what is half of 220?
Answer:110
Step-by-step explanation: just divide by 2 to find out half.
110 is half of 220.
Here, we have,
To find half of a number, you divide it by 2.
In this case, to find half of 220, you divide 220 by 2:
220 ÷ 2 = 110
Therefore, half of 220 is 110.
When we divide 220 by 2,
we are splitting it into two equal parts, with each part being 110.
so, we get,

The region of integration in the xy-plane for the given integral ∫∫R √(4xy) dy dx, where R is the region bounded by x = 0, x = -3, y = 0, and y = -9 - x^2, can be visualized as a triangular region in the first quadrant.
What is the geometric representation of the given integral?The given integral is a double integral of the function √(4xy) over a specific region in the xy-plane. To determine the region of integration, we consider the given bounds: x ranges from 0 to -3, and y ranges from 0 to -9 - x^2.
Starting with the x bounds, x = 0 represents the y-axis, while x = -3 represents a vertical line passing through the point (-3, 0). Thus, the region is bounded by the y-axis on the left and the vertical line x = -3 on the right.
Moving on to the y bounds, y = 0 represents the x-axis, while y = -9 - x^2 represents a downward-opening parabola with its vertex at the origin and its axis of symmetry parallel to the y-axis. Since y is negative, the parabola lies below the x-axis.
By combining the x and y bounds, we obtain a triangular region in the first quadrant. The triangle is formed by the x-axis, the line x = -3, and the curve y = -9 - x^2. This region of integration represents the area over which the function √(4xy) is being integrated.

A glass ball is packed in the box shown. Which expression represents the volume of foam padding needed to fill the space in the box around the sphere in terms of Pi
Answer: (27- 4/3 pi) r^3
Step-by-step explanation: 1. Volume of a cube: V= a^3, V= 3^3 , V=27
2. Volume of a sphere: V=4/3 pi r^3 ......
The expression which represents the volume of the foam padding needed to fill the space in the box around the sphere in terms of π is option C. (27 - [tex]\frac{4}{3}[/tex] π) r³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
We have a sphere of radius r inside a cube of side length 3r.
Volume of a cube = (a)³, where a is the side length.
Here a = 3r
Volume of the cube = (3r)³ = 27r³
Volume of a sphere of radius r = [tex]\frac{4}{3}[/tex] π r³
Volume of the foam padding needed to fill the space in the box around the sphere = 27r³ - [tex]\frac{4}{3}[/tex] π r³
= r³ (27 - [tex]\frac{4}{3}[/tex] π)
Hence the volume of the space inside the cube outside the sphere is r³ (27 - [tex]\frac{4}{3}[/tex] π).

The function g(n) = n2 − 16n + 69 represents a parabola.
Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points)
Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)
Part C: Determine the axis of symmetry for g(n). (2 points)
Answer:
Step-by-step explanation:
A) y + ? = n^2 - 16n + ? + 69
y + 64 = n^2 -16n + 64 + 69
y + 64 = (n-8)^2 + 69
y = (n-8)^2 + 5
B) vertex is (8,5) because the value of a vertex is always (h,k) from the parent vertex function:
y = a(x-h) + k
it's a minimum only because the (a) value is positive
C) axis of symmetry = 8

PLEASE HELP!! Using the SAS Congruence Theorem
Answer:
LAST ONE IS angle JLK congruent to angle LNM, SAS
Step-by-step explanation:
The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
The triangles JLK and LMN are similar triangles.
Which means the sides are proportional and those angles are congruent.
We have to prove that JLK is similar to LMN.
By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

julio distributed a survey to his fellow students asking them how many hours they spent playing sports in the past day. He also asked them to rate their mood on a scale from 0 to 10, with 10 being the happiest. Julio created the following scatterplot and regression line to show this relationship. The fitted line has a y-intercept of 5. What is the best interpretation of this y-intercept?
Answer: The model indicates that students who have spent 0 hours playing sports will have an average mood rating of 5
Step-by-step explanation:
A y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.
What is linear regression?Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables.
In this case, y is the rating of the mood on a scale from 0 to 10 while the x represents the number of hours in playing sports.
We know the y-intercept means the x-coordinate is 0 means the number of hours spent playing sports is 0.
So, a y-intercept of 5 means students who have spent 0 hours playing sports will have an average mood rating of 5.
Hence, a y-intercept of 5 means players spending 0 hours playing sports will have an average rating of 5.
