(6 + 7) + 8 = 6 + (7 + 8)
which property of addition shows

Answers

Answer 1

Answer: Associative Property of Addition

Step-by-step explanation: The problem (6 + 7) + 8 = 6 + (7 + 8)

demonstrates the associative property of addition.

Notice that the addends, or the number we're adding,

are the same on both sides of the equals sign, 6 + 7 + 8.

The associative property of addition tells us that when we're adding more

than two numbers, the grouping of addends does not change the sum.

For example here, (6 + 7) gives us 13, and 14 + 8 gives us 21.

On the right side, (7 + 8) gives us 15, and 6 + 15 gives us 21.

So the sum is the same, regardless of which way we group the addends.

What is rectangular prism?

"It is a three-dimensional solid shape which has six faces that are rectangles."

Formula to calculate the volume of rectangular prism:

V = l w h, where l is the length, w s the width and h is the height of the  rectangular prism.

Given figure consists of two rectangular prisms.

For the smaller rectangular prism,

length(a) = 8 [tex]V_2= 8\times 5\times 5[/tex]cm, width(b) = 8 cm and height(h) = 1 cm

For the larger rectangular prism,

length(p) = 8 cm, width(q) = 5 cm and height(r) = 5 cm

Let [tex]V_1,V_2[/tex] represents the volume of the smaller and larger rectangular prisms respectively.

The volume of the smaller rectangular prism would be,

⇒ [tex]V_1=a\times b\times c[/tex]

⇒ [tex]V_1=8\times 8\times 1[/tex]

⇒ [tex]V_1=64[/tex] cu.cm.

The volume of the larger rectangular prism would be,

⇒ [tex]V_2=p\times q\times r[/tex]

⇒ [tex]V_2=8\times 5\times 5[/tex]

⇒ [tex]V_2 = 200[/tex] cu.cm.

The volume of the figure is:

= [tex]V_1+V_2[/tex]

= 64 + 200

= 264 cubic centimeters

The volume of the figure 264 cubic centimeters.

the number of PI is 3.14 why do we use a special symbol for it​

Answers

Because 3.14 is only an estimation, pi is actually a never ending number, and so far we have only discovered so many digits (which you can google). We use 3.14 for equations that don’t need to be exact, and the symbol to represent the actual number, meaning it will be more accurate.

Which of the following is a rational number? (4 points)

square root 97square root 98, square root 99, square root 100

Answers

Answer:

Square root 100

Step-by-step explanation:

A rational number is a number that can be completely expressed by a fraction. In this case, 100 is the only square number so only the square root of 100 will result in a rational number (10) or (10/1). The others are not square numbers so square rooting them will result in a long line of decimal points which cannot be expressed by a fraction.

Hope this helped!

Answer:

The square root of 100 is a rational number.

Step-by-step explanation:

The square root of 100 is 10. A rational number is a number that can be made by dividing two integers (whole numbers). 10 ÷ 1 = 10. None of the other options are integers, so they are out.

Calculate the minimum and maximum possible areas. Round your answers to the nearest whole square unit. A rectangular garden plot measures 12 feet by 28.6 feet. The minimum possible area is about ft. The maximum possible area is about ft?​

Answers

Answer:

i. Minimum is 343 square feet

ii. Maximum is 360 square feet

Step-by-step explanation:

The dimension of the rectangular garden plot is 12 feet by 28.6 feet.

1. The minimum possible area can be determined by;

area of a rectangle = length x width

                               = 28.6 x 12

                               = 343.2

The minimum possible area is about 343 square feet.

2. The maximum value can be determined by;

             28.6 ≅ 30.0 (1 sf)

area of a rectangle = length x width

                                = 30 x 12

                                = 360

The maximum possible area is about 360 square feet.

The Sports Brand Company is making a new shoe that has a wholesale price of $40, and it wishes to advertise a retail price of $89.99. What is the markup percentage? Give answer to nearest whole percent. (hint: change decimal to percent, % will not be typed)

Answers

Answer:

Markup Percentage = 125%

Step-by-step explanation:

The wholesale price is $40, the "selling price" is $89.99.

90-40=50 (Profit)

Now that we know the profit , we need to find the percentage.

