30 geckos

fraction: [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Let the numbers of geckos be x, the numbers of anole lizards be y

[tex]x:y=3:5[/tex]

⇒ [tex]5x=3y \left \{ {{a:b=cd}[/tex] → [tex]ad=bc[/tex]

Answer:

6. [tex]y=2(0.3)^x[/tex]

7. 3, greater than 1, growth, (0,3)

Step-by-step explanation:

General form of an exponential equation:  [tex]y=ab^x[/tex]

(where a is the initial value, b is the growth/decay factor, and x is the independent variable)

If b > 1, the function represents exponential growth.

If 0 < b < 1, the function represents exponential decay.

Therefore, [tex]y=2(0.3)^x[/tex] represents an exponential decay (as 0 < b < 1)

For [tex]y=3(4)^x[/tex]

The y-intercept is when x = 0 ⇒ [tex]y=3(4)^0=3[/tex]

The value of a is 3.  The value of b is greater than 1.  So, the function represents exponential growth.  The y-intercept is (0, 3)

The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y represent the average annual salary, x years since 2000, hence, from table:

At (2000, 1116000), that is (0, 1116000):

1116000 = ab⁰  

a = 1116000

At (20, 3193000):

3193000 = 1116000(b)²⁰

b = 1.05

The salary in 2025 ( x = 25) is:

y = 1116000(1.05)²⁵ = 4152719.5

The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000

T(n) = 7+n

Step-by-step explanation:

A.P. Formula: a(n) = a + (n-1)d

Since a = 8 (given),

and we know 2*[T(8)] = T(16)

We may set up an equation to find d/

2(8+(8-1)d) = 8+(16-1)d

d = 1

y = 9 - 3x

Step-by-step explanation:

9x + 3y - 27 = 0 ( add 27 to both sides )

9x + 3y = 27 ( subtract 9x from both sides )

3y = 27 - 9x ( divide through by 3 )

y = 9 - 3x

Answer:

l = 32.5 units, w= 27.5 units, A = 893.75 units²

Step-by-step explanation:

width is w

length is l = 5+w

P = 2( l+w) , substitute l for 5+w

P = 2(5+w+w)

P = 2(5+2w)

P = 10 +4w

P = 120

10 +4w = 120

4w = 120-10

4w = 110

w= 110/4

w= 27.5 units

l = 5+w = 5+ 27.5 = 32.5 units

A = l*w = 27.5 * 32.5 = 893.75 units ²

Step-by-step explanation:

Big triangle

Little triangle

Compare lengths & find scale factor (s.f)

We've got base lengths, that's what we will use to find the scale factor.

27.3 ÷ 15.6 = 1.75 s.f

We're going from big triangle, to small; so, divided by 1.75s.f to find length of u

56 ÷ 1.75 = 32

U= 32m

If the plan is monthly, x is equal to minutes, and y is equal to total cost, then the following is true:

Answer:

C: y = 0.25x + 35

Step-by-step explanation:

      Every minute $0.25 is added, so if x is equal to minutes, then part of our equation will be  0.25x.

      If the plan is monthly, then every month there will be a $35 dollar fee. This can be represented by + $35.

      Lastly, y is the total cost so the equation will be set equal to y.

Answer:

$5.50

Step-by-step explanation:

100% of the total bill was $27.50

10% will be 100% divided by 10

10% = $27.50 ÷ 10

10% = $2.75

20% will be double 10%

20% = £2.75 × 2

20% = $5.50

Considering the definition of right rectangular prism and its volume,  the total weight of the contents is 38.81 pounds.

A right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.

To calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.

That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.

In this case, you know that:

So, the volume of the container is calculated as:

7.5 ft× 11.5 ft× 3 ft= 258.75 ft³

Then, the total weight of the contents is calculated as:

258.75 ft³×  0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds

Finally, the total weight of the contents is 38.81 pounds.

Answer: A. 57 degrees

Step-by-step explanation:

If it's a right triangle, that means one of the angles is 90 degrees.

The sum of the angles in a triangle is 180 degrees.

We are given the other angle's measure as 33 degrees.

Therefore the other angle's measure is 180-90-33 = 57 degrees

Answer:

Step-by-step explanation:

4) A photograph costs $20, so the cost of x photographs is 20x.

Similarly, the cost of y prints is $25.

So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.

5) just plug each pair in.

For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.
