You spend 60 on clothes and buy 3 dvd movies. your friend spends nothing on clothes and buys 8 dvd movies. you both spend the same amount of money. how much does each dvd movie cost?

Answers

Answer 1

Each dvd cost $7.50 how? Your friends buy 8 dvd's and in total is 60, you want to divide 60 from 8 and find that it's 7.50 and then multiply 8 to 7.50 and it should be 60. Hope this helps!!

Answer 2

Each DVD movie costs $12. This is calculated by setting up and solving an equation where the total spending on clothes and 3 DVDs equals the spending on 8 DVDs, as both parties spent the same amount.

To find out how much each DVD movie costs, we need to set up an equation based on the given information. You spent $60 on clothes and bought 3 DVD movies, while your friend spent $0 on clothes and bought 8 DVD movies. It is given that both of you spent the same amount of money. Let's denote the cost of each DVD movie as x.

The total amount you spent is the cost of the clothes plus the cost of the 3 DVD movies, which can be expressed as $60 + 3x. Your friend spent the cost of the 8 DVD movies, which is 8x. Since both amounts are equal, we have:

60 + 3x = 8x

Solving this equation for x:

Subtract 3x from both sides: 60 = 5xDivide both sides by 5: x = $12

Therefore, the price of each DVD movie is $12.

Fernando is going to draw a marble from the bag, replace it, and then draw another marble. What is the probability that Fernando will get a green or blue marble on the first draw and a pink on the second draw?

(3 green, 4 yellow, 5 blue, 8 pink)

1.) 4/5
2.) 4/25
3.) 3/100

Answers

The answer is actually the second choice 4/25 hope this helps...

Answer: The correct option is (2) [tex]\dfrac{4}{25}.[/tex]

Step-by-step explanation: Given that there are 3 green, 4 yellow, 5 blue and 8 pink marbles in a bag. Fernando is going to draw a marble from the bag, replace it, and then draw another marble.

We are to find the probability that Fernando will get a green or blue marble on the first draw and a pink on the second draw.

Let, S be the sample space for the experiment of drawing a marble from the bag.

Then, n(S) = 3 + 4 + 5 + 8 = 20.

Let E denotes the event of drawing a green or blue marble and F denote the event of drawing a pink marble.

Then, we have

n(E) = 3 + 5 = 8 and n(F) = 8.

Since the second marble is drawn after replacing the first marble,

so the required probability of Drawing a green or blue marble on the first draw and a pink marble on the second draw is

[tex]P\\\\=P(E)\times P(F)\\\\\\=\dfrac{n(E)}{n(S)}\times \dfrac{n(F)}{n(S)}\\\\\\=\dfrac{8}{20}\times\dfrac{8}{20}\\\\\\=\dfrac{4}{25}.[/tex]

Thus, the required probability is [tex]\dfrac{4}{25}.[/tex]

The local weather report states that the probability that it will snow today is 20% and the probability that it will snow tomorrow is 40%. Which of the following is a true statement?
A.
It is not very likely that it will snow both today and tomorrow.

B.
It is very likely that it will snow both today and tomorrow.

C.
It is impossible that it will snow both today and tomorrow.

D.
It is certain that it will snow both today and tomorrow.

Answers

Final answer:

The probability of it snowing both today and tomorrow is 8%, based on the given probabilities for individual days. Therefore, the most accurate statement is that it's not very likely for it to snow on both days.

Explanation:

The question revolves around understanding the concept of probability. In the context of probability, you multiply the probabilities of two independent events (like it snowing on two different days) to get the probability of both occurring.

To find out if it will snow both today and tomorrow, we multiply the probability it will snow today (20% or 0.2) by the probability it will snow tomorrow (40% or 0.4). This gives us a probability of 0.08 or 8%, which means that it's not very likely that it will snow both today and tomorrow.

So, the correct answer would be Option A: It is not very likely that it will snow both today and tomorrow.

5-sided polygon on a coordinate plane with vertices F, N, S, C, W. Point f is at (negative 4, negative 2), point N is at (2, 4), point s is at (5, negative 2), point c is at (5, negative 4), and point w is at (negative 4, negative 4)

Answers

Step 1) Draw a line from point F to point S. A rectangle forms (rectangle FSCW)

Step 2) Find the area of this rectangle. The area is 18 square units because it is 2 units high and 9 units across (9*2 = 18). You can count out the spaces or you can note how we go from x = -4 to x = 5 so subtracting the values gives -4-5 = -9 which has an absolute value of 9.

