Answer:

19.7

Step-by-step explanation:

Answer:

Hi, the answer would be $11.21 after rounding.

Step-by-step explanation:

I see what you mean about the 49, but remember that when writing a price you only have two spots after the decimal. Yes, your decimal placing is correct!

So, after rounding and multiplying correctly you would get about $11.21

Answer:

-2 is the only answer

Step-by-step explanation:

You know the answer can't be a positive number because a positive multiplied by a positive is a positive number. It is not 0 because 0 X anything is 0. -16 x 16 is way to high. But, -2 x 2 = -4

There are no real solutions

Option F is correct.

An imaginary number is a number that, when squared, has a negative result. Essentially, an imaginary number is the square root of a negative number and does not have a tangible value.

Given equation

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

Apply square root on both sides of the equation

[tex]\sqrt{x^{2} } =\sqrt{-4}[/tex]

[tex]x=2i[/tex]

2i is imaginary number.

There are no real solutions

Hence, Option F is correct.

Answer: 2285.71

Step-by-step explanation:

Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.

r = R/100 = 5%/100 = 0.05 per year.

Solving the equation:

P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143

Answer:

Grandma deposited 8,000

Step-by-step explanation:

I = 3200

r = 5 %

t = 8 years

[tex]P =\dfrac{I*100}{r*t}\\\\P = \dfrac{3200*100}{8*5}\\\\P= 8000[/tex]

Answer:

Huh?

Step-by-step explanation:

I do not see anything.

The cost per box of cookies is $3.75

The total amount Hannah raised from the sales of cookies is $52.50

The total amount Mallory raised from the sales of cookies and donations is $88.50

In order to determine the cost per box of cookies, take the following steps:

The first step is to determine the total sum of the boxes sold by Hannah and Mallory

Sum of the boxes sold = 14 + 22 = 36 boxes

36 boxes were sold by Hannah and Mallory

The second step is to determine the total cost of the 36 boxes sold.

Total cost of 36 boxes = total amount raised - donation

$141 - $6 = $135

The third step is to determine the total cost of each box

cost of one box = total cost of 36 boxes / total number of boxes

135 / 36 = $3.75

The total amount Hannah raised = cost per box x number of boxes she sold

14 x $3.75 = $52.50

The total amount Mallory raised = amount raised from the sale of cookies + donation

amount raised from sales = cost per box x number of boxes she sold

22 x $3.75 = $82.50

Total amount = $82.50 + $6 = $88.50

Step-by-step explanation:

Plug in -3 for f(x) into the first equation.

-3 = x^2 - 5x + 3

x^2 - 5x + 6 = 0

Factor!

(x - 3)(x - 2) = 0

Set each binomial equal to 0 to get the x-value of the point.

x = 3

x = 2

Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.

(3)^2 - 5(3) + 3

9 - 15 + 3

-6 + 3

-3

(2)^2 - 5(2) + 3

4 - 10 + 3

-6 + 3

-3

Ordered pairs of the solutions for this system of equations: (2, -3) and (3, -3)

Answer:

D) [0, ~)

Step-by-step explanation:

Domain of a Function:

the domain of a function is the set of values of x, the independent variable, that are responsible for the graph of the function.

For Example:

suppose, we have a function:

f(x) = 3x - 1

and it's domain is {1, 2, 3}

that means, the corresponding value of f(x) to these 3 values of x will be DEFINED, I.e., they exist and can be plotted on a graph.

The given function:

Therefore, for the given function, it's domain will be those values of x(the ones plotted on the horizontal line), that give some value to the function ,i.e., for which we can draw it's graph.

and since the graph starts from x = 0 and continues towards infiinity

(the arrow on the curve shows that the graph continues and hasn't yet come to a stop.)

So, that way we got [0, ~). ^^

Answer:

a₂₁ = 41

Step-by-step explanation:

The nth term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then

a₂₁ = 1 + (20 × 2) = 1 + 40 = 41

The coordinates of the image point will be P''(7, 5).

Given is to translate P(4, 0) right by 3 units and up by 5 units.

Rightward translation : P'(4 + 3, 0 + 0) = P'(7, 0)

Upward translation : P''(7 + 0, 0 + 5) = P''(7, 5)

Therefore, the coordinates of the image point will be P''(7, 5).

Answer:

D) Squares, rectangles, rhombuses and trapezoids are quadrilaterals

Answer:

There is a positive correlation between both variables.

Step-by-step explanation: That is to say, the relation between the cost and the size of the storage containers is growing.

As the size of the container increases the cost also increases.

The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium positive correlation

A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.

The costs and sizes of the containers are moderately correlated.

A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.

We have,

The correlation coefficient for the costs and sizes of the storage container is 0.55.

We know that,

Correlation coefficients whose magnitude is between 0.5 and 0.7 indicate that the variables are moderately correlated.

Correlation coefficients whose magnitude is between 0.3 and 0.5 indicate that the variables are a low correlation.

Since the correlation coefficient for the costs and sizes of the storage container is 0.55, it is between 0.5 and 0.7.
So it is moderately correlated.

Thus the costs and sizes of the containers are moderately correlated.

Answer:

Manuel

Step-by-step explanation:

You should set up a proportion graph first such as r:c where r is the amount of minutes spent on resistance and c is the amount of minutes spent on cardio.

Alex's ratio: 24:30

Carisa's ratio: 15:20

Manuel's ratio: 14:15

Now you have to find the lowest common multiple (lcm) of the cardio minutes. Their lcm is 60. Now the ratios look like this:

Alex's ratio: 48:60

Carisa's ratio: 45:60

Manuel's ratio: 56:60

The ratio with the highest first number is considered larger. In this case its Manuel since he has the number 56.

a. True.

b. False. Only the sum of the exterior angles is 360°.

c. True.

d. True.
