The simplified expression of √12 (-1+√5) is -2√3 + 2√15

The radical expression is given as:

√12 (-1+√5)

Express √12 as 2√3

So, we have:

√12 (-1+√5) = 2√3(-1+√5)

Evaluate the product

√12 (-1+√5) = (-2√3+2√15)

Remove the bracket

√12 (-1+√5) = -2√3 + 2√15

Hence, the simplified expression of √12 (-1+√5) is -2√3 + 2√15

Answer:

slope = 1/4

Step-by-step explanation:

at a cafeteria the price of a salad depend on it weight in ounces. the graph shows the relationship what is the slope of the line

Find two places where the line neatly intersects the graph. For example, we will use the points: (0 , 0) and (4 , 1)

slope = change in y / change in x

\(slope = \frac{(y_{1} -y_{2} )}{(x_{1} -x_{2} )}\)

slope = (0 - 1) / (0 - 4)

slope = -1 / -4

slope = 1/4

Answer:

34

Step-by-step explanation:

This is somewhat hard to explain for me. I attached a picture/diagram to help.

They are congruent angles.

Angle N, inside the MNP triangle is 34. Which means the adjacent angle is 56.

The interior angles of a triangle add up to 180.

So to find angle M in triangle LNM, we can do 180 - 90 - 56.

Therefore the m<LMN = 34

Answer:

98 degrees

Step-by-step explanation:

angle 3 and angle 4 are supplementary angles, since they together add up to 180 degrees.

Since we know angle 3, we can subtract that from 180 degrees to find angle 4:

180 - 82 = 98.

Therefore, angle 4 is 98 degrees.

A: 49

B:45

C: 20.1

D:114

(3x-11)+(6x-10)+x=180

10x-21=180

10x=201

x=20.1

Based on the information, the hedgehogs have made the better offer

The Turkeys are offering a yearly salary of S(t) = 90000t over the course of eight years. To calculate the present value of each payment, an equation is used:

PV = S(t) * e^(-rt)

The variable "r" denotes a continuous interest rate of 0.03. "t" equals the years from t=0 to the time of payment. By this method, the current value of the Turkeys' offer can be assessed as follows:

PV(Turkeys) = ∫[0,8] 90000t * e^(-0.03t) dt

= 736,918.63

Comparatively, the Hedgehogs propose a yearly salary of S(t) = 80000t for nine years. Utilizing the formula employed in the previous scenario, the following result is derived:

PV(Hedgehogs) = ∫[0,9] 80000t * e^(-0.03t) dt

= 753,472.49

Given these calculations and the presumption that Rogelio may earn a continuous interest rate of 3% on his funds, it would best serve him to accept the Hedgehogs’ item offer since they have offered him a more favorable contract based on the accumulated present value of both contracts.

The GCF of \(16s^3t\), 40s^5, and \(68t^2\) is 2st.

The GCF (Greatest Common Factor) is the largest number or term that can divide evenly into each of the given numbers or terms.

In this case, we need to find the GCF of \(16s^3t, 40s^5, and 68t^2.\)
To find the GCF, we can break down each term into its prime factors.

Let's start with \(16s^3t\):
16 can be factored as 2 * 2 * 2 * 2.
\(s^3\) can be written as s * s * s.
t is already in its prime form.
Now, let's break down \(40s^5\):
40 can be factored as 2 * 2 * 2 * 5.
\(s^5\) can be written as s * s * s * s * s.
Lastly, let's break down \(68t^2\):
68 can be factored as 2 * 2 * 17.
t^2 can be written as t * t.
Now, we can compare the prime factors of each term and find the common factors.

We see that 2 is a common factor, as well as s and t.

However, we need to take the lowest exponent for each variable, so the GCF is 2st.
To verify this, we can divide each term by 2st.

