A necklace is made of 12 red beads and 18 orange beads. How many red beads would be needed to make the same necklace with 90 orange beads

Answer:

r = 1

Step-by-step explanation:

The equation is,

→ 6r - 1 + 6r = 11

Now the value of r will be,

→ 6r - 1 + 6r = 11

→ 12r = 11 + 1

→ r = 12/12

→ [ r = 1 ]

Hence, the value of r is 1.

Answer:

The answer is 1 r is equal to 1

Answer: -36 feet

Step-by-step explanation:

72-18 = 54 feet ascended

54 feet / 3 ascents = 18 feet per ascent

18 feet * 2 ascents = 36 feet

-72+ 36 = -36 feet

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answer:

The distance of the whole trip is 50 miles.

Step-by-step explanation:

Let the distance of the whole trip be x.

70% x = 35 miles

(70/100)x = 35 miles

x = 35 * (100/70) miles

x = 50 miles

Therefore, the distance of the whole trip is 50 miles.

Hope this helped!

Answer:

Answer:

y = x + 3

Step-by-step explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3).  The y-intercept is also represented by (0, 3).  The graph also goes through (-3, 0).  The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3.  Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution.  In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer:

y=4x-6

Step-by-step explanation:

The equation of the line is y=mx+c where m is the slope and c is the intercept.

To find the slope, take two points \((x_{1},y_{1})\) and \((x_{2},y_{2})\) and use the equation \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\). Let's take (1,-2) and (2,2) as our two points:

\(m=\frac{2-(-2)}{2-1}=\frac{4}{1}=4\)

The y-intercept is where the line crosses the y-axis. We can see from the graph that the line crosses the y-axis at -6, therefore c= -6.

Now we can write the equation of this line: y=4x-6

Answer:

The answer is y=4x-6

Answer: Player B is the most consistent, with an IQR of 3.5.

Step-by-step explanation:

For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).

For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).

Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Step-by-step explanation:

Let me know if im wrong and I will fix it.

Based on the given information, where there are 7 blue marbles and 3 purple marbles, and assuming the selection process is random and each marble has an equal chance of being selected, the best prediction for the number of times you will pick a blue or a purple marble can be calculated as follows:

Out of the 60 selections, we can expect to pick a blue marble approximately 7/10 times (since there are 7 blue marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a blue marble is around 60 * (7/10) = 42 times.

Similarly, we can expect to pick a purple marble approximately 3/10 times (since there are 3 purple marbles out of a total of 10 marbles). Therefore, the best prediction for the number of times you will pick a purple marble is around 60 * (3/10) = 18 times.

Hence, the best prediction is that you will pick a blue marble around 42 times and a purple marble around 18 times out of the 60 selections.

~~~Harsha~~~

Answer:

18 times

Step-by-step explanation:

If there are 7 blue marbles and 3 purple marbles, the probability of selecting a blue marble is 7/10, and the probability of selecting a purple marble is 3/10.

Since you're selecting marbles without replacement, the probability will change with each pick. To calculate the best prediction for the number of times you will pick a blue or purple marble, we can multiply the probabilities by the number of picks.

Expected number of blue marbles picked: (7/10) * 60 = 42

Expected number of purple marbles picked: (3/10) * 60 = 18

Therefore, the best prediction is that you will pick a blue marble approximately 42 times and a purple marble approximately 18 times when selecting marbles without looking 60 times.

 To know where to put the dots on the graph, use the coordinates you've just been given:

Example: (4,8)

Move to the 4 on the x-axis (the line on the bottom going horizontal)

Then, move up 8 units (up to the 8 on the y-axis)

Place the point at that spot.

Answer:

C. j=2 and h=4

Step-by-step explanation:

Step 1: Create a system of equations for your problem based off what we know.

- we should know that the equation to find the perimeter of something is

\(P= 2l+2w\) where P is the perimeter, l is the length, and w is the width.

- we know that the perimeter of Rectangle P is 20 inches and that the perimeter of Rectangle Q is 30

- we know the length and width of both rectangles

Using this information, lets set up our system.:

\(\left \{ {{20=2(j+4)+2h} \atop {30=2(3h)+2(j+1)}} \right.\)

Step 2: Using the top equation we're going to try to solve for one of the variables. I chose to solve for variable j.

\(20=2(j+4)+2h\)

Start by distributing 2 into j + 4.

\(20=2j+8+2h\)

Now subtract 8 from both sides of the equation.

\(12=2j+2h\)

Now isolate variable j by subtracting 2h from both sides of the equation.

\(12-2h=2j\)

Now condense the equation into simple terms by dividing both sides by its GCF 2 then reorder to get j on the left.

\(j=6-h\)

Step 3: Now that we solved for variable j we can now substitute j into one of our equations from the original system. I chose to use the bottom equation and chose to distribute it before substituting.

\(30=6h+2j+2\)

Subtract two from both sides to isolate the variables

\(28=6h+2j\)

Now we can plug j into our equation

\(28=6h+2(6-h)\)

Step 4: Distribute 2 into 6-h

\(28=6h+12-2h\)

Step 5: Combine like terms

\(28=4h+12\)

Step 6: Subtract 12 from both sides of the equation

\(16=4h\)

Step 7: Divide both sides by 4

\(4=h\)

Now that we know that h=4 we can plug 4 into one of our earlier equations. I used j=6-h

\(j=6-4\\j=2\)

Plug answers into either one of the original equations to check answer

Answer: h ≥ 60

Step-by-step explanation:

≥ means more than or equal to

to be able to ride the roller coaster their height must be more than or equal to 60.

Answer: h ≥ 60

Step-by-step explanation:

h < 60 means that the height is less than 60

h  > 60 means that the height is more than 60

h ≥ 60 means that the height is 60 or more

h ≤ 60 means that the height is 60 or less

So the answer would be h ≥ 60 because the height is at least 60 or more
