The value of [tex]sin100.sin120.sin140.sin160[/tex] is [tex]0.1875[/tex]

Step-by-step explanation:

To find the value of [tex]sin100.sin120.sin140.sin160[/tex], let us find the value of each angle.

The value of [tex]sin100=0.9848[/tex]

The value of [tex]sin120=\frac{\sqrt{3} }{2}[/tex]

The value of [tex]sin140=0.6428[/tex]

The value of [tex]sin160=0.3420[/tex]

Substituting the values of sin, we get,

[tex]sin100.sin120.sin140.sin160=0.9848*\frac{\sqrt{3} }{2} *0.6428*0.3420[/tex]

Multiplying the values of sin, we get,

[tex]sin100.sin120.sin140.sin160=0.1875[/tex]

Thus, the value of [tex]sin100.sin120.sin140.sin160[/tex] is [tex]0.1875[/tex]

Answer:

On the blueprint the dimensions are 48 inches by 64 inches.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be [tex]x[/tex] by [tex]y.[/tex]

As, given the scale on blueprint:

[tex]\frac{1}{4}\ inch=1\ foot[/tex]

So, [tex]\frac{1}{4}\ inch[/tex]  is equivalent to 1 foot.

Thus, [tex]x[/tex] is equivalent to 12 feet.

And, [tex]y[/tex] is equivalent to 16 feet.

Now, solving by cross multiplication method:

[tex]\frac{\frac{1}{4}}{1} = \frac{x}{12}[/tex]

[tex]\frac{4}{1} =\frac{x}{12}[/tex]

By cross multiplying we get:

[tex]48=x[/tex]

[tex]x=48\ inches.[/tex]

Now, again:

[tex]\frac{\frac{1}{4}}{1} =\frac{y}{16}[/tex]

[tex]\frac{4}{1} =\frac{y}{16}[/tex]

By cross multiplying we get:

[tex]64=y[/tex]

[tex]y=64\ inches.[/tex]

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.

Answer: You might have messed up the question

Here is the answer based on your question

W (Bottled water) = 7/2$

N (Cheese Nachos) = -1/2$

Step-by-step explanation:

2W + 3N = $5.50

3W + 2N = $9.50

Find the common number and subtract them. In order to find isolate the water bottles or nachos. I will do water bottles

15 (2W + 3N = $5.50)

10 (3W + 2N = $9.50)

30w + 45N = $82.5

Minus

30W + 20N = $90

= 25N = -12.5

N = -1/2$

Substitute for N

3W + 2(-1/2) =9.5

3w -1 = 9.5

3w - 10.5

w = 7/2$

Answer:

[tex]Width = 2\frac{1}{4}cm[/tex]

[tex]Length=5\frac{5}{12} cm[/tex]

Step-by-step explanation:

Data from the question;

Perimeter of a rectangle is [tex]15\frac{1}{3}[/tex] cm

Length is [tex]3\frac{1}{6}[/tex] cm longer than the width

We are supposed to determine the length and the with of the rectangle;

Assuming, the width x cm

Then, the length is [tex]x+3\frac{1}{6}[/tex] cm

We need to know that the perimeter of a rectangle is given by;

Perimeter = 2 ( length + width)

Therefore;

[tex]15\frac{1}{3}= 2 ( x + (x+3\frac{1}{6}))[/tex]

[tex]15\frac{1}{3}=2(2x+3\frac{1}{6})[/tex]

Thus;

[tex]15\frac{1}{3}=4x+6\frac{1}{3}[/tex]

[tex]4x=9\\x=2\frac{1}{4}[/tex]

Therefore;

[tex]Width = 2\frac{1}{4}cm[/tex]

[tex]Length = x + 3\frac{1}{6}[/tex]

           [tex]=2\frac{1}{4}+3\frac{1}{6}[/tex]

            [tex]=5\frac{5}{12} cm[/tex]

Therefore; the length is [tex]5\frac{5}{12}[/tex] cm while the width is [tex]2\frac{1}{4}[/tex] cm

Answer:

x = 4 and x = 7

Step-by-step explanation:

