Answer:

10 envelopes

Step-by-step explanation:

What we know:

- There are 3 drawings for each envelope

- There are 28 drawings in total

To find out the number of envelopes Declan would need, we divide 28 by 3 (check the picture attached).

28÷3=9 R1

28 divided by 3 gives us 9 with a remainder of 1, which means if Declan had 9 envelopes, he would be able to fit 3 drawings in each with 1 drawing left over. He would need a 10th envelope to use for the last drawing.

Therefore, Declan would need 10 envelopes to mail all the drawings to his grandma.

I hope this helps! Happy holidays :)

Answer: 112.5

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

Answer:

the x-coordinate and y-coordinate change places.

Step-by-step explanation: so you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:

the new side lengths are 10.5 , 9 and 6 inches

the new triangle has the following sides: 5, 4, 3 inches

the perimeter of the first triangle is 36 inches

the perimeter of the second triangle is 12 inches

area of the first triangle is 54 inches squared

area of the second triangle is 6 inches squared

Step-by-step explanation:

first question:

sides are 7,6,4. multiply each one by 3/2 or 1.5

7 x 1.5 = 10.5 or 12/2

6 x 1.5 = 9

4 x 1.5 = 6

the new side lengths are 10.5 , 9 and 6 inches

second question:

multiply each side by 1/3

the sides are 15, 12, 9, so:

15 x 1/3= 5

12 x 1/3 = 4

9 x 1/3 = 3

the new triangle has the following sides: 5, 4, 3

normal sides are 3 and 4

hypotenuse is 5

question a: (calculate perimeter)

the perimeter of a triangle: you add all the sides

the first triangle has 15, 12, 9 for its sides so:

15+12+9 = 36

the perimeter of the first triangle is 36

the second triangle has 5,4,3 for its sides so:

5+4+3 = 12

the perimeter of the second triangle is 12

question b: (calculate the area of both triangles)

area of a triangle: h x b/2: height times base divided by 2

the first triangle has sides, 15,12,9

height is 9 and base is 12, so:

9 x 12/2 = 54 inches squared

area of the first triangle is 54 inches squared

the second triangle has sides, 5,4,3

height is 3 and base is 4, so:

3 x 4/2 = 6 inches squared

area of the second triangle is 6 inches squared

The number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.

Given that, the book they're reading right now is 256 pages long.

Let the number of days be x.

Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.

102+16x -------(i)

Bert has read 142 pages, and he plans to read 11 pages every day.

142+11x -------(ii)

Addison and Bert have each read the same number of pages in total.

So, (i)=(ii)

102+16x=142+11x

16x-11x=142-102

5x=40

x=8

Hence, the number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

I think i need to picture of the graph

From G to K the graph increases and then decreases

Answer:

(a) The amount of ice cream increase as temperature increases

(b)

\(y = 2x + 5\) --- equation

\(y = 5\) --- y intercept

\(m = 2\) --- slope

Step-by-step explanation:

Given

See attachment for graph

Solving (a): The relationship between the variables

From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.

In other words;

The amount of ice cream increase as temperature increases

Solving (b): The line of best fit

First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).

From (2), we select any 2 points on the line:

\((x_1,y_1) = (15,35)\)

\((x_2,y_2) = (0,5)\)

The slope (m) is:

\(m = \frac{y_2 -y_1}{x_2 - x_1}\)

\(m = \frac{5-35}{0-15}\)

\(m = \frac{-30}{-15}\)

\(m = 2\)

So, the line of best fit is:

\(y = m(x - x_1) + y_1\)

Substitute known values:

\(y = 2(x - 0) + 5\)

\(y = 2(x) + 5\)

\(y = 2x + 5\)

The y-intercept is when \(x=0\)

So, we have:

\(y = 2*0 + 5\)

\(y = 0 + 5\)

\(y = 5\)

The value of is equal to the length of the side of the larger square minus the sum of the lengths of the two segments.

