Answer 1

Answer:

1 / 3^5

1/ 243

Step-by-step explanation:

3^4 ÷ 3^9

We know that a^b ÷ a^c = a^ ( b-c)

3 ^ ( 4-9)

3^ -5

We can rewrite this as a^-b = 1/ a^b

1 / 3^5

We know that 3^5 = 243

1/ 243

Answer 2

Answer:

The answer to the question provided is [tex] \frac{1}{243} [/tex] and [tex] \frac{1}{ {3}^{5} } [/tex].

What is the quotient of 2 ÷ 2/3?​

Answers

Answer:

The answer is 3! I believe.

Step-by-step explanation:

Hello! Step by step divide 2 by 2/3 which is 2 so

1
.3=
2.3

1*2
=6

2
= 2*3

2*1
=3

Dividing the two fractions is like multiplying the first fraction by value or reciprocal value of first fraction value of SECOND fraction. So find the reciprocal like reversing the numerator and denominator reciprocal of 2/3 is 3

Of the second fraction then multiply the two numerators. Again multiply the two decnominators so the next following step intermediate step canceling by a comma factor 2 gives 3.... in words- two divided by two thirds=three

Hope that helps!!! Answer=3

Chorally count by 2⁄3 starting at 6

Answers

Answer:

6/3+2/3= 8/3 = 2 2/3

8/3+2/3= 10/3 = 3 1/3

10/3+2/3=12/3 = 4

12/3+2/3=14/3 = 4 2/3

14/3+2/3=16/3 = 5 1/3

16/3+2/3=18/3 = 6

18/3+2/3=20/3 = 6 2/3

20/3+2/3=22/3 = 7 1/3

22/3+2/3=24/3 = 8

24/3+2/3=26/3 = 8 2/3

26/3+2/3=28/3 = 9 1/3

28/3+2/3=30/3 = 10

30/3+2/3=32/3 = 10 2/3

32/3+2/3=34/3 = 11 1/3

Answers

you should know: in all means in total, so simply you add everything up.

answer:

1 + 2/4 + 3/4

- convert 1 to a fraction so its easier to add.

1 = 4/4 (must have the same denominator to add)

4/4 + 2/4 + 3/4

- add the numerators (top), NOT the denominators (bottom)

you get: 9/4 (this is an improper fraction, so you convert this into a mixed number)

9/4 = 2 1/4

FINAL ANSWER: (its a mixed number)

2 1/4

Find the Dimensions of Rectangle ABCD

Perimeter of ABCD= 80

(Pythagorean Theorem)
Will mark brainliest!

Answers

Answer:

xy + 2x + 2y = (42)(80)

x2 + 80x - 42 = 0

x2 - 42x + 80 = 0

x2 - 21x + 80 = 0

Step-by-step explanation:

The dimensions of the rectangle ABCD is 24 x 16

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the dimensions of the rectangle be represented as L x W

where L and W are the length and width of the rectangle

The perimeter of the rectangle P = 80

Now , measure of side E F of triangle is given by the Pythagoras Theorem

And , E F = √ ( A F )² - ( E A )²

On simplifying the equation , we get

The measure of side E F = √ ( 625 - 400 )

The measure of side E F = √225 = 15

Now ,

The measure of side EC of triangle is given by the Pythagoras Theorem

And , EC = √ ( E F )² - ( C F )²

On simplifying the equation , we get

The measure of side E C = √ ( 15 )² - ( 9 )²

The measure of side E C = √ ( 225 - 91 )

The measure of side E C = √144

The measure of side E C = 12

So , the length of the rectangle B C = E B + B C = 12 + 12

The length of the rectangle B C = 24

The width of the rectangle is A B = W

Perimeter P of rectangle = 2 ( Length + Width )

Substituting the values in the equation , we get

80 = 2 ( 24 + W )

Divide by 2 on both sides of the equation , we get

24 + W = 40

Subtracting 24 on both sides of the equation , we get

W = 16

Hence , the dimensions of the rectangle is 24 x 16
