Answer:

346.19 m²

Step-by-step explanation:

The diameter of the circular flower bed is 15 m and the length of the sidewalk round the flower bed is 3 m.

This means that an extra length of 3 m is added on each side.

The joint diameter of the flower bed and sidewalk is:

15 + 3 + 3 = 21 m

The radius is half of the diameter, that is 10.5 m

The area of the sidewalk is therefore:

A = pi * r²

Where r = radius

A = 3.14 * 10.5²

A = 346.19 m²

Step-by-step explanation:

Given that

We are given the following:

1. Boys who do play video games = 1593

2. Boys who do not play video games = 858

3. Total boys = 2451

4. Girls who do play video games = 1361

5. Boys who do not play video games = 1635

6. Total Girls = 2996

7. Total number of candidates = Total boys + Total girls

=(2451 + 2996) = 5447

8. Total number of students, who play video games = 2954

9. Total number of students, who do not play video games = 2493

Percentage of boys who play video games:

[tex]\dfrac{1593}{2451} \times 100 = 64.99\%[/tex]

So, option A is not correct.

Percentage of girls who play video games:

[tex]\dfrac{1361}{2996} \times 100 = 45.43\%[/tex]

so option B is correct. The percentage is near about 45%,

Percentage of Total number of students, who do not play video games:

[tex]\dfrac{2493}{5447} \times 100 = 45.77\%[/tex]

So, option C is not correct.

Step-by-step explanation:

If they pay $2,200 to screen a movie and charge $8 a head then it's just division. 2200/8 is equal to 275.

the tickets should be 275 tickets..

The solution for this problem is:

To get the diagonal length of a square,  multiply the length of one side by the square root of 2:If the length of one side is x.

length of diagonal = x √2

length of a diagonal = 4√2

length of a diagonal = 5.6569 feet

Use the Pythagorean theorem

Diagonal = sqrt(4^2 + 3^2)

Diagonal = sqrt( 16 + 9)

Diagonal = sqrt(25)

Diagonal = 5

Answer:

Fraction of the garden used =  [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

The fifth graders to plant a butterfly garden.

We are given that

Clover grows in ½ of the garden

Daisies grow in ¼ of the garden

Coneflowers grow in ⅛ of the garden

milkweed grows in ⅛ of the garden

The fifth graders notice that the butterflies land on the clover and milkweed.

We are asked to find out the fraction of the garden that the butterflies used.

Fraction of the garden used = clover + milkweed

Fraction of the garden used =  [tex]\frac{1}{2} + \frac{1}{8}[/tex]

The LCM of 2 and 8 is 8

Fraction of the garden used =  [tex]\frac{4 +1}{8}[/tex]

Fraction of the garden used =  [tex]\frac{5}{8}[/tex]

Therefore, the butterflies used [tex]\frac{5}{8}[/tex] fraction of the garden.

The point-slope form of the line is [tex]y-19=2(x-5)[/tex].

Important information:

We need to find the point-slope equation for the line

The point-slope form of a line that passes though the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Substitute [tex]x_1=5,y_1=19,x_2=-5,y_2=-1[/tex].

[tex]y-19=\dfrac{-1-19}{-5-5}(x-5)[/tex]

[tex]y-19=\dfrac{-20}{-10}(x-5)[/tex]

[tex]y-19=2(x-5)[/tex]

Thus, the point-slope form of the line is [tex]y-19=2(x-5)[/tex].

Answer:

80%

Step-by-step explanation:

We need to find the percent of change from 3,545 pt to 709 pt.

Original value is 3,545

Changed value is 709

Percent change is given by :

[tex]\%=\dfrac{\text{difference in values}}{\text{original value}}\times 100\\\\\%=\dfrac{3545-709}{3545}\times 100\\\\\%=80\%[/tex]

So, there is 80% of change from 3,545 pt to 709 pt.

Answer:

The area of triangle is 32 cm².

Step-by-step explanation:

When you fold a square into triangle, the length of sides will still be the same. So using area of triangle formula, you are able to find the area :

[tex]area = \frac{1}{2} \times width \times height[/tex]

Let width = 8cm,

Let height = 8cm,

[tex]area = \frac{1}{2} \times 8 \times 8[/tex]

[tex]area = \frac{1}{2} \times 64[/tex]

[tex]area = 32 \: {cm}^{2} [/tex]

Given:

To find out:

Find the area of half fold paper ( triangle) ?

Formula used:

Area of triangle = ½ × b × h

Solution:

We know that,

Area of triangle = ½ × b × h

☆ Substituting the values in the above formula,we get

Area of triangle = ½ × 8 × 8

= 4 × 8

= 32 cm²

Hence the area of given triangle is 32 cm².

Answer: 3, 11

Step-by-step explanation:

Y= 3+8 = 11

X= 11-14=3

Answer:

S(t) = a.sin (b.t) + d

a = -1.5, b = (2π/365), d = 3.47

S(t) = -1.5 sin (2πt/365) + 3.47

Step-by-step explanation:

Complete Question is presented in the attached image to this solution.

- Dingane has been observing a certain stock for the last few years and he sees that it can be modeled as a function S(t) of time t (in days) using a sinusoidal expression of the form

S(t) = a.sin(b.t) + d.

On day t = 0, the stock is at its average value of $3.47 per share, but 91.25 days later, its value is down to its minimum of $1.97.

Find S(t). t should be in radians.

S(t) =

Solution

S(t) = a.sin(b.t) + d.

At t = 0, S(t) = $3.47

S(0) = a.sin(b×0) + d = a.sin 0 + d = 3.47

Sin 0 = 0,

S(t=0) = d = 3.47.

At t = 91.25 days, S(t) = $1.97

But, it is given that T has to be in radians, for t to be in radians, the constant b has to convert t in days to radians.

Hence, b = (2π/365)

S(91.25) = 1.97 = a.sin(b×91.25) + d

d = 3.47 from the first expression

S(t = 91.25) = a.sin (91.25b) + 3.47 = 1.97

1.97 = a.sin (2π×91.25/365) + 3.47

1.97 = a sin (0.5π) + 3.47

Sin 0.5π = 1

1.97 = a + 3.47

a = -1.5

Hence,

S(t) = a.sin (b.t) + d

a = -1.5, b = (2π/365), d = 3.47

S(t) = -1.5 sin (2πt/365) + 3.47