Given that the segment in the triangle is parallel to the third side of the triangle and intersects the 2 sides then it divides these 2 sides in proportion, thus

[tex]\frac{x}{12}[/tex] = [tex]\frac{x+1}{15}[/tex] ( cross- multiply )

15x = 12(x + 1) ← distribute

15x = 12x + 12 ( subtract 12x from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Answer:

  16 ft

Step-by-step explanation:

One of the other three sides is 12 ft. After that fence is subtracted from the total, there are 32 ft of fence left for the other two sides of the rectangle. That allows those sides to be 32 ft/2 = 16 ft long.

The rectangle can be 12 ft by 16 ft. The longer dimension is 16 ft.

The longer dimension of the rectangular garden is 16 feet. This is found by understanding the perimeter of a rectangle and subtracting the known side from the total fencing available before dividing the result by 2.

The subject of this question is Mathematics, specifically related to the area and perimeter of rectangles. To find the length or the longer dimension of the rectangular garden, we need to understand the concept of the perimeter of a rectangle. The perimeter is the sum of all sides of the rectangle. Here, the problem provides us with one side of the rectangle to be 12 feet and the sum of the remaining three sides to be 44 feet.

Considering that the rectangular garden has two equal longer sides and two equal shorter sides, we can say the shorter side is 12 feet. Therefore, the combined length of the other two sides (the longer sides) must be 44-12=32 feet. Because these are equal, each one is 32/2 = 16 feet.

Therefore, the longer dimension of the rectangular garden is 16 feet.

Answer:

The numbers are 32 , 48

Step-by-step explanation:

Average = 40

Sum of two numbers = 40 * 2 = 80

Let one number =x

Other number = 80 - x

Product of two numbers = GCD * LCM

x*(80-x) = 16*96

80x - x² = 1536

1536 + x² - 80x = 0

x² - 80x + 1536 = 0

x² - 48x - 32x + (-32) * (-48) = 0

x (x -48x) -32 (x -48) =0

(x - 48) ( x - 32) = 0

x - 48 = 0    ; x - 32 = 0

x = 48          ; x = 32

Since 2323 = 23*101 has no perfect square factors, this means we cannot simplify [tex]\sqrt{2323[/tex] into the form [tex]a\sqrt{b}[/tex]

It seems like your teacher may have made a typo. I would double check with them.

-----------------------------------------------------------------------

I'll show you how to simplify a different problem. Let's say we want to simplify [tex]\sqrt{232}[/tex]

Find the prime factorization of the radicand:

232 = 2^3*29

we can rewrite the "2^3" as "2^2*2" to pull out the perfect square factor, which helps us simplify as such:

[tex]\sqrt{232} = \sqrt{2^3*29}[/tex]

[tex]\sqrt{232} = \sqrt{2^2*2*29}[/tex]

[tex]\sqrt{232} = \sqrt{2^2*58}[/tex]

[tex]\sqrt{232} = \sqrt{2^2}*\sqrt{58}[/tex]

[tex]\sqrt{232} = 2*\sqrt{58}[/tex]

For the last two steps I used these square root rules

[tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex]

[tex]\sqrt{x^2} = x[/tex] where x is nonnegative

Final answer:

The square root of 2323 in simplest radical form is 29√3, where 29 is the number outside the radicand and √3 is the radicand.

Explanation:

When simplifying the square root of 2323 to its simplest radical form, the goal is to express the square root as a product of a radicand that has no perfect square factors other than 1, and a number outside the radicand, if possible. We start by finding the prime factors of 2323 and look for pairs of prime factors, as pairs will be taken out of the square root as single numbers. Upon factoring 2323, we find that it can be expressed as 2323 = 29 x 29 x 3. Taking the square root of this expression gives us:

√2323 = √(29 x 29 x 3)

Recognizing that 29 is a perfect square, we take the square root of 29 x 29, which gives us 29. The square root of 3 remains inside the radicand since it is not a perfect square:

√2323 = 29√3

Therefore, √2323 in simplest form as a radicand and a number outside the radicand is 29√3.

