Answer:

5/16=s/32

Step-by-step explanation:

What we know:

- a school team has 80 swimmers

The ratio of 7th grade swimmers to every swimmer in their school (counting all the grades) is 5:16. Write a proportion of this for a value of s.

a ratio can also be expressed in a fraction by simply putting it from x:y to x/y

so, the ratio 5:16 can also be expressed as 5/16.

note: let sgs represent seventh grade swimmers.

also, let x represent the value of the equivalent amount of swimmers (in the denominator that serves as a value for the proportion of 5/16.

we need to find:

5 sgs/16 swimmers = s amount of sgs/x

5/16=s/x

equivalent fractions could literally be anything, just multiply that ratio by a value equal to one; ex 4/4, or 16/16, or 2/2.

the simplest proportion is to multiply 5/16 by 2/2.

5/16*(2/2)=s/x

10/32=s/x

so s=10 and x=32 but we only need to know x cuz your problem doesn't have a box to answer the s=10.

so... 5/16=s/32.

Answer:0=4x^2+12x+9

Step-by-step explanation:

The standard form of the quadratic equation is y = 4x² + 12x + 9. Then the correct option is D. And the value of a, b, and c will be 4, 12, and 9.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

The equation is given below.

y = (2x + 3)²

Simplify the equation, then we have

y = 4x² + 12x + 9

Then the correct option is D.

Compare the equation with standard equation, then we have

a = 4

b = 12

c = 9

Answer:

The equation of the circle is x² + y² + 12x - 14y - 165 = 0 , its center is (-6, 7) and its radius is 5√10 units.

Step-by-step explanation:

a. The center of the circle

Since the equation of the tangent of the circle is 3x - y = 15, we write it in standard form. So y = -3x - 15. Its gradient is -3. The perpendicular line tot he tangent is the radius and it passes through the center of the circle and the point (9, 12). For two perpendicular lines of gradient m₁ and m₂, m₁m₂ = -1. If m₁ = -3, then m₂ the gradient of our radius line is gotten from m₁m₂ = -1

m₂ = -1/m₁ = -1/-3 = 1/3

Since the radius also passes through the point (9, 12), its equation is gotten from

(y - y₁)/(x - x₁) = m₂ where (x₁, y₁) = (9, 12)

Substituting the value of the variables into the equation, we have

So, (y - 12)/(x - 9) = 1/3

cross-multiplying, we have

3(y - 12) = (x - 9)

expanding the brackets, we have

3y - 36 = x - 9

collecting like terms, we have

3y = x - 9 + 36

3y = x + 27

So, the equation of the radius line is

3y - x = 27.

Now, since the center of the circle lies on the line 2y + x = 8, the radius line and this line intersect at the center of the circle. So, we solve both equations simultaneously to find the center of the circle.

So, 3y - x = 27  (1)

     2y + x = 8    (2)

adding (1) and (2), we have

5y = 35

y = 35/5

y = 7

Substituting y = 7 into (2), we have

2y + x = 8

2(7) + x = 8

14 + x = 8

x = 8 - 14

x = -6

So, the center of the circle is at (-6, 7)

b. The radius of the circle

The radius of the circle is the length of the line from the tangent point to the center of the circle. So, r = √[(x₂ - x₁)² + (y₂ - y₁)²] where (x₁, y₁) = (-6, 7) and (x₂, y₂) = (9, 12).

Substituting these into r, we have

r = √[(9 - (-6))² + (12 - 7)²]

= √[(9 + 6)² + (12 - 7)²]

= √[15² + 5²]

= √[225 + 25]

= √250

= √25 × √10

= 5√10 units

c. The equation of the circle

Now, the equation of a circle with center (h,k) and radius, r is

(x - h)² + (y - k)² = r² where (h. k) = (-6,7)

Substituting the variables into the equation, we have

(x - (-6))² + (y - 7)² = (√250)²

(x + 6)² + (y - 7)² = 250

expanding the brackets, we have

x² + 12x + 36 + y² - 14y + 49 = 250

collecting like terms, we have

x² + y² + 12x - 14y + 36 + 49 - 250 = 0  

x² + y² + 12x - 14y - 165 = 0

So, the equation of the circle is x² + y² + 12x - 14y - 165 = 0 , its center is (-6, 7) and its radius is 5√10 units.

Answer:  So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50  

Step-by-step explanation:

Let C = cost to rent each chair

Let T = cost to rent each table

 4C + 8T = 73

2C + 3T = 28

 Multiply the 2nd equation by (-2) and then add the equations together  

  4C + 8T = 73

-4C - 6T = -56

 2T = 17

T = 17/2 = 8.5

 Plug this in to the 1st equation to solve for C

 4C + 8(17/2) = 73

4C + 68 = 73

4C = 5

C = 5/4 = 1.25

The value of x is 14.

The correct option is C.

The ratio is a numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

Given:

The smaller triangle was dilated to form the larger triangle.

A smaller triangle has side lengths of 3 and 5.

A larger triangle has side lengths of 9 and x + 1.

That means,

the ratio,

3/5 = 9/(x + 1)

3x + 3 = 45
