Explanation:

Let's find the distance between the two given values

Let a = -2.8 and b = -7.2

Subtract a and b, then apply absolute value to ensure the result isn't negative.

|a-b| = |-2.8-(-7.2)|

|a-b| = |-2.8+7.2|

|a-b| = |4.4|

|a-b| = 4.4

The distance from -2.8 to -7.2 is 4.4 units.

To go from -2.8 to -7.2, we moved 4.4 units to the left.

Let's go back to -2.8 and now move 4.4 units to the right.

So we add 4.4 onto -2.8 getting

-2.8+4.4 = 1.6

The diagram is shown below.

On a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that two numbers on a number line that is:

-2.8 and -7.2

To find the other number that is the same distance from −2.8 as −7.2:

Mathematically, we can write a number expression:

= -2.8 -(-7.2)

= -2.8 + 7.2

= 4.4

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

Accordingly, -7.2 is 4.4 units distant from -2.8.

= -2.8 +4.4

= 1.6

Thus, on a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

Answer:

I think the first one is 8 and the other one is 7 I think

Answer:

40 units

Step-by-step explanation:

So first if it was a scale factor of 2.5 you would multiply it by 2.5 for each side. So for the side of 3 you would multiply it by 2.5 which is 7.5 so that side and the other side across from it would be 7.5 units. Then for the next one there is 5 units so you do the same 5x2.5 is equal to 12.5 so will the one below it.

Then it would be (7.5 * 2) + (12.5 * 2)= 15+25+40

So then the perimeter would be 40 units.

Answer:

24 baskets

Step-by-step explanation:

The GCF (greatest common factor) for 72, 96, and 48 is 24.

72/3 = 24

96/4 = 24

48/2 = 24

The greatest common factor of 72,96 and 48 is 24 so 24 baskets can be filled equally.

The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.

For example in 6 and 12 6 is the highest common factor.

Given that,

There are 72 cans of green beans, 96 cans of corn, and 48 cans of pumpkin.

The number of baskets that can be filled equally will be a number which is the greatest multiple of all three 72,48 and 24.

The HCF of 72,48 and 24 = 24 because it is the only the highest number through which all numbers can be divisible.

Hence "The maximum or greatest number of baskets will be 24 such that all three cans will be filled equally".

Answer:

8.8 in

Step-by-step explanation:

To find a circumference you need the diameter. To find the diameter you multiply the radius x2.


1.4x2=2.8

Tp get the circumference you multiply the diameter by pi or 3.14

The formula is [tex]\pi[/tex]d

so you multiply 2.8 by pi which is=8.79645943005 or to the nearest hundredth=8.8

Answer:

area = 50.27 sq inches

circumference = 25.14 in

Step-by-step explanation:

given radius r = 4 in

area = πr² = 3.142 x 4² = 50.27 square inches

circumference = 2πr = 2 x 3.142 x 4 = 25.14 inches

Answer: x² + 23x + 49

Step-by-step explanation:

The way to find the area of the shaded region is to find the area of the big rectangle, and subtract from it the area of the small square inside.

Simple enough! lets write it in algebra and work out the steps:

Area of Shaded = Area of big rectangle - Area of small square

Area of Shaded = [(x+10)(2x+5)]  -  [(x+1)(x+1)]

Area of Shaded = (2x² + 5x + 20x + 50)  -  (x² + x + x + 1)

Area of Shaded = (2x² + 25x + 50) - (x² + 2x + 1)

Area of Shaded = 2x² + 25x + 50 - x² - 2x - 1

Area of Shaded = 2x² - x² + 25x - 2x + 50 - 1

Area of Shaded = x² + 23x + 49

Answer:

The expression for the area of the shaded region is x² - 23x - 49

Step-by-step explanation:

Area of a rectangle

area = lw

where

l = length

w = width

Therefore,

The area of the shaded region  = area of the big rectangle - area of the small rectangle

Therefore,

area of the big rectangle = (x+10)(2x+5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50

area of the small rectangle = (x+1)(x+1) = x² + x + x + 1 = x² + 2x + 1

area of the shaded region = 2x² + 25x + 50 - ( x² + 2x + 1)

area of the shaded region =  2x² + 25x + 50 - x² - 2x - 1

area of the shaded region = x² - 23x - 49

8.36 is between 4 and 10

Answer:

between 4 and 10

Step-by-step explanation:

1.9 is almost 2.

4.4 is about 4.

2 × 4 = 8

So the answer should be between 4 and 10.

Note that 8 is not the answer of 1.9 × 4.4. We just estimated the value that could be the answer.

Answer:

42 feets

Step-by-step explanation:

We consider the right-angle triangle with B being the right-angle:

AB = 24 ft ; AC = 45 ft

We can use the Pythagorean theorem:

[tex]AB^{2} = AB^{2} + BC^{2} \\45^{2} = 24^{2} + BC^{2} \\BC^{2} = 2025 - 576\\BC = \sqrt{1449} = 38[/tex]

The distance between the wall and the ladder is 38 feet.

Pulling the ladder away from the wall is adding 4 feet to the distance between the wall and the ladder.

38 + 4 = 42

The ladder is now 48 feet away from the wall at its bottom.

The arithmetic mean of the given data set ( 12, 13, 23, 112 ) as a fraction in simplest form is 80/2.

Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.

Mean = Sum total of the number ÷ n

Where n is number of numbers

Given the sets;

12, 13, 23, 112

n = 4

First we add the numbers

12 + 13 + 23 + 112 = 160

Mean = Sum total of the number ÷ n

Mean = 160 ÷ 4

Mean = 80/2

Therefore the arithmetic mean of the given data set ( 12, 13, 23, 112 ) as a fraction in simplest form is 80/2.

The scatterplot that shows the strongest relationship between the variable x and the variable y is: “On a graph, points are grouped close together and decrease.” Hence, Option A is correct.

In a scatterplot, dots are used to show the values of two different numerical variables. An individual data point's values are indicated by the placement of each dot on the horizontal and vertical axes.

An example of a plot or mathematical diagram is a scatterplot, which uses Cartesian coordinates to show the values of typically two variables given a collection of data.

Two quantitative variables assessed for the same individuals are shown in a scatterplot along with their relationship. The horizontal axis displays the values of one variable, and the vertical axis displays the values of the other variable.

Therefore, Option A is correct.

Answer: 72 u^2

What we know:

How to solve:

We need to find the area of at least one of the triangles and double it. Then, we need to find the areas of both rectangles. Finally, we need to add these areas to find the total area. The final area will be represented in units squared (u^2)

Triangles

Set up equation                                                 A = 1/2(bh)

Substitute                                                           A = 1/2(4*3)

Simplify                                                               A = 1/2(12)

Solve                                                                   A = 6

Double                                                                     *2

                                                                           A = 12 u^2

Rectangles

Set up equation                                                 A = lh

Substitute                                                           A = (14)(3)

Simplify                                                               A = 42 u^2

Set up equation                                                 A = lh

Substitute                                                           A = [14-(4+4)](3)

Simplify                                                               A = (14-8)(3)

Simplify                                                               A = (6)(3)

Multiply                                                               A = 18 u^2

Total Area

Set up equation                                                 A = R1+R2+T

Substitute                                                           A = 42 + 18 + 12

Simplify                                                               A = 60 + 12
