The outer edge of the dime is about 55mm. What is the approximate length of the radius?

Answers

Answer 1

To find the approximate length of the radius, you will use the formula for finding the circumference of a circle and solve for the radius (r).

C = 2 x pi x r
55 = 2 x 3.14 x r
55 = 6.28 x r
6.28 6.28
r = 9.2 mm

The approximate radius is 9.2 mm.

Amanda owns a clothing store that sells graphic t-shirts. n is the number of shirts she sells each month. the revenue function of her store is r = 25n. the cost function of her store is c = 10n + 900. using your calculator, what is the break-even point of amanda's store?

Answers

The break-even point will be attained when the revenue is equal to the cost. That is
[tex]25n=10n+900[/tex]
[tex]25n-10n=900[/tex]
[tex]15n=900[/tex]
[tex]n=60[/tex]

The break-even point is attained when n equals 60.

Answer:

n = 60 shirts

Step-by-step explanation:

The break-even point is the point where revenue is equal to cost. This means we take the equation for revenue, r = 25n, and set it equal to the equation for cost, c = 10n + 900:

25n = 10n + 900

Subtract 10n from each side:

25n - 10n = 10n + 900 - 10n

15n = 900

Divide both sides by 15:

15n/15 = 900/15

n = 60

The probability that the Cubs win their first game is 1/3. The probability that the Cubs win their second game is 3/7. What is the probability that the Cubs win games?

Answers

We need to multiply these probabilities up. Indeed, we are talking about independent events. Then, the final answer is 1/3 * 3/7=1/7

The correct answer is:

1/7.

Explanation:

The two events, the Cubs winning their first game and the Cubs winning their second game, are independent. This is because the Cubs winning their first game does not affect the probability of the Cubs winning their second game.

Since the events are independent, to find the probability that both events occur, multiply the probabilities:

1/3(3/7) = (1*3)/(3*7) = 3/21 = 1/7

Jesse made a model of a mountain range for class. to do this, he bought a cylinder of cardboard and cut it into three cones. each cone is 5 inches tall and has a diameter of 4 inches. what was the volume of the original cylinder jesse bought in terms of \piπ?

Answers

By definition, the volume of the cone is given by:
V = (1/3) (π) (r ^ 2) (h)
Substituting values we have:
V = (1/3) (π) ((4/2) ^ 2) (5)
V = (20/3) (π)
Then, the volume of the cylinder is:
Vc = 3 * V
Vc = 3 * (20/3) (π)
Vc = 20π
Answer:
the volume of the original cylinder jesse bought is:
Vc = 20π

The volume of the original cylinder that Jesse bought is 20π cubic inches.

To find the volume of the original cylinder Jesse bought, we need to use the volume formula for a cylinder:

V = πr²h

First, we need to find the volume of each cone using the formula:

Volume of a cone = (1/3)πr²h

Given:

Height(h) of each cone = 5 inchesDiameter of each cone = 4 inches, so the radius(r) = 4/2 = 2 inches

Volume of one cone:

V_cone = (1/3)π(2)²(5) = (1/3)π(4)(5) = (20/3)π cubic inches

Total volume of three cones:

V_total_cones = 3 × (20/3)π = 20π cubic inches

Since the volume of the cylinder equals the total volume of the cones:

V_cylinder = 20π cubic inches

In which quadrant of the coordinate plane is (-2a - 3, -3b - 5), if a = -3 and b = 3?

Answers

(-2a - 3, -3b - 5), if a = -3 and b = 3

- 2a - 3 = -2(-3) - 3 = 6 - 3 = 3
-3b - 5 = -3(3) - 5 = -9 - 5 = -14

(3, -14)

answer:
quadrant IV

After substituting a = -3 and b = 3 into the point (-2a - 3, -3b - 5), we get the point (3, -14), which lies in the fourth quadrant of the coordinate plane.

To determine in which quadrant of the coordinate plane the point (-2a - 3, -3b - 5) is located, we substitute the values a = -3 and b = 3 into the coordinates. First, for the x-coordinate we have:

-2(-3) - 3 = 6 - 3 = 3

And for the y-coordinate:

-3(3) - 5 = -9 - 5 = -14

The resulting point is (3, -14), which is located in the fourth quadrant because the x-value is positive and the y-value is negative.

Given f(x)=x2+14x+40 .

Next, complete the square:

f(x)=x^2+14x+ 49 - 49 +40 = (x+7)^2 - 9

Write this in the form y = (x+7)^2 - 9 or y + 9 = (x+7)^2
Comparing this result to y = a(x-h)^2 + k, we see that h = -7 and k=-9

In vertex form, the equation is y + 9 = (x+7)^2 and the vertex is at (-7, -9).

A total of 300 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adults tickets sold. How many adult tickets were sold?

Answers

75 Adults
225 Students

You can get this information using this system of equations:

x + y = 300
x - 3y = 0

By setting up and solving an equation, it was determined that 75 adult tickets were sold for the school play.

