Answer:

53 sweets.

Step-by-step explanation:

The mean out of 10 bags of sweets is 42. That means that all the numbers of sweets added up would be 420.

39 + 40(2) + 41(5) + 43 + x = 420

39 + 80 + 205 + 43 + x = 420

367 + x = 420

x = 53.

So, in the 10th bag, there are 53 sweets and a sugar high for whoever eats that many sweets.

Hope this helps!

Answer:

2 photographs

Step-by-step explanation:

338 devided by 4 is 84.5, so then 4 x 84 is 336 leaving 2 photographs as the remainder

Answer:

2 photos on the last page

Step-by-step explanation:

Notice that  4 times 84 is 336, so in 84 pages he can get 336 photographs, there are just 2 left to complete the 338 he had. So the last page gets 2 photos.

Answer:

f(1) = -11

f(n) = f(n-1) +3  n=2,3,4,5

Step-by-step explanation:

-11,-8,-5,-2,1,....

We are adding 3 each time

-11 +3 = -8

-8+3 = -5

f(1) = -11

Take the previous term and add 3

f(n) = f(n-1) +3  n=2,3,4,5

Answer:

x< 2 2/3

Step-by-step explanation:

5/8 X -1/3 < 1 1/3

Add 1/3 to each side

5/8 X -1/3+1/3 < 1 1/3+1/3

5/8x < 1 2/3

Change to an improper fraction

5/8 x < 5/3

Multiply each side by 8/5 to isolate x

8/5 * 5/8x  < 5/3 * 8/5

x < 8/3

Changing back to a mixed number

x< 2 2/3

Step-by-step explanation:

Under a rotation about the origin of 90°

a point (x, y ) → (- y, x )

The solution is, :A triangle is rotated 90° about the origin, then, (x, y) - (y, -x), this rule describes the transformation.

A transformation is a dramatic change in form or appearance. An important event like getting your driver's license, going to college, or getting married can cause a transformation in your life. A transformation is an extreme, radical change.

here, we have,

Rotation is a process in which the orientation of a given figure is changed by turning it about a point called origin.  The rotation can be done either clock-wisely or counterclockwise about the origin.

If the given triangle is rotated 90° clockwise, the rule that describe the transformation is; (x, y) - (y, -x)

If the given triangle is rotated 90° counterclockwise, the rule that describe the transformation is; (x, y) - (-y, x)

In the given question, the required rule is; (x, y) - (y, -x). This shows a clockwise rotation of 90° about the origin.

Hence, The solution is, :A triangle is rotated 90° about the origin, then, (x, y) - (y, -x), this rule describes the transformation.

[tex] \boxed{ \sf Rose's \ height = 1.5 \ m \ \ \ OR \ \ \ 150 \ cm} [/tex]

Given:

Cole's height = 1.7 m

Rose's height = 20 centimetres shorter than Cole

To Find:

Rose's height

Step-by-step explanation:

[tex]\sf 1 \ m = 100 \ cm \\ \\ \sf So, \\ \sf 1.7 \ m = 1.7 \times 100 \ cm \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 170 \ cm[/tex]

[tex]\therefore \ \sf Cole's \ height = 170 \ cm \\ \\ \sf \implies Rose's \ height = Cole's \ height - 20 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 170 - 20 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 150 \: cm[/tex]

[tex]\sf 1 \ cm = \frac{1}{100} \ m \\ \\ \sf So, \\ \sf 150 \ cm = 150 \times \frac{1}{100} \ m \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf = \frac{150}{100} \:m \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf = 1.5 \: m[/tex]

[tex]\therefore \ \sf Rose's \ height = 1.5 \ m[/tex]

Using algebra, Rose's height in centimeters is calculated as: 150 centimeters.

Let's use algebra to find Rose's height in centimeters based on the given information.

Let's assume Rose's height in centimeters is represented by "R".

We know that Cole is 1.7 meters tall, which is equivalent to 170 centimeters.

