Answer:

the slope, m, is -6

Step-by-step explanation:

One of the most commonly used equations for a straight line is y = mx + b, where m is the slope and b is the y-intercept.

Comparing  y=4-6x to y = b + mx, we see that the slope, m, is -6 and the y-intercept, b, is 4.

The slope of the line y = 4 - 6x is -6, which shows that for every increase of 1 in the x-coordinate, the y-coordinate decreases by 6.

The equation is given as follows:

y = 4 - 6x

As we know that the equation is in slope-intercept form, y=mx+b.

Here, m is the slope and b is the y-intercept.

As per the question, the y-intercept is 4, which means the line crosses the y-axis at (0,4).

The slope, -6, tells us that for every increase of 1 in the x-coordinate, the y-coordinate decreases by 6.

Thus, the slope of the line y = 4 - 6x is -6.

Answer: 2√3

Step-by-step explanation: To divide √60 by √5, we simply divide the numbers that are inside the radicals.

Since the quotient of 60 divided by 5 is 12,

the square root of 60 divided by the square root of 5 is √12.

However, we can simplify the square root of 12.

The √12 breaks down into 4 · 3 and 4 breaks down into 2 · 2.

The 2's match up, so a 2 comes outside of the radical.

Since the 3 doesn't pair up, it stays inside.

So our answer is 2√3.

Final answer:

The simplification of [tex]\sqrt{60}/\sqrt{5[/tex] results in [tex]2\sqrt{3,[/tex] by combining the square roots into one and then simplifying the inner value.

Explanation:

The question asks for the simplification of the expression which is the square root of 60 divided by the square root of 5. To simplify this expression, one can utilize the property of square roots that allows the division within a single square root function. Here’s a step-by-step explanation:

Write the expression as [tex]\sqrt{60}/\sqrt{5[/tex]

Combine the square roots using the property[tex]\sqrt{(a)}/\sqrt{(b)} = \sqrt{(a/b),[/tex] giving[tex]\sqrt{60}/\sqrt{5[/tex]

Simplify 60/5 to get 12.

Now take the square root of 12, which is not a perfect square. However, we can express 12 as the product of 4 (which is a perfect square) and 3 (4 * 3 = 12).

Finally, we write the expression  [tex]\sqrt{4} * \sqrt{3,[/tex] which simplifies to [tex]2\sqrt{3,[/tex]

Thus, the simplified form of [tex]\sqrt{60}/\sqrt{5[/tex] is [tex]2\sqrt{3,[/tex], which cannot be simplified any further as [tex]\sqrt{3[/tex] is an irrational number and does not have a precise decimal representation.

It is always important to remember that when rounding is necessary, you should round the result up if the digit following the last significant digit is 5 or greater, and round it down if it is less than 5.

Answer:

Number of movies that can be shown = 2

Step-by-step explanation:

Given:

Movie night duration = 4 hours

Duration of each movie = 1.75 hours

Time given for eating popcorn = 0.5 hours

Time alloted for movies (excluding popcorn time) = 4 - 0.5 = 3.5 hours.

Number of movies that can be shown = [tex]\frac{Total\ time\ alloted\ for\ movie}{Time\ for\ 1\ movie}=\frac{3.5}{1.75}= 2[/tex]

To determine the number of movies that can be watched, an equation M*X <= T can be formulated where M is the length of the movie, X is the number of movies, and T is the total time available. To find X, divide T by M. This works when the time for each movie is the same.

Without the actual graphic novel frame, it's hard to provide a specific equation. However, I can give you an example on how to approach this situation. Let's assume each movie is of length 'M' minutes and you have a total of 'T' minutes available for watching movies.

,

Let 'X' be the number of movies you can watch. You would write this as a mathematical equation like this: M*X <= T. This equation states that the total time spent watching movies should be less than or equal to the total time available.

,

To solve the equation, you would divide both sides of the equation by 'M'. The result will be X <= T/M. If you know the values of 'M' and 'T', you can plug them in here to get the maximum number of movies you can watch.

Divide the total number of cans by 6.

42 / 6 = 7

He bought 7 six packs.

Final answer:

Victor bought 7 six-packs of soda.

