Step-by-step explanation:
Recall that [tex]7^a\cdot 7^b = 7^{a+b}[/tex]
So now
[tex]7^{2/3} \cdot 7^{1/3}\\= 7^{\frac{2}{3}+\frac{1}{4}}\\=7^{\frac{8}{12}+\frac{3}{12}}\\=7^{11/12}[/tex]
The equivalent value of the expression is A = 7^ ( 11/12 )
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Let the first number be p = 7 ^ ( 2/3 )
Let the second number be q = 7 ^ ( 1/4 )
And , A = pq
On simplifying , we get
A = 7 ^ ( 2/3 ) . 7 ^ ( 1/4 )
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
So , A = 7 ^ ( 2/3 + 1/4 )
A = 7 ^ ( 11/12 )
Hence , the equation is 7^ ( 11/12 )

Answer: celsius = 5/9 (Fahrenheit - 32)
Step-by-step explanation:
Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)
So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.
Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)
You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.
I hope that makes sense!

The Solution of the Inequality is y> 2.1.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
Inequality: 2y + 7 > 15.2
Now, simplifying the inequality
2y > 15.2-7
2y > 8.2
y> 8.2 /2
y> 2.1
So, the solution is y>2.1

Solve T = M(7 + FG) for F

(Answer quickly)
Answers
Answer:
F = (T - 7M) ÷ MG
Step-by-step explanation:
T = M(7 + FG)
T = 7M + MFG
T - 7M = MFG
(T - 7M) ÷ MG = F
F = (T - 7M) ÷ MG
Answer:
Step-by-step explanation:
Remove the brackets
T = 7M + FGM Subtract 7M from both sides
T - 7M = FGM Divide both sides by GM
T - 7M

F = (T - 7M)/GM
A bowl holds the 15 pieces of fruit shown below.
If Jasmine correctly writes the fraction of fruit that are apples, which of the following would be the numerator of the fraction?
Answers
Answer:
Step-by-step explanation:
8/15
The fraction representing the number of apples is 8/15 thus, the numerator will be 8.
What is numerator and denominator?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.
As per the given apple lot,
The total number of fruits = 20
The total number of apples = 8
Thus, the fraction will be 8/20 where the numerator will be 8.
Hence "The fraction representing the number of apples is 8/15 thus, the numerator will be 8".
