Answer:
There are six types of triangles based on their side lengths:
Equilateral Triangle: A triangle with all sides of equal length. For example, a triangle with sides of 3cm each is an equilateral triangle.
Isosceles Triangle: A triangle with two sides of equal length. For example, a triangle with sides of 2cm, 2cm, and 3cm is an isosceles triangle.
Scalene Triangle: A triangle with no sides of equal length. For example, a triangle with sides of 2cm, 3cm, and 4cm is a scalene triangle.
Acute Triangle: A triangle with all angles measuring less than 90 degrees. For example, a triangle with angles measuring 60, 75, and 45 degrees is an acute triangle.
Right Triangle: A triangle with one angle measuring exactly 90 degrees. For example, a triangle with angles measuring 45, 45, and 90 degrees is a right triangle.
Obtuse Triangle: A triangle with one angle measuring more than 90 degrees. For example, a triangle with angles measuring 90, 45, and 45 degrees is an obtuse triangle.

Brooklyn divides 2.84 kilograms of fruit salad equally among 4 serving bowls.she wants to know how many kilograms of fruit salad to put in each bowl.she uses the decimal grids shown
By taking a quotient between the mass of salad fruit and the number of bowls, we will see that she needs to put 0.71 kg of salad fruit on each.
How much she needs to put in each bowl?
Here we know that Brooklyn wants to divide 2.84 kilograms of fruit salad equally among 4 serving bowls.
So, to see the mass of fruit salad that she needs to put in each bowl is equal to the quotient between the total mass of frit salad and 4, then we will get:
N = 2.84kg/4
N = 0.71 kg
So she needs to put 0.71 kilograms of salad fruit on each one of the 4 bowls.

Is the square of a sum the same as the sum of squares?
A number's square root multiplied by another number's square root does not always equal the total of these two numbers' square roots.
Why is it called sum of squares?A statistical method called the sum of squares (SS) is used in regression analysis to determine how well the data can fit the model and how dispersed the data are. Since it is determined by adding up the squared differences, the sum of squares is how it is calculated.
A sum's square is equal to the product of its summands' squares and its double products' sums of summands in twos.

Answer:
Y=-[tex]\frac{1}{2}[/tex] + 4
Step-by-step explanation:
You will be using the equation of Y= Mx+B
First you must find the Y intercept, where the line crosses the Y axis, this is at positive four, this will be your B value. then you find the slope by picking 2 easily readable points on the graph, to do this i will choose (0,4) and (2,3), then you find the change in Y and put it in a fraction over the change in x, since this is going down the slope will have a negative infront of it, so your fraction is [tex]\frac{3-4}{2-0}[/tex] which equates to [tex]\frac{-1}{2}[/tex] so your slope is -1/2 (this is M value)
so lastly you plug it all in, Y= -1/2x+4
What is the two steps in solving inequality?
Two steps in solving the inequality: simplify the algebraic expressions by combining like terms and isolating the target variable, then applying the mathematic operators.
Steps in solving the inequality:- Simplify the expression by: open the parentheses of algebraic expression, combine the terms like, and isolate the target variable.
- Use mathematic operators such as: addition, subtraction, multiplication, and division. All mathematic operations must be done on both sides. Addition and subtraction do not change the inequality. Multiplication and division with positive numbers will not change the inequality.
Multiplication and division with negative numbers will change the sign of the inequality.
Example:
Solve the inequality: 3x + 2 < 5x - 8
Step one: Subtract both sides with 5x and 2, this operation does not change the inequality sign
3x + 2 - 5x - 2 < 5x - 8 - 5x - 2
-2x < -10
Step two: Divide both sides with (-2). Since we divide with negative numbers, flip the inequality sign.
-2x/(-2) > -10/(-2)
x > 5
Hence, the solution is x> 5

What is obtuse triangle Class 7?
A obtuse triangle is a triangle in which one of the angles is greater than 90°.
An obtuse triangle can be mathematically defined as a triangle with one angle greater than 90°. The formula for calculating the angles of a triangle is known as the Law of Sines. The formula states that the ratio of the length of a side of the triangle to the sine of its opposite angle is the same for all sides. To calculate the angles of an obtuse triangle, we must first find the ratio of the sides to the opposite angle. For example, if we have a triangle with sides of length a, b and c, then the ratios of the sides to their opposite angles are a/sinA, b/sinB and c/sinC. Once we have found the ratios, we can use the Law of Sines to calculate the angles of the triangle. We can then determine if any of the angles are greater than 90°, which would indicate that the triangle is obtuse.
