Answer:

Step-by-step explanation:

1. First, put together the information we have. Total = 121. Emily has 40% more than Carl, and Carl has 60% more than Antony.

2. Next, set each person as a variable. Antony = x. Carl = 1.6x. Emily = 1.4 times 1.6x.

3. Next, form an equation using these variables.

    x + 1.6x + (1.4 x 1.6x) = 121

    x + 1.6x + 2.24x = 121

    4.84x = 121

    x = 25

4. Finally, plug in x to our previous variables in step #2 to find the number of stamps Emily and Carl have.

Antony: x = 25 stamps

Carl: 1.6x = 40 stamps

Emily: 1.4 times 1.6x = 56 stamps

Answer:

(−1, –1.25), (5, –2.75)

Step-by-step explanation:

If "slope-intercept form" is mentioned, then we already know that the function rule is that of a straight line with slope m and y-intercept b.

As we go from (−1, –1.25) to (5, –2.75), x increases by 6 and y decreases by 1.50.  Thus, the slope, m, is m = rise / run = -1.50 / 6, or m = -0.25 or -1/4.

Choosing one of the given points at random:  (8, -3.5), we start with the slope-intercept form y = mx + b and substitute -1/4 for m, 8 for x and -3.5 for y:    y = mx + b  becomes  -3.5 = (-1/4)(8) + b.  Then -3.5 + 2 = b, or b = -1.5.

The desired equation is y = (-1/4)x - 3/2, or y = -0.25x - 1.5

To write a function rule in slope-intercept form for the given ordered pairs, we need to calculate the slope and find the y-intercept. The slope can be calculated using the formula (Y2 - Y1) / (X2 - X1), and the y-intercept can be found by using the point-slope form and substituting one of the ordered pairs. The function rule in slope-intercept form for the given ordered pairs is y = -0.25x - 1.5.

To write a function rule in slope-intercept form, we need to find the slope (m) and the y-intercept (b). Given the ordered pairs (–12, 1.5), (−1, –1.25), (5, –2.75), (8, −3.5), we can calculate the slope using the formula m = (Y2 - Y1) / (X2 - X1). Let's choose two ordered pairs to calculate the slope:

Using (–12, 1.5) and (−1, –1.25):

m = (-1.25 - 1.5) / (-1 - (-12)) = (-2.75) / (11) = -0.25

Now, we can use the point-slope form y - y1 = m(x - x1), where (x1, y1) is one of the ordered pairs and substitute the slope and one of the points to find the y-intercept:

Using the ordered pair (–12, 1.5):

y - 1.5 = -0.25(x - (-12))

y - 1.5 = -0.25(x + 12)

y - 1.5 = -0.25x - 3

y = -0.25x - 3 + 1.5

y = -0.25x - 1.5

Therefore, the function rule in slope-intercept form (fraction form) is y = -0.25x - 1.5.

Answer:

3/8

Step-by-step explanation:

the formula to find average of a set of values is, you add all the numbers, then you divide by the total amount of numbers.

you can work backwards with your problem by multiplying 1/4*2

[tex] \frac{1}{4} \times 2 = \frac{1}{2} [/tex]

then you subtract 1/8 from that

[tex] \frac{1}{2} - \frac{1}{8} = \frac{3}{8} [/tex]

3/8 is the other number to get an average of 1/4

Answer:

t+m=20--------> t=20-m

3t+11m=100

Substitute

3(20-m)+m=100

60m-3m+11m=100

Get rid of 60

-3m+11m=40

8m=40

Divide by 8

m=5

This tells us that there are 5 Multiple Choice questions. So the remaining 15 question on the test must be True/False questions.

If we got all 5 Multiple Choice questions correct we would score 11 points for each of the five questions and this would give us 55 points. Then if we got all 15 True/False questions correct at 3 points each, we would score 15 times 3 or 45 points. So the total number of points on the test would be 55 + 45 = 100.

Step-by-step explanation:

The answer is:

There are 15 true/false questions while there are 5 multiple choice questions.

To solve the problem, we need to write two equations using the given information.

We know that there are twenty (20) questions consisting of true/false and multiple choice questions, so, writing the first equation we have:

Let be the true/false questions "x" and the multichoice questions "y".

First equation,

[tex]x+y=20[/tex]

Also, we know that the true/false questions worth 3 points while the  multichoice questions worth 11 points making a total of 100 points for the total examen, so, writing the second equation, we have:

Second equation,

[tex]3x+11y=100[/tex]

Now, we have to isolate one of the variables in function of the other variable, so, from the first equation, we have:

[tex]x+y=20[/tex]

[tex]x=20-y[/tex]

Then, substituting "x" into the second equation, we have:

[tex]3x+11y=100[/tex]

[tex]3(20-y)+11y=100[/tex]

[tex]60-3y+11y=100[/tex]

[tex]60+8y=100[/tex]

[tex]8y=100-60=40[/tex]

[tex]y=\frac{40}{8}=5[/tex]

Then, substituting "y" into the first equation, we have:

[tex]x+y=20[/tex]

[tex]x+5=20[/tex]

[tex]x=20-5=15[/tex]

Hence, we have that there are 15 true/false questions while there are 5 multiple choice questions.

Let's prove that we are right by substituting the obtained answers into the both equations, if the equations are satisfied, the answers are ok.

Substituting into the first and the second equation, we have:

First equation,

[tex]x+y=20\\5questions+15questions=20questions\[/tex]

Second equation,

[tex]3x+11y=100points\\3*(15)+11*(5)=100points\\45points+55points=100points[/tex]

We can see that both equations are satisfied, so, the answers are ok.

