Find the product of the
L.C.M and H.C.F of 8 and 12.​

Answer:

700

Step-by-step explanation:

when rounding a number use the place to the right of it so 739 and if its 1-4 then keep the number the same, if 5-9 round up, since its 3 keep it the same and when rounding always get rid of the numbers after number rounded

Answer:

(u o w) (7) =  22

(w o u) 7) = 8

Step-by-step explanation:

We are given:

[tex]u(x)= x^2+6\\w(x)= \sqrt{x+9}[/tex]

We need to find:

a) (u o w) (7)

First we will find (u o w) (x) and then we will find (u o w) (7)

We know that (u o w) (x) = u(w(x))

Put value of w(x) into u(x)

we have:

[tex]u(x)=x^2+6\\Put\: x =\sqrt{x+9}\\u(w(x))=(\sqrt{x+9})^2+6\\u(w(x))=x+9+6\\ u(w(x))=x+15[/tex]

Now finding (u o w) (7)

We know that: (u o w) (7) = u(w(7))

[tex]u(w(x))=x+15\\Put\:x=7\\u(w(7))=7+15\\u(w(7))=22[/tex]

So, (u o w) (7) = 22

b) (w o u) (7)

First we will find (w o u) (x) and then we will find (w o u) (7)

We know that (w o u) (x) = w(u(x))

Put value of u(x) into w(x)

we have:

[tex]w(x)= \sqrt{x+9}\\Put\:x=x^2+6\\w(u(x))= \sqrt{(x^2+6)+9}\\w(u(x))= \sqrt{x^2+6+9}\\w(u(x))= \sqrt{x^2+15}[/tex]

Now finding (w o u) (7)

We know that (w o u) (7) = w(u(7))

[tex]w(u(x))= \sqrt{x^2+15}\\Put\:x=7\\w(u(7))= \sqrt{(7)^2+15}\\w(u(7))= \sqrt{49+15}\\w(u(7))= \sqrt{64}\\w(u(7))= 8[/tex]

So, (w o u) (7) = 8

Answer:

The inverse of a given function

d) [tex]g(x) = \frac{1}{4} x - 3[/tex]

Step-by-step explanation:

Explanation:-

Given that f(x) = 4x + 12

  let y = 4 x + 12

     4 x = y - 12

        [tex]x = \frac{y-12}{4}[/tex]

        [tex]x = \frac{1}{4} y - 3[/tex]      

we know that   y = f(x)

                   ⇒  x = f⁻¹(y)

      [tex](f^{-1} y) = \frac{1}{4} y - 3[/tex]

Put  replace 'y' in 'x'

    [tex](f^{-1} x) = \frac{1}{4} x - 3[/tex]

Final answer:-

The inverse of a given function

[tex]g(x) = \frac{1}{4} x - 3[/tex]

Answer:

(6, -1)

Step-by-step explanation:

The coordinates of the midpoint of a line is [(x₁ + x₂)/2, (y₁ + y₂)/2]. For the given line, JK where J = (-9, 5) = (x₁, y₁) and K = (21,-7) = (x₂, y₂).

So [(x₁ + x₂)/2, (y₁ + y₂)/2]

= [(-9 + 21)/2, (5 + (-7))/2]

= [12/2, (5 - 7)/2]

= [12/2, -2/2]

= (6, -1)

Answer:

The slope is 55.

Step-by-step explanation:

Slope determines the direction and the rate of increase or decrease between the two points on a surface or line.

In the question, it is given initially she is 20 miles north of her house

⇒ When x = 0 the y-coordinate is 20

So, the y-intercept is 20

Now, it is given that the rate of change is 55 miles per hour

Hence, the slope is same as 55 because it is the actual rate of change between the positions of Jennifer with time.

Step-by-step explanation:

Prove ∠RQS = ∠RTS

Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of another triangle.

Statement                            Reason

QS ≅ TS                               Given

RS ≅ RS                               Reflexive property of congruence.      

R is the midpoint of QT       Given

QR = RT                                R is the midpoint of QT. Therefore by

                                             definition, QR = RT.

ΔRQS = ΔRTS                       Side-side-side triangle congruence theorem. If

                                             three sides of one triangle is equal to three

                                             sides of another triangle, then both triangles

                                             are congruent to each other.

∠RQS = ∠RTS                        Corresponding angles of congruent triangles

                                              are equal.

Answer:

14

Step-by-step explanation:

Knowing the first triangle is isosceles, and given the degree is 69.

We can find the top left angle as 180-69-69=42

42 combine with another angle to make a right angle

90-42=48.

The second triangle is also isosceles, so to find 2

we can use 180-42=138 (supplementary angles rule)

and given 10x-8=138

10x=140

x=14

Answer:

Addition

Subtraction so do 3+27 first and you get

30 - 25 = 5

x^4 / x^3 plug it in

(6)^4 / (6)^3

LAW=WKL

By rule: ASA|SAA

Step-by-step explanation

don't know how to explain it

The triangle LAW ≅ WKL by ASA congruence property.

If corresponding two angles and one corresponding side of two triangles are of same measurement, then the considered pair of triangles are congruent.

We have to complete each congruence statement and name the rule used if cannot show the triangles are congruent from the given information leave the triangles name blank .

The triangle LAW ≅ WKL by ASA congruence

WL = WL (COMMON SIDE)

∠ALW = ∠KWL

∠AWL = ∠KLW

Also, These statements can be noted from the image.

Therefore, The triangle LAW ≅ WKL by ASA congruence property.

Answer:

They will meet in 7 hours.

Step-by-step explanation:

They are traveling toward each other, which means that their relative speed is the sum of their speeds.

Bill travels 20 mph and Michael travels 14 mph

This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.

Michael and Bill are 238 miles apart, how long until they meet?

Each hour, they will be 34 miles closer. How many hours for 238 miles?

1h - 34 miles

x h - 238 miles

By rule of three

[tex]34x = 238[/tex]

[tex]x = \frac{238}{34} = 7[/tex]

They will meet in 7 hours.

Answer:

the answer is A. 36

Step-by-step explanation:

because the rectangles are proportionate, I set up ratios.

There are 253 girls in a school.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A school has 575 pupils.

And, There are 56% of the pupils are boys.

Here, 56% of the pupils are boys.

Hence, Percent of the girls = 100% - 56%

                                          = 44%

Since, A school has 575 pupils.

Hence, Number of girls = 44% of 575

                                     = 44/100 × 575

                                     = 253

Answer:

300 ft long

Step-by-step explanation:

divide 1200 by 4 sense the beginners trail is one-fourth the length of the expert trail

The length of beginner trail is 300 meter long.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The tape diagram models the lengths of two snowboarding trails.

And, The expert trail is 1200 meters long.

Now, The length of beginner trail is,

⇒ 1200 / 4 meter

⇒ 300 meter

Thus, We get;

Answer:

The required expression is:

Please check the attached graph too.

Step-by-step explanation:

The slope-intercept form of the linear or line function

[tex]y = mx+b[/tex]

where

In our case,

The cost of hiring a taxi consists of a fixed cost of $3. It means the fixed cost of $3 is the initial condition.

Thus, the y-intercept b = 3

It is stated that the cost of per kilometer distance = $0.5

Thus, the rate of change or slope m = 0.5

As y represents the cost and x represents the number of kilometers.

so substituting m = 0.5 and b = 3 in the slope-intercept form of the linear or line function

y = mx+b

y = 0.5x + 3

Thus, the required expression is:
