whats the answer? help please!!

Step-by-step explanation:

2y² = 13y

2y² − 13y = 0

y (2y − 13) = 0

y = 0, y = 13/2

It can be tempting to divide by y at the beginning, but if you do, you lose one of the solutions.  Instead, move everything to one side and factor.

The solutions to the equation 2y²=13y are y = 0 and y = 6.5. This is achieved by setting up the equation to zero, factoring it out and applying the zero product property.

To solve the provided equation, 2y²=13y, you'll need to set the equation to zero by moving all the terms to one side: 2y² - 13y = 0. This becomes a quadratic equation in the form ax² + bx + c = 0.

Factor the equation by taking out a common factor of 'y', yielding y(2y - 13) = 0. According to the zero product property, if a product is zero then at least one of the factors must be zero. This means that y = 0 or 2y - 13 = 0. Solving the second equation gives y = 6.5.

So, the solutions of the equation are y = 0 and y = 6.5.

Answer:

32

Step-by-step explanation:

put the numbers in order from less to greatest

3,13,14,16,27,37,42,64,95,97

the middle numbers are 27 and 37

27+37 is 64

64 divided by 2 is 32

First put the numbers in order from least to greatest

3, 13, 14, 16, 27, 37, 42, 64, 95, 97

Median means middle so find the middle number by deleting the least and greatest number in each "layer"

3, 13, 14, 16, 27, 37, 42, 64, 95, 97

   13, 14, 16, 27, 37, 42, 64, 95

         14, 16, 27, 37, 42, 64

               16, 27, 37, 42

                     27, 37

You have two numbers left. To find the middle take the mean of these two numbers, by adding them together then dividing the sum by two

27 + 37 = 64

64 / 2 = 32

32 is the median!!!

5t=41

The equation to determine the cost, c, of each zoo ticket when five zoo tickets cost a total of $41 is 'c = $41 / 5'.

To find the cost of each zoo ticket, we need to divide the total cost of all the tickets by the number of people. Given that 5 people's zoo tickets cost a total of $41, we can set up the equation for this situation like this:

c = $41 / 5

Here, 'c' represents the cost of each zoo ticket in dollars. The equation suggests that when you divide the total cost ($41) by the total number of tickets (5), you get the cost of each individual ticket (c).

Answer:

Final answer is [tex]\frac{8}{9}[/tex] of a jar.

Step-by-step explanation:

Given that Archie used 1/3 of a jar of tomato sauce to make 3/8 of a pizza. Now we need to find about how many jars of tomato sauce will Archie need to make one whole pizza.

We can setup ratio of sauce and pizza to easily solve that problem.

Let amount of sauce needed to make 1 pizza = x

then ratio will be :

[tex]\frac{sauce}{pizza}=\frac{x}{1}=\frac{\frac{1}{3}}{\frac{3}{8}}[/tex]

[tex]\frac{x}{1}=\frac{\frac{1}{3}}{\frac{3}{8}}[/tex]

[tex]x=\frac{\frac{1}{3}}{\frac{3}{8}}[/tex]

[tex]x=\frac{1}{3}\cdot\frac{8}{3}[/tex]

[tex]x=\frac{8}{9}[/tex]

Hence final answer is [tex]\frac{8}{9}[/tex] of a jar.

As we know distance equals speed multiplied by time

118*2.25=265.5

Therefore the car can travel 265.5km in 2 hours 15 minutes with the speed of 118km/h

The van can travel approximately 265.5 kilometers in 2 hours and 15 minutes.

To find out how far the van can travel in 2 hours and 15 minutes, we need to use the formula:

Distance = Speed × Time

Given:

- Speed of the van = 118 km/h

- Time = 2 hours 15 minutes

First, let's convert the time to hours:

2 hours 15 minutes = 2 + 15/60 hours

= 2.25 hours

Now, we can use the formula to calculate the distance:

Distance = 118 km/h × 2.25 hours

Distance ≈ 265.5 km

Therefore, the van can travel approximately 265.5 kilometers in 2 hours 15 minutes.

any given point in a circle is equal distance from the center

Answer: TRUE.

Step-by-step explanation:

It knows that the distance "d" between any two points is equal to [tex]\sqrt{(x-x_0)^2-(y-y_0)^2}[/tex].

In a circle the distance between a point that belongs to the circumference and the center ([tex]x_0,y_0[/tex]) is always the same. Then:

[tex]\sqrt{(x-x_0)^2-(y-y_0)^2}[/tex] is always equal to a constant called "r".

