Answer:
2.01 x 15 = 30.15
Step-by-step explanation:
2.01 x 15 = 30.15
or
201 * .15 = 30.15
Answer:
201 changes to 2.01 or 15 changes to 0.15
2.01 · 15 = 30.15
201 · 0.15 = 30.15
Step-by-step explanation:
Since 201 · 15 = 3015, and we want 30.15
We move the decimal two place to the left.
Since we did this on one side of the equation, we must do it on the other as well.
201 becomes 2.01. You could also change 15
15 becomes 0.15
What is an equation of the line that passes through the points (-4, -1) and (6, -1)
Answer:
y = -1
Step-by-step explanation:
In a sense this is a trick question. Notice that the y-coordinates of these two points are the same: -1. That tells us that the line is a horizontal one with equation y = -1. Nothing further to do here.
Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away from the hook.
The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.
Answer:
Kindly check explanation
Step-by-step explanation:
If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.
Hypotenus² = opposite² + adjacent²
(refer to attached picture)
x² = 6² + 8²
x² = 36 +. 64
x² = 100
x = sqrt(100)
x = 10 meters
You can use the actual depth value to obtain the actual solution to your question.
What is the y-intercept of y= -3x + 6

Andrea has 3 tiles.
One is a regular octagon, one is a regular pentagon and one is a regular pentagon.
Andrea thinks 3 tiles will fit together perfectly.
Show calculations to show that she is wrong.
Step-by-step explanation:
We are going to start by working out the interior angles so first of all to work out the interior angle we used the formula: num of sides - 2 * 180 for the sum of degrees in a shape.
Lets test this formula.
Lets say we have a square it has 4 sides 4-2 = 2 *180 = 360 this is correct,meaning we can trust this formula.
Now lets put it to use.
Octagon has 8 sides - 2 = 6.
6 * 180 = 1080
Pentagon has 5 sides - 2 = 3
3 * 180 = 540
Another Pentagon 5 sides - 2 = 3
3 * 180 = 540
We have to find out a single angle because it is one side that joins to the other, also if it is a perfect fit then all the single angles must add up to 360.
1080/8 sides = 135 degrees
540 / 5 sides = 108 degrees
540 / 5 sides = 108 degrees
We add these up,
135 + 108 + 108 = 351 which cannot be a possible fit because we need 360 degrees.

The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 1995, and y represents number of new cases. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth. Using this equation, estimate the calendar year in which the number of new cases would reach 887.
The linear regression equation that represents the given set of data is y=0.2x+865.
What is linear regression?Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.
The line of best fit is in the form y=bx+a
The slope is b= [tex]\frac{\sum (x-\bar x)\sum (y-\bar y)}{\sum (x-\bar x)^2}[/tex]
Here, [tex]\bar x[/tex] =(0+1+2+3+4)/5
= 1.8
[tex]\bar y[/tex] = (856+871+924+961+961)/5
= 914.6
∑(x-[tex]\bar x[/tex])=(0-2.5)+(1-2.5)+(2-2.5)+(3-2.5)+(4-2.5)
= -2.5-1.5-0.5+0.5+1.5
= -2.5
∑(y- [tex]\bar y[/tex]) =(865-914.6)+(871-914.6)+(924-914.6)+(961-914.6)+(961-914.6)
= -49.6-43.6+9.4+46.4+46.4
= 9
So, slope b= 1.8×9/9²
b=0.2
Substitute b=0.2 and (0, 865) in y=bx+a, we get
865=0.2×0+a
a=865
Substitute b=0.2 and a=865 in y=bx+a, we get
y=0.2x+865
Therefore, the linear regression equation that represents the given set of data is y=0.2x+865.

Jackie runs and dances for a total of 55 minutes every day. She dances for 25 minutes longer than she runs. Part A: Write a pair of linear equations to show the relationship between the number of minutes Jackie runs (x) and the number of minutes she dances (y) every day. (5 points) Part B: How much time does Jackie spend running every day
Jackie spends 15 minutes running every day.
Part A: The relationship between the number of minutes Jackie runs (x) and the number of minutes she dances (y) every day can be represented by the following pair of linear equations:
Equation 1: x + y = 55 (This equation represents the total amount of time Jackie spends running and dancing every day, which is 55 minutes)
Equation 2: y = x + 25 (This equation represents the relationship between the number of minutes Jackie runs and the number of minutes she dances, which is that she dances 25 minutes longer than she runs)
Part B: To find out how much time Jackie spends running every day, we can substitute the second equation into the first equation:
x + (x + 25) = 55
2x + 25 = 55
2x = 30
x = 15
Therefore, Jackie spends 15 minutes running every day.

