Using proportions, it is found that the correct statement is:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

A proportion is a fraction of a total amount.

In this problem, the table is from a sample of 80 visitors.

Since the proportions stay the same, just the number of visitors change, the correct statement is given by:

D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports.

As from the 80 students, 28 prefer camping and 14 prefer water sports, hence from 200, these numbers will be of 70 and 35 respectively.

Answer: D. The number of visitors who prefer camping will be 2 times the number of visitors who prefer water sports

Step-by-step explanation: If you add up all the number of visitors, you'll get 80. Since we want to find the numbers for the next 200 visitors, we'll divide 200 by 80, which will get us 2.5. Then you'll multiply all the numbers by 2.5 to get:

Camping = 70

Hiking Trails = 55

Water Sports = 35

Biking Trails = 40

After that, you'll just compare the numbers to get your answer.

A triangle has 3 sides.

Add up all the sides to get the perimeter.

So.... divide the perimeter (33) by the number of sides (3) and you get the length of each side. (11)

[tex]33/3 = 11[/tex]

We can check this by using the perimeter of a triangle formula. [tex]P = a + b +b[/tex]

[tex]P = 11+11+11[/tex]

Calculate the volumes of the cylinder and the prism. Subtract.

see image.

Volume is the amount of three-dimensional space enclosed by a closed surface. The volume of the solid is 342.655 cm³.

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity called volume.

The volume of the solid is the difference between the volume of the cylinder and the volume of the square prism.

[tex]\text{Volume of the solid} =\text{Volume of the cylinder}-\text{Volume of the square prism}[/tex]

[tex]\text{Volume of the solid} =(\pi r^2 h)-(a^2 h)[/tex]

We know that the radius of the cylinder is 4 cm while the length of the side of the square prism is 4 and the height of both is 10cm. therefore, substituting the values,

[tex]\text{Volume of the solid} =(\pi\times 4^2 \times 10)-(4^2 \times 10)[/tex]

                               [tex]=4^2\times10 (\pi -1)\\\\= 342.655\RM\ cm^3[/tex]

Hence, the volume of the solid is 342.655 cm³.

Answer:

if c= 1+px^2+3p and b= 2p+6p^2 find an expression that equals 2c-b in standard form

2p² + 14p + 2

Step-by-step explanation:

Given that;

C= 1+p²+3p

B=2p+6p

The expression that equals to : 2C - -B will be;

2{1+p²+3p} - {-2p-6p}

2+2p²+6p + 2p + 6p

2p² + 6p +2p +6p +2

2p² + 14p + 2

.....

If x ≡ 7 (mod 20), then

x ≡ 7 ≡ 27 ≡ 47 ≡ 67 ≡ 87 ≡ … (mod 20)

or equivalently, x = 7 + 20k for some integer k.

Taken mod 4, we have

x ≡ 7 + 20k ≡ 3 (mod 4)

and mod 5,

x ≡ 7 + 20k ≡ 2 (mod 5)

so that a = 3 and b = 2.

Answer:

x = - 2

Step-by-step explanation:

Reflection across the y-axis:

( x , 6 ) ------> ( - x , 6 )

Translation 2 units right and 4 units down:

( - x , 6 ) -------> ( - x + 2 , 6 - 4 ) = ( - x + 2 , 2 )

Dilation by a factor of 2:

( - x + 2 , 2 ) ------> ( ( - x + 2 ) × 2 , 2 × 2 ) = ( 8 , 4 ) ⇒

( - x + 2 ) × 2 = 8

- 2x + 4 = 8

- 2x = 4

x = - 2
