Answer:

10.20

Step-by-step explanation:

Given;

A DVD is marked down 15%; the regular price is $12.

To Find;

What is the sale price?

Note;

Mark Down = Decrease = Subtract

Solve;

$12 x 15% = 1.80

$12 - 1.80 = 10.20

15% of 12 is 1.80 so subtract 1.80 from 12 and you get 10.20

Answer:

Option A:  an exponential graph decreasing from the left and crossing the y axis at 0 comma 5

Step-by-step explanation:

It has to start with a y-intercept of 21 because f(x) or as another way of saying it, y, equals 21 and then the number has to halve itself and thats why its so steep in the beginning.  Hope this helps :)

Answer:

Let's find the unit rate first, I like to order my units:

_________ = ______ = ______________, so 3 patients per hour is the

-unit rate.

Now let's order them to equal x(unknown patients)/9(hours)

___________  =   __________ = 27 patients per 9 hours. So your answer

is 27 patients.

Answer:

27 patients

Step-by-step explanation:

18patients = 6 hours

18/6 = 3

each hour for 6 hours she attends to 3 patient

6 hours + 3 hours make up 9 hours

since for each hour she attended to three patients we would say

1 hr = 3 patients

1 hr = 3 patients

1 hr = 3 patients

Total: 3 hrs = 9 patients

18 patients + 9 patients = 27 patients

so for 9 hrs Katherine will visit 27 patients.

Answer:

I'd rather use an explicit rule for bigger values of n

Step-by-step explanation:

Suppose we have a sequence like:

6,14,22,30,..

And we wanted to calculate the 200th term. The recursive rule is:

[tex]a_n=a_{n-1}+8[/tex]

Since each term is 8 more than the previous term. If we wanted to caclulate the term n=200, we would need to go up to 200 one-by-one until reaching the desired value.

The explicit rule is:

[tex]a_n=6+8(n-1)[/tex]

To find the term for n=200, just substitute into the rule:

[tex]a_{200}=6+8(200-1)=1598[/tex]

Thus, I'd rather use an explicit rule for bigger values of n

(2,3)

Step-by-step explanation:

Answer:

(2, 3)

Step-by-step explanation:

The formula for midpoint is: M = [tex]\frac{(x_{1}+x_{2} )}{2} , \frac{(y_{1} + y_{2}) }{2}[/tex]

Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.

Answer:

Width = 3.75 feet

Length = 9.75 feet

Step-by-step explanation:

Given:

Length of fencing = 27 feet

Find:

Dimensions of the garden

Computation:

Assume

Width = x

So,

Length = x + 6

2(L+B) = Perimeter

2(x + x + 6) = 27

2(2x + 6) = 27

4x + 12 = 27

4x = 15

x = 3.75

Width = 3.75 feet

Length = 3.75 + 6 = 9.75 feet

Answer:

-7n - 3

Step-by-step explanation:

5n-3(4n+1) =

5n -12n -3= 0

-7n - 3

Answer: -7n-3

Step-by-step explanation: first bring the 5n down then multiply -3x4n gives you -12 and multiply 5x1 that gives you 5 so you would write (5n−12n)−3

then remove the parentheses combine like terms like 5 and 12 are alike because of the n's that means subtract because of the - sign 5-12 which gives you -7 and then you bring down -3 because it's outside the parentheses and that's the answer.

Answer:

37.5%

Step-by-step explanation:

the savings on the sweater is 140-87.50, or 52.50

you could create a proportion based on the statement:

52.50 is what percent of 140?

is/of = 'x'/100

52.5/140 = x/100

cross-multiply to get:

140x = 5250

x = 5250/140

x = 37.5

Answer: No. Manolo forgot to include that the opposite of squaring a number is square rooting. If you take the square root of 36, you get 6. When you square a number, you multiply it by itself, which is what Manolo did. He multiplied 6 by itself and got the answer of 36.

Step-by-step explanation: Hope this helps!

The Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

A quadratic equation:

g² = 36

Manolo says that the solution of the equation g squared equals 36 is g = 6 because 6×6 = 36

As we know, the quadratic equation has two roots.

To solve the quadratic equation we can use the identity:

a² - b² = (a + b)(a - b)

g² = 36

g² - 36 = 0

g² - 6² = 0

(g + 6)(g - 6) = 0

g + 6 = 0 ⇒ g = -6

g - 6 = 0 ⇒ g = 6

Thus, the Manolos reasoning is not complete because the quadratic equation has two roots and the roots are 6 and -6.

Answer:

  x² +2x -3 = 0

Step-by-step explanation:

Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...

  0 = (x -(-3))(x -1) = (x +3)(x -1)

In standard form, this is ...

  x(x -1) +3(x -1) = 0

  x² +2x -3 = 0 . . . . . . the terms have no common factors

Answer: 15 gallons

Step-by-step explanation:

Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons

918/27 = 510/x

Cross multiply and you get 918x = 13770

and you get x = 15

Or you could do 918 miles / 27 gallons = 34 miles / gallon

and divide the 510 miles of distance by how many miles per gallon, so

510 / 34

15
