please help me. i’m very stressed.

Answer:

30

Step-by-step explanation:

Given:

Brian Height = 6 feet

Brian Shadow Height = 4 foot

Flag Shadow Height = 20 foot

Flag Height = Unknown ??

So we can use cross multiplication

6/4 = x/20

6×20/4 = x

6×20 =120

120÷4 = 30

So x= 30, which is the Flag Height

I wish that I helped you with this.

As per linear equation, the  height of the flag pole is 30 feet.

A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.

Given, Brian is 6 feet tall and cast a 4 feet shadow.

Therefore, the ratio of Brain and it's shadow is

= 6/4

= 1.5

A flag pole cast a 20 foot shadow.

Therefore, the height of the flag pole is

= 20 × 1.5 feet

= 30 feet.

The equation represents the class's model of the population over time will be P = 50(2)^(n/12). Then the correct option is D.

Consider the function:

y = a (r)ⁿ

Where n is the number of times this growth occurs, a = initial amount, and r = increasing amount of growth.

A biology class at Central High School predicted that a local population of animals will double in size every 12 years.

The population at the beginning of 2014 was estimated to be 50 animals.

If P represents the population n years after 2014.

Answer: D is correct

Step-by-step explanation:

Jordan's error is He should have multiplied the choices, instead of adding them. Thus, the correct option is D.

Whenever you have multiple choices, you have to multiply the number of choices you have in different groups to get the final number of choices.

For example, you have to make a sandwich and you can either use white bread or brown bread. Also, you can either use jam or peanut butter or veggies. Therefore, here the number of choices is 6.

Similarly, Jordan has two choices for type, two choices for transmission, 5 choices for color, and 2 choices for the top. Therefore, the number of choices Jordan has is,

Number of choices in total = 2 × 2 × 5 × 2

Hence, Jordan's error is He should have multiplied the choices, instead of adding them. Thus, the correct option is D.

The amount of money that he should have at the closing of December should be $227.69.

The correct answer choice is option C

Given that,

And, it plans to save 10% more as compared to the last month.

The amount of money that he should have at the closing of December can be solved using the concept of geometric sequence.

First term, a = $24

Common ratio, r = 1.10

Number of terms, n = 7

So,

Sn = a1×(r^n -1)/(r -1)

S7 = 24×(1.10^7 -1)/(1.10 -1)

= (24×0.948717) / 0.10

= $227.69

The total amount Cory will have saved by the end of December is approximately $227.69

Answer:

  (c)  $227.69

Step-by-step explanation:

The amounts Cory will be adding to his account comprise a geometric series with first term $24 and each successive term 10% more, or 1.10 times the previous term. The total amount Cory will have saved by the end of December is the sum of 7 terms of the series.

__

The sum of ...

  24 +1.10×24 +1.10²×24 +... +1.10⁶×24

is given by the formula ...

  Sn = a1×(r^n -1)/(r -1)

where a1 is the first term (24), and r is the common ratio (1.10).

For the series representing Cory's deposits, we have ...

  S7 = 24×(1.10^7 -1)/(1.10 -1) = 24×0.948717/0.10 ≈ 227.69

At the end of December, Cory will have about $227.69.

The set of input of the function are {5, 6, 7, 8, 9,10, 11, 12,13, 14, 15, 16 }

The set of output of the function is a multiple of 40 from 200 to 640

The input of the function can be found as follows:

The camp can only run if we have at least 5 students.

The limits of student is 16.