To find this percentage we can use the formula: (M=Markup percent)

[tex]M=profit/cost*100%[/tex]

In this situation, we can insert PROFIT= 50, Cost=40

M=50/40*100

= 1.25*100

=125%

=> 9x = 2268

Dividing both sides by 9

=> x = 252

So, The other number is 252.

Terry is filling spherical water balloons with a faucet that puts out 100cm^3 of water per second. At that rate, it takes Terry 6 seconds to fill a balloon.

What is the radius of a filled balloon?
Round to the nearest centimeter.

Answers

Answer:

To the nearest centimeter

Radius= 5 cm

Step-by-step explanation:

Rate of filling balloon= 100cm³/s

Time to feel the balloon= 6 s

Volume of the filed balloon

Answers

Answer:

Step-by-step explanation:

Given the order of operations A set of three scores to consists of the values 6, 3, and 2, we are to evaluate the following

1) Σ2X – 2

= 2(6)+2(3)+2(2) – 2

= 12+6+4–2

= 22–2

= 20

2) Σ(2X)² = (2×6)²+(2×3)²+(2×2)²

Σ(2X)² = 12²+6²+4²

Σ(2X)² = 144+36+16

Σ(2X)² = 144+52

Σ(2X)² = 196

The results of the order of operations are: [tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]

The scores are given as:

x = 6, 3 and 2

(a) The first set of operation

This is represented as:

[tex]\sum 2x -2[/tex]

So, we have:

[tex]\sum 2x -2 = 2 \times 6 - 2 + 2 \times 3 - 2 + 2 \times 2 - 2[/tex]

Evaluate the products

[tex]\sum 2x -2 = 12 - 2 + 6 - 2 + 4- 2[/tex]

[tex]\sum 2x -2 = 16[/tex]

(a) The second set of operation

This is represented as:

[tex]\sum (2x)^2[/tex]

So, we have:

[tex]\sum (2x)^2 =(2 \times 6)^2 + (2 \times 3)^2 + (2 \times 2)^2[/tex]

Evaluate the products

[tex]\sum (2x)^2 =12^2 + 6^2 + 4^2[/tex]

Evaluate the squares

[tex]\sum (2x)^2 =144 + 36 + 16[/tex]

[tex]\sum (2x)^2 =196[/tex]

Hence, the results of the order of operations are:

[tex]\sum 2x -2 = 16[/tex] and [tex]\sum (2x)^2 =196[/tex]

Why does the problem of finding the zeros (i.e. the inputs where a function assumes the value zero) receive such disproportionate attention in algebra?A. Because the problem of finding where a function f assumes the value c, i.e. solving f(x) = c, is equivalent to finding where the function f(x)-c assumes the value zero; and c = O is the only number for which f(x) = c can be solved by factoring f(x). B. It's because usually you want to know where a function crosses the x-axis. Crossing a different axis parallel to that is just not that interesting. C. It's because knowing the zeros allows you to determine the end behavior of the function, and the vertical and horizontal asymptotes. D. Because O is the lowest value (i.e. the minimum) that a function can assume. In many math applications, we need to know the minimum value of a quantity.

Answers

Answer:

The answer is C

Step-by-step explanation:

Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?

(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.

The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.

Finda + b, 2a + 3b, |a|, and |a − b|.a = 5i + j, b = i − 2j

Answers

Answer:

Step-by-step explanation:

Given the complex notations a = 5i + j, b = i − 2j, we are to evaluate the following:

1) a + b

= 5i+j + (i-2j)

= 5i+j+i-2j

collect like terms

= 5i+i+j-2j

= 6i-j

Hence a+b = 6i-j

2) 2a+3b

= 2(5i+j) + 3(i-2j)

open the parenthesis

= 10i+2j+3i-6j

collect like terms

= 10i+3i+2j-6j

= 13i-4j

Hence 2a+3b = 13i-4j

3) |a| = √x²+y²

Given a = 5i+j; x = 5, y = 1

|a| = √5²+1²

|a| = √25+1

|a| = √26

4) |a-b|

First we need to calculate a-b

=  a - b

= 5i+j - (i-2j)

open the parenthesis

= 5i+j-i+2j

collect like terms

= 5i-i+j+2j

= 4i-3j

|a-b| = √4²+(-3)²

|a-b| = √16+9

|a-b| = √25

|a-b| = 5