Step 3) Find the area of triangle FSN. The base is 9 units and the height is 6 units (count out the spaces or subtract y values). So the area is A = b*h/2 = 9*6/2 = 54/2 = 27

Step 4) Add up the area of the rectangle to the area of the triangle: 18+27 = 45

Final Answer: 45 square units

note: another way to find the answer is to find the area of rectangle WABC where point A is at (-4,4) and point B is at (5,4). Then subtract off the triangular areas of AFN and BNS

In this exercise we have to use the knowledge of polygon area to calculate the area of a trapezoid, in this way we find that:

[tex]45 units[/tex]

So find the area of this rectangle, this area will be:

[tex]9*2 = 18[/tex]

Find the area of triangle FSN, this area will be:

[tex]A = b*h/2 = 9*6/2 = 54/2 = 27[/tex]

Sum all the areas will be:

Convert. If necessary, round to the nearest tenth. (Recall: 1 mi ≈ 1.61 km) km/h ~ 10 mi/h

Answers

16.1 km/h because all you're really doing is moving a decimal place back 1.0 becomes 10 so 1.61 becomes 16.1

Answer:

10 mile per hour = 16.1 kilometers per h our

Step-by-step explanation:

We know that

1 mile = 1.61 kilometers

We are supposed to convert speed given in miles per hour (mph) to kilometers per hours (kmph)

In order to do so ,

1 mile = 1.61 kilometers

1 mile per hour = 1.61 kilometers per hour

Multiplying both sides by 10 we get

10 miles per hour = 1.61 *10 kilometers per hour

10 miles per hour = 16.1 kilometers per hour

Hence our speed in kilometers per hour is 16.10 kmph

A certain number of bacteria are in a petri dish. If the growth rate is 2.7 percent per hour, how many hours will it take the bacteria to double in number?

Answers

Final answer:

Using the rule of 70, which states that the doubling time in hours is equal to 70 divided by the growth rate percentage, it will take approximately 25.93 hours for the bacteria to double in number at a growth rate of 2.7 percent per hour.

Explanation:

To calculate the time it will take for the bacteria to double in number with a growth rate of 2.7 percent per hour, we can use the rule of 70. The rule of 70 states that we can find the doubling time by dividing 70 by the percentage growth rate.

Doubling time = 70 ÷ growth rate percentage = 70 ÷ 2.7 ≈ 25.93

Therefore, it will take approximately 25.93 hours for the bacteria to double in number.

A basketball is thrown upwards. The height f(t), in feet, of the basketball at time t, in seconds, is given by the following function:

f(t) = -16t^2 + 16t + 32

Which of the following is a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground?

A: 0.5 < t < 1
B: 0.5 < t < 2
C: 1 < t < 2
D: 1 < t < 1.5

Answers

To solve this we are going to find the maximum eight of the parabola first. Since the parabola is opening downwards, the maximum height of the ball will be the t-coordinate of its vertex.
Remember that to find the vertex [tex](h,k)[/tex] of a parabola of the form [tex]a x^{2} +bx+c[/tex] we use the vertex formula: [tex]h= \frac{-b}{2a} [/tex], and then, we evaluate our function at [tex]h[/tex] to find [tex]k[/tex].
We can infer for our parabola that [tex]a=-16[/tex] and [tex]b=16[/tex], so lets replace those values in our formula:
[tex]h= \frac{-b}{2a} [/tex]
[tex]h= \frac{-16}{2(-16)} [/tex]
[tex]h= \frac{-16}{-32} [/tex]
[tex]h=0.5[/tex]
Now we now that the ball reaches its maximum height in 0.5 seconds.

Next, we are going to determine how long it takes for the ball to hit the ground. To do that we are going to set the time [tex]f(t)[/tex] equal to zero and solve for [tex]t[/tex]:
[tex]0=-16t^2+16t+32[/tex]
[tex]16t^2-16t-32=0[/tex]
[tex]16(t^2-t-2)=0[/tex]
[tex]t^2-t-2=0[/tex]
[tex](t+1)(t-2)=0[/tex]
[tex]t=-1[/tex] or [tex]t=2[/tex]

Since time cannot be negative, the answer is [tex]t=2[/tex]

We can conclude that a reasonable domain of the graph of the function when the basketball falls from its maximum height to the ground is B: 0.5 < t < 2

What is the volume of a sphere if the radius is 9?

Answers

V=4/3pi r^3
Answer is 3053.63

Answer: [tex]Volume = 972\pi units^{3}[/tex]

Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere.

[tex]Volume = \frac{4}{3} \pi r^{3}[/tex]

Notice that our sphere has a radius of 9 units so we can plug 9 into our formula.

[tex]Volume = (\frac{4}{3})(\pi)(9 units)^{3}[/tex]

Now, let's simplify the exponent. 9 units³ is equal to 9 units × 9 units × 9 units or 729 units³.

[tex]Volume = (\frac{4}{3}) (729 units^{3}) (\pi)[/tex]

Notice that we can cross cancel [tex]3[/tex] in [tex]\frac{4}{3}[/tex] and [tex]729[/tex] to [tex]1[/tex] and [tex]243.[/tex]

[tex]Volume = (4) (243units^{3}) (\pi)[/tex]

QS is the perpendicular bisector of PR solve for x

Answers

2x - 20 = 70 - x

3x - 20 = 70

3x = 90

x = 30

Final answer:

The term 'perpendicular bisector' means QS cuts PR into two equal parts at a 90-degree angle. If PR is '2x', then each half is 'x'. To solve for x, we would need data about the lengths of the line segments.

Explanation:

Given that QS is the perpendicular bisector of PR, it implies two things. Firstly, QS intersects PR at a 90-degree angle. Secondly, QS splits PR into two equal segments. So, if PR is represented as '2x', then PQ and QR are both 'x'.

Unfortunately, missing information prevents a specific solution for x. We'd need additional data about the lengths of these line segments to solve the equation for x. For instance, if PR = 10, then '2x = 10' which gives us 'x = 5'.
