Answer:

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]

Hence, ption B is true.

Step-by-step explanation:

Given the expression

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]

solving the expression

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]

as

[tex]\sqrt{x^2y^3}=xy\sqrt{y}[/tex]

[tex]2\sqrt{x^3y^4}=2xy^2\sqrt{x}[/tex]

so the expression becomes

[tex]\:\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}[/tex]

Group like terms

                                        [tex]=2xy^2\sqrt{x}+xy\sqrt{y}+xy\sqrt{y}[/tex]

Add similar elements

                                        [tex]=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]

Therefore, we conclude that:

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]

Hence, option B is true.

Answer:

x = 11

Step-by-step explanation:

Remark

There are two legs. They are equal.

Equation

2x - 4 + 2x - 4 +x = 47                   Combine like terms

Solution

5x - 8 = 47

5x - 8+8 = 47 + 8

5x = 55                                           Divide by 5

x = 11

Answer:

(1.135)^[tex]^1/12[/tex]

Step-by-step explanation:

The monthly interest rate is 1.125%

What is rate of change?

The rate of change of a function is the rate at which the output values change over the input value.

The rate of change of a function is one degree less than the actual function.

Here, it is given that :

a credit card company charges 13.5% yearly interest

therefore, to find the rate of interest charged per month divide 13.5% with 12 :

rate of interest charged per month = 13.5%/12

rate of interest charged per month = 1.125%

Therefore, the monthly interest rate is 1.125%

Answer:

Step-by-step explanation:

The quotient of zero and one is 0/1 = 0.

A number times itself is written as n^2, where n is the number.  This is the same as n*n.

Answer:

The dimensional analysis method uses equivalences written in fractional form. Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label). In order for units to cancel they must be in the numerator and the denominator of the fraction

Step-by-step explanation:

Dimensional analysis is a method of problem solving that takes into consideration the identity property of multiplication whereby the product of a number and 1 will always give the same number, that is 1 × n = n whereby the value "n" remains the same after the multiplication

Therefore, a fraction of two equivalent measurements but different units has a value of 1, and multiplying the equivalent fraction with another measurement with the same unit as the denominator of the fraction with a value of 1 changes the unit to that of the unit of the numerator

B is the answer i got 90%

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Under a clockwise rotation about the origin of 90°

a point (x, y ) → (y, - x ) , then

R(2, - 1 ) → R'(- 1, - 2 )

S(4, 0 ) → (0, - 4 )

T(1, 3 ) → T'(3, - 1 )

x=9/34 that's the answer

Answer: 2J - 5

Step-by-step explanation:

The number of cards that Jacob has = J

Melissa has 5 fewer cards than Jacob. Melissa card will be: = J - 5

The expression that shows the number of cards they have together will be gotten by adding their cards together. This will be:

= J + (J - 5)

= J + J - 5

= 2J - 5

Answer:

x=9

z=105

Step-by-step explanation:

12x-33=75

12x=75+33

x=108/12

x=9

z+75=180

z=180-75

z=105

Answer:

5/2

Step-by-step explanation:

10 multiplied by 5/2 gives us 25, so the scale factor is 5/2.

Answer:

The expression that matches the situation is 90.00 - 3x ⇒ 1st answer

Step-by-step explanation:

Let us solve the question

∵ You went to the mall with $90.00

→ That means the total money with you  = $90.00

∴ The total money = 90.00 dollars

∵ You bought three shirts that cost x dollars each

∴ The cost of a shirt = $x

∴ The number of shirts = 3

→ Find the total cost of the three shirts

∴ The cost of the shirts = 3 × x

∴ The cost of the shirts = 3x dollars

∵ The money left = the total money - the cost of the shirts

→ Substitute the value of total money and the cost of the shirts

∴ The amount of money left = 90.00 - 3x

∴ You have left with 90.00 - 3x dollars

∴ The expression matches the situation is 90.00 - 3x dollars

Answer:

x < -10/3 OR x > 20/3

Step-by-step explanation:

|5 - 3x| - 3 > 12

|5 - 3x| > 15

since it's absolute value, you have 2 scenarios to solve:

1) 5 - 3x > 15

-3x > 10

x < -10/3  (when dividing or multiplying by a negative, switch the symbol)

2) -(5 - 3x) > 15

-5 + 3x > 15

3x > 20

x > 20/3

Answer: 104 yards

Step-by-step explanation:

First and foremost, we need.to know that: 1 yard = 3 feet

Since she wants each balloon string to be 6 feet long and she wants to get 52 balloons. The total feet that is required for the balloon would be:

= 52 × 6

= 312 feet

Then we convert 312 feet to yard. This would be:

= 312 feet / 3 feet

= 104 yards
