Answer:

Let's say Hamid's normal weight is x.

88kg = 110%x

88kg=11/10x

Divide by 11 on each side

8kg=1/10x

Multiply by 10 on each side

80kg=x

Hamid's normal weight is 80kg

The two bikers are 11.18 miles apart from each other according o the coordinate plane.

A surface with two dimensions made of two number lines is referred to as a coordinate plane. When the origin, the place where the X- and Y-axes intersect, is reached, it is produced. A coordinate grid's numbers are used to find points. For graphing points, lines, and many other things, a coordinate plane is helpful. It functions as a map and gives precise directions on how to get from one place to another.

Distance between two coordinates is given by

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here, (x₁, y₁) is (5, 4) and (x₂, y₂) is (3,-7)

Putting the values in formula

d = [tex]\sqrt{(3-5)^2+(-7-4)^2}[/tex]

d = [tex]5\sqrt{5}[/tex]

d = 11.18 miles

Thus, The two bikers are 11.18 miles apart from each other according o the coordinate plane.

The equation y=3x+5 depicts a straight line with a slope of -3 and a y-intercept of 5, and it is written in slope intercept form. Replace x with any number and solve for y to find ordered pairings that can be graphed.

Write the equation in the form y = mx + b to determine the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept (0, b). Plot the y-intercept next. 3) Depending on whether the slope is positive or negative, go up, down, or left or right from the y-intercept.

You must choose x-values and insert them into the equation in order to graph a function. You will obtain a y-value if you enter those values into the equation. Your coordinates for a single point are made up of your x-values and your y-values.

Answer:

Nick is 6 years old.

Erica is 18 years old.

Step-by-step explanation:

Hello!

We know that Erica is 12 years older than Nick, which also means she is 3 times older than Nick. We can represent this situation as two equations.

Let E be Erica's age, and x be Nick's age.

E = x + 12, and E = x* 3

Since E is equal to E, we can say that x + 12 = 3x.

The value of x is 6. Nick is 6 years old, and Erica is 18 years old.

Answer:

length= 8x

width= x

perimeter of a rectangle= 2L+2W

=2(8x) + 2(x)

Step-by-step explanation:

This for num 2

[tex] \sqrt{8} = \sqrt{2 \times 4} = 2 \sqrt{4} = 2[/tex]

6÷2=3

1.

To solve [tex]\sqrt[n]{16}=2[/tex], you need to turn the question around and ask what value of n makes [tex]2^n=16[/tex].

n = 4

2.

To simplify this, your teacher could mean two things, either "just simplify the radical" or "rationalize the denominator."

For the first option, [tex]\sqrt{8}=\sqrt{4\cdot2}=\sqrt{4}\cdot\sqrt{2}=2\cdot\sqrt{2}[/tex], so your overall expression becomes:

    [tex]\dfrac{6}{2\cdot\sqrt{2}} = \dfrac{3}{\sqrt{2}}[/tex]

Now if your teacher also wants the denominator rationalized, then you keep going and multiply that by [tex]\dfrac{\sqrt{2}}{\sqrt{2}}[/tex]:

    [tex]\dfrac{3}{\sqrt{2}}\cdot \dfrac{\sqrt{2}}{\sqrt{2}}=\dfrac{3\sqrt{2}}{2}[/tex]

Answer:wach the vido

Step-by-step explanation:

The test had 30 number of problem worth 2 points and 8 number of problem worth 5 points

An equation consists of numbers and variables linked together by mathematical operations to form an expression.

Let x represent the number of 2 points and y represent the number of 5 points.

