Can someone help me please

The age of the person who entered the room is 26.

From the information, the ages of the people are

23 , 19 , 12 , 21 , 13. Therefore the addition of the ages will give 88.

When another person entered, the person enters the room, the mean age of the 6 people is now 19. Therefore, the total ages will be:

= 19 × 6

= 114

Therefore, the age of the last person will be:

= 114 - 88

= 26

Therefore, the age of the person who entered the room is 26.

Answer:

Step-by-step explanation:

(X,y) (x-6, y+4)

The transformation rule for the new  ΔR'S'T' is  (x, y) →  (x - 6, y + 4). The correct option is (c).

The graph of a function can be transformed by either shifting it in the right, left, up or down.

When the transformation is rightwards, the function becomes as f(x - a).

For left shifting it is f(x + a).

The given problem can be solved by using the rule of transformation as follows,

For the translation of 6 units left and 4 units up, it can be written as,

Suppose the coordinate of a vertex of ΔRST be given as (x, y).

Then, as per the rule the new coordinate of ΔR'S'T' is (x - 6, y + 4).

Hence, rule that best describes the transformation given in the problem is (x, y) →  (x - 6, y + 4).

Answer:

The fourth answer: A person's weight, w, on the moon is 1/6 her weight on Earth, e.

Step-by-step explanation:

The equation must be translated carefully into word form.

Her weight on Earth is represented by e.

"e x 1/6" into "1/6 her weight on Earth, e"

Her weight on the moon is represented by w.

"= w" into "A person's weight, w, on the moon is"

Another way to translate: 1/6 of a person's weight on Earth, e, is equal to her weight on the moon, w.

54  pages are needed to hold all of his cards , if  Ricky has 648 baseball cards he wants to put them in an album if each page of the album holds 12 cards

Ricky has 648 cards , and each page of the album holds 12 cards. Which means, if each page holds 12 cards; One page will hold 12 cards, the second page, another 12 cards and so on.

Hence, 2 pages will hold 12+12 cards which is 24 cards. 3 pages will hold, 12+12+12 = 36 cards

Now, to get how much pages will hold 648 cards, we divide 648 by 12

648/12= 54 pages

Hence, if  Ricky has 648 baseball cards he wants to put them in an album if each page of the album holds 12 cards then 54  pages are needed to hold all of his cards

Answer:

[tex]x+y=13\\10x+9y=122[/tex]

Jose worked on washing cars for 5 hours and on walking dogs for 8 hours.

Step-by-step explanation:

Given that:

Jose works for two summer jobs.

Earnings per hour by the first job i.e. by washing cars = $10

Earnings per hour by the second job i.e. by walking dogs = $9

Total number of hours worked = 13 hours (30 hours does not give us proper answer, it must be 13)

Total money earned = $122

To find:

System of equations to find the number of hours that Jose worked on each job?

Solution:

Let number of hours worked on washing cars = [tex]x[/tex] hours

Let number of hours worked on walking dogs = [tex]y[/tex] hours

As per the question statement, we can write the following system of equations:

[tex]x+y=13 ..... (1)\\10x+9y=122 ...... (2)[/tex]

Let us use the Elimination method to find the values of [tex]x[/tex] and [tex]y[/tex].

Multiplying the equation (1) by 10 and then subtracting the equation (2) from it:

[tex]y = 130 - 122 = 8\ hours[/tex]

Using the equation (1):

[tex]x = 5[/tex] hours

Therefore, Jose worked on washing cars for 8 hours and on walking dogs for 5 hours.

Three kinds of rigid transformations needed are horizontal translation, dilation and vertical translation to obtain f(x) = 7 · |x - 9| - 11.

In this problem we must find what kind of rigid transformations are done on the parent absolute value function to obtain the function g(x) = 7 · |x - 9| - 11. Rigid transformations are transformations applied on functions such that their Euclidean distances are conserved. There are several forms of rigid transformations:

After a quick inspection, we find that the final function is the result of horizontal translation, dilation and vertical translation:

Horizontal translation

f'(x) = |x - 9|

Dilation

f''(x) = 7 · |x - 9|

Vertical translation

f(x) = 7 · |x - 9| - 11

Answer:

Yes,it is a right triangle

Step-by-step explanation: use pythagorean theorem: 4.5^2+6^2=7.5^2

The measure 4.5 inches, 6 inches and 7.5 inches together form a triangle.

A triangle is a three-sided polygon that consists of three edges and three vertices.

To determine whether the triangle formed by joining the straws will be a right triangle

we need to check if it satisfies the Pythagorean theorem

Let us assume that the 7.5-inch straw is the hypotenuse of the triangle. We need to check whether the sum of the squares of the other two sides (4.5 inches and 6 inches) is equal to the square of the hypotenuse (7.5 inches).

Using the Pythagorean theorem, we have:

7.5² = 4.5² + 6²

56.25 = 20.25 + 36

56.25 = 56.25

The sum of the squares of the two shorter sides is equal to the square of the longest side.

The triangle formed by joining the 4.5-inch, 6-inch, and 7.5-inch straws satisfies the Pythagorean theorem and is therefore a right triangle.

Hence, the measure 4.5 inches, 6 inches and 7.5 inches together form a triangle.

Answer: I think it’s y = mx+b?

Step-by-step explanation: well if you really need it-

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

If I remember correctly, rate of change is basically slope.

So if you want, you can choose two points and use the slope formula. If you're lazy, or don't necessarily NEED to use the slope formula, then you can just choose two points and count the rise and run.

Slope = [tex]\frac{rise}{run}[/tex]

Rise = -2 (going down two)

Run = 3

Therefore the slope is:

[tex]-\frac{2}{3}[/tex]

Using linear functions, it is found that both snowman's will have the same height of 21 inches after 5 hours.

A linear function is modeled by:

y = mx + b

In which:

For this problem, we have that:

Hence the functions are given as follows:

They will have the same height when:

A(t) = B(t)

51 - 6t = 36 - 3t

3t = 15

t = 5.

The height will be of:

B(3) = A(3) = 51 - 6(5) = 21 inches.