Explanation:

To find the number of six-packs of soda Victor bought, divide the total number of cans by 6. In this case, Victor bought 42 cans in total, so dividing 42 by 6 gives us 7. This means Victor bought 7 six-packs of soda.

1. Set up a ratio:

7 tagged / 350 fish = 250 tagged / x fish

Solve for x:

x = (350 * 250) / 7

x = 12,500 fish

2. Divide number of boys by the population ratio:

450 / 2/5 =  (450 *5) /2 = 2250 / 2 = 1125 total students.

3.  4 quarters = $1, so they have 24 quarters total.

The ratio 3:5 means for every 3 quarters there are 5 dimes.

24 quarters / 3 = 8

8 x 5 = 40 dimes.

(1)  The population of fish in the False river is 12500.

(2) There are 1125  total number of students in the school .

(3) There are 40 dimes in the bag.

(1) Number of fish tagged by Louisiana biologists =  250

On the next day a sample was collected from the False river

The number of fish in the sample = 350

Number of tagged fish in the sample =  7

Let the population of fish in the False river  = P

Takin the ratio we can

[tex]\rm \dfrac{7}{350}= \dfrac{250}{P} \\\\P = (250)(350)/(7)\\P = 12500[/tex]

So the population of fish in the False river = 12500

(2) The number of boys in the school = 450

Let the total number of students in the  school be B

According to the given condition

[tex]\rm \dfrac{2}{5}\times B = 450\\\\B = (450\times 5) /2 \\B = 2250/2 =1125[/tex]

So the total number of students in the school = 1125

(3) Let the number of dimes in the bag be x

According to the given condition we can write

[tex]\rm \dfrac{Number\; of\; quarters }{Number\; of\; dimes } = \dfrac{3}{5} ........(1)[/tex]

Also  it is given that there are $6 in quarters in the bag.

$1 = 4 quarters

So $6 has  [tex]\rm 4\times 6 = 24 \; quarters[/tex]

So we can put this value in equation (1)

[tex]\dfrac{24}{x} =\dfrac{3}{5} \\\\x = 40 dimes[/tex]

So we can conclude that there are 40 dimes in the bag.

Answer:

[tex]radius=5\ cm[/tex]

Step-by-step explanation:

Let r be the radius of the circle and A be the area of the circle.

Given:

[tex]r_{1} = 2\ cm, A_{1}=12.566\ cm^{2}[/tex]

And [tex]r_{2} = ?, A_{2}=78.54\ cm^{2}[/tex]

The area of a circle is directly  proportional to the square of its  radius.

A ∝ [tex]r^{2}[/tex]

[tex]A = kr^{2}[/tex]-----------(1)

Where k is the constant of proportionality

Find constant value by substituting [tex]r_{1} = 2\ cm, A_{1}=12.566\ cm^{2}[/tex]

in equation 1.

[tex]A = kr^{2}[/tex]

[tex]A_{1}=k(r_{1})^{2}[/tex]

[tex]12.566=k\times 2^{2}[/tex]

[tex]12.566=k\times 4[/tex]

[tex]k=\frac{12.566}{4}[/tex]

[tex]k=3.141[/tex]

Find [tex]r_{2}[/tex] by substituting k and [tex]A_{2}[/tex] value in equation 1.

[tex]A = kr^{2}[/tex]

[tex]A_{2}=k(r_{2})^{2}[/tex]

[tex]12.566=3.141\times (r_{2})^{2}[/tex]

[tex](r_{2})^{2}=\frac{78.54}{3.141}[/tex]

[tex](r_{2})^{2}=25.004[/tex]

where: 25.004 ≅ 25

[tex](r_{2})^{2}=25[/tex]

[tex]r_{2}=\sqrt{25}[/tex]

[tex]r_{2}=5\ cm[/tex]

Therefore; the radius of the circle is 5 cm.

Final answer:

The radius of a circle with an area of 78.54 cm² is approximately 4 cm, after setting up a proportion with a known circle area and solving for the unknown radius.

Explanation:

The area of a circle is given by the formula A = πr², where A is the area and r is the radius of the circle. Given that a circle with a radius of 2 cm has an area of 12.566 cm², we set up a proportion to find the radius of a circle with an area of 78.54 cm²:

(12.566 cm²) / (2 cm)² = (78.54 cm²) / r².

