HOW do you decide which of two numbers is greater when:
Both numbers are positive
Both numbers are negative
One number is positive and one is negative
2. HOW does a number line help you compare numbers?
3. When you add a positive number and a negative number, how do you determine the sign of the answer?
explanation: any number with a negative sign which is ( - ) is smaller than 0
and a number without a sign next to it is positive
a number line can show you both negative and positive to draw it
for example
__________________
-5 -4 -3 -2 -1 0 1 2 3 4 5
you can see we start from the left with the negative numbers
if you add a positive and a negative sign to get the answer is the biggest number ik negative is always the smallest listen look at it like there is no signs and you see which one is the biggest then take that one

4+(-5)= -1

Which measurements is/are greater than 3 meters 12 feet 3 yards 86 inches key: 1 foot=.305 meters
3ft=1 yard
12=1 foot
Hence, it is \(12\) feet.
What is the yard?
A unit of measurement of length equal to \(3\) feet or approximately \(0.914\)meter.
As per the given information,
\(3\) meters is equals to \(9\) feet, \(3\) yards is equal to \(9\) feet which is equal to \(3\) meters and \(86\) inches is equivalent to \(7\) feet, less than \(9\) feet.
So, \(12\) feet is greater than \(3\) meters.

What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
To find the area painted green, we need to calculate the areas of the square and the triangle and then multiply by 14.2% (or 0.142).
The area of the square is simply the length of one side squared, so:
Area of square = (7 cm)² = 49 cm²
The area of the triangle is one-half the base times the height, so:
Area of triangle = (1/2)(7 cm)(3 cm) = 10.5 cm²
Therefore, the total area of the figure is the sum of the area of the square and the triangle:
Total area = 49 cm² + 10.5 cm² = 59.5 cm²
Finally, to find the area painted green, we multiply the total area by 14.2%:
Area painted green = 0.142 x 59.5 cm² ≈ 8.47 cm²
Therefore,
Approximately 8.47 cm² of the figure is painted green

Consider the following points on the graphs of y = cos(x) and y = cos(x + \pi/6), with the added vertical dashed lines:
Then what are 10c and 10d in that order?
Note that \(\cos a=\frac{4}{5}\). Since \(-\pi<a<0\), [tex)\sin \alpha<0\). So, by the Pythagorean theorem, \(\sin \alpha=-\frac{3}{5}\).
\(c=\cos \left(a+\frac{\pi}{6} \right) \\ \\ c=\cos a \cos \frac{\pi}{6}-\sin a \sin \frac{\pi}{6} \\ \\ c=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}+\frac{3}{5} \cdot \frac{1}{2} \\ \\ c=\frac{4\sqrt{3}+3}{10} \\ \\ \therefore 10c=4\sqrt{3}+3\)
Note that \(\cos b=\frac{4}{5}\) and that \(0<b<\pi\), meaning \(\sin b>0\). So, by the Pythagorean identity, \(\sin b=\frac{3}{5}\).
\(d=\cos \left(b+\frac{\pi}{6} \right) \\ \\ d=\cos b \cos \frac{\pi}{6}-\sin b \sin \frac{\pi}{6} \\ \\ d=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}-\frac{3}{5} \cdot \frac{1}{2} \\ \\ d=\frac{4\sqrt{3}-3}{10} \\ \\ \therefore 10d=4\sqrt{3}-3\)

Compare the expressions using >, < or =
-5 + (-3) and -5- (-3)
Answer:
-5 + (-3) < -5 - (-3)
Step-by-step explanation:
so -5 + (-3) evaluates to -5 - 3 which then evaluates to -8, because you're "going back" on the number line by 3.
-5 - (-3) evaluates to -5 + 3 since the negatives cancel out. this further evaluates to -2. this is greater than the previous value so we use the < (if you put this equation on the right side, since you can technically use > if you put the equation on the left side, just depends on what side you put it on)
-5 + (-3) < -5 - (-3)

The estimate of the square roots and cube roots of numbers can be found by an iterative process;
The Pythagoras's Theorem, PT, and its Converse: Estimating Square Roots
The steps to estimating square roots are;1. The perfect squares that are close to the number for which the square root is sought are listed
Example, to find the square root of 5, we have;
2², 5, 6, 7, 8, 3²
Therefore, the perfect square close to 5 are those of 2 and 3
The number 5 is then divided by the root of the number with closest perfect square, which is √4 = 2
Therefore, we have;
\(\dfrac{5}{2} = 2.5\)The average of the result of the division and the divisor is then found as follows;
\(\dfrac{2 + 2.5}{2} = 2.25\)The required number is then divided again by the average, 2.25, again, to get;
\(\dfrac{5}{2.25} = 2.\overline 2\)The average of the new quotient and the divisor is found again as follows;
\(\dfrac{2.25 + 2.\overline 2}{2} = 2.36\overline 1\)Repeat dividing the required number by the average again as follows;
\(\dfrac{5}{2.36 \overline 1} = 2.23602484472\)The average is found again as 2.23606797792
Dividing 5 gives 2.23606797708
Therefore;
2.236067978 is a good estimate of √5 approximation2. To estimate a cube root of a number, the closest, numbers with a perfect cube are listed
To estimate the cube root of 9, the closest perfect cubes are 8 and 27
We have;
∛8 < ∛9 < ∛27
2 < ∛9 < 3
Given that we have;
The difference between 9 and 8 = 1
The difference between 9 and 27 = 18
Therefore, the cube root of 9, ∛9 ≈ 2
For more accurate value, we have
\({} \hspace {8pt}2.08\\3| \overline {9.000 000}\\ {} \hspace {-3pt} -8\\ {} \hspace {8pt} 1 \ 000 \ 0\)
Where, the 2 in the quotient is given from the closest perfect cube to 9;
2³ = 8 < 9
The 8 is given from 2³ = 8
The 1 is given from 9 - 8 = 1
The 000, is obtained by bringing down 000, from the dividend
Next; Multiply 300 by 2² to get 1,200
1,200 is larger than 1,000, which is the remainder, therefore, a decimal point and 0 is added to the quotient, and a zero is added to the remainder to give 10,000, from which we have;
\(\dfrac{10,000}{300 \times 2^2} = 8\frac{1}{3}\)
The quotient, 8 is added to the quotient line after the zero, to get;
∛9 ≈ 2.08

please help I will give out extra points and give out the brain thing.
Answer:
B; x = 8
Step-by-step explanation:
I think I understand what the picture is saying. So,
On the left hand side, the x's and +1's represent the following expression:
\(2x +5\).
On the right hand side, the x's and -1's represent the following expression:
\(3x -3\).
Put these two together and you get the following equation:
\(2x +5\) = \(3x -3\)
First, Solve for x:
8 = x
So, when solving the equation, x is equal to 8
