What does h(40) = 1400 mean in terms of the problem
Answer:
The correct option is B.
Step-by-step explanation:
From the given table it is clear that left column represents the hours of training and the right column represents the Monthly pay.
Here, left column is input (x) and right column is output (y). It means a worker with x hours of training is paid $y per month.
[tex]h(40)=1400[/tex]
In this equation the value of y is 1400 at x=40.
A worker with 40 hours of training is paid $1400 per month.
Therefore, correct option is B.
Factor −1/3
out of −1/3x−8
Answer:
The factor form is [tex]-\frac{1}{3}x-8=-\frac{1}{3}(x+24)[/tex]
Step-by-step explanation:
To find : Factor [tex]-\frac{1}{3}[/tex] out of [tex]-\frac{1}{3}x-8[/tex]
Solution :
Taking the term common means we the number multiply inside give you the same result.
Taking [tex]-\frac{1}{3}[/tex] out of [tex]-\frac{1}{3}x[/tex] is left with
[tex]\frac{-\frac{1}{3}x}{-\frac{1}{3}}=x[/tex]
Taking [tex]-\frac{1}{3}[/tex] out of [tex]8[/tex] is left with
[tex]\frac{8}{-\frac{1}{3}}=-8\times 3=-24[/tex]
So, [tex]-\frac{1}{3}x-8=-\frac{1}{3}(x-(-24))[/tex]
[tex]-\frac{1}{3}x-8=-\frac{1}{3}(x+24)[/tex]
The factor form is [tex]-\frac{1}{3}x-8=-\frac{1}{3}(x+24)[/tex]

What is the unit rate for 768.57 m 41.1 h? Enter your answer, as a decimal, in the box.
Final answer:
To find the unit rate, divide 768.57 meters by 41.1 hours resulting in a unit rate of 18.70 meters per hour.
Explanation:
The question asks for the unit rate of 768.57 meters over 41.1 hours. To calculate this, divide the distance by the time:
First, write the given ratio as a fraction. 768.57 m over 41.1 h.Second, divide 768.57 by 41.1 to find the unit rate in meters per hour. 768.57 m ÷ 41.1 h = 18.70 m/h (rounded to two decimal places as per the significant figures in the original distance).The division, 768.57 m ÷ 41.1 h, yields a unit rate of 18.70 m/h (rounded to two decimal places to match the precision of the original distance). Hence, the unit rate for this scenario is 18.70 meters per hour.
Therefore, the unit rate is 18.70 meters per hour.

The coordinates of the midpoint of AC¯¯¯¯¯ are (, b2 ).
The coordinates of the midpoint of BD¯¯¯¯¯ are ( a+c2 , ).
The midpoints of the diagonals have the same coordinates.
Therefore, AC¯¯¯¯¯ and BD¯¯¯¯¯ bisect each other.
Answer:
Step-by-step explanation:
1). Coordinates of point C will be
x - coordinates = [Distance of B from the origin + Distance of D from y axis]
= (a + c)
y - coordinates = (Distance of D from x - axis)
= b
Therefore, coordinates of C will be [(a + c), b]
2). Coordinates of the midpoint of AC = [tex][\frac{(a+c)+0}{2}, \frac{b+0}{2}][/tex]
= [tex][\frac{(a+c)}{2}, \frac{b}{2}][/tex]
[Since coordinates of the midpoint of (x, y) and (x', y') are denoted by ([tex]\frac{x+x'}{2},\frac{y+y'}{2}[/tex])]
3). Coordinates of the midpoint of BD = [tex][\frac{(a+c)}{2}, \frac{b+0}{2}][/tex]

Every week, Mr. Kirkson uses 3 1/6 gallon of water to water every 1/3 square foot of his garden. How many gallons of water does Mr. Kirkson use per square foot to water his garden each week?
3 1/6 / 1/3 =
19/6 / 1/3 =

This problem can be solved by a simple rule of three.
We have that 1/3 = 0.33 square foot of his garden uses uses 3 1/6 = 19/6 = 3.167 gallons of water. How many are used per square foot? So:

The table shows the number of miles driven over time time 4,6,8,10 distance 232, 348, 464, 580
Express the relationship between distance and time and simplified form as a unit rate. Determine which statement correctly interprets this relationship
Final answer:
The relationship between distance and time is that the vehicle travels at a constant speed of 58 miles per hour, meaning for every hour of driving, the distance covered is 58 miles.
Explanation:
To express the relationship between distance and time in simplified form as a unit rate, we divide the distance by the time for every given value. Based on the provided data, for each time interval, the distance driven is 58 times the number of hours.
Therefore, the unit rate or speed is 58 miles per hour. This can be explained by the fact that at each time interval, the distance increases by 116 miles every 2 hours, which simplifies down to 58 miles per hour (58 miles/1 hour).
To interpret this, one could say that for every hour of driving, the vehicle covers a distance of 58 miles. Thus, speed or velocity is the constant rate at which distance is covered over time in this scenario.
A cruise ship is traveling at a speed of 20 knots . A knot is approximately equal to 1.151 miles per hour. What is the approximate speed the ship is traveling in yards per second ? Round to the nearest tenth.
The cruise ship's speed, starting at 20 knots, can be translated to approximately 11.2 yards per second when converted to miles per hour, yards, and seconds.
Explanation:To find the cruise ship's speed in yards per second, we first need to convert knots to miles per hour by utilizing the equivalence of 1 knot to 1.151 miles per hour. Therefore, the ship is traveling approximately 20 * 1.151 = 23.02 miles per hour.
Next, we need to convert the ship's speed from miles per hour to yards per second. There are 1760 yards in a mile and 3600 seconds in an hour. The conversion will be 23.02 miles/hr * 1760 yards/mile divided by 3600 seconds/hr, which results in an approximate speed of 11.2 yards per second when rounded to the nearest tenth.
