Sandra will be paid 72.30 dollars for babysitting for 12 hours.
Explanation
We are told that Sandra earned 60.25 dollars babysitting 10 hours.
If she babysits at the same rate, we are asked to calculate the amount she would earn if she babysits for 12 hours.
Let the amount Sandra is paid for babysitting for 12 hours be x dollars
10 hours = 60.25 dollars
12 hours = x dollars
We can write a mathematical relationship by cross multiplying
10 × x = 12 × 60.25
10x = 723
Divide both sides by 10
(10x/10) = (723/10)
x = 72.3 dollars

Solve the inequality for e:
negative 3 e greater than 21
Group of answer choices
e greater than negative 63
e less than negative 63
e less than negative 7
e greater than negative 7
The solution of the inequality negative 3 e greater than 21 is e less than negative 7.
Inequality:
If the two real numbers or algebraic expressions are related using the symbols >, <, ≥, ≤, then the expression is called an inequality.
Given,
Here we have the statement for the inequality.
"negative 3 e greater than 21".
Now, we have o solve it and then we have to find the value of e.
The given statement is rewritten as the following expression form,
That is,
-3e > 21
Here we need the value of e, so we have to divide both sides by 3, then we get,
=> -e > 7
To remove the negative sign, we have to reverse the inequality, then we get the value of e as
=> e < -7
Therefore, in statement it can be written as "e less than negative 7".

given the function y=3x + 5 find the range uf the domain is (-4,-1,2,5,)
The function we have is:
[tex]y=3x+5[/tex]We are given the domain of the function:
[tex]D=(-4,-1,2,5)[/tex]The domain of a function is the allowed values for x.
And we are asked to find the range, which is the values that the function returns for the x-values of the domain.
To find the range, we need to take the values of the domain, substitute them into the equation, and find the values that the function returns.
For the given domain, the allowed values for x are:
[tex]\begin{gathered} x=-4 \\ x=-1 \\ x=2 \\ x=5 \end{gathered}[/tex]For x=-4
We substitute this value into the function:
[tex]\begin{gathered} y=3x+5 \\ y=3(-4)+5 \end{gathered}[/tex]And solve to find the first value of the range:
[tex]\begin{gathered} y=-12+5 \\ y=-7 \end{gathered}[/tex]For x=-1
Substitute this value into the function:
[tex]\begin{gathered} y=3x+5 \\ y=3(-1)+5 \end{gathered}[/tex]Solve the operations:
[tex]\begin{gathered} y=-3+5 \\ y=2 \end{gathered}[/tex]For x=2
Substitute this value into the function:
[tex]\begin{gathered} y=3x+5 \\ y=3(2)+5 \end{gathered}[/tex]And again, solve the operations:
[tex]\begin{gathered} y=6+5 \\ y=11 \end{gathered}[/tex]For x=5
Substitute this value into the function:

One-fourth of the seventh-grade students
made honor roll in the first quarter. The
number of honor roll students increased by
18 in the second quarter. If 105 students
made honor roll in the second quarter, how
many total seventh graders are there?
There are 348 seventh-grader students in total.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
One-fourth of the students made the honor roll in the first quarter, and it grew by 18 in the second quarter, so add 18, and the total number of students who made the honor roll in the second quarter is 105.
Let the seventh-grade students would be x
As per the given condition, we can write the equation as:
⇒ 1/4 x + 18 = 105
Subtract 18 on both sides of the above equation,
⇒ 1/4 x = 87
Multiply by 4 both sides of the above equation,
⇒ x = 348
Therefore, there are 348 seventh-grader students in total.

Hey there Ms or Mr could you please help me out with this problem?just so you know, this is Pythagorean theorem & Simplifying Radicals My recent tutor said that this is the answer of course no I don't have any doubts I just want to know if this is correct.
When we have a radical, we can simplify it by the rule:
[tex]\sqrt[]{ab}=\sqrt[]{a}\sqrt[]{b}[/tex]So, we have to break down 500 into simpler radicals until we have a radical that can't be broken down. Let's simplify Root(500).
[tex]\sqrt[]{500}=\sqrt[]{50}\sqrt[]{10}[/tex]Now, we can break down Root(50) further.
[tex]\begin{gathered} \sqrt[]{50}\sqrt[]{10} \\ =\sqrt[]{25}\sqrt[]{2}\sqrt[]{10} \end{gathered}[/tex]Now, let's break down Root(10) also, thus we have:
[tex]\begin{gathered} \sqrt[]{25}\sqrt[]{2}\sqrt[]{10} \\ =\sqrt[]{25}\sqrt[]{2}\sqrt[]{5}\sqrt[]{2} \end{gathered}[/tex]We can see:
• Root(25) is 5
,• Also Root(2)*Root(2) is 2 by using the rule:
[tex]\sqrt[]{a}\sqrt[]{a}=a[/tex]Thus, we finally have:

The slope intercept form of the required line is x + y = 5
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
The given line is
x + y = 4
y = -x + 4
Slope of the line = [tex]-1[/tex]
Slope of the line parallel to this line = [tex]-1[/tex]
The line passes through (2, 3)
Equation of the required line
y - 3= -1(x - 2)
y - 3 = -x + 2

The solution of the equation x² - 10x + 24 = 0 is x = 4 or x = 6. Option C is correct.
We are given a quadratic equation:
x² - 10x + 24 = 0
Let us split the middle term, we will get;
x² - 6x - 4x + 24 = 0
x (x - 6) - 4 (x - 6) = 0
(x - 4) (x - 6) = 0
equate each with zero, we will get;
x - 4 = 0 or x - 6 = 0
x = 4 or x = 6
So, the value of x is 4 or 6.
So, option C full fills the required criteria.
Thus, the solution of the equation x² - 10x + 24 = 0 is x = 4 or x = 6. Option C is correct.

What is meant by the term transformation?Image transformations usually involve the modification of various bands of data, such as a single multispectral image either from a number of images acquired at different times of the same area (i.e. multitemporal image data). Image transformations, in either case, generate "new" images from a variety of sources that highlight specific features or characteristics of interest more effectively than the original input images.For the given image point of (6, -7) .
First there is a dilation of 4.
Thus,
Image = (6×4 , -7×4)
Image = (24, -28)
Now, there is translation of 3 units right on x axis and 5 unit upward on y axis; T3,5.
