An example of an irrational number is

B. V25
C V36
O D. V47

Answer:

Step-by-step explanation:

The question is misleading. It was not specified that his salary is Rs 9,600 per month. That is 115,200 yearly. Of that, 115,200- 85,000 = 30,200 is taxable.

tax = Rs 377.50/month = Rs 4,530/year

4,530/30,200 = 0.15 = 15%

Answer:

8a. x = 16√3

8b. y = 8√3

Step-by-step explanation:

8a. Determination of the value of x

Adjacent = 24

Hypothenus = x

Angle θ = 30°

The value of x can be obtained by using cosine ratio as illustrated below:

Cos θ = Adjacent /Hypothenus

Cos 30 = 24 / x

√3/2 = 24/x

Cross multiply

x × √3 = 2× 24

x × √3 = 48

Divide both side by √3

x = 48/√3

Rationalise

x = 48/√3 × √3/√3

x = 48√3 / √3 × √3

x = 48√3 / 3

x = 16√3

8b. Determination of the value of y

Opposite = y

Adjacent = 24

Angle θ = 30°

The value of y can be obtained by using Tan ratio as illustrated below:

Tan θ = Opposite / Adjacent

Tan 30 = y / 24

1 / √3 = y /24

Cross multiply

y × √3 = 1 × 24

y × √3 = 24

Divide both side by √3

y = 24 /√3

Rationalise

y = 24 /√3 × √3/√3

y = 24 ×√3 / √3 × √3

y = 24√3 / 3

y = 8√3

Answer:

Step-by-step explanation:

We can solve this using a ratio. If there a 2 bottles of cherry in the ratio and there are 34 actual bottles of cherry, then the ratio is

[tex]\frac{ratio}{actual}:\frac{2}{34}[/tex]

In the ratio, we are told that the mix of bottles is 7 parts mango and we want to know how many actual bottles there are of mango. So filling in:

[tex]\frac{ratio}{actual} =\frac{2}{34} =\frac{7}{m}[/tex] and cross multiply to get

2m = 238 and

m = 119. There are 119 bottles of mango juice. And just for the record, there are 17 bottles of fruit juice.

Answer:

m = 119. There are 119 bottles of mango juice. there are 17 bottles of fruit juice.

If a+b=8, b+c=10 and c+a=12, what is the value of a+b+c?

The puzzle is solved by defining each variable in terms of another variable & a number & then making substitutions. Begin by taking each sum to define one of the variables in terms of the other. (Different combinations are available, but I’ll follow the a,b,c order.)

a+b=8 becomes a=8-b

b+c=10 becomes b=10-c

c+a=12 becomes c=12-a

Now subtract two of the equations that contain the same variable. I’ll pick two that contain an a: c+a =12 & a+b=8. Subtracting the latter from the former eliminates the “a”s, leaving c-b=4. Adding b to both sides to isolate c gives c=b+4. From above we can take b=10-c to substitute for b in c=b+4, giving us c=(10-c) + 4). Simplify the right side to c=14-c, add c to both sides, giving 2c=14, & then divide both sides by 2 to obtain c=7.

Replace the c in b=10-c with 7 to

If A = B and B = C, does A = C?

In mathematics = is assumed to be a transitive relationship. Transitivity means precisely what you stated: A = B and B = C implies A = C.

While it’s possible to use = to represent a non-transitive relationship this would be considered an abuse of notation. A ~ B or R(A, B) would be a better way to express the relation in this case.

Similar assumptions are made about operators like + and *. + is generally assumed to be commutative, whereas * can be used for noncommutative operations like matrix multiplication. E.g. A * B != B * A.

Equality in programming is another story entirely.

In many languages = is the assignment operator and == is the equality operator. Assignment is not transitive - it’s not even a relation.There are cases where the equality operator doesn’t define a transitive relation.

Answer:

x=5 is the correct answer

Step-by-step explanation:

First we start off to see if x=3 could work (put the x value in)

11-3<7

(11-3=8)

8<7   This is false

Now lets try the other one-

11-5<7

(11-5=6)

6<7

The value x=5 is the correct answer

Correct choice is C

Answer:

B and C

Step-by-step explanation:

Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.

A minimum point occurs where all the nearby values are higher than that of the point in question.

A maximum point occurs where all the nearby points are lower than the point in question.

By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)

By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.

Answer:

Step-by-step explanation:

Hey there!

Let’s leave number unknown.. so we label it as a “e” for equivalent

NEW EQUATION: 5/10 = e/10

FIRST: you have to CROSS MULTIPLY your given values

5 • 10 = e • 2

5 • 10 = 50

e • 2 = 2e

NEW EQUATION: 2e = 50

SECOND: DIVIDE BOTH of the SIDES by 2

2e/2 = 50/2

Cancel out: 2/2 because that gives you 1

Keep: 50/2 because it helps us solve for e

e = 50/2

= 50/2

= 25

Answer: e = 25 ✅

Overall answer for your given equation: 25/10 ☑️

Good luck on your assignment and enjoy your day!

Answer:

[tex]f(3) =-8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x + 5; x<1[/tex]

[tex]f(x) =-3x + 1; x >1[/tex]

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

[tex]f(x) =-3x + 1[/tex]

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

[tex]f(3) =-3*3 + 1[/tex]

[tex]f(3) =-9 + 1[/tex]

[tex]f(3) =-8[/tex]

The slope is -2.

The slope is the rise over the run. Because the line goes down from left to right, it makes the value negative. For every one the it moves to the right, the line goes down two units.

Answer:

[tex]Speed = 2519.58 mph[/tex]

Step-by-step explanation:

Given

[tex]Distance = 6417.5km[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Required

Calculate the speed in miles per hour

Convert distance to miles

[tex]Distance = 6417.5km[/tex]

[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]

[tex]Distance = 3988.50217526\ miles[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Divide minutes by 60

[tex]Time = 1\ hr + 35/60[/tex]

[tex]Time = 1\ hr + 0.583\ hr[/tex]

[tex]Time = 1.583hr[/tex]

The speed is:

[tex]Speed = Distance/Time[/tex]

[tex]Speed = 3988.50217526/1.583 mph[/tex]

[tex]Speed = 2519.58 mph[/tex]

My calculator works with mixed numbers very nicely, as many graphing calculators do.

Step-by-step explanation:

convert the fractions to whole numbers. the first one is:

4 × 7, then add 3, or 31/4.

the second one is 6 × 1, then add 5, or 11/6.

then you have 31/4 + 11/6. then you make a common denominator, which would be 12 (6 and 4 both go into 12).

3 × 31 = 93, so then the first fractions becomes:

93/12

second fraction becomes 11 × 2 = 22, then:

22/12.

so now you have 93/12 + 22/12 = 115/12, or 9 7/12
