Answer:
they are different because of the mode sign on the second 's',
which if you are wondering what it stands for,
it represents only the magnitude of the value needed, not its sign,
let the assumed value of s be -5,
for example iin the first case, s < 3
hence s = -5, and it is true for s < 3
OR
if we take the second case, lsl < 3
that would be s = 5 [ not -5], which would not be true for lsl < 3
i hope u understood it,
if any more questions...please ask :)
D. When you do the math, the results to everything should be t=9. D is the only outlier. Therefore, D is the answer in this case.
Answer:
No it does not represent a function
Step-by-step explanation:
It fails the vertical line test..
Assume that
a and b = the two legs of the right triangle.
c = the hypotenuse.
The area of the right triangle is 750 yd², therefore
(1/2)*a*b = 750
ab = 1500 (1)
The perimeter is 150yd, therefore
a + b + c = 150 (2)
Let the side fenced with wood be a, at $5/yd. Sides b and c are fenced with steel at $10/y. The total cost is $1200, therefore
5a + 10b + 10c = 1200
or
a + 2b + 2c = 240 (3)
From (2), obtain
c = 150 - a - b (4)
Substitute (4) into (3)
a + 2b + 2(150 - a - b) = 240
-a + 300 = 240
a = 60
From (1), obtain
60b = 1500
b = 25
From (4), obtain
c = 150 - 60 - 25 = 65
Answer:
A. The length of the leg fenced with wood is 60 yd.
B. The length of the leg fenced with steel is 25 yd.
Let the planned number of parts per hour = x
<span> Then the planned number of parts for the day = 8x
</span><span> By finishing 4 more parts in an hour than was planned (x + 4) he fulfilled his daily task in 6 hours.
</span><span> So he finished 6(x + 4) parts that day.
</span><span> 6(x + 4) = 8x
</span><span> 6x + 24 = 8x
</span><span> 2x = 24
</span><span> x = 12 </span>
