-4/5 divided by 2
1) -1 3/5
2) -2/5
3) 1/2
4) 1 3/5
Answer: -2/5
Step-by-step explanation: It's -4/5 multiplied by 1/2 because you you have to find the reciprocal, so you flip 2, so it would become 1/2, then you multiply -4/5 and 1/2, which would get you -4/10, which can be reduced to -2/5. Hope this helps!

industrial costs A power plant is located near a river, where the river is 800 ft wide. Running a cable from the plant to a location in the city, 2 miles (mi) downstream on the opposite side, costs $ 180 per ft across the river and $ 100 per ft ashore along the riverbank .
a) Suppose the cable runs from the plant to point Q, on the opposite side, which is x ft from point P, directly opposite the plant. Write a function C (x) that indicates the cost of laying the cable in terms of the distance x.
b) Generate a table of values to determine if the cheapest location for point Q is less than 2000 ft or greater than 2000 ft from point P.
Answer:
See attached
Step-by-step explanation:
All answers in one graph, refer to attached
The function we need is
C(x) = 100(2*5280 - x) + 180[tex]\sqrt{800 +x^2}[/tex], where 2*5280= 2 milesTable included as well
The vertex is about x = 19 ft which corresponds the minimum cost
Any other value, including negative reveal greater cost
Note. there is a bit confusion over 2 miles or 2000 ft, but the graph is going to be same in shape and vertex for x, the value for cost will be differentWhich is equivalent to 56c^16/162c^3 squared after it has been simplified completely?

2. Find the product of 2/7 x 5/6
A. 5/21
B. 7/42
C. 9/16
D. 10/13
3. Find (-4/6) (7/10)
A. -28/45
B. -14/25
C. -7/50
D. 17/50
Multiply the numerators together and the denominators:
2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21
The answer is 5/21
-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50
This can reduce to -14/25
An object is moving at a speed of 7 feet per minute. Express this speed in meters per second.
Answer:
2.1 mpm
Explanation:
1ft = 0.3048 m
[tex]0.3048*7=2.1336[/tex]
The given speed in meters per second is 0.00356 m/sec.
Given that, an object is moving at a speed of 7 feet per minute.
We need to express this speed in meters per second.
How to convert feet per minute to meters per second?Feet per minutes. In SI units [tex]5.08 \times 10^{-3}[/tex] meters per second.
Meters per second is the base unit for measuring velocity or speed in the International System of Units (SI). Speed is a measure of distance travelled over time, velocity is speed in a given direction. 1 meter travelled over a period of 1 second = 1 m/s.
For an approximate result, divide the speed value by 1969.
Now, 7/1969=0.003555
≈0.00356
Therefore, the given speed in meters per second is 0.00356 m/sec.

In an assessment of the quality of the electrical power system, one measure of quality is the degree to which voltage fluctuations cause light flicker in the system. The perception of light flicker x when the system is set at 380kV was measured periodically (over 10-minute intervals). For transformers supplying heavy industry plants, suppose the light flicker distribution was found to follow (approximately) a normal distribution with % and . If the perception of light flicker exceeds %, the transformer is shut down and the system is reset. How likely is it for a transformer supplying a heavy industry plant to be shut down due to light flicker?

its a ratio and proportion:

Answer:
Kindly check explanation
Step-by-step explanation:
________A___ B___ C___ Total
Male____ 9___13___ 6____ 28
Female_ 20__ 19___ 2____ 41
Total___ 29__ 32___ 8____ 69
If one student is chosen at random,
Find the probability that the student got a C:
P(getting C) = (number of C's) / total number
P(getting C) = 8 / 69
Find the probability that the student was female AND got a "C":
P(female and C):
(number of female who got C / total number)
= 2 / 69
Find the probability that the student was male OR got an "B":
P(male OR B) :
(Number of males or B) = (28 + 32) - 13 = 47
= 47 / 90
find the probability that the student got a 'C' GIVEN they are female:______.
P(C given they are female) :
This is the proportion of females who got C
Total Number of females = 41
Females who got C = 2
Hence,
P(C given they are female) = 2 / 41
in the diagram the value of sin P is
You divide the opposite over the hypotenuse
sin(angle) = opposite/hypotenuse
With respect to reference angle P, the opposite side is QR = 5 since it is the leg furthest from the angle P.
The hypotenuse is always the longest side and always opposite the 90 degree angle (the largest angle of any right triangle).
