What is 21x^6y^5 divided by 14x^y^9 will make brainliest lot of points on the line too

Answers

Answer 1

Answer:

The simplified expression is: (3/2) x⁵ * (1/y⁴), or (3x⁵) /(2y⁴).

What is indices?

Indices, in mathematics, refer to the small numbers or symbols (exponents) used to indicate the power or exponent to which a number is raised, often in the context of exponents or powers.

To divide the expression (21x⁶y⁵) by (14x¹y⁹), simplify by subtracting the exponents of like terms:

(21x⁶y⁵) / (14x¹y⁹) = (21/14) * (x⁶⁻¹ * (y⁵⁻⁹))

Now simplify each part:

121/14) simplifies to (3/2)

x⁶⁻¹ simplifies to x⁵

3. y⁵⁻⁹ simplifies to y⁻⁴

So, the simplified expression is

(3/2) x⁵ * (1/y⁴), or (3x⁵) / (2y⁴).

Answer 2

Answer:

Answer:

$(3x^4)/(2y^4)$

Step-by-step explanation:

$(21x^6y^5)/(14x^2y^9)= \n\n\n(21)/(14)\cdot (x^6)/(x^2) \cdot (y^5)/(y^9)= \n\n\n(3x^4)/(2y^4)$

Hope this helps!

A trailer is rented at $30 per day plus a charge per mile of use. The trailer traveled 25 miles in one day, and the total charge was $130. Which equation can be used to find the charge x, in dollars, per mile traveled?30x + 25 = 130

30x + 25x = 130

30 + 25x = 130

30 + 25 = 130x

Jake wants to enlarge his 12-foot by 14-foot garden. If he multiplies the dimensions by 2, how will the area of the garden be affected?

Answers

Area = L*W
Original Area = 12*14 = 168
Multiply the dimensions by 2 = 12*2 = 24 and 14*2 = 28
New Area = 24 *28 = 672

New Area divided by original area = 672/168 = 4

The garden will be 4 times bigger in area

The standard deviation of a sample taken from population A is 17.6 for a sample of 25. The standard deviation of a sample taken from population B is 21.2 for a sample of 30. The standard deviation of the sample mean difference is?

Answers

The answer is 5.5

The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)

For the population A:
sd₁ = 17.6
n₁ = 25

For the population B:
sd₂ = 21.2
n₂ = 30

Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
= √(17.6²/20 + 21.2²/30)
= √(309.76/20 + 449.44/30)
= √(15.49 + 14.98)
= √(30.47)
= 5.5

Need help. 35-(-55)=?

Answers

the answer is 90.Remember that whenever you see two - signs right next to eachother it turns into an addition sign

Remember that subtracting a negative number is the same as adding a positive number.(two negatives equals a positive) For example:

35-(-55)=35+55

They are both equivalent. Now we can solve..

35+55=90

Answer=90
