Answer:
15.8
Step-by-step explanation:
First we need to round to the nearest tenth.
18.134 rounds to 18.1 (since it's closer to 18.1 than 18.2)
2.28 rounds to 2.3 (since it's closer to 2.3 than 2.2)
Then we subtract
18.1-2.3=15.8
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The numbers after rounding off to 10th place is :

Kendra has a painting canvas that is 29 inches wide by 33 inches high. She painted a red rose, which covered 30% of the canvas.
What was the area of the canvas which was covered by the red rose?
Answers
Answer:
287.1 inches of the canvas.
Step-by-step explanation:
To solve this, we need to first figure out the total area of the canvas. To do that, multiply width by height.
29*33=957
Now set up your equation for solving for the area of the canvas that the rose covers.
x/957=30/100
We did it where: x is the area of the rose covers, 957 is the amount of inches that the canvas takes up, and the right side of the equation is the percent.
Now cross multiply.
100x=28,710
Now divide both sides by 100.
x=287.1
The red rose covers 287.1 inches of the canvas.

Step-by-step explanation:
Square root of 45
Square Root of 45: √45 = 6.708
We can find the square root of 45 using the following steps:
Step 1: Check whether the number is a perfect square or not. In this case, 45 is not a perfect square as it cannot be broken down into a product of two same numbers.
Step 2: Once the number is checked, the following process needs to be followed:
If the number is a perfect square, it can be written in this format √x2 = x
If it is not a perfect square, the square root is found using the long division method. It can also be written in its simplified radical form.
Since 45 is not a perfect square, we find its square root using the long division method. The simplified radical form of the square root of 45 is given below.
Simplified radical form of the square root of 45-
45 can be written as a product 9 and 5. Hence, square root of 45 can be expressed as, √45 = √(9 × 5) = 3√5. 45 is not a perfect square, hence, it remains within roots. The simplified radical form of the square root of 45 is 3√5.

Write an equation of the line (4,3) and (9,-2)
Answers
Answer:
y= -x + 7
Step-by-step explanation:
to get the equation of a line is y=mx+b
the slope, m, would be calculated (y1-y2)/(x1-x2)
thus we would substitute in (3--2)/(4-9)
which simplifies to 5/-5
or -1
now we know that m= -1
to solve for b we have to put the equation into point-slope form which is
y-y1= m(x-x1)
this would be y-3 = -(x-4)
y-3 = -x+4
y= -x+7

Answer:
the x- coordinate of the turning point is - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
y = x² + bx + c with y- intercept = (0, - 14 ) then c = - 14 , so
y = x² + bx - 14
To find b substitute (2, 0 ) into the equation
0 = 2² + 2b - 14
0 = 4 + 2b - 14
0 = - 10 + 2b ( add 10 to both sides )
10 = 2b ( divide both sides by 2 )
5 = b , then
y = x² + 5x - 14
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the turning point is
x = - [tex]\frac{b}{2a}[/tex]
y = x² + 5x - 14 ← is in standard form
with a = 1 and b = 5 , then
x- coordinate of turning point = - [tex]\frac{5}{2}[/tex]

Answers

Answer Below....
Step-by-step explanation:
Answer:
4x^2 - 2x + 6
Step-by-step explanation:
The "standard form" of the quadratic equation is ax^2 + bx + c.
Here we have 4x^2 = 2x - 6, whose terms must be rearranged to resemble ax^2 + bx + c. Term 4x^2 stays where it is, but + 2x - 6 on the right side must be moved to the left side, which results in: 4x^2 - 2x + 6

