Plz help me I’m behindddd

Answers

Answer 1

Answer: A; r = square root (S/4pi)

Step-by-step explanation:

1. Divide 4pi on both sides to get r^2 by itself so the left side becomes S/4pi (you do this because 4, pi, and r^2 are being multiplied together on the right side in the original equation so to cancel that out and get r by itself you do the opposite of multiplication)

The equation should now look like r^2 = S/4pi

2. Square root both sides including r to get rid of the r^2 so it becomes just r (also when you square root both sides, you square root all of S/4pi not just S or 4pi but the whole thing)

After you do that, you get r = square root (S/4pi) which is answer A

Hope this helps! :)

find the scale factor of a drawing if the scale is 1 inch = 1/8 inch

Answers

Answer:

I believe that the answer is 8 because you have 1 inch =1/8 inch since you need eight 1/8 inches to equal one whole inch, it should be 8 inches

Step-by-step explanation:

The scale factor of the drawing if the scale is 1 inch = 1/8 inch is

What is Scale Drawing?

A scale drawing is a drawing made by enlarging or reducing the size of the original object.

The factor by which the drawing is enlarged or reduced is called the scale factor.

Given that,

Scale of a drawing is,

1 inch = 1/8 inch

That is, a drawing is drawn for which it is drawn 1/8 inch for actual dimension of 1 inch.

So, drawing is reduces by 1/8

So scale factor = 1/8

Hence the scale factor of the drawing is 1/8.

Antonio has $350 to spend on skis. Sales tax is 6%. Decide if each description of a price and discount, plus sales tax, represents a pair of skis that Antonio can purchase with the money he has. Choose yes or no for each description.

Answers

Answer: See explanation

Step-by-step explanation:

Antonio has $350 to spend on skis. sales tax is 6%. decide if each description of a price and discount, plus sales tax, represents a pair of skis that antonio can purchase with the money he has. choose yes or no for each description. a. 25% off $450 b. 20% off $385 c. $20 off $360 d. 15% off $360 e. $10 off $340.

The amount of money that Antonio can spend will be:

= $350 - (6% × $350)

= $350 - (0.06 × $350)

= $350 - $21

= $329

a. 25% off $450

= $450 - (25% × $450)

= $450 - (0.25 × $450)

= $450 - $112.50

= $337.50

b. 20% off $385

= $385 - (20% × $385)

= $385 - (0.2 × $385)

= $385 - $77

= $308

Yes

c. $20 off $360

= $360 - $20

= $340

d. 15% off $360

= $360 - (15% × $360)

= $360 - $54

= $306

Yes

e. $10 off $340

= $340 - $10

= $330

No.

Based on the $329 that Anthony has, he can make purchases on:

b. 20% off $385

d. 15% off $360

Identify the two factors that were multiplied together to form the array of tiles. Then identify the product of the two factors. Use the variable x in your expressions.

Answers

Answer:

[tex]Terms: 3\ and\ x + 2[/tex]

[tex]Product = 3x + 6[/tex]

Step-by-step explanation:

See attachment for complete question.

From the attachment, there are 3 columns and 3 rows

The 3 columns represent the first factor

To get the second factor, we have to analyze the 3 rows in the attachment.

Notice that the first row is bigger than the other two rows.

This big row will be represented with variable x

Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.

This is represented with + 1

Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.

This is also represented with + 1

Hence, the expression for the rows is x + 1 + 1 = x + 2

The product is then calculated as:

[tex]Product = 3 * (x + 2)[/tex]

[tex]Product = 3 * x + 3*2[/tex]

[tex]Product = 3x + 6[/tex]

What’s the solution of x+y=29 and y=4x-11

Answers

Answer:

x = 8

y = 21

Step-by-step explanation:

y = 4x − 11

x + y = 29

Solve for x:

x + y = 29

x + 4x − 11 = 29

5x − 11 = 29

5x = 40

x = 8

Solve for y:

y = 4x − 11

y = 4 × 8 − 11

y = 21

Triangles DEF and GHI are shown. Which sequence of rotations, reflections, and/or translations would map triangle DEF onto triangle GHI?

Does mapping triangle DEF onto triangle GHI prove the two triangles are congruent? Explain your reasoning.

Answers

Answer:

Part A:

The sequence of transformation that maps triangle DEF to triangle GHI are;

1) A reflection across the y-axis (x, y) →(-x, y) and

2) A translation 6 units down, (-x, y - 6)

Part B:

1) Yes

2) The points of the triangle GHI obtained from the mapping of triangle DEF using the given transformation are corresponding therefore, the mapping proves that the two triangles are congruent

Step-by-step explanation:

Part A:

The given coordinates of the vertices of triangle DEF are;

F(-1, 5), D(-5, 2), and E(-3, 1)

The given coordinates of the vertices of triangle IHG are;

I(1, -1), H(3, -5), and G(5, -4)

Therefore, the transformation that maps ΔDEF to ΔGHI are

1) A reflection across the y-axis (x, y) →(-x, y) and

2) A translation 6 units down, (-x, y - 6)

Reflection of point F(-1, 5) across the y-axis gives → (1, 5)

Followed by a translation 6 units down gives;

(1, 5) →T(y - 6) → I(1, -1)

Reflection of point D(-5, 2) across the y-axis gives → (5, 2)

Followed by a translation 6 units down gives;

(5, 2) →T(y - 6) → G(5, -4)

Reflection of point E(-3, 1) across the y-axis gives → (3, 1)

Followed by a translation 6 units down gives;

(3, 1) →T(y - 6) → H(3, -5)

Part B:

1) Yes mapping triangle DEF onto triangle GHI proves that the two triangles are congruent

2) The points of the triangle GHI obtained from the mapping of triangle DEF are the same, therefore, the mapping proves that the two triangles are congruent
