Answer:

32 yards

Step-by-step explanation:

Subtract 15.52 by 20 to find out how much she spent.

She spent $4.48.

Divide 0.14 to find out how many yards of ribbon $4.48 can buy.

She bought 32 yards.

Division is one of the four fundamental arithmetic operations. The number of yards of ribbon is 33.93 yards.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that Isabel prepaid a debit card with $20 on it. Also, after that purchase, there was $15.52 left on the card. Therefore, the cost of the total ribbon can be written as,

Cost of total Ribbon = Total Balance in debit card - Balance after purchase

                                  = $20 - $15.25

                                  = $4.75

It is further mentioned that the price of the ribbon was 14 cents per yard. Therefore, we can write,

Yards of ribbon = Cost of total Ribbon / Cost of a yard of ribbon

                          = $4.75 / $0.14 per yards

                          = 33.93 yards

Hence, the number of yards of ribbon is 33.93 yards.

Please find the image uploaded for diagram and solution.

Information about concavity is contained in the second derivative of a function. Given f(x) = ax² + bx + c, we have

f'(x) = 2ax + b

and

f''(x) = 2a

Concavity changes at a function's inflection points, which can occur wherever the second derivative is zero or undefined. In this case, since a ≠ 0, the function's concavity is uniform over its entire domain.

(i) f is concave up when f'' > 0, which occurs when a > 0.

(ii) f is concave down when f'' < 0, and this is the case if a < 0.

In Mathematica, define f by entering

f[x_] := a*x^2 + b*x + c

Then solve for intervals over which the second derivative is positive or negative, respectively, using

Reduce[f''[x] > 0, x]

Reduce[f''[x] < 0, x]

Answer:

$240.00

Step-by-step explanation:

And this problem, we're trying to figure out the probability that Xerxes arrives first and Regina arrives last. Now, the first thing to note is that there are nine people. So if we list off nine different spaces, there's nine spaces and now the order in which they arrive could be any order. So for the first spot there are nine different ways that someone can show up, Anyone can show up first and then once someone has shown up first, the person who arrives second, there are eight different ways to choose that person. Similarly, the person who arrives third, there are seven people remaining, so there's seven ways to choose that and so on. And so there are actually nine factorial ways that the people can arrive to the party. Now if xerxes needs to be in the first spot and Regina needs to be in the last spot than in these remaining seven spaces, we can put any people, so there can be any ordering between xerxes and Regina. So there is seven factorial ways to order the people between xerxes and Regina. So the probability that we end up with is seven factorial divided by nine factorial. So that is seven factorial. And remember that nine factorial can be written as nine times eight times seven factorial. The seven factorial are going to cancel. We get 1/7 times eight which is equal 1/72 which is equal to approximately zero point 014 and that's it

Answer:

4x-4y=20  divide by 4 to get

x-y=5,  now substitute -5 for y

x-(-5) = 5

x+5 = 5

x = 0

or you could immediately notice that by letting y=-5

that

4x +20 = 20 and

4x = 0

x = 0

x-y=5 is the same as

y= x-5 which graphically has slope = 1 with y intercept y=-5

x-intercept is x=5.  Plot those two intercepts or points  (0,-5) and (5,0)  connect them with a straight line. It has slope = 1 or a 45 degree angle with the horizontal.

Answer:

15

Step-by-step explanation:

To subtract 2 1/2 - 1 3/5, first, you need a common denominator for the fractions, which is 10.

The subtraction becomes

2 5/10 - 1 6/10

Now you need to subtract 1 6/10 from 2 5/10.

Since the fraction part involves the subtraction 5/10 - 6/10, we need to borrow. You must change 2 5/10 to a mixed numeral with a larger numerator than 5, so you can subtract 6/210 from it.

Start with 2 5/10.

Borrow 1 from the 2. The 1 you borrow from 2 will be added to 5/10.

You think of the borrowed 1 as 10/10. Now you add 10/10 to 5/10.

2 5/10 becomes 1 15/10. Now that the fraction has a numerator grater than 6, you can do the subtraction.

2 5/10 - 1 6/10 =

= 1 15/10 - 1 6/10

Step-by-step explanation:

Answer:

A. y = 2^x + 5

Step-by-step explanation:

The equation is not linear, so a constant slope does not exist.

Not Linear                     PARALLEL

...................................................................................................................................................

The equation is not linear, so a constant slope does not exist.

Not Linear                         PERPENDICULAR

...............................................................................................................................................

First, remember that if two lines are parallel, they have the same slope. The problem already gave us a point on the line and we now have the power to find the slope. Since we have the slope and a point on the line, we are going to find the equation of the line through the point-slope formula, which is:

 is a point on the line

is the slope of the line

The equation given to us has a slope of 2, as we can see because the line is in slope-intercept form. Also, we are given the point (3, 11), which we are told is on the line. Since we are already given all of the information for the point-slope formula, we can simply substitute it in and solve for the equation.

Set up

Use the Distributive Property on both sides

Add 11 to both sides and simplify

The equation of our line is y = 2x + 5.

...............................................................................................................................................

Slope-intercept form:

y = mx + b   "m" is the slope, "b" is the y-intercept (the y value when x = 0)

For lines to be parallel, they have to have the SAME slope.

The given line's slope is 2, so the parallel line's slope is also 2.

y = 2x + b

To find "b", plug in the point (3,11) into the equation.

y = 2x + b

11 = 2(3) + b      Multiply 2 and 3

11 = 6 + b      Subtract 6 on both sides

5 = b

y = 2x + 5

r = 0.097

converting r decimal to a percentage

R = 0.097 × 100 = 9.7%/year

Answer:

x=9/2

Step-by-step explanation:

Multiply the numbers

8 ( − 1 ⋅ 3/ 4 )= − 3 + 3 3

8 ( − 3 4) = − 3 + 3 3

Distribute

8 ( − 3 4 ) = − 3 + 3 3

8x-6=30

Add six to both sides

8x-6+6=30+6

Simplify

8x=36

Divide both sides of the equation by the same term

8x=36

8x/8 = 36/8

Then you cancel the terms that are in both the numerator and the denominator and divide the numbers

x=9/2

Answer:

x=4.5
