Answer:

Add 7 black beads

Step-by-step explanation:

Since we can only change the number of black beads, decide how many black beads you will add based on how many white beads there are.

There are three white beads in the picture.

Total beads we will have (b meaning black)     b : 3

                                  Ratio black : white beads 3 : 1

Use the common ratio, which is a number that both sides of the original ratio multiply by to get to the new ratio.

Find common ratio by dividing total by ratio white beads: 3/1 = 3

Multiply ratio black beads by common ratio. 3 X 3 = 9

We need 9 black beads in total.

Check answer

9 : 3     Both sides divisible by 3; reduce ratio

= 3 : 1        Correct ratio

There will be a total of 9 black beads, but we already have 2 black beads:

(9 total) - (2 original) = (7 to add)

Therefore we need to add 7 black beads.

To make the ratio of black to white beads 3:1, you need to add 1 more black bead.

To make the ratio of black to white beads 3:1, we need to determine how many more black beads need to be added. Currently, the ratio is 2:3, which means for every 2 black beads, there are 3 white beads. Let's say we have 2x black beads and 3x white beads. To make the ratio 3:1, we need to have 3 black beads for every 1 white bead. This means we need to add x more black beads. Setting up the equation 2x + x = 3(3x), we can solve for x to find out how many more black beads are needed.

Simplifying the equation, we get 2x + x = 9x. Combining like terms, we have 3x = 9x. Subtracting 3x from both sides, we get 0 = 6x. Dividing both sides by 6, we find that x = 0. Since we need an integer value for x, it means we need to add 1 more black bead to make the ratio 3:1.

Therefore, you need to add 1 more black bead to make the ratio of black to white beads 3:1.

Answer:

$87

Step-by-step explanation:

to find discounted price, you multiply the original price by the decimal equivalent of the discount. so,

[tex]145 \times .40 = 58[/tex]

so that's 40% of 145 but now you gotta take the 40% off the original price so,

[tex]145 - 58 = 87[/tex]

==========================================

Explanation:

Assuming the second "x+1" is all in the denominator, this will cancel with the first "x+1" in the numerator. I'm using the rule that x/x = 1 where x is nonzero.

What happens after the canceling is that f(x) = x-2. This is a linear equation with positive slope (the slope is 1).

The positive slope means the line goes up as we read it from left to right. As x gets larger, y does too. So we can say [tex]\text{ as } x \to \infty \text{ , } y \to \infty[/tex]

Going in reverse, as x heads off to negative infinity, y does the same as well. Therefore, [tex]\text{as } x \to -\infty \text{ , } y \to -\infty[/tex]

Below is the graph attached as an image to help visually verify the two answers. Note the hole at x = -1 which is due to the fact that this x value makes the original unsimplified version of f(x) to be undefined. Recall that we cannot divide by zero so x+1 cannot be equal to zero.

Answer:

y [tex]\leq[/tex] [tex]\frac{-1}{3}x[/tex] + 1

Step-by-step explanation:

To find the inequality represented by the graph, we need to find the linear equation that represents the blue line.

As we can see, the:

y intercept: (0, 1)

x intercept: (3, 0)

So the slope of the equation is:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

= [tex]\frac{0-1}{3-0}[/tex] = [tex]\frac{-1}{3}[/tex]

So use the slope and the slope-point formula, we find the linear expression

The standard form is: y = mx+ b

<=> y = [tex]\frac{-1}{3}[/tex] x + b

Substitute the point (0, 1) to find b, we have:

b= y - [tex]\frac{-1}{3}[/tex] x

<=> b= 1 - 0 =1

So the linear equation is: y = [tex]\frac{-1}{3}[/tex] x + 1

After that, we need to take a test point form the shaded area and evaluate the expression. Let the point be: (1, 2), we have:

2 = [tex]\frac{-1}{3} *1[/tex] +1

<=> 2=[tex]\frac{2}{3}[/tex]

We know that 2 > [tex]\frac{-1}{3}[/tex]  this means that the left inequality sign is ≥ , so the  inequality represented by the graph:

y [tex]\leq[/tex] [tex]\frac{-1}{3}x[/tex] + 1

Answer:

B is the correct answer, as x - 2 in the exponent would move the graph to the right 2.

To find a pricing option with the same unit price as 4 lemons for $0.79, we calculated the unit price per lemon as $0.1975. None of the provided pricing options match this unit price, as they are all significantly higher.

We need to determine the equivalent unit price per lemon to match the store's offer of 4 lemons for $0.79. First, we calculate the unit price for one lemon by dividing the total price of the bag by the number of lemons. So, $0.79 divided by 4 gives us a unit price of $0.1975 per lemon.

Now, let's use this unit price to check which pricing option results in the same unit price. We must find a scenario where each lemon costs $0.1975.

An access fee of $4 and a per-unit price of $4 with 2 units bought would have a unit price of $4, which is too high.

An access fee of $9 and a per-unit price of $4 with 3 units bought would also have a unit price of $4, again too high.

An access fee of $24 and a per-unit price of $3 with 4 units bought would have a unit price of $3, which is also higher than $0.1975.

For the bundle size of 4 units with a bundle price of $36, we would have a unit price of $9 ($36 divided by 4), which is much higher.

The scenario with an access fee of $32 and a per-unit price of $16 for 4 units is also incorrect since the unit price is $16.

None of the given pricing options have a per-unit price of $0.1975.

Graphs of sin and cos : https://brainly.com/question/9554579

Keywords: graphs, sin, cos, quadrant

#LearnwithBrainly

The graphs of sin and cos, while similar in shape and period, are shifted horizontally due to their phase difference. This directly affects their signs in different quadrants, revealing their interconnected nature and dependence on the unit circle representation.

Similarities in Graphs:

Shape: Both sine and cosine graphs share the same sinusoidal wave pattern, meaning they oscillate up and down between their maximum and minimum values.

Period: Both functions have the same period of 2π radians or 360 degrees, meaning they complete one full cycle within this interval.

Amplitude: Both have an amplitude of 1, meaning they oscillate between -1 and 1 on the y-axis.

Shift and Relationship between Signs:

Phase Shift: The cosine graph is essentially the sine graph shifted to the left by π/2 radians (or 90 degrees). This explains why their peaks and troughs don't coincide perfectly.

Signs in Quadrants: This phase shift plays a crucial role in determining the signs of sin and cos in different quadrants:

Quadrant I (0° to 90°): Both sin and cos are positive as they increase in value.

Quadrant II (90° to 180°): Sin remains positive as it continues increasing, but cos becomes negative as it decreases.

Quadrant III (180° to 270°): Both sin and cos are negative as they decrease in value.

Quadrant IV (270° to 360°): Sin becomes positive as it increases, but cos remains negative as it continues decreasing.

Underlying Connection:

These relationships can be further explained by their definitions based on the unit circle:

Sine: sin(θ) represents the y-coordinate of a point on the unit circle when the angle θ is measured from the positive x-axis counterclockwise.

Cosine: cos(θ) represents the x-coordinate of the same point.

Therefore, as θ moves around the circle, the signs of sin and cos change based on their positions relative to the axes.
