the receipt you are using indicate that a mixture should be heated to a temperature of 132F.The mixture is currently at 109F. how many more degrees d does the mixture need to be heated
The mixture must be heated an amount of 23 °F to reach a temperature of 132 °F.
How much must the receipt be heated to be at recommended temperature?
Temperature is the measure of how "hot" a system is. Physically speaking, temperature is closely related to atomic and molecular motion within a system. In this problem we find a mixture that must be at a certain temperature, higher than its real one.
Therefore, the amount required to increase the temperature of the mixture is defined by following subtraction:
ΔT = R - r
Where:
ΔT - Temperature difference, in degrees Fahrenheit.r - Real temperature, in degrees Fahrenheit.R - Expected temperature, in degrees Fahrenheit.If we know that r = 109 °F and R = 132 °F, then the temperature difference is:
ΔT = 132 °F - 109 °F
ΔT = 23 °F

Find the equation of the linear function represented by the table below in slope-intercept form.
x y
1 0
2 2
3 4
4 6
Answer:
y = 2x -2
Step-by-step explanation:
y = mx + b
We need the slope (m) and the y-intercept (b) to write the eqation.
The slope is the change in y over the change in x. We can see from the table that the y is changing by 2 as the x changes by 1
So the slope is 2/1 which is the same as 2
The slope (m) is 2.
The y-intercept is the place where the line crosses the y axis. It is at the point (0,b). When x is zero, what is y? If we follow the patter and move to the number before x is 1, we get x = 0. That means that we have to move back 2 units of the y's. That would be -2. So the y-intercept is the point (0,-2).
The y-intercept (b) is -2
y = 2x - 2
if a^2 = 3a + 1, find the value of (a+1/a)^2
Answer:First, we can simplify the equation a^2 = 3a + 1 by subtracting 3a and 1 from both sides, to get:
a^2 - 3a - 1 = 0
Now we can factor the left side:
(a-1)(a+1) = 0
This equation tells us that either a-1 = 0 or a+1 = 0. So, a = 1 or a = -1.
Next, we can substitute these values into the expression (a+1/a)^2
For a = 1, (1+1/1)^2 = 2^2 = 4
For a = -1, (-1+1/(-1))^2 = 0^2 = 0
So, the value of (a+1/a)^2 is 4 when a = 1, and 0 when a = -1

At the 2006 Winter Olympics in Torino, Italy, US speed skater Apolo Ohno took the gold medal for the 500m sprint by completing the course in 41.935 s. What was his average speed for this event in m/s.
The average speed of Apolo Ohno, in the sprint in the Winter Olympics in 2006, given the time taken to complete the course, was 11. 92 m /s
How to find the average speed ?A body's average speed is the mean value of its speed for a certain time period. The average speed formula is necessary because a moving body's speed vary over time instead than remaining constant. Even though the speed changes, we can still use the total time and total distance numbers, and with the help of the average speed calculation, we can determine a single value that represents the entirety of the motion.
Given the distance that Apolo Ohno had to sprint and the time he completed the course in, his average speed in the event was :

A textbook store sold a combined total of 447 sociology and math textbooks in a week. The number of math textbooks sold was 57 less than the number of sociology textbooks sold. How many textbooks of each type were sold?
If a textbook store sold a combined total of 447 sociology and math textbooks in a week. The number of textbooks of each type that were sold is: 195 Math textbooks, 138 Sociology textbooks.
How to find the number of textbook that were sold?Let x represent the number of math textbooks
Let y represent the number of sociology
Altogether bookseller sold 447 math and sociology textbooks
Hence,
x + y = 447
Since the number of sociology textbooks sold was 57 less than the number of math books sold.
So:
y = x - 57
Substitute for y in the equation
x + y = 447
x + (x - 57) = 447
2x - 57 = 447
Combine like terms
2x = 447 -57
2x = 390
Divide both side by 2x
x = 390/2
x = 195 (Math textbooks)
y = x - 57
y = 195 -57
y = 138 ( Sociology textbooks)
Therefore 195 and 138 textbooks were sold.

The area of the new triangle g’h’i’ is 9.
Describe area of triangle?The area of a triangle is a measure of the size of the triangle, calculated as the amount of space enclosed by its three sides. It can be calculated using the following formula:
Area = (base x height) / 2
where base is the length of one side of the triangle, and height is the perpendicular distance from the base to the opposite vertex.
If a triangle is rotated 180 degrees about the origin, its coordinates will change signs. If it is then dilated by a factor of 3, its coordinates will be multiplied by 3. The new triangle g'h'i' will have the following coordinates: g' (-3,0), h' (0,3), and i' (0,-3).
The height of the new triangle will be the absolute value of the difference between its y-coordinates: h = |3 - (-3)| = 6. The base of the triangle will be the absolute value of the difference between its x-coordinates: b = |-3 - 0| = 3.
Therefore, the area of the new triangle g'h'i' is: A = (1/2)bh = (1/2)(3)(6) = 9.

What is radian and degree?
While a radian is another unit of measurement that is used to measure angles, a degree is a unit of measurement that is used to measure circles, spheres, and angles. The radian, or one pi radian, is only half the diameter of a circle, which has 360 degrees, or its entire area.

The angle in radian is 2.59.
We have to convert this angle into degree.
Since, the formula to convert angle θ from radian to degree is,
Radian = [tex]\frac{180}{\pi }[/tex] degree

What is Slope ?A line's slope, often known as its gradient, is a numerical representation of the line's steepness and direction.
The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Finding the slope between two separate locations and calculating the slope of a line are related tasks.
One approach for determining a line's slope from a graph is to use the formula immediately after knowing the coordinates of two points that are on the line. Let's assume that the coordinate values for the two spots are unknown. Therefore, we also have another way to determine the slope of the line. This approach entails attempting to determine the tangent of the angle formed by the line and the x-axis.
The line is
y = -3x -1
slope is -3 by slope intercept form
The line x = 3y
or y = (1/3)*x
slope is 1/3
we know for a line perpendicular to a given line slope should be -1/m so the slope will be (1/3)
so, x = 3y is perpendicular
y = -3x have slope -3 so it is parallel
y = 3x + 2 slope is 3 so neither
x - 3y = -6
or , y = (1/3)*x + 2 , so slope is (1/3) so perpendicular to line
And
6y = 2x + 10
