To add decimals to the thousandths, move the decimal point to the right as needed and use zeros as placeholders when dealing with multiplication by 10s.
Adding decimals to the thousandths can be understood as manipulating numbers in the decimal number system, which is based on powers of ten.
For example, when multiplying 2.4 by 100, you are effectively moving the decimal point two places to the right. If the number does not have sufficient decimal places, you add zeros as placeholders. So, 2.4 becomes 240.
Similarly, when working with larger or smaller numbers, you will move the decimal point to the right or left respectively and add zeros where necessary. For instance, if we are to multiply 45.86 by 100, we move the decimal point two places to the right to get 4586.
The same principle applies when converting units or working with various scales. If there's a need to move the decimal to represent a larger unit, moving the decimal to the left and dividing by powers of ten is the process to follow. The process is reversed when converting to a smaller unit.

The dot plots below show the number of hummingbirds spotted per day at two different feeders. The variability at each feeder is 3.168. The difference between the median number of hummingbirds spotted per day at each feeder is approximately how many times the variability?
Answer:
≈ 3
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
The median number is the middle value of the dot plots
In the feeder 1: 24 24 24 24 26 26 28 28 28 28 28 32 32 34 34 34 34 34 36=> the median number is: 28
In the feeder 2: 10 12 12 12 14 14 16 16 16 16 16 18 18 20 20 20 20 20 20 20 22 22 22 22 22=> the median number is: 18
=> The difference between the median number of hummingbirds spotted per day at each feeder is: 28 -18 =10 and it is = 10 / 3.168
≈ 3 times the variability

1/2 the points are repeated on another question on my page.
Total including this is 40 points. + Brainliest.
Others unanswered 100 points in 3 questions.
Answer:
see below
Step-by-step explanation:
We need to find the diameter of the square
We can find this using the Pythagorean theorem
a^2+b^2 = c^2 where the legs are 7 and 7 and the diameter is c
7^2 +7^2 = c^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
9.899494937 = c
Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.
Since the longest part of the square is less than the diameter of the circle, the square will fit inside the circle without touching
Answer:
Diagonal < Diameter
Step-by-step explanation:
The square will fit inside without touching if the diagonal length is less than the diameter
Diagonal = sqrt(7² + 7²)
7sqrt(2)
Diameter = 11
7sqrt(2) < 11
Because
(7sqrt(2))² < 11²
98 < 121

-16-10.2g = -14.7g + 16.85
a. 147.825
b. -7.3
c. 3.65
d. 7.3
Please select the best answer from the choices provided
Answer:
d. 7.3
Step-by-step explanation:
-16-10.2g = -14.7g + 16.85
4.5g = 32.85
g = 7.3
The solution for the equation -16 - 10.2g = -14.7g + 16.85 is g = 7.3. You can verify it by substituting the solution back into the original equation.
Explanation:To solve the given equation, -16 - 10.2g = -14.7g + 16.85, we must first isolate the variable, g, by moving all terms involving g to one side of the equation and constant terms to the other side. Add 10.2g to both sides of the equation, giving, -16 = -4.5g + 16.85. To further isolate g, subtract 16.85 from both sides resulting in -32.85 = -4.5g. Finally, divide by -4.5 to solve for g. Thus, g = -32.85 / -4.5 = 7.3. We verify our solution by substituting 7.3 back into the original equation and confirming that the equality holds true.

Answer:
45.8
Step-by-step explanation:
We can use the Pythagorean theorem with legs 3x and 4x+7
a^2+ b^2 = c^2
(3x^2) +(4x+7)^2 = c^2
Let x = 8
(3*8)^2 + (4*8+7)^2 = c^2
24^2+ 39^2 = c^2
576+1521 = c^2
2097 = c^2
Take the square root of each side
sqrt(2097) = sqrt(c^2)
45.79301257 =c
Rounding to the nearest tenth
45.8 =c
Answer:
45.8
Step-by-step explanation:
First solve for the other two sides by replacing x with 8
4(8)+7 = 39
3(8) = 24
Then use the pythagorean theorem ([tex]a^{2} + b^{2} = c^{2}[/tex]) to solve for the hypotenuse, c being the hypotenuse
[tex]39^{2} + 24^{2} = c^{2}[/tex]
1521 + 576 = [tex]c^{2}[/tex]
2097 = [tex]c^{2}[/tex]
[tex]\sqrt{2097} = \sqrt{c^{2} }[/tex]

Which angles are pairs of alternate exterior angles? Check all that apply.
4 lines intersect to form 16 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 9; 9, 10, 11, 12; 13, 14, 15, 16.
A: Angle5 and Angle11
B: Angle7 and Angle12
C: Angle11 and Angle16
D: Angle2 and Angle14
E: Angle4 and Angle6
F: Angle8 and Angle10
Answer:
A & E
Step-by-step explanation:
An alternate exterior angle pair would have to be on the outside and be on opposite sides of the same line (like 5 and 11).
Angles 5 and 11, and angles 4 and 6 are pairs of alternate exterior angles.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
Alternate exterior angles are angles that are located on opposite sides of the transversal (a line that intersects two other lines) and outside of the two lines being intersected. They are equal in measure.
Thus, Angles 5 and 11, and angles 4 and 6 are pairs of alternate exterior angles.

Write the word sentence as an inequality. Then solve the inequality. Three less than a number x is more than 15. An inequality that represents this word sentence is..??? Please help me??
Answer:
x-3>15
x>18
Step-by-step explanation:
usually its better to read it from right to left, more than 15 tells you its gonna be >. then you see 3 less than x, which is x-3. Then solve as if the > was an equal sign
x-3>15
+3 +3
x>18
The inequality representing 'Three less than a number x is more than 15' is x - 3 > 15. Solving this, we get x > 18. Hence, x should be greater than 18.
The word sentence given is: 'Three less than a number x is more than 15'. To write this as an inequality, we start by identifying the mathematical phrase for 'Three less than a number x', which is 'x - 3'.
The phrase 'is more than' translates to the inequality symbol '>'.
Therefore, we set up the inequality as follows:
x - 3 > 15
Next, we solve the inequality step-by-step:
Start with the inequality: x - 3 > 15Add 3 to both sides to isolate x: x - 3 + 3 > 15 + 3This simplifies to: x > 18So, the solution to the inequality is x > 18.
In summary, when converting word sentences to inequalities, ensure you accurately translate the phrases and solve them step-by-step to find the solution.
