Answer: -1/20, or -0.05
Step-by-step explanation:
rewrite -1 1/4 as -5/4
rewrite 0.75 as 75/100 and simplify = 3/4
rewrite 0.45 as 45/100 and simplify = 9/20
-5/4+3/4 = -2/4 = -1/2

The lengths of two sides of a triangle are 8 cm and 10 cm. Identify the range of possible lengths for the third side.
Given that the first two sides of a triangle are 8 cm and 10 cm in length, the third side's range of potential lengths will be [2,18].
What is range?When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself. The difference between the highest and lowest values for a given data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range can also be thought of as the distance between the highest and lowest observation.
Here,
The minimum length can be,
=10-8
=2 cm
The maximum length can be,
=10+8
=18 cm

The width of a claroom i 4meter le than the length. It area i 45cm*45cm. Find the dimenion of the claroom
The dimensions of the classroom are a width is 5 m and a length is 9 m.
We have been given that the width of a classroom is 4m less than the length its area is 45m², then.
L= 4 + W
Area = 45, so
L x W = 45
Now substituting the value of L, we get.
(4+W) W=45,
Now simplifying this we get.
4W + W² =45
W² + 4W - 45 = 0, this is a quadratic equation
Now solving this we get the factors 9 and -5,
(W+9) and (W-5) = 0
Thus, W= -9 or W= 5, since the width cannot be negative,
So, it is width = 5
So, length = 9 m
In physics and arithmetic, the dimension of a mathematical space (or item) is informally defined as the minimal range of coordinates to specify any factor within it. therefore, a line has a dimension of one (1D) due to the fact handiest one coordinate is wanted to specify a factor on it – for instance, the point at 5 on more than a few lines. A floor, together with the boundary of a cylinder or sphere, has a size of two (2d) because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the floor of a sphere. A two-dimensional Euclidean area is a -dimensional area on the aircraft. The internal of a dice, a cylinder, or a sphere is 3-dimensional (3-d) due to the fact 3 coordinates are had to find a factor inside these spaces.
In classical mechanics, area and time are distinct classes and seek advice from absolute space and time. That theory of the sector is a four-dimensional space however not the only one that was discovered as essential to explain electromagnetism. The four dimensions (4D) of spacetime encompass activities that are not really described spatially and temporally, however as a substitute are acknowledged relative to the movement of an observer. Minkowski's area first approximates the universe without gravity; the pseudo-Riemannian manifolds of fashionable relativity describe spacetime with depend and gravity. 10 dimensions are used to describe the superstring principle (6D hyperspace + 4D), eleven dimensions can describe supergravity and M-principle (7D hyperspace + 4D), and the kingdom-space of quantum mechanics is an infinite-dimensional feature area.

Step-by-step explanation:
Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.
Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.
The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.
\text{Function Rule:}
Function Rule:
V(x)=7x
V(x)=7x
Plug x=11 Into Rule:
V(11)=7(11)=77
Correct Answer:
The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.
A function relating these variables is V(x) =V(x)= 7x7x.
So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

the discriminant of a quadratic function is 64 and its vertex is in quadrant III. Identify and explain 3 things you know about the function and /or its graph
Help PLEASE this due tommorow
Answer:
Step-by-step explanation:
If the discriminant of a quadratic function is 64 and its vertex is in quadrant III, here are three things you can know about the function and/or its graph:
The function has two distinct real roots. The discriminant of a quadratic function is the value under the square root in the quadratic formula:
x = (-b +/- √(b^2 - 4ac)) / 2a
If the discriminant is positive, it means that there are two real roots (values of x that make the equation equal to zero). If the discriminant is negative, it means that there are no real roots (the equation has no solutions). If the discriminant is zero, it means that there is only one real root (the equation has one solution). Therefore, if the discriminant is 64, it means that the function has two distinct real roots.
The graph of the function is a parabola that opens downward. The direction in which a parabola opens (upward or downward) is determined by the coefficient of the x^2 term (a). If a is positive, the parabola opens upward. If a is negative, the parabola opens downward. In this case, the vertex of the parabola is in quadrant III.
Find MK
Problem # 37
Please help!
Answer:
17.5
Step-by-step explanation:
Since the triangles are similar, the side lengths are proportional. One way we can solve this is by finding the scale factor for the triangle on the left to the triangle on the right. We can use the two corresponding sides that we know.
Let x = the scale factor
385x = 175 Divide both sides by 385
x = [tex]\frac{175}{385}[/tex] Simplify by dividing the numerator and the denominator by 35
x = [tex]\frac{5}{11}[/tex]
Take the corresponding side of MK and multiply it by [tex]\frac{5}{11}[/tex] to find MK
38.5 x [tex]\frac{5}{11}[/tex] = 17.5

x = 20
Answer:
x = 20°
Step-by-step explanation:
From the picture we know that x + 2x + x + 10 = 90°

What is the order from least to greatest of the following: 0.8, −0.1, 1.1, and −1.5?
Answer:
I think -1.5 -0.1 0.8 1.1
Answer:
-1.5 || -0.1 || 0.8 || 1.1
Explanation:
Since it is from least to greatest, let's compare the 2 negative numbers -1.5 and -0.1.
-1.5 has a 1 in its first place while -0.1 has a 0. This means that -1.5 is smaller because the further a number is on the negative number line the smaller it is.
So, -1.5 is the smallest, then -0.1.
-1.5 || -0.1
Now we compare the 2 positive numbers 0.8 and 1.1.
0.8 has a 0 in its first place and 1.1 has a 1 in its first place. Because the numbers are positive, the number with the biggest digit in in front of the decimal is greater.
So, in this case 1.1 is greater than 0.8.
0.8 || 1.1
In order it is:
-1.5 || -0.1 || 0.8 || 1.1
