The equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have
to determine the equivalent expression:
The expression is given as:
(5ab)^3/30ab^-7
Expand the numerator
(5ab)^3/30ab^-7
= 125 a^3b^3/30ab^-7
Divide 125 and 30 by 5
(5ab)^3/30ab^-7
=25 a^3b^3/6ab^-7
Apply the law of indices
(5ab)^3/30ab^-7
=25 a^(3-1) b^(3+7) /6
Evaluate the exponent
(5ab)^3/30ab^-7
=25 a^2b^10/6
Hence, the equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.

if 3x/4 - 13 = -9 then what is the value of x^2
show work!
Answer:
When 3x/4 - 13 = -9, x² = 256/9.
Step-by-step explanation:
3x/4 - 13 = -9
Multiply the expression by 4.
3x - 52 = -36
Add 52 to both sides.
3x = 16
Divide both sides by 3.
x = 16/3
Knowing x, let's square it.
(16/3)²
Apply the power to fraction rule.
16²/3²
Evaluate the powers.
256/9.

7 trigonometric ratio
Answer:
Option C
Step-by-step explanation:
From the diagram : -
Angle ( θ ) = 30
Opposite side = 16
Adjacent side = x
To find : x = ?
Formula : -
tan θ = Opposite side / Adjacent side
Note : -
The value of tan 30 is :
1 / √3 ( In fraction )
0.57735 ( In decimal )
Tan 30 = 16 / x
0.57735 = 16 / x
x = 16 / 0.57735
x = 27.7128258422
27.7128258422 ~ 27.7
27.7128258422 is approximately 27.7
Therefore,
x = 27.7
6.1% of 40 is what number
Answer:
6.1% of 40 is 2.4
Step-by-step explanation:
You can find the percentage by looking at 40 as 100% and then taking 6.1% of that. That is adding 6.1 to 0, so it's just 6.1%.
It would be like asking what is 10% of 30? 30 is 100%, so 10% becomes 3, which would be your answer.
Answer:
6.1\ 100 = x/40
6.1*40= 244
244 divided 100

write an equation in slope intercept form of the line that passes through the given points (3,3) and (0,1)
Answer: y = 2/3x + 1
Step-by-step explanation: Slope is always slope = Change in y/Change in x
The change in y (the second point) is 2, and the change in x (the first point) is 3. Our y intercept is 1, so it will pass through (0,1)

Answer:
x = 20
(5x + 2) = 102º
(3x + 5) = 65º
(8x + 8) = 168º
(4x + 15) = 95º
(5x + 10) = 110º
Step-by-step explanation:
(5x + 2) + (3x + 5) + (8x + 8) + (4x + 15) + (5x + 10) = 540
Group like terms
(5x + 3x + 8x + 4x + 5x) + (2 + 5 + 8 + 15 + 10) = 540
Simplify
25x + 40 = 540
Subtract 40 from both sides
25x = 500
Divide both sides by 25
x = 20
--------------------
Now that x has been determined the angles can be found
(5x + 2) = 5*20 + 2 = 102º
(3x + 5) = 3*20 + 5 = 65º
(8x + 8) = 8*20 + 8 = 168º
(4x + 15) = 20*4 + 15 = 95º
(5x + 10) = 5*20 + 10 = 110º

highest common factor of 16 and 50
Answer:
2
Explanation:
GCF of 16 and 50 is 2. The highest common factor is also known as the great common factor.
The highest common factor of the numbers 16 and 50 is 2.
What is the highest common factor?The greatest positive integer that divides two or more integers without producing a remainder is known as the highest common factor (HCF). Also, it is known as the largest common divisor (GCD).
To find the highest common factor (HCF) of 16 and 50, we can use a method called prime factorization.
First, we can find the prime factorization of each number:
16 = 2 × 2 × 2 × 2
50 = 2 × 5 × 5
Next, we can identify the common factors between the two prime factorizations. The only common factor is the factor of 2, which appears in both prime factorizations.
Therefore, the highest common factor of 16 and 50 is 2.

Boats from all along the Atlantic coast dock at a busy marina. Of the first 13 boats to dock at the marina one day, 5 were from North Carolina. What is the experimental probability that the next boat to dock will be from North Carolina?
Using it's concept, the experimental probability that the next boat to dock will be from North Carolina is given by: 5/13.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, there are 13 boats, of which 5 were from North Carolina, hence the experimental probability that the next boat to dock will be from North Carolina is given by: 5/13.