Owen is designing a rectangular garden whose length is 25 feet he needs to put fencing all around the exterior of the garden and wants to use less than 8 feet of fencing
Answer:
To enclose the rectangular garden, Owen will need to put fencing along the length of the garden, which is 25 feet, and along the width of the garden. He wants to use less than 8 feet of fencing, so the width of the garden must be less than 8 feet.
The total amount of fencing needed will be equal to the length of the garden plus the width of the garden, multiplied by 2 (since there are two sides to the garden for each of the length and width).
For example, if the width of the garden is 5 feet, the total amount of fencing needed will be 25 + 5 + 25 + 5 = 60 feet, which is less than 8 feet.
So, the width of the garden can be any value less than 8 feet.

Triangle BAC was rotated 90° clockwise and dilated at a scale factor of 2 from the origin to create triangle XYZ. Based on these transformations, which statement is true?
<Z=<A
<B=<Y
<A=<X
<C=<Z
We know that a 90-degree clockwise rotation is the same as a 270-degree counterclockwise rotation, which means that the coordinates of each point in the original triangle BAC will be flipped across the x-axis, and then rotate 270 degrees.
We also know that a dilation at a scale factor of 2 means that the coordinates of each point are multiplied by 2.
Based on these transformations, the statement that is true is <C=<Z
In triangle BAC, point C has the same coordinates as point Z in triangle XYZ.
This because, the original point C is transformed by rotating 90 degrees counterclockwise and scaling by a factor of 2, This result in point C moving to the position of point Z.
The rest of the statements are not true based on this rotation and dilation because the coordinates of points A, B, and Y will be different from the original triangle BAC.
Y=6 and x=-1 parallel or perpendicular line
By plot in graph, we get Y=6 and x=-1 is perpendicular lines.
What is parallel line?Parallel lines are lines in a plane that are always the same distance apart and never intersect. They are coplanar lines that do not intersect each other, and they have the same slope.
What is perpendicular line?Perpendicular lines are lines that intersect at a right angle (90 degrees). In other words, they are lines that are at a 90-degree angle to each other. The slope of perpendicular lines are opposite reciprocals of each other, meaning that if one line has a slope of m, the other line will have a slope of -1/m.

Two parallel lines are cut by a transversal as shown below.
Suppose m<7=107 . Find m<1 and m<4 .
The angle measures : m∠1 = 107° and m∠4= 73°
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
There are 2 parallel lines
A transversal cuts them
∠5 and ∠7 are corresponding angles
Corresponding angles are equal in measures
m∠5 = m∠7
m∠7 = 107°
m∠5 = 107°
∠1 and ∠7 formed a pair of alternate exterior angle.
And m∠1 = m∠7
∠1 and ∠4 formed a pair of linear angle.
The sum of the measures of the linear angles is 180°
m∠1 + m∠4 = 180°
Substitute ∠1 by 107°
m∠4 + 107° = 180°
m∠4 = 180 - 107
m∠4= 73°
Therefore, m∠1 = 107° and m∠4= 73°

Dom is selling pizza at Hoopfest to help him raise money to go on a road trip. He wants each topping to increase the total price at a rate of $1.25. When someone ordered a 3-topping pizza the price was $16.25. Write an equation to represent this data.
Answer:
P = 12.50 + 1.25t
Step-by-step explanation:
To find an equation to represent the price of a pizza, we need to first figure out the original price of a pizze.
Since the price is 16.25 dollars, and there are 3 toppings, each of which cost 1.25, the original price would be:
16.25 - 3(1.25) = 12.50
Thus, we can represent the cost of a pizze with toppings as:
P = 12.50 + 1.25t, where P = Price and t = amount of toppings.
