Answer:
4 7/15
Step-by-step explanation:
To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.
Electricity rates. The table to the right shows the electricity
rates charged by Better Than Lightning Utilities in the winter
months.
a. Write a piecewise definition of the monthly charge W(x) for a
customer who uses x kWh in a winter month.
b. Determine the graph of W(x)
Winter (November-June)
Base charge, $8.50
First 300 kWh or less at 0.0650/kWh
Over 300 kWh at 0.0850/kWh
The piecewise function for the monthly charge W(x) for a customer who uses x hours of electricity is given by:
W(x) = 50 + 0.0650x, 0 ≤ x ≤ 300.W(x) = 69.5 + 0.0850x, x > 300.The graph of the function is given at the end of the answer.
What is a piecewise-defined function?A piecewise-defined function is a function that has different definitions, depending on the input of the function.
For this problem, we have that:
The input is the number of kWh electricity used.The output is the monthly charge.The monthly charge is calculated differently according to the number of kWh of electricity used, divided into two cases as follows:
First 300 kWh : 0 ≤ x ≤ 300.More than 300 kWH: x > 300.For up to 300 hours, the base charge of $50 plus the hourly fee of $0.0650 is charged, hence:
W(x) = 50 + 0.0650x, 0 ≤ x ≤ 300.
For more than 300 hours, the customer is charge 50 + 300 x 0.0650 = $69.5, plus the hourly fee of $0.0850, hence:
W(x) = 69.5 + 0.0850x, x > 300.

The temperatures at sunrise and sunset are shown in the table. What was the temperature change on each day? On which day did the temperature change the most?
The temperature changes for each day are 32.12 °C (Day 1) and 33.02 °C (Day 2), respectively. The day 2 registered the highest temperature change.
How to analyze and interpret temperature changes
Herein we find a table with the temperatures at sunrise and sunset in two days and we need to determine the temperature change for each period and conclude in what day the change was the highest. The temperature change can be found by using the following formula:
ΔT = T' - T

What is the domain of g
Answer:
A
Step-by-step explanation:
The domain of g(x) is the set of all real numbers. Meaning that all the numbers between the min and max of g would be -7 ≤ x ≤ 7.
Find the domain and range of the function F(t) = sec(3.14t/4)
The domain of sec(3.14t/4) is all real numbers except 2+4n, where n is any integer and range of sec(3.14t/4) is [tex](\infty,-1] \cup [1,\infty)[/tex].
The Domain of a function f(x) is the set of all values for which the function is defined.
The Range of a function is the set of all values that f takes.
As, [tex]sec x=\frac{1}{cos x}[/tex] , so sec x is defined where [tex]cos x \neq 0[/tex].
It implies, sec(3.14t/4) is defined where [tex]cos(3.14t/4)\neq 0[/tex].
The cosine is 0 at [tex](2n+1)\frac{\pi }{2}[/tex] , where n is any integer.
Now, [tex]\frac{3.14t}{4} =\frac{(2n+1)\pi }{2}[/tex]
[tex]\frac{\pi t}{4} =\frac{(2n+1)\pi }{2}[/tex]
[tex]t=2(2n+1)\\t=2+4n[/tex]
Since, the range of cos x is [-1,1], so sec x will never be less than 1, but can grow infinitely large as cos x approaches 0.
Thus, The domain of sec(3.14t/4) is all real numbers except 2+4n, where n is any integer and range of sec(3.14t/4) is [tex](\infty,-1] \cup [1,\infty)[/tex].

The width of the rectangular painting painted by John is 24.15 inch.
What is referred as the rectangle?A rectangle is a quadrilateral with parallel sides that are equal to one another and all four vertices that are equal to 90 degrees. As a result, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal as well as parallel, it is also known as a parallelogram.For, the given question;
The perimeter of the rectangular painting painted by the John is 108.56 in.
The formula for the perimeter of the rectangle is;
Perimeter = 2(length + width)
Thus,
2(length + width) = 108.56
The rectangular painting is 5.97 in. taller than it is wide.
It means;
Length = 5.97 + width
Put the value in perimeter.
2(5.97 + width + width) = 108.56
11.94 + 4 width = 108.56
width = 24.155

When two lines intersect at a point then the angle between them can be expressed in terms of their slopes and is given by the following formula:
tan θ = |
|where
are the slopes of the line AB and CD respectively.
If
is positive then the angle between the lines is acute. If
is negative then the angle between the lines is obtuse.
Slope of Vertical Lines
Vertical lines have no slope, as they do not have any steepness. Or it can be said, we cannot define the steepness of vertical lines.
A vertical line will have no values for x-coordinates. So, as per the formula of slope of the line,
Slope, m = (y2 – y1)/(x2 – x1)
But for vertical lines, x2 = x1 = 0
Therefore,
m = (y2 – y1)/0 = undefined
In the same way, the slope of horizontal line is equal to 0, since the y-coordinates are zero.
m = 0/(x2 – x1) = 0 [for horizontal line]
Positive and Negative Slope
If the value of slope of a line is positive, it shows that line goes up as we move along or the rise over run is positive.
If the value of slope is negative, then the line goes done in the graph as we move along the x-axis.
Let R,Q,T be the points that divide the line into 3:4 equal parts
Let the Q = (x,y)
R(1, 2) and T(8, 23) ,
x = m1x1+m2x2/m1+m2
y = m1y1+m2y2/m1+m2
X= 3.1+4.8/7
x= 3+32/7
x=35/7

A bear can run 400 feet in 8 seconds.
A horse can run 290 feet in 5 seconds?
Which animal runs at the faster rate?
Horse runs at the faster rate i.e. at the rate of 58 feet per seconds.
According to the given question.
A bear can run 400 feet in 8 seconds.
A horse can run 290 feet in 5 seconds.
As we know that, the measurement of the speed at which something happens is called rate.
Therefore, form distance rate formula (rate = distance/time)
The rate of the bear = 400/8 = 50 feet/sec
And the rate of the horse = 290/5 = 58 feet/sec
Therefore, horse can run faster than bear.
Hence, horse runs at the faster rate i.e. at the rate of 58 feet per seconds.

What are maths operations?An operation is a function in mathematics that converts zero or more input values (also known as "operands" or "arguments") to a well-defined output value. The operation's arity is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied operations. A zero-arity operation, also known as a nullary operation, is a constant. The mixed product is an example of an arity 3 operation, also known as a ternary operation.Rory has 6 pounds of ground beef on hand for making meatballs.

Parking space B covers a greater area.
Here, we are given a parking lot has two types of parking spaces- rectangles and parallelograms, as shown in the figure.
Let us calculate the area of each figure one by one-
Area of rectangle = length × breadth
Here, length = 6 units
breadth = 3 units
Thus, area of rectangle = 6 × 3
= 18 square units
Now, area of a parallelogram = base × height
here, base = 4 units
height = 5 units
Area = 4 × 5