The value of is equal to the length of the side of the larger square minus the sum of the lengths of the two segments. This is because the area of the smaller square inscribed in the larger square is equal to the product of the side lengths of the smaller square. If a vertex of the smaller square is located on the side of the larger square, the side of the larger square is divided into two segments with one segment having length and the other having length . The side length of the larger square is then equal to the sum of the lengths of the two segments plus the side length of the smaller square, which is . Therefore, the side length of the larger square minus the sum of the lengths of the two segments is equal to the side length of the smaller square, or the value of is equal to two segments.

Question:

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 pounds of the mixture while stirring the contents. The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture, and the leftover mixture is washed out of the mixing bucket.

What is the greatest number of bricks Lynn can make?  

How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest  number of bricks?

Answer:

Greatest number of bricks = 70

Washed out mixture = 4 pounds

Therefore, Lynn can make at most 70 bricks and 4 pounds of mixture will be washed out if she makes 70 bricks.

Step-by-step explanation:

She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket.

Amount of mixture = 39 pounds of water + 48 pounds of brick dust

Amount of mixture = 87 pounds

She spills 13 pounds of the mixture while stirring the contents.

Amount of mixture left = 87 pounds - 13 pounds

Amount of mixture left = 74 pounds

Each brick requires 7 pounds of mixture

What is the greatest number of bricks Lynn can make?  

Greatest number of bricks = 7×10

Greatest number of bricks = 70

How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest  number of bricks?

Washed out mixture = 74 pounds - 70 pounds

Washed out mixture = 4 pounds

Therefore, Lynn can make at most 70 bricks and 4 pounds of mixture will be washed out if she makes 70 bricks.

Let's place the triangle in a Cartesian Plane - see attached figure.

We have:

A(1; 2)

B(3; 1)

C(6; 3)

1 - rotation

Specifically for a 90° rotation, we will use the expression

then

A'(-2; 1)

B'(-1; 3)

C'(-3; 6)

2 - translation

For a translation, we will add n units in all coordinates. (instead of adding, we could too subtract)

Let's consider n = 2, so

A''(3; 4)

B''(5; 3)

C''(8; 5)

3 - reflection

No way. We have to draw the original figure and reflect it.  Let's use the Y axis as the reflection axis.

See the attachments

Answer:

See attachments.

Step-by-step explanation:

Rotation, translation and reflection are all examples of transformations  A transformation is a way by which the size or position of a shape is changed.

(See attachment 1)

Rotation turns a shape around a fixed point called the center of rotation.

(See attachment 2)

A translation moves a shape left, right, up or down.

Every point on the original shape is translated (moved) the same distance in the same direction.

(See attachment 3)

A shape can be reflected across a line of reflection.

Every point on the reflected shape is the same distance from the line of reflection as the corresponding points on the original shape.

The lines joining the points on the original shape and the corresponding points on the reflected shape are perpendicular to the line of reflection.

All three transformations have been drawn on one grid in attachment 4.

Answer:

Step-by-step explanation:

1. Use the Pythagorean theorem: a^2+b^2=c^2.

You are already given c (which is always the longest side of the triangle) and one of the legs, which can be either a or b.

2. Put the numbers into the equation and square them.

6^2+b^2=10^2

When you square the numbers, it becomes 36 + b^2 = 100.

3. Subtract 36 from both sides and take the square root of the difference.

b^2 = 64

\(\sqrt{64}\) = 8

Answer: 8cm

Step-by-step explanation: Let’s use the Pythagorean Theorem! 6^2+x^2=10^2

36+x^2=100

x^2=64

X=8

Answer:

x = 39

Step-by-step explanation:

∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.

2x + 12 = 90

2x = 78

x = 39

Answer:

55

Step-by-step explanation:

40+y+30+y=180

40+2y+30=180

70+2y=180

2y=110

y=55

Checking: 55+40+(55+30) = 55+40+55+30 = 180

The number of puppies per kids is 20 puppies.

Given that, there are 180 puppies in the shelter with 9 kids.

Number of puppies per kids = Total number of puppies/Number of kids

= 180/9

= 20 puppies

Therefore, the number of puppies per kids is 20 puppies.
