What is y in 16y = 36?

Mathematics
2 answers:
Marrrta [24]3 years ago

Answer:

9/4

Step-by-step explanation:

16y = 36

divide both sides by 16

y = 36/16

36/16 can be simplified to 9/4 (by dividing numerator and denominator both by 4)

= 9/4

Answer:

Y=2.25

Step-by-step explanation:

16y=36

16y is multiplication so to undo multiplication you need to divide

16 ➗ 16 gets the y by itself

36 ➗ 16 equals 2.25

so Y=2.25

You could check by doing 16 times 2.25 which is 36

What is the numb bur 731,934,000 in standard form
vesna_86 [32]
That number is already in standard form.

If you need to write it in scientific notation, then do this.

<span>731,934,000

Look at all the digits that are not zero, and place the decimal point in a way that you have a number from 1 to less than 10.

Take 731934, and place the decimal point after the 7 giving 7.31934.

The original decimal point was after the third zero, so now using the original number, count the number of decimal places you moved the decimal point. The decimal point moved 8 places to the left. That means you need an exponent of 8.

731,934,000 = 7.31934 \times 10^8

3^-6 x (3^4 / 3^0)^2
inna [77]

Answer:

9 x

Step-by-step explanation:

Simplify the following:

((3^4/3^0)^2 x)/(3^6)

Hint: | Compute 3^6 by repeated squaring. For example a^7 = a a^6 = a (a^3)^2 = a (a a^2)^2.

3^6 = (3^3)^2 = (3×3^2)^2:

((3^4/3^0)^2 x)/((3×3^2)^2)

Hint: | Evaluate 3^2.

3^2 = 9:

((3^4/3^0)^2 x)/((3×9)^2)

Hint: | Multiply 3 and 9 together.

3×9 = 27:

((3^4/3^0)^2 x)/(27^2)

Hint: | Evaluate 27^2.

| 2 | 7

× | 2 | 7

1 | 8 | 9

5 | 4 | 0

7 | 2 | 9:

((3^4/3^0)^2 x)/729

Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 3^4/3^0.

Combine powers. 3^4/3^0 = 3^(4 + 0):

((3^4)^2 x)/729

Hint: | For all positive integer exponents (a^n)^m = a^(n m). Apply this to (3^4)^2.

Multiply exponents. (3^4)^2 = 3^(4×2):

(3^(4×2) x)/729

Hint: | Multiply 4 and 2 together.

4×2 = 8:

(3^8 x)/729

Hint: | Compute 3^8 by repeated squaring. For example a^7 = a a^6 = a (a^3)^2 = a (a a^2)^2.

3^8 = (3^4)^2 = ((3^2)^2)^2:

(((3^2)^2)^2 x)/729

Hint: | Evaluate 3^2.

3^2 = 9:

((9^2)^2 x)/729

Hint: | Evaluate 9^2.

9^2 = 81:

(81^2 x)/729

Hint: | Evaluate 81^2.

| | 8 | 1

× | | 8 | 1

| | 8 | 1

6 | 4 | 8 | 0

6 | 5 | 6 | 1:

(6561 x)/729

Hint: | In (x×6561)/729, divide 6561 in the numerator by 729 in the denominator.

6561/729 = (729×9)/729 = 9:
