Answer: 1
Step-by-step explanation:
The ones place is the place furthest to the right before the decimal. In this case, the decimal is implied because 431 is a whole number. 431 can also be written as 431.0 which more clearly shows this.
The ones place contains the value 1.
In case you need it later,
The tens place is 3 and the hundreds place is 4.

Step-by-step explanation:
(0,-5) (3,3)
Equation of a straight line:
[tex]\displaystyle\\\frac{x-x_1}{x_2-x_1} =\frac{y-y_1}{y_2-y_1} \\\\x_1=0\ \ \ \ x_2=3\ \ \ \ y_1=-5\ \ \ \ y_2=3\\\\Hence,\\\\\frac{x-0}{3-0} =\frac{y-(-5)}{3-(-5)}\\\\\frac{x}{3} =\frac{y+5}{3+5} \\\\\frac{x}{3} =\frac{y+5}{8} \\[/tex]
Multiply both parts of the equation by 24:
[tex](8)(x)=(3)(y+5)\\8x=(3)(y)+(3)(5)\\8x=3y+15\\8x-15=3y+15-15\\8x-15=3y[/tex]
Divide both parts of the equation by 3:
[tex]\displaystyle\\\frac{8}{3}x-5=y[/tex]
Find the derivation of y=sin (2x2 + 3x-4)<br />a. -cos (4x +3) b. -(6x2+3) cos (2x3+3x-4) c. Cos (2x3+3x-4)<br />d. (6x3+3) cos (2x3+3)<br />
Let y = f(x)
f(x) = sin x
g(x) = (2x^2 + 3x - 4)
Use the chain rule.
We want y' = f' (g(x)) • g'(x).
y' = cos(2x^2 + 3x - 4) • (4x + 3)
Done.

There are four activities on the critical path. Coincidentally, their standard deviations are all equal to 4. The standard deviation of the critical path is therefore equal to:
Answer:
the standard deviation of the critical path is 8
Step-by-step explanation:
The computation of the standard deviation of the critical path is shown below:
As we know that
Variance = Standard deviation^2
Now the variance of the critical path is
= Variance 1 + variance 2 + variance 3 + variance 4
= 4^2 + 4^2 + 4^2 + 4^2
= 64
Now the standard deviation would be
= √64
= 8
hence, the standard deviation of the critical path is 8
Help :) Round to the nearest 10ths
Answer:
A=0.6
Step-by-step explanation:
Answer:
0.6 is your answer
Step-by-step explanation:
the tenths place is the 1st number after the decimal which would be 5 and you would want to round that up to 6 because the number after it is iver 5 (closer to 10 than it is 1)

Charles drove three times as far as Emily. Altogether they drove 112 miles. What was the number of miles driven by Charles?
Answer: Charles drove 84 miles
Step-by-step explanation:
(c)harles = 3 x (e)mily
e + c = 112
Since Charles is 3x Emily, we can plug in 3e instead of c
e + 3e = 112
4e = 112
e = 112/4
e = 28
Emily drove 28 miles, and Charles drove 3x that, so Charles drove
28 x 3 = 84

How do you solve this equation step-by-step? (below)
-2 (x - 3) = 16
Answer:
-2 (x -3 ) = 16 (use the distributive property)
-2x +6 = 16 (subtract 6 from both sides)
-2x = 10 (divide both side by -2)
x= -5

Mitch works at Comedy Cinema's concession stand. He has
helped 16 customers so far today. Find the cost of each person's
purchase and write it in the table. Then solve the riddle by writing
the letter of each answer in its matching blank.
Answer:
Step-by-step explanation:
Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p, q, and r are specific rational numbers); using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable.
Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. They recognize the steps as being the same.
Students solve equations for the value of the variable using inverse operations; by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse).
A company’s equipment manager buys $7,000 worth of equipment. This equipment depreciates 19% each year. The manager can replace the equipment after its value falls below $500. After how many years can the manager first replace the equipment?
Answer:
13 (c)
Step-by-step explanation:
Graph the equation 7000(1-0.19)^x and then the inequality y<500, the point of intersection should be 12.524, so the answer will be rounded up to 13 i think

Answer:
1/5 = 3/15
2/3 = 10/15
When all Added up
= 13/15
Step-by-step explanation:
So our LCD here is 15.
So in order to go from 5 to 15, we multiply by 3, and In order to go from 3 to 15, we multiply by 5. What we do to the denominator we also do to the numerator.
So,
[tex]\frac{1}{5} x \frac{3}{3} = \frac{3}{15}[/tex]
And,
[tex]\frac{2}{3} x \frac{5}{5} = \frac{10}{15}[/tex]
So there you go, multiply for what you need to get to the LCD, and what is done to the numerator is also done to the denominator. Enjoy

Describe the correlation if r = -0.45.
The length of a rectangle is 12 inches more than its width. The perimeter is 280 inches. Find the length and the width of the rectangle.
Answer:
width = 64 inches
lenght = 76 inches
Step-by-step explanation:
2(x + 12) + 2x = 280
2x + 24 + 2x = 280
4x = 280 - 24
4x = 256
x = 256/4
x = 64

please help me
Answer:
x = [tex]\frac{-6}{7+\sqrt{13}}[/tex]
r = [tex]\frac{1+\sqrt{13} }{2}[/tex]
Step-by-step explanation:
In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio.
For example, the sequence 2, 6, 18, 54, ... is a geometric progression with common ratio 3. Similarly 10, 5, 2.5, 1.25, ... is a geometric sequence with common ratio 1/2.
-----
Let's take r=ratio of the geometric sequence
in first term, x is multiplied by [tex]r^{0}[/tex]
First term: x [tex]r^{0}[/tex]
Second term: 4x+3 = x [tex]r^{1}[/tex]
Third term: 7x+3 = x [tex]r^{2}[/tex]
From the last 2 equation, we have to obtain r and x values.
Second equation - First equation:
3x = x r (r - 1)
Let's state: x different from 0, so we can simplify x, obtaining:
3 = [tex]r^{2}[/tex] - r
0 = [tex]r^{2}[/tex] - r - 3
r = [tex]\frac{1+\sqrt{13} }{2}[/tex] (only the positive value of r counts)
so, going to second term of the sequence:
4x+3 = x [tex]r^{1}[/tex] => x (4 - [tex]\frac{1+\sqrt{13} }{2}[/tex] ) = -3
x ([tex]\frac{7+\sqrt{13} }{2}[/tex] ) = -3 => x = [tex]\frac{-6}{7+\sqrt{13}}[/tex]
hope it helps..

an electrician cuts a 27 ft piece of wire into two pieces. one piece is 23 ft longer than the other. how long's are the pieces?
Answer:
Step-by-step explanation:
27-23=4
4 divided by 2=2 so
1 piece is 2ft and one piece is 25 ft
23+2ft=25 ft + 2ft =27 ft
The actual distance between Singapore and Jakarta is 1000 km. On a particular map. 1 cm on
the map represents 200 km on the ground. What length on the map represents the distance
between the two cities?
5 cm
10 cm
15 cm
Answer:
5cmStep-by-step explanation:
From the questions;
1cm represents 200km on the map
If the length of distance between the cities is 1000km, the distnce on the map will be say x;
x cm = 1000 km
Divide both equations;
1/x = 200/1000
Cross multiply;
200x = 1 * 1000
200x = 1000
x = 1000/2000
x = 5cm
Hence the length on the map that represents the distance between the two cities is 5cm
