Given:

The sequence is 29, 22,​ 15, 8,​ 1, ...

To find:

The common difference.

Solution:

We have,

29, 22,​ 15, 8,​ 1, ...

It is an AP.

First term : [tex]a_1=29[/tex]

Second term : [tex]a_2=22[/tex]

Now,

Common difference : [tex]d=a_2-a_1[/tex]

[tex]d=22-29[/tex]

[tex]d=-7[/tex]

Therefore, the correct common difference is -7.

Note: Here calculation by student is not given, so we cannot find the error of the student.

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

The circumference of the Ferris wheel is the product of the diameter and [tex]\pi[/tex]

The circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]

The circumference of a circle, when the diameter is given is calculated using the following equation

C = [tex]\pi[/tex]d

The diameter of the Ferris wheel is given as:

d = 63 feet.

So, we have;

C = [tex]\pi[/tex] * 63

Rewrite as:

C =63 * [tex]\pi[/tex]

Hence, the circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]

Step-by-step explanation:

A triangle has a total of 180° (B is a 90° angle)

Take 180° - 90° to find the angle of A + C which equals 90°

take 90°/2 to get the angle of C which is 45°

and to check that take 45°+45°+90°= 180°

For Samantha, 2 tick marks east is 120 units east because 1 tick is 60 units.

For Ryu, 8 tick marks west is 480 units west because 1 tick is 60 units.

They are walking to form a line. Just add their distances from 0.

120 + 480 = 600.

Ryu: 480                         Samantha: 120

Answer:

498

Step-by-step explanation:

We will need to use the Pythagorean Theorem.

A^2 + B^2 = C^2

45^2 + B^2 = 500^2

Subtract 45^2

B^2 = 500^2 - 45^2

Simplify

B^2 = 247,975

Take square root so B is alone

B = 497.9708

Round

B = 498

Answer:

44.4°

Step-by-step explanation:

Two complementary angles add up to 90°. Let's call one of the two x, and the second 90-x (in fact, [tex]x+(90-x) = 90[/tex]).

At this point we can use the second condition: the first angle, plus 1.2°, is equal to the complementary.

[tex]x+1.2=90-x \rightarrow 2x=88.8 \rightarrow x = 44.4[/tex]

Answer:

For class A, the test scores were closer togther so that means more students most likely scored the smae score mutiple times. I think this because the box on the box plot is not spread out like class B.

For class B, the scores varied more so the box plot has to be spread out over more values. Because of the box plot, we can see that Class B had the highest test score compared to class A.

The constant of proportionality is 4.5

Step-by-step explanation:

To demonstrate the constant of proportionality, we typically use variable k. The equation can look like y/x=k or y=kx
y/x=k
9/2= 4.5

The constant of proportionality is 4.5.

To check the work, we can use the other equation, y=kx.

Step-by-step explanation:

Find the slope of the line between (5,5)and (1,0) using m=(y2-y1)/(x2-x1)

which is the change of y over the change of x.

m=5/4

Use the slope 5/4 and a given point (5,5) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=(y2-y1)/(x2-x1)

y-5=5/4*(x-5)

Simplify the equation and keep it in point-slope form y-5=5/4*(x-5)

Solve for y.

y=5x/4-5/4

Reorder terms.

y=5/4 x-5/4

List the equation in different forms.

Slope-intercept form: y=5/4 x-5/4

Point-slope form: y-5=5/4*(x-5)

Option C: Copying an angle

Step-by-step explanation:

Angle bisector is a line through an angle that will split that angle to 2 equal angles. Thus, option A is wrong as no angle is being split.

Copying an angle involves reproducing a particular angle in another construction. The image shows us that there is an attempt to reproduce the perpendicular angle of 90°. Thus, option B is correct.

Copying a line segment involves creating the exact size of line in another construction. The image doesn't depict that. Thus option C is wrong.

Perpendicular bisector is when we draw a perpendicular line through a horizontal one to divide it into 2 equal parts. This is not the case here. Thus, option D is wrong.

Answer:

18

Step-by-step explanation:

perimeter = sum of the lengths of the sides

perimeter = 5 m + 5 m + 2 m + 5 m + 1 m

perimeter = 18 m

Answer:

x=20

Step-by-step explanation:

Answer:

Step-by-step explanation:

2/5x + 4 = 1/5x + 8

(subtract 1/5x from both sides)

1/5x + 4 = 8

(subtract 4 from sides)

1/5x = 4

(multiply by 5 from both sides of the equation to isolate x)

x = 20

Answer:

500g

Step-by-step explanation:

since she brought 2 kg of sweets, and distributed to her classmates, that means we wil sustract 2 from 1,5 and that will be 0.5 or 500g

I hope I helped you! :)))

Answer:

500g

Step-by-step explanation:

She initially had 2 kg and gave away 1 kg 500 to her classmates

1000 g = 1 kg

500 g   = ?

500 g = half a kilogram

So, 1kg 500g is 1.5 kg

So, to get how much sweets were left with her, we subtract 1.5 kg from 2 kg.

2 - 1.5 = 0.5 kg

So, she was left with 0.5 kg or 500g of sweets

Frank's average speed is the rate of the distance traveled and the time

Frank's average speed is 6.58 miles per hour

The given parameters are:

Distance = 5.3 kilometers

Time = 30 minutes

The average speed is then calculated as:

Average speed = Distance/Time

Substitute known values

Average speed = 5.3km/30 minutes

Convert time to hours

Average speed = 5.3km/0.5 hour

Convert the distance to miles

Average speed = 3.29 miles/0.5 hour

Evaluate the quotient

Average speed = 6.58 miles per hour

Hence, Frank's average speed is 6.58 miles per hour
