Mrs. Williamson is projecting a slide on the wall. The image on the slide is 1.25 inches by 1.5 inches. The image projected on the wall is 20 inches by 24 inches. What is the scale factor of the dilation?

Answers

Answer 1

Answer:

Scale factor is 1:16

Step-by-step explanation:

1.25 x 16 = 20

1.5 x 16 = 24

The image on the wall is 16 times bigger than the image on the slide,
that is why the ratio is 1:16

Answer:

Step-by-step explanation:

Area of composite figure

Figure 1:

length = 27 ft

Width = 24 ft

Area of figure1 = length * width

                        = 27 * 24

                        = 648 square feet

Area of figure II:

              length = 27 ft

              Widht = 32 ft

Area of figure II = 27 *32

                          = 864 square feet

Area of figure III:

    base = 18 ft

     height = 32 ft

[tex]\text{Area of triangle (figure III) = $\dfrac{1}{2}*base*height$}\\\\[/tex]        

                                            [tex]= \dfrac{1}{2}*18*32\\\\= 288 \ square \ feet[/tex]

The ceiling of Stacy's living room is a square that is 33 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 33 ft, but she doesn't know how long it is.

Solve for the length of the diagonal of Stacy's ceiling in two ways:

(a) Using the Pythagorean Theorem.

(b) Using trigonometry.

Round each answer to the nearest whole number and make sure to show all your work. (Hint: the answers should be the same!)

Answers

Answer:

47

Step-by-step explanation:

a)

a^2 + b^2 = c^2

33^2+33^2=c^2

2178=c^2

c=(nearest is 47)

b)

If you cut the square in half diagonally, it forms two right triangles with angle measures 90-45-45. You can use sin (opposite over hypotenuse) to find the length of the hypotenuse.  sin (45) would be 33/(hypotenuse length). From a trig chart, you can find that sin (45) is 1/sqrt(2), meaning that 33/x = 1/sqrt(2). This means that x=33sqrt(2), which is around 47.

The length of the diagonal of Stacy's ceiling is 46,7.

What is the Pythagoras theorem?

Pythagoras Theorem (also called Pythagorean Theorem) is an important topic in Mathematics, which explains the relation between the sides of a right-angled triangle.

The ceiling of Stacy's living room is a square that is 33 ft long on each side. Stacy knows the diagonal of the ceiling from corner to corner must be longer than 33 ft, but she doesn't know how long it is.

By using Pythagoras theorem;

[tex]\rm Hypotenuse ^2=33^2+33^2\\\\ Hypotenuse ^2=1089+1089\\\\ Hypotenuse ^2=2178\\\\ Hypotenuse =46.9\\\\[/tex]

By using trigonometry;

[tex]\rm Cos45=\dfrac{33}{d}\\\\d =\dfrac{33}{cos45}\\\\d=46.7[/tex]

Hence, the length of the diagonal of Stacy's ceiling is 46,7.

_ _X_

Answers

Answer:

95 x 6

or  96 x 5

Step-by-step explanation:

Solve by logic

If you examine the three numbers, you will see that 5 is the only factor of 10.

If we multiply 5 by an even number, we get a multiple of 10.

If we multiply 5 by an odd number, we get a multiple of 5.

Therefore, the 1-digit number must be 5 or 6, and the last digit of the 2-digit number must be 6 or 5.

This means that the first digit of the 2-digit number has to be 9.

So the options are:  95 x 6  and  96 x 5

Proof

56 x 9 = 504

59 x 6 = 354

65 x 9 = 585

69 x 5 = 345

95 x 6 = 570

96 x 5 = 480

Answers

Answer:

22.1666666667 ~ 22.17 (This should be rounded)

Step-by-step explanation:

The mean formula is to add all the numbers and then divide by the quantity or how many numbers were listed.

25+31+12+38+12+15/6 = mean

All the numbers added up should equal 133


You need to divide the sum by 6 since that is how many numbers that are in your data set.

The Mean of the Data set is 22.1666666667 which is approximately 22.17

A function f is odd and f(x)=x^2 for all x>0. Sketch the graph of this function and then write the rule of this function as a single formula.

Answers

We will see that we have a piecewise function:

f(x) = x^2   for x > 0.f(x) = -x^2  for x ≤ 0.

The graph can be seen at the end.

What is an odd function?

A function is odd when f(-x) = -f(x) for all the values of x in the domain of the function.

In this case, we know that:

f(x) = x^2   for x > 0.

Then, for the negative range, the sign must change (but the quadratic function is even). Then we define the function in the negative range as:

f(x) = -x^2  for x ≤ 0.

This is the odd function (a piecewise function) for the whole domain:

f(x) = x^2   for x > 0.f(x) = -x^2  for x ≤ 0.

The graph of the piecewise function can be seen below.

If you want to learn more about piecewise functions, you can read:

https://brainly.com/question/3628123

Answer:

[tex]f(x) =\frac{x^3}{|x|}[/tex]

Step-by-step explanation:

Being an odd function means that [tex]f(-x) = -f(x)[/tex].

Graphically, it means the function will be symmetric across the origin.

So, the graph will have to look like the shown graph.

This graph looks quite similar to the graph [tex]f(x) = x^3[/tex], so we can use that as our parent function.

To get the graph to equal [tex]x^2[/tex] for x>0, we must divide [tex]x^3[/tex] by x.

However, this will simply result in the function [tex]f(x) = x^2[/tex].

If we divide by the absolute value of x however, the graph will look as desired.

1. Mr. Samuel had 13 notes in his wallet. They consist of $1. $5 and $10 notes. The total amount of the notes adds up to $93. How many $10 notes are there in his wallet?​

Answers

Answer:

8 $10 notes

Step-by-step explanation:

I started by working it backwards. $93-$3 equals $90. So we have three of our 13 notes. We need ten more. Well the most $10 notes we can have is 8. if we had 8 $10 notes that would give us $80. $90-$80=10. We can take ten and divide it by five so we have 2 $5 notes.

So in total he would have 8 $10 notes, 2 $5 notes, and $3 one dollar notes which adds up to 13 notes
