39. Sophia has one of each of these cards. 1 3 5 71 9 How many three digit numbers divisible by three can she make with her cards? (Write only the number on your answer sheet)​

Answer: The solution of the ordered pairs are (0,1) and (1,3).

Step-by-step explanation:

There 9% represent babies born with a birth defect, and 09-99(9%) to represents babies without birth defects.

The percentage is defined as a ratio expressed as a fraction of 100.

According to one study, 45 out of every 500 babies born in the world have a serious birth defect.

Use two-digit numbers 00-99; let 00- represent babies born with some kind of major birth defect.

p = x/n

p = 45/500

p = 0.9 = 9%

So, the simplest way to assign random numbers to conduct a simulation based on this statistic, it can use 00-99(9%) to represent babies born with a birth defect, and 09-99(9%) to represent babies without birth defects.

Hence, the correct answer would be an option (B).

Step-by-step explanation:

To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph

The exact solution to the system of equations shown on the graph is

(-1 1/5, 4 3/5)

The solution of a graph is where the two graphs intersects. This point is known as point of intersection and at this point we have the solution

The point of intersection of the two graphs as shown are read, Knowing that all interval marked represents one unit

x intersection: the point is more than -1 and not up to -1.5, which is a value at exactly half of the two intervals hence the possible option is -1 1/5

y intersection: the point is more than 4 and more than to 4.5, which is a value at exactly half of the two intervals hence the possible option is

Step-by-step explanation:

You want to match the given word problem with a suitable equation for solving it.

The variable x is assigned to the larger of two numbers that differ by 2. That makes the smaller one (x -2). The sum of their squares is ...

  x² + (x -2)² = 394

Simplifying, we get ...

  x² +x² -4x +4 = 394

  2x² -4x -390 = 0 . . . . . . . matches the first equation

The numerator of the fraction is 5 more than its denominator, x, so will be (x +5). Adding 3 to numerator and denominator, we get ...

  [tex]\dfrac{(x+5)+3}{(x)+3}=\dfrac{4}{3}\\\\3(x+8)=4(x+3)\\\\\boxed{3x+24=4x+12}\qquad\textsf{matches the third equation}[/tex]

The sum of x and its inverse is 4/3, so we have ...

  x + 1/x = 4/3

Multiplying by 3x gives ...

  3x² +3 = 4x

  3x² -4x +3 = 0 . . . . . . . . . matches the second equation

The required equation is y = 1.4x - 295 shows the amount that must be repaid, y, when x dollars are borrowed.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The table below shows the amount that must be repaid, y, when x dollars are borrowed.

Amount Borrowed     Amount Repaid

Step-by-step explanation:

x² - 18x + 81 = 4 ( subtract 81 from both sides )

x² - 18x = - 77

to complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 9)x + 81 = - 77 + 81

(x - 9)² = 4 ( take square root of both sides )

x - 9 = ± [tex]\sqrt{4}[/tex] = ± 2 ( add 9 to both sides )

x = 9 ± 2

then

x = 9 - 2 = 7

x = 9 + 2 = 11

Dimensions of the portrait are 12.25 cm to the nearest tenth of a centimeter.

What are Dimensions?

The dimension of a mathematical space is defined as the smallest number of coordinates required to specify each point within it.

To have the area of the mat equal to the area of the portrait, the portrait and the mat must have the same area. Since the mat is 7 cm wide, we can use that to find the dimensions of the portrait.

If the portrait is square, the side length will be the same as the width of the mat, plus the width of the portrait.

So, portrait width = 7 cm + portrait width

Solving for portrait width:

portrait width = 7 cm / 2 = 3.5 cm

So, the dimensions of the portrait are 3.5 cm x 3.5 = 12.25 cm

Therefore, dimensions of the portrait are 12.25 cm to the nearest tenth of a centimeter.

Step-by-step explanation:

Let M be the number of multiple choice problems and S be the number of short answer problems.

We can set up the following system of equations to represent this situation:

M * 3 + S * 4 = 111

M + S = 32

The first equation represents the total number of points on the test, and the second equation represents the total number of problems on the test.

To solve this system of equations, we can use a method such as graphing, substitution, or elimination.

Using the substitution method, we can solve for one variable in terms of the other and substitute it into the other equation. For example, we can solve the first equation for M:

M = (111 - S * 4) / 3

Then, we can substitute this expression for M into the second equation:

(111 - S * 4) / 3 + S = 32

Solving this equation for S gives us the number of short answer problems:

S = 12

To find the number of multiple choice problems, we can substitute this value for S into the expression for M that we derived earlier:

M = (111 - 12 * 4) / 3

Solving this equation gives us the number of multiple choice problems:

M = 8

Therefore, there are 8 multiple choice problems and 12 short answer problems on the test.