This is:

[tex]\sqrt{(x-x_0)^2-(y-y_0)^2}=r[/tex]

Square both sides of the equality:

[tex](\sqrt{(x-x_0)^2-(y-y_0)^2})^2=r^2[/tex]

[tex](x-x_0)^2-(y-y_0)^2=r^2[/tex]

Note that we obtain the General equation of a circle.

This prove that if the distance between a given point in the plane and a collection of points is equal, then the equation of a circle is obtained.

Therefore, the statement "A circle is the collection of points in a plane that are the same distance from a given point in the plane." is true.

Answer:

4/63

Step-by-step explanation:

The probability of first choosing a blue golf ball and then a pink golf ball, without replacement, from the pocket is 4/63.

The question asks for the probability of selecting a blue golf ball and then a pink golf ball from a pocket that contains 15 white, 8 pink, 3 yellow, and 10 blue golf balls, without replacement. To solve this, we need to find the probabilities of each event happening sequentially and then multiply them.

Firstly, the probability of choosing a blue ball initially is 10 out of the total number of balls (15 white + 8 pink + 3 yellow + 10 blue), which gives us 36.

Therefore, the probability is 10/36 or 5/18. Once a blue ball has been chosen, it is not replaced, so the total count of balls is reduced by one, making it 35, and the count of blue balls is now 9.

Secondly, with the blue ball removed, we now calculate the probability of choosing a pink ball. There would still be 8 pink balls, so the probability of now choosing a pink ball is 8 out of the remaining 35 balls. This gives us the probability of 8/35.

To find the overall probability of both events happening in sequence (first a blue ball, then a pink ball), we multiply the individual probabilities: (5/18) × (8/35) = 40/630, which can be simplified to 4/63.

The volume of the square pyramid is [tex]V=216\ in^{3}[/tex]

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

[tex]V=\frac{1}{3}b^{2}h[/tex]

we have

[tex]b=9\ in[/tex]

[tex]h=8\ in[/tex]

substitute

[tex]V=\frac{1}{3}(9)^{2}(8)[/tex]

[tex]V=216\ in^{3}[/tex]

The relationship is that (P) and (T) shows how many people come in that amount of time. Sorry I dont if that will work.

The relationship between the number of people (p) and time in hours (t) is represented by the linear equation p = 25t, where m = 25 is the slope, and b = 0 is the y-intercept.

To determine the relationship between the number of people (p) who bought tickets and the time in hours (t), we can use a linear equation of the form p = mt + b, where m is the slope and b is the y-intercept.

Looking at the table, we can observe that for every 1-hour increase in time, the number of people increases by 25. This indicates that the slope (m) is 25. To find the y-intercept (b), we can use the initial point (0, 0) from the table.

Substitute these values into the equation: 0 = m(0) + b.

Solving for b, we get b = 0.

Therefore, the equation describing the relationship is p = 25t, where p is the number of people and t is the time in hours.

Step-by-step solution:

1. Identify the slope (m): From the table, the number of people increases by 25 for each 1-hour increase in time, so m = 25.

2. Find the y-intercept (b): Use the initial point (0, 0) in the equation 0 = m(0) + b to find that b = 0.

3. Write the equation: The relationship is p = 25t, where p is the number of people and t is the time in hours.

Answer:

0.589

Step-by-step explanation:

THis is a conditional probability question. Let's look at the formula first:

P (A | B) = P(A∩B)/P(B)

" | " means "given that".

So, it means, the "Probabilty A given that B is equal to Probability A intersection B divided by probability of B."

So we want to know P (Female | Undergraduate ). This in formula is:

P (Female | Undergraduate) = P (Female ∩ Undergraduate)/P(Undergraduate)

Now,

P (Female ∩ Undergraduate) means what is common in both female and undergraduate? There are 43% female that are undergrads. Hence,

P (Female ∩ Undergraduate) = 0.43

Also,

P (Undergraduate) is how many undergrads are there? There are 73% undergrads, so that is P (undergraduate) = 0.73

plugging into the formula we get:

P (Female | Undergraduate) = P (Female ∩ Undergraduate)/P(Undergraduate)

=0.43/0.73 = 0.589

this is the answer.

Answer:

No solution

Step-by-step explanation:

Anyone of the values of x satisfies the equation. We can see it even calculating with basic math. If x is 0, then -41 -2(0) + 61 = -24

-41 +61 =-24

20 = -24 is incorrect

If x is -6, then -41 -2(-6) =-24

-41+12=-24

-29 = -24 incorrect.

If x is 6, then -41-2(6) + 61 = -24

-41-12+61 = -24

-53 + 61 = -24

8 = -24 is incorrect.

So it has no solution.
