jennifer and kim enjoy making bracelets. at the beginning of this year Jennifer had already made twenty five bracelets. she continue to make eight bracelets every month. Kim just started making bracelets recently, so she had only made eleven at the beginning of the year. Kim is able to work more quickly so she makes ten more bracelets every month. write an inequality to model the situation comparing Jennifer and kim

What is 17/100 into a decimal

Answers

The answer is 0.17. To convert fraction to a decimal, you must divide a numerator by a denominator. In 17/100, 17 is the numerator and 100 is the denominator, thus 17/100 = 17 : 100. When you divide by 100, put the decimal spot two spaces from the right-hand side because 100 has two zeros. Therefore: 17/100 = 17 : 100 = 0.1Hope this helps. Let me know if you need additional help!

Answer: 0.17

Step-by-step explanation: To write 17/100 as a decimal, remember that the hundredths place is two places to the right of the decimal point.

This means that 17/100 can be written as the decimal 0.17. Notice that we put the last digit of 19 in the hundredths place.

Help??

Answers

A. The first equation in slope-intercept form is y = -0.5x + 3. The second equation in slope-intercept form is y = 0.6x - 2.

B. The graph of the two equations is attached below.

C. The solution of the system of equation is (4.545,0.727)

A. To write the equations in slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate "y" on one side of each equation.

1. 2x + 4y = 12

First, isolate "y" by subtracting 2x from both sides:

4y = -2x + 12

Next, divide both sides by 4 to get "y" by itself:

y = (-2x + 12) / 4

Simplify the equation:

y = -0.5x + 3

So, the first equation in slope-intercept form is y = -0.5x + 3.

2. 3x - 5y = 10

First, isolate "y" by subtracting 3x from both sides:

-5y = -3x + 10

Next, divide both sides by -5 to get "y" by itself:

y = (-3x + 10) / -5

Simplify the equation:

y = 0.6x - 2

So, the second equation in slope-intercept form is y = 0.6x - 2.

B. To graph the pair of linear equations, plot the y-intercept (where x = 0) and use the slope to find other points.

1. Graph the equation y = -0.5x + 3:

Plot the y-intercept at (0, 3).

Use the slope -0.5 to find another point; for example, if x = 2, then y = -0.5(2) + 3 = 2.

2. Graph the equation y = 0.6x - 2:

Plot the y-intercept at (0, -2).

Use the slope 0.6 to find another point; for example, if x = 3, then y = 0.6(3) - 2 = 0.

C. To estimate the solution to the system of equations, look for the point where the two lines intersect. This point represents the x and y values that satisfy both equations simultaneously. From the graph, we can interpret that the solution of the system of equation is (4.545,0.727)

1)     This format that the two equations are in is called Standard Form, and it's formula is Ax+By=C. Slope-Intercept Form is another form in which linear equations can be written. It's expressed as y=mx+b. See how in SIF (Slope intercept form), the "y" is isolated? All you have to do is isolate the "y" in both equations given to you.

2x+4y=12
-2x       -2x
4y=-2x+12
/4           /4
y=-1/2x+3

3x-5y=10
-3x       -3x
-5y=-3x+10
/-5         /-5
y=3/5x-2

2)     To graph SIF, you need to know what each aspect of the equation is. The formula is y=mx+b.

m stands for slope. A great way to remember it is rise/run (rise over run). Basically, the numerator in "m" is how far up you go to graph each point, and the denominator is how far left or right you go (remember, left is negative, right is positive). Let me give you an example. y=3/5x. In this formula, to graph each point, on the line, you'd go up 3, and to the right 5, then plot a point, then up 3, right 5, plot another one... you get it. What if the equation was y=3x though? The slope would be 3/1, or up 3, right one.

You know how to plot the points, but what coordinate do you startat? That's where the Y-Intercept comes into play. The Y-Intercept is basically where the line crosses the Y-axis. The b in the SIF formula is the y-intercept, and where you plot your very first coordinate on the line. If the SIF equation was y=1x+3, your first coordinate would be on the y axis, at an elevation of 3. Since the y-axis is at x=0, the coordinate would be (0,3). 

3)     Look at the graph now. Where do the lines cross? The x should be somewhere between 4 and 5, and the y is somewhere between 1.5 and 2. Therefor, your "estimation" should be something like (4.5,1.75)

I really hoped this helped you! It took a while to write so I'd appreciate if you'd choose the Brainliest answer -- thanks!

How many permutations can be made of the letters of the word "radar" when taken all at a time?

Answers

The number of permutations can be made of the letters of the word "radar" when taken all at a time is 30.

What is Permutation?

This is defined as ways in which n things can be arranged, taken all at a time.

P(n,r) = n!/(n-r)!

Radar has 5 words with 2r , 2a and 1d which means

5! / 2! 2! 1!

5! = 5×4×3×2×1 = 120

2! 2! 1! = 4

120/4 = 30

3^2x3^9 simplify and write in exponential form

Answers

Answer:

\sf 3 ^(11)

Step-by-step explanation:

An exponent is a mathematical symbol that tells us how many times to multiply a base number by itself.

In this case:

To simplify 3² × 3⁹, we can use the following rule of exponents:

\sf a^m * a^n = a^(m+n)

Therefore, 3² × 3⁹ can be simplified as:

\begin{aligned} 3^2* 3^9 & = 3^(2+9) \n\n &= 3^(11)\end{aligned}

Therefore the answer in exponential form is: \sf 3 ^(11)

Answer:

3^(11)

Step-by-step explanation:

using the rule of exponents

• a^(m) × a^(n) = a^((m+n))

given

3² × 3^(9)

= 3^((2+9))

= 3^(11)
