Work out the difference between 5/9and4/9

Answer:

what should we do to the question

Answer:

(4,4)

Step-by-step explanation:

The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.

x^2 - 6x + 12 = 2x - 4

x^2 - 8x + 16 = 0

(x - 4)^2 = 0

x = 4

Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.

y = 2x - 4 = 2(4) - 4 = 4

Therefore, the solution of this system of equations is (4, 4).

Therefore, the correct answer is (4, 4).

Total number of ways to paint rooms is 19,740.

We can solve this problem using the combinatorics. First, we choose the color for the living rooms, which can be done in 3*2 = 6 ways (yellow, red, or purple). Then, we choose the colors for the remaining 10 rooms.

Case 1 : living room is yellow and red

Then remaining colors are 3 yellow, 4 red, 3 purple

number of ways to paint living room = 2

number of ways to pain bedroom = 10!/(3! 4! 3!)

So number of ways = 2 * 10!/(3! 4! 3!) = 8400

Case 2 : living room is yellow and purple

Then remaining colors are 3 yellow, 5 red, 2 purple

So number of ways = 2 * 10!/(3! 5! 2!) = 5040

Case 3 : living room is red and purple

Then remaining colors are 4 yellow, 4 red, 2 purple

So number of ways = 2 * 10!/(4! 4! 2!) = 6300

Total number of ways = 8400 + 5040 + 6300 = 19,740

An ogive is used to plot cumulative frequency or cumulative relative frequency of each class against the upper limit of the corresponding class when displaying quantitative data. Option B.

An ogive is a graph that represents a cumulative distribution function (CDF) of a frequency distribution. It shows the cumulative relative frequency or cumulative frequency of each class plotted against the upper limit of the corresponding class. In other words, an ogive can be used to represent data through graphs by plotting the upper limit of each class interval on the x-axis and the cumulative frequency or cumulative relative frequency on the y-axis.

An ogive is used to display the distribution of quantitative data, such as weight, height, or time. It is also useful when analyzing data that is not easily represented by a histogram or a frequency polygon, and when we want to determine the percentile or median of a given set of data. Based on the information given above, option B: "Cumulative frequency or cumulative relative frequency of each class against the upper limit of the corresponding class" is the correct answer.

Triangle KVM is similar to triangle BVG because angle M = angle G = 90° and angle V is common to both triangles.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio.

For two triangles to be similar, the corresponding angles must be congruent i.e equal.. Also the ratio of the corresponding sides of similar triangles are equal.

angle M and G are both 90° , this means they are equal.

angle KVM = BVG

therefore angle K = angle B

Answer:

-7/3

Step-by-step explanation:

The first step is to combine like numbers. Although there are several different ways to go about doing this, I started by adding 2y to both sides which left me with -8-6y=6. I then added 8 to both sides and got 6y=14. Now divide 6 on both sides to get "y" by itself which left me with y = -14/6. When you simplify the answer you get -7/3.

We have shown that |g(x) - g(y)| < 12ε whenever |x - y| < δ. Since ε was arbitrary, this shows that g(x) is uniformly continuous on (0, 1).

A stronger version of continuity known as uniform continuity ensures that functions defined on metric spaces, such as the real numbers, only vary by a small amount when their inputs change by a small amount. Contrary to uniform continuity, continuity merely demands that the function act "locally" around each point. To clarify, this means that for any given point x, there exists a tiny neighbourhood around x such that the function behaves properly inside that neighbourhood.

For the function g(x) to be continuous we need to have any ε > 0, and  δ > 0 such that if |x - y| < δ, then |g(x) - g(y)| < ε for all x, y in (0, 1).

Now, g(x) is bounded as the parent function f(x) is bounded.

Suppose, (0, 1) such that  |x - y| < δ.

Thus, without generality we have:

|g(x) - g(y)| = |x(1-x)f(x) - y(1-y)f(y)|

= |x(1-x)(f(x) - f(y)) + y(f(y) - f(x)) + xy(f(x) - f(y))|

≤ x(1-x)|f(x) - f(y)| + y|f(y) - f(x)| + xy|f(x) - f(y)|

< x(1-x)4ε + y4ε + xy4ε (by the choice of δ)

= 4ε(x(1-x) + y + xy)

< 4ε(x + y + xy)

≤ 4ε(1 + 1 + 1) = 12ε

Hence, we have shown that |g(x) - g(y)| < 12ε whenever |x - y| < δ. Since ε was arbitrary, this shows that g(x) is uniformly continuous on (0, 1).

