>
change in emitter current, ∆l(E) = 4 mA
change in collector current,∆I(C) = 3.5 mA
<h3>To find -:</h3>
value of B
<h3>Solution :-</h3>
∆I(E) = ∆I(C) + ∆l(B), here ∆l(B) is the change in base current.
4 = 3.5 + ∆l(B)
∆I(B) = 0.5 mA
<h3>Now, B = ∆l (C) ÷ ∆l (B)</h3>
B = 3.5 ÷ 0.5
B = 7.0
<h3>so, the value of A = 7.0</h3>
Answer: m<VUT= 70 degrees
Step-by-step explanation:
120= 50+ ?
?=70
The tax is 6.5% OF the listed price. "OF" in math means multiply.
First convert the percentage to a decimal
6.5% = .065
Then multiply .065*813.95 = 52.90675. This is the tax.
Simply add the tax onto the cost
813.95 + 52.90675 = $866.86 (rounded)
Answer:
3
Step by Step:
Subtract the tip ($6) from the total ($39)
11x=33
Then divide 33 by 11, leaving you with the value of x.
x=3

Answer:
The initial value is $78
Step-by-step explanation:
Given

(weekly)
Required
Determine the initial value
The initial value is the amount he has in its bank account before making his weekly savings.
From the question, we have that his initial balance is $78.
Hence, the initial value is $78
However, his weekly balance can be expressed as:

Represent number of weeks with x; So, we have:
