Answer:
Hope this helps :)
If it is seven and three thousandths then the answer would be...
7.003
This is because after the decimal the first place is tenths, then, hundredths, and lastly, thousandths. So the 3 would be in the thousandths place. Also, 7 is in the ones place which is before the decimal.

9.9 81
The sum of the multiples of 9 till 81 is 405 by arithmetic progression.
We have to sum the multiples of 9 up to 81
= 9 + 18 + … + 45 + …+ 72 + 81
We will use arithmetic progression for this.
we get that:
initial term = a = 9
Common difference = d = 9
n = 9
Sum of terms = n / 2 ( 2 a + ( n - 1) d )
Sum = 9 / 2 (2( 9) + 8 ( 9))
sum = 9 / 2 (18 + 72)
Sum = 9 / 2 ( 90)
Sum = 810 / 2
Sum = 405
Therefore, we get that, the sum of the multiples of 9 till 81 is 405 by arithmetic progression.

Zeros of a Polynomial Function
An important consequence of the Factor Theorem is that finding the zeros of a
polynomial is really the same thing as factoring it into linear factors. In this section we
will study more methods that help us find the real zeros of a polynomial, and thereby
factor the polynomial.

If the intquantity and decprice variables contain the numbers 3 and 15.75, respectively, the condition if intquantity > 0 andalso intquantity < 10 orelse decprice > 20 will evaluate to ____.
The correct option is c. True.
If the intquantity and decprice variables contain the numbers 3 and 15.75, respectively, the condition if intquantity > 0 and also intquantity < 10 or else decprice > 20 will evaluate to "True."
What is C++?C++ is an object-oriented programming (OOP) language that many consider to be the best for developing large-scale applications.
C++ is a subset of the C programming language. Java is a programming language that is similar to C++ but is optimized for the dispersion of program objects over a such as the Internet.
Now, as per the question, construct a program in C++.
#include <iostream>
using namespace std;
int main()

int intQuantity = 3;
int decPrice = 15.75;
if (intQuantity >0 && intQuantity <10 || decPrice>20){
cout<<"True";
}
else{
cout<<"False";
}
return 0;
}
Because the condition if (intQuantity >0 && intQuantity 10 || decPrice >20) evaluates to true, the output from in this program will be "True." The reason for this is that in programming, the Logical Or (| |) evaluates to true when either or both conditions are met.
Although the condition decPrice>20 is false in the question, the very first condition intQuantity >0 && intQuantity 10 is true, so the OR evaluates to true.

leo drew a line that is perpendicular to the line shown on the grid and passes through point f g. which of the follwoing is the equation of leos lins
The equation of Leo's line is given by: 3 (y - G) = ( F - x)
What is the equation of a line to the curve?A line's equation has the standard form ax + by + c = 0. Here, the variables are x and y, the coefficients are a and b, and the constant term is c. It is a first-order equation with the variables x and y. The coordinates of the point on the line shown in the coordinate plane are represented by the values of x and y.Given: An equation of a line on a grid, about which another line is perpendicularly.
To find: Equation of the perpendicular line.
Finding:
Firstly, we will find the equation of the given line.As we can see, the given line passes through (1,1) and (2,4), in the general equation of the line: [tex]y-y_0=m(x-x_0)[/tex],=> m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{4-1}{2-1}=\frac{3}{1} = 3[/tex]
The equation of the line becomes: [tex]y-y_0=3(x-x_0)[/tex]
2. Since the line passes through (1,1), the final equation of the line can be given by:
=> y - 1 = 3 ( x - 1)
=> y = 3x - 3 + 1
=> y = 3x - 2
Now, for the equation of the perpendicular line:The slope of the line will be given by:=> m' = -1/m
=> m' = -1/3
The equation of the perpendicular line will now be: [tex]y-y_0=\frac{-1}{3}(x-x_0)[/tex]=> [tex]3(y-y_0)=(x_0-x)[/tex]
2. Since the perpendicular line passes through the point (F,G), the equation of the line will be: 3 (y - G) = ( F - x).
Hence, The equation of Leo's line is given by: 3 (y - G) = ( F - x).

jason says you can solve an inequality by replacing the inequality sign with an equal sign and putting it back in after solving the equation. do you agree?
Jason is incorrect, because inequality signs change when we multiply/divide by negative numbers, and we need to follow the signs to make sure we use the correct one.
Is Jason correct whit his claim?Well, Jason says that you can solve an inequality by replacing the sign by an equal sign, solve the equation as you already have done a thousand times, and then put the inequality sign again.
Now, this is clearly incorrect, because inequalities have a really nice property. If you multiply or divide both sides of the inequality by a negative number, then the "direction" of the sign changes.
This means that if we have an inequality like:
-2x > 10
And we divide both sides by -2, we should get:
x < 10/-2
x < -5
Where the direction of the sign changed.
If you did what Jason said, the direction of that sign would not have changed, and thus, you would have got an incorrect solution for the inequality.

