Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.

Step-by-step explanation:

Shooters = 1 dollar is 60 cents

60 divided by 5 = 12

Red = 60 divided by 3

= 20

Multicolored = 60 x 5 because 1 for 5

= 300

Answer:

1584 cu in.

Step-by-step explanation:

Since the volume varies jointly with the radius and height we have an equation V = kr^2h where k is the constant of variation

28 = 2^2(7)k = 28k

k = 1

Now V = r^2h

V = (12)^2(11) = 144(11) = 1584 cu in.

Step-by-step explanation:

a) The circumference of the circle is given by ...

  C = πd

  C = (3.14)(5.5 mi) = 17.27 mi

The distance around the lake is about 17.27 miles.

__

b) The area is given by ...

  A = πr^2 . . . . . where r = d/2

  A = (3.14)(2.75^2) ≈ 23.75 . . . . square miles

The surface area of the lake is about 23.75 square miles.

Answer:

  (a)  an = 2n -1

  (b)  an = n(n +1)/2

  (c)  an = n^2

Step-by-step explanation:

(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...

  an = a1 +d(n -1)

  an = 1 + 2(n -1)

  an = 2n -1

__

(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.

The first few terms and differences are ...

  sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)

  first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)

  2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)

There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:

  an = a1 +(n -1)(d1 +(n -2)/2(d2))

For the values we have, this gives our general term as ...

  an = 1 + (n -1)(2 +(n -2)/2(1))

  an = n(n +1)/2

__

(c) The general term in the sequence of square numbers is simply the square of the term number:

  an = n²

_____

* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.

The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.

[tex] \tt : \implies \dfrac{x+2}{x-2} + \dfrac{x-2}{x+2} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{(x+2)(x+2) + (x-2)(x-2)}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{(x+2)^{2} + (x-2)^{2}}{(x-2)(x+2)} = \dfrac{5}{6}[/tex]

Now, we know that :

[tex] \tt : \implies \dfrac{x^{2}+2^{2}+ 2 \times x \times 2 + x^{2}+2^{2} - 2 \times x \times 2 }{x^{2}-2^{2}} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{x^{2}+ 4 + \cancel{4x} + x^{2}+ 4 - \cancel{4x}}{x^{2}-4} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{x^{2} + x^{2} + 4 + 4}{x^{2}-4} = \dfrac{5}{6}[/tex]

[tex] \tt : \implies \dfrac{2x^{2} + 8}{x^{2}-4} = \dfrac{5}{6}[/tex]

By cross multiply :

[tex] \tt : \implies (2x^{2} + 8)6= 5(x^{2}-4)[/tex]

[tex] \tt : \implies 12x^{2} + 48 = 5x^{2}-20[/tex]

[tex] \tt : \implies 12x^{2} + 48 - 5x^{2} + 20 = 0[/tex]

[tex] \tt : \implies 7x^{2} + 68 = 0[/tex]

[tex] \tt : \implies 7x^{2} + 0x + 68 = 0[/tex]

Now, by comparing with ax² + bx + c = 0, we have :

By using quadratic formula :

[tex] \large \underline{\boxed{\bf{x = \dfrac{-b \pm \sqrt{b^{2} - 4ac}}{2a}}}}[/tex]

[tex] \tt : \implies x = \dfrac{-(0) \pm \sqrt{(0)^{2} - 4(7)(68)}}{2(7)}[/tex]

[tex] \tt : \implies x = \dfrac{0 \pm \sqrt{0 - 1904}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \sqrt{- 1904}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \sqrt{2\times 2\times 2\times 2\times 7\times 17}}{14}[/tex]

[tex] \tt : \implies x = \dfrac{\pm \cancel{2} \times 2\sqrt{7\times 17}}{\cancel{14}}[/tex]

[tex] \tt : \implies x = \dfrac{\pm2\sqrt{119}}{7}[/tex]

[tex] \large \underline{\boxed{\bf{x = \dfrac{\pm 2\sqrt{119}}{7}}}}[/tex]

Hence value of [tex] \bf x =\dfrac{\pm 2\sqrt{119}}{7}[/tex]

Answer:

110

Step-by-step explanation:

They are equal to each other.

23x-5= 21x +5

2x = 10

x = 5

21(5) +5 = 110°

23(5) -5 = 110°

So it works. Angles are 110°

119 + 1 + 3 + 5 =            add that if i am wrong sorry but have  a nice day <3

Answer:

The circumference of the CD is approximately 38 cm

Step-by-step explanation:

The circumference of the CD can be seen as the distance around the CD.

The word "circumference"  is used to describe the perimeter of circular objects.

To find an approximate value of the circumference of the CD, we will use this formula.

Circumference = π × diameter

let us take π to be = 3.142

∴ circumference = 3.142 × 12 = 37.6991 cm

we can round this up to teh nearest tenth as 38cm

Answer:

See explanation below

Step-by-step explanation:

This is actually pretty easy to explain, and we all need to do is work with fractions.

So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.

Let's go with each ingredient, one by one:

Chicken broth 2 2/3 cups:

In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)

2 2/3 = (3*2) + 2 / 3 = 8/3 of cups

8/3 * 2/3 = 16/9 cups of chicken.

But to do this better, let's convert this into a mix fraction:

16 : 9 = 1  and the rest is 7 so:

Chicken 1 1/2 cups:

We'll do the same thing as before:

1 1/2 = (2*1) + 1 / 2 = 3/2 of cups

3/2 * 2/3 = 1

3/4 cups or rice:

3/4 * 2/3 = 1/2

Hope this helps

The point after which shape A is rotated 180 degrees is (-1, 0).

It is the movement of the shape in the left, right, up, and down directions.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

Shape A is in the point (1, 0).

This means,

Shape A is in the First Quadrant.

Now,

Shape A is rotated 180 degrees.

If rotated clockwise or counterclockwise shape A will be in the same quadrant.

This means,

Shape A will be in the Third quadrant.

Now,

First quadrant coordinates = (x, y)

Third quadrant coordinates = (-x, -y)

So,

(x, y) → (-x, -y)

(1, 0) → (-1, 0)

Thus,

Shape A will be in (-2, 0).

the angle would be a 90° angle

========================================================

Explanation:

At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.

Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.

Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5

The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.

The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.

Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24

The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.

So, (5/24)*360 = 75 degrees is the angle measure in this diagram.

Answer:

triangle A= 1/2bh

1/2(18)(14)= 126

semi circle 3.14(9)^2 divided by 2 = 127.17

Triangle Area plus semi circle Area = 126+127.17= 253.17

Problem 3

Explanation: The angles opposite the congruent sides, are congruent angles. We consider these the base angles. This triangle is isosceles.

==================================================

Problem 4

Explanation:

Refer to the diagram below. Note how I've added in the variable y and marked another angle as 53 degrees which is one of the base angles of the left triangle. The base angles of the triangle on the right are y degrees each. Also, note the vertical angles both are y.

For the left triangle, the three angles add up to 180 which means we can solve for y to go from 53+53+y = 180 to y = 74

Then the interior angles of the triangle on the right has the three angles (y,y,x) add to 180 as well. So we have y+y+x = 180 which turns into 74+74+x = 180. That solves to x = 32

==================================================

Problem 5

Explanation:

Refer to the diagram below. I've added another base angle x, and the angle 90-x is complementary to this. This is because the two pieces must add to 90.

For the triangle on the bottom, the two base angles 74 and 74, add to the third angle 90-x and we would get 180. So we solve 74+74+(90-x) = 180 to get x = 58

Answer:

3. x = 47

4. x = 32
