A percent is a unit of measurement used to express a ratio as part of 100. It is often used to express a proportion of a whole quantity.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
When a part of a whole is represented as a percent, it means that it is expressed as a fraction of 100.
For example, if a quantity is represented as 50%, it means that it is equal to 50/100 or 1/2 of the whole.
Therefore, part of a whole is represented by a percent that is a fraction of 100, with the numerator representing the part and the denominator representing the whole. The value of the fraction is then multiplied by 100 to express the ratio as a percentage.

A mouse has made holes in opposite corners of a rectangular kitchen. The width of the kitchen is 3 meters and the distance between the mouse's holes is 5 meters. What is the length of the kitchen?
The length of the kitchen given the width and distance between the mouse's holes is 4 meters.
What is the length of the kitchen?The width of the kitchen and the two holes in opposite corners of the rectangular kitchen forms a right angle triangle.
The two holes in opposite corners of the kitchen is therefore the hypotenuse.
Distance between the mouse's holes = 5 meters
Width of the kitchen = 3 meters
Hypotenuse² = opposite² + adjacent²
5² = 3² + x²
25 = 9 + x²
25 - 9 = x²
16 = x²
find the square root of both sides
x = √16
x = 4 meters

600 dollars
Sandra has 600 dollars now. The solution is obtained using arithmetic operations.
What are arithmetic operations?
There are four basic operations which are listed as follows:
Addition(‘+’): This operation deals with finding the sum.Subtraction(‘-’): This operation deals with finding the difference. Multiplication(‘×’): This operation deals with finding the product.Division(‘÷’): This operation deals with finding the quotient.We are given that when Sandra was 8 years old she had 100 dollars in the bank and each year for her birthday she deposited 25 dollars in the same account.
This means that Sandra has deposited 25 dollars every year for 20 years because we are provided that she had 100 dollars when she was 8 years and now she is 28 years. So, she has deposited the amount for 20 years.
So, the total money she deposited= 25*20=500 dollars
Also, she had 100 dollars when she was 8 years.
Thus, the total money she has= 500+100= 600 dollars
Hence, Sandra has 600 dollars in the account now.

How do you find the distance between two points in 8th grade?
To calculate the distance between two places, we can apply the distance formula d=((x2 - x1)² + (y2 - y1)²).
What is the distance?The distance of an object is its overall motion, regardless of direction.
Distance is the amount of space that an object has covered, regardless of where it began or concluded.
By understanding how far an object is from us, we may calculate its actual size.
It is possible to calculate the area that an object takes up in the sky.
The actual size of an object can then be determined by taking into account its distance.
The further away something is, the smaller it appears.
The distance between two locations on a plane is the length of the line segment connecting them.
The formula d=((x2 - x1)² + (y2 - y1)²) is frequently used to calculate the separation between two points.
Therefore, to calculate the distance between two places, we can apply the distance formula d=((x2 - x1)² + (y2 - y1)²).

If you were given sticks of the following lengths, how many triangles can you make?

I know you can make a triangle but would it be infinite triangles or just one?
Please answer fast I need help
The correct answer is C. Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.
When a diagonal is drawn in a rhombus, it splits the rhombus into two congruent triangles. Since the diagonal bisects the rhombus, the two triangles are mirror images of each other.
In a rhombus, opposite sides are parallel and equal in length, which means that the two sides of the triangle that are formed by the diagonal are congruent. Therefore, each triangle is isosceles.
A rhombus is a quadrilateral with four equal sides, so we know that the triangles have two equal sides, but we cannot say anything about the other sides and angles, so we cannot say that it is acute, equilateral or obtuse.
Answer:
The correct answer is C. Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.
A rhombus is a quadrilateral with all four sides equal in length. When a diagonal is drawn in a rhombus, it forms two congruent triangles. Since the rhombus has four equal sides, each triangle will have two equal sides. In other words, the two triangles are isosceles triangles.
Option A is incorrect, because a rhombus does not always have 2 acute angles. A rhombus can have acute, right or obtuse angles, and the angles of the rhombus are not related with the triangles formed by drawing a diagonal.
Option B is incorrect, because a rhombus does not always have 4 equal angles. A rhombus can have acute, right or obtuse angles, and the angles of the rhombus are not related with the triangles formed by drawing a diagonal.
Option D is incorrect, because a rhombus does not always have 2 obtuse angles. A rhombus can have acute, right or obtuse angles, and the angles of the rhombus are not related with the triangles formed by drawing a diagonal.

