what is 7 1/2 divided by 2 1/4 equeal

Answers

Answer:

Mixed number: 3 1/3

Improper fraction: 10/3

Step-by-step explanation:

Answer:

3 1/3 or 10 / 3

Step-by-step explanation:

7 1/2 divided by 2 1/4 =

Multiply 7 by 2.

7 x 2 = 14

Add 1 to 14 because of the 1 in 1/2.

14 + 1 = 15

7 1/2 turns into 15 / 2.

Do the same for 2 1/4.

Multiply 2 by 4.

2 x 4 = 8

Add 1 to 8 because of the 1 in 1/4.

8 + 1 = 9

2 1/4 turns into 9 / 4.

15 / 2 divided by 9 / 4

KEEP CHANGE FLIP!!

15 / 2 x 4 / 9

15 x 4 = 60 & 2 x 9 = 18

15 / 2 x 4 / 9 = 60 / 18

Let's simplify 60 / 18 by dividing by the greatest common factor; 6.

60 / 6 = 10 & 18 / 6 = 3

10 / 3 = 3 1/3

The fraction a/b is in simplest terms and equal to the following:((2020^3)-1)/((2021^3)+1) . What is a + b?

Answers

Consider the expression

[tex]\dfrac{x^3-1}{(x+1)^3+1}[/tex]

Factorize the numerator and denominator a difference/sum of cubes:

[tex]\dfrac{(x-1)(x^2+x+1)}{((x+1)+1)((x+1)^2-(x+1)+1)}[/tex]

Expand the denominator:

[tex]\dfrac{(x-1)(x^2+x+1)}{(x+2)((x^2+2x+1)-(x+1)+1)}=\dfrac{(x-1)(x^2+x+1)}{(x+2)(x^2+x+1)}=\dfrac{x-1}{x+2}[/tex]

since x = 2020, and clearly 2020² + 2020 + 1 ≠ 0, so we can cancel the factor of x ² + x + 1. This leaves us with

[tex]\dfrac{2020^3-1}{2021^3+1} = \dfrac{2020-1}{2020+2} = \dfrac{2019}{2022}=\dfrac{673}{674}=\dfrac ab[/tex]

so that a + b = 673 + 674 = 1347.

Answer:

The idea behind correct deciphering of word problems is correct understanding of the words used in the question. Both literally and mathematically. “More than” implies that something is greater than something in a literal sense. In mathematics, “a” is “more than” “b”, would be written as a>ba>b. Here even the verb, “is” plays an important role in the formation of the mathematical expression. For example, “a is more than b” means a>ba>b and “a more than b” means a+ba+b.

The weight of an object above the surface of the earth varies inversely with the square of its distance to the center of the earth. If an object weighs 50 pounds when it is 3960 miles from the center of the earth, what would its weight be when it is 3975 miles from the center of the earth?

Answers

Answer:

W = K m / R^2    expresses weight of ojject

W2 / W1 = (R1 / R2)^2        ratio of W2 to W1

W2 = W1 * (3960 / 3975)^2 = 50 * .992 = 49.62 lbs

  sales person A demonstrates better performance in all of the ratios we computed

Step-by-step explanation:

A: sales per attempt = $3.3M/167 ≈ $19.8k

  sale value per sale made = $3.3M/109 ≈ $30.3k

  sales made per attempt = 109/167 ≈ 65%

I like to let a graphing calculator or spreadsheet do repetitive calculations. It is well worth the few minutes it takes to learn how to enter a formula into any of the available free spreadsheet programs. The Desmos graphing calculator is amazing in its versatility and usefulness.

There are a couple of things that can help make it easier to construct a table of values.

1) recognize the axis of symmetry for this quadratic is ...

  x = -b/(2a) = -25/(2(-5)) = 2.5

So, choosing numbers either side of t=2.5 will cut your work in half.

  h(2) = h(3)

  h(1) = h(4) . . . for example

2) use Horner form to make manual evaluation easier.

  h = (-5t +25)t +2  or  = (5 -t)(5t) +2

Answer:

the length would be 3ft and the width would be 2ft

Step-by-step explanation:

this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer

Answer:

LENGTH - 3cm / WIDTH - 2cm

Step-by-step explanation:

Well first off, you would use the scale: 1 cm = 4 ft

With 12, you divide by 4. 12 ÷ 4 = 3

With 8, you also divide by 4. 8 ÷ 4 = 2

So, it would be 3 cm long and 2 cm wide.

Answer:

An equation is 92 + 2x = 180.

The congruent angles each measure 44°.

Step-by-step explanation:

1. If two angles in a triangle are congruent and unknown, we can represent that as 2x. That means 92 + 2x = 180.

2. To find the measure of each congruent angle, x, we have to solve the equation above.

Step 1: Simplify both sides of the equation.

[tex]2x + 92 = 180[/tex]

Step 2: Subtract 92 from both sides.

[tex]2x + 92 - 92 = 180 - 92[/tex] [tex]2x = 88[/tex]

Step 3: Divide both sides by 2.

[tex]\frac{2x}{2} = \frac{88}{2}[/tex] [tex]x = 44[/tex]

x = 44 means that the congruent angles each measure 44°.

Answer: 92+2x=180

Step-by-step explanation:

180-92=88

88/2 = 44

The rectangular screen on a laptop has an area of 375 cm ^ 2 Its width is 10 cm less than its length. What are the dimensions of the screen?

Answers

Answer:

lenght = 25 cm

widht = 15 cm

Step-by-step explanation:

Dimensions of the screen

375 = (l - 10) × l

375 = l² - 10l

l² - 10l -375 = 0

(l + 15)(l -25)

l = -15 or l = 25

lenght = 25 cm

widht = 25 - 10

widht = 15 cm