\( = > x = - \frac{49}{15} \)

\( = > x = - 3 \frac{4}{15} (ans)\)

Answer:

x = - \(\frac{49}{15}\)

Step-by-step explanation:

Given

2x - \(\frac{1}{3}\) + 3 = x - \(\frac{3}{5}\)

Multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions

30x - 5 + 45 = 15x - 9 , that is

30x + 40 = 15x - 9 ( subtract 15x from both sides )

15x + 40 = - 9 ( subtract 40 from both sides )

15x = - 49 ( divide both sides by 15 )

The area of the irregular shape is 63 ft². Answer: a = 63 ft².

To find the area of the irregular shape, we can break it down into smaller rectangles and triangles, and then sum up their areas.

First, let's calculate the areas of the rectangles:

Rectangle 1: Length = 6 ft, Width = 4 ft

Area = Length × Width = 6 ft × 4 ft = 24 ft²

Rectangle 2: Length = 1 ft, Width = 12 ft

Area = Length × Width = 1 ft × 12 ft = 12 ft²

Rectangle 3: Length = 4 ft, Width = 4 ft

Area = Length × Width = 4 ft × 4 ft = 16 ft²

Now, let's calculate the areas of the triangles:

Triangle 1: Base = 6 ft, Height = 1 ft

Area = (Base × Height) / 2 = (6 ft × 1 ft) / 2 = 3 ft²

Triangle 2: Base = 4 ft, Height = 4 ft

Area = (Base × Height) / 2 = (4 ft × 4 ft) / 2 = 8 ft²

Finally, sum up the areas of all the rectangles and triangles:

Total Area = Rectangle 1 Area + Rectangle 2 Area + Rectangle 3 Area + Triangle 1 Area + Triangle 2 Area

= 24 ft² + 12 ft² + 16 ft² + 3 ft² + 8 ft²

= 63 ft²

Therefore, the area of the irregular shape is 63 ft².

ANSWER and EXPLANATION

We are given that m<8 = 23 degrees.

First, let us find m<7.

m<7 and m<8 are angles on a straight line. Angles lying on a straight line sum up to 180 degrees.

This means that:

23 + m<7 = 180

m<7 = 180 - 23

m<7 = 157 degrees

Since m<8 and m<5 also lie on a straight line, we have that:

m<5 = 157 degrees

m<8 and m<6 are vertically opposite angles. Vertically opposite angles are equal, therefore:

m<6 = 23 degrees

m<8 and m<4 are corresponding angles, based on their positions. Corresponding angles are equal, therefore:

m<4 = 23 degrees

m<4 and m<2 are vertically opposite angles, therefore:

m<2 = 23 degrees

m<5 and m<1 are corresponding angles, therefore:

m<1 = 157 degrees

m<1 and m<3 are vertically opposite angles, therefore:

m<3 = 157 degrees

To make x the subject means to solve the equation for x (or basically to get x to stand by itself.)

First, we expand the bracket :
h = 4x + 12y + 2

Minus both sides by 12y + 2 :

h - 12y - 2 = 4x

Divide both side by 4 :
(1/4)h - 3y - 1/2 = x

Therefore, x = (1/4)h - 3y - 1/2.

Given:

Total number of curlers = 16

Pink Curlers = 1/4 of 16

Green Curlers = same with pink = 1/4 of 16

Soda Cans = 16 curlers minus pink and green curlers

To determine how many soda can curlers are in Carrie's head, let's determine first how many pink and green there are.

Since there are 1/4 of the curlers are pink, let's determine how many curlers exactly are pink by multiplying 1/4 to 16.

Therefore, there are 4 pink curlers. Similarly, there are also 4 green curlers since it is stated in the problem that they have the same count.

So, 16 curlers minus 4 pink and 4 green curlers, there are 8 soda cans curlers in Carrie's head.

William must make 1806 copies before his total cost is less than the photocopy store.

Let William made x copies from his home photocopier.

Now total cost of x copies = 0.12 x + 162.5

Total cost of x copies from the store = 0.21 x

Now his cost needs to be lower, so we form an inequality to solve this problem.

0.12x + 162.5 < 0.21x

or, 0.12x - 0.21x < -162.5

or, -0.09x < -162.5

or, x > 1805.56

Hence the minimum value of x will be 1806.

Therefore we can say that he needs to make at least 1806 copies.

The two sides of a mathematical equation having an inequality must be equal. In inequality, we compare several values in contrast to equations. The equal sign can be substituted with the less than (or less than as well as equal to), larger above (or greater to), or is not equal to signs.
