A stack of paper contains 400 sheets. The volume of the stack is 140.25 cubic inches. Each sheet of paper is identical, with a length of 11 inches and a width of 8.5 inches. Find the height of each sheet of paper. Please put the process.
Answer:
[tex]0.00375\ \text{inches}[/tex]
Step-by-step explanation:
Volume of the stack of paper is 140.25 cubic inches
The length and width of the stack will be equal to that of a single sheet of paper so
[tex]l=11\ \text{inches}[/tex]
[tex]w=8.5\ \text{inches}[/tex]
Let [tex]h[/tex] be the height of the stack.
Volume of the stack would be
[tex]lwh=140.25\\\Rightarrow h=\dfrac{140.25}{lw}\\\Rightarrow h=\dfrac{140.25}{11\times 8.5}\\\Rightarrow h=1.5\ \text{inches}[/tex]
So the stack has a height of 1.5 inches. Now there are 400 sheet of paper in the stack.
Thickness of one sheet of paper is given by
[tex]\dfrac{1.5}{400}=0.00375\ \text{inches}[/tex]
Hence, the height of each sheet of paper is [tex]0.00375\ \text{inches}[/tex].

Jaxon’s mother spends more than 2 hours cleaning the house. The inequality x greater-than 2 represents the situation. Which graph represents the inequality?
A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the right of the circle is shaded.
A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the left of the circle is shaded.
A number line going from negative 3 to positive 7. A closed circle is at 2. Everything to the right of the circle is shaded.
A number line going from negative 3 to positive 7. A closed circle is at 2. Everything to the left of the circle is shaded.
Answer:
A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the right of the circle is shaded.
Step-by-step explanation:
x > 2 is the inequality
It is open circle at 2 as 2 is not included. Shaded to the right of the circle as it should be greater than 2
------------------
A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the right of the circle is shaded.
Yes, this is the correct option
A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the left of the circle is shaded.
No, it should be right not left
A number line going from negative 3 to positive 7. A closed circle is at 2. Everything to the right of the circle is shaded.
No, it should be open circle as 2 is not included
A number line going from negative 3 to positive 7. A closed circle is at 2. Everything to the left of the circle is shaded.
No, it should be open circle and right side to be shaded, not left
Step-by-step explanation:
The correct graph that represents the inequality "x > 2" is:
a) A number line going from negative 3 to positive 7. An open circle is at 2. Everything to the right of the circle is shaded.
In the inequality "x > 2," the symbol ">" represents "greater than." This means that we are looking for values of x that are greater than 2.
On a number line, we can represent all the possible values of x. The number line given in option a) ranges from negative 3 to positive 7, covering a range of values.
To represent the condition that x is greater than 2, we need to place a circle on the number line at the value 2.
Since the inequality is strict ("x > 2"), we use an open circle at 2.
An open circle indicates that the point 2 itself is not included in the solution.
Finally, everything to the right of the open circle should be shaded to indicate that any value greater than 2 is a solution to the inequality.
This shading represents all the values of x that satisfy the inequality "x > 2."
Therefore, option a) is the correct graph that represents the inequality "x > 2."

A rectangular playground is 28m long and 15m wide. If all sides are
extended lm outward, what is the area of the enlarged playground ?
Answer:
464m^2
Step-by-step explanation:
Given data
Dimension of the regular playground
Length= 28m
Width= 15 m
We want to extend both sides by 1 m
Length= 28+1= 29m
Width= 15+1= 16m
Hence the area
Area=Length*Width
Area= 29*16
Area= 464m^2
The Area is 464m^2

Carlo puts tins into small boxes and into large boxes. He puts 6 tins into each small box. He puts 20 tins into each large box. Carlo puts a total of 3000 tins into the boxes so that number of tins in small boxes : number of tins in large boxes = 2:3 Carlo says that less than 30% of the boxes filled with tins are large boxes. Is Carlo correct? You must show all your working.
Answer: Carlo is incorrect
Step-by-step explanation:
3000/(2+3) = 600 (each ratio)
2:3 = 2(600):3(600) = 1200:1800
1200/6 = 200 small boxes
1800/20 = 90 large boxes
290 boxes altogether (large and small)
(large boxes/boxes altogether)x100
(90/290)x100 = 31%
31%>30%
Therefore Carlo is incorrect

XYZ is a triangle in which XY = 11 centimeters and YZ = 15 centimeters. The length of XZ is in whole centimeters and is greater than 20 centimeters. What are the possible lengths of XZ?
Answer:
Possible lengths of [tex]XZ[/tex] are [tex]21\,\,cm,22\,\,cm,23\,\,cm,24\,\,cm,25\,\,cm[/tex]

A rectangle’s length is three times its width, w. Its area is 243 square units. Which equation can be used to find the width of the rectangle?
w2 = 3(243)
3w2 = 243
4w2 = 243
3w2 = 3(243)
Answer:
3w² = 243

The measure of one interior angle of a parallelogram is 50 degrees more than 4 times the measure of another angle
The measure of the smaller interior angle is
and the measure of the larger interior angle is?
Answer:
smaller ∡ = 26°
larger ∡ = 154°
Step-by-step explanation:
opposite angles are congruent
adjacent angles are supplementary
in this problem, the angles are supplementary
'x' = measure of smaller angle
x + 50 + 4x = 180
5x = 130
x = 26
The given information and the relationship between the angles of a
parallelogram can be used to find the interior angles.
The measure of the smaller angle is 26°The measure of the larger angle is 154°Reasons:
A property of a parallelogram is that the diagonally opposite angles are
equal, and the adjacent angles are supplementary.
Therefore, two of the four interior angles of a parallelogram are equal.
Let x and y represent the two angles of different measure in the
parallelogram
y = 4·x + 50°
y + x = 180°
Which gives;
y = 180° - x
Therefore;
180° - x = 4·x + 50°
180° - 50° = 4·x + x
130° = 5·x
x = 130° ÷ 5 = 26°
x = 26°y = 4 × 26° + 50° = 154°
y = 154°Therefore;
The measure of the smaller interior angle, x = 26°The measure of the larger interior angle, y = 154°Learn more about the properties of a parallelogram here:
