The librarian was checking the thicknesses of several books and found that the average thickness of a book was 1.8 centimeters. She found this by averaging the thicknesses of five different books. Four of the thicknesses were 1.4 cm, 1.9 cm, 2.1 cm, and 2.4 cm. What was the thickness of the fifth book that she measured?
Answers
Answer:
1.2 cm
Step-by-step explanation:
1.8 * 5 = 9
9 - (1.4 + 1.9 + 2.1 + 2.4) = 1.2
1.2 + 1.4 + 1.9 + 2.1 + 2.4 = 9

The ratio of side lengths for two similar cubes is į.
Determine the ratios for each of the following. Show your work or explain how you got your answers.
a. the perimeter of one face of the smaller cube compared to the perimeter of one face of the larger
cube
b. the total surface area of the smaller cube compared to the total surface area of the larger cube
c. the volume of the smaller cube compared to the volume of the larger cube
Answers
The ratio of the perimeter of one face for the two cubes is 1/2, the ratio for the total surface area is 1/4, and the ratio for the volume is 1/8.
Explanation:The student wants to find the ratios of the perimeter of one face, the total surface area, and the volume of two similar cubes having side length ratio of 1/2.
Perimeter of one face: Since each face of a cube is a square, the perimeter is 4 times the side length. As the ratio of side lengths is 1/2, the ratio of the perimeters would also be 1/2. This is because perimeter is a one-dimensional measure, therefore the ratio stays proportional to the side length.Total Surface Area: The total surface area of a cube is 6 times the area of one face (a square). Since the area is a two-dimensional measure, it's proportional to the square of the side length ratio, hence the ratio of the surface areas of two similar cubes would be (1/2)² = 1/4.Volume: The volume of a cube is the cube of the side length. Since the volume is a three-dimensional measure, it is proportional to the cube of the side length ratio, so the ratio of the volumes of two similar cubes would be (1/2)³ = 1/8.Learn more about Ratio of Similar Cubes here:

Solve the inequality:
8 + 4x ≥ 12
A. x ≥ 1
B. x ≥ 5
C. x ≤ 5
D. x ≤ 1
Answers
Answer:
x ≥ 1
Step-by-step explanation:
8 + 4x ≥ 12
Subtract 8 from each side
8-8 + 4x ≥ 12-8
4x ≥ 4
Divide by 4
4x/4 ≥ 4/4
x ≥ 1
The solution to the inequality 8 + 4x ≥ 12 is x ≥ 1. Therefore, the correct answer is A. x ≥ 1.
Correct option is A.
To solve the inequality 8 + 4x ≥ 12, we need to isolate x. Here's how we do it step by step:Start with the given inequality: 8 + 4x ≥ 12.First, subtract 8 from both sides of the inequality to isolate the term with the variable:8 + 4x - 8 ≥ 12 - 8.Simplify both sides:4x ≥ 4.Now, divide both sides by 4 to solve for x:(4x)/4 ≥ 4/4,x ≥ 1.So, the solution to the inequality is:x ≥ 1.Now, let's match this solution to the given answer choices:A. x ≥ 1 - This matches our solution.B. x ≥ 5 - This is not correct.C. x ≤ 5 - This is not correct.D. x ≤ 1 - This is not correct.The correct answer is A. x ≥ 1.For more questions on inequality -

x = 3y + 1
y =
X=
Answers
Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1

What is in an ellipse?An ellipse is a curve formed by a plane, that intersects a cone at an angle with respect to the base. It is a curve surrounded by two focal points. Ellipse is a locus of points, the sum of whose distances from two foci is constant.
What is an ellipse shape?An ellipse is a circle that has been stretched in one direction, to give it the shape of an ova
What is an ellipse example?An ellipse has an eccentricity less than one, and it represents the locus of points, the sum of whose distances from the two foci of the ellipse is a constant value. A simple example of the ellipse in our daily life is the shape of an egg in a two-dimensional form and the running tracking in a sports stadium.
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity
An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution.
what is the general formula of ellipse ?The standard equation for an ellipse, x 2 / a 2 + y2 / b 2 = 1, represents an ellipse centered at the origin and with axes lying along the coordinate axes. In general, an ellipse may be centered at any point, or have axes not parallel to the coordinate axes.

Harry bought a used dirt bike for $1,050. Before purchasing the bike, Harry had a total of
$2,250 in his savings account. What percentage of his savings account did Harry spend on
the dirt bike?
Answers
Answer:
. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Step-by-step explanation:
Final answer:
Harry spent 46.67% of his savings on the dirt bike, calculated by dividing the price of the dirt bike by the amount in his savings account and then multiplying by 100.
Explanation:
The question is asking how to calculate the percentage of Harry's savings that was spent on a dirt bike. To find the percentage, you would divide the amount spent on the dirt bike by the total amount in the savings account and then multiply by 100. Harry spent $1,050 on the dirt bike and had $2,250 in his savings account originally.
Here's the step-by-step calculation:
Divide the cost of the dirt bike by the total savings: $1,050 / $2,250.You get a decimal result from step one, which you then multiply by 100 to get a percentage.The calculation is ( $1,050 / $2,250 ) × 100 = 46.67%.Therefore, Harry spent approximately 46.67% of his savings on the dirt bike.

(–6, –12)
(–12, 12)
Answers
Answer:
The system of equations as described:
y = (-3/4)x + 3
y = -12
Combining two equations, we have:
=> -12 = (-3/4)x + 3
=> -15 = (-3/4)x
=> x = -15 x (-4/3) = 20
=> Solution is (20, -12)
=> Option A is correct.
Hope this helps!
:)
Step By Step:
The equations given to us are:
y = (-3/4)x + 3
y = -12
Now that we have y we can change that to -12
-12 = (-3/4)x + 3
-15 = (-3/4)x
x = -15 x (-4/3) = 20
This would give us (20, -12)