The largest total number of balls that alice could have in the bag is 5.
Bob wants to pick five balls from the bag and get at least one of each color, red and blue. Alice has guaranteed that this is possible, which means that there must be enough balls in the bag and at least one of each color.
The maximum number of balls in the bag can be achieved when the total number of balls is the same as the total number of balls Bob picks, which is 5.
In this case, Bob could pick one red and four blue, or one blue and four red, and he would still get at least one of each color.
This means that the largest total number of balls that Alice could have in the bag is 5.
It's important to note that this is the maximum number and it's possible that there are less balls in the bag. The maximum number of balls in the bag can only be achieved when Bob picks one red and four blue, or one blue and four red.

which of the following can be a form of solution of 3x+0y+7=0 in two variables? i)-7/3,m ii) m,-7/3 iii) -7/3,0
If y=x+7 will be the value of the function that crosses the y-axis at position (0, 7).nThe replacement approach refers to determining any variable's value from one equation in terms of another variable. The correct answer is c. -7/3,0
Considering that, the point where the function crosses = (0, 7) Considering that the function's intersection point is now = (0, 7).As a result, the point must fulfil the function.
We have to check whether these pairs satisfy equation 3x+0y+7=0 or not.
So, we will put these pairs one by one.
A) (-7/3,m) x=-7/3 & y=m
Than
3×(-7/3)+0×m+7=0
-7+0+7=0
0=0 so, it satisfies.
B) (m, -7/3) x=m & y=-7/3
Than
3×m+0×-7/3+7=0
3m+0+7=0
3m+7 =0 so, it does not satisfies.
D) (-7/3,0) x=-7/3 & y= 0
Than
3x(-7/3)+0×0+7= 0
-7+7= 0
0=0 so, it satisfies.

The relationship between attending your classes and passing your classes would best be described as:
Causal
Correlation
Spurious Correlation
No relationship
It will be best defined as a spurious correlation rather a casual correlation.
What is a spurious correlation?
A spurious correlation occurs when two variables are correlated but don’t have a causal relationship. In other words, it appears like values of one variable cause changes in the other variable, but that’s not actually happening.
If you look up the definition of spurious, you’ll see explanations about something being fake or having a deceitful nature. It has the outward appearance of genuineness, but it’s an imitation. With this definition in mind, spurious correlations look like causal relationships in both their statistical measures and in graphs, but it’s not real.
For example, ice cream sales and shark attacks correlate positively at a beach. As ice cream sales increase, there are more shark attacks. However, common sense tells us that ice cream sales do not cause shark attacks. Hence, it’s a spurious correlation.
Now,
As attending classes is not related to passing the class because one can pass an examination without attending classes.

Given that Justin is collecting data on reaction time, what type of data is he working with?
Select the correct answer below:
A. qualitative
B. discrete quantitative
C. continuous quantitative
D. none of the above
Since reaction time is measured and not constrained to a specific range of numbers, it is continuous quantitative data.
'What is continuous quantitative?'
A continuous data set is a quantitative data set that represents a scale of measurement that includes fractions and decimals in addition to whole integers. Values like height, weight, length, temperature, and other similar metrics would be included in continuous data sets. They are items that can be quantified in decimals and fractions. A continuous data set typically requires the use of a tool, such as a ruler, measuring tape, scale, or thermometer, to create the numbers.

Please help!! circular flower bed is 20 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in square meters.
The area of the sidewalk is 144π square meters.
Describe area of a circle?The area of a circle is a measure of the amount of space inside the circle. It is defined as the product of Pi (π) and the square of the radius of the circle.
A = π × r²
The radius is the distance from the center of the circle to its edge. The area of a circle is a scalar quantity and is typically expressed in square units, such as square centimeters or square meters.
The diameter of the circular flower bed is 20 m, so its radius is 20/2 = 10 m.
The sidewalk around the flower bed is 2 m wide, so the radius of the circular sidewalk is 10 + 2 = 12 m.
The area of a circle can be found using the formula:
A = πr^2
So the area of the circular sidewalk is:
A = π × 12²= π × 144 = 144π m²
Therefore, the area of the sidewalk is 144π square meters.

What is the distance between the points 2 0 and (- 2 0?
16 units are the distance between the two points (2, 0) and (-2, 0).
What is the distance?An object's distance is determined by its total velocity, regardless of direction.
Regardless of where it started or ended, distance is the amount of space that an object has covered.
We can determine an object's true size by knowing how far it is from us.
Usually, the formula shown below is used to calculate the separation between two points: d=((x2 - x1)2 + (y2 - y1)2)
So, the distance formula is:
d=((x2 - x1)2 + (y2 - y1)2)
Points are: (2, 0) and (-2, 0)
Now, enter the numbers in the formula above and do the following calculation:
d=((x2 - x1)2 + (y2 - y1)2)
d=(-2 - 2)2 + (0 - 0)2)
d=(-4)²
d=16
Therefore, 16 units are the distance between the two points (2, 0) and (-2, 0).