To solve the problem of determining how many adult tickets were sold for the school play, we can set up an equation. Let's represent the number of adult tickets sold as A, and since the number of student tickets sold was three times that of adult tickets, we can express the student tickets sold as 3A. We know the total tickets sold were 300, so the equation to represent this scenario is:

A + 3A = 300

Combining like terms, we get:

4A = 300

Dividing both sides of the equation by 4 to solve for A gives us:

A = 300 / 4

A = 75

Therefore, 75 adult tickets were sold.

Use Euler’s Formula to find the number of edges in a polyhedron with seven faces: two pentagons and five rectangles.

Answers

To determine the number of edges in a polyhedron with seven faces, two being pentagons and five being rectangles, you apply Euler's formula, resulting in a total of 15 edges.

To find the number of edges in a polyhedron with seven faces using Euler's formula, which is V - E + F = 2, we first need to determine the number of vertices (V) and faces (F) of the polyhedron.

Given that the polyhedron has two pentagons and five rectangles, we can calculate the total number of vertices. Each pentagon has 5 vertices and each rectangle has 4, but since rectangles share sides, some vertices will be counted twice.

Therefore, for the rectangles, we should calculate the vertices as if there were four distinct ones and then subtract the overlaps. Assuming all rectangles share exactly one side with its adjacent, we would have 4 vertices for each rectangle minus 2 for each shared side, resulting in 2 vertices per rectangle.

With five rectangles, that's 10 vertices, plus the 10 from the two pentagons, we get 20 vertices in total. Now, we apply Euler's formula: V - E + F = 2, substituting the values:

E = V - F + 2
E = 20 - 7 + 2
E = 15

Therefore, the polyhedron has 15 edges. .

Answers

The value of m must be greater than the value of n. When you multiply the binomials, the middle term is the result of combining the outside and inside products. So, bx = –nx + mx, or bx = (–n + m)x. This means that b = –n + m. When adding numbers with opposite signs, you subtract their absolute values, and keep the sign of the number having the larger absolute value. Since b is positive, mmust have the larger absolute value.

Maggie only wore sandals tracker on two of the days that she trained so from her fitness trackers she verified that on the third day she biked 20 miles and on the eighth day she biked 35 miles use these two data points to determine the equation of the line best of fit set for Maggie’s data

Answers

We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that on the eighth day she biked 35 miles, so our second point is (8,35).

To relate our two point we are going to use the slope formula: [tex]m= \frac{x_{2}-x_{1}}{y_{2}-y_{1}} [/tex]
We can infer form our points that [tex]x_{1}=3[/tex], [tex]y_{1}=20[/tex],[tex]x_{2}=8[/tex], and [tex]y_{2}=35[/tex]. so lets replace those values in our slope formula:
[tex]m= \frac{35-20}{8-3} [/tex]
[tex]m= \frac{15}{5} [/tex]
[tex]m=3[/tex]

Now that we have the slope, we can use the point-slope formula determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: [tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-20=3(x-3)[/tex]
[tex]y-20=3x-9[/tex]
[tex]y=3x+11[/tex]

We can conclude that the equation of the line that best fit the set for Maggie’s data is [tex]y=3x+11[/tex].

Christine runs 7 miles in 60 minutes. at the same rate, how many miles would she run in 24 minutes?

Answers

Let x = the unknown amount of miles she would run. We are going to set up a proportion.

[tex] \frac{7 miles}{60 min} = \frac{x miles}{24 min} [/tex]

Now we are going to cross-multiply and solve for x.

60x = 7(24)
60x = 168
x = 168 / 60
x = 2.8

Christine runs 2.8 miles in 24 minutes.

Final answer:

Christine would run approximately 2.8 miles in 24 minutes at the same rate she runs 7 miles in 60 minutes.

Explanation:

To find out how many miles Christine would run in 24 minutes, we can set up a proportion. We know that Christine runs 7 miles in 60 minutes, so we can write the proportion as:

7 miles / 60 minutes = x miles / 24 minutes

Now, we can cross-multiply and solve for x:

7 * 24 = 60 * x

168 = 60x

x = 168 / 60

x ≈ 2.8 miles

So, her speed would be 7/60 = 0.1167 miles per minute. Now, to find out the distance she would cover in 24 minutes at this speed, we multiply her speed per minute by 24 minutes. So, 0.1167 * 24 = approximately 2.8 miles. Therefore, at the same rate, Christine would run about 2.8 miles in 24 minutes.

Prove that x²+6x+18 is always greater than

Answers

One way to solve this would be to graph both y=x^2+6x+18 and y=2 - 1/x. If the graph of the polynomial is always higher up (above) the graph of y=2-1/x, that alone is sufficient cause to state that the poly is always greater than 2-1/x.

You could also do this algebraically: write the inequality

x^2+6x+18 > 2 -1/x. This can be rewritten as x^2+6x+18-2+1/x > 0, or
x^2+6x+16+1/x > 0

Try x=-3. Then 9-18+16-1/3 = 6 2/3, which is greater than 0.

Or you could graph x^2+6x+16+1/x by hand or on a calculator. Is the graph always above the x-axis? If so, x²+6x+18 is always greater than 2-1/x.
