What time is 8 hours and 51 minutes before 11:13 P.M.?
8 hours and 51 minutes before 11:13 P.M. is 2:22 P.M.
To find what time it is 8 hours and 51 minutes before 11:13 P.M., we need to subtract 8 hours and 51 minutes from 11:13 P.M. Here's a step-by-step explanation:
Start with the minute subtraction. Since 13 minutes is less than 51 minutes, we need to borrow one hour from the 11 P.M. So, we change 11:13 P.M. to 10:73 P.M.Now, subtract the minutes: 73 - 51 = 22 minutes. So now we have 10:22 P.M.Next, subtract the hours: 10 P.M. - 8 hours = 2 P.M.Thus, 8 hours and 51 minutes before 11:13 P.M. is 2:22 P.M.
by graphing the system of constraints find the values of x and y that maximize the object function.
Answer with Step-by-step explanation:
The solution of system of equations is all those values of x and y which satisfy both the inequalities or the points which lie in the region common between both the inequalities.
N=100x+40y
The optimal solution will be find from the points which lie on the extreme end of the region common between the inequalities i.e. (2,6), (0,8) or (5,0)
(x,y)=(2,6)
N=100×2+40×6
N= 200+240
N=440
(x,y)=(0,8)
N=100×0+40×8
N= 0+320
N=320
(x,y)=(5,0)
N=100×5+40×0
N= 500+0
N=500
Hence, optimal solution is:
(5,0)

The line passes through the points ( 7, -7) and ( 6, -5) a. y = -2x + 7 c. y = -2x - 7 b. y = 2x - 21 d. y = 2x - 7
Final answer:
The equation of the line passing through the points (7, -7) and (6, -5) is determined by finding the slope, which is -2, and then using the point-slope formula. However, the correct equation y = -2x + 21 is not listed among the student's provided options.
Explanation:
The student's question asks for the equation of a line that passes through two given points: (7, -7) and (6, -5). To find the equation of the line, we first need to determine its slope.
We use the formula for slope which is (change in y) / (change in x), often written as (y2 - y1) / (x2 - x1)
Slope = (-5 - (-7)) / (6 - 7) = 2 / -1 = -2. Therefore, the slope (m) is -2.
With the slope known, the next step is to use the point-slope form of the line equation, which is y - y1 = m(x - x1). Substituting one of the points and the slope, we get y - (-7) = -2(x - 7). Simplifying this gives us y = -2x + 14 + 7, which simplifies further to y = -2x + 21.
Therefore, among the options provided by the student, none of the equations match precisely, which means either there is a mistake in the question's options or in the calculation. However, the closest match, by the slope, would be option y = -2x - 7, considering only the slope and not the intercept.

Write the conversion factor for converting meters to centimeters.
Answer:
1 meter = 100 centimeter
Step-by-step explanation:
A conversion factor is a numerical value that we use to change one set of unit to another set by performing actions like multiplication or division. When we are converting something, we must use the appropriate conversion factor of an equal value. Few conversions are :
1 meter = 100 centimeter
1 kilometer = 1000 meter
1 foot = 12 inches
1 gallon = 4.54 liters
We want the conversion factor for converting meters to centimeters. this is 1 m = 100 cm.
Simplify 8(xy + 8) + 1
Final answer:
The expression 8(xy + 8) + 1 simplifies to 8xy + 65 by applying the distributive property and combining like terms.
Explanation:
The question asks to simplify the expression 8(xy + 8) + 1.
To simplify this expression, we need to apply the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. Hence, we distribute the 8 across the terms inside the parentheses:
8 × xy = 8xy8 × 8 = 64After distributing we combine the like terms:
8xy + 64 + 1
Then we combine the numerical terms:
8xy + 65
So, the expression simplifies to 8xy + 65. This is the final simplified form of the given expression.
What is the slope of a line parallel to the line 4x - 7y = -14?
Final answer:
The slope of a line parallel to the line 4x - 7y = -14 is determined by converting the equation to slope-intercept form, revealing that the slope is 4/7. Thus, any line parallel to it will have the same slope of 4/7.
Explanation:
The slope of a line parallel to the line 4x - 7y = -14 is first determined by rewriting the given line in slope-intercept form (y = mx + b), where m represents the slope. For the line 4x - 7y = -14, we can solve for y to find the slope:
Add 7y to both sides: 4x = 7y - 14.
Then add 14 to both sides: 4x + 14 = 7y.
Finally, divide every term by 7 to solve for y: (4/7)x + 2 = y.
The slope of the line is 4/7. Since parallel lines have equal slopes, any line parallel to the given line will also have a slope of 4/7.

List all of the number sets that contain the number 15.
A.
rational numbers and integers
B.
rational numbers, integers, and natural numbers
C.
rational numbers, integers, and whole numbers
D.
rational numbers, integers, natural numbers, and whole numbers
Final answer:
The number 15 belongs to several sets of numbers: it is a rational number, an integer, a whole number, and a natural number. Therefore, the correct answer to which sets contain the number 15 is D. Rational numbers, integers, natural numbers, and whole numbers.
Explanation:
Number sets form a hierarchy where certain numbers fit into multiple categories based on their characteristics. Starting from the broadest categories, we have complex numbers, which include all numbers with a real and imaginary part. However, the number 15 does not have an imaginary part, so we look to smaller sets.
The real numbers include all the values that can be found on the number line, which includes rational numbers (like fractions), irrational numbers (like √2), integers, whole numbers, and natural numbers. The number 15 is a real number because it can be found on the number line, but it is also specifically a rational number, an integer, a whole number, and a natural number because:
As a rational number, it can be expressed as the ratio of two integers, specifically 15/1. As an integer, it is a whole number and does not have a fractional or decimal part. As a whole number, it is a non-negative integer, starting from 0 and moving upwards. As a natural number, it is a positive integer used for counting (1, 2, 3, ...).
Therefore, the correct answer to the question is D. Rational numbers, integers, natural numbers, and whole numbers all contain the number 15.