Addition of 6q + 1 and q + 11 is 7q + 12

Solution:

Given that, we have to add the given two expressions

Given expressions are:

6q + 1 and q + 11

We have to add both the expressions

Addition of 6q + 1 and q + 11 = 6q + 1 + q + 11

Add the coefficients of same variable. Here "q" is present in two terms

Therefore, add 6q and q

Similarly, add the constants 1 and 11

Thus finally addition is done as:

[tex]6q + 1 + q + 11 = 7q +12[/tex]

Thus addition of 6q + 1 and q + 11 is 7q + 12

After 4 weeks, Macy and Robby will have same amount in their accounts.

Step-by-step explanation:

Given,

Amount saved by Macy each week = $12.50

Let,

x be the number of weeks.

M(x) = 12.50x

Amount saved by Robby each week = $7.50

Amount Robby already have = $20

R(x) = 7.50x + 20

For same amount;

M(x) = R(x)

[tex]12.50x=7.50x+20\\12.50x-7.50x=20\\5x=20[/tex]

Dividing both sides by 5

[tex]\frac{5x}{5}=\frac{20}{5}\\x=4[/tex]

After 4 weeks, Macy and Robby will have same amount in their accounts.

After 4weeks, Macy and Robby will have the same amount in their bank accounts.

To determine after how many weeks Macy and Robby will have the same amount in their bank accounts, we can set up an equation based on their weekly savings and initial amounts.

Let M(t) represent Macy's savings after  t weeks, and R(t) represent Robby's savings after t weeks.

Macy's savings can be expressed as:

M(t) = 12.50t

Robby's saving can be expressed as:

R(t) = 20 + 7.50t

We want to find the number of weeks t such that  M(t) = R(t)

Setting up the equation:

12.50t = 20 + 7.50t

To solve for t, first subtract  7.50t from both sides:

12.50t - 7.50t = 20

5t = 20

Next, divide both sides by 5 to solve for t

[tex]\[ t = \frac{20}{5} \][/tex]

t = 4

Therefore, after 4weeks, Macy and Robby will have the same amount in their bank accounts.

The expressions representing the total flyers each girl will label, the number of earrings Rhonda has, and the amount of money Gina has are 50 + f/4, 0.5x + 15, and 2x + 50, respectively.

The correct answer for the following question 1) option (D), question 2) option (B) and for question 3) option (A)

To determine the number of flyers each girl will label including the additional flyers, we assume that Marilyn and her three friends will continue to share the work evenly. They have labeled 200 flyers so far, equally, which means each has labeled 200 / 4 = 50 flyers. If f represents the number of additional flyers they will label, and they continue to share this work equally, each will label f/4 more flyers. Thus, the total number each girl will label is 50 (already labeled) + f/4 (additional), represented by the expression 50 + f/4, which corresponds to option D.

For the number of earrings Rhonda has, if x represents the number of earrings that Sharon has, Marilyn has half of this amount, or 0.5x. Rhonda has 15 more than Marilyn, so the total number of earrings Rhonda has can be represented by the expression 0.5x + 15, which is option B.

In the case of the savings, if x represents the amount of money Sam has, Hector has twice this amount, so Hector has 2x. Ted has saved $100 more than Hector, leading to 2x + $100. Gina saved $50 less than Ted, which is (2x + $100) - $50, simplified to 2x + 50, and that corresponds to option A.

Step-by-step explanation:

The rate of increase in population is r = 12,600 people/year.

We want to find the rate of change in the population of Austin, Texas in the years between 1980 and 1990.

We will assume that this increase in population is modelled with a linear equation, remember that a general linear equation is y = ax + b.

Where the rate of change, or slope, is a.

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope is given by the formula: m=(y₂-y₁)/(x₂-x₁).

For this case we have two points, these are:

(1980, 346,000)

(1990, 472,000)

Then the slope or rate of change is (472,000-346,000)/(1990-1980)

=12,6000/10

=12,600

Therefore, the rate of increase in population is r = 12,600 people/year.