Standard Deviation:
Standard deviation is a measure of the dispersion of a set of numerical values from their mean.
The general form of the standard deviation is,
[tex]SD=\sqrt{\frac{\sum (x_i-\bar{x})}{n} }[/tex]
where
xi is each value in the data set,
x-bar is the mean, and
n is the number of values in the data set.
Given,
Mean = 21.
Standard deviation = 5
Wayne's standardized score on the act = −0.6 .
Here we need to find the Wayne's Actual ACT score.
Let x be the Wayne's Actual ACT score.
So,
=> z-score = (x - mean)/SD
Apply the values on it,
=> -0.6 = (x - 21) / 3

Answer:its 180 cm
Step-by-step explanation:
If ef=x-4, fg=2x-19, and eg= 13 what is x
The value of x is 12.
Given on a line lie three points e, f and g.
therefore, ef = x ₋ 4
fg = 2x ₋ 9 and
eg = 13
we can say that ef and fg must add upto eg.
⇒ ef ₊ fg = eg
⇒ x ₋ 4 ₊ 2x ₋ 19 = 13
⇒ 3x ₋ 23 = 13
⇒ 3x = 13 ₊ 23
3x = 36
x = 36/3
x = 12
hence we get the value of x as 12.
now substitute x value to get ef and fg values.
ef = x ₋ 4 = 12 ₋ 4 = 8
fg = 2x ₋ 19 = 2(12) ₋ 19 = 24 ₋ 19 = 5
Hence we get the value of x as 12.

Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.
Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.
Given:
For 1 1/2 or 3/2 hours tony charges = $37.50
For 1 hour tony charges = 37.50 * 2/3

Function 2
Δx = 5 - 1 = 4; Δy = - 1 - 1 = - 2
Δx = 9 - 5 = 4; Δy = - 3 - (- 1) = - 2
Δx = 13 - 9 = 4; Δy = - 5 - (- 3) = - 2
The function is linear.
Function 3
Δx = 5 - 4 = 1; Δy = - 10 - (- 5) = - 5
Δx = 6 - 5 = 1; Δy = - 13 - (- 10) = - 3
Δx = 7 - 6 = 1; Δy = - 15 - (- 13) = - 2
The function is not linear.
Function 4
Δx = 1 - (- 2) = 3; Δy = 5 - 4 = 1
Δx = 4 - 1 = 3; Δy = 6 - 5 = 1

To fence the triangular section Mr. Johnson has to find the perimeter of the triangular field.
To find the perimeter of the triangle one has to add the length of all the three sides of the triangle.
Similarly we can also find the perimeter of other plane figures by adding the lengths of all the sides of the figure.
Suppose if the length of the sides of a triangle is a,b and c units.
Then the perimeter of the triangular field will be = (a + b + c) units.

A bag contains 3 blue chips, 7 red chips, 4 yellow chips, and 5 green chips. A chip is randomly drawn from the bag. Find probability.
P( red or blue )
If a chip is randomly drawn from the bag, the probability it will be a red or a blue one is P(red or blue) = 10/19.
Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,
P(A) = n(A)/n(S)
where:
n(A) = number of event A
n(S) = number of all possible outcomes or sample space.
Suppose A and B are independent outcomes, then:
P(A or B) = P(A) + P(B)
In the given problem:
Number of chips:
Blue = 3
Red = 7
Yellow = 4
Green = 5
Total chips = 3 + 7 + 4 + 5 = 19
If a chip is randomly drawn, the probability it will be a red one is:
P(red) = 7/19
Similarly,
P(blue) = 3/19
Using the probability formula for independent outcomes:
P(red or blue) = P(red) + P(blue)
= 7/19 + 3/19 = 10/19