The number of 5 point problems is 22 less than the number of 2 point, hence:

y = x - 22

x - y = 22    (1)

Also, the test is worth 100 points, hence:

2x + 5y = 100    (2)

From both equations:

x = 30, y = 8

30 number of problem worth 2 points and 8 number of problem worth 5 points

The measure of ∠V of the parallelogram is = 150.5°

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the measure of the angle ∠Y = 10x + 27

Let the measure of the angle ∠W = 2x + 29

Now , for a parallelogram the opposite sides are congruent and opposite angles are congruent

Substituting the values in the equation , we get

10x + 27 = 2x + 29

Subtracting 2x on both sides of the equation , we get

8x + 27 = 29

Subtracting 27 on both sides of the equation , we get

8x = 2

Divide by 8 on both sides of the equation , we get

x = 1/4

Let the measure of the angle ∠Y = 10 ( 1/4 ) + 27

Let the measure of the angle ∠Y = 2.5 + 27

Let the measure of the angle ∠Y = 29.5°

Now , same-side interior angles (consecutive angles) are supplementary

Substituting the values in the equation , we get

angle ∠Y + angle ∠V = 180°

29.5° + m∠V = 180°

Subtracting 29.5 on both sides of the equation , we get

m∠V = 150.5°

Hence , the measure of m∠V = 150.5°

The conclusion we can reach is D. If Henry goes to the library, he looks for books on tape.

An inductive proof requires two cases. The first, or base case, establishes the proposition that n = 0 without requiring any prior knowledge of other situations. The second example, the induction step, demonstrates that if the assertion is true for any particular case where n = k, then it must also be true for the subsequent case when n = k + 1. These two actions prove that the statement is true for all n = 1 natural numbers. The base case establishes the truth of the statement for all natural numbers n N, but it does not always start with n = 0. Instead, it frequently starts with n = 1, and it may also start with any fixed natural number n = N.

Given, If Henry goes to the library, he reads a book.

If Henry reads a book, he becomes smarter.

Step-by-step explanation:

The zeroes of the polynomial f(x) are 7, 6 and -1. The solution is obtained by the method of polynomial long division.

What is polynomial long division?

A long division polynomial is a formula for dividing one polynomial by another of the same degree or lower. The divisor, quotient, dividend, and remainder are all components of the long division of polynomials, just like they are for long division of numbers.

We are given f(7) = 0.

This means that (x-7) is one factor of f(x).

Using Polynomial Long Division,

Dividing :  x^3 -12x^2 + 29x + 42 ("Dividend")

By         :    x-7    ("Divisor")

Dividend     x^3  -  12x^2  +  29x  +  42

- divisor  * x2   x^3  -  7x^2        

Remainder      -  5x^2  +  29x  +  42

- divisor  * 5x     -  5x^2  +  35x    

Remainder             -       6x           +  42

- divisor  * (-6)            -       6x           +  42

Remainder                                  0

Quotient :  x^2-5x-6  

Remainder:  0

Now, factoring x^2-5x-6 , we get

⇒x^2-6x+x-6

⇒x(x-6)+1(x-6)

⇒(x+1)(x-6)

Thus, the factors are (x+1), (x-6) and (x-7).

Hence, the zeroes of the polynomial f(x) are 7, 6 and -1.

We will solve our question with the help of the Multiplication rule.

As per the question, the baseball team has won 25 games and lost 12 games. This will give us a total of 25+12= 37 games.

It is given that if the baseball team rate continues through a 148-game season which is 37*4 = 148 games.

So, we should multiply our initial won matches by 4 to get the final won matches as per the given condition, we will get:

25*4 = 100 matches.

We can also find the answer by:

You would multiply 25 by 148 divided by 37 to determine the number of games won if you were comparing the 25 of the 37 games won to the total of 148 games played.

(148*25)/(25+12)

Step-by-step explanation:

If two triangles are similar, the ratios of the side length to the corresponding side length  of the other must be the same for all sides

The first challenge is to figure out which side of triangle A corresponds to which side of triangle B

If you flip triangle A counterclockwise by 90° the angles will be aligned with each other and it is easier to see the corresponding sides of A and B

We see that ....

side length 24 of A matches with side length 18 of B

side length 36 of A matches with side length 27 of B

side length 32 of A matches with side length 24 of B

B is of smaller size than A so the scale factor of A to B is less than 1

26.

Therefore the scale factor of A to B is

[tex]\dfrac{18}{24} = \dfrac{27}{36} =\dfrac{24}{32}\\\\\\\dfrac{18}{24}= \dfrac{3}{4} \cdots \textrm { by dividing numerator and denominator by 6}[/tex]
