Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs 30 kilograms, and the table with 8 boxes on top weighs a total of 310 kilograms.
The total weight W of the barricade in kilograms is a function of x, the number of boxes Rei stacks on the table.
Write the function's formula.
W, equals
Answer: The answer is W=70+30x
Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.
The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.
Therefore, the weight of the table without boxes is 70 kilograms.
Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -
So, if 'g' denotes the weight of the table alone, then we have,

Answer:
[tex] {eb}^{2} = {ab}^{2} + {ea}^{2} \\ {ab}^{2} = {eb}^{2} - {ea}^{2} \\ {ab}^{2} = {20}^{2} - {12}^{2} \\ ab = 16 \\ \\ {db}^{2} = {bc}^{2} + {dc}^{2} \\ {bc}^{2} = {db}^{2} - {dc}^{2} \\ {bc}^{2} = {20}^{2} - {16}^{2} \\ bc = 12 \\ \\ so \: ac = ab + bc \\ ac = 28[/tex]

58.4 degrees
b.
62.3 degrees
c.

Please select the best answer from the choices provided
The sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees
What is a regression model?A regression model is used to determine the association and correlation between two variables
Using a graphing calculator, the sine regression model of the dataset is:
[tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex]
To calculate y(30), we substitute 30 for x in the equation.
So, we have:
[tex]y =20.077 \sin(0.500 * 30- 1.959) + 67.577[/tex]
Evaluate the product
[tex]y =20.077 \sin(15- 1.959) + 67.577[/tex]
Evaluate the difference
[tex]y =20.077 \sin(13.041) + 67.577[/tex]
Evaluate the sine value
[tex]y =20.077 *0.4570+ 67.577[/tex]
Evaluate the product
[tex]y =9.1752+ 67.577[/tex]
Evaluate the sum
[tex]y =76.7522[/tex]
Approximate
[tex]y \approx 76.8[/tex]
Hence, the sine regression model is [tex]y =20.077 \sin(0.500x- 1.959) + 67.577[/tex], and the value of y(30) is 76.8 degrees

Answer:
18.38Explanation:
since this triangle is a right-angled triangle and one its angles equals 45° then it's an isosceles right triangle which means that the side opposite 45° (the side to the left) is equal to 13 too.
so according to pythagoras theorem c = √(a²+b²)
x =√(13²+13²)
x = √(169+169)
x = √338
x ≈ 18.38
note: in the question it's mentioned to find y! and I believe it is just an error! it's about to find x and that's more resonable!
The dot plot shows the favorite sport to play according to some middle school students chosen at random. Which statement is true according to the information in the dot plot ?
What are the options?
Answer:
B: More than 25% of the students chose football and tennis as their favorite sport to play.
Step-by-step explanation: You need to find the total, which is 50. Since it says more than 25 percent of the students chose football and tennis your answer will need to be more then 25 percent. You add football plus tennis (10+3=13). Now you set up your proportion- 50 as your whole/total, 13 as your part, and substitute you percent with a variable like (p), then 100. Cross multiply. I did a shortcut which replaces the Ice Ice Baby process, so multiply 13x100= 1300, then your product divide it by 50 ( total) 1300/50= 26. This makes the statement true.

10) What changes when a figure is
transformed by a reflection, rotation,
or a translation?
A) its area
C) its position
B) its size
D) its perimeter
Answer:
size because when a figure is squeezed, it shrinks and changes the size
Answer:
Its Position
Step-by-step explanation:
Reflection-when the shape is reflected over an axis
Rotation-when the shape is rotated around a singular point
Translation-when the shape is moved up/down or left/right
None of these change any part of the shape it just moves the shape around. :)

Answer:
( x + 2 )² + ( y - 6 )² = 49
Step-by-step explanation:
→ Write the form of an equation of a circle
( x - a )² + ( y - b )² = r²
→ Substitute in the centre remembering to switch the signs
( x + 2 )² + ( y - 6 )² = r²
→ Substitute in radius
( x + 2 )² + ( y - 6 )² = 49