If the result is an integer, then 2st is indeed the GCF.
When we divide \(16s^3t\) by 2st, we get \(8s^2\).
When we divide \(40s^5\) by 2st, we get \(20s^4\).
When we divide \(68t^2\) by 2st, we get 34t.
As we can see, all the divisions result in integers, confirming that 2st is the GCF of the given terms.

The two solutions of the equation:

(6x - 12)/3 + 4 = 18/x

Are x = 3 and x = -3

Here we have the following equation:

(6x - 12)/3 + 4 = 18/x

Notice that in the right side we have x on a denominator, then x can not be zero, so x ≠ 0.

Now, let's start by simplifying the left side:

(6x - 12)/3+  4 = 18/x

2x - 4 + 4 = 18/x

2x = 18/x

Now we can multiply both sides by x so we get:

2x^2 = 18

Now divide both sides by 2:

x^2 = 18/2

x^2 = 9

Finally, apply the square root in both sides:

√x^2 = ±√9

x = ±3

The two solutions are x = 3 and x = -3

Answer:

The probability that Ronald ordered a Jumbo Burger with Regular Fries OR a Chicken Sandwich with a Salad is 23%.

Step-by-step explanation:

A tree diagram shows the probabilities for a sequence of two or more independent events.

For the given problem:

Given probabilities for each event:

Create a tree diagram with the given information (see attachment 1).

The end of each branch should be labelled with its outcome, and the probability of that event should be written along the branch.

To calculate the probability of each combination, multiply the probabilities along the branches.

To find the probability that Ronald ordered a Jumbo Burger with Regular Fries, multiply along the branches representing those events:

⇒ 50% × 25% = 12.5%

To find the probability that Ronald ordered a Chicken Sandwich with a Salad, multiply along the branches representing those events:

⇒ 30% × 35% = 10.5%

On a tree diagram, when moving along the branches (from left to right) we multiply, and when moving down we add.

Therefore, to calculate the probability that Ronald ordered a Jumbo Burger with Regular Fries OR a Chicken Sandwich with a Salad, add the two found probabilities:

⇒ 12.5% + 10.5% =23%

Answer:

0.23 or 23%.

Step-by-step explanation:

To solve this problem, we need to find the probability of two specific combinations: Jumbo Burger with Regular Fries, and Chicken Sandwich with a Salad. We can use an area diagram and a tree diagram to help us visualize the probabilities.

Area Diagram: Attachment

Using the area diagram or the tree diagram, we can see that there are four possible outcomes that meet the criteria: Jumbo Burger with Regular Fries, Jumbo Burger with Curly Fries, Chicken Sandwich with a Salad, and Regular Burger with Regular Fries. We can find the probabilities of these outcomes by multiplying the probabilities of the sandwich and side orders.

Probability of Jumbo Burger with Regular Fries: 0.5 x 0.25 = 0.125

Probability of Jumbo Burger with Curly Fries: 0.5 x 0.4 = 0.2

Probability of Chicken Sandwich with a Salad: 0.3 x 0.35 = 0.105

Probability of Regular Burger with Regular Fries: 0.2 x 0.25 = 0.05

To find the probability of Ronald ordering a Jumbo Burger with Regular Fries or a Chicken Sandwich with a Salad, we need to add the probabilities of these two outcomes:

0.125 + 0.105 = 0.23 or 23%

Therefore, the probability that Ronald ordered a Jumbo Burger with Regular Fries, or a Chicken Sandwich with a Salad is 0.23 or 23%.

Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)

To rotate a point 90 degrees  clockwise about a given point,we can follow these steps -

Translate the coordinates   of the given point so that the center of rotation is at the origin.   In this case,we subtract the coordinates   of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).

Perform the rotation by swapping the x and y coordinates and changing the sign of the   new x coordinate. In this case,we  swap the x and y coordinates of (-5, 3)   to  get (3, -5).

Translate the coordinates back to their original position   by adding the coordinates of the center (0,1)  to the result from step 2. In   this case, we add (0,1) to (3, -5) to get (3, -4).

Therefore, the coordinates   of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).
