Answer:
.2
Step-by-step explanation:
3:15 to 4:30 is 75 minutes
she had to assemble 15 since there were already 67 made
divide 15/75
.2 per minute
Answer:
a)
b) and c)
See explanation below
Step-by-step explanation:
a)
The combined resistance R is a function of the the two
parallel resistances
So
and we have
Similarly,
b)
If we divide both the numerator and denominator by 
in the expression for R, we get
hence, if we held 
constant and increase the fraction 
gets smaller and so does the denominator of R, as a consequence R gets larger.
When is very large, the denominator of R is close to 1, so R is close to
c)
By a symmetric reasoning, we see that R gets larger when holding constant and increases.
In this case, R gets closer to as grows.
Answer: y= -x + 7
Solution:
Step 1 : find the slope using the equation using the pair of coordinates that are given i.e A (−7,14) B (−21,28) ( name them A and B respectively so they can be easily named as x1, y1 and x2,y2 respectively)
m = y2-y1/x2-x1
m = 28-14 / -21 -( -7)
m = 14 / -14
m = -1
Step 2 : Find the y intercept using the line of equation (use and one of the given coordinates either A or B)
Using A ( -7, 14)
y= mx+ b
14 = (-1)(-7) + b
14= 7 + b
14-7 = b
7 =b
So,
y=mx+b
Insert m and b
y= -x + 7
Answer:
12+8r
Step-by-step explanation:
2(6+4r) = 30r
If I am wrong, please let me know and I will do a re-correction
Solution:
<u>Simplify the equation and solve.</u>
- 89(54x − 36) + 2 = −34(−40 + 16x) + 90x
- => 4806x − 3204 + 2 = 1360 - 544x + 90x
- => 4806x = 1360 - 454x + 3202
- => 5260x = 4562
- => x = 4562/5260 = 2281/2630
The solution to the problem is 2281/2630.