Answer:

The base b is 6m

Step-by-step explanation:

The area A of a triangle with base b and height h is given by the formula;

[tex]A=\frac{1}{2}*b*h[/tex]

The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;

[tex]45=\frac{1}{2}*b*15\\\\90=15*b[/tex]

We finally divide both sides by 15 to solve for b;

b = 90/15 = 6

Therefore, the base of the triangle is 6 m

Answer:

[tex]b = 6\ m[/tex]

Step-by-step explanation:

The area of a triangle is

[tex]A = 0.5b * h[/tex]

Where b is the base of the triangle and ha is the height.

In this case we have a triangle with area

[tex]A = 45\ m ^ 2[/tex]

and with height:

[tex]h = 15\ m[/tex]

So the base of the triangle is:

[tex]45 = 0.5b (15)\\\\b=\frac{45}{15*0.5}\\\\b=6\ m[/tex]

Finally the base of the triangle is b = 6 meters

Answer:

-51, -41, -38, 13, 41, 50

Step-by-step explanation:

The integers ordered from least to greatest are: -51, -41, -38, 13, 41, 50.

To order the integers from least to greatest, one must start by identifying the negative integers and then the positive integers. Among negative integers, the larger the absolute value, the smaller the number. Conversely, for positive integers, the larger the number, the greater it is.

Starting with the negative integers:

-51 is the smallest because it has the largest absolute value among the negative numbers.

-41 is the next smallest negative number.

-38 is the smallest negative number because it has the smallest absolute value among the negatives.

Now, moving on to the positive integers:

13 is the smallest positive number.

41 is the next smallest positive number.

50 is the largest positive number.

Putting it all together:

-51, -41, -38, 13, 41, 50.

Answer:

A=13+B

Step-by-step explanation:

The explicit formula for an arithmetic sequence is:

[tex]a_n = n_1 + d(n-1)[/tex]

Where:

[tex]a_n[/tex] is the number of yards that Freya runs on the day

[tex]a_1[/tex] is the number of yards that he runs on day 1

d is the increase factor. [tex]d = 5[/tex] yards

n is the number of days

Answer:

First question

a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

y = 2x² + 4 ⇒ second answer

Third question

No of the choices correct ⇒ fourth answer

Step-by-step explanation:

First question

∵ f(x) = x² + 6

- It is a quadratic function with general form ax² + bx + c

- Its vertex is (h , k), where h = -b/2a and k = f(h)

∵ a = 1 , b = 0 , c = 6

∴ h = 0/2(1) = 0

∴ f(0) = 0² + 6 = 6

∴ a = 1 , h = 0 , k = 6 ⇒ third answer

Second question

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

∵ y = 2x²

∵ y is shifted 4 units up

∴ k = 4

∴ y + 4 = 2x² + 4

∴ y = 2x² + 4 ⇒ second answer

Third question

∵ y = -2x² + 3

- It is a quadratic equation with general form ax² + bx + c

- It represented graphically by parabola

- If a is positive the parabola opens upward

- If a is negative the parabola opens downward

∵ a = -2

∴ The parabola opens downward

∴ No of the choices correct ⇒ fourth answer

Answer:

A)3,9

Step-by-step explanation:

lets take the length as "x"

since the width is 3 times the length we can use 3x to represent the width

formula for perimeter: 2(l)+2(w)

2(x)+2(3x)=24

2x+6x=24

8x=24

8x/8=24/8

x=3

if x is 3, the length is 3

if x is 3, the width, 3x is 9, (3*3)

The dimensions of the rectangle are a length of 9 inches and a width of 3 inches, with the width being one-third of the length. This corresponds to option D (9, 3) in the list of given choices.

The length and width of the rectangle when the perimeter is 24 inches and the length l is 3 times the width w, we can set up equations based on the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

Given that l = 3w, we substitute this into the perimeter formula to get:
24 = 2(3w) + 2w24 = 6w + 2w24 = 8w
Dividing both sides by 8 to solve for w:
w = 3

Now that we know the width is 3 inches, we can find the length by multiplying the width by 3:
l = 3w = 3(3) = 9

So, the length is 9 inches, and the width is 3 inches, which corresponds to option D. Therefore, the dimensions of the rectangle are a length of 9 inches and a width of 3 inches.

Answer:

f(x) ⇒ Graph C

g(x) ⇒ Graph D

h(x) ⇒ Graph A

j(x) ⇒ Graph E

Step-by-step explanation:

* Lets revise the quadratic function and its inverse

- The quadratic function if f(x) = x², its vertex is the origin

- To find its inverse, switch x and y and solve for y

∵ y = x² ⇒ switch x and y

∴ x = y² ⇒ solve for y

∴ y = ± √x

- If y = √x , then the graph is up the x-axis

- If y = -√x , the graph is down the x-axis

∴ The inverse function is y = √x

* Now lets solve the problem

- All the figure are the inverses of the quadratic function y = x²

∵ f(x) = √(x - 1)

# x - 1 means the graph move to the right 1 unit

∴ Its vertex is (1 , 0)

* The graph of f(x) = √(x - 1) is graph C

∵ g(x) = -√x

# The sign (-) means the graph reflected about the x-axis

∴ Its vertex is (0 , 0) but the graph under the x-axis

* The graph of g(x) = -√x is graph D

∵ h(x) = √x

∴ Its vertex is (0 , 0)

- It is the inverse of y = x² , the graph up to the x-axis

* The graph of h(x) = √x is graph A

∵ j(x) = -√(x - 1)

# x - 1 means the graph move to the right 1 unit

# The sign (-) means the graph reflected about the x-axis

∴ Its vertex is (1 , 0) , the graph down the x-axis

* The graph of j(x) = -√(x - 1) is graph E
