The actual value = 25.7 ml
The error = 15.6%
This means that the value of error = 0.156 * 25.7 = 4.0092 ml
Now, the error percentage found means that the student got the value either greater than the actual one with the value of error or less than the actual one with the value of error.
This means that the two possible readings are:
either : 25.7 + 4.0092 = 29.7092 ml
or : 25.7 - 4.0092 = 21.6908 ml
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
Answer: b+95+34=180, b+129=180, 51
Step-by-step explanation:
b+95+34=180 works because the angles add to form a straight angle.
From this, we can obtain b+129=180 by adding the two constants.
Subtracting 129 from both sides, we get b=51.
Answer:
2x^2 – 5x – 3
Step-by-step explanation:
<u>Apply FOIL method: </u>
=x*2x+x*1+(-3)*2x+(-3)*1
<u>Apply minus-plus rules:</u>
=2xx+1*x-3*2x-3*1
Simplify:
=2x^2 – 5x – 3
Your Answer Is 2x^2 – 5x – 3
