Last year there were 620 7th graders. This year the enrollment has increased by 105%. How many 7th graders are there this year?

Answer:

7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Step-by-step explanation:

Multiplying the positive whole number 7 by 3 and adding 1 will get:

(7 × 3) + 1 = 21 + 1 = 22

Multiplying the positive whole number 7 by 2 and adding 8 will get:

(7 × 2) + 8 = 14 + 8 = 22

Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

Step-by-step explanation:

Answer:its B guys not c because kendra should of divde both by 2 and not multiplie it by 2 trust me

Step-by-step explanation:

It is B not A,C,D!

Answer:

a or 1. $40,000 is the down payment

b or 2. 180 months = 15 years

c or 3. $168,400 is the left over payment (including mortgage)

d or 4. $935.56 (the monthly payment)

Step-by-step explanation:

1. To calculate the down payment, we need to calculate 20% of $200,000.

200,000 x 0.20  = $40,000

Therefore, the down payment on the home costs $40,000.

2. Now, let's figure out how many months are in 15 years.

15 x 12 = 180

So, the mortgage will be paid in 180 months.

3. Next, we need to find out how much money needs to be paid in the 15 years.

200,000 - 40,000 = $160,000

This price will also include an annual interest rate of 5.25%. So, we need to find 5.25% of $160,000.

160,000 x 0.0525 = $8,400 <--- interest rate when rounded to the nearest cent.

160,000 + 8,400 = $168,400 <--- total amount over 15 years

4. To find the monthly payment, we must divide the total amount of money ( or  $168,400), by the number of months, (or 180.)

$168,400 ÷ 180 = $935.56 when rounded to the nearest cent.

Hope this helps! :)

Answer:

(1, -2)  Option A in your list of possible answers

See attached image.

Step-by-step explanation:

We need to graph the lines by using a couple of points on the plane for each equation.

For example:

the points (0, -3)  and (3, 0) for the line  y = x - 3

and the points (0, 1) and (-1, 4) for the line  y = - 3 x + 1

Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.

Answer: the larger number is 54

Step-by-step explanation:

x + y = 56

xy = 108

x = 56 - y

substitute the x value in equation

(56 -y) y = 108

56y - y^2 = 108

y^2 - 56y + 108 = 0

=(y - 2)(y - 54)

The two numbers are 2 and 54.

Multiplication is the process of adding a number up to a given number.

Given that, the sum of the two numbers is 56 and their product is 108.

Let the numbers are x and y then,

x + y = 56    (1)

xy = 108

x = 108/y

Substitute x = 108/y into equation (1):

108/y + y = 56

108 + y² = 56y

y² -56y + 108 = 0

y² -54y -2y + 108 =0

y(y - 54) -2(y - 54) = 0

(y - 2)(y - 54) = 0

y =2 or y = 54

Now, for y = 2 the value of x is 54 and for y = 54 the value of x is 2.

Hence, the two numbers are 2 and 54.

Step-by-step explanation:

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of the expression 4 + [tex](m - n)^4[/tex] at m = 7 and n = 5 is 20.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3 + 4x = 5 is an expression.

We have,

An expression:

4 + [tex](m - n)^4[/tex]

We will solve the expression when m = 7 and n = 5.

Now,

4 + [tex](m - n)^4[/tex]

= 4 + [tex](7 - 5)^4[/tex]

= 4 + [tex]2^{4}[/tex]

[tex]2^{4}[/tex] = 2 x 2 x 2 x 2 = 16

= 4 + 16

= 20

Thus,

The value of the expression 4 + [tex](m - n)^4[/tex] at m = 7 and n = 5 is 20.

Answer: g(x) = (1/3)*(-x)^2 + 3.

Step-by-step explanation:

Let's define all the transformations in a general way,

A vertical contraction/dilation of a scale factor a is written as:

g(x) = a*f(x)

where if a > 1, it is a dilation.

if  0 < a < 1, it is a contraction.

A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:

g(x) = f(-x).

A translation of A units up (A positive) is written as:

g(x) = f(x) + A.

Then for this case we have:

A dilation with scale factor 1/3.

g(x) = (1/3)*f(x)

A reflection over the y-axis.

g(x) = (1/3)*f(-x)

A translation of 3 units up.

g(x) = (1/3)*f(-x) + 3

(in that order, remember that the order in which you applly the transformations matters)

Then g(x) = (1/3)*f(-x) + 3

and f(x) = x^2, so we can replace that in the equation for g(x)

g(x) = (1/3)*(-x)^2 + 3.

Transformation involves changing the position of a function.

The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

The parent function is given as:

[tex]\mathbf{f(x) = x^2}[/tex]

The rule of vertical shrink by a factor of 1/3 is:

[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]

So, we have:

[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, we have:

[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]

[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]

The rule of translation 3 units right is:

[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]

So, we have:

[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

Answer:

Mean: 8 free throws

Standard Deviation: 1.3 free throws

Step-by-step explanation:

This is a binomial random variable, so we can use the formula [tex]ux = np[/tex], where n is the number of trials, and p is the probability. Since we know both of these values, just plug it in for the mean. [tex]ux = .8*10 = 8[/tex]

For the standard deviation, we use the formula σ = [tex]\sqrt{np(1-p)}[/tex]. Since we know what np is, we can replace those 2, giving us [tex]\sqrt{8(1-p)}[/tex]. Again, p is our probability, so this gives us our final equation of [tex]\sqrt{8(1-.8)}[/tex], which simplifies to [tex]\sqrt{8(.2)}[/tex]. Using a calculator, we get 1.264, which is 1.3 rounded to the nearest tenth.

Answer: 7 years

Step-by-step explanation:

Let t be the number of periods in which geese doubles .

The exponential growth function:[tex]y=Ab^t[/tex] , where A = initial value , b= growth factor.

As per given , A = 5 , b=2

i.e. Number of geese after t periods = [tex]y=5(2)^t[/tex]

Put y=111, we get

[tex]111=5(2)^t\\\\\Rightarrow\ \dfrac{111}{5}=2^t\\\\\Rightarrow\ 22.2=2^t[/tex]

Taking log on both sides , we get

[tex]\log 22.2 = t\log 2\\\\\Rightarrow\ 1.346353=t(0.30103)\\\\\Rightarrow\ t=\dfrac{1.346353}{0.30102}\\\\\Rightarrow\ t=4.47263636\approx4.47[/tex]

Now , total months = 4.47 x 18 =80.46≈ 80 months

since 1 year =12 months

Number of years it will take [tex]=\dfrac{80}{12}=\dfrac{20}{3}=6.66666666667\approx7[/tex]

Hence, it will take 7 years (approx.)
