Answer:
0.02 repeating
Step-by-step explanation:
So first we do 2/9 since all the operations are division we solve left to right. We get 0.2 repeating. Then, after that whenever we divide by 10, we shift everything to the right so we end up with :
0.02 repeating.

Answer:
y ≥ 3x
Possible solution: x=1, y=3
Step-by-step explanation:
Since Henry has atleast 3 times as much money as Deb
y=3x
y must always be greater than or equal to 3x

HOW TO OPEN BRACKET?In a mathematics, algebraic expressions can be in bracket. This bracket means we multiply all the variables outside by those inside.
According to this question, we are given the following expression: 2x(x-4)
This means that 2x multiples x and -4 independently.
That is; 2x × x and 2x × -4
2x² - 8x
Therefore, the product of 2x(x-4) is 2x² - 8x.

How are algebra tiles named?
We name the Algebra Tile pieces by considering the area of each, meaning we need to know the dimensions of each piece. If the small yellow square has a length of 1 unit, the area of the small square is 1 square unit. Then the long green rectangle has dimensions 1 by x and has an area of x square units.
What are algebra tiles examples?
Algebra tiles are square and rectangle-shaped tiles or tiles that represent numbers and variables. For example, we can use square tiles to represent numbers. Each square tile is equal to one. So, four can be represented by four square tiles.

What is the solution to the system graphed below?
Answer: (-4, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.
The two lines intersect in quadrant III
where x and y are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 4 and down 1 so that's (-4, -1).
So the solution to this system is (-4, -1).

Which value for x will make 3x + 10 > 75 correct?
Answer:
The answer is D
Step-by-step explanation:
I subtracted 10 from 75 and got 65 then divided 65 by 3 and got 21
The answer is c.
An inequality solution is any value of the variable that makes the inequality true. Solving linear inequalities is almost exactly like solving linear equations.
How to find which value for x will make 3x + 10 > 75 correct?
Subtract 10 from both sides we get , 3x+ 10 - 10 = 75 - 10
3x + 0 > 65
divide both sides by 3 implies
3x / 3 = 65 /3
=> x > 15.
Thus Option c is correct.

V = 1815.8 mm^3
Step-by-step explanation:
Okay so this is a tricky one, thats why i decided to help. The first thing you need to do is find the volume of the hemisphere, the formula to do this is 2TTr3 / 3. when you input the values, solve, and round to the nearest tenth you get approximately 718.4 mm^3. The next step is to find the volume of the cone, the formula for volume of a cone is πr^2h/3. When you input the values, solve, and round to the nearest tenth you get approximately 2534.2 mm^3. The third and final step is to subtract the volume of the hemisphere from the volume of the cone, and when you do that you get V = 1815.8 mm^3.

Two histograms showing the number of pets owned by boys and girls in a science class are each skewed left. Which measure of variability should be used to describe the data? mean median standard deviation interquartile range
Answer: D : interquartile range
Step-by-step explanation: I just took the test
The measure of variability which should be used in this case interquartile range. so option D is correct.
What is quartile ?A quartile is a type of quantile that divides a data set into four equal parts, or quarters. The first quartile (Q1) marks the 25th percentile of the data, the second quartile (Q2) marks the 50th percentile, or median, of the data, and the third quartile (Q3) marks the 75th percentile of the data. These quartiles divide the data into four equal parts and provide information about the distribution of the data and its spread. The interquartile range (IQR), which is the difference between Q3 and Q1, is a measure of the spread of the middle 50% of the data.
When the data is skewed, the mean can be misleading as it is affected by the skewness of the data. In such cases, the median is a better measure of central tendency that represents the typical value of the data.
Therefore, the measure of variability that should be used to describe the data in this case is the interquartile range (IQR). IQR is a measure of spread that is not affected by extreme values or outliers and is often used with skewed data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data.
So, the answer is the interquartile range.

Rosalia went on a long bike ride. The table shows how long she biked and the distance she traveled. Determine whether the relationship between hours biked and miles traveled is proportional.
Answer:
There needs to be a graph.
Step-by-step explanation:
The rate of change is not the same for all the cases so, the relationship between hours biked, and the miles traveled is not proportional.
What is proportionality?We use constant of proportionality in mathematics to calculate the rate of change and at the same time determine if it is direct variation or inverse variation that we are dealing with.
From the table, we need to find the rate of change between two given hours and the miles traveled at that time.
Now,
Between 1 hour and 2 hours.
The rate of change.
= (26 - 12) / (2 -1)
= 14 / 1
= 14
Between 2 hours and 3 hours.
The rate of change.
= (30 - 26) / (3 - 2)
= 4 / 1
= 4
Between 3 hours and 4 hours.
The rate of change.
= (48 - 30) / (4 - 3)
= 18 / 1
= 18
Since,
The rate of change is not the same for all the cases so,
Hence, the relationship between hours biked, and the miles traveled is not proportional.

The angle 01 is located in Quadrant III, and cos(01) = -30/13
What is the value of sin(01)
Answer:
sin(01) = -32.70/13Step-by-step explanation:
Given cos(01) = -30/13 where angle 01 is located in quadrant III. In the third quadrant, both cos and sin are negative. only tan is positive.
To calculate sin(01), we will apply the trigonometry expression as shown below;
cos(01) = -30/13
According to SOH CAH TOA;
cos(01) = adjacent/hypotenuse = -30/13
sin(01) = opposite/ hypotenuse
To get the hypotenuse, we will use the pythagoras theorem
[tex]hyp^{2}=opp^{2}+adj^{2} \\opp^{2}= hyp^{2}-adj^{2}\\opp^{2}= 13^{2} -(-30^{2} )\\opp^{2} = 169+900\\opp^{2}=1069\\opp = \sqrt{1069} \\opp = 32.70\\[/tex]
sin(01) = 32.70/13
Since sin is also negaitve in the third quadrant, the value of
sin(01) = -32.70/13
[tex]01 = cos^{-1}- 30/13[/tex]
