Answer:

<em>n = 4</em>

Step-by-step explanation:

<u>Properties of Exponents</u>

We are required to solve the following equation:

\displaystyle 7^7\cdot 7^5=\frac{(7^n)^4}{7^4}

Operating:

\displaystyle 7^{7+5}=\frac{7^{4n}}{7^4}

\displaystyle 7^{12}=7^{4n-4}

Equating the exponents:

4n - 4 = 12

Adding 4:

4n = 16

Dividing by 4:

n = 4

Please help. What is the answer?
Gala2k [10]

Answer:

ASA

Step-by-step explanation:

The longest side is the same (denoted by the small line).

Assuming the red dot and the x mean the angles are the same, the triangles share two common angles.

As such, the triangles share one common side and two common angles. Hence ASA

1. A farmer is planting a 47-acre field of green beans. How many seeds must be purchased if the farmer plants 140,000 seeds per
Sedaia [141]

Answer:

Step-by-step explanation:

There are 47 acres and the farmer is planting 140,000 per acre.

You got to times 140,000 by 47 but you can multiply 14 by 47 instead and place the zero later.

So take 10 times 47 and that is 470

Then take 4 times 47 and that is 188

Add 470 and 188 and you get 658

Take 658 a place the four zeros and you get 6,580,000 seed

A woman bought a dress at a discount of 16 2/3%. If the woman paid $32.50, what was the original price of the dress?
Anastaziya [24]

Let's let x equal the original price of the dress.


We know that 16.6666% is equal to 0.16666 in decimal form by dividing the percent by 100.


So we can set up the equation:


x-0.16666x=32.50


because we know the discount, and we know that the discount of the original price was subtracted from the original price.


So then let's simplify by taking out x, the common factor:


x(1-0.16666)=32.50


Then solve for x:


x(0.83333)=32.50


\frac{x(0.83333)}{0.83333} =\frac{32.50}{0.83333}


x=39


So now we know that the original price of the dress was $39.