Solving for r, we find r² = (78.54 cm²) × (2 cm)² / (12.566 cm²).

After calculation, we get r approximately equal to 4 cm, rounding to the nearest whole number.

To find the area of the clock face with a 4-meter radius, use the area formula for a circle, which gives approximately 50.265482 m². Rounded to the nearest square meter, the clock face area is about 50 m².

Explanation:

The clock face in a famous clock tower has a radius of 4 meters, and we want to find the area of the clock face to the nearest square meter. To do this, we use the formula for the area of a circle, which is A = πr², where A is the area and r is the radius of the circle.

Plugging in the radius of the clock face:

A = π(4 m)² = π(16 m²) ≈ 50.265482 m²

However, since we want the answer to the nearest square meter, we round this to:

A ≈ 50 m²

Final answer:

The area of the clock face with a radius of 4 meters is approximately 50 square meters when rounded to the nearest square meter.

Explanation:

The area of a clock face in a famous clock tower, given its radius is 4 meters, can be calculated using the formula for the area of a circle, which is [tex]A = πr^2[/tex] where A is the area and r is the radius of the circle. In this case, substituting the radius of 4 meters into the formula gives us[tex]A = π(4m)^2 = π16πm^2.[/tex] To give an answer to the nearest square meter, we use the value π = 3.14, resulting in [tex]A = 16(3.14)m^2 = 50.24m^2[/tex], which rounds to 50 m².

By dividing 452 pictures of dogs by 4, we find that each of the 4 equal groups has 113 pictures. The division process involves using place value and the standard algorithm for long division.

To find out how many pictures of dogs are in each group, we need to divide the total number of pictures by the number of groups. The question states there are 452 pictures of dogs and these are divided into 4 equal groups. We can use long division to solve this.

Step-by-Step Solution:

Write down the division: 452 ÷ 4.

Start by looking at the hundreds place in 452. There are 4 hundreds in 452. Since 4 divided by 4 is 1, we put 1 in the hundreds place of the quotient.

Multiply the divisor (4) by the quotient (100) to get 400.

Subtract 400 from 452 to get 52.

Now, look at the tens place in 52. There are 5 tens in 52, and since 5 divided by 4 is 1 with a remainder, we put 1 in the tens place of the quotient and have a remainder of 12 after subtracting 40 (1 x 4 tens) from 52.

Next, look at the ones place in 12. There are 12 ones, and since 12 divided by 4 is 3, we put 3 in the ones place of the quotient.

After placing 3 in the ones place, we have no remainder, which means the division is complete and the quotient is 113.

Therefore, each group has 113 pictures of dogs.

Answer:

C = 6.75n + 50

Step-by-step explanation:

The equation for the cost of renting the party room can be written in the form;

C= mn+k ......i

Where C = cost

n = number of people

Substituting the 2 cases into the equation we have,

Case 1

117.5 = 10m + k ......1

Case 2

151.25 = 15m + k .....2

Subtracting eqn 1 from 2 we have

151.25 - 117.50 = 15m - 10m

5m = 33.75

m = 33.75/5 = 6.75

Substituting m = 6.75 into eqn 1, we have

117.50 = 10(6.75) + k

k = 117.5 - 67.50

k = 50

Therefore, rewriting the eqn i, we have

C = 6.75n + 50

To find the exact values of cos(0), csc(0), and tan(0) given a point on the terminal side of 0, we can use the coordinates of the point to determine the values of the trigonometric functions.

To find the exact values of cos(0), csc(0), and tan(0) given that (-3,-2) is a point on the terminal side of 0, we can use the coordinates of the point to determine the values of the trigonometric functions.

First, we can find the value of cos(0) by dividing the x-coordinate (-3) by the distance from the origin, which is sqrt((-3)^2+(-2)^2). Therefore, cos(0) = -3 / sqrt(13).

Next, we can find the value of csc(0) by dividing 1 by the y-coordinate (-2). Therefore, csc(0) = 1 / -2 = -1/2.

Finally, we can find the value of tan(0) by dividing the y-coordinate (-2) by the x-coordinate (-3). Therefore, tan(0) = -2 / -3 = 2/3.