According to the given information, Rose is 20 centimeters shorter than Cole. So, we can set up the equation:

R = 170 - 20

Simplifying the equation:

R = 150

Therefore, Rose's height in centimeters is 150 centimeters.

Answer:

- Inverse Variation

- Equation: [tex]XY = 12[/tex]

Step-by-step explanation:

Given

X-> 2 | 4 | 8 | 12

Y-> 6 | 3 | 3/2 | 1

Required

- State the type of variation the table represents

- Determine the equation to model the data

To check for type of variation; we'll make use of trial by error method.

To start with; We'll check for direct variation.

This is done using the following expression;

[tex]Y = kX[/tex]where k is the constant of variation

Make k the subject of formula

[tex]k = \frac{Y}{X}[/tex]

When Y = 6, X= 2

[tex]K = \frac{6}{2} = 3[/tex]

When Y = 3, X = 4

[tex]K = \frac{3}{4}[/tex]

There's no need to check further as both values of k are not equal

To check for inverse variation;

[tex]Y = \frac{k}{X}[/tex]

Make k the subject of formula

[tex]k = YX[/tex]

When Y = 6, X= 2

[tex]K = 6 * 2 = 12[/tex]

When Y = 3, X = 4

[tex]K = 3 * 4 = 12[/tex]

When Y = 3/2; X = 8

[tex]K = \frac{3}{2} * 8 = \frac{24}{2} = 12[/tex]

When Y = 1, X = 12

[tex]K = !2 * 1 = 12[/tex]

Note that for all values of X and Y, K remains constant;

Hence, the table represents an inverse direction

To determine the equation;

We make use of  [tex]k = YX[/tex]

Substitute 12 for k

So, the equation becomes

[tex]12 = XY[/tex]

Reorder

[tex]XY = 12[/tex]

Hence, the equation is [tex]XY = 12[/tex]

Answer & Step-by-step explanation:

For this problem, we will be using the tangent trig ratio because we are dealing with the opposite side and the adjacent side of the triangle. Although cosine may be a good ratio to use as well, it is not the best ratio to use because if you were to use the cosine ratio, you will have more steps to complete in order to solve the problem. Plus, we are not dealing with the hypotenuse side of the triangle. Therefore, it is best to use the tangent ratio because it is more efficient and it corresponds to the side lengths we are using.

On the next page, we are given a Venn Diagram. We are asked to tell the difference between finding the angle and finding the side. Then, we are asked to find the similarity between them.

When solving for the unknown side, you have to flip the equation because one of the sides will be known as a variable.

When solving for the unknown angle, you have to use the inverse of the trig ratio that you are using for that problem.

The similarity between the two is that they will always use one of the trig ratios.

B. 30 in

Step-by-step explanation:

The circumference is pi d.

30 pi = pi d

30 pi / pi = d

30 = d

Answer:

Step-by-step explanation:

Suppose that the side length is s.  Imagine that one side is level.  Draw a vertical line through the top vertex perpendicular to the base (level side).  Label this vertical line "h."  Then h and s are related as follows:

                               √3          h

sin 60 degrees = ------- = --------

                                 2           s

                                                                   s√3

and so h = the height of the triangle =  -----------

                                                                       2

The area of this triangle is (1/2)(base)(height), which here is:

(1/2)(s/2)( s√3 /2), or

        (s^2)√3

A = ---------------

               8                                

Answer:

40°

Step-by-step explanation:

The triangle is a right triangle, so one measure of one of the angles is 90 degrees.

One acute angle measures 50 degrees.

Angles in a triangle add up to 180 degrees.

180 - 90 - 50

⇒ 40

The measure of the other acute angle is 40 degrees.

Acute angles measure less than 90 degrees. 40 degrees is less than 90 degrees, so it is an acute angle.

The measure of the other acute angle is 40°.

Given that, in a right triangle, one acute angle measures 50°.

A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.

Let the measure of other acute angle be x.

Using angle sum property of a triangle, we get

90°+50°+x=180°

⇒ x=180-140

⇒ x=40°

Therefore, the measure of the other acute angle is 40°.