option b) 8*9*11
8*9*11 = 792. cant be the box cuz 792 does not equal 729

option c is the box cuz 729 = 729
What is the domain and the range to this
Answers
Answer:
Look Down below :P
Step-by-step explanation:
If you were looking for if it even has a domain and range let's say if the point (15/4,7) should have read (15/4,17) then a plot of these points appears to show a hyperbola and the x and y (f(x)) axes look like Asymptotes. If the general function has the form f(x)=a/x, then there should be a consistent value for a which can be found be substituting the points in the equation. Take one point (17,15/4) and we get 15/4=a/17, from which a=255/4. f(x)=255 x/4. We have no negative values as examples so we cannot assume that the function is defined for negative values of x. f(x)=255 x/4 fits all the points except for (15/4,7), which is possibly mis-typed. The domain of the function is therefore all values of x>0 and the range of f(x) is f(x)>0, assuming continuity and extrapolation of the function.
If the point (15/4,7) is valid then f(x) as defined above is invalid or incomplete. f(x) may be a piece wise function where f(x)=7 if and only if x=15/4. For 0<x<15/4 and x>15/4, f(x)=255 x/4. These would be the domain for x. The range of f(x) is f(x)>0 and f(x)=7 only when x=15/4.

What is the image of the point (-5, -9) after a rotation of 90° counterclockwise
about the origin?
Answers
Answer:
(9, -5)
Step-by-step explanation:
If you rotate a figure 90 degrees counterclockwise, the coordinates will go from (x, y) to (-y, x).
So, let's start out with -y. The y-value of (-5, -9) is -9, and the negative value of that is -(-9) or 9. That goes first in our point: (9, x.) Now, we just keep our x-value the way it is, -5, and put that in our y-value: (9, -5). And there's our point after a 90 degree counterclockwise rotation.

x+y=7
2x+y=10
Answers
Answer:
x = 3, y = 4
Step-by-step explanation:
First, set the first equation equal to x. Note the equal sign, what you do to one side, you do to the other.
Subtract y from both sides of the equation:
x + y = 7
x + y (-y) = 7 (-y)
x = 7 - y
Next, plug in 7 - y for x in the second equation:
2x + y = 10
2(7 - y) + y = 10
Simplify. First, distribute 2 to all terms within the parenthesis:
2(7 - y) = (2 * 7) + (2 * -y) = 14 - 2y
Next, combine like terms. Like terms are terms with the same amount of the same variables:
14 - 2y + y = 10
14 (-2y + y) = 10
14 - y = 10
Isolate the variable, y. First, subtract 14 from both sides of the equation:
-y + 14 (-14) = 10 (-14)
-y = 10 - 14
-y = -4
Next, isolate the variable, y, by dividing -1 from both sides of the equation:
(-y)/-1 = (-4)/-1
y = -4/-1 = 4
Next, plug in 4 for y in one fo the given equations:
x + y = 7
x + (4) = 7
Isolate the variable, x. Subtract 4 from both sides of the equation:
x + 4 (-4) = 7 (-4)
x = 7 - 4
x = 3
x = 3, y = 4

Answer:
Evan's plant is 80 millimeters taller than Raj's plant
Step-by-step explanation:
If the plant will grow 1 centimeter every month, we can write an equation that relates the height of the plant with the number of months elapsed:
Let
H = height of the plant
M = number of months elapsed
H0 = initial height = 10cm
H (M) = (1)M + H0
H (M) = (1)M + 10
Where (1) is the constant rate of growth of 1 centimeter per month.
This is the equation of a line that intersects the H axis at H = 10.

Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles how many red marbles does it contain
Answers
If a bag has 30 orange marbles then that means it has 42 red marbles
Step-by-step explanation:
If there are 7 red marbles for every 5 orange marbles then what you would do is.
30/5=6
6*7=42
Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles Then the bag contains 42 red marbles.
In the problem, we are given that each bag of marbles contains 7 red marbles for every 5 orange marbles. We need to find the number of red marbles when there are 30 orange marbles in the bag.
Let's represent the number of red marbles as R and the number of orange marbles as O.
According to the information provided, we have the following relationship:
R / O = 7 / 5
Now, we are given that the number of orange marbles (O) in the bag is 30. We can substitute this value into the equation:
R / 30 = 7 / 5
To find the number of red marbles (R), we can cross-multiple
R = (7 / 5) * 30
R = 42
Therefore, the bag contains 42 red marbles.
In summary, we used the given ratio of red to orange marbles in the bag to set up a proportion and then solved for the number of red marbles when the number of orange marbles was known. This allowed us to find that there are 42 red marbles in the bag.
